ある。 The present invention was proposed in order to solve such problems, and the present invention is made of a thin-walled sphere made of a material with relatively low thermal conductivity and whose interior is kept in a vacuum or highly reduced pressure state. This invention relates to a heat insulating element characterized by being formed by layering elastic heat insulating material.

能が更に向上されるものである。 The heat insulating element according to the present invention has a thin wall made of a material with relatively low thermal conductivity as its main body, and the inside thereof is maintained in a vacuum or highly depressurized state, so the thin wall itself has a high degree of heat insulation. Has performance. Furthermore, since an elastic heat insulating material is layered on the outer peripheral surface of the thin-walled sphere, the heat insulating performance of the heat insulating element according to the present invention is further improved.

ある。 A large number of the heat insulating elements are collected and put into the heat insulating space of a large container, and the thin balls of the heat insulating elements and the elastic heat insulating material layered around the outer periphery of the heat insulating elements,
As a whole, an effect similar to vacuum insulation can be obtained, but since each insulation element inserted into the insulation space is mainly composed of thin-walled spheres, adjacent insulation elements are in spherical contact with each other. Since the contact area is small, the heat flow path is limited, and the elastic heat insulating material on the outer peripheral surface of the thin ball also suppresses heat flow.

ている。 Reference numeral 1 denotes a thin-walled sphere made of glass fiber-reinforced plastic having an appropriate diameter and wall thickness, and an elastic heat insulating material 2 such as glass wool or foamed polyurethane having a substantially uniform thickness is layered on the outer peripheral surface of the sphere. The air or gas inside the bulb 1 is extracted, and the bulb 1 is sealed in a vacuum or highly reduced pressure state.

る。 A large number of the heat insulating elements configured as described above are collected and placed in the heat insulating space of the container, and the overall heat insulating effect is similar to that of vacuum heat insulation. At this time, since the heat insulating elements in the heat insulating space are in spherical contact with each other, the contact area is small and the heat flow path is limited, and the elastic heat insulating material 2 on the surface of the heat insulating elements also suppresses the heat flow.
