| 摘 要： | 透明蜂窝的太阳透过率是衡量平板式太阳能集热器性能的主要参数.本文考虑入射光线所在平面垂直于集热器表面的情况,从而将光线在蜂窝内部的复杂的传播过程简化为在一个矩形单元内的二维多次反射.根据几何光学原理,推导出蜂窝的有效透过率的计算公式:τe=(1-Atanθ+N)+(Atanθ-Nρe]τ2ρNe.根据公式,透明蜂窝的有效透过率为入射角θ、材料的透射率τ和反射率ρ、以及蜂窝单元的高宽比A的函数,与蜂窝的具体尺寸无关.该公式提供了计算透明蜂窝透过率的一个简单而有效的方法. |

| Abstract: | Solar transmittance in the transparent honeycomb structure is an important parameter to the performance of the flat plate solar collector.By considering the case when the incident light is perpendicular to the collector surface,the complicated light transmitting process in the honeycomb structure can be simplified as a two-dimensional light reflection process.A mathematical formula for the transmittance of transparent honeycomb structure is derived based on the principle of geometric optics,which provides a... |
