The change in air temperature along the axis of the expansion chamber in the zones of the nozzle inlet and the flow swirler in the direct-flow, counter-flow, three-flow and single-flow vortex tubes has been investigated. It has been established that in all cases, the cooling of air in the vortex tube occurs in the zone of the swirling device, and its heating - in the zone of unwinding of the flow. The change in air temperature in the axial zone along the length of the expansion chamber occurs due to heat exchange between the heating and cooling zones.
