Abstract

The disclosure provides a heat dissipation structure and a motor, including: a stator and a casing, the stator is assembled in the casing; the outer peripheral wall of the stator is provided with a first thread structure, the inner peripheral wall of the casing is provided with a second thread structure, and the first thread structure Matching with the second thread structure, the first thread structure is configured to increase the surface area of ​​the outer peripheral wall of the stator, and the second thread structure is configured to increase the surface area of ​​the inner peripheral wall of the casing. After the first thread structure cooperates with the second thread structure, the second thread structure A thread structure is in contact with the surface of the second thread structure. In the heat dissipation structure of the present disclosure, the stator and the casing cooperate through a screw structure, which can increase the contact area between the stator and the casing, improve the heat conduction between the stator and the casing, and reduce the temperature rise of the motor. At the same time, the cooperation of the thread structure is also conducive to improving the coaxiality of the stator and the rotor, and has a good effect on reducing the vibration and noise of the motor.

Description

technical field [0001] The disclosure belongs to the technical field of motors, and in particular relates to a heat dissipation structure and a motor. Background technique [0002] With the development of motor technology, the motor design area is miniaturized and lightweight. The power density of the motor is getting higher and higher, and the heat generated per unit volume is also increasing. The heat dissipation of the motor plays a vital role in the life of the motor. For every 10K increase in motor temperature, the life of the motor will be reduced by half. Contents of the invention [0003] Therefore, the technical problem to be solved in the present disclosure is how to improve the heat dissipation performance of the motor, so as to provide a heat dissipation structure and the motor. [0004] In order to solve the above problems, the present disclosure provides a heat dissipation structure, including: [0005] The stator and the casing, the stator is assembled in...
