ABSTRACT:
A single inlet/outlet-tank U-shaped tube heat exchanger is disclosed comprising a tank having a header plate and a plurality of U-shaped tubes whose legs extend through and terminate with an open end at one side of the header plate. A first group of the tubes is arranged so that the two open ends of each of these tubes are located in one and the other of two outboard rows extending longitudinally of the header plate. A second group of the tubes with a smaller radius return bend is arranged in staggered pairs intermediate those in the first group and with their return bends parallel to each other and angled to those in the first group so that one open leg end of each of the tubes in the second group is located in one and the other of the outboard rows and the remaining open leg end of each of these tubes is located in a third and inboard row extending between the two outboard rows. A partition in the tank cooperates with the header plate to define an inlet chamber and an outlet chamber in the tank open respectively to the open tube ends in one and the other of the two outboard rows and also to alternate ones of the open tube ends in the inboard row whereby each of the tubes is connected to effect two-pass flow between said chambers.
