DETAILED DESCRIPTION

(13) Several embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that orientational terms such as up, down, left, right, front, rear, inner side, outer side, top, and bottom, which are or may be mentioned in this specification, are defined in combination with the structures shown in the accompanying drawings. They are relative concepts, and therefore may change according to different positions and different usage states. Therefore, these or other orientational terms should not be construed as limiting terms.

(14) As shown in FIG. 3, in general, the structure of a deflector for a condenser according to an embodiment of the present utility model is schematically shown. As can be clearly seen from FIG. 3, the condenser 101 has an inlet 103 in communication with a discharge pipe 102 of a compressor (not shown), and a deflector 104 for guiding a refrigerant gas flow from the compressor is arranged in the condenser 101 and at a position close to the inlet 103. The deflector 104 is fixed to a housing of the condenser 101 by welding or other means.

(15) As can be seen from FIG. 4 and FIG. 5, the deflector 104 is provided with a deflecting structure projecting toward the inlet 103, to reduce the impact force of the high-temperature high-pressure gas flow from the compressor and alleviate the violent vibration caused in the internal structure of the condenser 101. In addition, the propagation direction of noise generated due to the vibration can be changed by the uneven surface of the deflector 104, and therefore the noise level of the condenser 101 can be effectively reduced. In addition, the deflecting structure is designed as impermeable to the refrigerant gas flow. For example, the deflecting structure does not have any pore.

(16) In the embodiment shown in FIGS. 3 to 5, the deflecting structure is approximately configured as a wavy cross section with peaks and troughs, and at least one peak 110 points to the inlet 103, so that the gas flow entering the condenser 101 can be approximately evenly guided to the trough parts on two sides. Preferably, the deflecting structure is arranged on the entire surface of the deflector 104, so as to provide a better vibration and noise reduction effect. Because the wavy cross section of the deflecting structure increases the circulation area, the deflector 104 makes use of the space inside the condenser 101 to a large extent.

(17) FIG. 6 shows a deflector for a condenser according to another specific embodiment of the present utility model. For the position relationship between the inlet 203 of the condenser in communication with the discharge pipe 202 of the compressor and the deflector 204, reference may be made to the description of the foregoing embodiments, and the details will not be repeated herein. As can be clearly seen from FIG. 6 and FIG. 7, in the deflector 204 for a condenser, the deflecting structure has a triangular cross section. Further, the deflecting structure may include a first side plate 211 and a second side plate 212, and the first side plate 211 and the second side plate 212 are of the same size and are symmetrically arranged on the deflector 204 respectively. The top edge formed by the intersection of the first side plate 211 and the second side plate 212 points to the inlet 203. Similarly, after the gas flow entering the condenser reaches the top edge, the gas flow can be approximately evenly guided to the first side plate 211 and the second side plate 212, thus reducing the impact of the high-pressure gas flow on the condenser and reducing noise. Preferably, the deflecting structure is arranged on the entire surface of the deflector 204, so as to provide a better vibration and noise reduction effect. Because the triangular cross section of the deflecting structure increases the circulation area, the deflector 204 makes use of the space inside the condenser to a large extent.

(18) FIG. 8 shows a deflector for a condenser according to still another specific embodiment of the present utility model. For the position relationship between the inlet 303 of the condenser in communication with the discharge pipe 302 of the compressor and the deflector 304, reference may be made to the description of the foregoing embodiments, and the details will not be repeated herein. As can be seen from FIG. 8 and FIG. 9, in the deflector 304 for a condenser, the deflecting structure has a truncated spherical cross section 305. The highest point of the spherical cross section 305 faces directly toward the inlet 303. It should be readily understood that because the spherical surface has a larger guiding area than a plane, the deflector 304 for a condenser in this embodiment has a longer guiding path and can better reduce the impact force of the gas flow from the compressor and reduce the noise level of the condenser. Of course, those skilled in the art can also use a deflecting structure having an irregular spherical cross section instead of the above-mentioned strictly regular spherical cross section.

(19) FIG. 10 shows a deflector for a condenser according to another specific embodiment of the present utility model. For the position relationship between the inlet 403 of the condenser in communication with the discharge pipe 402 of the compressor and the deflector 404, reference may also be made to the description of the foregoing embodiments. As can be seen from FIG. 10 and FIG. 11, in the deflector 404 for a condenser, the deflecting structure has a trapezoidal section. Further, the deflecting structure may include a first side plate 411, a second side plate 412, and a top plate 413. The top plate 413 faces directly toward the inlet 403, and the first side plate 411 and the second side plate 412 are of the same size and are symmetrically arranged on two sides of the top plate 413. The deflector having such a structure can also reduce the impact force of the gas flow from the compressor and reduce the noise level of the condenser.

(20) As an example, for ease of manufacturing, the deflector and the deflecting structure may be integrally formed. In addition, it can be readily figured out by those skilled in the art that the deflecting structure may also be mounted on the deflector for a condenser as an additional component as long as the manufacturing or processing costs permit.

(21) In addition, the present utility model provides a condenser including the above-mentioned deflector for a condenser. Because the deflector is disposed inside the condenser, the condenser is less likely to generate unexpected noise and vibration during running.

(22) In addition, the present utility model further provides a refrigeration system including the above-mentioned condenser. The refrigeration system includes a cooling tower, a water chilling unit, a pumping device, etc. connected through pipelines. The water chilling unit consists of a compressor, a condenser, a throttle device, an evaporator, and the like. As described above, the condenser including the above-mentioned deflector can effectively achieve the objective of vibration and noise reduction without increasing the costs of the water chilling unit. Therefore, the above-mentioned condenser is suitable for use in various refrigeration systems.

(23) Several specific embodiments are provided above to describe in detail the deflector for a condenser, the condenser including the deflector, and the refrigeration system equipped with the condenser of the present utility model. These examples are only used for describing the principles and implementation manners of the present utility model and are not intended to limit the present utility model. Those of ordinary skill in the art can also make various modifications and improvements without departing from the spirit and scope of the present utility model. For example, to enable the deflector to be able to resist the impact of the gas flow, the deflector may be made of steel or other high-strength materials. Therefore, all equivalent technical solutions shall fall within the scope of the present utility model as defined by the appended claims.
