摘      要：The working principle of an efficient travelling- wave thermoacoustic refrigerator operating in room-tem- perature range has been analyzed and an experimental set-up has been built. The experiment showed that suppress- ing DC-flow streaming was very critical to efficient operation, and an elastic membrane was used to solve the problem suc- cessfully. At the most efficient operating point, the novel thermoacoustic refrigerator achieved a cooling capacity of about 80 W at ?20℃, with a much higher efficiency than previously developed standing-wave thermoacoustic refrig- erator.
