Apparatus for recovering waste heat from exhaust gas flowing through an exhaust pipe
An apparatus for recovering waste heat from a hot exhaust pipe and utilizing the heat to warm water passing through the apparatus, which comprises a plurality of thermal conduction members each longitudinally positioned in contact with said exhaust pipe, the plurality of conduction members being arranged circumferentially about the exhaust pipe, each of the thermal conduction members having a surface which is concavely arcuate in cross-section and of substantially the same curvature as that of the exhaust pipe and in contact engagement therewith. The thermal conduction members each have a longitudinal channel with a bottom of arcuate cross-section and a pair of spaced-apart longitudinally extending fins. A water pipe is positioned in the bottom of the channel of substantially the same arcuate cross-section as the bottom surface of the channel. The fins are bent or crimped over the pipe and placed in contact engagement with surface of the pipe. A plurality of u-shaped pipes each connect the ends of adjacent water pipe cooperating to provide a continuous water conduit having means at one end adapted to be connected to a water source, and having outlet means at the other end connected to the water inlet of an apparatus such as a water heater.
