Vortex tubes are compact refrigeration and cooling sources with cooling capacities ranging from 1000 – 2800 BTU/(323 – 1180 Watts). Vortex tube performance can be easily adjusted by changing the inlet air pressure, the cold air to exhaust ratio, or by changing the generator in the tube itself. Although typically used for cooling, vortex tubes can also be used in heating applications by simply directing the hot exhaust air to the application.

Vortex tube technology was invented by French physicist Georges Ranque in 1930 and developed for industrial use by Vortec in the 1960s. See how it works. Since then, vortex tubes have been widely used in cooling applications in machines, assembly lines, processes, and test and measurement.

Working principle of vortex tube

The SUNAIR vortex tube only inputs compressed air at a common pressure (6-10 Bar). Through the conversion of the vortex tube, cold air is generated at one end (the temperature drop can reach -46°C on the premise of dry air), and hot air (the temperature can reach -46°C on the premise of dry air) is generated at one end. 127°C). Flow rate from 0.06M3/min to 2.8 M3/min. Refrigeration capacity can reach 6000 Btu/hr. (1512 Kcal/hr.)

Industrial standard compressed air is injected into the vortex tube through the nozzle, and then rotates 90° in the direction of the vortex tube at a high speed of 1,000,000 RPM and flows to the hot end of the vortex tube. Part of the hot air flow flows out from the control valve at the hot end of the vortex tube, and the remaining air flow The reverse direction continues the cyclonic motion in the center of the external vortex. During this process, the internal air flow exchanges heat with the external air flow and becomes an ultra-low temperature cold air flow and flows out from the cold end of the vortex tube, while the external high-temperature hot air flow flows out from the vortex tube. The hot end flows out.
