Abstract

Flat plate collector (FPC) is a central component of any solar water heating system. The efficiency of FPC is determined by performance of absorber plate. Absorber plate has conventionally been comprised of copper tubes with brazed fins. The present study is an attempt to investigate the possibility of replacing copper-based absorber system with aluminium and thereby reduce cost significantly. The extra thermal resistance caused by introducing aluminium is compensated by avoiding a fin-tube weld joint with the help of extruded fin-tube arrangement. Thermal resistance analysis of the commercially available collector and modified Al-FPC has been carried out which suggests that the latter has nearly same overall heat loss coefficient as former one. Extruded aluminium fin-tube modules have been fabricated followed by performance testing on commercial and modified collector for over two month period. Performance testing results show that under same solar irradiation and weather conditions the modified collector performs as efficiently as the conventional one. Extrusion process limits the minimum fin thickness possible resulting in considerable increase in the use of aluminium in absorber plate. © 2019, Toronto Metropolitan University.
