A through hole 44 is opened on the surface of the mounting bracket 2. When the cooling fan 42 rotates, the external airflow enters the interior of the mounting shell 1 through the air inlet 45 on both sides of the mounting shell 1. The airflow passes through the power conversion board 3, carries away the heat it generates, and enters the through hole 44. Finally, the airflow carrying heat is discharged to the outside of the mounting shell 1 through the exhaust hole 46, so that the heat on the surface of the power conversion board 3 can be quickly dissipated, avoiding excessive temperature and affecting service life. The heat dissipation holes 11 opened on the surface of the mounting bracket 2 increase the airflow passage, so that heat can be quickly discharged.

[0031] Please see Figure 1 , Figure 4 The filter assembly 5 includes a placement frame 51 installed inside the air inlet 45. The placement frame 51 has a filter screen 52 inside and a slot 53 inside. The filter screen 52 has inserts 54 connected to both sides and the inserts 54 are inserted into the slot 53.

[0032] In practical use: A placement frame 51 is installed inside the air inlet 45, and a filter screen 52 is installed inside the placement frame 51.

The umbrella-shaped claws 7 are inserted into the mounting holes 9.

[0034] In practical use: Positioning posts 6 are installed around the surface of the mounting bracket 2. Two symmetrical umbrella-shaped claws 7 are installed on the top of the positioning posts 6. The connection between the positioning posts 6 and the umbrella-shaped claws 7 forms the mounting position 8. When the power conversion board 3 is installed with the mounting bracket 2, the umbrella-shaped claws 7 are inserted into the mounting hole 9. The inner wall of the mounting hole 9 squeezes and contracts the two umbrella-shaped claws 7, so that the umbrella-shaped claws 7 are inserted into the mounting hole 9. At this time, the power conversion board 3 is located at the mounting position 8. At this time, the two umbrella-shaped claws 7 unfold, which plays a fixed and limiting role, and the installation and fixation of the power conversion board 3 is completed.

A heat dissipation fan 42 is fixedly installed inside the support frame 41. The surface of the installation support 2 is provided with a through hole 44. When the heat dissipation fan 42 rotates, external airflow enters the installation shell 1 through the air inlet holes 45 on both sides of the installation shell 1. The airflow carries away the heat generated by the power conversion board 3 and enters the through hole 44. Finally, the airflow with heat is discharged to the outside of the installation shell 1 through the air outlet hole 46, so that the heat on the surface of the power conversion board 3 can be quickly dissipated, avoiding the influence of high temperature on the service life. The heat dissipation holes 11 provided on the surface of the installation support 2 increase the airflow permeability, so that the heat can be quickly discharged. When the external airflow enters the installation shell 1, it can filter the gas after passing through the filter screen 52, so as to filter out the dust and fluff in the gas and avoid the accumulation of dust and fluff in the installation shell 1, which affects heat dissipation.
