ABSTRACT OF THE DISCLOSURE A keel cooler type heat exchanger is disclosed which is mounted on the exterior of the hull of a vessel or the like. The hull is curved in the direction of the length of the heat exchanger. The heat exchanger includes a pair of spaced headers secured to the hull and helically fluted tubes connected between the headers and curved in the direction of their length to substantially match the curvature of the hull. One or more intermediate tube supports are located between the headers. The helically fluted tube is laterally bendable with less stress than corresponding non- helically fluted tubes. The headers include separable members having cooperating tube and gripping portions formed along the interface therebetween. Bolt fasteners extend between the lowermost header member and a mounting plate. Separate fasteners separately and temporarily secure the inner member against the mounting plate and intermediate members against the inner member to facilitate the assembly and disassembly of the system.
