Abstract

The invention discloses a uniformly cooled motor shell. The uniformly cooled motor shell comprises an inner shell, an outer shell, a water distribution block, a water inlet pipe, a cooler, an outlet water distribution mechanism, a water outlet pipe, a pressure regulating mechanism and an end cover. In order to improve the uniformity of the distribution of coolant between the inner shell and the outer shell, the servo drive mechanism works to drive a push rod being fixedly connected with a tension pressure sensor to moved upwards, thereby changing the compression degree of a first spring, so that the coolant cannot easily separate the sealing head from a throttle seat; the coolant can reach any place of a cavity between the inner shell and the outer shell to exchange heat sufficiently withthe cooler; the utilization ratio of the coolant is increased effectively; and the heat dissipation effect is improved. The device is simple in structure, and the coolant can fill the cavity between the inner shell and the outer shell, so that the coolant can be fully contacted with the cooler for efficient and uniform cooling. At the same time, the utilization ratio of the coolant is high, and the cooling effect is good.

Description

technical field [0001] The invention relates to a motor, in particular to a uniformly cooled motor casing. Background technique [0002] Drive motors are one of the three core components of new energy vehicles. Compared with traditional industrial motors, drive motors for new energy vehicles have higher technical requirements. Like ordinary motors, new energy drive motors are mainly composed of three parts: stator, rotor, and mechanical structure. However, due to the high power density of the driving motor, the heat is more serious, and air cooling or water cooling is often used. Due to the small size of the driving motor, air cooling is limited by the small heat dissipation area, resulting in poor heat dissipation. Therefore, it is often used Water-cooling design, due to the existing water-cooling design scheme, the water-cooling ring pipe or ring water tank is often directly installed on the motor casing, and the coolant is directly pumped into the water-cooling ring pipe...
