Abstract
An end fitting for a serpentine heat exchanger couples an inlet or outlet port to a pair of flat tubes comprising the heat exchanger core. The fitting comprises three laminated plates and a nipple coupled to an opening in the outermost of the plates. The inner plate is a header plate with the slots for receiving the flat tubing. A spacer plate interconnects the outer and inner plates and has an aperture shaped to couple the port to the slots for defining a fluid flow path. The plates are stamped from aluminum sheet stock clad with a brazing alloy. The plates are assembled and secured by a steel rivet and the nipple is attached. The parts are joined by brazing. The fitting can be brazed to the exchanger core at the same time.
