This thermal storage tank T is often installed in a building wall or under the floor, for example, as an installation target part, and excess air is circulated by circulating indoor air in the space where the thermal storage tank T is installed. The amount of heat can be stored or the stored heat can be reduced to air and used as a means of air conditioning such as heating or cooling, so that the heat can be used effectively.

  As shown in FIG. 2, the heat storage block body B is configured by a heat storage capsule group in which a plurality of flat heat storage capsules C are stacked and integrated in the thickness direction. And the end plate 2 provided with the engaging part K which can be engaged with another heat storage block body B arrange | positioned adjacently is integrally attached to the both ends of the said heat storage block body B. As shown in FIG.

The heat storage capsule C is mainly composed of a capsule container main body C1 and a heat storage material C2 filled in the capsule container main body C1 (see FIGS. 3 and 4), and as shown in FIG. A heat medium such as air is circulated through the gap S between the capsule container main bodies C1 of the capsule group so as to exchange heat.
Further, the heat storage material C2 is hermetically sealed between the face material portions 3 by sealing and welding a pair of face material portions 3 as shown in FIG. The housing part 4 for housing in a state is formed, and both the outer surfaces formed by the face material part 3 are configured to be uneven so that the surface area can be increased and the heat exchange efficiency can be improved. ing. As a specific example, the capsule container body C1 is configured by using a pair of face material portions 3 (formed in a substantially rectangular flat shape) made of synthetic resin such as polyethylene and polypropylene, for example. The container portion 4 in a sealed state is formed in the inner space by fusing the double-sided material portion 3 at the entire outer edge of the capsule and at a plurality of locations in the center in the width direction.
The capsule container body C can be formed by a sheet molding method, a blow molding method, an injection molding method, or the like.

The capsules 6 can be integrally connected by passing the bolts 6 and screwing and tightening the nuts at the tips. The heat storage block body B is configured by the heat storage capsule group with the end plate thus bolted.

  The heat storage material C2 is, for example, a mixture of calcium chloride hydrate and water, or a material using latent heat that undergoes phase transformation with heat absorption / release, such as various plastics, paraffins, and waxes having a low melting point. Can be configured. For example, when the capsule is used for air conditioning of a general building, it can be considered that hot air in a living space is guided to the capsule to store heat. At this time, in the case of the material using the latent heat, as an example, it is assumed that the room temperature fluctuates between about 18 ° C. and 27 ° C., for example, using a material capable of phase transformation at a temperature around 23 ° C. Can be mentioned. When using latent heat, a large amount of heat absorption / discharge can be secured. Moreover, it is also possible to use the substance using the sensible heat as the heat storage material C2 instead of the latent heat.

The outer peripheral portion of the bolt insertion hole 2a is formed as a countersink portion so that the enlarged head portion of the bolt 6 and the nut 9 screwed into the bolt 6 are accommodated. Therefore, the bolt 6 and the nut 9 can be attached in a state that does not protrude from the surface side of the end plate 2.
Further, an engagement portion K formed of a bent piece portion 10 formed by cutting and raising a part of the end plate 2 is formed on the side of the bolt insertion hole 2a of the end plate 2. The bending direction of the bent piece portion 10 is set in the same direction for both end plate 2 and is bent along the width direction of the heat storage capsule C in this embodiment. By engaging the engagement portion K with the engagement portion K of another heat storage block body B, the heat storage block bodies B adjacent in the thickness direction of the heat storage capsule C can be engaged and connected. .
Specifically, as shown in FIG. 7, the two heat storage block bodies B are arranged in a state where the bending directions of the respective bent pieces 10 face each other, and are relatively close to each other along the width direction of the heat storage capsule C. If it does, mutual bending piece part 10 will mesh | engage and both heat storage block bodies B can be engaged. Further, the disengagement can be easily performed by relatively separating both the heat storage block bodies B in the opposite directions.
Therefore, as shown in FIG. 7, even in a state where a large number of heat storage block bodies B are installed side by side, it is possible to easily take out only an arbitrary heat storage block body B or re-install it in its original position. Thus, it is possible to easily perform maintenance and replacement.

  According to the heat storage block body of this embodiment, the heat storage tank T in a stable state can be easily formed simply by engaging a plurality of objects with the engaging portion K. Moreover, the capacity | capacitance and shape of a thermal storage tank can be changed only by changing the number and arrangement | positioning of each thermal storage block body, and the freedom degree of design becomes high.
