摘　　要：预制式太阳能集热板是一种新型具有渗透结构的集热板。试验通过有金属筛网和无金属筛网形式制作了2种预制式太阳能集热板,采用对比方法,对2种形式的集热板集热效率、热损失系数UL进行了测试。试验结果表明:2种集热板的热损失系数差异不大,采用有金属筛网渗透结构的集热板比无金属筛网结构的集热板综合集热效果更好。Prefabricated type solar heat-collecting panel is a kind of heat-collecting panel with newpermeability structure. Two kinds of solar heat-collecting panels are manufactured for experiment with orwithout metal mesh. Both the collecting efficiency and heat loss coefficient Ul of these two types of panelsare tested through comparison. The experimental results show that there was a slight difference between theheat loss coefficients of prefabricated type solar heat -collecting panels, the panel with metal mesh aspermeability structure shows better thermal efficiency than the panel without metal mesh.
