How Do Vortex Tubes Work?
Compressed air is injected circumferentially into the tube at sonic speed and creates a cyclone (Vortex) spinning at a million revolutions per minute. Part of the air is forced to spin inward to the center hole and travels up the long tube where a valve turns the spinning column (Vortex) of air inside itself. The inside column of air gives up its heat to the outside column. The cold air is directed out the cold end of the Vortex Tube and the hot air is exhausted out of the other end of the Vortex Tube.
