Description

Technical Field

[0001] This utility model relates to the field of power device technology, specifically a power device module with double-sided heat dissipation. Background Technology

[0002] Power devices such as IGBTs (Insulated Gate Bipolar Transistors) and MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) generate a lot of heat when they are working. If the heat generated by the power devices cannot be dissipated in time, it will seriously affect the operation of the power devices and their surrounding circuit components.

[0003] However, existing power devices with dual-sided heat dissipation are still not ideal in use. This is because multiple fans are usually placed on both sides of the power device to achieve dual-sided heat dissipation. This structure increases the cost of fan assembly and is not economical. Moreover, the energy consumption generated by multiple fans is also very high. In order to solve the above problems, the inventor proposes a power device module with dual-sided heat dissipation.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The cooling is achieved through the fan body. The cooling air enters the functional box from the fan body and is first filtered by the dust filter plate. The filtered cooling air is then split by the air distribution plate, and the cooling air is blown away in two groups. The air guide plate then guides the cooling air into the ventilation slot to cool each module. The ingenious structure achieves double-sided heat dissipation, which is more economical and practical than using multiple fan bodies, and also reduces energy consumption.

[0012] 2. The function frame is fitted onto the power unit housing. Then, the connecting piece is rotated, and the shaft rotates on the fixed block to move the connecting piece.

[0020] An array of fixed blocks 23 are fixedly installed on the outer side of the power unit housing 1. A rotating shaft 24 is rotatably installed on the opposite end of each fixed block 23. A connecting piece 25 is fixedly connected to the outer side of each rotating shaft 24. A bolt 26 is threadedly installed on one end of each connecting piece 25. One end of the bolt 26 is threaded through the connecting piece 25 and threadedly installed on the inner side of the functional frame 18.

[0021] By adopting the above technical solution, the functional frame 18 is fitted onto the power unit housing 1, and then the connecting piece 25 is rotated. The rotating shaft 24 rotates on the fixed block 23 to cooperate with the movement of the connecting piece 25. Then, the bolt 26 is installed into the functional frame 18 to fix the functional frame 18. The bolt 26 is removed to make it easy to remove the functional frame 18, which in turn facilitates the maintenance of the components fan body 22 and dust filter plate 27 on the functional frame 18. The structure is simple and the operation is convenient.

[0022] The inner fixing clip of the functional frame 18 is equipped with a dust filter plate 27.

[0023] By adopting the above technical solution, the air drawn in by the fan body 22 is effectively filtered by setting the dust filter plate 27, thereby filtering out dust particles in the air and improving air quality, so as to prevent them from entering the power unit housing 1 and causing damage to various electrical components.

[0024] Each bolt 26 has a lever 28 fixedly installed on one end.

[0025] By adopting the above technical solution, the bolt 26 can be rotated by manually adjusting the rotation of the lever 28, thus facilitating the adjustment of the bolt 26 without a screwdriver.

[0028] An array of pads 30 are fixedly mounted on the bottom surface of the functional block 18.

[0029] By adopting the above technical solution, the contact area between the equipment and the ground is increased by setting the shim 30, thereby improving the support stability.

[0030] Working principle: First, the power cord is inserted into the electrical connector 16. Then, the circuit board 11 and the modules on the circuit board 11 are powered on and put into use. When the power semiconductor module 12, drive module 13, control module 14, protection module 15 and other modules continuously operate and generate a large amount of heat, the fan body 22 is immediately activated for air cooling. The cooling air enters the functional box 18 from the fan body 22. The cooling air is first filtered by the dust filter plate 27. The filtered cooling air is then split by the air distribution plate 20, and the cooling air is blown away in two groups. Then, the air guide plate 19 guides the cooling air to enter the circuit. The ventilation slot 17 provides heat dissipation for each module. The ingenious structure achieves double-sided heat dissipation, which is more economical and practical than using multiple fan bodies 22. Energy consumption is also reduced. The functional frame 18 is fitted onto the power unit housing 1. Then, the connecting piece 25 is rotated, and the rotating shaft 24 rotates on the fixed block 23 to move the connecting piece 25. The bolt 26 is then installed into the functional frame 18 to fix the functional frame 18. The bolt 26 can be removed to easily remove the functional frame 18, which facilitates the maintenance of the components fan body 22 and dust filter plate 27 on the functional frame 18. The structure is simple and the operation is convenient.
