The invention provides an electric vehicle controller water cooling system which comprises a water channel, a first gasket, a second gasket, a first end connector, a second end connector, a first connection pipe, a water pump, a second connection pipe, a heat dissipation system and a third connection pipe. The first gasket and the first end connector are sequentially arranged at one end of the water channel, and the second gasket and the second end connector are sequentially arranged on the end face of the water channel. Driving power pipes are fixed on the water channel, a temperature sensor is bonded to the outer surface of the water channel, the first connection pipe is connected with the second end connector and the water pump, the second connection pipe is connected with the water pump and the heat dissipation system, and the third connection pipe is connected with the heat dissipation system and the first end connector. The temperature sensor is used for sensing the temperature of the water channel, and a controller is used for measuring the temperature of the water channel and regulating the rotation speed of the water pump and the rotation speed of a fan according to the temperature of the water channel. Cooling water in the inner hollow cavity of the water channel absorbs heat in the water channel, and the water pump rotates to drive the cooling water to flow in the water cooling system so as to lower the temperatures of the driving power pipes.
Description
technical field [0001] The invention belongs to the fields of new energy vehicles and mechatronics, in particular to a device for cooling the heat generated by a driving power tube of an electric vehicle controller by using cooling water, in particular to a water cooling system for an electric vehicle controller. The device can use the water cooling system to cool the part of the driving power tube where the heat generated by the controller of the electric vehicle is the most serious. [0002] Background technique [0003] With the development of science and technology and the improvement of people's living standards, electric vehicles have become an indispensable means of transportation for people's lives and transportation. Due to the high current in the working process of high-power electric vehicles, the driving power tube is easy to generate heat. If the heat generated is not dissipated in time, the temperature of the electric vehicle controller will rise sharply, whic...
