摘　　要：陶瓷换热板得以在太阳能集热系统中应用,其内部流通结构的阻力特性关系此类集热系统的运行参数和设备配置。就陶瓷换热板内流动阻力的形成,说明理论分析中存在的不确定因素,借鉴"黑盒子"测试的原理,以陶瓷换热板总流动阻力作为分析参量,进行流体实验,研究陶瓷换热板在低流速、变工况下的流阻特性规律,导出其在大规模集热系统优化配置中的应用。The ceramic heat transfer plate flow resistance affects the operation parameters and the device configuration of a ceramic solar collector system. This paper explains the uncertainties within the ceramic heat transfer plate flow resistance in the theoretical analysis, learning the principles of the ＂black box＂ testing and taking the total flow resistance of a ceramic heat transfer plate as the analysis parameter, researches the flow resistance characteristic of a ceramic heat transfer plate at low flow velocity and vari- able operating conditions by fluid experiments. At last, the paper exports its use in large-scale solar collec- tor system optimization.
