FIELD: cooling-heating devices.
SUBSTANCE: the method consists in acceleration of gas to the supersonic speed in a contoured nozzle, delivery of it to a tube and extraction of cold from the tube outer surface. The gas is subjected to overspeeding on spiral guides located inside the tube, then cold is extracted from the tube outer surface and then heat is extracted from the stagnant flow at the tube outlet. The cooling-heating device has a tube made of a heat-conducting material, and a contoured nozzle. A spindle-shaped insert is positioned in the tube axis, spiral guides are located on the insert surface.
EFFECT: enhanced efficiency.
