VORTEX PIPE Russian patent published in 1995 - IPC

FIELD: cooling engineering. SUBSTANCE: vortex pipe has heat-exchanger-regenerator, ejector, turbulizing aerodynamic nozzle unit, and slide valve. The vortex pipe is additionally provided with heat- exchanger-regenerator 14 which abuts upon the hot end face of vortex chamber 5 for gas energy separation, the inner heat exchanging side of the chamber being an extension of the periphery part of chamber 5 and exhibited to circulating part of hot flow. Atmospheric air, which is fed with ejector 17 operated by circulating part of the hot flow, serves as a coolant for the heat- exchanger-regenerator. Energy separation of gas in the vortex pipe is carried out simultaneously with heat exchanging in the heat-exchanger-regenerator and turbulizing of working fluid in the chamber for gas energy separation. EFFECT: enhanced efficiency. 3 cl, 3 dwg
