VORTEX TUBE Russian patent published in 2008 - IPC F25B9/04 

FIELD: physics; heating.

SUBSTANCE: vortex tube includes tangential or scroll inlet fitting, cylinder working chamber, hot gas inlet fitting, throttle and cold gas inlet fitting, is supplied by series cold and hot cylinders of working chamber. Cold cylinders represent ring closed loop with circulating cold coolant. Hot cylinders can represent ring closed loops with circulating hot coolant. Hot cylinders can be designed as rings made of heat-resistant electrical insulating material with internal ring cavity into which electrospiral with led-out terminals is inserted, and fixed from inside with thermocement. Hot cylinders can be designed as metal circular groove with attached electrospiral isolated from groove by ceramic scaly beads. Thus spiral terminals are connected on heat-resistant insulator, and groove is closed from outside with metal screens. Cold gas inlet fitting contains nozzle of external diameter (0.65...0.85)·D, where D is internal diameter of cylinder.

EFFECT: higher efficiency of power distribution due to increased temperature difference between hot and cold gas and reduced flow loss.
