ABSTRACT:
A heat exchanger having a hollow inner housing positioned within a hollow outer housing, each housing being incomplete about its periphery to provide a pair of spaced apart edges. Adjacent peripheral edges of the housings are connected together in sealed relationship along the entire length of the housings while maintaining the space between the peripheral edges of the same housing, and surfaces of the inner and outer housings opposite to the peripheral edges are secured together in sealed relationship so as to be readily bendable in hinging fashion to permit the spaced peripheral edges to be separated and positioned about an existing fluid carrying conduit. A pair of end closure caps are provided at each end connecting the inner and outer housings together and closing the ends to provide a pair of cavities between the two housings. Inlet and outlet tubes are provided to each cavity. The inner housing has a flange extending outwardly at each peripheral edge and fastening members are attached to the flanges to draw them together and tighten the inner housing against the conduit.
