Abstract
An outer plastic tube has water connections through the wall into an arcuate space defined by an O-ring spacer-gasket positioned between the wall and the perimeter margin of an inner cylinder rolled from a single-layer of sheet metal. A metal drainpipe with a removable bullet-shape at one end is forced through the cylinder to expand it and to thereby compress the gasket sealing the arcuate space. Thermal contact conductance is increased by the compressive force of water pressure. Water flow through the heat exchanger is both arcuate and turbulent to optimize heat transfer.
