Abstract
The utility model provides a vacuum heat insulating plate which comprises a casing and a heat insulating core material arranged in the vacuum casting, wherein the core material comprises silicon dioxide aerogel and glass fiber; the glass fiber is interleaved among the silicon dioxide aerogel; the surface of the core material are provided with an infrared reflecting layer; the casing is a laminated bag or hard metal or a glass plate. The silicon dioxide aerogel is adopted as the main core material for the heat insulating material which has the advantages of large hardness of the material after the vacuum forming, difficult breaking and more flexible processing and using.
Description
Technical field
The utility model relates to a kind of thermal shield, is specifically related to a kind of vacuum heat-insulating plate.
Background technique
The tradition thermal shield uses glass fibre, the glass face, polyurethane foam, foamed styrene, above-mentioned thermal shield has lower thermal conductivity, heat-insulating property is better, but the specific industry that adopts is as electrical equipment such as refrigerator, electric water heater cold insulation or heating plant etc., often need bigger thickness, thickness increases the volume that causes electrical equipment and becomes big, effectively utilize the space to reduce, for these reasons, someone has proposed vacuum heat-insulating plate, vacuum heat-insulating plate can reduce the thermal conductivity of existing thermal shield greatly, usually more than 5 times, therefore under adiabatic equal requirement of electrical equipment, can effectively reduce the thickness of thermal shield, increased accordingly adopt vacuum insulation panel products and equipment effectively utilize the space.
Existing vacuum heat-insulating plate has two kinds of structures usually, one for being provided with the adiabatic core that laminated glass fiber or glass wool form in stacked bag, with the vacuum pumping of stacked bag, and in stacked bag, adsorbent is set, improve degree of vacuum in the stacked bag, under the above-mentioned thermal shield situation identical with original antivacuum heat insulating effect, can significantly reduce the thickness of heat insulation layer, but, because the core in the stacked bag is soft glass fibre of matter or glass face, therefore the thermal shield moulding is poor, when being processed into the heat insulation layer of electrical equipment or equipment, further moulding, and the slit is big between glass face or the glass fibre, and the little air in the stacked bag still can flow at it and carry out transmission of heat.For addressing the above problem, someone proposes and the invented a kind of thermal conductivity thermoinsulation material at the end more, aerosil, this aerogel is the porous silica structure, as Chinese patent 96192192 disclosed structures, the narrow and small complications in slit between structure, inlet air flow path is long, thermal conductivity further lowers with respect to original thermoinsulation material, with the core body of aerosil as vacuum heat-insulating plate, the effect of thermal shield further improves, but aerosil matter is crisp, therefore less external force can make its fragmentation after being processed into vacuum heat-insulating plate, transports and is processed in the process of electrical equipment or equipment and all can destroy its original structure.
Summary of the invention
The problem that the utility model exists at above-mentioned aerosil vacuum heat-insulating plate, a kind of vacuum heat-insulating plate of architecture advances is provided, and this thermal shield adopts aerosil as main core, and hardness is big after the material vacuum forming, unsuitable broken, processing and use are more flexible.
For realizing goal of the invention of the present utility model, the utility model has adopted following technical proposals.
A kind of vacuum heat-insulating plate comprises stacked bag and the adiabatic core that is arranged in the stacked bag, it is characterized in that:
Described core comprises aerosil and glass fibre, and described glass fibre is interwoven between the aerosil.
In the technique scheme, in course of working, glass fibre interweaves in aerosil, can strengthen the intensity of above-mentioned core greatly, adopt the vacuum heat-insulating plate of this materials processing, thermal conductivity is low, and intensity is big, can be processed into different shape according to demand easily, be used for the processing of electrical equipment or equipment.
In the core glass fibre weight percentage select usually the position be 5～15%, aerosil weight percentage 5～95%.
The transmission of heat of core is mainly undertaken by 4 kinds of modes in the thermal shield, and 1, solid conduction, aerogel itself; 2, gas conduction, residual gas in the vacuum; 3, cross-ventilation conduction, residual gaseous exchange in the vacuum; 4, radiation conduction.Under vacuum condition, adopt aerosil as thermal shield can be above-mentioned 1,2,3 kind of heat exchange pattern reduced to very lowly, is the thermal conductivity that further reduces above-mentioned vacuum heat-insulating plate, the raising insulation effect, the surface of described core is provided with infrared reflecting layer.
Therefore infrared reflecting layer can further reduce transmission of heat with being positioned at the most of reflection of heat of the inside and outside infrared rays conduction of heat insulation layer, improves insulation effect.
Common described core thickness is 0.5～2.5cm.
Described infrared reflecting layer is 0.1～5 micron.
Described shell can be hard metal or glass plate, with the intensity of further assurance thermal shield.
For making things convenient for the moulding of vacuum heat-insulating plate, and be applied to equipment more neatly, in the plate shell that vacuum heat-insulating plate is arranged at refrigerator or water heater, as the shell of electrical equipment, described shell is stacked bag.Stacked bag be non-hard material, so easy-formation more.
Stacked bag can adopt various scheme of the prior art, as bread and cheese vacuum packaging bag, Chinese patent 00119979 disclosed technological scheme.
Preferably: described stacked bag is respectively nylon layer, polyester layer, aluminium foil layer and polyethylene layer from inside to outside from core.Above-mentioned stacked bag has the effect of reinforcing, sealing, reflecting heat and light, to strengthen insulation effect.
In the utility model, the glass fibre that interweaves in aerosil can strengthen the intensity of above-mentioned core greatly, adopt the aerospace thermal-insulated plate of this materials processing, thermal conductivity is low, and intensity is big, can be processed into different shape according to demand easily, be used for the processing of electrical equipment or equipment; For further reducing the thermal conductivity of above-mentioned aerospace thermal-insulated plate, improve insulation effect, the surface of core is provided with infrared reflecting layer.
