Efficient heat dissipation method for motor and motor applying efficient heat dissipation method

Abstract

The invention discloses an efficient heat dissipation method for a motor and a motor applying the efficient heat dissipation method. The heat dissipation method comprises the steps that: a cooling channel is formed in the periphery of a motor shell; a heat conduction channel in heat conduction connection with the cooling channel is arranged in a stator assembly; first gaps among windings are filled and packaged by a heat conduction filler; hollow grooves are formed in an insulating framework, and second gaps between the windings and a stator iron core are filled and packaged by a heat conduction filler through the hollow grooves, so that the heat conduction channel is formed in the stator assembly; and the heat of the windings is conducted to the cooling channel through the heat conductionchannel, and then the heat of the windings is discharged through the cooling channel. Through the specific heat conduction channel structure design, after the heat conduction channel structure is connected with the external cooling channel, the efficient heat dissipation effect on the motor is achieved, the power of the motor is effectively improved, and the efficiency of the motor is remarkablyimproved.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a high-efficiency heat dissipation method for motors, and also relates to a motor to which the high-efficiency heat dissipation method is applied. Background technique [0002] With the in-depth application and development of automation and intelligence in various fields, high-power motors are more and more widely used, such as in compressors and other fields. However, due to the high power of the motor and the inevitable loss of the motor winding and iron core during use, the motor is prone to generate a large amount of heat, and the heating of the motor will cause the aging of the winding insulation layer, power drop, and efficiency. In severe cases, it will cause the motor to burn out and shorten the service life of the motor. [0003] In order to realize the heat dissipation of the motor of the screw compressor, the current technology uses a fan installed inside t...

[0004] With further application, the applicant found that although CN111130256A provided a cooling channel on the motor casing to achieve a good cooling effect on the motor as a whole, the heat of the motor is generated by the loss of the motor winding and iron core, and the cooling channel does not It cannot actually improve the thermal conductivity inside the motor. Therefore, due to the internal heat conduction problem of the motor, there will still be hidden dangers of aging of the winding insulation layer, power drop, a
