The location of the Duke of Teana blower is under the storage box. Remove the glove box of the co-pilot and the baffle, and you can see the blower, which blows the cold air above the evaporation box of the air conditioner or the hot air from the warm water tank into the car. The reason of abnormal sound of air-conditioner blower in automobile is that the blower blades beat against sundries to produce abnormal sound, and the airflow generated when the blower works blows light objects, and the air-conditioner filter element is dirty, resulting in excessive noise and abnormal sound. The vibration screw of the blower is loose, the blades of the automobile air conditioner are deformed, and the fan motor is damaged.

The blower operates eccentrically through the eccentric rotor in the cylinder, so that the volume between blades in the rotor slot changes to suck in, compress and spit out air. During operation, the lubrication is automatically sent to the drip nozzle by using the pressure difference of the blower, which can reduce friction and noise and prevent the gas in the cylinder from flowing back. This kind of fan is also called vane fan.
