Experimental Studies on the Isothermal and Heat Transfer Performance of Trough Solar Power Collectors

Abstract:

The medium temperature heat pipe is a highly effective heat transfer element through heat exchange due to phase change of the liquid organic working fluid. A medium temperature heat pipe used in solar energy receiver of parabolic trough thermal power generating system has been analysed, and a medium temperature heat pipe with liquid organic working fluid has been designed. The isothermal performance and heat transfer performance of the medium temperature heat pipe with liquid organic working fluid have been tested under various power input and different inclined angles. Test proves that axial temperature difference of half circle heated medium temperature heat pipe is smaller, and the half circle heated heat pipe with inclined angle is 4°and 8°can work stably, having good axial isothermal performance and heat transfer performance, the influence on isothermal performance and heat transfer performance of the medium temperature heat pipe can be neglected.
