Abstract
The multi-pass heat exchanger comprises an open-ended shell for receiving a first fluid and at least one tube bank disposed in the shell and connected to pass a second fluid in indirect heat transfer with the first fluid. The tube bank may comprise one or more conduits each of which are of polygonal configuration in cross-section and have spaced rows of fins extending from the large sized surfaces of the conduits. Each of the conduits is formed into a flattened helical configuration consisting of substantially straight portions so arranged that alternate straight portions extend in substantial parallelism and having return bend portions interconnecting end-to-end next adjacent straight portions so that series flow of second fluid is provided through the straight portions. The tube bank is positioned in the shell with the small sized surfaces extending in planes generally normal to the longitudinal axis of the shell so that the first fluid flows successively past the straight portions and thereby in indirect heat transfer with the second fluid flowing through the conduits.
