Water-cooling motor shell

Abstract

A water-cooling motor shell comprises a shell and a water inlet and outlet structure. The shell is provided with several axial water channels along a circumference direction and the water channels are arranged along an axial direction of the shell. The water inlet and outlet structure is installed on the shell through a flange. The water inlet and outlet structure comprises the flange, a water inlet pipe and a water outlet pipe. The water inlet pipe, the water outlet pipe and the flange are integrated into one body. The flange is with a water blocking plate which separates the water inlet pipe and the water outlet pipe. A water inlet and outlet port flange is installed on the shell so that the water inlet pipe and the water outlet pipe are connected to one end of the water channels respectively. The water inlet pipe and the water outlet pipe are separated by the water blocking plate on the flange and are not directly connected. Water inlet and outlet port positions can be flexibly arranged according to a need and demands of the water inlet and outlet port positions of a whole vehicle are satisfied. Simultaneously, the water blocking plate of the flange is used to separate the water channels into two portions which are different to each other so that a dead water region is prevented, which is good for heat dissipation of a motor; the water inlet and outlet structure is designed to be reliable, processing and installation are convenient and maintenance is easy to achieve.

Description

[0001] technical field [0002] The invention relates to the electrical field, in particular to motor technology for electric vehicles, in particular to a water-cooled motor housing. Background technique [0003] Most of the driving motors for electric vehicles are water-cooled motors, and the water-cooled housing is usually used to dissipate heat from the motor stator. The straight water channel shell scheme extruded from aluminum alloy has the characteristics of low cost, wide adaptability, and no air shrinkage cavity, so it has been widely used. However, the position of the water inlet and outlet on this kind of housing is subject to many restrictions. According to the traditional arrangement method, since there can be no dead water area between the water inlet and outlet that will affect the heat dissipation of the motor, its position can only be arranged near a certain end of the housing. The two adjacent waterways cannot be adjusted flexibly according to the needs, wh...

However, the position of the water inlet and outlet on this kind of housing is subject to many restrictions. According to the traditional arrangement method, since there can be no dead water area between the water inlet and outlet that will affect the heat dissipation of the motor, its position can only be arranged near a certain end of the housing. The two adjacent waterways cannot be adjusted flexibly according to the needs, which often brings great trouble to the layout of the whole vehicle
