囲を汚損する懸念があった。Problems to be Solved by the Invention However, conventionally, most attempts have been made to use a heat storage material that prevents supercooling. That is, the heat storage material is of a type that starts radiating heat upon completion of heating (heat storage). Therefore, it was not possible to radiate heat when necessary, and the application was limited. However, recently, a method has been tried in which heat is taken out from the heat storage material at any time by utilizing the supercooling phenomenon. That is, Japanese Unexamined Patent Publication (Kokai) No. 61-14283 describes a supercoolable heat storage composition containing a heat storage material and hydroxypropylated guar gum as essential components. In this publication, a method is shown in which a heat storage composition is supercooled in a glass bottle and a seed crystal is added when heat is required, or a pointed metal rod is used as a stimulus to collapse supercooling and take out heat. There is. This method is considered to be effective for large-scale heat storage devices such as in the hot water supply field. However, when it is used for a small heat storage device such as a body warming device, it is necessary to carry the seed crystal at all times, which causes problems such as powder loss or acquisition of the seed crystal. Also, when using a sharp metal rod, there are problems in terms of portability and safety.
Further, there is a concern that the heat storage material composition leaks and stains the surrounding area when the container is opened and closed.

る。Further, Japanese Patent Application Laid-Open No. 61-22194 describes a thermal energy storage device comprising an energy storage and a stimulator. This publication shows a method in which a stimulator made of a seed crystal is physically brought into contact with an energy storage material in a supercooled state, and the supercooling is destroyed to extract heat energy. However, this method also has a practical problem when it is used in a small heat storage device. That is, it is necessary to thermally isolate the seed crystal in order to prevent the seed crystal from being melted by being heated (heat storage). However, when the device is small, this thermal isolation is difficult, and even if it is possible, the device is enlarged. In addition, it is difficult to reliably thermally isolate the seed crystal against external stimuli during movement such as carrying and heating under various environments.

る。The present invention is intended to solve the problems of the heat storage device. That is, when a supercoolable heat storage body is used in a small heat storage device such as a heat collecting device, a heat retaining device, or a heating device, heat can be easily stored, and it is possible to conveniently and easily collapse supercooling and take out heat. In addition, the heat storage material does not leak and contaminate the surrounding area.

閉機構部に漏出することがない。Action According to the present invention, if the heat storage body is supercooled, the supercooling does not collapse even if a stress such as shock, bending, or pressure is applied from the outside. However, when the heat storage material impregnated in the capillary body is stimulated, the supercooling easily collapses and heat can be taken out. The collapse of supercooling spreads from the heat storage material in the capillary to the heat storage material in the container. In addition, the capillary body prevents the heat storage material from directly leaking out of the container. Also,
Since the collapse of supercooling is an external stimulus and does not require a seed crystal, there are no restrictions during heat storage. Therefore, it may be heated directly by boiling it in hot water, or the entire heat storage body may be heated by a heater. Further, in the present invention, since the capillary body is provided with a flow prevention mechanism, even if a large pressure difference occurs between the inside of the container and the outside of the outlet due to an increase in internal pressure during heat storage or a compressive load from the outside, heat storage is facilitated. The body does not leak to the opening / closing mechanism through the capillary body.

表面９を濡らす。Hereinafter, each element will be described. The container 2 is made of a material that is non-reactive and incompatible with the heat storage material 7. Especially when it is used for a heat collecting device, it is preferable to use an aluminum laminate film because it requires flexibility. The capillary body 3 is made of a fibrous body made of a material which is non-reactive or incompatible with the heat storage material 7, an open cell body or a sintered body having open cells, and is tightly filled and fixed inside the outlet portion 5. The capillary body 3 has a flow prevention mechanism 4 inside. The flow prevention mechanism 4 is intended to prevent the heat storage body 7 from being sucked up in large quantities by the capillaries and leaking out of the capillaries 3 when the pressure inside and outside the container is re-generated due to the increase in the internal pressure. When the flow prevention mechanism 4 is composed of bubbles, when the internal pressure rises, the bubbles are also compressed and the internal pressure rises, and there is no pressure difference with the inside of the container.
Therefore, transfer of the heat storage material between the container and the bubbles is prevented.
Further, when the internal pressure of the bubbles increases, the closeness of contact between the bubbles and the wall surface increases, and the flow of the liquid in this portion is suppressed. When the flow prevention mechanism 4 is made of powder, if the internal pressure rises and the powder becomes dense, the flow resistance increases and prevents the heat storage material from moving. Further, when the flow prevention mechanism is composed of a thin leaf cylinder, when the internal pressure rises, the thin leaf cylinder becomes flat and the thin leaf objects come into close contact with each other to prevent the heat storage material from flowing. In this embodiment, the opening / closing mechanism 6 is of the cap device type, but may be a screwing type or the like so that it can be easily opened and closed. The heat storage material 7 is a hydrated latent heat storage material such as calcium chloride hexahydrate, sodium sulfate decahydrate, sodium thiosulfate pentahydrate, sodium acetate trihydrate, and the like, and if necessary, a thickener and a stabilizer. Alternatively, it is a mixture of a heat conductive substance and the like. The space 8 facilitates the attachment / detachment of the cap and prevents leakage of the heat storage material such as detachment. Further, in the present invention, the heat storage material 7 easily contacts the capillary body and is sucked up by the capillary tube to wet the surface 9 of the capillary body 3 on the opposite side which is not in contact with the heat storage material 7.

易に崩壊し熱を取り出すことができる。The heat storage body 1 having the above configuration is heated (heat storage) in a sealed state by hot water or a heater. After the heat storage material 7 is sufficiently melted,
When cooled to room temperature, a supercooled material of the heat storage material is obtained. Although the reason is not clear in this state, the supercooled state does not collapse even if a stress such as impact, bending, or pressure is applied to the heat storage body 1. To take out the heat,
Open the opening and closing mechanism and contact the outside, that is, break the sealed state,
The surface 9 of the capillary body is lightly stimulated with a stick, a thin leaf or a finger. Then, the heat storage material 7 in the capillary body 3 easily collapses in the supercooled state and heat can be taken out.

作を100回繰返えしたが全て同じ結果が得られた。A polyethylene pipe containing two polyethylene sintered bodies as capillary bodies is provided by heat fusion in a 100 mm x 120 mm aluminum laminated container. A 10 mm void (bubble portion) was provided between the sintered bodies. The polyethylene pipe is made to have a closed structure by a polyethylene cap. 40 g of sodium acetate trihydrate was enclosed in this container to obtain a heat storage body. A subcooled product can be easily obtained by immersing the heat storage material in 100 ° C hot water for 10 minutes to sufficiently dissolve the heat storage material and then cooling to room temperature. Supercooling did not collapse under any external stimulus in this state. The supercooled state collapsed when the cap of the regenerator was removed to take out heat and the surface of the polyethylene sintered body was gently stimulated with a match stick. This collapse phenomenon spread to the heat storage material in the polyethylene sintered body and reached the heat storage material in the container, and heat could be easily extracted. In addition, no leakage of the heat storage material into the space was observed despite the increase in the internal pressure during heating. Hereinafter, the same operation was repeated 100 times, but the same result was obtained.
発明の効果 以上のように本発明の蓄熱体によれば次の効果が得られ

できる。That is, since the heat storage body of the present invention does not have a seed crystal in the heat storage body, the whole heat storage material can be heated in a sealed state, and a supercooled state can be easily and surely created. Further, since the outside of the container and the heat storage material are separated by the capillary body and the capillary body is provided with the flow prevention mechanism, the heat storage material does not leak to the outside. Further, since the surface of the capillary body is wet with the heat storage material, it is possible to surely collapse the supercooling only by gently stimulating the surface of the capillary body when taking out heat.
したがって、本構成の蓄熱体を用いれば、どこでも簡単
