This paper describes the experimental study of performance of cold heat exchanger (CHX) in standing-wave thermoacoustic heat engine. The engine is developed using commonly stainless-stell alloy and employ the atmospheric air as the working fluid. The engine generate acoustic wave at 300-400°C temperature difference which imposed between the hot and cold part of the system. The distribution of temperature of cold heat exchanger at inlet and outlet obey the condition of heat transfer where the temperature outlet is higher than temperature inlet because the water carry away all the heat being rejected at the end of the stack. The effectiveness of cold heat exchanger rejecting all the heat is 0.68 at the onset temperature. The range of effectiveness is 0.66 < θ < 0.96 and become saturated at 12 minutes and forward after the experiment started with the value of 0.66. A simplified energy-balance theory adequately predicted a trend in temperature difference for acoustic wave onset, while underestimating actual values. The data presented here would be off interest to other researchers to further study the standing-wave thermoacoustic engine for further improvement.
