摘要:: 选取石蜡-十四醇掺混石墨作为多元复合相变材料，应用ANSYS软件建立光伏与相变控温模块的传热模型进行模拟分析与验证。研究不同质量分数的石墨、相变层热导率、热焓值以及厚度对光伏控温效果的影响。结果表明：上述因素都会不同程度地影响光伏组件的温度，其中石墨用量以及相变层厚度的影响最明显。当相变层中添加10%石墨时，光伏高于50 ℃的累计时间最少；当相变层厚度为50 mm时，控温效果最佳。

Abstract:: In this paper,paraffin-tetradecyl mixed with 1-tetradecanol was selected as the multi-component composite phase change materials.Graphite powder was added to enhanced heat transfer.In the numerical study,The heat transfer model of photovoltaic panel and phase change temperature control module was established with ANSYS software for simulation analysis and verification.An experimental system exposed to solar radiation was used to validate the temperature control effect of phase change layer on photovoltaic panel.The temperature control characteristics of phase change layers were analysed for component ratios,thermal conductivity,thermal enthalpy and thickness.The results show that the above factors can affect the temperature of photovoltaic panel for different degrees.When graphite powder accounts for 10% in phase change materials,the cumulative time of photovoltaic panels above 50 ℃ is the least;when the layer thickness is 50 mm,the temperature control effect is the best.
