Description

HEAT INSULATING SHEET UNIT FORMING AN INSULATING
GLASS CONTAINING AEROGRAPHITE
The present invention refers to an insulating sheet, which comprises at least two sheets separated of at least one there between situated spacer element, which encloses at least one space, which in turn encloses at least one gas. In at least one portion of said space nanoparticles are brought, which decreases a gas circulation between the sheets when a portion of the gas is heated in order to improve the heat insulation capacity of the heat insulating sheet unit.
Existing structures on the market of this kind, where you heat insulate using rockwool, glass wool and insulating glass, where quantities of air are enclosed in smaller spaces or as in an insulating glass a number of glass sheets enclose air volumes in order to decrease the air circulation, which transfers heat via convection through said insulating glass. A number of glass sheets are expensive and heavy in an insulating glass in order to receive good heat insulation. In order to further improve the heat insulation low emission layers are used on at least one inside of the glass sheets in order to reflect in heat radiation into a heat isolated space. It is expensive and time consuming. These insulating glasses still have a bad heat insulation compared to an ordinary insulated wall, which has about three times better heat insulation.
The object of the present invention is to eliminate the drawbacks existing with the above mentioned structures, by decreasing the convection in a heat insulating sheet unit by that more or less fill that space existing between the sheets by Aerographite, which consists of a network of carbon nanotubes and air.. Aerographite consists mainly of air. Aerographite can carry 40 000 times its own weight and if the material is squeezed together it springs back to its original form. This makes that the convection decreases drastically in an insulation glass, which drastically improves its heat insulating capacity. Thanks to the present invention one has now provided a device in a heat insulation sheet unit, which has at least two sheets, preferably glass sheets, which are separated of spacer elements lying there between, which enclose at least one space, said space encloses at least a gas in order to constitute for example an insulating glass. According to the invention the space is filled up with Aerographite, which touches upon and fills up the space of the insulating glass between them and mainly prevents gas circulation between said sheets, when a portion of the gas is heated. In this case mainly no convection will start, why only very little of said heated gas can via the convection be transported through the insulation glass, which in this case obtains a strongly improved heat insulating capacity. The carbon nanotubes are so small that they have a size, which is invisible for the naked eye. In order to provide as good heating insulation as possible each carbon nanotube extends against each other and supports each other. In this way the convection is stopped more effective, especially if they have extensions, which hook up to each other in the space. In one version of the invention Aerographite has sparsely arranged, elongated carbon nanotubes. In this way a great extension is obtained in relation to its weight of each nanoparticle, which increases its light permeability, which is good in an insulating glass in order to get the light indoors. Thanks to that the carbon nanotubes are made of a light and/or heat reflecting material, which reflects back energy into a heated space, which is heat insulated, said heat insulating quality can be further improved in order to reflect radiating heat from a heated space back to the same.
The invention is described closer below by help of some preferred embodiment examples with reference to the drawings enclosed, in which
Fig. 1 illustrates a sheet unit such an insulating glass, and
Fig. 2 illustrates a number of carbon nanotubes connected together . As can be seen from fig 1, a heat insulating sheet unit 1 is illustrated, which comprises two glass sheets 2 in the form of glass sheets 3, separated by a spacer element 4 lying between enclosing a space 5, which in turn encloses an Aerographite 6, constituting for example an insulating glass 7. The space 5 is filled up with carbon nanotubes 8, which prevent a gas circulation between the sheets 2.
As can be seen from fig. 2 there is illustrated that the carbon nanotubes 8 have extensions 9, which hook up to each other. The carbon nanotubes 8 have open provided, elongated nanoelements 10, which said carbon nanotubes are built up from in order to achieve a large extension in relation to their weight. The carbon nanotubes 8 consist of some light and/or heat reflecting material 11, which reflects back energy into a heated space indoors, which is heat insulated .
