【摘要】 介绍了回热器热声制冷机理及发展简况， 并对回热器填料为金属网格和吸附剂两种材料的热声特性作了对比，给出强化吸附剂型回热器热声特性的方法，并提出吸附剂型回热器热声制冷机更应能广泛适用于低温热源、无运动部件、清洁制冷的建议。更多还原

【Abstract】 The development and principle of the thermoacoustic refrigerator is introduced.The comparsion of two types regenerators thermoacoustic characteristic is made.One type is metal regenerator and the other is adsorbent.At the same time,how to verify the thermoacoustic characteristic is given.At last,the conclusion that the thermoacoustic refrigerator with the regenerator of adsorbent powered by gas resonator is suitable for the use of low temperature heat,no moving parts and clean refrigeration is drawn.更多还原
