Application of vortex gas-dynamic coolers in the rare gases extracting technologies

Vortex tubes are inferior it to expander efficiency, but they have a number of incontestable advantages, such as compactness, high reliability, multifunctionality. Despite these advantages, there are several examples of vortex tubes effective use in cryogenics. The problems accompanying to the creation of vortex coolers, designed for neon and heliu, producing units were discussed. The transition to low temperatures level is always accompanied with gas-dynamic devices miniaturization. At the same time? Most of the recommendations for vortex devices design refers to high-flow facilities that are powered by air with ambient temperatures. For this reason, known geometric relations aren't useful for vortex units with small diameters of the energy separation chamber (D). The scale factor effect in the diameter interval less than 10 mm has been studied experimentally. The advantages of low-temperature vortex tubes stepwise switching in the schemes of rare gas separators units were shown. The use of a technological pressure difference for feeding vortex devices was justified.
