Abstract
A tube and center heat exchanger has headers formed of three flat plates stacked and bonded together. One plate has apertures for receiving the tube ends, the second plate is a spacer and has partitions defining passages for fluid flow from one tube to another, and the third plate is an end cap to enclose the passages and may include inlet and/or outlet ports. The flat plates are stamped from flat sheet stock of braze clad aluminum, the necessary perforations are stamped out and the plates are stacked and riveted into header subassemblies. The tube and center elements are assembled and the tube ends are inserted into the header subassemblies. The whole condenser is brazed to form the bonding between the plates as well as the other elements.
