PURPOSE:To enable to flow the inflowing air nearly uniformly through a solar heat collector while being scattered within the collector by a structure wherein either one of the air outlet and the air inlet of the solar heat collector has a through hole located nearly at the central part of the solar heat collector and the other has through holes arranged at both sides of the collector. CONSTITUTION:An air outlet 3 has through holes 7 and 7, which are respectively open at both the sides of a solar heat collector 2, while an air inlet 4 is equipped with one through hole arranged nearly at the center of the solar heat collector 2. Consequently, the air, which flows from said air inlet 4 through an air supply flow passage 15 in the interior of the collector, is nearly uniformly scattered and past through the respective branch flow passages 53.... In addition, while passing through each branch flow passage 53, the air absorbs the solar heat collected by an absorber plate 45 and is heated. Further, because the air flows nearly uniformly over the whole surface of a vessel part 31, the efficiency of heat utilization can be enhanced. Furthermore, the heated air is past through the air outlet 3 having said through holes 7 and 7 at both the sides of a chamber 11 and discharged from an air vent 15 through an air delivery flow passage 19 into a room R, resulting in enabling to air-condition the room R. |
