<p><P>PROBLEM TO BE SOLVED: To provide a solar heat collecting structure of high durability, capable of preventing not only whitening and cracking of a transparent porous heat insulating material composed of silica aerogel, but also damaging even when a solar heat collecting material does not radiate heat for utilizing solar heat during collecting solar heat by the solar heat collecting material. <P>SOLUTION: Members prepared by charging the transparent porous heat insulating material 2 composed of silica aerogel between a glass plate 3 and a heat-resisting translucent film 4 opposed to each other, in an airtight state, are faced to each other in a state that the translucent films 4 are separated from a solar light receiving face 1c of the solar heat collecting plate 1, and diffusion of solar heat collected in the solar heat collecting plate 1 through the glass plate 3, the transparent porous heat insulating material 2 and the translucent film 4 is prevented by the transparent porous heat insulating material 2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
