Specifically, the present invention relates to heat storage technology that uses latent heat to store and utilize this heat. It is related to vessels.

器に大きな応力を発生させるなどの不都合があった。(B) Conventional technology When using polyethylene as a heat storage material by utilizing the absorption and release of heat associated with melting and crystallization, 1) it is inexpensive and highly safe; 2) there is no supercooling or phase separation; 3) It has many advantages such as not being corrosive. However, if polyethylene as a factory product is used as it is as a heat storage material, 1
) When heated and melted, it becomes sticky and sticks to each other and forms clumps, so if it is filled into a heat storage device, it may block the flow path of the heat medium or prevent heat exchange between the heat medium and the heat storage material. 2) Since the volume expansion during melting is large, there are disadvantages such as generating large stress in the heat storage device.

願昭６ｇ−７９３９７０号）。The present inventors solved these inconveniences by subjecting polyethylene to R-ray cross-linking and shape stabilizing treatment such as plating (Japanese Patent Application No. 1983/1999 Goo/R2ri No. 35; Gu 1/Gu 2 Gu 3 No. Otsu, special application No. 1983-3737/). In addition, the polyethylene heat storage material developed in this way was treated to prevent deterioration, and a polyethylene heat storage material with improved durability was developed.

塊化が起こるという欠点があった。When using a heat storage device filled with polyethylene heat storage material that has been subjected to shape stabilization treatment, the greater the degree of the treatment, that is, the higher the irradiation dose in the case of RTA. The greater the degree of heat retention, the smaller the heat accumulation (1T) per unit type fff of polyethylene, and the faster the rate of deterioration. Similarly, as the amount of coating increases, the amount of heat storage per unit weight decreases.Therefore, if the degree of shape stabilization treatment is suppressed, a polyethylene heat storage material with excellent heat storage performance can be obtained. When the heat storage material is used after being filled in a container, it has the disadvantage that, if the shape stabilization treatment is insufficient, it will stick and form lumps due to the pressure exerted by the heat storage material's own weight.

器の製作及び充填に莫大な費用がかかり、蓄熱器が非常
に高価なものになる。In order to prevent this, encapsulation is generally used to fill polyethylene into small containers, but this method requires enormous costs to manufacture and fill the small containers, making the heat storage device very expensive.
