ABSTRACT:
A method and apparatus for exchanging heat between two fluid streams, wherein the two fluids are passed in heat exchange relationship with each other within a rotating heat exchanger mounted on a shaft. The heat exchanger comprises a rotating housing, with the heat transfer elements mounted within, so that one of the fluid streams is passed through areas near the housing periphery, and the other fluid stream is passed through areas that are inward nearer to the axis of rotation from the housing periphery. The heat exchanger elements are made of heat conductive material and form bellows like pockets for the heat exchange to take place. Various vanes or other means may be provided to reduce tangential movement of the fluids, and thermal insulation layers may also be provided to prevent undesirable heat transfer. Fluids passing through the heat exchanger may be either gases or liquids.
