摘　　要：振荡管是入射气体与管内循环气进行能量交换的场所 ,是气波制冷机的一个重要组成部分。其结构形式的不同对管内流动产生很大的影响 ,进而影响气波制冷机的制冷性能。在分析了各种结构振荡管对气波制冷机性能的影响的基础上 ,着重分析了双开口振荡管的结构及制冷原理、管内的流动并通过实验研究了其对气波制冷机性能的影响。结果表明 ,采用双开口振荡管不仅能消除反射激波提高制冷效率 ,而且大大地优化了整机的结构 。The oscillation tube which is a very important part of the gas wave refrigerator is the place of energy exchange between the gas ripping into tube and the gas in tube. Its structure largely influences the performance. Based on analyzing influence of several structural oscillation tubes on performance of gas wave refrigerator, the structure, refrigeration principle and flow in oscillation tube with two-ports were analyzed. Its influences on performance of the refrigerator were experimented. The results show that oscillation tube with two-ports not only eliminates the reflected shock wave and improves the refrigeration efficiency but also largely optimizes the structure of the machine with volume being 10% of the former.
