Abstract
The drawings and description disclose a heat exchanger including two half circle shells, each having corrugated walls, with the half circle shells being welded together at their mating edges to form a full round shell. Prior to the welding operation, a perforated header is mounted in the half shells in the first corrugation adjacent each end thereof, and a plurality of perforated baffles are mounted within the half shells intermediate the headers in corrugations at alternate equally spaced intervals therein. The perforations in the headers and baffles are formed to be aligned, and a tube is mounted through each series of aligned openings to form a tube bundle within the half shells. The two half shells are welded together at their mating edges to form the full round shell, and the headers are brazed to the shell and the tube end portions brazed to the headers. Coolant inlet and outlet end caps are secured to the ends of the shell, and oil or other fluid inlet and outlet connectors are secured to the sides of the shell adjacent the respective ends thereof. Hence oil or other fluid is caused to flow around the tubes and the baffles to be cooled by coolant passing through the tubes.
