【摘要】 对斯特林制冷机用于制冷温区进行了探讨，提出一种复合型的低温制冷机型式─—脉管型斯特林制冷机，并从理论上分析了其制冷机理和性能，同时展开了实验研究，与单一的斯特林制冷机进行了性能对比，得出了有益的结果，脉管型斯特林制冷机用于２４５Ｋ以上温区较单一的斯特林制冷机具有优势。更多还原

【Abstract】 A new type of cryocooler Which is called Stirling refrigerator with a pulse tube was pre-sented.Its refrigeration mechanism and performance were theoretically analysed.Perfor-mance experiments were performed for both pure Stirling refrigerator and the Stirling refrig-erator with a pulse tube. The results show that the Stirling refrigerator with a pulse tube issuperior to pure Stirling one in temperature range 245K above.更多还原
