摘　　要：热声制冷技术是一项新型的制冷技术,它具有运动部件少、运行可靠、振动小、寿命长、对环境无污染等优点,在航天、超导、低温电子、低温生物等众多领域有着十分广阔的应用前景。本文阐述热声制冷效应的基本原理和热声制冷循环之后,系统介绍了热声制冷机中共振管、板毪、换热器、动力源(扬声器)等部件和制冷工质的研究情况。同时,指出了扬声器驱动热声制冷存在的问题,并对热声制冷的发展进行了展望。Thermoacoustic refrigeration has been developed as a new and environmentally safe technology with long live, having no moving parts, and being highly reliable. It is expected to be widely applied in aerospace, superconduction, cryo-electronics and cryobiology, etc. In this paper, the basic principle of thermoacoustic refrigeration and the thermoacoustic refrigeration cycle are given. The advance in the inprovement of work fluid and the component parts such as resonator, stacks, heat exchangers, driver (loudspeaker), etc are prensented. The problems and the direction of further research of the thermoacoustic refrigerators are discussed.
