摘　　要：为了推广储热系统在小型太阳能热电站的应用,针对双罐储热系统进行设计、建模,利用ANSYS软件模拟分析,结果表明:熔盐罐内温主体温度随时间变化不明显,边沿与底部温降较大;侧壁保温层比顶部保温层对保温性能的贡献更大;热损失随储热温度的提高而增大,且增幅递减;高径比对热损失影响不大。To promote the application of thermal storage system in small-scale solar thermal power stations, a dual tank thermal storage system was designed and modeled, which was subsequently analyzed using ANSYS software. Results show that the temperature of both the molten salt tank and the main body varies stably with time, while that of the edge and bottom drops greatly. Side wall insulation layer has greater contribution to the effect of thermal insulation than the top layer. The heat loss increases with the rise of storage temperature, with gradually reducing growth rate. The height-to-diameter ratio has little effect on the heat loss.
