The fin body 1 includes an air outlet contour line 13 arranged at one side and an air inlet contour line 12 arranged at the other side; and the fin body 1 is provided with refrigerant pipe mounting holes 11 for allowing refrigerant pipes to be mounted. The fin body 1 is concave in a direction from an air inlet side to an air outlet side, forming a curved shape. The distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1, on a straight line of a curvature radius of the air outlet contour line 13 of the fin body 1 or on a straight line of a curvature radius of the air inlet contour line 12 of the fin body 1, gradually decreases from a center to flanks of the heat exchanger fin. Accordingly, an internal diameter of the refrigerant pipe mounting hole 11 also gradually decreases from the center to the flanks of the heat exchanger fin; and the air inlet contour line 12 and the air outlet contour line 13 are connected by arcs at the flanks of the heat exchanger fin. There is a unique maximum value H3 for the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1. Along a direction from a first end to a second end of the air inlet contour line 12, the maximum distance point 14 is within ⅕ to ⅘ of the air inlet contour line 12; and a straight line where the maximum distance point 14 is located extends along an air inlet direction for the heat exchanger fin. In specific, the maximum distance point 14 is located within a region where an air volume of an inlet air flow is maximum, thus allowing to increase a size of a region of the fin body 1 where the air volume is high and to reduce a size of a region of the fin body 1 where the air volume is low, to improve utilization of the fin body 1, so that heat transfer efficiency is improved when the fin body 1 is provided with the refrigerant pipes. It should be noted that, as shown in FIG. 1, the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 each are provided with a process notch 15, to facilitate tailoring of the fin body 1 during processing.
Embodiment 2
[0067] In this embodiment, there is provided a heat exchanger fin. As shown in FIG. 2, the heat exchanger fin includes an integrally-formed fin body 1. The fin body 1 includes an air outlet contour line 13 arranged at one side and an air inlet contour line 12 arranged at the other side; and the fin body 1 is provided with refrigerant pipe mounting holes 11 for allowing refrigerant pipes to be mounted. The fin body 1 is concave in a direction from an air inlet side to an air outlet side, forming a curved shape. The distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1, on a straight line of a curvature radius of the air outlet contour line 13 of the fin body 1 or on a straight line of a curvature radius of the air inlet contour line 12 of the fin body 1, gradually decreases from a center to flanks of the heat exchanger fin. Accordingly, an internal diameter of the refrigerant pipe mounting hole 11 also gradually decreases from the center to the flanks of the heat exchanger fin; and the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 corresponding to the refrigerant pipe mounting hole 11 is positively correlated with the internal diameter of the refrigerant pipe mounting hole 11. The air inlet contour line 12 and the air outlet contour line 13 are connected by arcs at the flanks of the heat exchanger fin. There is a unique maximum value H3 for the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1. Along a direction from a first end to a second end of the air inlet contour line 12, the maximum distance point 14 is within ⅕ to ⅘ of the air inlet contour line 12; and a straight line where the maximum distance point 14 is located extends along an air inlet direction for the heat exchanger fin. In specific, the maximum distance point 14 is located within a region where an air volume of an inlet air flow is maximum, thus allowing to increase a size of a region of the fin body 1 where the air volume is high and to reduce a size of a region of the fin body 1 where the air volume is low, to improve utilization of the fin body 1, so that heat transfer efficiency is improved when the fin body 1 is provided with the refrigerant pipe. In addition, at the maximum distance point 14, on the straight line of the curvature radius of the air outlet contour line 13 of the fin body 1 or on the straight line of the curvature radius of the air inlet contour line 12 of the fin body 1, the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 is H3, corresponding to which the internal diameter of the refrigerant pipe mounting hole 11 is P1; while at a first position point 17, on the straight line of the curvature radius of the air outlet contour line 13 of the fin body 1 or on the straight line of the curvature radius of the air inlet contour line 12 of the fin body 1, the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 is H4, corresponding to which the internal diameter of the refrigerant pipe mounting hole 11 is P2, where H3>H4 and P1>P2. In other words, the longer the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 is, the larger the internal diameter of the corresponding refrigerant pipe mounting hole 11 is. It should be noted that, as shown in FIG. 2, the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 each are provided with a process notch 15, to facilitate tailoring of the fin body 1 during processing.

[0068] In this embodiment, there is provided a heat exchanger fin. As shown in FIG. 3, the heat exchanger fin includes an integrally-formed fin body 1. The fin body 1 includes an air outlet contour line 13 arranged at one side and an air inlet contour line 12 arranged at the other side; and the fin body 1 is provided with refrigerant pipe mounting holes 11 for allowing refrigerant pipes to be mounted. The fin body 1 is concave in a direction from an air inlet side to an air outlet side, forming a curved shape. The distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 on a straight line of a curvature radius of the air outlet contour line 13 of the fin body 1 or on a straight line of a curvature radius of the air inlet contour line 12 of the fin body 1, gradually decreases from a center to flanks of the heat exchanger fin. Accordingly, an internal diameter of the refrigerant pipe mounting hole 11 also gradually decreases from the center to the flanks of the heat exchanger fin; and the internal diameter of each refrigerant pipe mounting hole 11 is linear-positively correlated with a distance of circle centers between any two adjacent refrigerant pipe mounting holes 11. The air inlet contour line 12 and the air outlet contour line 13 are connected by arcs at the flanks of the heat exchanger fin.
[0069] There is a unique maximum value H3 for the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1. Along a direction from a first end to a second end of the air inlet contour line 12, the maximum distance point 14 is within ⅕ to ⅘ of the air inlet contour line 12; and a straight line where the maximum distance point 14 is located extends along an air inlet direction for the heat exchanger fin. In specific, the maximum distance point 14 is located within a region where an air volume of an inlet air flow is maximum, thus allowing to increase a size of a region of the fin body 1 where the air volume is high and to reduce a size of a region of the fin body 1 where the air volume is low, to improve utilization of the fin body 1, so that heat transfer efficiency is improved when the fin body 1 is provided with the refrigerant pipe. In addition, at the maximum distance point 14, on the straight line of the curvature radius of the air outlet contour line 13 of the fin body 1 or on the straight line of the curvature radius of the air inlet contour line 12 of the fin body 1, the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 is H3; the distance of circle centers between two adjacent refrigerant pipe mounting holes 11 is Q1, corresponding to which the internal diameter of the refrigerant pipe mounting hole is P1; while at a first position point 17, on the straight line of the curvature radius of the air outlet contour line 13 of the fin body 1 or on the straight line of the curvature radius of the air inlet contour line 12 of the fin body 1, the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 is H4; the distance of circle centers between two adjacent refrigerant pipe mounting holes 11 is Q2, corresponding to which the internal diameter of the refrigerant pipe mounting hole is P2, where H3>H4, Q1>Q2 and P1>P2. In other words, the longer the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 is, the greater the distance of circle centers between adjacent refrigerant pipe mounting holes 11 is, and the larger the internal diameter of the corresponding refrigerant pipe mounting hole 11 is. It should be noted that, as shown in FIG. 3, the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 each are provided with a process notch 15, to facilitate tailoring of the fin body 1 during processing.
Embodiment 4
[0070] In this embodiment, there is provided a heat exchanger fin. As shown in FIG. 1, the heat exchanger fin includes an integrally-formed fin body 1. The fin body 1 includes an air outlet contour line 13 arranged at one side and an air inlet contour line 12 arranged at the other side; and the fin body 1 is provided with refrigerant pipe mounting holes 11 for allowing refrigerant pipes to be mounted. The fin body 1 is concave in a direction from an air inlet side to an air outlet side, forming a curved shape. The distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1, on a straight line of a curvature radius of the air outlet contour line 13 of the fin body 1 or on a straight line of a curvature radius of the air inlet contour line 12 of the fin body 1, gradually decreases from a center to flanks of the heat exchanger fin. Accordingly, an internal diameter of the refrigerant pipe mounting hole 11 also gradually decreases from the center to the flanks of the heat exchanger fin; and the air inlet contour line 12 and the air outlet contour line 13 are connected by arcs at the flanks of the heat exchanger fin. There is a unique maximum value H3 for the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1. Along a direction from a first end to a second end of the air inlet contour line 12, the maximum distance point 14 is within ⅕ to ⅘ of the air inlet contour line 12; and a straight line where the maximum distance point 14 is located extends along an air inlet direction for the heat exchanger fin. In specific, the maximum distance point 14 is located within a region where an air volume of an inlet air flow is maximum, thus allowing to increase a size of a region of the fin body 1 where the air volume is high and to reduce a size of a region of the fin body 1 where the air volume is low, to improve utilization of the fin body 1, so that heat transfer efficiency is improved when the fin body 1 is provided with the refrigerant pipe.
[0071] As shown in FIG. 4, the air inlet contour line 12 of the fin body 1 overlaps with part of the air outlet contour line 13 after translation, to minimize an area of a waste region between two adjacent fin bodies 1 in an entire piece of raw material when processing the fin body 1, with the waste region 5 only existing between the flanks of adjacent fin bodies 1, thus facilitating to improve material utilization and reducing manufacture cost. The air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 each are provided with a process notch 15, to facilitate tailoring of the fin body 1 during processing. The process notch 15 at the air inlet contour line 12 of each fin body 1 corresponds to the process notch 15 at the air outlet contour line 13 of the adjacent fin body 1, for easy tailoring during processing.
[0072] In the present embodiment, during manufacture of the heat exchanger fin, a waste rate can be controlled below 6%, which is even lower than that of traditional non-standard shaped tailoring from a rectangle slice.
Embodiment 5
[0073] In this embodiment, there is provided a heat exchanger fin. As shown in FIG. 1, the heat exchanger fin includes an integrally-formed fin body 1. The fin body 1 includes an air outlet contour line 13 arranged at one side and an air inlet contour line 12 arranged at the other side; and the fin body 1 is provided with refrigerant pipe mounting holes 11 for allowing refrigerant pipes to be mounted. The fin body 1 is concave in a direction from an air inlet side to an air outlet side, forming a curved shape. The distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1, on a straight line of a curvature radius of the air outlet contour line 13 of the fin body 1 or on a straight line of a curvature radius of the air inlet contour line 12 of the fin body 1, gradually decreases from a center to flanks of the heat exchanger fin. Accordingly, an internal diameter of the refrigerant pipe mounting hole 11 also gradually decreases from the center to the flanks of the heat exchanger fin; and the air inlet contour line 12 and the air outlet contour line 13 are connected by arcs at the flanks of the heat exchanger fin. There is a unique maximum value H3 for the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1. Along a direction from a first end to a second end of the air inlet contour line 12, the maximum distance point 14 is within ⅕ to ⅘ of the air inlet contour line 12; and a straight line where the maximum distance point 14 is located extends along an air inlet direction for the heat exchanger fin. In specific, the maximum distance point 14 is located within a region where an air volume of an inlet air flow is maximum, thus allowing to increase a size of a region of the fin body 1 where the air volume is high and to reduce a size of a region of the fin body 1 where the air volume is low, to improve utilization of the fin body 1, so that heat transfer efficiency is improved when the fin body 1 is provided with the refrigerant pipe.
[0074] As shown in FIG. 4, the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 each are provided with a process notch 15, to facilitate tailoring of the fin body 1 during processing. The air inlet contour line 12 of the fin body 1 exactly overlaps with part of the air outlet contour line 13 after translation, to minimize an area of a waste region between two adjacent fin bodies 1 in an entire piece of raw material when processing the fin body 1, with the waste region 5 only existing between the flanks of adjacent fin bodies 1.
[0075] As shown in FIG. 1, the entire length of the air inlet contour line 12 of the fin body 1 is divided unequally by the straight line corresponding to the maximum distance, where one part length of the air inlet contour line 12 that is above the straight line corresponding to the maximum distance is longer than the other part length of the air inlet contour line 12 that is below the straight line corresponding to the maximum distance. Accordingly, one part length of the air outlet contour line 13 of the fin body 1 that is above the straight line corresponding to the maximum distance is longer than the other part length of the air outlet contour line 13 that is below the straight line corresponding to the maximum distance. In some examples, the air inlet contour line 12 of the fin body 1 includes five arc segments connected in sequence, and the adjacent arc segments are of gradually decreasing curvatures from the center to the flanks of the heat exchanger fin; accordingly, the air outlet contour line 13 also includes five arc segments connected in sequence, and each arc segment of the air outlet contour line 13 is of a curvature identical to that of the corresponding arc segment of the air inlet contour line 12, and the fin body 1 is divided into five regions with different curvatures from above to below. On the straight line of the curvature radius of the air outlet contour line 13 of the fin body 1, H1, H2, H3, H4 and H5 are respective distances between the air inlet contour line 12 and the air outlet contour line 13 within the five regions, H1<H2<H3, and H5<H4<H3.
[0076] In some examples, a plane where the air inlet direction for the fin body 1 is located is referred to as a first plane 61, i.e., the horizontal plane as shown in FIG. 1 is the first plane 61; a plane which is perpendicular to the first plane 61 is a second plane 62, i.e., the vertical plane as shown in FIG. 1 is the second plane 62. The fin body 1 is of a projection size L1 on the second plane 62; the part of the fin body 1 above the straight line corresponding to the maximum distance is of a projection size L2 on the first plane 61 and a projection size L5 on the second plane 62; and the part of the fin body 1 below the straight line corresponding to the maximum distance is of a projection size L3 on the first plane 61 and a projection size L4 on the second plane 62, where L3<L2<L1 and L4<L5.
[0077] It should be noted that, for the heat exchanger fin in this embodiment, the related projection size may also comply with L2≤L3 and/or L5≤L4. In some examples, the fin body 1 may also be symmetrical relative to the straight line corresponding to the maximum distance.
[0078] On the straight line of the curvature radius of the air outlet contour line 13 of the fin body 1 or on the straight line of the curvature radius of the air inlet contour line 12 of the fin body 1, there is the maximum distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1. The straight line where the maximum distance is located is the straight line corresponding to the maximum distance.
Embodiment 6

The fin body 1 includes an air outlet contour line 13 arranged at one side and an air inlet contour line 12 arranged at the other side; and the fin body 1 is provided with refrigerant pipe mounting holes 11 for allowing refrigerant pipes to be mounted. The fin body 1 is concave in a direction from an air inlet side to an air outlet side, forming a curved shape. The distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1, on a straight line of a curvature radius of the air outlet contour line 13 of the fin body 1 or on a straight line of a curvature radius of the air inlet contour line 12 of the fin body 1, gradually decreases from a center to flanks of the heat exchanger fin. Accordingly, an internal diameter of the refrigerant pipe mounting hole 11 also gradually decreases from the center to the flanks of the heat exchanger fin; and the air inlet contour line 12 and the air outlet contour line 13 are connected by arcs at the flanks of the heat exchanger fin. The heat exchanger fin is formed as an equidistant region 16 at the center. Within the equidistant region 16, the distance between the air inlet contour line 12 and the air outlet contour line 13 is equal on the straight line of the curvature radius of the air outlet contour line 13 of the fin body 1. In other words, there are more than one maximum distance H3 between the air inlet contour line 12 and the air outlet contour line 13; and all maximum distance points 14 are within ⅕ to ⅘ of the air inlet contour line 12 along a first end to a second end of the air inlet contour line 12. In specific, the air inlet contour line 12 and the air outlet contour line 13 within the equidistant region 16 are arcs, which are concave in the direction from the air inlet side to the air outlet side. The equidistant region 16 is located at the center where an air volume of an inlet air flow is maximum, thus allowing to increase a size of a region of the fin body 1 where the air volume is high and to reduce a size of a region of the fin body 1 where the air volume is low, to improve utilization of the fin body 1, so that heat transfer efficiency is improved when the fin body 1 is provided with the refrigerant pipe. It should be noted that, as shown in FIG. 5, the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 each are provided with a process notch 15, to facilitate tailoring of the fin body 1 during processing.

The distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1, on a straight line of a curvature radius of the air outlet contour line 13 of the fin body 1 or on a straight line of a curvature radius of the air inlet contour line 12 of the fin body 1, gradually decreases from a center to flanks of the heat exchanger fin. Accordingly, an internal diameter of the refrigerant pipe mounting hole 11 also gradually decreases from the center to the flanks of the heat exchanger fin; and the air inlet contour line 12 and the air outlet contour line 13 are connected by arcs at the flanks of the heat exchanger fin. The heat exchanger fin is formed as an equidistant region 16 at the center. Within the equidistant region 16, the distance between the air inlet contour line 12 and the air outlet contour line 13 is equal on the straight line of the curvature radius of the air outlet contour line 13 of the fin body 1. In other words, there are more than one maximum distance H3 between the air inlet contour line 12 and the air outlet contour line 13; and all maximum distance points 14 are within ⅕ to ⅘ of the air inlet contour line 12 along a first end to a second end of the air inlet contour line 12. In specific, the air inlet contour line 12 and the air outlet contour line 13 within the equidistant region 16 are straight lines, which are perpendicular to an air inlet direction. The equidistant region 16 is located at the center where an air volume of an inlet air flow is maximum, thus allowing to increase a size of a region of the fin body 1 where the air volume is high and to reduce a size of a region of the fin body 1 where the air volume is low, to improve utilization of the fin body 1, so that heat transfer efficiency is improved when the fin body 1 is provided with the refrigerant pipe. It should be noted that, as shown in FIG. 6, the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 each are provided with a process notch 15, to facilitate tailoring of the fin body 1 during processing.

The distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1, on a straight line of a curvature radius of the air outlet contour line 13 of the fin body 1 or on a straight line of a curvature radius of the air inlet contour line 12 of the fin body 1, gradually decreases from a center to flanks of the heat exchanger fin. Accordingly, an internal diameter of the refrigerant pipe mounting hole 11 also gradually decreases from the center to the flanks of the heat exchanger fin; and the air inlet contour line 12 and the air outlet contour line 13 are connected by arcs at the flanks of the heat exchanger fin. There is a unique maximum value H3 for the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1. Along a direction from a first end to a second end of the air inlet contour line 12, the maximum distance point 14 is within ⅕ to ⅘ of the air inlet contour line 12; and a straight line where the maximum distance point 14 is located extends along an air inlet direction for the heat exchanger fin. In specific, the maximum distance point 14 is located within a region where an air volume of an inlet air flow is maximum, thus allowing to increase a size of a region of the fin body 1 where the air volume is high and to reduce a size of a region of the fin body 1 where the air volume is low, to improve utilization of the fin body 1, so that heat transfer efficiency is improved when the fin body 1 is provided with the refrigerant pipe. A distance between adjacent refrigerant pipe mounting holes 11 is positively correlated with a diameter of the refrigerant pipe mounting hole 11, i.e., the larger the diameter of the refrigerant pipe mounting hole 11 is, the longer the distance between adjacent refrigerant pipe mounting holes 11 is.
[0082] As shown in FIG. 4, the air inlet contour line 12 of the fin body 1 exactly overlaps with part of the air outlet contour line 13 after translation, to minimize an area of a waste region between two adjacent fin bodies 1 in an entire piece of raw material when processing the fin body 1, with the waste region 5 only existing between the flanks of adjacent fin bodies 1. The air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 each are provided with a process notch 15. The process notch 15 at the air inlet contour line 12 of each fin body 1 corresponds to the process notch 15 at the air outlet contour line 13 of the adjacent fin body 1, for easy tailoring during processing.
[0083] As shown in FIG. 1, the entire length of the air inlet contour line 12 of the fin body 1 is divided unequally by the straight line corresponding to the maximum distance, where one part length of the air inlet contour line 12 that is above the straight line corresponding to the maximum distance is longer than the other part length of the air inlet contour line 12 that is below the straight line corresponding to the maximum distance. Accordingly, one part length of the air outlet contour line 13 of the fin body 1 that is above the straight line corresponding to the maximum distance is longer than the other part length of the air outlet contour line 13 that is below the straight line corresponding to the maximum distance. In specific, the air inlet contour line 12 of the fin body 1 includes five arc segments connected in sequence, and the adjacent arc segments are of gradually decreasing curvatures from the center to the flanks of the heat exchanger fin; accordingly, the air outlet contour line 13 of the fin body 1 also includes five arc segments connected in sequence, and each arc segment of the air outlet contour line 13 is of a curvature identical to that of the corresponding arc segment of the air inlet contour line 12, and the fin body 1 is divided into five regions with different curvatures from above to below. On the straight line of the curvature radius of the air outlet contour line 13 of the fin body 1, H1, H2, H3, H4 and H5 are respective distances between the air inlet contour line 12 and the air outlet contour line 13 within the five regions, where H3 is the maximum distance, H1<H2<H3, and H5<H4<H3. Further, a plane where the air inlet direction for the fin body 1 is located is referred to as a first plane 61, i.e., the horizontal plane as shown in FIG. 1 is the first plane 61, a plane perpendicular to the first plane 61 is a second plane 62, i.e., the vertical plane as shown in FIG. 1 is the second plane 62. The fin body 1 is of a projection size L1 on the second plane 62; the part of the fin body 1 above the straight line corresponding to the maximum distance is of a projection size L2 on the first plane 61 and a projection size L5 on the second plane 62; and the part of the fin body 1 below the straight line corresponding to the maximum distance is of a projection size L3 on the first plane 61 and a projection size L4 on the second plane 62, where L3<L2<L1 and L4<L5.
[0084] It should be noted that, for the heat exchanger fin in this embodiment, the related projection size may also comply with L2≤L3 and/or L5≤L4. In some example, the fin body 1 may also be symmetrical relative to the straight line corresponding to the maximum distance.
[0085] On the straight line of the curvature radius of the air outlet contour line 12 of the fin body or on the straight line of the curvature radius of the air inlet contour line of the fin body, there is the maximum distance between the air inlet contour line and the air outlet contour line of the fin body. The straight line where the maximum distance is located is the straight line corresponding to the maximum distance.
Embodiment 9
[0086] In this embodiment, there is provided a heat exchanger fin. As shown in FIG. 1, the heat exchanger fin includes an integrally-formed fin body 1. The fin body 1 includes an air outlet contour line 13 arranged at one side and an air inlet contour line 12 arranged at the other side; and the fin body 1 is provided with refrigerant pipe mounting holes 11 for allowing refrigerant pipes to be mounted. The fin body 1 is concave in a direction from an air inlet side to an air outlet side, forming a curved shape. The distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1, on a straight line of a curvature radius of the air outlet contour line 13 of the fin body 1 or on a straight line of a curvature radius of the air inlet contour line 12 of the fin body 1, gradually decreases from a center to flanks of the heat exchanger fin. Accordingly, an internal diameter of the refrigerant pipe mounting hole 11 also gradually decreases from the center to the flanks of the heat exchanger fin; the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 corresponding to the refrigerant pipe mounting hole 11 is positively correlated with the internal diameter of the refrigerant pipe mounting hole 11; and the internal diameter of each refrigerant pipe mounting hole 11 is linear-positively correlated with a distance of circle centers between any two adjacent refrigerant pipe mounting holes 11. The air inlet contour line 12 and the air outlet contour line 13 are connected by arcs at the flanks of the heat exchanger fin. There is a unique maximum value H3 for the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1. Along a direction from a first end to a second end of the air inlet contour line 12, the maximum distance point 14 is within ⅕ to ⅘ of the air inlet contour line 12; and a straight line where the maximum distance point 14 is located extends along an air inlet direction for the heat exchanger fin.
[0087] In specific, as shown in FIG. 3, the maximum distance point 14 is located within a region where an air volume of an inlet air flow is maximum, thus allowing to increase a size of a region of the fin body 1 where the air volume is high and to reduce a size of a region of the fin body 1 where the air volume is low, to improve utilization of the fin body 1, so that heat transfer efficiency is improved when the fin body 1 is provided with the refrigerant pipe. In addition, at the maximum distance point 14, on the straight line of the curvature radius of the air outlet contour line 13 of the fin body 1 or on the straight line of the curvature radius of the air inlet contour line 12 of the fin body 1, the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 is H3, corresponding to which the internal diameter of the refrigerant pipe mounting hole 11 is P1, and the distance of circle centers between two adjacent refrigerant pipe mounting holes 11 is Q1; while at a first position point 17, on the straight line of the curvature radius of the air outlet contour line 13 of the fin body 1 or on the straight line of the curvature radius of the air inlet contour line 12 of the fin body 1, the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 is H4, corresponding to which the internal diameter of the refrigerant pipe mounting hole 11 is P2, and the distance of circle centers between two adjacent refrigerant pipe mounting holes 11 is Q2, where H3>H4, P1>P2 and Q1>Q2. In other words, the longer the distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 is, the greater the distance of circle centers between two adjacent refrigerant pipe mounting holes 11 is, and the larger the internal diameter of the corresponding refrigerant pipe mounting hole 11 is.
[0088] As shown in FIG. 4, the air inlet contour line 12 of the fin body 1 exactly overlaps with part of the air outlet contour line 13 after translation, to minimize an area of a waste region between two adjacent fin bodies 1 in an entire piece of raw material when processing the fin body 1, with the waste region 5 only existing between the flanks of adjacent fin bodies 1. The air inlet contour line 12 and the air outlet contour line 13 of the fin body 1 each are provided with a process notch 15. The process notch 15 at the air inlet contour line 12 of each fin body 1 corresponds to the process notch 15 at the air outlet contour line 13 of the adjacent fin body 1, for easy tailoring during processing.
[0089] As shown in FIG. 1, the entire length of the air inlet contour line 12 of the fin body 1 is divided unequally by the straight line corresponding to the maximum distance, where one part length of the air inlet contour line 12 that is above the straight line corresponding to the maximum distance is longer than the other part length of the air inlet contour line 12 that is below the straight line corresponding to the maximum distance. Accordingly, one part length of the air outlet contour line 13 of the fin body 1 that is above the straight line corresponding to the maximum distance is longer than the other part length of the air outlet contour line 13 that is below the straight line corresponding to the maximum distance. In specific, the air inlet contour line 12 of the fin body 1 includes five arc segments connected in sequence, and the adjacent arc segments are of gradually decreasing curvatures from the center to the flanks of the heat exchanger fin; accordingly, the air outlet contour line 13 also includes five arc segments connected in sequence, and each arc segment is of a curvature identical to that of the corresponding arc segment at the air inlet contour line 12, and the fin body 1 is divided into five regions with different curvatures from above to below. On the straight line of the curvature radius of the air outlet contour line 13 of the fin body 1, H1, H2, H3, H4 and H5 are respective distances between the air inlet contour line 12 and the air outlet contour line 13 within the five regions, where H3 is the maximum distance, H1<H2<H3, and H5<H4<H3. Further, a plane where the air inlet direction for the fin body 1 is located is referred to as a first plane 61, i.e., the horizontal plane as shown in FIG. 1 is the first plane 61, a plane which is perpendicular to the first plane 61 is a second plane 62, i.e., the vertical plane as shown in FIG. 1 is the second plane 62. The fin body 1 is of a projection size L1 on the second plane 62; the part of the fin body 1 above the straight line corresponding to the maximum distance is of a projection size L2 on the first plane 61 and a projection size L5 on the second plane 62; and the part of the fin body 1 below the straight line corresponding to the maximum distance is of a projection size L3 on the first plane 61 and a projection size L4 on the second plane 62, where L3<L2<L1 and L4<L5.
[0090] It should be noted that, for the heat exchanger fin in this embodiment, the related projection size may also comply with L2≤L3 and/or L5≤L4. In some examples, the fin body 1 may also be symmetrical relative to the straight line corresponding to the maximum distance.
[0091] On a straight line of the curvature radius of the air outlet contour line 13 of the fin body 1 or on a straight line of the curvature radius of the air inlet contour line 12 of the fin body 1, there is the maximum distance between the air inlet contour line 12 and the air outlet contour line 13 of the fin body 1. The straight line where the maximum distance is located is the straight line corresponding to the maximum distance.
