 Comparison of heat sink and water type PV/T collector for polycrystalline photovoltaic panel coolingUsman Jamil Rajput and Jun Yang Renewable Energy, 2018, vol. 116, issue PA, 479-491 Abstract: Cylindrical pin fin heat sinks are not used to cool a panel, which we have done so in the present work and tested it's performance against a traditional single-channel PV/T collector. An older 20 Watt polycrystalline solar cell photovoltaic panel with a standard efficiency of 11.7% is elevated to a high temperature by indoor halogen light of intensity 1378.4 W m−2 in this study. The temperature of 81.7± 2.3 °C temperature at the front and 88.6 °C at the rear under at 0 m2 s−1 wind speeds are lowered using a cylindrical pin fin heat sink (fin density 1.22 fin cm−2). A channel of aspect ratios α* = 0.08 was attached to the rear of the panel as the collector configuration. Temperatures dropped to 58.4 °C with heat sink and 47.9° using the collector. The analysis suggests that heat flux of 667.2 W m−2 at the rear of the bare panel with no cooling is enhanced by 30 and 41.5% by the heat sink and PV/T collector by natural methods. We strongly urge exploration of using the cylindrical pin fin heat sinks to cool the panel under stagnant wind conditions.
