PCM结合内外翅片强化光伏板冷却性能研究OA

The power generation efficiency of photovoltaic(PV)modules is negatively correlated with operating temperature.It focuses on the photovoltaic-internal and external fins-phase change material(PV-F-PCM)system.Through comparative experiments and simu-lation studies,it finds that within the irradiance range of 600~1000 W/m2,the PV-PCM system reduces its surface final temperature by 17~20℃compared to traditional PV systems,while the average maximum power increased by 50%~80%,and the cooling efficiency improves with enhanced irradiance intensity.The surface temperature of the photovoltaic panel decreased with an increase in phase change material thickness.The internal(triangular)and external(rectangular)fins significantly enhance the overall thermal manage-ment performance of the photovoltaic system when close to the phase change material backing compare to other internal and external fins.Through data analysis,it determines that the PV-PCM system with an irradiance of 1000 W/m2,an inclination angle of 30°,and a thickness of 40 mm,combined with internal(triangular)and external(rectangular)fins,is the optimal working condition.It provides a theoretical basis and engineering optimization path for the development of new high-efficiency photovoltaic cooling technologies.
