PURPOSE:To raise the heat collecting efficiency of a heat collecting apparatus, by utilizing a main fluidic medium which absorbs light energy and emits heat energy by cuasing reversible reaction of isomerization. CONSTITUTION:Transparent containers 2 provided with refractive light collecting surface are formed at the top of a box-like body 1, and a main fluidic medium 6 consisting principally of norbornadiene or its derivatives and derivatives of N-carboxyazepine or dicyclopendadiene which is capable of repeating absorption of light energy and emission of heat energy by causing reversible reaction of isomerization is charged in the transparent containers 2. Further, an auxiliary light absorbing plate 12 is disposed at a position near the focal point of a condensing lens formed by the container 2, and a light absorbing container 7 is provided in the box-like casing 1 so that a subsidiary medium consisting of a heat absorbing liquid such as water is passed through or stay in the light absorbing container 7. |
