ABSTRACT:
A combination radiator and condenser apparatus for a motor vehicle has inlets and outlets adapted to be connected in both a coolant system for a liquid cooled engine and in a refrigerant system of an automobile air conditioning system. The apparatus includes a plurality of axially aligned fluid flow tubes having the same air centers and the tubes each extend between combination radiator and condenser tanks, in one embodiment the axially aligned fluid flow tubes are unitary, integral fluid flow tubes with a separate refrigerant vapor passage and a separate engine coolant passage therein. A method for simultaneously cooling engine coolant and refrigerant vapor in combined radiator and condenser apparatus for a motor vehicle includes the steps of directing vehicle inlet airstream through common air centers between the axially aligned refrigerant vapor tubes and vehicle coolant tubes.
