Abstract

It is an object of the present invention to provide a thermal energy storage member having sufficient dissipation capabilities and a storage container using the same, and a refrigerator using the same.
A thermal energy storage member 1 includes: a thin-plate outer shape having an opposing upper face 1 a and lower face 1 b ; a thermal energy storage material 3 filled in the inside of a package material 2 ; and a thermal conduction amount adjusting portion 4 that, in a case where difference occurs between temperature at the upper face 1 a side and temperature at the lower face 1 b side, reduces difference in thermal conduction amount per unit of time at the upper face 1 a and the lower face 1 b.

First claim

1 . (canceled)

2 . A storage container comprising:
a container main unit; an opening/closing door capable of opening/closing space within the container main unit; a cooling chamber provided within the space, that cools goods at a temperature lower than the ambient temperature during normal operation; a cooler that cools the inside of the cooling chamber from above within the cooling chamber by natural convection; a thermal energy storage member, disposed below the cooler within the cooling chamber, that stores latent heat from cold air from the cooler; and a holding member that holds the thermal energy storage member within the cooling chamber, wherein the thermal energy storage member includes
a hollow package material having an opposing upper face and a lower face and,
a thermal energy storage material filled in the package material,
and wherein a gap layer is further provided between the upper face side and the thermal energy storage material.

3 . The storage container comprising:
a container main unit; an opening/closing door capable of opening/closing space within the container main unit; a cooling chamber provided within the space, that cools goods at a temperature lower than the ambient temperature during normal operation; a cooler that cools the inside of the cooling chamber from above within the coolie chamber by natural convection; a thermal energy storage member disposed below the cooler within the cooling chamber, that stores latent heat from cold air from the cooler; and a holding member that holds the thermal energy storage member within the cooling chamber, wherein the thermal energy storage member includes a hollow package material having an opposing upper face and a lower face and a thermal energy storage material filled in the package material, and wherein the package material has a wider surface area at the upper face side than the surface area at the lower face side.

4 . The storage container according to claim 2 ,
wherein the cross-sectional area of the thermal energy storage member parallel to a horizontal plane is smaller than the cooler.

5 . The storage container according to claim 2 ,
wherein the package material is provided with holes of which the perimeters have been sealed.

6 . The storage container according to claim 3 ,
wherein the cross-sectional area of the thermal energy storage member parallel to a horizontal plane is smaller than the cooler.

7 . The storage container according to claim 3 ,
wherein the package material is provided with holes of which the perimeters have been sealed.

8 . The storage container according to claim 4 ,
wherein the package material is provided with holes of which the perimeters have been sealed.
