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.
