Vacuum insulation plate and refrigerator with vacuum insulation plate

Abstract

The invention provides a vacuum insulation plate which comprises a core material, a film coating material and a getter. The film coating material is of a closed structure formed by combining multiplefilm coating sheet layers and is correspondingly provided with a combination portion. The film coating material is closed to form a vacuum containing cavity. The vacuum containing cavity is filled with the core material. The core material is filled with the getter. The vacuum insulation plate is provided with a first face and a second face opposite to the second face. The first face is constructedto be flat, and the second face is provided with a protrusion structure. A flat plate cushion block is arranged at the position, close to the first face, in the vacuum containing cavity and is parallel to the first face. One side of the structure of the vacuum insulation plate is prepared to be of a plane structure and is provided with the cushion block, attachment of the vacuum insulation plateand a to-be-measured plane is facilitated, surface unevenness caused by vacuumizing of the core material is avoided, and therefore uneven shapes are prevented from happening to a shell.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a vacuum insulation panel and a refrigerator with the same. Background technique [0002] Vacuum insulation panel is a kind of vacuum insulation material. It is composed of filling core material and vacuum protection surface layer. It can effectively avoid the heat transfer caused by air convection, so the thermal conductivity can be greatly reduced, and it has the advantages of environmental protection, high efficiency and energy saving. It is the most advanced high-efficiency thermal insulation material in the world at present. With its extremely low thermal conductivity, it has the advantages of thin insulation layer thickness, small size and light weight when the thermal insulation technical requirements are the same. It is suitable for products with high energy-saving requirements. It has great technical and economic significance. Refrigerator doors and...

AI Technical Summary

Problems solved by technology

[0007] Vacuum insulation panels are prepared from core materials, coating materials, and getters by vacuum hot pressing. Due to their special structure, they are generally flat structures, which cannot be bent or deformed, even if the cost of deformed processing is relatively high.

[0008] The core material of the vacuum insulation panel is generally made of glass fiber, fumed silica, open-cell foam, etc. In addition to having a certain strength, the core material in the vacuum insulation panel is also required to have a low thermal conductivity. After the vacuum insulation panel is evacuated, After the core material is squeezed, the surface is uneven. On the one hand, it is easy to cause the vacuum insulation panel to fall off in layers on the inner side of the refrigerator shell. On the other hand, the uneven surface is easy to wrap air during the foaming process, resulting in the appearance of the U shell deformed or wavy
