COOLING DEVICE OPERATION METHOD AND COOLING DEVICE

摘要

FIELD: cooling equipment, particularly that using vortex effect. ^ SUBSTANCE: method involves supplying direct flow in cold receiving means in several steps through serially connected vortex tubes. Each next vortex tube inlet is connected to cold nipple of previous vortex tube. Cold nipple of each next step is fastened to cold receiving means inlet. Energy separation chambers of vortex tubes are cooled with reverse flow leaving cold receiving means. The reverse flow successively passes through cooling cavities of energy separation chambers in reverse order so that cooling cavity of energy separation chamber at previous stage is cooled with reverse flow leaving cooling cavity of energy separation chamber of next stage. ^ EFFECT: simplified structure and increased efficiency. ^ 6 cl, 12 dwg
