[0038] like Figure 1 , Figure 4 and Figure 5 As shown, this embodiment further includes a heat dissipation fan assembly 6, and the heat dissipation fan assembly 6 is arranged between the heat sink 1 and the inductor 2. Further, as Figure 4 As shown, the radiator 1 described in this embodiment is provided with a avoidance notch 101, and the position of the avoidance notch 101 corresponds to the position of the cooling fan assembly 6, so as to increase the distance between the air outlet of the cooling fan assembly 6 and the fins of the radiator 1, and can effectively reduce the wind resistance of the air outlet, make the wind speed flow field more uniform, and enhance the heat dissipation effect.

[0039] like Figures 8 to 13 As shown, this embodiment further provides an inverter, including the heat dissipation assembly as described above, and also including a PCB circuit board 7 and a chassis assembly 8, wherein the heat dissipation assembly is installed in the chassis assembly 8, and the PCB circuit board 7 is arranged between the heat dissipation assembly and the chassis assembly 8.
