【摘要】 讨论了充气压力对热声压缩机的起振温度等性能的影响 ,着重研究了工作压力对热声驱动脉管制冷机性能的影响。对自行研制的驻波型热声驱动脉管制冷机进行了改进和优化 ,在最近的实验中取得了 1 2 0 K的无负荷最低制冷温度 ,达到液化天然气温区。更多还原

【Abstract】 The discussion emphasizes the influence of operating pressure on the refrigeration performance of the pulse tube. A minimum refrigeration temperature of 120K has been obtained from the recent test after the systematic improvements to the self-built thermoacoustically driven pulse tube refrigerator.更多还原
