In this article, we have designed and fabricated the gamma-type Stirling engine based on the compression ratio technique. This engine is attached on a parabolic dish of a solar collector. The engine shows a good performance in terms of compression ratio, external work, total pressure, and engine’s speed. Our engine offers the thermal efficiency of 30.59 % so that it can reach the output mechanical power of 0.934. The temperature difference of 137 K can maintain very well for the heat collection of the solar collector even when the weather conditions are poor. Furthermore, our materials are environmentally friendly and this design is expected to be in the applications of the solar tracker in the future.

Collecting Efficiency

A new trough solar concentrator which is composed of multiple reflection surfaces is developed in this paper. The concentrator was analyzed firstly by using optical software. The variation curves of the collecting efficiency affected by tracking error and the deviation angle were given out. It is found that the deviation tolerance for the collector tracking system is about 8 degrees when the receiver is a 90 mm flat. The trough solar concentrators were tested under real weather conditions. The experiment results indicate that, the new solar concentrator was validated to have relative good collecting efficiency, which can be more than 45 percent when it operated in more 145°C. It also has the characteristics of rdust, wind, and snow resistance and low tracking precision requirements.
