Description
Technical field
The present invention relates to a kind of environmental protection heat-barrier material, especially a kind of dual-layer high vacuum metal heat preservation sheet.
Background technology
In the epoch of paying attention to environmental protection and energy saving, the heat-insulation and heat-preservation of building is more and more paid attention in the whole world, and to save the use of air-conditioning and heating installation, energy conservation reduces discharging.Existing heat insulating material adopts nonmetals more, and intensity is low, can't keep very high vacuum, can not accept simultaneously shortcomings such as long-time sunlight exposure, heat insulation inefficiency, can't widespread adoption in building field.
Summary of the invention
The objective of the invention is to provide a kind of high strength, high-effect, dual-layer high vacuum metal heat preservation sheet that the life-span is long.
The present invention is achieved in that dual-layer high vacuum metal heat preservation sheet, it is characterized in that comprising the metal base plate and the metal decking of edge welded seal, and described metal base plate is provided with brace and hook, and the place of keeping to the side is provided with encapsulated holes.
Therefore metal base plate and metal decking form cavity at edge's welded seal.It is above with deaeration by vacuum brazing furnace the cavity vacuum degree to be brought up to 10-2Torr to 10-4Torr (an atmospheric pressure 760Torr), and the high temperature melting cored solder encapsulates encapsulated holes in addition, the while activated degasser, absorb the inert gas that metal sheet itself discharges, finally realize the high vacuum between the bilayer.
Metal base plate and metal decking can be square or circular; Under the square situation, brace and hook are positioned at four jiaos, and under the circular situation, brace and hook are positioned at the center.Brace is used for junction plate face and hook.In order to gain in strength, can also on the plate face, reinforcing rib be set.
The metal base plate place of keeping to the side is provided with encapsulated holes, air by between vacuum brazing furnace eliminating metal base plate and the panel utilizes the high temperature melting cored solder that encapsulated holes is encapsulated simultaneously, and activated degasser, the final high vacuum that realizes between the bilayer, thus reach the cool maximum effect of warming guarantor.
Be provided with getter standing groove (the porose inner chamber that leads to, getter can be blocked this hole to guarantee inner chamber vacuum) at the metal base plate place of keeping to the side, to absorb the inert gas that metal sheet itself discharges in the inner chamber.
Because the energy in the transfer that temperature contrast causes is called conduction of heat.In other words, when having temperature difference to exist in a medium or between second medium, must there be conduction of heat to take place.Conduction of heat as a rule has 3 patterns:
1. conduction of heat (directly conduction): contact the conduction of heat that is taken place via solid or liquid (static fluid).
2. thermal convection current (convection current conduction): gas flow changes the conduction of heat that is produced.
3. heat radiation (radiation conduction): the conduction of heat that heat radiation produced on two articles surface, heat radiation system does not need any media heat energy can be released in the environment with the form conduction of fluctuation (cannot see so human body is belonged to infrared rays).With straightline propagation, the shallow more transmission (just reflection is good more) that more can stop radiation of the smooth more color in surface.
The present invention is by making a kind of metal device of dual-layer high vacuum, at utmost reduced the transfer of heat that heat transmission that conduction of heat and cross-ventilation cause causes, utilize the smooth speciality in metal surface simultaneously, reduce the heat loss that heat radiation causes, reduce coefficient of thermal conductivity at last significantly.
Building utilizes this invention, can also guarantee the best cool effect of warming guarantor when reducing wall thickness greatly, since the heat-insulating property of high vacuum, the common thermal insulation material of will being better than far away after all.
The technical solution adopted in the present invention is used for the heat transmission between the isolated to greatest extent building and the external world, reduces energy waste:
1. double-decker: block conduction of heat (directly conduction), by double-decker, ectonexine separately blocks the conduction of heat of a part.
2. vacuumize: the air between the bilayer is extracted into 10-2Torr to 10-4Torr, reaches high vacuum state, block thermal convection current and conduction (media flow changes the conduction of heat that is produced between the gas)
3. metal is because of having high reflectivity.So by the copper facing of vacuum one side, or wrap up in Copper Foil and aluminium foil at internal layer, reduce the heat that radiation effects causes and scatter and disappear.
4. the use of high temperature encapsulation and getter: it is above with deaeration by vacuum brazing furnace vacuum to be brought up to 10-2Torr to 10-4Torr (an atmospheric pressure 760Torr), and the high temperature melting cored solder encapsulates encapsulated holes in addition, the while activated degasser, absorb the inert gas that metal sheet itself discharges, finally realize the high vacuum between the bilayer.
Mounting method of the present invention is as follows:
1. with vertical direction skeleton is installed on body of wall, the skeleton material is a metal, utilizes setscrew to fix;
2. by hook, the present invention is hung on the skeleton successively.Square direct tiling.Circular have a dual mode: a kind of is that roundlet is placed the great circle gap, and two kinds is that middle circle places the great circle gap and overlaps.
In sum, the present invention adopts double-layer metal material, the vacuum heat-insulation technology, and trap heat transmission to greatest extent, to save energy consumption, simple in structure, durable in use.
