Study on Coupling in a Thermoacoustic Driven Pulse Tube Refrigerator
Zhileng xuebao, 2018 Thermoacoustic-driven pulse tube refrigerators are usually coupled directly or by long tubes called acoustic amplifiers. With these coupling methods, the efficiency of the whole system is quite low because of the nonideal acoustic field and flow losses ...
