Since the guide pipes 102 are arranged on both sides of the placement groove 5 and are distributed in a rectangular shape, the nozzle 3 can simultaneously blow air to the side wall of the motor controller body 1 to take away the heat, thereby improving the timeliness of heat dissipation.

[0024] Reference Figure 1 and Figure 3A mounting groove 7 is provided inside the mounting seat 2 for connecting the top of the guide plate 10 with the placement groove 5. A heat conducting plate 9 is provided on the top of the guide plate 10, which is placed inside the mounting groove 7 and in contact with the lower side of the inner wall of the motor controller body 1. A connecting groove 11 is provided on the top of the guide plate 10 for connecting the heat conducting plate 9 with the guide groove 101. This design connects the heat conducting plate 9 with the guide groove 101 by using the connecting groove 11, so that the heat at the bottom of the motor controller body 1 is sent to the inside of the guide groove 101 under the action of the heat conducting plate 9. Under the action of the wind generated by the fan 6 inside the guide groove 101, the heat is sent out from the guide pipe 102 and the nozzle 3, so as to facilitate the heat dissipation of the bottom of the motor controller body 1, further enhance the heat dissipation effect of the motor controller body 1, and improve the timeliness of heat dissipation.
