Description

A water-cooled motor housing

technical field

The invention relates to the technical field of water-cooled motor preparation, in particular to a water-cooled motor casing.

Background technique

The main function of the motor is to generate driving torque. As a power source for electrical appliances or various machinery, the motor will rotate at high speed during operation to generate a large amount of heat. In order to enable the motor to run for a long time, it is necessary to keep the motor running The heat generated is discharged in time to prevent the motor from being damaged due to excessive temperature caused by the motor running for a long time.

The patent number CN201710619083.6 in the prior art provides a water-cooled motor casing with a water channel sealing structure, including a cylindrical water-cooled casing and front and rear end covers at both ends, the water-cooled casing It includes an outer shell and an inner shell, and the gap between the outer shell and the inner shell forms a water channel by arranging several isolation plates. The water-cooled motor housing proposed by the invention is integrally penetrated along the axial direction, and the structure is simple. In addition, when considering the sealing of the water passage of the housing, the invention designs a sealing groove at both ends of the housing, and adopts a sealing ring, which can be very good. It is stuck in the sealing groove to complete the water channel sealing. At the same time, it also cooperates with the end cover to form the entire motor seal, that is, two seals are completed with one sealing ring.

At the same time, in order to meet the cooling efficiency of the water channels, multiple water channels need to be set up to cool the motor at the same time. Therefore, the welding process of the water channels is very complicated, and the welding process is very complicated. Even the slightest gap will lead to water leakage in the water channel, which will eventually cause damage to the internal short circuit of the motor.
