摘要

Copper thermosyphon heat pipe charged with distilled water water was used for thermal management of photovoltaic panel. Aluminium rectangular channel filled with waste automobile engine oil was kept in contact with back sheet of photovoltaic panel and 8 heat pipes were inserted in 8 aluminium channel. Novelty of this research lies in the proposed heat pipe based Photovoltaic panel cooling system consisting of thermosyphon heat pipes dipped in aluminium channels filled with oil and channels attached to Photovoltaic back-sheet using thermal grease and comparative study of performance of photovoltaic panel with and without cooling system at different tilt angles combined with optimization of heat pipe considering the parameters such as heat pipe filling ratio, inclination and pressure using Taguchi and ANOVA. Results of Taguchi and ANOVA analysis shows that photovoltaic electrical efficiency improves with heat pipe cooling and optimum values of heat pipe parameters are filling ratio (30%), heat pipe tilt (30°) and pressure inside heat pipe (0.7 bar). Confirmation test using these optimum parameters was conducted and after experimental result analysis, photovoltaic efficiency obtained as 20.63%.
