Abstract
A consolidated duplex heat exchanger includes a first unit heat exchanger used for instance as a radiator, and a second unit heat exchanger employed for instance as a condenser for a car-cooler. The two unit heat exchangers are juxtaposed parallel with and close to each other, and united together by common corrugated fins each extending between cores of said unit heat exchangers. The corrugated fins are provided with cutouts intermediate the two unit heat exchangers parts so as to intercept undesirable heat conduction between said heat exchangers.
