ト１に蓄熱材２が封入されている。Configuration of conventional examples and their problems Conventional heat storage devices of this type are covered with a heat insulating material (not shown) as shown in Fig. 1, and are made of a flexible plastic sheet or plastic and metal foil. A heat storage material 2 is enclosed in a sheet 1 laminated with (for example, aluminum foil).

体側である。 Reference numeral 3 designates a connecting portion in which the sheets 1 are joined by heat sealing or adhesion, and 4 designates a bag-shaped container formed of the sheets 1 and in which the heat storage material 2 is sealed. Also,
A heater 5 was placed outside in contact with the bag-like container 4. In the above configuration, heat storage is performed by the heat storage material 2 receiving heat energy emitted by the heater 5 through the wall 4a of the bag-shaped container 4 that is in contact with the heater 5. . Then, the heat storage material 2 is completely melted (solid→liquid) and heat storage is completed. Further, heat radiation is performed by applying the heat stored in the heat storage material 2 to the body through the other wall 4b of the bag-like container 4. As the heat radiation progresses, the solid 2a of the heat storage material 2 gradually grows from the wall 4b, and all the liquid 2b of the heat storage material 2 becomes the solid 2a, completing the heat radiation. However, the sides on which the heater 5 and the bag-shaped container 4 are located are the outside air and the body sides, respectively.

速やかな蓄熱はできない。加熱器５から蓄熱材２
への入熱速度が遅いと加熱器５は高温となり外気
への放熱損が大きくなり蓄熱効率が低下する。 Heat storage material 2 is used as a body warming device (e.g. vest)
The biggest advantage of using it as a heat exchanger is that it becomes cordless after heat storage is completed, and considering practicality (marketability), it must be able to complete heat storage in a short time and maintain heat dissipation for a long time. The heat dissipation time is mainly
The heat storage capacity of the heat storage material 2 is large and the heat storage material 2 can be used as a body warming device for several hours, depending on the heat insulation performance (heat radiation speed) and the amount of the heat storage material 2, and heat storage can be completed in a short time. Therefore, it is necessary to increase the heating density (W/m or W/m 2 ) of the heater 5. Since the heat input from the heater 5 to the heat storage material 2 is performed in one direction from the wall 4a of the bag-like container 4 which has a limited area in contact with the heater 5, the solid 2a of the heat storage material 2 generally has poor thermal conductivity. Considering these points, rapid heat storage is not possible. Heat storage material 2 from heater 5
If the rate of heat input to the heater 5 is slow, the heater 5 will reach a high temperature, resulting in large heat radiation loss to the outside air and a decrease in heat storage efficiency.

leaks and becomes unusable. For this reason, the heating density (heat radiation amount) of the heater 5 could not be increased too much, and heat could not be stored in a short period of time. In addition, as mentioned above, the outer wall of the bag-like container 4 in which the heat storage material 2 is sealed is a curved surface, so it is difficult to increase the contact area between the bag-like container 4 and the heater 5, which makes it difficult to use as a body warming device. Considering this, the fixation of the heater 5 could not be said to be sufficient. Therefore, there was a risk that the heater 5 would come off the bag-like container 4 and overheat, damaging the device.

The flexible sheets are laminated in correspondence with each other, and a heater is disposed between the laminated flexible sheets in contact with the bag-like container and the connecting portion.

り固定されている。 In FIG. 2, a bag-like container 7 is formed with a flexible sheet 6 such as a laminate sheet made of plastic such as polyethylene, polypropylene, nylon, and aluminum foil, and a bag-like container 7 is filled with sodium acetate trihydrate. A heat storage material 8 such as the following is enclosed. The bag-like container 7 is formed around the heat storage material 8 by adhesive or heat sealing, and is interconnected. 9 is a connecting part. Using two flexible sheets 6 made up of the connecting portion 9 and the bag-like container 7,
The bag-like containers 7 of one flexible sheet 6 are stacked so as to correspond to the connecting portions 11 of the other flexible sheet 10. Further, between the laminated flexible sheets 6 and 10, a heater 13 such as a tubing heater wire or a surface heater is bonded or thermally fused in contact with the bag-shaped containers 7 and 12 and the connecting portions 9 and 11.

接触しているのでしつかりと固定される。 In the above configuration, the thermal energy released from the heater 13 during heat storage is transferred to the bag-shaped containers 7, 12 of the flexible sheets 6, 10 that are in contact with the heater 13,
The heat is transmitted to the heat storage materials 8 and 14 through the connecting portions 9 and 11. Since the heat storage materials 8 and 14 are uniformly heated from their entire circumferences, they melt quickly. However, the temperature remains approximately constant until the heat storage materials 8 and 14 are all melted. In this way, the heat storage materials 8 and 14 can efficiently store the thermal energy released from the heater 13 in a short time. Furthermore, the temperature difference between the heater 13 and the heat storage materials 8, 14 can be reduced, and the heat resistance of the flexible sheets 6, 10 and the heater 13 can be increased. The heater 13 also includes a bag-like container 7, 12 between two flexible sheets 6, 10,
Since it is in contact with the concave and convex portions formed by the connecting portions 9 and 11 over a wide area, it is firmly fixed.

てもよい。 In the above embodiment, only the case where the heat storage materials 8 and 14 were filled in the bag-like containers 7 and 12 was described, but a supercooling preventive agent and a gelling agent may be used as necessary.
また、２枚の可撓性シートを積層して用いた場
合について述べたが３枚以上積層して用いてもよ
い。 Moreover, although the case where two flexible sheets are laminated and used has been described, three or more flexible sheets may be laminated and used.
