Motor heat dissipation structure and air conditioner

Abstract

The invention discloses a motor heat dissipation structure and an air conditioner. The motor heat dissipation structure is used for the air conditioner, and comprises a motor and a condensed fluid recycler, wherein the motor is used for driving the air conditioner to work; a housing of the motor is provided with a condensing channel; the condensing channel is provided with a first condensed fluid inlet and a first condensed fluid outlet; the first condensed fluid outlet is communicated with a water drainage pipe of the air conditioner through a first conveying pipe; the condensed fluid recycler is used for storing condensed fluid of the air conditioner; the condensed fluid recycler is provided with a condensed fluid collection opening; the condensed fluid collection opening is communicated with a water drainage opening of the air conditioner through a second conveying pipe; the condensed fluid recycler is communicated with a first condensed fluid inlet through a third conveying pipe. According to the motor heat dissipation structure and the air conditioner, while normal operation of the air conditioner can be guaranteed, the temperature of the motor can be effectively reduced, so as to cool the motor; therefore, the operation performance of the motor is improved, and the service life of the motor is prolonged; in addition, by the adoption of the condensed fluid for cooling the motor, the waste condensed fluid is used, so that the utilization rate of resources is increased.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a motor cooling structure and an air conditioner. Background technique [0002] At present, with the improvement of people's living standards, air conditioners have become one of the necessary household appliances for thousands of households, and have been widely used. Existing air conditioners generally adopt different cooling fins on the surface of the motor, and the heat generated by the motor is dissipated into the air with the natural environment through the casing and the like by the air volume flowing through the surface. As the temperature of the external environment continues to worsen, the temperature rise requirements for the motor are getting higher and higher. [0003] However, as the indoor and outdoor temperature rises, the motor speed increases and the heat generation increases. If it is in this state for a long time, the working efficiency of the motor ...

Problems solved by technology

[0003] However, as the indoor and outdoor temperature rises, the motor speed increases and the heat generation increases. If it is in this state for a long time, the working efficiency of the motor will be reduced, and in severe cases, the motor may be burnt out. This forced convection The effect of heat exchange is relatively poor. When the air conditioner is running under some harsh conditions, the heat generated by the motor will continue to rise, which may eventually cause the motor to burn out. Speed ​​and other methods to reduce the heat generated by the motor during operation, which will cause the energy of the motor to not be used effectively, affect the normal operation of the air conditioner, and also reduce the safety and reliability of the air conditioner
