PURPOSE:To provide a solar heat collecting device with an atmospheric heat collecting capability, for thereby increasing a calorie to be collected per a unit area, by providing an atmospheric passage between fin surfaces and respective fins so as to allow for the passage of atmospheric air through opposite sides of plurality of fins serving to collect a solar heat thereon. CONSTITUTION:A solar heat collecting device comprises a plurality of fins 18 collecting a solar heat thereon and a pipe 17 transmitting the solar heat thus collected to a heat medium. An atmospheric air passage 19 is provided between fin surfaces or respective fins so as to allow for the passage of atmospheric air through opposite sides of fins 18. By so arranging, the heat of atmospheric air can be collected by passing an atmospheric air through, for example, a circular communication port 19 formed in the plane of fin 18. That is, a high convection heat transmission takes place over the entire surface of fin 18, when air flows 21, 22 pass through the atmospheric air communication port at right angles to a heat collecting surface 20. By providing the solar heat collecting device with an atmospheric air heat collecting capability, more calorie can be collected per a unit area. |
