蓄熱器は有する。(Prior art) In addition to the heat capacity of the heat storage material itself, the heat storage material has a large surface area (heat transfer surface area per unit volume) to reduce dead volume and flow resistance inside the heat storage material. Desired for improved performance. For this purpose, heat storage devices are
As seen in No. 435 (November 1982), a structure is adopted in which a large number of copper wire meshes made of metal wires such as SUS-27 are laminated inside a cylindrical body. That is, the heat storage device has a structure in which a wire mesh 1 is laminated on a cylindrical body 2 as shown in FIG.

Once the material, mesh number, and wire diameter are determined, the heat capacity, specific surface area, dead volume, and flow resistance are determined naturally. Therefore, in order to increase the heat capacity and specific surface area, it is possible to make the wire mesh larger and increase the number of laminated layers, or to reduce the diameter of the strands and increase the number of meshes. This results in an increase in dead volume or an increase in flow resistance due to a decrease in the opening amount, which does not improve the performance of the heat storage device.
