It relates to a thermal member.

効な空調手段となりうるちのである。BACKGROUND ART In recent years, in the field of buildings, heat storage building materials that increase the heat capacity of a room have been used for the purpose of creating a comfortable indoor environment with little temperature change. After the latent heat storage material in the heat storage building material stores heat (or cold storage), it responds to changes in indoor temperature, exchanges heat with the indoor air through the indoor building material surface (heat radiation surface), and undergoes a phase transition. , which can radiate or absorb heat and maintain a constant temperature environment indoors. Additionally, since no external energy is used during this period, it can be an effective means of air conditioning from a cost standpoint.

、蓄熱時間を短縮しようとするものである。Here, the following ideas are known as methods for improving heat storage efficiency when storing heat in heat storage members such as the above-mentioned heat storage building materials. That is, this is a method in which latent heat H heating materials having different phase transition temperatures are arranged in layers from the inner surface to the outer surface of the heat storage member so that the phase transition temperatures of the respective layers increase or decrease. This is intended to shorten the heat storage time by allowing the phase transition of the latent heat storage material from the inner surface to the outer surface of the member to occur simultaneously during heat storage.

し、密封した後積層している。However, latent heat storage materials function by repeating phase transitions, and during this process they melt and
It is difficult to handle because it takes an amorphous liquid phase. Therefore, in the past, in order to laminate melting latent heat storage materials into a plurality of layers having different phase transition temperatures, as shown in FIG.
, 2r are filled into separate panels 8a, 8b, and 8c, sealed, and then laminated.

っている。[Problem B to be Solved by the Invention] The conventional example described above has a drawback in that it has a weak resistance against earthquakes and other shocks because it has an overhanging structure. This is because if the partition walls of each panel are torn due to deformation due to impact, latent heat storage materials with different phase transition temperatures will flow out and mix when melted during the phase transition process, breaking the temperature gradient. Therefore, this product has a structure that does not allow nailing or cutting.
本発明は、上記従来技術の問題点に鑑み、その目的とす

It is characterized by the fact that it is located
［作用１

ることはない。Therefore, even when the latent heat storage material undergoes a phase transition and becomes an amorphous liquid phase, it behaves as a microscopic solid, and even when an impact is applied, the latent heat storage material between each layer does not flow out or mix as a whole. , its functionality is not impaired, and
The outflow loss of the latent heat storage material due to nailing, cutting, etc. is also limited to local capsule destruction, and its function as a whole is not lost.

部材である。[Effects of the Invention 1] The heat storage member of the present invention includes a capsule heat storage material in which granules are impregnated with a latent heat storage material, and a coating for preventing seepage of the latent heat storage material is formed on the outer shell of each of the latent heat storage materials. The heat storage material between each eyebrow is distributed and arranged in layers so that the phase transition temperature has a temperature gradient from the inner surface to the outer surface of the base material. It does not mix and is resistant to impact, and the outflow of the latent heat storage material due to nailing or cutting is limited to local capsule rupture, and its function as a whole is not impaired. It is a heat storage member with good heat storage efficiency that allows for
