Inverter

Abstract

An inverter is provided. In the inverter, an electronic device is disposed inside a first enclosure; a heat radiator and a cooling fan are disposed inside a second enclosure; a magnetic element is disposed outside the first enclosure and the second enclosure. In this way, the cooling effect on the electronic device inside the first enclosure and the heat radiator inside the second enclosure are increased as they may be less affected by the heat generated by the magnetic element. It is also beneficial to heat dissipation of the magnetic element. The cooling fan blows the heat radiator for heat dissipation; the magnetic element does not block the relatively cold air flowing through the heat radiator. Therefore, a less obstructed air duct is formed, and the dissipation effect is improved.

DETAILED DESCRIPTION OF THE DISCLOSED EXEMPLARY EMBODIMENTS

(5) The exemplary embodiments of the present disclosure are described clearly and completely as follows in conjunction with the accompanying drawings. The described embodiments are only a few rather than all of the embodiments according to the present disclosure. Other embodiments may be obtained by those skilled in the art without any inventive work based on the detailed description of the exemplary embodiments presented herein.

(6) An inverter is provided according to the present disclosure, to address the problem of poor heat dissipation in the conventional technology.

(7) As shown in FIG. 1 and FIG. 2, the inverter includes: an electronic device 101, a magnetic element 102, a heat radiator 103, a cooling fan 104, a first enclosure 201 and a second enclosure 202 connected with each other via a mounting plate 211. The mounting plate 211 is located between the first enclosure 201 and the second enclosure 202. The electronic device 101 is disposed inside the first enclosure 201. The heat radiator 103 and the cooling fan 104 are disposed inside the second enclosure 202, and the magnetic element 102 is disposed outside the first enclosure 201 and the second enclosure 202.

(8) The magnetic element 102 is disposed outside the first enclosure 201 and the second enclosure 202. This may result in a cooling effect on the electronic device 101 inside the first enclosure 201, and the heat radiator 103 inside the second enclosure 202 is less affected by the heat generated by the magnetic element 102. The magnetic element 102 is disposed outside the first enclosure 201 and the second enclosure 202, and is directly contacted with outside air. The heat generated by the magnetic element 102 is easily exchanged with the air, hence, the temperature of the magnetic element 102 is reduced. Thus, it is beneficial to the heat dissipation of the magnetic element 102, and the operational efficiency of the magnetic element 102 is improved. The cooling fan 104 only blows air on the heat radiator 103 for heat dissipation because the magnetic element does not block the relatively cold air flowing through the heat radiator as occurs in the conventional technology. Therefore, a less obstructed air duct is formed, and radiation dissipation is improved.

(9) The magnetic element 102 being disposed outside the first enclosure 201 and the second enclosure 202 may result in a lower heat content for the electronic device 101 inside the first enclosure 201, and the heat radiator 103 inside the second enclosure 202 is less affected by the heat generated by the magnetic element.

(10) In an embodiment, each of the first enclosure 201 and the second enclosure 202 may include the mounting plate 211 to mount a respective device.

(11) In an embodiment, the first enclosure 201 and the second enclosure 202 share one mounting plate 211, and are located on two parallel mounting surfaces of the mounting plate 211 respectively.

(12) The electronic device 101 and the heat radiator 103 are mounted on two parallel mounting surfaces of the mounting plate 211 respectively, and the two parallel mounting surfaces of the mounting plate 211 may be the two surfaces having the largest areas. In some embodiments, the two parallel mounting surfaces of the mounting plate 211 may be two surfaces, for mounting the devices, may not be the two surfaces having the largest areas, however they may be defined depending on the specific application.

(13) The first enclosure 201 and the second enclosure 202 are respectively disposed on the two parallel mounting surfaces of the mounting plate 211 so that the first enclosure 201 and the second enclosure 202 are connected in a back-to-back way. Taking a cuboid as an example for description, both the first enclosure 201 and the second enclosure 202 have five surfaces, and are mounted on a front surface and a back surface of the mounting plate 211.

(14) In some embodiments, the heat radiator 103 is disposed on the mounting plate 211 inside the second enclosure 202 (as shown in FIG. 1); and the electronic device 101 is disposed on the mounting plate 211 inside the first enclosure 201 (as shown in FIG. 2).

(15) As shown in FIG. 1 and FIG. 2, the heat radiator 103 and the electronic device 101 are disposed at two sides of the mounting plate 211 respectively so that the heat radiator 103 and the electronic device 101 are contacted in a back-to-back way via the mounting plated 211. In this way, the heat radiator 103 may operate to dissipate heat for the electronic device 101.

(16) In an embodiment, as shown in FIG. 3, the magnetic element 102 is disposed on a top plate 221 of the second enclosure 202.

(17) The position where the magnetic element 102 is disposed is named as the top plate 221 of the second enclosure 202, and a direction in the description is referred to a placement direction of the inverter when the inverter operates.

(18) The magnetic element 102 is disposed on the top plate 221 of the enclosure and is in direct contacted with outside air. Thus, the heat generated by the magnetic element 102 is easily exchanged with the air. Hence, the temperature of the magnetic element 102 is reduced. It is beneficial to dissipate the heat of the magnetic element 102 because the operational efficiency of the magnetic element 102 is improved.

(19) In an embodiment, as shown in FIG. 1, the cooling fan 104 is disposed on a side plate 222 of the second enclosure 202 inside the second enclosure 202, the side plate 222 being perpendicular to gaps between fins of the heat radiator 103.

(20) The cooling fan 104 may be disposed on the side plate 222 of the second enclosure 202 perpendicular to the gaps between the fins of the heat radiator 103. In this way, it is ensured that the relatively cold air flow generated by the cooling fan 104 may flow through the heat radiator 103 in a large area, which is beneficial to the heat dissipation of the heat radiator 103.

(21) In an embodiment, as shown in FIG. 1, one or more vents are disposed in another side plate 223 of the second enclosure 202, the another side plate 223 is perpendicular to the gaps between the fins of the heat radiator 103.

(22) In an embodiment, as shown in FIG. 1, the number of the vents is more than one, and the vents are uniformly disposed at positions corresponding to the gaps between the fins of the heat radiator 103.

(23) The positions corresponding to the gaps between the fins of the heat radiator 103 correspond to projection of the gaps between the fins of the heat radiator 103 on the side plate 223.

(24) The cooling fan 104 and the vents are disposed at two sides of the heat radiator 103 respectively, so that the cold air flow generated by the cooling fan 104 can pass through the gaps between the fins of the heat radiator 103 and the vents, thus creating an unobstructed air duct, which is beneficial to the heat dissipation of the heat radiator 103.

(25) In an embodiment, the number and positions of the vents may depend on the specific application of the inverter, which is not limited herein.

(26) In an embodiment, as shown in FIG. 2 and FIG. 3, the number of the cooling fans 104 is four.

(27) In an embodiment, the number of the cooling fans 104 is not limited. The cooling fans 104 shown in the drawings show only an example, and the number of cooling fans 104 may depend on the specific application of the inverter.

(28) In the discussion above, the embodiments are described in a progressive manner with the emphasis of each embodiment on an aspect difference from other embodiments. Hence, reference can be made to these similar parts among the embodiments.

(29) The description of the embodiments herein enables those skilled in the art to implement or use the present disclosure. Numerous modifications to the exemplary embodiments are apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without deviating from the spirit or scope of the present disclosure. Therefore, the present disclosure may not be limited to the exemplary embodiments described herein, but in the specification should be interpreted in accordance with the widest scope consistent with the principles and novel features disclosed herein.
