Abstract

A vacuum adiabatic body, a method for fabricating a vacuum adiabatic body, a porous substance package, and a refrigerator including a vacuum adiabatic body and a porous substance package are provided. The vacuum adiabatic body may include a first plate, a second plate, a seal, a support, a heat resistance device, and an exhaust port. The support may include a porous substance and a film made of a resin material, the film configured to accommodate the porous substance therein. Accordingly, it may be possible to provide a vacuum adiabatic body through an inexpensive process.

First claim

What is claimed is:

1. A vacuum adiabatic body comprising:
a first plate to have a first temperature;
a second plate to have a second temperature different from the first temperature;
a seal configured to seal the first plate and the second plate, and to provide a space that has a third temperature, the space to be provided into a vacuum state;
a porous substance to be disposed within the space;
a film configured to accommodate the porous substance; and
an exhaust port configured to exhaust air from within the space,
wherein the air exhausted through the exhaust port includes air inside of the film.

2. The vacuum adiabatic body of claim 1 , wherein the porous substance has a higher emissivity than material of the first and second plates.

3. The vacuum adiabatic body of claim 1 , wherein the porous substance is provided in a state surrounded by the film.

4. The vacuum adiabatic body of claim 1 , comprising a support that supports the first and second plates and is provided in the space.

5. The vacuum adiabatic body of claim 1 , wherein the film is provided in a single layer.

6. The vacuum adiabatic body of claim 1 , wherein the film is made of a resin material such that the porous substance does not pass through the resin material and an external gas or liquid passes through the resin material.

7. The vacuum adiabatic body of claim 1 , wherein at least one hole is provided in the film such that the porous substance passes through the at least one hole.

8. The vacuum adiabatic body of claim 1 , wherein the film has a thickness of 1 to 100 μm.

9. The vacuum adiabatic body of claim 1 , comprising a punching mechanism for puncturing the film.

10. A refrigerator comprising:
a main body having an internal space to store goods; and
a door configured to open and close the main body from an external space,
wherein, in order to supply a refrigerant into the main body, the refrigerator comprises:
a compressor that compresses the refrigerant;
a condenser that condenses the compressed refrigerant;
an expander that expands the condensed refrigerant; and
an evaporator that evaporates the expanded refrigerant,
wherein at least one of the main body and the door comprises the vacuum adiabatic body of claim 1 .

11. A vacuum adiabatic body comprising:
a first plate to have a first temperature;
a second plate to have a second temperature different from the first temperature;
a seal configured to seal the first plate and the second plate, and to provide a space that has a third temperature, the space to be provided into a vacuum state;
an exhaust port configured to exhaust an air from within the space; and
a porous substance package to be provided within the space, the porous substance package comprising a porous substance and a punctured film configured to accommodate the porous substance therein.

12. A refrigerator comprising:
a main body having an internal space to store goods; and
a door configured to open and close the main body from an external space,
wherein, in order to supply a refrigerant into the main body, the refrigerator comprises:
a compressor that compresses the refrigerant;
a condenser that condenses the compressed refrigerant;
an expander that expands the condensed refrigerant; and
an evaporator that evaporates the expanded refrigerant,
wherein at least one of the main body and the door comprises the vacuum adiabatic body of claim 11 .

13. The vacuum adiabatic body of claim 11 , wherein the punctured film includes a hole to communicate between inside and outside of the film.

14. The vacuum adiabatic body of claim 11 , wherein the film is provided in a single layer.

15. The vacuum adiabatic body of claim 11 , wherein the porous substance includes glass wool.

16. The vacuum adiabatic body of claim 11 , wherein the film has a thickness of 1 to 100 μm.

17. The vacuum adiabatic body of claim 11 , comprising a punching mechanism for puncturing the film.

18. A vacuum adiabatic body comprising:
a first plate to have a first temperature;
a second plate to have a second temperature different from the first temperature;
a seal configured to seal the first plate and the second plate, and to provide a space that has a third temperature, and the space is to be provided within a vacuum state;
a porous substance to be disposed inside of the space;
a film configured to accommodate the porous substance therein; and
an exhaust port configured to exhaust air from within the space,
wherein based on the exhaust port exhausting the air, the film is to melt by heat or the film is punched, thereby releasing the porous substance into the space.

19. The vacuum adiabatic body of claim 18 , wherein the exhaust port is provided at the first plate.

20. The vacuum adiabatic body of claim 18 , comprising a getter port provided at the first plate.
