摘　　要：热声制冷作为一种很有前途的制冷方法 ,在国内外相关领域引起了极大兴趣。热声制冷机由声发生器、共振管、板叠及高、低温换热器等部分组成。对声驱动器的振动膜及其冷却系统、气体弹簧系统、高、低温换热器进行了初步改进 ,使制冷机冷端温降从原来的 1 2°C提高到 2 7°C左右 。As a new type refrigeration technology,thermoacoustic refrigeration achievement has attracted more and more attention.The thermoacoutic refrigerator consists of acoustic driver?resonator?hot exchanger?stack and cold exchanger.Some improvements have been done on the viberation film and its cooling system of the acoustic driver,gas spring system and hot and cold heat exchangers.By using atmosphere as working fluid,a temperance difference as high as 27 °C has been achieved by the refigerator with input power of only 20 Watt.
