BACKGROUND ART Conventional spherical phase change heat storage medium enclosing containers have been manufactured by blow molding. That is, a tube (parison) formed by extrusion of molten resin is inflated by being blown with air while being sandwiched between molds having spherical mold surfaces. After the molded product is cooled and solidified, it is removed from the mold, the air inlet protruding from the spherical portion is cut out, and the heat storage medium is injected through the hole left behind. Thereafter, a plug made of the same material is welded using ultrasonic waves or rotational frictional heat.

As the heat storage medium 1, a hydrated compound that causes exothermic or endothermic reactions due to temperature changes, such as CaCl 2 6H 2 O
applies. This CaCl 2 .6H 2 O rises in temperature due to radiation or conduction heat from the surrounding heat medium, and when the temperature reaches 38° C. or higher, it becomes CaCl 2 +6H 2 O, causing an endothermic reaction and storing heat. Next, when the temperature of the heat storage medium falls below 38° C., CaCl 2 and water begin to combine and an exothermic reaction occurs. This suppresses the temperature drop of the heat medium in the surrounding area.

As a heat medium, air, water, antifreeze, etc. are used. The heat medium passes through or remains in the outer periphery of the heat storage medium enclosing container A and in the through-hole A3, whereby heat is taken away or heat is supplied as the outside temperature changes, and a substantially constant temperature is maintained. and,
In the heat storage medium enclosure container of the present invention, the through hole A3
Since water, which is a heat medium, passes through the inside, the heat exchange area increases, promoting an endothermic exothermic reaction to the heat storage medium 1, and causing water and
Heat transfer between the heat storage medium and the heat storage medium is fast, and heat exchange efficiency is increased.
