[0002] Asynchronous motors, also known as induction motors, are a common type of AC motors that are widely used in a variety of industrial and commercial equipment. Asynchronous motors drive the rotor to move by generating a rotating magnetic field through induced current, without direct current to power the rotor. The main features include simple structure, high reliability, and low cost.

[0003] When the asynchronous motor is working, it will generate a lot of heat. If the generated heat cannot be dissipated in time, the asynchronous motor will easily be destroyed due to overheating. In the existing technology, the asynchronous motor is generally cooled by a cooling fan, but the cooling fan is also difficult to dissipate the heat generated by the asynchronous motor in time;

[0004] To this end, we propose a high-power asynchronous motor cooling device to solve the above problems. Utility Model Content
