High-efficiency heat-dissipating water-cooled motor

Abstract

The invention discloses a high-efficiency heat-dissipating water-cooled motor, comprising a motor body, a first rotating shaft, an inner casing, an outer casing, an end cover, a support base, a firstgear, a fixing groove, a transition mechanism, a first bearing, a combined cam mechanism, an outer baffle, an inner baffle, a water pumping mechanism, a ring gear, a cooler, a water outlet distribution mechanism and a pressure regulation mechanism. The device is simple in structure and reliable in sealing, cooling liquid can fill a cavity between the inner casing and the outer casing, so that thecooling liquid can be in full contact with the cooler to perform efficient and uniform cooling, and moreover, the sequential liquid distribution can be realized, the heat dissipation effect and efficiency can be effectively improved, the process of separately setting a pump and a pump control system is not required, and the motor is stable in transmission and good in reliability; and meanwhile, the cooling capacity can be improved with the increase of the rotating speed, and the requirements of use under different working conditions can be met.

Description

technical field [0001] The invention relates to a motor, in particular to a high-efficiency heat dissipation water-cooled motor. Background technique [0002] Drive motors are one of the three core components of new energy vehicles. Compared with traditional industrial motors, drive motors for new energy vehicles have higher technical requirements. Like ordinary motors, new energy drive motors are mainly composed of three parts: stator, rotor, and mechanical structure. However, due to the high power density of the driving motor, the heat generation is more serious, and air cooling or water cooling is often used. Due to the small size of the driving motor, air cooling is limited by the small heat dissipation area, resulting in poor heat dissipation, and water cooling is used. It is often necessary to set up an independent water supply system and its control system, which leads to an increase in the complexity of the system. At the same time, the existing water-cooling design...

However, due to the high power density of the drive motor, the heat is more serious, and air cooling or water cooling is often used. Due to the small size of the drive motor, air cooling is limited by the small heat dissipation area, resulting in poor heat dissipation, and water cooling is used. It is often necessary to set up an independent water supply system and its control system, which leads to an increase in the complexity of the system. At the same time, the existing water-cooling design scheme often directly installs a water-cooling ring pipe or an annular water tank on the motor casing, which is prone to local uneven heat dissipation. problems, resulting in poor heat dissipation
