| 摘 要： | 碟式太阳能行波热声发电是近年来兴起的新型热发电技术,具有可靠性好、潜在效率高、分布灵活等优点。本文介绍了正在研制的一套1 kW碟式太阳能行波热声发电系统。该系统利用碟式集热器收集太阳辐射热量,通过高温热管将热量传输到发动机热端,再采用行波热声发电机进行热-电转换。初步调试采用高频加热模拟太阳能,以3.5 MPa氦气为工质、加热温度为751℃和798℃时分别实现了116 W和255 W的电功输出。实验验证了系统的可行性。目前系统的安装调试仍在进行中,相关的实验结果将在后续的文章中进行报道。

| Abstract: | Solar dish traveling-wave thermoacoustic electricity generator,which has advantages on high reliability,high intrinsic efficiency and high flexibility,has been developed as a novel thermoelectricity device in recent years.In this paper,a 1 kW solar-powered traveling-wave thermoacoustic electricity generation system has been built.In this system,a dish solar collector is used to collect the solar irradiation,a high-temperature heat pipe is used to transfer the heat to the hot end of the traveling-wave thermoacoustic heat engine and the generator is used to convert the heat to the electricity.In the preliminary experiments,a high-frequency induction heating machine is used to simulate the sunlight and electrical powers of 116 W and 255 W are achieved at 751℃and 798℃heating temperature with 3.5 MPa pressurized helium.The results show the feasibility of the whole system.Nowadays,system improvements are under way and more results will be reported in the future. |
