摘要：
Based on the experimental setup of a thermoacoustically driven pulse tube refrigeration system, by which a lowest refrigeration temperature of 138K was achieved ill 1999, several improvements have been made to the heating and water cooling system of the thermoacoustic driver and the pulse tube refrigerator, as well as the connection between the driver and the pulse tube. Minimum temperatures of 119.7K and 117.6K have been obtained from the recent experiments with helium and helium-argon mixture filling of 2.0MPa as the working fluids, respectively. It is a significant progress for the present standing wave machine and provides the possibility of liquefying natural gas of 0.2MPa.
