Liquid-cooled cooling device and motor with the same

Abstract

The invention provides a liquid-cooled cooling device, which comprises a bottom plate and a cover plate of a water channel. The water channel where a cooling liquid flows is arranged on one side of the bottom plate of the water channel. A cooling liquid inlet and a cooling liquid outlet are arranged at both ends of the water channel. The cover plate is hermetically attached to one side where the water channel is arranged on the bottom plate of the water channel. The device can be flexibly loaded to a liquid-cooled cooling motor for strengthening the cooling effect or other non liquid-cooled cooling motors. The invention further provides a motor which is provided with the liquid-cooled cooling device. The motor comprises a housing or a stator iron core which is provided with at least a liquid-cooled cooling device in an attached manner. By increasing or decreasing the number of the liquid-cooled cooling devices, radiating function can be rapidly and flexibly adjusted to adapt to different work intensities or environments.

Description

technical field [0001] The invention relates to the field of motor cooling, in particular to a motor liquid cooling device. Background technique [0002] As the power source of the power drive device, the motor has been widely used in various fields at present. When the motor is running, it will generate a lot of heat, which needs to be dissipated in time. If the motor is working in a higher temperature environment, the heat generated is not easy to dissipate, which will cause the motor temperature to be too high or even exceed the motor’s tolerance range, affecting the performance of the motor. operating life. [0003] Liquid cooling is one of the most widely used cooling methods in the field of motor cooling at present. Its basic principle is to design water channels in the motor casing or motor shaft, and flow cooling water or coolant into the water channels to take away The heat generated by the motor prevents overheating from affecting the operation of the motor. For...

Problems solved by technology

Although this liquid cooling method is fast and efficient, it is not very flexible. Once the motor is manufactured, its heat dissipation efficiency cannot be changed. If the motor load increases or the temperature of the motor’s operating environment changes, it must be replaced with a more powerful cooling function. The motor seriously affects the working efficiency
