AN COMPARISON OF A NEW TYPE CONICAL SOLAR COLLECTOR WITH A FLAT-PLATE SOLAR COLLECTOR

Irfan Kurtbas ¹

In this study, a new type conical solar collector was designed and its performance was compared with of the plane collectors experimentally. The purpose of this study was to collect the sunlight perpendicular to the surface of the collector all day long and the sun’s movement relative to the collector is tracked statically with no moving parts with this new design. Absorbing surface was produced from copper due to its high heat transfer coefficient. The surface of the copper was painted with mat black colour with a radiation coefficient of 0.96. The circulation pipes were also manufactured from copper and it was placed on the collector surface in helix. Circling the fluid all over the surface the circulation route was increased. The experiments were carried out in three different flow rates. The angle of the plane collector was chosen constant at 37°. The conical type solar collector was compared with conventional flat-plate collector. It was seen that the efficiency of the collector i
