    • A multi-stage thermoacoustic device includes a resonance tube mounted therein a plurality of stacks and a plurality of heat exchangers interlaid with each other adjacent to a second end of the resonance tube. A working fluid is filled in the resonance tube. A driver mounted on a first end of the resonance tube drives the working fluid oscillate in the resonance tube, the working fluid is compressed and expanded and causes temperature oscillation and thermal energy flowing from one end of the stack to the other end. The thermal energy, such as cooling capacity, is finally transferred outward through the heat exchangers on sides of the stacks. The multiple stacks and heat exchangers perform a multiple stage temperature gradient. More thermal energy is transferred, and the working efficiency is improved.
    • 多级热声装置包括安装有多个堆叠的共振管和彼此相邻的多个热交换器,该多个热交换器邻近共振管的第二端。 工作流体填充在共振管中。 安装在谐振管的第一端的驱动器驱动谐振管中的工作流体振荡,工作流体被压缩和膨胀,并导致温度振荡和热能从堆叠的一端流到另一端。 热能,例如冷却能力,最终通过堆叠侧面的热交换器向外传递。 多个堆叠和热交换器执行多级温度梯度。 传递更多的热能,提高工作效率。
