[0040] Embodiment 1

[0041] As Figure 1 、 Figure 2 shown, it is a preferred embodiment of the inverter heat dissipation device of the present utility model. Such an inverter heat dissipation device includes: a radiator 1, an inductor box 2, and a fan 3. Both the radiator 1 and the inductor box 2 are arranged on a box body 5, and the inductor box 2 is arranged on one side of the radiator 1, and the side wall of the inductor box 2 facing the radiator 1 has a heat dissipation part 21. The fan 3 is arranged on the radiator 1. The upper side of the fan 3 is the air inlet side, and the lower side is the blowing side. And a part of the blowing side is located above the radiator 1, and the rest is located above the heat dissipation part 21 of the inductor box 2. That is to say, when the fan 3 blows air, it can blow towards the radiator 1 and the heat dissipation part 21 of the inductor box 2 at the same time to cool and dissipate heat from the radiator 1 and the inductor box 2 together. The radiator 1 and the inductor box 2 are the main heat generating components. By blowing cold air from the fan 3 arranged on the radiator 1 towards the radiator 1 and the heat dissipation part 21 of the inductor box 2, the radiator 1 and the inductor box 2 can dissipate heat quickly. In this heat dissipation device, the air blown out by the fan 3 flows from the fan 3 to both ends of the radiator 1 and the inductor box 2. That is to say, the heat dissipation path is from the position of the fan 3 to both ends of the radiator 1 and the inductor box 2, and the heat dissipation path is shortened, and the heat dissipation effect is better, which can ensure uniform heat dissipation of the radiator 1 and the inductor box 2.

[0042] In other embodiments, the fan 3 can also be arranged on the inductor box 2, as long as it is ensured that the fan 3 can blow downward to perform air-cooled heat dissipation on the radiator 1 and the heat dissipation part 21 of the inductor box 2.

[0043] In other embodiments, the fan 3 can also be arranged on both the radiator 1 and the inductor box 2, that is, both ends of the fan 3 are respectively connected to the radiator 1 and the inductor box 2. This setting method also needs to ensure that the fan 3 can blow downward to perform air-cooled heat dissipation on the radiator 1 and the heat dissipation part 21 of the inductor box 2.

[0044] Further, the fan 3 is located in the middle of the radiator 1. In this way, the distances from the fan 3 to both ends of the radiator 1 and the inductor box 2 are the same, that is, the lengths of the heat dissipation paths on both sides are equal, which can ensure uniform heat dissipation of the radiator 1 and the inductor box 2.

[0045] Of course, in other embodiments, the position of the fan 3 may not be in the middle of the radiator 1 and can be offset to any end of the radiator 1.

[0046] The radiator 1 includes a plurality of first heat dissipation fins 111 arranged at intervals in the width direction of the inductor box 2, and there is a first air duct between two adjacent first heat dissipation fins 111. The cold air blown by the fan 3 circulates in the first air duct and exchanges heat with the high-temperature first heat dissipation fins 111 during the flow process to cool down the first heat dissipation fins 111, achieving the effect of cooling and heat dissipation.

[0047] Further, the heat dissipation device further includes an air duct plate 4 for arranging the fan 3. The air duct plate 4 is arranged on the radiator 1, the fan 3 is arranged on the air duct plate 4, and an air outlet is arranged at the position of the air duct plate 4 facing the fan 3, which is convenient for the fan 3 to blow air.

[0048] Specifically, a side plate 112 is arranged on the side of the radiator 1 away from the inductor box 2, and a card slot is arranged on the side of the side plate 112 away from the inductor box 2. A bending part is arranged on the side of the air duct plate 4 away from the inductor box 2, and the bending part is slidably clamped with the card slot. When installing or disassembling the fan 3, the air duct plate 4 can be slid into or out of the card slot along the card slot, and the disassembly and assembly are convenient.

[0049] In other embodiments, the card slot can also be opened on the side of the side plate 112 close to the inductor box 2 or on the top surface, and the bending shape and direction of the corresponding air duct plate 4 need to be changed adaptively to ensure slidable clamping with the card slot.

[0050] In other embodiments, the side plate 112 and the air duct plate 4 can also be detachably connected by other structures such as buckles.

[0051] In other embodiments, the side plate 112 and the air duct plate 4 can also be fixedly connected. For example, the side plate 112 and the air duct plate 4 can be processed into an integrally formed bent plate member.

[0052] Further, as Figure 4As shown in the figure, one side of the inductor box 2 is a heat dissipation part 21. The heat dissipation part 21 includes an air inlet groove and a heat sink group arranged on both sides of the air inlet groove. The heat sink group includes a plurality of second heat sinks 211 arranged at intervals along the height direction of the inductor box 2. There is a second air duct between adjacent second heat sinks 211. The air inlet groove is located directly below the fan 3, and the size of the air inlet groove gradually decreases from the end close to the fan 3 to the end far from the fan 3, that is, the shape of the air inlet groove is frustum-shaped, and the cross-sectional shape in the height direction of the inductor box 2 is trapezoidal, so as to facilitate guiding the cold air into each second air duct, with small air resistance and smooth flow.

[0053] The working process of the inverter heat dissipation device provided in this embodiment is described as follows:

[0054] Start the fan 3 to blow out cold air. Part of the cold air enters the first air duct in the radiator 1, and the rest of the cold air enters the second air duct in the heat dissipation part 21 of the inductor box 2. The flow path of the cold air, that is, the heat dissipation path, is as shown by the arrow in Figure 3 The cold air flows from the position of the fan 3 to both ends of the radiator 1 and the inductor box 2. During the flow process, the first heat sink 111 and the second heat sink 211 can be cooled and dissipated, and the heat dissipation path is short, which can uniformly dissipate heat from the radiator 1 and the inductor box 2, and the heat dissipation effect is good.

[0055] Embodiment 2

[0056] The difference between this embodiment and Embodiment 1 lies in the different structure of the heat dissipation part 21, and the rest of the structures are the same as those of the inverter heat dissipation device in the above embodiment, so they will not be described in detail.

[0057] As shown in Figure 5 In this embodiment, the heat dissipation part 21 includes a plurality of third heat sinks 212 arranged at intervals along the height direction of the inductor box 2. Each third heat sink 212 has an air inlet, and the size of the air inlet on the third heat sink 212 from the uppermost one to the lowermost one gradually decreases.

[0058] The shape of the third heat sink 212 is a thin sheet in the shape of "concave" after opening a long groove on a long strip plate. Compared with Embodiment 1, this structure of the heat dissipation part 21 has a larger heat dissipation area of the heat sink and fewer heat sinks, and is more time-saving and labor-saving during installation.

[0059] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
