ABSTRACT:
A vehicle air conditioner includes an air conditioning case, a blower fan for blowing conditioned air into a passenger compartment, and an evaporator disposed in the air conditioning case. The air conditioning case has a cooling opening upstream from the evaporator, so that at least inside air is blown by the blower fan to vehicle electronic units through the cooling opening. Thus, heat radiation of the electronic units can be facilitated by air blown from the blower fan. Further, because at least inside air, without being cooled by the evaporator, is blown to the electronic units, the electronic units can be prevented from being excessively cooled. Accordingly, it can restrict the surface temperature of the electronic units from reducing less than a dew point, thereby effectively reducing condensed water on the electronic units.
