An automotive dual radiator and condenser assembly with optimized structural and thermal capabilities. The two halves or layers of the dual assembly are interconnected by a pair of widely spaced, narrow webs, which webs interconnect two halves of a slotted tandem header plate unit. The webs, though small, are sufficient to maintain all components of the whole assembly properly and rigidly spaced at all times, during assembly, during brazing, and during and after installation. The two webs also represent the only significant direct heat conduction path between the radiator and condenser, so that thermal efficiency is comparable to a pair of non connected units.
