摘　　要：介绍了整体式太阳热水器(ICSSWH)结构改进研究进展。通过结构改进,强化热分层,降低对流热损失,提高聚光比和集热率;通过材料选择,改善内部传热,提高吸收率,降低辐射热损失。整体式太阳热水器(ICSSWH)在农村地区具备一定竞争优势。The structure advancement of ICSSWH （Integrated Collector Storage Solar Water Heater） was introduced. By means of improving structure of ICSSWH, the circulation pattern was optimized, thermal stratification was strengthened, convection heat loss was decreased in storage tank, and heat collection efficiency was increased in collector. By optimization of material selection, the heat transfer coefficient was increased between collector and tank, heat absorptivity of collector was increased, while radiation heat loss was decreased. ICSSWH is provided with competitive advantage in rural areas.
