PROBLEM TO BE SOLVED: To provide the cooling system of high conversion efficiency, which is provided with a cooling function superior in cooling ability, by making a metallic cooling box which can be sealed adhere to the back of a solar battery panel, providing a porous metallic plate on the inner side of the face and providing a fin on an outer side. SOLUTION: Heat generated in the solar battery panel 1 and it is transmitted to the porous metallic plate 3 in the cooling box 2 from a bac plate. A refrigerant absorbs the heat as evaporated latent heat, it becomes vapor and moves to a face where a heat discharge fin 5 is provided from the porous metallic plate 3. Vapor is condensed and is returned to liquid. Then, heat is moved on the face where the heat discharge fin 5 is provided and moved heat is discharged to atmosphere through the heat discharge fin 5. The refrigerant returned to liquid is absorbed to the porous metallic plate 3 with a capillary action again and the phenomenon is repeated. Then, the heat of the solar battery panel is discharged to atmosphere. Thus, the temperature of the solar battery drops, output is stabilized and conversion efficiency can be improved. |
