本発明は蓄熱剤の融解潜熱を利用して蓄熱する蓄熱体と
その製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat storage body that stores heat using the latent heat of fusion of a heat storage agent, and a method for manufacturing the same.
物質に蓄熱する方法としては顕熱による方法と潜熱を利

熱体容器内の蓄熱剤の状態変化に伴なう潜熱を利用して
蓄熱する場合には蓄熱剤の単位体積尚りの蓄熱量が多く
なり同−熱蓄量を必要とするならば蓄熱体容量を少なく
できるという利点がある。There are two methods for storing heat in a substance: a method using sensible heat and a method using latent heat. In this case, there is an advantage that the amount of heat stored per unit volume of the heat storage agent increases, and if the same amount of heat storage is required, the capacity of the heat storage body can be reduced.

であった。However, with conventional heat storage bodies, it is necessary to reduce the price of the container, which is comparatively expensive compared to the price of the heat storage agent, from the viewpoint of cost, so the heat storage agent is enclosed in a container as large as possible. For this reason, the ratio of the surface area (contact area with the heat medium) to the volume of the heat storage agent becomes small, and when performing heat at, the heat storage agent is not completely melted or condensed within that time, and the usable heat storage is The amount was small, leading to a decrease in the heat storage performance of the heat storage body.

を目的とする。The present invention has been made in view of the above-mentioned circumstances, and involves forming a band-shaped thin film made of synthetic resin on a bag-like container, injecting a melted and liquefied heat storage agent into the bag-like container, and then closing the bag-like container. Forming a heat storage body consisting of an aggregate of finely divided heat storage agents by a manufacturing method in which a large number of heat storage elements, each of which is heat-pressure bonded and has a rod-shaped heat storage agent sealed therein, are lined up in the longitudinal direction of a bag-like container. The purpose of this invention is to significantly increase the ratio of the surface area to the volume of the heat storage body, thereby dramatically improving the heat storage performance.
以下、本発明の実施例を図面に基づいて詳細に説明する
。Embodiments of the present invention will be described in detail below with reference to the drawings.

れている。FIGS. 1 and 2 show a heat storage body according to this embodiment. In the figure, the heat storage body 1 has a melting point of about 30°C, for example.
Caldium chloride (CaCtx6HsO), which is available nearby, is used as the heat storage agent 2, and a large number of heat storage elements 4, each of which is covered with a thin film 3 made of high-density polyethylene having a thickness of α1ss11, are connected at appropriate intervals to form a band. is formed.
このような蓄熱体１の製造方法を第３図に基づいて説明

状の蓄熱体１が完成する。Two upper and lower belt-shaped thin films 3A and 3B made of synthetic resin, for example, high-density polyethylene, are conveyed through the feed row 25 so that both edges overlap. In this conveyance process, first, one of the edges of the thin strips 3A and 3B in a direction perpendicular to the conveyance direction and one of both edges thereof are bonded under one pressure using the heat fusing device 6 to form a bag-like container 7 with one end open. Next, the bag-like container T is stood up vertically and maintained in a tensioned state, and the heat storage agent 2 is injected into the liquid state by heating it above the melting temperature. The side surfaces of the bag-shaped container T are bonded by heat and pressure at intervals of 1.5 mm using a heat-sealing device 8 so that air is not enclosed. As a result, a band-shaped heat storage body 1 is completed in which a large number of heat storage elements 4 are arranged in rows, each of which is formed by dividing the heat storage agent 2 and being covered with thin film II&3.
蓄熱体１の構成単位となっている蓄熱エレメント４０大

それぞれの状態において座屈しないようになっている。The size of the heat storage element 40, which is a constituent unit of the heat storage body 1, is, for example, when the heat storage agent 2 solidifies into a rod shape, it has a diameter of about 15 gourds and a length of about 20 cm! It has become. Such dimensions of the heat storage element 4 are such that even when the heat storage agent 2 melts and becomes liquid, the thin film container surrounding the heat storage agent 2 maintains the same shape as when the heat storage agent 2 is in a solid state. It's up to you what you can get. When the heat storage agent 2 is melted and becomes liquid in a usage position where the tab p1 heat storage element 4 is in a vertical or horizontal state, the thin film container is prevented from buckling in each state.

合わせてその形状が選らべるので非常に便利である。By subdividing the heat storage agent 2 as in the heat storage body 1, the surface area in contact with the heat medium, that is, the heat exchange area, with respect to the volume of the heat storage body 1 is greatly increased, and the heat storage efficiency of the heat storage body 1 is extremely high. improves. Further, since the thin film between the heat storage elements 4 can be easily cut, the amount of the heat storage body 1 can be easily adjusted depending on the purpose of use, making it very economical and hygienic to handle. Furthermore, when the heat storage body 1 is incorporated into a heat storage device, it is very convenient because its shape can be selected according to the storage container, such as a roll shape or a sheet shape.

。Furthermore, since the heat storage elements 4 are each independent,
Even if the thin film 3 is damaged, the heat storage agent in the damaged portion simply flows out or is crushed, so that the loss of the heat storage agent 2 is kept to a minimum, and the subsequent recovery work of the heat storage agent is also easy.
