Numerical study of heat pipe heat exchanger based on concentrating solar photovoltaic cell system
This paper investigates the effect of surface temperature on the efficiency of photovoltaic cells under high concentrating power,and investigates the coupled fin heat pipe heat sink in concentrating photovoltaic cell systems.Study the effect of the number of fins,distribution and fluid flow on the cell efficiency and surface uniformity of the heat pipe radiator under water cooling and air cooling,and compare it with ordinary radiators.The results show that the minimum temperature of the battery surface with the heat pipe radiator occupies less area,the uniformity is significantly improved,and the battery efficiency is improved;under the working condition of 0.64 m/s flow rate,the fin spacing is 1.5 mm,and the fin thickness is 0.4 mm,the overall performance of the battery is the best,the surface temperature is 314 K,the temperature difference is less than 1 K,the uniformity is best,then the electrical efficiency is 31.25%,and the thermal efficiency is 66.03%.
