光伏光热系统导热流道传热性能的数值模拟

The Numerical Research On Heat Transfer Performance Of Heat Conduction Channel In Photovoltaic Thermal System

对光伏光热系统实体模型进行简化处理,并建立了包含单条流道、带翅片的单条流道、单侧排列两条流道的三种型式导热流道的物理模型。以20℃蒸馏水为流动工质,借助FLU-ENT分别对三种不同型式的导热流道的传热性能展开数值模拟研究,分析了导热流道的出口平均温度和壁面导热速率。

The mockup of one photovoltaic thermal system had been simplified, and the physical model of three types of heat conduction channels, including the single flow channel, the single flow channel with fins, the nilateral arrangement of two flow channels, had been established. Taking the distilled water of 20℃ as the flowing working substance, the heat transfer performance of three types of heat conduction channels had been simulated numerically by FLUENT, and the average exit temperature and the wall heat transfer rate of the heat conduction channel had also been analysed.
