ABSTRACT:
A combination radiator and condenser apparatus has a pair of extruded 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 an extruded tank with two compartments separated by an internal partition which extends the full height of the tank and each extruded tank further includes a slotted wall 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 of the extruded tanks; and a stop is provided in each of the tanks to position the flow tubes to space the inlets therein in a spaced relationship with the extruded tank walls; the extruded tubes can be of alternative designs including two separate extruded tubes, two separate fabricated tubes, or a combination of extruded or fabricated tubes rather than a common extrusion for connection respectively to the coolant chamber and the high pressure refrigerant chamber.
