Abstract

A heat pipe receiver is designed for a small tower solar power station in this article. Real-time optical simulation procedures are developed based on Monte Carlo ray tracing method and mixed programming method. The spatial and temporal distribution of hea flux on the surface of a single heat pipe and the dynamic distribution of energy on the surface of the heat pipe receiver are studied in detail. The real-time optical performance of the receiver is also analyzed. The results show that the solar flux on a single heat pipe exhibits a significant non-uniformity. On the summer solstice, the total energy absorbed by the heat pipe near the receiver center is approximately 6.9 kW. On the spring equinox and summer solstice, the maximum optical efficiency of the receiver is approximately 75%; whereas the value is only 61% on the winter solstice. The results are helpful to the further study of the solar-thermal mechanism of the heat pipe receiver.
