VORTEX PIPE Russian patent published in 2003 - IPC

FIELD: heat engineering. SUBSTANCE: vortex pipe has nozzle input, diaphragm with central body, cold flow discharge pipe and slit-type diffuser adapted for discharge of hot flow and provided with axial pipe for introducing of cooled flow, with internal diameter of axial pipe being smaller than diameter of opening in diaphragm. Diaphragm is positioned at inlet end of cold flow discharge pipe arranged coaxially in casing mounted on cold end of vortex flows interference pipe. Induced vortex flow separator arranged around diaphragm opening is made in the form of annular slot formed in diaphragm material. Cooled flow ejector on slit-type diffuser wall has sleeve with axial cooled flow inlet pipe and aerodynamic blades. Axial pipe is extending through sleeve bottom. Aerodynamic blades are arranged in cantilevered relation on sleeve bottom around pipe discharge opening and are made narrowing from base to end. Blade inlet edges are oriented in direction opposite to oncoming vortex flow. Nozzle inlet is defined by combined tangential nozzles and annular cavity having oval-shaped section. Nozzle inlet annular cavity is communicated with vortex flows interference pipe through annular axial channel defined by diaphragm side surface and pipe internal surface. Vortex pipe may be used in vehicle conditioners. EFFECT: increased efficiency in utilizing kinetic energy of free and induced vortex flows. 16 cl, 6 dwg
