Abstract
The effect of collector aspect ratio on the collector efficiency of ba ffled solar air heaters has been investigated theoretically. With cons tant collector area, the collector efficiency increases when the colle ctor aspect ratio increases. This is the same results as those obtaine d in the previous work for flat-plate solar air heaters without fins a nd baffles. Although the collector efficiency of baffled solar air hea ters is larger than that of flat-plate heaters without fins and baffle s, the improvement of collector efficiency by increasing the collector aspect ratio is reverse.
