Abstract
A double heat exchanger for a vehicle air conditioner has a first radiator for cooling engine coolant, a second radiator for cooling electronic-parts coolant for cooling electronic parts of the vehicle and a condenser disposed at an upstream air side of the first and second radiators. The condenser has a condenser core and a cooler through which refrigerant discharged from the condenser core flows. The second radiator is disposed opposite the cooler so that air having passed through the cooler passes through the second radiator. Therefore, a difference between a temperature of air passing through the second radiator and a temperature of electronic-parts coolant flowing through the second radiator is increased, and electronic-parts coolant is sufficiently cooled. As a result, the electronic parts are sufficiently cooled without increasing a size of the second radiator.
