构建了一台热驱动的热声制冷机。介绍了一种用于行波热声发动机与两级脉管制冷机耦合的新型耦合器。发动机中产生的压力波的振幅首先在耦合器中被放大，然后波进入制冷机以泵送热量。TE使用氮气作为其工作气体，而PTR仍然使用氦气作为其工作气体。有了这个耦合器，系统的效率提高了一倍。发动机和耦合器在低得多的工作频率下匹配，这对于PTR获得较低的冷却温度非常有利。优化了车钩与发动机的耦合位置。有效地解决了发病问题。通过这些改进，热驱动热声制冷机的最低温度达到18.1K，这是热驱动热声制冷技术用于液氢制冷的示范。
A heat-driven thermoacoustic cryocooler is constructed. A unique coupler composed of a tube, reservoir, and elastic diaphragm is introduced to couple a traveling-wave thermoacoustic engine (TE) and two-stage pulse tube refrigerator (PTR). The amplitude of the pressure wave generated in the engine is first amplified in the coupler and the wave then passes into the refrigerator to pump heat. The TE uses nitrogen as its working gas and the PTR still uses helium as its working gas. With this coupler, the efficiency of the system is doubled. The engine and coupler match at a much lower operating frequency, which is of great benefit for the PTR to obtain a lower cooling temperature. The coupling place between the coupler and engine is also optimized. The onset problem is effectively solved. With these improvements, the heat-driven thermoacoustic cryocooler reaches a lowest temperature of 18.1K, which is the demonstration of heat-driven thermoacoustic refrigeration technology used for cooling at liquid hydrogen ...
