| Abstract: | In order to improve the efficiency of a flat plate solar air collector,the flat plate solar air collector with baffles is designed,by using Fluent to analyze the influence on the performance of solar air collector with baffles in different height and spacing of baffles,and the best baffles structure parameters are got.The results show that: in all the research solar air collector with baffles,the comprehensive properties of this collector is the best when spoiler spacing is 800 mm and the height is 150 mm,the best flat plate solar air collector with baffles compared to common solar air collector,its efficiency is improved obviously,and through the caculation by the least square method,its instantaneous efficiency formula is obtained. |
