Cooling water channel structure for motor casing

Abstract

The invention relates to a cooling water channel structure for a motor casing, comprising an inner motor casing and an outer motor casing, wherein the outer motor casing is hermetically sleeved on the inner motor casing so as to form a cooling channel between the inner motor casing and the outer motor casing, the outer motor casing is provided with a cooling liquid inlet and a cooling liquid outlet, the cooling liquid inlet is communicated with the cooling liquid outlet through the cooling channel, and preferably, the cooling channel is provided with a plurality of reinforcing ribs so as to guide the flow direction of a cooling liquid; and the cooling water channel structure for the motor casing further comprises a first sealing ring, a second sealing ring, a stopping and limiting part, a cooling liquid source and a power source, wherein the first sealing ring and the second sealing ring are used for sealing the outer motor casing and the inner motor casing, and the stopping and limiting part is arranged on the inner motor casing and used for stopping and limiting the outer motor casing. The cooling water channel structure for the motor casing in the invention has the characteristics of skillful structural design as well as simple and novel structure, can rapidly radiate heat for a motor so as to solve the problem on motor heat radiation, improve motor performance and finally improve the efficiency and prolong the service life of the motor, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of automobile structure, in particular to the technical field of electric motor cooling structure, in particular to a motor housing cooling water circuit structure. Background technique [0002] At present, in order to protect the living environment of human beings and save non-renewable resources, the energy consumption structure must be changed to avoid the energy crisis. Therefore, new energy vehicles play an important role in the current situation. [0003] As the heart of new energy vehicles, automotive motors are affected by comprehensive factors such as road conditions and vehicle loads, which make the working conditions of automotive motors more complicated than other motors. When they work, they will generate a lot of heat, which directly affects the motor. service life and operational reliability. The loss heat generated during the working process of the motor: ① The iron loss and copper loss of ...

Problems solved by technology

[0004] Therefore, the heat dissipation structure of the motor is particularly important in the automotive motor. If the heat loss is not discharged through the cooling structure, the temperature of the stator and rotor components of the motor will be too high, resulting in demagnetization of the rotor magnet and burnt of the stator wire package, affecting the motor. normal operation of
