Extruded coolant/refrigerant tank with separate headers

A combination radiator and condenser apparatus for a motor vehicle having a plurality of parallel tube passes for cooling high pressure refrigerant vapor in an air conditioning system for the motor vehicle and for cooling engine coolant having air centers bonded thereto for cooling fluid flow through said parallel tube passes comprising:

• said parallel tube passes each including a flow tube with aligned segments forming a refrigerant passage and a separate coolant passage;
• a pair of tanks,
• said tanks including a coolant space communicating with said coolant passages for flow of coolant therethrough, and a high pressure refrigerant space for communicating said refrigerant passages with a mechanical refrigerant system for directing refrigerant vapor through said passages for condensation;
• air center means connected to each of said aligned flow tube segments for conductively transferring heat from said coolant and said refrigerant vapor,
• each said tank comprising a unitary tank extrusion and two separate headers, said tank extrusion including a pair of side walls and a partition extending the length thereof to separate said coolant space from said high pressure refrigerant space, said separate headers having edges engaging said side walls and said partition to form said coolant space and said refrigerant space therebetween;
• and
• means for mechanically connecting said separate header at said edges to said tank extrusion.
