A carton paper overhanging part is added to the bottom of the selective coated collector. An artificial suction effect is tried to be constituted by using two fans. In this case, air pressure in the chambers is increased but isn’t enough to provide air flow by convection. As seen in Table 1, the surface temperatures of the collector are variable. The surface temperature values are rather high in the middle part of the collector. So increase of the temperature and velocity of the incoming air from bottom of the collector are unproportional. Consequently air exit from the top of the collector is unrealized by reason of air flow losses.
