Problems solved by technology

However, due to the high power density of the drive motor, the heat is more serious, and air cooling or water cooling is often used. Due to the small size of the drive motor, air cooling is limited by the small heat dissipation area, resulting in poor heat dissipation, and water cooling is used. The current method is the main measure. In the water cooling system, a one-way valve will be installed in the pipeline as a directional control device. However, since the opening pressure of the one-way valve is constant and cannot be adjusted, it cannot meet the requirements of various working conditions. For example, when the water pump starts , the back pressure of a certain section of the pipeline needs to be low during the start-up phase, and the back pressure is constant during normal operation

Abstract

The invention discloses a push force-adjustable flow one-way control device. The push force-adjustable flow one-way control device comprises a main pipe, a branch pipe, a throttling seat, a sealing head, a push rod, a spring, an end plate, a pull pressure sensor, a top plate, a servo motor, a lead screw, a feeding nut, a protection cover, a rotation seat, a water inlet pipe, a water outlet pipe, athermal spreader, a cooling annular groove and cooling fins. The device is simple in structure, the opening push force of the sealing head is adjustable, the device is applicable to different workingcondition demands, the sealing head and the main pipe can be cooled, the service lifetime is prolonged, and the reliability is improved; and meanwhile, a hot medium passing through the main pipe canbe cooled, and the comprehensive utilization rate of a cold medium is effectively improved.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a thrust adjustable flow one-way control device. 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 generation 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, and water cooling is used. The current method is the main measure. In the water cooling system, a one-way valve will be installed in the pipeline as a directional control device. However, since the opening pressure of the o...
