Abstract: A prototype of standing wave thermoacoustic refrigerator is designed and constructed based on the

characteristics of standing wave and the basic theory of heat transfer. Besides，the methods of analyzing thermoacoustic

effect by pressure acoustics and linear thermoacoustic theory are verified respectively. The results of experiment

show that the cold side can obtain an ideal cooling of 2.16 K when the speaker driver voltage is 7 V，driving

frequency is 315 Hz，and dimensionless thermoacoustic stack location is 0. 27; the driving voltage of

loudspeaker has a positive correlation with the refrigerating capacity in the range of measurement. The experimental

results are well matched by the prediction of the DeltaEC program and linear thermoacoustic theory when use the

physical parameter values of the experimental device，which verifies the feasibility of this analysis method.
