Abstract

The invention relates to a novel cooling device for a motor, which comprises a water outlet, a casing outer sleeve, a casing inner sleeve, a water inlet, a hot air passage, a water passage partition plate, a spiral cooling water passage, an air inlet hole and an air outlet hole, the casing inner sleeve is provided with the hot air passage, the cooling water passage is provided a baffle plate, theaxial length of the casing outer sleeve is larger than that of the casing inner sleeve, and a gap between the spiral cooling water passage pipe body and the annular interlayer is filled with heat-conducting glue with good heat-conducting performance to form a heat-conducting glue layer. By adopting the cooling device, the temperature of each part in the motor can be effectively reduced, local overheating in the motor is avoided, and the power density of the motor is improved.

Description

technical field [0001] The invention relates to the field of high power density motors, and more specifically relates to a novel motor cooling device. Background technique [0002] With the development of motors in the direction of high power, high power density and small volume, the loss per unit volume of the motor is increasing, which leads to an increase in the temperature of the components in the motor, which directly affects the service life and reliability of the motor. Therefore, the motor The problem of cooling is getting more and more attention. [0003] At present, high power density motors are mainly cooled by casing water cooling devices. The casing water cooling device is generally composed of the casing inner sleeve and the casing outer casing. The interlayer formed between the casing inner casing and the casing outer casing is provided with heat dissipation ribs to improve heat dissipation. The motor stator core is in contact with the casing inner casing, an...
