Thermal performance of the microchannel with the nanofluid applied on solar cell cooling in Fresnel concentrating system
摘要
Abstract
Heat transfer performance of the spiral microchannel with different concentrating condition,and cooling mediums were calculated by numerical simulation which applied on GaAs cell cooling in Fresnel high concentrating system.And some parameters including the battery surface temperature,heat transfer coefficient,Nusselt number and enhanced heat transfer factor were also studied in this paper.The results displayed that the heat transfer performance of the microchannel was enhanced which refrigerated solar cell in the Fresnel triple concentrating system equalization and optimization when the direct irradiance was 1 000 W/m2.Meanwhile,the pressure drop of the optimized Fresnel triple concentrating system was decreased.The heat transfer characteristics of Al2O3 nanofluid was higher compared with distilled water,and it was increased with the nanofluid particle size became small.However,when the mass fraction and viscosity of the nanofluid was increased,Nusselt number and heat transfer coefficient of Al2O3 nanofluid were increased firstly and then declined,and the pressure drop of Fresnel triple concentrating system was increased gradually.When the mass fraction of the nanofluid was 6％～8％,the heat transfer performance of the nanofluid was suit to refrigerate GaAs cell as a reference condition in which the heat transfer factor of Al2O3 nanofluid was higher relatively.关键词
