A cooling device for an automobile motor

Abstract

The invention discloses a heat dissipation device for an automobile motor, which comprises a motor casing with an open front end, a front cover connected to the front end of the motor casing, a shaft hole is arranged on the front cover, and a A heat dissipation housing with an open front end is connected to the end surface, and the front end surface of the heat dissipation housing is connected to the rear end surface of the front cover to form a seal. An annular cooling chamber for storing cooling liquid is formed between the heat dissipation housing and the motor housing. A plurality of heat dissipation pipes and a plurality of heat dissipation rings are provided in the ring-shaped heat dissipation cavity, and the heat dissipation pipes and heat dissipation rings are connected to each other, and a plurality of through holes are provided on the rear end surface of the heat dissipation housing. The rear end of the pipe extends to the outside of the heat dissipation casing through the through hole, the rear end of the heat dissipation pipe is opened, and an air circulation component and a coolant circulation component are respectively arranged on the rear end surface of the heat dissipation casing, which can pass through the heat dissipation pipe. The air circulation drives the heat in the ring-shaped heat dissipation cavity, and the heat dissipation ring increases the heating area and improves its heat dissipation efficiency.

Problems solved by technology

[0003] During the long-term use of traditional motors, the rotation of the motor rotor will generate a lot of heat. The existing motor shells often do not have the function of self-dissipating heat. A large amount of heat accumulation will have a large and serious impact on the performance of the motor. motor life

[0004] The existing heat dissipation of the motor is cooled by the coolant, but after a long time of work, after the temperature of the coolant rises, the heat dissipation still cannot be solved, and the existing heat dissipation structure cannot meet the use requirements
