PROBLEM TO BE SOLVED: To improve the heat storage performance of a heat storage apparatus. SOLUTION: This is a heat-storage tank of such a type that the tank is filled with a latent heat-storage material and the heat exchange between the latent heat-storage material and the heat transfer medium is carried out via the heat transfer wall and is characterized by using, as the latent heat-storage material, a substance that has the ratio of the specific gravity in the liquid phase (dL) to the specific gravity in the solid phase (dS) in the range of 0.5-1.0 (dL/dS), using the heat storage apparatus equipped with the fin structure on the side where the heat transfer wall comes into contact with the latent heat storage material and constituting the fin structure sites and the heat transfer surfaces other than the fin structure sites with a metallic substance where the ionization potential (I1) of the fin structure sites is larger than that (I2) of the heat transfer surfaces other than the fin structure sites. This heat storage tanks are used to constitute the objective heat storage apparatus. |
