叙述了直接用氢化物吸附氯气进行压缩的回热式低温制冷机可行性的研究。如果吸附压力特性大,就可直接驱动回热式低温制冷机,则分置式斯特林循环或维勒米尔循环的气体压缩腔可用气体吸附式压缩机代替。简化理论表明,通过增加传热面积,并使氢化物和壁材料的热量保持不变,可以在几秒钟内获得压力特性。我们发现用扁平毛细管贮存氢化物,适用于氢化物压力特性大的压缩系统,与气动控制膨胀机连接时,热压缩系统的实验结果表明,当氢化物容器的加热温度和冷却温度分别为90℃和20℃,而频率为0.5Hz时,可达到的最低温度为95K。
The feasibility of regenerating cryogenic refrigerator by directly hydride adsorption of chlorine gas is described. If the adsorption pressure characteristics, you can directly drive the regenerative cryogenic refrigerator, the split Stirling cycle or Villemir cycle gas compression chamber gas adsorption compressor can be replaced. Simplification theory shows that by increasing the heat transfer area and keeping the heat of the hydride and wall materials constant, pressure characteristics can be obtained in seconds. We found that the use of flat capillary storage of hydride for hydride pressure characteristics of the compression system, and pneumatic control expander connected to the experimental results of the thermal compression system shows that when the hydride vessel heating temperature and cooling temperature were 90 ℃ And 20 ℃, while the frequency of 0.5Hz, the lowest temperature reached 95K.
