The inlet nozzle is fixed at a tangent to the main tube which causes the entering air to acquire the vortical motion which gives the device its name. At one side of the inlet nozzle is a fixed flow restriction called the 'cold orifice,' and at the other of the main tube there is a variable flow restriction called the 'hot valve.' These names derived from the essence of the Vortex tube, namely, that the air leaving the tube through the orifice is colder than the entering air while the air leaving through the valve is hotter. The degree of heating and cooling depends upon the relative amount of the air leaving each end of the tube. The Vortex tube was first discovered by G. J. Ranque, 1931. The following several years, the research was performed, but it was given up until Hilsch rediscovered it. Hilsch had begun his investigation on the Vortex tube 1944 after reading Ranques paper, Interest in the Vortex tube has increased high, and many researches have been done untill now. Recently,
