Referring to fig. 1 to 6, a case 100 of an inverter according to an embodiment of the present utility model is described below.

As shown in fig. 1 to 6, a case 100 of an inverter according to an embodiment of the present utility model includes a frame 10 and two covers 20, the frame 10 defining an accommodation space for accommodating an electronic device 200 of the inverter, where the electronic device 200 may be an inverter circuit board or other electronic component, etc., and both sides of the frame 10 in a set direction (for example, front and rear sides as shown in fig. 1) are provided with openings communicating with the accommodation space; the two cover seals 20 are respectively covered at the openings at two sides of the frame body 10, wherein at least one cover seal 20 is a radiator 201, that is, the two cover seals 20 can be both radiators 201, or only one cover seal 20 is a radiator 201, the radiator 201 can rapidly conduct out heat, so that the temperature in the accommodating space is reduced, and the electronic device 200 can be kept in a good working state. When both the cover seals 20 are the heat sink 201, since the hardness and rigidity of the heat sink 201 are both large, the anti-collision performance of the case 100 of the inverter can also be improved, so that the case 100 of the inverter is not easy to deform, and the heat dissipation effect is also better.

By using the heat sink 201 directly as the cover 20, compared with the prior art in which the heat sink is fixed on the inverter casing, the utility model can reduce the use of a side panel, thereby being beneficial to reducing the cost and simplifying the structure, and the heat generated by the electronic device 200 or the heat in the accommodating space can be directly transferred to the heat sink 201, so that the heat transfer efficiency is higher, and the heat dissipation effect is better.

The case 100 of the inverter of the present utility model includes the frame 10 and the cover 20 covering the openings of both sides of the frame 10 in the set direction, and thus, the case 100 of the inverter of the present utility model has a three-layer structure, the structure is simpler, the frame 10 and the cover 20 can be processed separately, and the processing difficulty is low. When the electronic device 200 is installed, the electronic device 200 can be installed on the frame body 10 or on the cover sealing piece 20, the front side and the rear side of the frame body 10 are both openings, and the cover sealing piece 20 is an independent component, so that the assembly difficulty of the electronic device 200 can be reduced when the electronic device 200 is assembled, and the assembly efficiency is improved.

According to the case 100 of the inverter of the embodiment of the utility model, since the radiator 201 is directly arranged on the openings on both sides of the frame 10 in the setting direction as the cover 20, the heat generated by the electronic device 200 or the heat in the accommodating space can be directly transferred to the radiator 201, which is beneficial to improving the radiating speed, and therefore the radiating effect is better; the two cover sealing pieces 20 are adopted to correspond to the openings of the cover sealing frame body 10 at two sides of the set direction, so that a three-layer structure design is formed, the structure of the box body 100 of the inverter is greatly simplified, and meanwhile, the assembly efficiency is higher when the electronic device 200 is assembled, and the operation is more convenient.

According to some embodiments of the present utility model, as shown in fig. 2, the heat sink 201 includes a heat dissipation plate 2011 and a plurality of fins 2012, the heat dissipation plate 2011 is covered at the opening, the plurality of fins 2012 are disposed on a side of the heat dissipation plate 2011 opposite to the frame 10 (i.e. the fins 2012 are disposed on a rear side of the heat dissipation plate 2011 as shown in fig. 1), that is, the plurality of fins 2012 are located outside the accommodating space defined by the frame 10. Thus, when the inverter is mounted on the external mounting surface, the possibility that the heat radiating surface of the inverter is directly in contact with the mounting surface can be reduced, good heat radiation is guaranteed, and meanwhile, the fins 2012 do not occupy the accommodating space defined by the frame 10, so that the self volume of the frame 10 is reduced.

In some embodiments, as shown in fig. 2, the fins 2012 may be rectangular plates, but may also be irregularly shaped, without limitation.

In some embodiments, the side surface of the heat dissipation plate 2011 facing away from the frame 10 may be provided with fins 2012 entirely, or the fins 2012 may be provided only in a partial region on the side surface facing away from the frame 10 as required.

In some embodiments, the heat dissipation plate 2011 and the fins 2012 are all made of aluminum materials, so that the heat conduction speed is high, and the heat dissipation effect is good.

According to some embodiments of the utility model, as shown in fig. 4, a side of the heat sink 2011 facing the receiving space (i.e. a front side of the heat sink 2011 as shown in fig. 1) is provided with mounting locations for mounting at least part of the electronic device 200. That is, some or all of the electronic devices 200 may be directly disposed on the heat dissipation plate 2011, so that the distance between the electronic devices 200 and the heat sink 201 is closer, which is beneficial to increasing the heat transfer speed and improving the heat dissipation efficiency. The electronic device 200 is mounted on the heat dissipation plate 2011, which includes that the electronic device 200, such as a circuit board, is mounted on the heat dissipation plate 2011 through a stud having a certain height, and the electronic device 200 is spaced apart from the heat dissipation plate 2011; the electronic device 200 is directly attached to the heat dissipation plate 2011, and heat generated by the electronic device 200 can be directly conducted to the heat dissipation plate 2011; further, the electric element mounted at a distance from the heat sink 2011 and the electronic device 200 directly mounted in contact with the heat sink 2011 are stacked and spaced apart, and thus the space utilization efficiency of the accommodation space can be improved.

In some embodiments, as shown in fig. 2, a side of the frame body 10 facing the heat sink 201 is provided with a circumferential flange 101, and the heat sink 201 is mounted on the circumferential flange 101 by bolts.

According to some embodiments of the present utility model, as shown in fig. 3, the periphery of at least one side of the frame 10 along the set direction is provided with the flow guide groove 102, for example, the flow guide groove 102 may be provided on either the front side of the frame 10 or the rear side of the frame 10, or both the front side and the rear side of the frame 10 are provided with the flow guide groove 102. The diversion trench 102 extends along the circumferential direction of the opening, and the notch of the diversion trench 102 faces away from the opening in the direction perpendicular to the setting direction, for example, the notch of the diversion trench 102 located at the upper edge of the frame 10 faces upward, the notch of the diversion trench 102 located at the left edge of the frame 10 faces left, the notch of the diversion trench 102 located at the right edge of the frame 10 faces right, and the diversion trench 102 located at the lower edge of the frame 10 faces downward. As shown in fig. 3, a flange 202 is provided on the periphery of the lid seal 20, the flange 202 extends to a side close to the frame 10 (extends to the rear side as shown in fig. 1), and as shown in fig. 3 and 4, at least part of the flow guide groove 102 is located in an area surrounded by the flange 202. When rainwater and the like fall at the joint between the frame body 10 and the cover seal 20, due to the shielding effect of the flange 202, the rainwater cannot directly fall to the gap between the diversion trench 102 and the cover seal 20, but can directly fall into or flow into the diversion trench 102, and the diversion trench 102 can guide the rainwater to two sides of the frame body 10 perpendicular to the set direction, namely the left side and the right side as shown in fig. 1, so that the risk that the rainwater seeps downwards from the gap between the frame body 10 and the cover seal 20 can be reduced, and the risk that water enters the inside of the box body 100 of the inverter is reduced.

In some embodiments, the flange 202 is spaced apart from the frame 10 (as shown in fig. 5), or the flange 202 is in contact with the frame 10, which are within the scope of the present utility model. The flange 202 is spaced from the frame body 10 so that the cap 20 is less likely to be deformed by compression when the cap 20 is mounted.

According to some embodiments of the present utility model, as shown in fig. 5, a peripheral edge of at least one side of the frame 10 in a set direction is provided with a board 1021, the board 1021 includes a first plate 10211 and two second plates 10212, the two second plates 10212 are spaced apart in the set direction, for example, spaced apart in a front-to-rear direction as shown in fig. 1, one of the second plates 10212 is connected to the frame 10 at an edge away from the opening in a direction perpendicular to the set direction, and the first plate 10211 connects edges of the two second plates 10212 near the opening to define a flow guide groove 102 between the two second plates 10212. The diversion trench 102 (shown in fig. 6) formed by the structure has simple structure and strong practicability, and is convenient to process.

In some embodiments, the two second plates 10212 may be disposed parallel to each other or may be disposed at an angle to have a better water guiding effect.

In some embodiments, the height of the second plate 10212 connected to the frame 10 in the direction perpendicular to the first direction is greater than the height of the other second plate 10212 in the direction perpendicular to the second direction, so that the flange 202 may be flush with the outer edge of the frame 10, which is advantageous for ensuring the aesthetic appearance of the case 100 of the inverter of the present utility model.

According to some embodiments of the present utility model, the panel 1021 is integrally formed with the frame 10, so that the risk of water penetrating into the case 100 of the inverter from the gap between the panel 1021 and the frame 10 can be reduced.

According to some embodiments of the present utility model, the at least one cover seal 20 and the frame 10 are sealed by the seal 30, so that the risk of water entering the case 100 of the inverter can be further reduced.

In some embodiments, the seal 30 may be a seal ring. For example, the seal ring may be a sponge seal ring.

The heat sink 201 is provided with a weight reduction region, and the weight reduction region may be provided on the heat dissipation plate 2011, on the fin 2012, or on both the fin 2012 and the heat dissipation plate 2011.

In some embodiments, a portion of the weight-reducing region is provided on the heat sink 2011 in a region where the electronic device 200 with less heat dissipation is mounted.

In some embodiments, the weight-reducing area may be a groove, a through hole, a hollow structure, or the like, which is not particularly limited herein.

According to some embodiments of the utility model, the two covers 20 are a heat sink 201 and a cover plate 203, respectively. In this way, the overall weight of the inverter case 100 is light.

The second aspect of the utility model also proposes an inverter.
