Abstract
A heat exchanger for exchanging heat between a first fluid and a second fluid comprises a moving partition member for heat transmission between the first fluid and the second fluid, a housing partitioned by the moving partition member into a first chamber for passing the first fluid and a second chamber for passing the second fluid, and a power source for rotating the moving partition member.
Claims6
A heat exchanger for exchanging heat between a first fluid and a second fluid, the heat exchanger comprising:
- a moving partition member for heat transmission between the first fluid and the second fluid,
- a housing partitioned by the moving partition member into one chamber for passing the first fluid in a first direction and another chamber for passing the second fluid in a second direction substantially opposite from the first direction, and
- a power source for rotating the moving partition member, wherein at least the first fluid is compressible, further comprising means for adiabatically compressing the first fluid in the one chamber, wherein the compression means comprises an upstream centrifugal turbine provided at the upstream end of the one chamber for imparting a forward thrust of a prescribed magnitude to the first fluid for forcing it into the one chamber and a downstream centrifugal turbine provided at the downstream end of the one chamber for imparting a backward thrust of a prescribed magnitude smaller than the magnitude of the forward thrust to the first fluid for forcing it in the upstream direction.
