%X The present work investigated the solar collector
system with triangular longitudinal fins fixed to the absorber surface at
different configuration. Four models of collectors were manufactured with
different absorber plates made from aluminum material. The experiments were carried out at the winter
session in the climate of Iraq¡ªRamadi city with longitude (43.268) and latitude
(33.43). The experiments have used three values from (0.027 to 0.037) kg/s. The
results showed that the temperature difference increases gradually until midday
and begins decreasing gradually until it becomes zero at sunset. Maximum temperatures difference has been obtained
at the fourth type which is (20.6 ¡ãC), and maximum efficiency and exergetic
efficiency (99.9%), (43.08%) respectively. A comparison has been made with previous works for
thermal and exergetic efficiency. The comparison showed good compatibility
between results; the
percentage of error does not exceed 3%. The results proved that the existence of fins was a good
technique for enhancing the thermal performance of double pass solar collector with a non-effective
increase in pressure drop.
