Thanks to benkrasnow for the original Vortex tube and Hannes_v_d_B for the changes.
In the vortex tube, compressed air is brought into opposite spiral movements at high speed. This causes the air to split into a warm and cold air stream, leaving it warm on the long side and cold on the short side. The effect was discovered in 1928.
With 6 bar of compressed air I achieve a temperature difference of around 37°C, you can see how the difference increases with the pressure. With more pressure a larger difference is possible.
I inserted a 1/4" pipe thread (BSP) for the compressed air connection. I printed the vortex tube with line width 0.44 mm, layer height 0.16 mm, 3 walls, 5 top and bottom layer, infill 20% with PLA.
