介绍了一热声压缩机实验装置。这种新型的压力波发生器整体无运动部件、无滑动密封，具有结构简单、运行可靠和寿命长等优点，在空间应用中具有发展前景。分别以氦气、氮气为工质进行了实验，输出的压力波的最大振幅约为平均压力的３％～１０％，采用氦工质和氮工质时的最大压比分别达１．０６和１．１，频率分别为７０Ｈｚ和２５Ｈｚ。 A thermoacoustic compressor experimental device is introduced. The new pressure wave generator has no moving parts and no sliding seal as a whole, has the advantages of simple structure, reliable operation and long service life, and has the development prospect in space application. Experiments were carried out using helium and nitrogen as the working fluid respectively. The maximum amplitude of the pressure wave output was about 3% -10% of the average pressure. The maximum pressure ratios of helium working medium and nitrogen working medium were 1.06 and 1.1, the frequency is 70Hz and 25Hz respectively.
