A RADIANT COOLER APPLIED IN COMPOUND-REFRIGERATING SYSTEM

摘要：

A two stage radiant cooler applied in a compound-refrigerating system (CRS) was developed. The CRS radiant cooler could provide 8.5 W cooling power at the temperature of 195 K and the refrigeration capacity of the cooler met the requirement of the compound-refrigerating system. In this paper, the processes of structure selection, thermal design, optimization design and thermal/vacuum test were described in detail. Mont Carlo method was applied in the calculation of radiant interchange factor and the calculation error was less than 0.4％. Through optimization design, the working performance of the optimized radiant cooler almost kept no change, though the structure dimensions decreased greatly. The optimization design method based on the non-scale heat theory and numerical calculation was proved to be effective.
