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。
The effect of inflation pressure on the start-up temperature and other properties of the thermoacoustic compressor is discussed. The effect of working pressure on the performance of the thermoacoustic driven pulse tube refrigerator is discussed emphatically. The self-developed standing-wave thermoacoustic pulse tube refrigerator has been improved and optimized. In recent experiments, a minimum no-load refrigeration temperature of 120 K has been achieved, reaching the temperature range of liquefied natural gas.
