Problems solved by technology

[0003] The invention aims to solve the problem that the working medium cannot quickly return to the heat-absorbing end when cooling the motor rotor with a heat-conducting tube, and the cooling effect of the motor rotor is poor. It provides a cooling structure for the motor rotor using a heat-conducting tube, which can effectively avoid Influence of Rotor High-speed Rotation on Cooling Efficiency of Heat Transfer Tube

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 As shown, an embedded motor rotor cooling structure is used to cool the motor rotor, including a rotor 1, a motor shaft 11 for output torque on the rotor is provided with a coaxial blind hole 12 at one end located in the motor housing, Then insert the heat-absorbing end 21 of a heat-conducting pipe 2 into the blind hole, while the heat-dissipating end 22 on the other side of the heat-conducting pipe is exposed outside the motor shaft. The heat generated during work is dissipated through the heat pipe. In order to make the working medium in the heat transfer tube smoothly flow back from the heat dissipation end to the heat absorption end when the rotor rotates at high speed, the inner diameter of the heat transfer tube gradually increases from the end face of the heat dissipation end to the heat absorption end, that is t...

Abstract

The invention discloses an embedded motor rotor cooling structure, which includes a rotor, a coaxial blind hole is arranged at one end of the motor shaft on the rotor located in the motor housing, and a heat-absorbing end of a heat-conducting pipe is plugged into the blind hole. The inner diameter of the heat pipe increases gradually from the end surface of the heat dissipation end to the heat absorption end, and the inner wall of the heat absorption end of the heat pipe is provided with a sintered layer. The invention can effectively avoid the influence of the high-speed rotation of the rotor on the cooling efficiency of the heat-conducting pipe, so that the motor has a reliable cooling effect and at the same time facilitates its processing and manufacturing.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an embedded motor rotor cooling structure. Background technique [0002] The motor will generate heat when it is working, and it usually dissipates heat through the casing, or installs blades on the rotor to suck the air outside the casing into the casing, and then achieve the purpose of cooling. However, the above cooling methods have low cooling efficiency, and Noise problem. With the advancement of technology, people realize the cooling of the motor by arranging heat pipes that can conduct heat quickly on the motor. For example, a "motor cooled by heat pipe cooling method" disclosed in Chinese patent literature, the publication number is CN102751803A, the motor uses heat pipes to directly transfer the heat emitted by the motor heat source to cool the motor, including the stator and rotor , armature winding and two sets of independent heat pipe cooling groups, which can be use...
