The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a compressed gas into hot and cold streams. The gas emerging from the hot end can reach temperatures of 200 °C (390 °F), and the gas emerging from the cold end can reach −50 °C (−60 °F). [ 1 ]
Georges-Joseph Ranque (7 February 1898 – 15 January 1973) was the inventor of the Ranque-Hilsch vortex tube, which generates streams of hot and cold gas from a stream of compressed gas. Georges-Joseph Ranque was born in Ambérieu-en-Bugey , France in 1898. [ 1 ]
It can now be appreciated that the Hilsch tube is a fortuitous functional form which provides an internal flow configuration to generate an high velocity vortex, with a control valve to proportion the relative flows to achieve either maximum temperature drop ( an hundred degree F. or so drop from ambient ) or the Tube's maximum efficiency.

For transmitting tubes in this system, the second element starts with a dash, a sequentially assigned number, then an optional letter specifying cooling method. For phototubes and photomultipliers, the second element is a sequential number and then a letter code identifying vacuum or gas fill and the type of cathode.
