How long has the Vortex Tube been around?
The vortex tube was invented in 1933 by French physicist Georges J. Ranque and German physicist Rudolf Hilsch improved the design and published a widely read paper in 1947 on the device, which he called a Wirbelrohr (literally, whirl pipe). The Vortex Tube has been known as the “Hilsch Tube”, the “Ranque Vortex Tube”, the “Maxwells’s Demon, and the “Ranque-Hilsh Tube”. It’s a reliable, simple and low cost answer to various spot cooling problems within industrial plants.
