| 摘要: |
| 本文综述了微小型焦耳-汤普逊（J-T）效应节流制冷器近年来的发展情况，从制冷器的结构型式演变以及理论研究两方面对现有技术和研究成果进行了总结，在分析有关文献的基础上对微小型J-T效应节流制冷器的发展方向做了进一步的展望。随着应用领域的拓展及加工工艺的进步，制冷器的结构型式越来越趋于小型化、多样化，借助微刻蚀技术制作的多级、多层、多通道微小型J-T节流效应制冷器具有很大的发展空间；在理论研究方面，由于微小型J-T节流制冷器的运行机理较复杂，目前的理论模型多是基于不同程度的假设，因此，对于微小型J-T效应节流制冷器的理论研究，不仅需建立并求解更切实际的理论模型，还需关注与及时应用相关的基础研究成果。 |

| Abstract: |
| The recent development of micro-sized Joule–Thomson (J-T) effect throttle cryocoolers is reviewed in this paper. The existing technology and research results are summarized from the theoretical research and structural evolution of the cryocooler. Based on the analysis of relevant studies, the development direction of the micro-sized J-T effect throttle cryocooler is further prospected. With the expansion of application fields and advances in processing technology, the structure of cryocoolers is becoming increasingly compact and diversified. Multi-stage, multi-layer, multi-channel, micro-sized J-T effect throttle cryocoolers fabricated by micro-etching technology have much room for development. In terms of theoretical research, the current theoretical models are mostly based on different assumptions and simplification because of the complicated operation mechanism of the micro-sized J-T throttle cryocooler. Therefore, for future theoretical research of J-T effect throttle cryocoolers, it is necessary to establish and solve more practical theoretical models, and basic research results need to be considered and applied in a timely manner. |
