IIR document

A thermoacoustically-driven single-stage pulse tube cryocooler operating below 35 K.

Author(s) : HU J., LUO E., WU Z., et al.

Summary

By using a novel pressure-wave amplifier to connect a thermoacoustic heat engine and a pulse tube cooler and installing an acoustically transparent but gas-blocking membrane to separate the nitrogen in the engine and the helium in the cooler, the efficiency of the acoustic power utilization of the system was highly improved and the working frequency was greatly decreased. Eventually, the heat-driven thermoacoustic cryocooler reached a lowest temperature of 34.1 K.
