Technical field
The utility model belongs to refrigerator manufacturing field, more particularly to a kind of vacuum heat-insulating plate and its fixed device.
Background technique
Heat-insulating shield is one of vacuum thermal insulating material, is to be combined by filling core material and vacuum protection surface layer, it has
Effect heat caused by cross-ventilation is avoided to transmit, therefore thermal coefficient can be greatly lowered, is less than 0.003w/m.k, and be free of
There is any ODS material, there is environmental protection and energy-efficient characteristic, is current efficient thermal insulation material state-of-the-art in the world.
Heat-insulating shield is mainly used for heat preservation insulation, such as domestic refrigerator, yacht refrigerator, minifridge, car refrigerator, deep cooling ice
Cabinet, electric heater, vending machine, household freezer, frozen products insulated container, construction wall heat preservation and LNG storage and transportation etc..
After long-term use, vacuum degree reduces current heat-insulating shield, the disadvantages of heat insulation and preservation effect is to be improved, and existing
Heat-insulating shield after barrier bag is damaged, core plate easily expands, so that heat-insulating shield still loses the performance of heat-insulation and heat-preservation, and is used at this stage
Heat-insulating shield not only thickness is larger, but also thermal coefficient is larger, and using effect is less desirable；The fixation of heat-insulating shield is most simultaneously
Refrigerator inner wall is fixed on by glue or double surface glues, it has not been convenient to dismounting maintenance, if being also easy failure using overlong time glue
Heat-insulating shield is caused to fall off, so that heat insulation effect is unobvious.
