| 中文摘要: |
| 本研究将PV/T系统中的冷却流道布置于光伏板上方,利用水等介质可以吸收太阳辐射中的红外波段能量的原理,冷却介质不仅可以吸收光伏板表面的余热也可以吸收太阳辐射中不用于发电的能量,从而有效提高系统的热电效率。本研究建立了表面通道下冷却光伏板模型,改变各项参数,通过计算沿流动方向玻璃盖板和光伏板表面的沿程平均努谢尔数,通过其变化趋势研究该系统中光伏板的传热特性。模拟结果表明:光伏板表面的对流换热优于顶部玻璃盖板表面,且光伏板表面和玻璃盖板表面努谢尔数的变化趋势沿流动方向相反。 |

| In this study, the cooling channel in the PV/T system is arranged above the photovoltaic plate, and the principle that water and other media can absorb the infrared band energy in solar radiation is used. The cooling medium can not only absorb the waste heat on the surface of the photovoltaic panel, but also absorb the energy not used for power generation in the solar radiation, so as to effectively improve the thermoelectric efficiency of the system. In this study, a model of cooling photovoltaic panels under the surface channel was established, and various parameters were changed. The heat transfer characteristics of photovoltaic panels in the system were studied by calculating the average Nuscher number along the glass cover plate and photovoltaic panel surface along the flow direction. The simulation results show that the convective heat transfer of PV panel surface is better than that of the top glass panel surface, and the variation trend of Nuscher number of PV panel surface and glass panel surface is opposite along the flow direction. |
