Vortex tube having at least two generators

Abstract

A vortex tube according to an embodiment of the present disclosure includes a cold and heat separation chamber; a cold air outlet provided at an end of the cold and heat separation chamber, a generator provided between the cold air outlet and the cold and heat separation chamber, a hot air outlet provided at another end of the cold and heat separation chamber and including a hot air adjusting valve, and an outer tube cover having a compressed air inlet and surrounding the cold and heat separation chamber at a predetermined gap while blocking the cold and heat separation chamber at an outside thereof, so that introduced compressed air can be supplied into the generator, wherein the compressed air flowing through the compressed air inlet generates rapid rotating wind by passing through the generator to be moved into the cold and heat separation chamber to separate cold and heat from each other.

1 . A vortex tube comprising:
 a cold and heat separation chamber;   a cold air outlet provided at an end of the cold and heat separation chamber;   a generator provided between the cold air outlet and the cold and heat separation chamber;   a hot air outlet provided at another end of the cold and heat separation chamber and including a hot air adjusting valve; and   an outer tube cover comprising a compressed air inlet and surrounding the cold and heat separation chamber at a predetermined gap while blocking the cold and heat separation chamber at an outside thereof, so that introduced compressed air can be supplied into the generator,   wherein the compressed air flowing through the compressed air inlet generates rapid rotating wind by passing through the generator to be moved into the cold and heat separation chamber to separate cold and heat from each other.   
     
     
         2 . The vortex tube of  claim 1 , wherein a counterflow prevention cap is inserted in the hot air outlet including the hot air adjusting valve. 
     
     
         3 . A vortex tube comprising:
 a cold and heat separation chamber;   a cold air outlet provided at an end of the cold and heat separation chamber;   a first generator, a sleeve, and a second generator provided between the cold air outlet and the cold and heat separation chamber;   a compressed air inlet provided at a portion close to the first generator and the second generator and configured to supply compressed air into the first generator and the second generator; and   a hot air outlet provided at another end of the cold and heat separation chamber and including a hot air adjusting valve,   wherein an outlet of the sleeve has a diameter larger than a diameter of an entrance of the cold air outlet and smaller than an inner diameter of each of the generators.   
     
     
         4 . The vortex tube of  claim 3 , wherein the sleeve is inclined such that an entrance of the sleeve has a diameter larger than the diameter of the outlet of the sleeve. 
     
     
         5 . The vortex tube of  claim 3 , wherein a diameter of an entrance of the sleeve coincides with the inner diameter of the first generator. 
     
     
         6 . The vortex tube of  claim 5 , wherein the diameter of the outlet of the sleeve satisfies the following equation.
   [diameter of entrance of cold air outlet+{(inner diameter of cold and heat separation chamber−diameter of entrance of cold air outlet)/2±(inner diameter of cold and heat separation chamber−diameter of entrance of cold air outlet)/4}]
   
     
     
         7 . The vortex tube of  claim 3 , further comprising:
 a third generator in addition to the second generator.   
     
     
         8 . The vortex tube of  claim 7 , further comprising:
 a second sleeve in which the third generator is provided, wherein a passage in the second sleeve is inclined such that an entrance of the second sleeve has a diameter larger than a diameter of an outlet thereof.
