Motor heat dissipation structure, air conditioner, and motor heat dissipation method

A motor heat dissipation structure, an air conditioner, and a motor heat dissipation method are proposed, wherein the motor heat dissipation structure includes: a motor; The refrigerant pipe is equipped with a first control valve, which is used to control the on-off of the refrigerant pipe; The second control valve is installed on the outlet branch of the four-way valve, parallel to the refrigerant pipe, to control the opening and closing of the outlet branch. When the opening of the first control valve is maximum and the opening of the second control valve is zero, the refrigerant pipe is opened, the outlet branch is disconnected, and the refrigerant flowing out of the four-way valve enters the refrigerant pipe from the first end and flows into the gas-liquid separator from the second end after passing through the motor. Through this technical solution, the refrigerant flowing out of the four-way valve can be used to cool the motor when the motor temperature is too high, saving the cost of cooling the motor, avoiding the waste of refrigerant, and saving the working cost of the air conditioner.
