Definitions

  • the present invention relates to a construction of two or more sheets of glass which are arranged parallel to each other, for windows and/or other glass surfaces, on one or more of their surfaces provided with an extremely thin metal layer, at least one of which is disposed in an electric circuit, so that through correct disposition within the construction and through control of the power supplied, heat radiation takes place over the surface of said construction on one or both sides.
  • Such a transparent heat radiation panel is suitable for an enormously wide range of applications. Such applications can be broken down roughly into a number of groups.
  • a first application group is that where the panel separates two environments from each other and improves the heat comfort of one of those environments.
  • a second application group it is important for the panel itself to have on one or both sides a temperature which is higher than that of the outside environment.
  • the transparent heat radiation panel As double or triple window glazing for buildings.
  • the windows which traditionally act as cold surfaces and thus give rise to heat losses, contribute substantially to the improvement of heat comfort in a building or room. If there is sufficient glass surface in a room, the glazing can even act as the sole heat source.
  • An object of the invention is to produce a heat radiation panel which has a sufficiently high output for it to be used in the form of window glazing as an additional or the sole heat source for a room.
  • a transparent heat radiation panel comprising several sheets of glass, at least one glass surface of which is provided with a thin heated metal layer which is disposed in an electric circuit and is heated up by the Joule effect, is characterized by the electric power supplied to the heated metal layer in such a way that the temperature of said metal layer is between 20 and 70 deg.C, and is such that heat radiation is released at the external surfaces of the heat radiation panel.
  • the power supplied to the heated metal layer is, in other words, insufficient, through heat conduction through the section of the sheet of glass, to cause heat emission by convection at the external surfaces of the heat radiation panel. At these temperatures the metal layer does, however, continue to give off a large quantity. of heat in the form of radiation. This heat radiation leaves partially through the glass sheet carrying the metal layer to the one adjacent area and leaves partially to the other adjacent area.
  • the heat radiation panel thus radiates over its surfaces electromagnetic rays, with a wavelength of 3 to 10 microns, so that a person in the radiation area experiences a sensation of warmth.
  • the transparent heat radiation panel according:.. to the invention is further characterized by a second metal layer between the heated metal layer and one of the adjacent areas.
  • This second metal layer thereby acts as a reflecting layer which reflects the heat radiation generated by the heated metal layer and directed towards said second metal layer.
  • the part of the heat radiation which is generated by the heated metal layer and which faces away from the glass surface bearing the heated metal layer is thus reflected and joins the heat radiation which is directed through the glass sheet bearing the heated metal layer. The end result is that practically all heat radiation is released at the same external surface of the heat radiation panel.
  • This heat radiation panel is suitable for a wide range of applications.
  • the present invention is used in the form of double or triple glass as window glazing. Provided that there is a sufficiently large glass surface, this construction can fully or partially ensure an increase in or maintenance of the thermal comfort of an interior environment.
  • Aluminium the material generally used for the intermediate sections in the construction of double or triple insulating glazing, also produces a number of problems. If the heated, current-carrying metal layer and the reflecting, non-current-carrying metal layer are facing each other with their free surface, the aluminium produces direct electrical contact between the current-carrying and the non-current-carrying layer. This should, of course,. be avoided.
  • Another object of the invention is to produce a heat radiation panel which also provides a solution to these problems.
  • the heat radiation panel according to the invention comprising several sheets of glass, at least one glass surface of which is provided with a thin heated metal layer which is disposed in an electric circuit and is heated up by the Joule effect, and a second metal layer disposed against another glass surface between the heated metal layer and the outside environment, is characterized by an insulating screen, preferably made of glass, which is disposed between the two metal layers.
  • Another feature of the heat radiation panel according to the invention which is built up in the form of several glass sheets held apart by intermediate sections running along their edges, is that at least the glass surface carrying the heated metal layer, and possibly also the other glass surfaces carrying a metal layer; have stuck onto them all the way round a thin insulation strip, close to their edge, at the level of the point where the section goes when the sheets of glass are being put together.
  • Another object of the invention is to provide a contact strip which can be fitted in a simple and relatively cheap way on two opposite edges of the heated metal layer, in such a way that said metal layer can be fitted in an electric circuit.
  • the heat radiation panel according to the invention which is provided with a contact strip over the length of two opposite sides of the heated metal layer, is characterized by the contact strip which consists of an adhesive tape made of electrically conducting material, finished with a baked-in silver layer running over one or both edges of the adhesive tape from the top surface of the adhesive tape to the top surface of the heated metal layer.
  • the advantages of a heating unit made up of this heat radiation glazing are obvious.
  • the heating comfort in a room is improved by the elimination of the cold surfaces and by converting these to heat surfaces.
  • Another application of the heat radiation panel according to the invention within the same first application group is that in which several heat radiation panels are used to construct an aquarium or terrarium.
  • the advantages are obvious.
  • the water is heated up equally, no ugly heating elements need be placed in the water, and there are no safety problems like those -found with the classic water heating systems.
  • An example of the above-mentioned second application group is that where the heat radiation panel according to the invention is set up in front of, behind or around a mirror glass.
  • a mirror hung in a bathroom due to its temperature being higher than the bathroom environment, will not become steamed up when the bathroom air contains a high level of moisture.
  • Such a mirror can, however, also act as a heat source.
  • the heat radiation panel according to the invention is used as the glazing of, for example, a traffic control tower.
  • the heat radiation panel according to the invention By directing outwards all or part of the heat radiation, one prevents those windows from, for example, freezing or steaming up, so that seeing out of them is ensured in all weather conditions.
  • Double glazing separating an interior environment (11) from an exterior environment (6) is produced on the basis of two sheets of glass (1) and (2) which are disposed parallel to each other and which have a cavity (3) between them.
  • the inner glass sheet (2) bears the heated metal layer (4)
  • the outer sheet (1) bears the reflecting metal layer (5).
  • a first possibility for incorporation of the heat radiation panel according to the invention in triple glazing is to set u p a third glass sheet parallel to the outermost glass sheet (1) of the double glazing, with between them again a sealed cavity.
  • a screen which acts as a dielectric.
  • Said screen is preferably a glass sheet (23) which in the case of double glazing separating an exterior environment (6) from an interior environment (11) (Fig. 2) is placed in the cavity (3) against the free surface of the heated metal layer (4).
  • the glass sheet (23) screens off the free surface of the heated metal layer (4) in insulating fashion and thus prevents the exchange of free electrons between the heated and the reflecting metal layers (4) and (5).
  • Said glass sheet (23) also acts as an additional cooling element which, together with the innermost glass sheet (2), absorbs the heat of the heated metal layer and thus prevents the temperature of the cavity from rising too high.
  • the glass sheet (23) can be fixed against the innermost glass sheet (2) with a known tranpa- rent adhesive or with the known systems of lamination.
  • This construction can also be useful for increasing the glass thickness of a glass wall. This can be beneficial, for example, for those faces of aquaria and terraria which have to resist to a great pressure. Since glass provided with a metal layer is available only in limited thicknesses, a thick glass sheet can be stuck to one of the glass sheets bearing a metal layer, in order to increase the strength of the whole construction.
  • the additional glass sheet can be avoided by the following construction.
  • the heated metal layer (4) (Fig. 3) rests on the outside of the innermost glass sheet (2), then followed by - towards the outside - the first cavity (3) and the middle glass sheet (24) which on its outside bears the reflecting metal layer (5). This is then followed by the second cavity (3) and the outermost glass sheet (1).
  • the middle glass sheet (24) acts in this construction as a screen and as a carrier of the reflecting metal layer (5).
  • the reflecting metal layer (5) can also be set up against the inner surface of the outermost glass sheet.
  • Fig. 4 shows an arrangement which emits equal radiation on both sides.
  • a second glass sheet (32) is indissolubly joined to the bearing glass sheet (8) with the heated metal layer (4) by means of a known, transparent adhesive or by the known systems of lamination. This composition will be used in arrangements where this is necessary for safety reasons.
  • FIG. 5 Another possible arrangement of the radiation panel according to the invention is that in which the panel is incorporated in a mirror (Figs. 5 and 6).
  • a glass sheet (8) with a heated metal layer (4) is either placed against or in front of a mirror glass (33) (Fig. 5), or the mirror glass (33) is placed behind and against a glass sheet (8) with a reflecting metal layer (5), with in front of it - with a cavity (3) between - the glass sheet (8) bearing the metal layer (4) (Fig. 6).
  • said metal layer, or the bearing glass sheet must be provided with a contact strip over the length of two opposite sides. Said contact strips permit contact with one or more current-carrying cables, on the one hand, and distribute the current over the length of the heated metal layer, on the other.
  • Said contact strip (Fig. 7) comprises an adhesive tape (25), made of an electrically conducting material, which is glued and pressed onto the heated metal layer (4) along the edge of the bearing glass sheet (8).
  • the contact strip is finished with a baked-in silver paste layer (26) on one or both of its longest edges.
  • This silver paste layer (26) is spread out over the edge of the adhesive tape (25) up to the heated metal layer and is then baked in, so that the silver diffuses both in the metal of the adhesive tape (25) and in the metal layer (4), and thereby increases the electrical contact between the two metals.
  • one silver paste layer (26) is shown by a solid line
  • the possible second silver paste layer (26) is shown by a dotted line.
  • the heat radiation panel according to the invention is provided, at least over the full lengths of the edges of the glass sheet bearing the heated metal layer, and possibly over those of the glass sheet bearing the reflecting metal layer - at least if it is facing the heated metal layer - with a narrow glass strip (27) (Fig. 7) stuck against the glass sheet.
  • this glass strip (27) partially covers the adhesive tape (25) and leaves its free over a short distance of its width on the outside of the frame which the glass strips (27) form together.
  • the glass strip (27) is glued directly to the heated metal layer.
  • the glass strips (27) join together perfectly, so that they form a frame all the way round, a certain distance away from the edge of the glass sheet.
  • the metal layer For a close-fitting construction of the edges of the heat radiation panels, which is produced in the. form of double or triple glazing, or in any other form with a cavity which is to be hermetically sealed, the metal layer must be removed over a strip (29) along the edge of the glass sheet (8) (Fig. 7), in order to permit direct adhesion of the elastic sealing means to the glass.
  • a heat radiation panel according to the invention designed as double glazing, without screen looks, for example, as follows (Fig. 8).
  • the glazing separates an interior environment (11) from an exterior environment (6) and comprises from inside to outside the innermost glass sheet (2), the heated metal layer (4), the cavity (3), the reflecting metal layer (5), and the outermost glass sheet (1).
  • the adhesive tape (25) is stuck onto the heated metal layer (4). Diffused in over the top edge of said adhesive tape (25) is a silver layer (26).
  • the continuous glass strip (27) is stuck against one or both - here on both - of the glass sheet (2) and (1), against the inside at the same height.
  • the aluminium intermediate section (16) goes between these glass strips (27).
  • a sealing plug (18) Between the side edge of the intermediate section (16) and the glass strip (27) there is a sealing plug (18). Under the sealing plug (18) and the intermediate section (16) the cavity is filled with a sealing agent (19). Underneath the glass sheets (2) and (1), the metal layer is removed over a strip (29), so that the sealing agent (19) comes into direct contact there with the glass. The whole construction is finished with an aluminium clamping section (20) which encloses the two glass sheets (2) and (1) all the way round along the edges.
  • the contact on the contact strip can be made in the classic way by soldering on of the end of one or more electric cables. With the current glass measurements one contact point per contact strip is sufficient. In the case of the construction with the glass strips (27) (Fig. 7) they must be provided with a recess (30) at the place where the contact point (22) goes, so that here would be sufficient space to solder the end of the electric cable (21) onto the adhesive tape (25).
  • FIG. 9 Another possibility for making the contact on the contact strip is proposed in Fig. 9.
  • the part of the adhesive tape (25) projecting from under the screen (23) is rolled round a copper cable (21), running over the entire or part of the length of the adhesive tape (25). This means that no heat treatment is needed to obtain the contact points.
  • the whole unit may be finished with a non-conducting cover (31). It goes without saying that this form of contact is also possible in the case of the glass strips (27) (Fig. 8).
  • the heat radiation panel can be used for a large number of applications. Some of them have already been put forward here : double or triple glazing which can be used for the heat comfort of an interior environment, use in aquaria, and the fitting in a mirror. It is not, however, within the scope of this description to give an enumeration of all possible applications.
