ABSTRACT:
A tubular heat exchanger, the core of which is comprised of two sets of U-shaped tubes facing in opposite directions. A header plate receives the ends of one set of tubes. Another, longitudinally spaced, header plate receives the ends of the other set of tubes, and the sets of tubes between the header plates are in a substantially interfitting relation. A manifolding means at the one header plate provides for flow of a first fluid at one temperature into the one ends of the one set of tubes and out the other ends thereof. Other manifolding means at the other header plate provides for similar flow of a second fluid at a different temperature through the other set of tubes. Intermediate their ends, the tubes of the different sets are in a nested, companion relation promoting a transfer of heat between the different flowing fluids. The core can be surrounded by a shell apertured for venting or draining of a leaked fluid or for flow of a third fluid over and around the assembled tubes.
