Embodiment Construction
[0017] The technical solution of the present invention will be described in more detail below in conjunction with the accompanying drawings.
[0018] The main structure of this embodiment lies in the pulsating heat pipe cooling device arranged in the outer shell of the motor. The pulsating heat pipe mainly includes a space-distorted closed channel with multiple elbows. Cooling treatment is respectively implemented at one end of the channel, and the water tank of the pulsating heat pipe device is immersed Among them, the water tank is arranged with an inlet and outlet to realize the circulation and constant temperature of the water in the water tank. The other end is attached to the surface of the motor casing. In addition, the cross section of the closed passage can be designed as a circular cross section. The function of the invention is that the motor can be efficiently cooled, thereby replacing the existing motor with fan cooling structure and realizing low-noise operation...
