Background
The vacuum heat-insulating plate is composed of a surface high-barrier packaging bag, a core material, a getter or an adsorbent. The gas remained in the heat insulation space is removed by improving the internal vacuum degree, so that various heat transfer paths caused by the gas are eliminated to isolate heat conduction, and the purposes of heat preservation, heat insulation and energy conservation are achieved. The vacuum heat insulating plate is a novel heat insulating material which integrates high efficiency and energy conservation, and is an upgrading product of the heat insulating material. Compared with the traditional polyurethane foam and other heat insulating materials, the vacuum heat insulating plate does not use 0DS substances in the production and application processes, has the advantages of low heat conductivity coefficient, environmental protection and energy saving, and is widely applied to the low-temperature deep cooling fields of refrigerator and freezer, refrigerator car, container, cold storage and the like and the heat insulating field of household appliance industry. When the vacuum heat insulating plate is used for a refrigerator heat insulating layer, the thickness of the vacuum heat insulating plate can be reduced to half or even less of that of a heat insulating material for a common refrigerator, so that the effective utilization space of the refrigerator is increased, and the electric energy can be saved by about 30 percent, so that the design and the manufacture of the VIP are mature at present, and most refrigerator and freezer manufacturers at home and abroad are actively developing and applying the VIP.
The internal core material of the existing vacuum insulation panel is formed by pressing, the internal part is free of a supporting structure, so that the supporting property and impact resistance of the core material are poor, bending and breaking are easy to occur, the pressing part of the core material can be separated, the use of the vacuum insulation panel is affected, and the vacuum insulation panel has no sound insulation function and cannot block the noise of a refrigerator.
