PURPOSE:To reduce deterioration due to repeated use by a method wherein the title device is provided with heat accumulating material, sealed into a heat accumulating vessel and capable of being supercooled, and a specified supercooling releasing metallic member. CONSTITUTION:When latent heat accumulating material 2 in a heat accumulating vessel 4 is heated to a phase-changing temperature to melt perfectly and accumulate heat, then, is cooled spontaneously in the outside air, the heat accumulating material 2 becomes supercooled condition and the latent heat of solidification is preserved. When a supercooling releasing metallic member 3 is pushed against the outside of the sealed vessel 4, an elastic deformation piece 14a is deformed and an abutment member 13 is contacted slidingly while being made to abut on a flat piece 14b with a pressure. According to this operation, a satiny surface 15 is rubbed with the satiny surface 16 while being made to abut on each other by the elastic deformation force of the elastic deformation piece 14a whereby concentrated stress is applied on the latent heat accumulating material existing between the satiny surfaces 15, 16 and crystallization is started to release the latent heat of the latent heat accumulating material 2. A rubbing pressure between the satiny surfaces is regulated in accordance with the degree of the deformation of the elastic deformation piece 14a whereby the abutment force is not deteriorated by the repetition of the use of the satiny surfaces. |
