Abstract
A combination radiator and condenser apparatus has a pair of tank and header assemblies adapted to be connected in both a coolant system for liquid cooled engine and a refrigerant system of an automobile air conditioning system. The assemblies each include a tank with two compartments separated by an internal partition which extends the full height of the tank. Each tank includes a slotted header for receiving the ends of a plurality of unitary extruded fluid flow tubes extending between each extruded tank and each of the unitary extruded fluid flow tubes have first and second passages therein connected respectively to the coolant chamber and the high pressure refrigerant chamber of each tank. Each tank includes a unitary tank extrusion and separate header assembly connected thereto. The tank extrusion includes a pair of side walls with the partition therebetween. A first embodiment of the header assembly includes two separate headers extending between the respective side wall and partition within grooves thereof. A second embodiment includes a single header extending between the side walls with a slot in the center to receive locking tabs extending from the partition.
