部が破損して蓄熱材が漏れ出すことがしばしばあった。4!1 Conventional configuration and its problems Conventionally, in a heat storage element in which a latent heat storage material is sealed in a container made of a laminate film containing at least an aluminum layer and a thermal adhesive layer, the latent heat storage material is sealed in a solid or liquid latent heat storage material in the container. After filling the container with the material, the container was simply sealed. In this method, powder or melt of the heat storage material tends to adhere to the sealing portion, which tends to result in incomplete sealing. Furthermore, even if it appears to be completely sealed, if pressure is applied while heat is being stored, the sealing portion will often break and the heat storage material will leak out.
発明の目的
本発明は、容器から蓄熱材が漏れる危険性がきわめて小

る。OBJECTS OF THE INVENTION The present invention aims to provide a safe heat storage element in which the risk of the heat storage material leaking from the container is extremely small.

したものである。Structure of the Invention The most characteristic feature of the heat storage element of the present invention is that a latent heat storage material is filled in a container made of a laminate film including at least one metal foil layer such as aluminum and a heat sealing layer. The inside of the container is divided into two or more locations separated from each other.

チレン層の４層よりなるラミネートフィルムを用いた。Description of Examples Example 1 The latent heat storage material A shown in the figure is a system in which 2% by weight of lithium fluoride is added to sodium acetate trihydrate as a supercooling prevention material. A laminate film consisting of four layers: a polyester layer of 1211 m long, a stretched nylon layer of 1511 m long, an aluminum foil layer of 9 μm, and a polyethylene layer of 80 μm was used.

内の充填部２に融解した潜熱蓄熱材１０９を充填した。In the case of this laminate film, the fusing layer is the innermost polyethylene layer. Put two pieces of this laminate film together and heat-seal the necessary part 1 so that the internal size is 40 mm.
A container B with a diameter of 100 mm was made. The width of the heat-sealed portion 1 is 10 mm. This container B was stood up as shown in the figure, and the filling part 2 of the container B was filled with the molten latent heat storage material 109.

に２０ｍｍの蓄熱材の不充填部５を残して１０ｍｍ幅で
４を封止して図に示した蓄熱エレメントを作製した。At this time, the heat storage material A was prevented from adhering to the top 3. First, the uppermost part 3 was sealed with a width of 10 mm, and then the heat storage element 4 was sealed with a width of 10 mm, leaving a 20 mm unfilled portion 5 of the heat storage material, thereby producing the heat storage element shown in the figure.

には全林もれなか−・た。When this heat storage element was subjected to a pressure test using a universal testing machine at 80'C, when all the heat storage material was melted, the inner sealing portion 4 broke when about 150 kg of pressure was applied. However, the heat storage material A only entered the unfilled portion 5 and did not leak outside.

部分１．３は全熱変化せず、本蓄熱エレメントがきわめ
て安全であることが確認出来た。In this state, it was further heated at 500 kg1, but the outer sealed portion 1.3 did not change in total heat, confirming that this heat storage element was extremely safe.

を封入する際に、容器が大きければ大きい程耐加圧性が
高くなるという効果によるものと考えられる。By the way, the reason why the uppermost part 3 is stronger is that the latent heat storage material A is less likely to adhere to the fused surface than the 4th part, and not only is it easier to complete sealing, but also a certain amount of the latent heat storage material A
This is thought to be due to the effect that the larger the container, the higher the pressure resistance when enclosing the container.
