Özet
It would be misleading to consider only the cost aspect of the design of a solar collector. High service
costs increase total costs during the service life of solar collector. The most effective way to save energy is
by increasing the efficiency in a solar collector by the heat transfer coefficient. In our study, three solar
collectors that have (1,6 x 1,6 m2
) dimensions shape area, have spiral reflective, different flow line length
was made. According to the collector geometry, turbulence occurs in fluid flow and in this way heat
transfer is increased. The results of the experiments were evaluated on the days with the same radiation.
The efficiencies of these four collectors were compared to conventional flat-plate collectors. It was seen
that heat transfer and pressure loss increased depending on shape and numbers of the absorbers.
