Description

Technical Field

[0001] The present application relates to the field of motor cooling, and in particular to a motor cooling hard pipe connection structure. Background Art

[0002] With the acceleration of industrial scale and people's increasing attention to energy and environment, the single-unit capacity of drive motors is increasing, and motors are developing in the direction of miniaturization, lightness and high power density. However, as the single-unit capacity of the motor increases, its heat will become more serious, becoming an obstacle to the growth of the motor capacity. When the motor is running, it will produce losses, which are converted into heat energy and taken away by the motor cooling system, while increasing the temperature of various motor components. Excessive heating of the motor will cause the temperature rise to increase, which will directly affect the life of the insulation system used in the motor, and is related to the service life and safe operation of the motor. Therefore, in order to reduce the temperature rise of the motor, on the one hand, it is necessary to reasonably reduce the motor loss, and on the other hand, it is necessary to improve the cooling conditions so that the energy can be effectively dissipated as soon as possible.

[0003] Traditional motor cooling pipe fittings are generally fixed with nuts, which connect the motor pipeline and the cooling pipe to circulate the cooling medium. However, the car will vibrate during driving, and the nuts may become loose when the motor vibrates during operation, affecting the stability of the connection. Utility Model Content
