BLOWER UNIT OF AIR CONDITIONER FOR VEHICLE

摘要

Disclosed is an air blast device of an air conditioner for a vehicle, which prevents a resistor from being damaged due to foreign substances such as water flowing into a case of an air blower and facilitating cooling of the resistor, wherein the air blast device of the air conditioner for a vehicle has an improved structure in which ventilation resistance by the resistor is minimized. The air blast device of the air conditioner for a vehicle comprises: an air blower case having an internal air inlet and an external air inlet; a blower wheel installed in a lower part of the internal air inlet and the external air inlet to be able to rotate by a blower motor; and a resistor including a circuit board and a terminal unit. The resistor is installed in a lower side of the blower wheel to be inclined in the direction of air flow. The air blast device prevents the terminal unit of the resistor from being damaged and corroded due to water flowing into the air blast device. The air blast device facilitates cooling of the resistor and minimizes a loss in pressure by reducing ventilation resistance.
