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 chambers separated by an internal partition which extends the full height of the tank. 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. Each of the unitary extruded fluid flow tubes has first and second passages therein connected respectively to the coolant chamber and the high pressure refrigerant chamber of each of the extruded tanks. An open-sided gap or channel extends within the partition and the length of the tank for reducing heat conduction between the coolant and refrigerant. The channel is open through a longitudinal wall of the extruded tank.
