THERMOELECTRIC SEMICONDUCTOR HEAT EXCHANGER Russian patent published in 2000 - IPC

FIELD: refrigerators, air conditioners, and the like. SUBSTANCE: heat exchanger has tubes made of material possessing high heat-transfer properties and arranged coaxially with outer tube provided with radial longitudinal slits and inner one made in the form of polyhedron. Device also has thermoelectric modules assembled of thermal cells and electrically interconnected in series sections. First junctions of thermoelectric modules are placed on edges of inner tube over its entire length; second junctions arranged in radial slits of outer tube level with its surface are provided with longitudinal fins attached at their foot to outer tube surface. Power terminals of thermoelectric modules and air discharge pipe are brought out through ends of pressurized intertube space. Proposed design of heat exchanger makes it possible to dispense with environmentally harmful liquids such as freon. EFFECT: facilitated manufacture, improved operating reliability. 2 cl, 3 dwg
