AB  - This paper focuses on a 1 kW-class looped three-stage thermoacoustically-driven cryocooler operating at liquefied natural gas temperature. In this configuration, three identical thermoacoustic engines and one pulse tube cooler are connected by different-diameter resonance tubes. Based on thermoacoustic simulation program, the integral system is designed to achieve high efficiency and large cooling power. Firstly, the optimized dimensions are presented. Acoustic power distribution is then demonstrated to better analysis the energy conversion and transmission process. After that, simulations are performed on the influence of the heating temperature and the mean pressure, which are found to be critical to system performance. The calculated system achieved a cooling capacity of 1170 W and total exergy efficiency of 14.95% at 110 K, showing a good prospect for small-scale NG liquefaction devices.
