[0002] The electric vehicle power conversion module is an important part of an electric vehicle. Its main function is to convert the direct current of the battery into alternating current to drive the motor. The power conversion module usually consists of power semiconductor devices, radiators, capacitors, reactors, etc. The performance of the power conversion module directly affects the power performance and cruising range of the electric vehicle. During the operation of the electric vehicle power conversion module, a large amount of heat is generated by the internal components. Therefore, it is necessary to quickly dissipate the internal heat through a cooling fan and a housing heat sink to prevent the internal components from being damaged due to overheating. In the existing electric vehicle power conversion module during use, dust will adhere to the heat sink on the outer wall of the electric vehicle power conversion module, which causes the heat dissipation gaps between the heat sinks to be blocked, resulting in poor air circulation and reduced heat dissipation efficiency, thus affecting the performance and lifespan of the electric vehicle power conversion module. For this reason, the utility model proposes a heat dissipation component for an electric vehicle power conversion module. Summary of the Utility Model

[0026] As Figure 2 and Figure 3 As shown in the figure, the cleaning component 4 includes a fixed bracket 401 fixedly arranged on the power conversion module 1. A motor 402 is fixedly installed on one side of the fixed bracket 401. The output end of the motor 402 is fixedly connected to a threaded rod 403 to facilitate driving the rotation of the threaded rod 403. The threaded rod 403 is rotatably arranged between the fixed brackets 401 through bearings. A threaded sleeve block 404 is threadedly sleeved on the outer wall of the threaded rod 403. A group of first transmission rods 405 are rotatably arranged on the outer wall of the threaded sleeve block 404 through bearings, facilitating the rotation of the first transmission rods 405 while moving. One end of the first transmission rod 405 is fixedly connected to a first sector gear 406. A connecting frame 407 is fixedly sleeved on the outer wall of the first transmission rod 405. A second transmission rod 408 is movably sleeved on the connecting frame 407. One end of the second transmission rod 408 is fixedly connected to a second sector gear 409. The second sector gear 409 is meshed and connected with the first sector gear 406. A brush roller 410 is fixedly sleeved on the outer wall of the second transmission rod 408 to facilitate driving the rotation of the brush roller 410.

[0027] Furthermore, the cleaning component 4 further includes a group of racks 411 fixedly arranged on the upper surface of the power conversion module 1. A gear 412 is fixedly sleeved on the outer wall of the first transmission rod 405. The gear 412 is meshed and connected with the rack 411, facilitating driving the rotation of the brush roller 410 during the horizontal movement of the first transmission rod 405, thereby cleaning the dust on the outer walls of the heat dissipation blocks 2.
