[Abstract]:As the core component of the regenerative cryogenic refrigerator, the improvement of its efficiency is of great significance to the cryogenic refrigerator. The optimized design and experimental study of the regenerator of the 60 K Stirling refrigerator were carried out, and the optimum packing of the regenerator was obtained. By optimizing the structure of the cold end heat exchanger of the regenerator, the influence of its void ratio and local loss on the performance of the whole machine is discussed, and the optimum void ratio of the cold end heat exchanger is obtained, which effectively improves the refrigerating capacity and the temperature stability of the refrigerator. The refrigerating performance at 1.8W/60K@23 鈩，
