Abstract
A recuperator for heat exchange between two flow media of dissimilar temperatures is formed by a housing containing the flow of a first of the two flow media and a plurality of essentially parallel slidably supported tubes containing the flow of the second flow medium. The tubes are made of a highly heat resistant material, such as ceramic material, and are biased at one end by an expansion pressure device that acts upon flow deflection connectors at the one end of the tubes. In one preferred embodiment, the expansion pressure means utilizes spring force, while in other preferred embodiments, the expansion pressure device uses a compressible medium for applying the biasing force.
