摘　　要：建筑耗能在当下能耗中占据主要地位,其中建筑保温在建筑总能耗的比重居高不下,保温板也在不断朝着绿色节能的方向发展。根据蝴蝶鳞翅表面陷光结构设计的仿生墙板,可以有效减少室内温度过多流失,达到节能的目的。此次针对陷光结构设计了梯形凹坑和圆形凹坑两类模型,6种不同尺寸试样,通过COMSOL有限元模拟软件,研究保温板表面温度和辐射度的变化。对模型的温度和辐射度进行对比分析。结果表明仿生陷光板的温度要高于普通平板,在设置的特定环境下,同一种陷光结构,凹坑的尺寸增大2 mm,保温板表面平均温度降低约0.8%。此次研究旨在为今后仿生保温板实际设计生产提供理论参考。Building energy consumption constitutes a significant portion of overall energy use,with thermal insulation accounting for a substantial share of total building energy demand.Insulation panels are continually evolving towards green and energy-efficient solutions.Biomimetic wall panels designed based on the light-trapping structures found on butterfly wing scales can effectively reduce indoor temperature loss,achieving energy-saving goals.In this study,two types of light-trapping structures-trapezoidal pits and circular pits-were modeled,with six different sample sizes.Using COMSOL finite element simulation software,changes in surface temperature and radiance of the insulation panels are analyzed.Comparative analysis of the models'temperature and radiance revealed that the surface temperature of the biomimetic light-trapping panel is higher than that of a flat panel.Under specific environmental conditions,increasing the pit size by 2 mm for the same type of light-trapping structure results in an average surface temperature decrease of approximately 0.8%.This research may provide theoretical guidance for the practical design and production of biomimetic insulation panels in the future.
