How cold can a vortex tube get?
Vortex tubes can produce: Temperatures from -50° to +260°F (-46° to +127°C) • Flow rates from 1 to 150 SCFM (28 to 4,248 SLPM) • Refrigeration up to 10,200 Btu/hr. (2,571 Kcal/hr.) Temperatures, flows and cooling power are adjustable over a wide range using the control valve on the hot end exhaust.
How efficient are vortex tubes?
Accordingly, the analysis of experimental data shows the maximum isentropic efficiency of the vortex tube enclosure cooling is 0.37 at the cold mass fraction of 0.45. Air temperature in the enclosure is about 13°C in average.
Do vortexes give off heat?
They produce a hot and a cold air flow. The cold air flow volume will be the majority of those two flows in most cases. So you could say you get more from a vortex tube in terms of energy output when it is used as a cooling device than as one for heating.
Which type of refrigerant is used in vortex tube?
With no moving parts, no electricity, and no refrigerant, a vortex tube can produce refrigeration up to 6,000 BTU/h (1,800 W) using only 100 scfm of filtered compressed air at 100 PSI (6.9 bar). A control valve in the hot air exhaust adjusts temperatures, flows and refrigeration over a wide range.
How does the inner core of the Rankine vortex work?
The inner core prevents the free surface from attaining an infinite slope at the center of rotation, while the outer region allows the vortex to approach hydrostatic conditions at infinity. Pijush K. Kundu, David R. Dowling, in Fluid Mechanics (Sixth Edition), 2016
Why do you need a vortex air cooler?
Vortex tubes convert compressed air into a stream of cold air. Use them to keep heat-sensitive electronic equipment cool with cold air. They have no moving parts for a long service life. Note: Air supply must be filtered to remove moisture and contaminants.
How does a LG vortex air cooler work?
Lg. Vortex tubes convert compressed air into a stream of cold air to keep electronics within enclosures from overheating while also keeping dust and other contaminants out. These vortex tubes chill compressed air by 50° F or more. They include a ducting kit to distribute cool air throughout the enclosure.
How does the vortex work in a turboexpander?
The lost energy is delivered to the vortex, which speeds its rotation. In a vortex tube, the cylindrical surrounding wall confines the flow at periphery and thus forces conversion of kinetic into internal energy, which produces hot air at the hot exit. Therefore, the vortex tube is a rotorless turboexpander.
