Abstract
An objective of the present invention is to store heat into a thermal storing material using a plurality of thermal transport mediums, in a thermal storage device utilizing natural convection of a thermal storage material resulting from temperature difference of the thermal storage material. The thermal storage device of the invention has a plurality of thermal transport mediumsandhaving different temperatures, a thermal storage materialwhich stores heat of the thermal transport mediumsandor whose heat is drawn by the thermal transport mediumsand, a thermal storage portionaccommodating the thermal storage material, and a first and a second thermal storage tanksandformed by dividing an inner space of the thermal storage portion, and a thermal exchange between the thermal transport mediumorand the thermal storage materialtakes place in the individual thermal storage tanks. In order to achieve the above-mentioned objective, the thermal storage device of the present invention is characterized by comprising: inner tanksand, which is formed in at least one of the first and the second thermal storage tanksand, and in which a side thereof opposite to a boundary between the thermal storage tanksandis open; and a thermal exchange portionandformed inside of the inner tanksand, at which thermal exchange takes place between the thermal transport mediumorand the thermal storage material
