PCT No. PCT/RU92/00137 Sec. 371 Date Mar. 10, 1994 Sec. 102(e) Date Mar. 10, 1994 PCT Filed Jul. 10, 1992 PCT Pub. No. WO94/01727 PCT Pub. Date Jan. 20, 1994.A method for gas cooling with the use of a vortex tube into which the gas to be cooled is admitted through a scroll, where the gas is swirled and accelerated, and is expanded at the inlet of the vortex tube, then is divided into a peripheral part and an axial part, the peripheral part of the gas stream being discharged from the cooler along curvilinear pathways which are joined together with the pathway of motion of the gas stream over the tube walls, without formation of standing waves. A gas cooler comprises a scroll (1), an expansion chamber (2), and outlets for the peripheral and axial parts of the gas stream, wherein the peripheral part of the gas stream is discharged either through curvilinear ports (7) made in the wall of the expansion chamber, or through a second scroll (11). The gas which has passed through the second scroll, is joined with the axial part of the gas stream.
