Abstract: A heat storage device includes: a heat storage material that absorbs or release latent heat with a phase transition between a liquid phase and a solid phase; and a heat conduction member that includes a contact surface contacting the heat storage material. The heat conduction member has a thermal conductivity higher than a thermal conductivity of the heat storage material. The contact surface includes an upstream region and a downstream region that is located at downstream side of the upstream region in a flowing direction of a heat medium. A wettability of the contact surface with respect to the heat storage material is higher in the downstream region than in the upstream region.

Abstract: A method for forming a crystal nucleus in a latent heat storage material contains a solvent and a dissolved substance. The solvent contains water as the main ingredient. The latent heat storage material retains latent heat in a supercooled state. The method includes: (a) separating out an anhydride of the dissolved substance by heating or cooling part of the latent heat storage material in the supercooled state; and (b) supplying a droplet comprising water to the anhydride, to terminate the supercooled state of the latent heat storage material, and make the latent heat storage material dissipate heat.
