PURPOSE:To make the device smaller by a structure wherein a first heat exchange means, which radiates the heat transferred from a heat collecting part to a heat accumulating part in order to store therein, and a second heat exchange means, which transfers the heat stored in the heat accumulating part to a heat carrier medium in order to transfer outside the device, are arranged so as to be thermally brought into contact with each other. CONSTITUTION:A supply pipe 6 is connected to the lower ends of heat collecting pipes 5, 5... whose upper ends are connected to a collecting pipe 7, of the heat collecting part 2 of a natural circulation type solar heat collecting device 1. A metallic heat radiating pipe 10 and a metallic pipe 11, both of which serve as the first and the second heat exchange means respectively, are arranged slantwise in closely parallel to each other and the pipes 10 and 11 are thermally brought into contact with each other by being fitted with radiation fins or absorption fins. Furthermore, the pipe 11 is filled with heat collecting medium such as aqueous solution of propylene glycol or the like and the vessel 9 is filled with heat accumulating agent such as sodium thiosulfate pentahydrate or the like. Consequently, conventional hot water storage tank and the like can be made unnecessary. |
