solar air heaters are used for applications at low and moderate temperatures such as; crop drying, timber seasoning, and space heating. This method substantially improves the collector efficiency by increasing the fluid velocity and enhancing the heat-transfer coefficient between the absorber plate and air. These types of collectors had been designed as a proposal to use an absorbing plate made of aluminium cans into the double-pass channel in a flat-plate to build absorber plates of SAHs at a suitable cost. In the first type (Type I), cans had been staggered as in order on absorber plate, while in Type II they were arranged in zigzag. Type III is a flat plate arrange with baffles. For the same flow rate, the efficiency of the double pass is found to be higher than the single pass. An efficiency test was used to find the best fin arrangement of the receiver. Air enters the upper channel and lower channel of the air heater flows to outside in the parallel direction. If 2-10 m/s speed limit of air in piping system is assumed, proposed some arrangement fin technology enables an efficiency improvement in relation to the smooth pipe arrangement of the solar collector with black paint.
