摘要：
In the present work, a comparison study of two parallel plate collectors (TPPC) with parallel tubes collectors (PTC) and serpentine tube collectors (STC) has been carried out. New derivations and analyses for the TPPC were developed and applied for the collectors simulation. The final results indicated that the efficiency of the TPPC is about 6% more than the STC and about 10% more than the PTC. This refers to the uniform temperature distribution over the absorbed plate surface as well as the uniform distribution of the working fluid between the two plates. (C) 1997 Elsevier Science Ltd.
