The Boost inductor 7 is placed within the mounting hole positions 22.

[0033] As Figure 4 shown, the air guide plate 3 includes a vertical baffle 31, an inclined baffle 32, a horizontal bottom plate 33, and a horizontal top plate 34. The inclined baffles 32 are provided on the left and right sides of the vertical baffle 31 to ensure a certain distance between the inverter inductor 8 and the side parts of the wind shield 1 and the radiator 5, which is helpful for the self-cooling of the inverter inductor 8.

It is placed on the radiator cover plate 6, and the bottom of the heat dissipation fins contacts the radiator cover plate 6 to limit its vertical downward displacement. Grooves 4 are opened on both sides of the top of the radiator 5, which cooperate with the 90° bent edges on both sides of the top of the radiator cover plate 6 to play a limiting role and limit the movement of the radiator 5 in other directions.

[0037] As Figure 5 shown, an inclined edge stop 63 is provided on the radiator cover plate 6. Multiple mounting holes are provided at the bottom of the inclined edge stop 63. By screwing bolts into the mounting holes, the radiator cover plate 6 is connected and fixed to the wind shield 1.

[0042] Step 3: Assemble the external component 100 with the cabinet body 200: Assemble the external component 100 with the cabinet body 200 as a whole. After the assembly is completed, remove the bolt connecting the inductor mounting component 2 and the windshield 1, and take out the inductor mounting component 2.
