Liquid-cooled motor heat dissipation structure

Abstract

The invention provides a liquid-cooled motor heat dissipation structure, which comprises a yoke part positioned in the middle. A front cover is arranged on one side of the yoke part, a rear cover is arranged on the other side, corresponding to the front cover, of the yoke part, two bearings are arranged in the liquid-cooled motor heat dissipation structure, the two bearings are respectively arranged in the front cover and the rear cover, a stator is arranged in the yoke part, a rotor is arranged in the stator, the rotor is supported by bearings in the front cover and the rear cover, two lining shells are arranged in the yoke part and are respectively adjacent to two sides of the stator, an end plate is arranged between the stator and the rotor, and the end plate is used for fixing the lining shells and the yoke part. The liquid-cooled motor heat dissipation structure is also provided with two cavities which are formed by closed spaces formed among the yoke part, the lining shell and the end plates, are positioned on two sides of the stator, and are used for storing cooling liquid.

Description

technical field [0001] The present invention relates to a motor, in particular to a liquid-cooled motor heat dissipation structure with cooling liquid stored in the motor. Background technique [0002] A motor converts electrical energy into mechanical energy and uses the generated mechanical energy to generate kinetic energy for driving vehicles or power equipment. [0003] The stator or rotor inside the motor is provided with a copper conductor coil, and the copper conductor has a certain resistance, so when the electric energy is converted into magnetic energy, part of the electric energy will be lost due to resistance and dissipated in the form of heat energy. When the heat energy is transferred to the enameled wire of the motor coil, it is easy to damage the outer polymer material of the enameled wire, resulting in short circuit damage to the coil, and ultimately damage to the motor. [0004] like figure 1 Shown is a perspective view of the prior art. A motor 20 incl...

AI Technical Summary

Problems solved by technology

A motor 20 includes a yoke 21 outside. At present, the motor 20 mainly relies on a plurality of fins 22 provided on the yoke 21 for heat dissipation. However, when the air field inside the motor 20 is not flowing, light is radiated by heat. The heat energy transmitted to the fins 22 on the yoke 21 for heat dissipation is limited, so the heat energy will be accumulated inside the motor 20 and it is not easy to dissipate heat, which may also cause damage to the motor 20
