Abstract
Disclosed herein are a vacuum insulation panel that improves heat transfer performance while improving durability of a core material and a manufacturing method thereof. The vacuum insulation panel includes a gas-interception sheathing material to cover a core material. The interior of the sheathing material is decompressed so that the sheathing material is hermetically sealed. The core material is formed of a lump of fiber, and the fiber has a hollow part formed therein.
Claims16
A vacuum insulation panel comprising:
- a gas-interception sheathing material to cover a core material, an interior of the sheathing material being decompressed so that the sheathing material is hermetically sealed, wherein
- the core material is formed of a lump of fiber, and the fiber has a hollow part formed therein.
A manufacturing method of a vacuum insulation panel comprising:
- preparing a gas-interception sheathing material formed in a pouch shape;
- forming a hollow part in glass fiber;
- pressing a lump of glass fiber while heating the lump of glass fiber at a predetermined temperature to form a core material;
- inserting the core material into the sheathing material;
- decompressing an interior of the sheathing material;
- and
- sealing the sheathing material.
A refrigerator comprising:
- a body defined by top and bottom walls, side walls, and a rear wall so that the body is formed in a box shape;
- a storage compartment provided in the body;
- and an insulation unit provided between the rear wall and the storage compartment for insulation, wherein
- the insulation unit comprises a vacuum insulation panel, and
- the vacuum insulation panel comprises:
- a core material formed of a lump of glass fiber having a hollow part formed therein;
- and a sheathing material to cover the core material, the sheathing material being hermetically sealed by decompressing an interior of the sheathing material.
