VORTEX TUBE Russian patent published in 2009 - IPC F25B9/04 

FIELD: heating systems.

SUBSTANCE: invention is intended for developing a new vortex tube design. Vortex tube includes body with energy separation chamber on hot flow outlet side of which there located is deswirler, throttle device and cover, and on cold flow outlet side - diaphragm and nozzle inlet of separated gas. Deswirler is made in the form of one flat spiral located in the centre, and/or several flat spirals located on circles coaxial to vortex tube; those spirals are attached with their edges to the cover and installed so that winding of spiral from its periphery to centre coincides with gas flow rotation direction. Cover is equipped with through holes coaxial to each spiral of deswirler.

EFFECT: increasing operating efficiency of vortex tube at its being used for gas flow division into two flows with low and high temperatures respectively, more beneficial use of energy potential of flow swirled by means of nozzle flow inlet.
