提出一种空气/水双冷型PV/T一体化组件,搭建2套测试平台开展PV/T组件的空冷、水冷、空气-水复合冷却实验,研究不同工作模式下组件的性能表现。实验结果表明：3种工作模式均可对光伏组件进行有效冷却,空冷、水冷、复合冷却模式组件综合效率分别为76.05%、74.51%、84.83%,其吸热板温度较无工质冷却模块分别可降低19.08、27.58和35.16 ℃。为进一步分析设计参数对PV/T组件电热特性的影响,利用ANSYS构建组件的三维数值模型,并通过实验数据验证模型的准确性。模拟显示：采用双风道翅片式结构可有效提升组件电热性能;随着环境温度的升高（10~40 ℃）,组件的综合效率由61.85%增至80.31%。
Abstract
A novel air/water-cooled PV/T integrated module is proposed in this paper. Two sets of test platforms are set up to conduct the air-cooled, water-cooled and air/water-cooled mode experiments on the PV/T module to investigate the performance of the module under various working modes. The experimental results show that the overall efficiency of modules in air-cooled, water-cooled and compound cooling mode is 76.05%, 74.51% and 84.83%, respectively. Additionally, the temperature of the heat absorbing plate can be decreased by 19.08, 27.58 and 35.16 ℃ when compared to the PV module. In order to further analyze the influence of design parameters on the electrothermal characteristics of the PV/T module, a three-dimensional numerical model is constructed by ANSYS, and the accuracy of the model is verified by the experimental data. The simulation demonstrates that the electrothermal performance of the module can be effectively enhanced through finned structure with double air ducts. Moreover, as the ambient temperature rises （10-40 ℃）, the module’s overall efficiency increases from 61.85% to 80.31%.
