考虑散热与模态协同的光伏组件优化设计方法
Optimized Design Method for Photovoltaic Modules Considering Heat Dissipation and Modal Synergy
摘要
Abstract
To enhance the service life of photovoltaic modules during operation,it is essential to investigate the heat generated under actual operating conditions.Therefore,on the basis of steady-state thermal and modal simulation techniques,this paper compares the impact of different crossbar structures added to the backsheet of photovoltaic modules on heat dissipation,and proposes a crossbar structure with a trapezoidal bottom surface demonstrating superior heat dissipation efficiency compared to other configurations.Secondly,combining the parameter sampling design method,it compares the thermal performance and structural characteristics of cooling crossbars under different parameters to optimize the crossbar dimensions.The simulation results demonstrate the feasibility of the proposed optimization method.Compared to the unoptimized shuttle shaped crossbar structure,the optimized photovoltaic module exhibits lower strain and maximum module temperature in the first-order mode,achieving a temperature reduction of 7.215 ℃ and a deformation reduction of 1.711 mm.Finally,simulation validation using a 3×3 photovoltaic array model confirms that the optimized photovoltaic system achieved a maximum power output increase of 133.904 W compared to the unoptimized module,validating the rationality of the optimization design.关键词
