Abstract
The utility model relates to the improvement for a vacuum thermal insulation plate and a refrigerator thermal insulation layer, which is characterized in that the vacuum thermal insulation plate is pumped into vacuum after an aluminum foil seal bagging is provided-in ultra-fine fibre glass cotton in the form of compacted layer. Compared with the existing vacuum thermal insulation plate, the utility model has lower thermal conductivity factor of some 0. 0025 which is 1/10 of the original foamed layer thermal insulation layer of the refrigerator, so that the performance of thermal insulation can be visibility improved without increasing the thickness of the thermal insulation layer. Moreover, the thermal insulation plate has convenient manufacture, easy shaping and light weight. The energy conservation refrigerator formed by placing the vacuum thermal insulation plate in the foamed layer of the refrigerator has the advantages of good performance of thermal insulation and heat preservation, short operating time of a compressor, so that the daily amount of using electricity can be obviously reduced, and the effect on energy conservation is obvious.
Description
Technical field
Utility model is about the improvement to vacuum insulation panel and refrigerator lining.
Background technology
Be to reduce the energy resource consumption of modular refrigerating appliances such as refrigerator, refrigerator-freezer, selecting high performance heat-barrier material is that people pursue always, and vacuum insulation panel is because of having heat-proof quality preferably, and is adopted by people.Therefore multiple vacuum insulation panel arises at the historic moment, as Chinese patent 99811986.5 disclosed refrigerator vacuum heat-insulating plates, be by a plurality of comprise than under atmospheric equilibrium in it water content lack the metal oxide briquetting, be enclosed in and stop in the film that moisture passes, be evacuated then.What this vacuum insulation panel adopted is metal oxide such as Cab-O-sil, not only make comparatively complexity, and weight is big relatively.Chinese patent 98813041.6 disclosed vacuum insulation panels still adopt the plate core of porous or open-celled rigid matrix of materials, and its air-gap is more relatively, influences heat-proof quality.Therefore still having is worth improved place.
Summary of the invention
The purpose of utility model is to overcome the deficiency that above-mentioned prior art exists, and provides a kind of simple for production, in light weight, and thermal conductivity factor is low, the refrigerator vacuum insulation panel of good heat-insulation effect.
Another purpose of utility model is to provide a kind of above-mentioned heat insulation energy-saving refrigerator of making thermal insulation layer that utilizes.
The utility model purpose realizes that main the improvement is to select for use the ultra-fine fibre glass cotton of low thermal conductivity to make built-in thermal insulation layer, adopts aluminium foil to vacuumize the cladding bag, thereby makes the vacuum heat-insulation plate that makes have lower thermal conductivity factor.Specifically, the refrigerator vacuum insulation panel comprises air-locked encapsulation bag and built-in thermal insulation layer, and said encapsulation bag is pumped into vacuum after placing thermal insulation layer, it is characterized in that said encapsulation bag is the aluminium foil film, and said built-in thermal insulation layer is for compressing stratiform ultra-fine fibre glass cotton.
For effectively improving heat preservation and insulation, the said built-in thermal insulation layer of utility model to adopt multilayer (multi-disc) structure, helps reducing thermal conductivity factor especially.The ultra-fine fibre glass cotton compresses, and not only helps placing more ultra-fine fibre glass cotton, and is pumped into sky easily.Utility model can also be covered with heat-reflecting layer in the aluminium foil bag inboard in addition, with further raising effect of heat insulation.
Utility model second purpose realizes, be that above-mentioned vacuum insulation panel is used for refrigerator lining, thereby constitute heat loss energy-saving refrigerator still less, for making the vacuum insulation panel can be in aggregates with refrigerator shell, strengthen bulk strength, reduce the space, vacuum insulation panel can be positioned in the refrigerator shell, fuse by existing foaming layer and refrigerator shell on its two sides again.
The utility model vacuum insulation panel, owing to adopt the heat insulation and better aluminium foil bag of pliability, and the low ultra-fine fibre glass cotton of thermal conductivity factor, cracky not when vacuumizing, long service life, be laminated with heat-reflecting layer at encapsulation bag inner surface, more help improving its heat-proof quality, the thermal conductivity factor of its plate is about 0.0025 only, is 1/10th of the former foaming layer thermal insulation layer of refrigerator, therefore can significantly improve heat preservation and insulation not increasing thermal insulation layer thickness.And this thermal insulation board convenient processing and manufacture, moulding easily, in light weight.Multilayer insulation cotton knot structure more can lower the conduction of fiber heat, further reduces thermal conductivity factor.Adopt this vacuum insulation panel to be placed on the energy-saving refrigerator of forming in the refrigerator foaming layer, heat preservation and insulation is good, and the compressor operating time is short, and daily power consumption obviously reduces, and energy-saving effect is obvious.
The said vacuum of utility model is not the finger absolute vacuum, and is meant air is wherein taken out as far as possible, does not have the vacuum state that air is deposited substantially and become.
