摘要

In this investigation, a numerical analysis of a cooling system for a solar panel in a concentration photovoltaic system is conducted. A model of jet impingement /mini-channel heat sink is presented that is supposed to lower the surface temperature of the triple-junction solar cell in a flat-plate concentration solar system. The effect of pin fins angle, for different mass flow rates and concentration ratios on the mentioned system is examined. Temperature distribution, electrical and thermal efficiencies and electrical and thermal exergies are accordingly discussed. Results indicate that the application of a heat sink enhanced with pin fins offers an improvement in heat transfer characteristics with respect to the simple heat sink. Considering the orientation of the heat sink fins, as fins angle increases from 0 to 40 degree, the heat sink temperature reduces from 321.9 K to 321.2 K that results in an electrical efficiency improvement up to 28.95 percent. In addition, for a specified mass flow rate, 0.15 kg/s, the highest electrical and thermal efficiencies reach about 29 and 80 percent respectively for the choicest studied case. The maximum obtained exergy is 2,760.59 W that is related to the case of 40-degree pin fins angle.
