1. The working principle of the car blower.
The main working principle of the car blower is to control the temperature of the air in the car, or to ventilate the air in the car, or to purify the air. The driver turns on the blower of the car. If the temperature is selected to the lowest temperature, the vehicle will be externally circulated, which will cause the temperature of the car to rise, and the blower will work, thereby reducing the temperature of the car. If the driver chooses the internal circulation of the car, the blower will be used to export the high temperature in the car, thereby cooling the car.
2.The role of the car blower.
The blower of a car is actually mainly composed of a motor. Its function is to blow the cold air generated on the air conditioner evaporation box or the hot air generated from the car heater into the interior of the car, so as to reach the temperature of the car to the control effect. The external circulation of the car is to blow the natural wind outside the car into the car, while the internal circulation of the car is to blow the temperature out of the car, so the work of the car blower is also different when the external circulation and the internal circulation are used.
3. The performance of the car blower when it fails.
When the car blower fails, it will cause the air conditioner outlet in the car to produce no air, or there will be abnormal noises when the blower is required to work. And sometimes when the car blower fails, the air supply volume will be reduced, which will affect the cooling or heating effect in the car. When there is a problem with the car blower, it will affect the normal operation of the air conditioning system in the car. When the blower of the car fails, the owner needs to go to the 4S shop or a professional maintenance organization to repair the car.
