Abstract:	The influence of collector aspect ratio on the collector efficiency of sheet-and-tube solar fluid heaters has been investigated theoretically. With constant collector area and the distance between tubes, the collector efficiency increases with increasing collector aspect ratio (i.e., either increasing l or decreasing n) as well as with decreasing the inlet temperature for air or water flowing through the tubes. This is the same result as those obtained in the previous work for upward-type or downward-type flat-plate solar fluid heaters.
