Abstract

A vacuum adiabatic body includes a heat exchange pipeline and a sealing assembly. The heat exchange pipeline includes at least two pipelines which pass through a first plate and a second plate to allow a refrigerant to move between inner and outer spaces. The sealing assembly allows the heat exchange pipeline to pass through the first plate and the second plate without contacting a vacuum space provided between the first and second plates.

Claims (57)

1. A vacuum adiabatic body comprising:

a first plate;

a second plate;

a vacuum space provided between the first plate and the second plate;

an opening provided in at least one of the first plate or the second plate;

a sealer provided at the opening;

a pipeline passing through the sealer; and

at least one block configured to support the pipeline and to shield the opening, the at least one block including a portion inserted into the opening,

wherein the sealer is disposed between the portion of the at least one block and an inner surface of the opening.

2. The vacuum adiabatic body according to claim 1 , wherein the at least one block comprises a first block supported by the first plate and a second block supported by the second plate.

3. The vacuum adiabatic body according to claim 1 , wherein the at least one block comprises a first block provided at the first plate and a second block provided at the second plate, and

wherein the portion of the at least one block includes a first portion provided in first block and a second portion provided in the second block.

4. The vacuum adiabatic body according to claim 1 , wherein the at least one block comprises a first block to surround a first portion of the pipeline and a second block to surround a second portion of the pipeline, and

wherein the first block is spaced apart from the second block.

5. The vacuum adiabatic body according to claim 1 , wherein the at least one block comprises a first block and a second block that are coupled to each other, and

wherein the first block is provided at the first plate and the second block is provided at the second plate.

6. The vacuum adiabatic body according to claim 5 , wherein the at least one block includes a first block and a second block, and the sealer is provided between the first and second blocks and surrounds the pipeline.

7. The vacuum adiabatic body according to claim 1 , further comprising a conductive resistance sheet configured to reduce heat conduction between the first and second plate, the conductive resistance sheet being connected to the first plate,

wherein the conductive resistance sheet defines the inner surface of the opening.

8. The vacuum adiabatic body according to claim 1 ,

wherein the sealer is filled in the conductive resistance sheet and is configured to surround the pipeline.

9. The vacuum adiabatic body according to claim 1 , wherein at least one block comprises a supporter supported by the first plate or the second plate and the portion inserted into the opening and to contact the sealer.

10. The vacuum adiabatic body according to claim 1 , further comprising an adiabatic material provided to shield the at least one block and in which the pipeline passes.

11. A vacuum adiabatic body comprising:

a first plate;

a second plate;

a vacuum space provided between the first plate and the second plate;

an opening provided in at least one of the first plate or the second plate;

a sealer provided at the opening;

a pipeline passing through the sealer; and

at least one block configured to support the pipeline and to shield the opening,

wherein at least one block comprises:

a first block supported by the first plate and including a first insertion part having a first coupling part; and

a second block supported by the second plate and including a second insertion part having a second coupling part that is screw-coupled to the first coupling part.

12. A vacuum adiabatic body comprising:

a first plate;

a second plate;

a vacuum space provided between the first plate and the second plate;

a conductive resistance sheet configured to reduce heat conduction between the first and second plate, the conductive resistance sheet being connected to the first plate;

an opening provided in at least one of the first plate or the second plate;

a sealer provided at the opening;

a pipeline passing through the sealer; and

at least one block configured to support the pipeline and to shield the opening.

13. A vacuum adiabatic body comprising:

a first plate;

a second plate;

a vacuum space provided between the first plate and the second plate;

an opening provided in at least one of the first plate or the second plate;

a sealer provided at the opening;

a pipeline passing through the sealer; and

at least one block configured to support the pipeline and to shield the opening,

wherein at least one block comprises:

a first block including a first supporter supported by the first plate and a first insertion part having a first coupling part; and

a second block including a second supporter supported by the second plate and a second insertion part having a second coupling part that is coupled to the first coupling part;

wherein the sealer comprises at least one of:

a first sealer provided at an interface of the first supporter and the first plate, or

a second sealer provided at an interface of the first supporter and the pipeline.
