What is a Vortex Cooler / Vortex Tube or Spot Cooler??
A vortex tube, also known as a Ranque-Hilsch vortex tube, vortex tube, vortex cooler or spot cooler, uses compressed air and splits it into a directional warm and a cold air stream. Without using electricity, chemicals or moving parts.
This cold air stream, which is up to 40 ° C colder (depending on the compressed air inlet temperature), is very suitable for industrial cooling applications.
How does a Vortex tube work?
Compressed air flows through a compressed air connection [A] in the circular vortex tube chamber [B] of the vortex tube. The construction of the chamber causes the air to rotate extremely quickly, more than 1,000,000 revolutions per minute. and flows towards the end of the tube.
On the way, the air is heated by friction and at the end of the vortex tube comes out as hot air [C] through a valve [D].
Due to the high centrifugal force, part of the air stream bounces back and develops an internal, counter-directed second eddy current. This gives off heat to the external eddy current and comes out as cold air [E] at the other end of the vortex tube.
The air, which is up to 40 ° C colder, can now be used through an adjustable nozzle for selective and efficient cooling of a surface, a material, a tool or a component.
How to use a vortex tube?
What do you use a vortex cooler for?
As explained above, lvortex coolers create a targeted cold air flow. This even air flow is very effective for cleaning, drying or cooling, for example. Some possible applications are:
