Abstract
Disclosed is a vacuum insulation member having a uniform insulation thickness, a refrigerator having a vacuum insulation member, and a method for fabricating a vacuum insulation member. The vacuum insulation member includes: an envelope having gas impermeability and having a certain decompressed space therein; and a core including a plurality of laminated mesh members to support the envelope at an outer side of the envelope.
Claims17
A vacuum insulation member comprising:
- an envelope including a plurality of films whose edges are bonded to each other to form a decompressed space therein;
- and
- a core including a plurality of mesh members stacked on each other to support the envelope at an inner side of the envelope,
- wherein each of the mesh members comprises a plurality of first wires disposed to be parallel to each other;
- a plurality of second wires disposed parallel to each other and crossing the first wires;
- and a fixing part to fix the first wires and the second wires, and
- wherein the fixing part is formed at a crossing of an end portion of each of the first wires with the second wires and other crossings are supported by frictional force between the respective wires.
