Abstract
A heat exchanger has first and second flow passages with a communication passage therebetween. An inlet/outlet opening in a wall of the first passage receives a one-piece inlet/outlet fitting having an inner tube and an outer ring connected by webs, the tube and ring defining inner and outer flow passages in direct flow communication with the first and second flow passages, respectively. A first end of the tube and an outer surface of the ring are provided with resilient sealing members for sealing within a bore of a coolant manifold. The ring has a planar sealing surface which is sealed to the wall of the first passage, and the second end of the inner tube extends through the first fluid flow passage and is sealed inside the communication passage. Lateral adjustment of the fitting within the inlet/outlet opening compensates for stack-up tolerance variation in the heat exchanger.
