摘要
对交叉波形吸热板－波形底板空气集热器的盖板与波形吸热板间滞止空气层内的自然对流换热建立了物理模型，利用数值方法进行数值模拟，并对计算结果进行分析及优化，揭示了平均板温差、波纹板的高度特征比、几何特征比、集热器倾角等参数对换热的影响。
In this paper,a mathematical model of natural convection heat transfer inside the stagnant air layer between the top glazing and the corrugated absorber of a solar air collector with cross corrugated bottom cover is developed.The results of numerical simulation show that the parameters,such as average plate temperature difference,specific hight and geometric ratio of corrugated plate,inclination of the collector……etc,have impact on heat transfer processes of the solar air collector.
