摘　　要：设计了一种预制式成型的新型太阳能高效集热板构件,其结构主要是:利用吸热体流道间附加渗透金属筛网结构,墨绿色磁漆添加氧化铁、氧化铜、氧化镁混合制作的吸热涂层,框架采用双层塑钢型材叠加而成的复合框体,盖板为双层普通玻璃,整体形成了密闭性良好的空气流通道。该集热板应用于太阳能建筑的构建,即可替代Trombe墙做集热蓄热墙体结构,也可作为外挂集热板用于室内加热,能有效提高和完善建筑的节能效果,易于规范其施工过程,保证太阳能集热效果。通过模拟及分析,确定了集热板进、出气口布置形式和大小,并对其热损系数UL进行了对比测定,表明其蓄热保温性能稳定良好。This paper focuses on a new type of high efficient prefabricated solar collector. Mesh wire screen used between absorber and air passage, heat absorbing coating used enamel in dark green with iron oxide, copper oxide and magnesium oxide, double plastic-steel windows used as body and covered of double common glasses are main structure of high efficient prefabricated solar collector, which ensure air pas- sage closed. The high efficient prefabricated solar collector can be used as collector-storage wall instead of Trombe wall or set on the wall to raise energy saving and standard construction easily. The size and position of air inlet and outlet can be sure by simulation and analysis, and heat loss coefficients （UL） are comparative determination, the results show that the high efficient solar collector has good thermal reservation and thermal insulation.
