Water cooling motor casing and water passage sealing structure of water cooling motor casing

Abstract

The invention provides a water cooling motor casing and a water passage sealing structure of the water cooling motor casing. A plurality of axial direct through holes are arranged on the side wall of the casing for forming water passages, the two ends of each direct through hole are sealed, communication holes are arranged between the direct through holes so that the water passages are connected, step grooves are arranged on the inner walls of the two side end parts of the water passages and are used for fixing and placing thin sheet aluminum strips, sealing glue is filled after the aluminum strips are placed, the aluminum strips are fixed, and in addition, the water passages are sealed. The process is simple, the production efficiency of a water cooling motor can be effectively improved, in addition, the sealing performance is high, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a water-cooled motor casing. Background technique [0002] For motors with large power, severe heat generation and poor heat dissipation environment, certain protection measures are generally required. In particular, the motor of electric / hybrid vehicles not only generates a lot of heat during its own work, but also the temperature of the equipment connected to the motor is very high, which transfers a large amount of heat to the motor, which further increases the temperature of the motor and seriously affects to the performance and efficiency of the motor. At present, cooling water jackets are generally used to cool down the motor, that is, to open a water channel on the outer wall of the motor and seal it through a sleeve, or to open a water channel on the motor casing, so that the water flows through the spiral or annular water channel to take away the motor. on the heat. ...

AI Technical Summary

Problems solved by technology

Since the water channel needs to be connected through the gasket and the end cap, a specific shape needs to be processed on the gasket and the end cap to match, the manufacturing process is complicated, the assembly is troublesome, and the waterproof sealing effect is not good
