The liquid cooled motor shell includes sponge, crash plate, spring, telescopic rod, cover plate, liquid cooling pipe, return pipe, phase change energy storage plate, temperature control switch, refrigerator, liquid tank and liquid inlet pipe. The sponge is installed at the upper end of the collision plate, and the lower end of the collision plate is provided with a spring and a telescopic rod. The design can realize anti-collision. The liquid cooling pipe is arranged inside the cover plate. The upper part of the right end of the cover plate is equipped with a return pipe. The return pipe passes through the right end of the cover plate and is connected with the liquid cooling pipe. The return pipe is installed at the upper end of the phase change energy storage plate. The phase change energy storage plate is installed at the upper end of the liquid tank. The front end of the liquid tank is equipped with a temperature control switch and a refrigerator. The lower end of the liquid tank is connected with a liquid inlet pipe. The liquid inlet pipe is installed at the lower part of the right end of the cover, The liquid inlet pipe passes through the right end of the cover plate and is connected with the liquid cooling pipe. This design improves the cooling effect.
The cooling structure of the liquid cooled motor shell is simple and the processing is convenient; The coolant directly exchanges heat with the stator, which can fully take away the heat generated by the motor, and the heat exchange is sufficient. The utility model solves the problems of complicated structure of the cooling device and insufficient heat exchange between the cooling water and the motor in the prior art.
