The first fin 11 is fixedly connected to the housing 0 by integral molding, and the second fin 12 is fixedly connected to the housing 0 by integral molding. A first fluid channel 111 is provided inside the first fin 11, and a second fluid channel 121 is provided inside the second fin 12. The first fluid channel 111 is a straight hole type, which is machined by a drilling process; the second fluid channel 121 is a straight hole type, which is machined by a drilling process.

[0035] Reference Figure 2 , Figure 5 to Figure 7 , a plurality of first fins 11 are provided, a plurality of second fins 12 are provided, the first fins 11 and the second fins 12 are arranged alternately, and the first fins 11 and the second fins 12 are both in the shape of straight strips.

When the heat-conducting fluid flows through the first fluid channel 111, the heat of the first fin 11 is transferred to the heat-conducting fluid and discharged together with the heat-conducting fluid, thereby cooling the first fin 11; when the heat-conducting fluid flows through the second fluid channel 121, the heat of the second fin 12 is transferred to the heat-conducting fluid and discharged together with the heat-conducting fluid, thereby cooling the second fin 12; after the temperatures of the first fin 11 and the second fin 12 are reduced, the heat inside the motor flows to the first fin 11 and the second fin 12 through the housing 0, thereby further cooling the entire motor.
