In order to improve the overall heat dissipation performance, an independent heat dissipation module 3 is mounted on the housing 21, the air duct in the heat dissipation module 3 is communicated with the housing 21, and the housing 21 is communicated with the chassis 1. In use, the fan 32 rotates to make the outside air enter the casing 1 through the first air inlet, and further take away the heat generated by the rotor and the stator inside the casing 1 directly.
