。 A cooling device comprising a blower unit having an inside air inlet and an outside air inlet and an intake door that selectively opens and closes both the inlets, and an evaporator of a vapor compression refrigeration cycle connected to the blower unit. In a vehicle air conditioner equipped with a unit, a super heat switch is provided on the downstream side of the evaporator of the refrigeration cycle to detect the degree of superheating of the refrigerant, and the intake door is opened to introduce outside air based on the detection signal of the super heat switch. An intake door control structure for a vehicle air conditioner, characterized in that an intake door drive control means for driving the intake door to a closed position is provided.
