摘要：

A small size standing wave thermoacoustic refrigerator driven by a high frequency loudspeaker has been experimentally studied. Instead of water cooling, the cold heat exchanger of the refrigerator was cooled by air through fins on it. By working at 600-700 Hz and adjusting the position of the thermoacoustic core components including the stack and adjacent exchangers, the influences of it on the capability of refrigeration were experimentally investigated. The lowest temperature of 4.1 degrees C in the cold heat exchanger with the highest temperature difference of 21.5 degrees C between two heat exchangers were obtained. And the maximum cooling power of 9.7 W has been achieved.
