Abstract

An integral solar powered thermoacoustic engine with a funnel-shaped concentrator was successfully built and tested. The thermoacoustic engine was mounted on the concentrator bottom, and the heat exchanger was located at the focus of concentrator so that the inner surface of the concentrator had no shadow. The thermoacoustic engine and supports racks could be installed without space limitation that made it easy to design, install and maintain, and made the energy transmission to the next stage more efficient as well. The performance test under the real weather condition was carried out. Although the tracking system was very rough, the hot end temperature of stack could still reach about 744 K while the thermoacoustic conversion occurred. The system began to oscillate when the hot end temperature reached 458 K. These preliminary results showed a good potential of the system to be an alternative in near future for the solar thermal utilization.
