叠层孔隙尺寸是热声制冷机设计中的一个重要参数。本文报道了孔尺寸对热声器件性能影响的定量实验研究。平行板堆与板间距变化之间的0.15和0.7毫米制造和测量。性能测量表明，0.25 mm （2.5 deltak）的板间距对于冷却功率是最佳的。当间距为0.4 mm （4 delta）时，温度最低。性能的最佳间距约为0.3 mm （3 delta）。得出的结论是，热声制冷的最佳条件是板间距约为穿透深度的3倍（3 deltak）。
The characteristic pore dimension in the stack is an important parameter in the design of thermoacoustic refrigerators. A quantitative experimental investigation into the effect of the pore dimensions on the performance of thermoacoustic devices is reported. Parallel-plate stacks with a plate spacing varying between 0.15 and 0.7 mm are manufactured and measured. The performance measurements show that a plate spacing in the stack of 0.25 mm (2.5 deltak) is optimum for the cooling power. A spacing of 0.4 mm (4 deltak) leads to the lowest temperature. The optimum spacing for the performance is about 0.3 mm (3 deltak). It is concluded that a plate spacing in the stack of about three times the penetration depth should be optimal (3 deltak) for thermoacoustic refrigeration.
