Performance evaluation and experiment on a Miniature Joule-Thomson cooler

针对一种MMR制冷器开展了实验验证与性能分析,阐述了MMR的工作机理、并针对具体实验结果给予分析,讨论了影响制冷器性能的诸多因素,得到工质的工作压力对制冷器的性能影响显著。提出研制MMR制冷器原理型样机的设计与实施方案,对设计的新的节流制冷器进行了实验研究,对比分析了两种节流制冷器之间的性能差距原因。

Research on experiment verification and performance analysis of a miniature Joule-Thomson cooler（MMR） was conducted,working principle was described and experiment result was analyzed.It is found that the performance of MMR was affected by many factors,while the working pressure of refrigerant had significant effect on performance of the cooler.The design and implementing scheme of developing theoretical sample of MMR were put forward;the newly designed throttling refrigerator was studied by experiments and the cause of difference between two throttling refrigerators was analyzed.
