Abstract

A double heat exchanger for a vehicle air conditioner combining a condenser and a radiator has a corrugated condenser fin and a corrugated radiator fin integrally formed and having the same fin pitch. Each of the condenser and radiator fins has plural upper folds, plural lower folds and plural wall portions each of which connects one of the upper folds and one of the lower folds next to each other. An inclination angle of each of the wall portions of the condenser fin is made different from that of each of the wall portions of the radiator fin. As a result, a height of the condenser fin becomes different from that of the radiator fin while maintaining a radius of curvature of each of the upper and lower folds of the condenser fin equal to that of each of the upper and lower folds of the radiator fin.
