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.

A method of manufacturing and assembling a vehicle dual radiator and condenser assembly having minimal structural and heat conductive interconnection, comprising, providing a pair of identical tandem header plate units, each tandem unit having a pair of elongated, regularly slotted header plates, one corresponding to said radiator and one to said condenser, and maintained in parallel relation on either side of a central plane by a pair of discrete, longitudinally separated webs occupying a small percentage of the total length of said header plates, thereby maintaining said header plate slots in coplanar pairs with a predetermined greatest edge to edge slot spacing and a predetermined least edge to edge slot spacing, providing four structurally separate, generally trough shaped tank units, one pair corresponding to said radiator and one pair corresponding to said condenser, each tank unit having an open side defined by a pair of parallel deformable flanges that are spaced apart by substantially the width of a respective one of said header plates, said flanges being continuous along their length but for a pair of spaced apart, discrete notches matching said header plate unit webs, providing a plurality of radiator tubes to fit into the slots in one of said header plates, providing a plurality of condenser tubes structurally separate from said radiator tubes to fit into the slots in the other of said header plates, providing a plurality of corrugated cooling fins to fit between adjacent pairs of said radiator tubes having a width substantially equal to said radiator tubes, providing a plurality of corrugated cooling fins to fit between adjacent pairs of said condenser tubes having a width substantially equal to said condenser tubes, placing said header plate webs into said notches to locate said header plates between said tank unit flanges and deforming said flanges over the edges of said header plates to produce two dual tanks, stacking one of said plurality of radiator or condenser tubes in a first tube layer with a tube spacing equal to said header slot spacing and with said cooling fins aligned with said tubes, inserting temporary spacers having a width equal to said least edge to edge slot spacing laterally across said first layer tubes, stacking the other of said plurality of radiator or condenser tubes in a second tube layer spaced from said first layer by said temporary spacer and also with a tube spacing equal to said header slot spacing, inserting cooling fins between adjacent tubes of said second layer until they abut said temporary spacers to complete said central core, tying said central core together and removing said temporary spacers, installing each of said dual tanks to said central core by inserting said header plate slots simultaneously over said radiator and condenser tube ends, and brazing said dual tanks and central core together to create said dual radiator and condenser assembly, the radiator and condenser portions of which are retained together only by said discrete webs, thereby reducing conductive heat cross flow.
