Nucleation device, method of manufacturing the same, and heat storage device provided with the nucleation device

摘要

PROBLEM TO BE SOLVED: To obtain a nucleation device capable of ensuring induction of crystallization of a latent heat storage medium in a supercooled state, with a simple mechanism.SOLUTION: Employed is a nucleation device 1 crystallizing a latent heat storage medium in a supercooled state, using a deformation of a flexible plate member including a groove 3 containing inside an anhydride of a hydrated salt that is a main component of the latent heat storage medium and formed in at least one surface of the plate member. The nucleation device 1 is used while providing an accumulator 11 in the latent heat storage medium 15. A method of manufacturing the nucleation device 1 includes: a step of forming a groove 3 in at least one surface of a flexible plate member; and a step of arranging an anhydride of a hydrated salt of a heat storage medium in the groove.
