| 摘 要： | 设计并制作了一台大型多功能行波热声发动机，该热声发动机长4．5m，高1．25m，设计最大输入功率5kW。它不仅可以用于行波与驻波混合型热声发动机实验，还可以单独进行行波环路实验及热声发动机驱动脉管制冷机实验。该热声发动机中没有任何运动部件，同驻波热声发动机相比起振温度低、压比大，这对低品位能源的利用具有重要意义。着重介绍该热声发动机系统的研制和测量系统的组成，相关实验结果将另文介绍。

| Abstract: | A large-scale multi-function thermoacoustic Stirling heat engine has been designed and constructed.With the length and height of 4.5 meters and 1.25 meters respectively,the engine is designed to have the maximal input power of 5 000 W.It can operate in traveling wave mode with only the torus in experiment,in hybrid mode of standing wave and traveling wave with the whole engine working.It can be also used to drive a pulse-tube refrigerator.In comparison with standing-wave heat engine,it has lower onset temperature and higher pressure ratio.which is of great significance for introducing a variety of energies of low quality into thermoacoustic engines,such as solar energy,waste vapor energy and so on.This paper puts emphasis on the construction of the engine itself and the composition of the measurement system.Relevant experimental results will be presented in the following paper. |
