VORTEX GAS COOLER Russian patent published in 1994 - IPC

FIELD: refrigerating engineering. SUBSTANCE: compressed air is fed to vortex tubes 1 through nozzle inlets 6. Pair opposed vortexes are formed by flow splitter 7 positioned in the vortex tubes. The gas is split in tubes into a cold near-the-axis flow and a heated peripheral flow which heat is utilized by cooling jacket 2 and flow splitter 7. Resonance tubes 12 located opposite and in the cross section of nozzle inlets 6 intensify the heat release process due to generating pulse flows in vortex tubes 1. EFFECT: intensified heat exchange. 2 dwg
