Definitions

  • the present invention relates to a spacer profile for a spacer frame of an insulating pane unit, which is to be attached in the edge region of at least two spaced-apart panes to form a space between the panes, the profile body of the spacer profile consisting of poorly heat-conducting material and with a side facing away from the pane space in the installed state is connected across its entire width diffusion-tight layer of good heat-conducting material.
  • the panes of the insulating pane unit are normally glass panes made of inorganic or organic glass, but the invention is not restricted to this.
  • the panes can be coated or refined in some other way to give the insulating pane unit special functions, such as increased thermal insulation or soundproofing.
  • the profile body of the spacer profile made of poorly heat-conducting material comprises the bulk of the main part of the spacer profile and gives it its cross-sectional profile.
  • the thermal conductivity values ⁇ are typically on the order of 5 W / (m ⁇ K) and below, preferably they are less than 1 W / (m ⁇ K) and more preferably less than 0.3 W / (m ⁇ K). Plastics will usually fall under this definition.
  • the diffusion-tight layer will normally be cohesively connected to the profile body at least in some areas.
  • cohesively connected it is meant that the profile body and the diffusion-tight layer are permanently connected to one another, for example by co-extruding the profile body with the diffusion-tight layer or by laminating the diffusion-tight layer on separately, if necessary using an adhesion promoter or similar techniques.
  • spacer frames The most important tasks of spacer frames are to keep the panes of an insulating pane unit at a distance, to ensure the mechanical strength of the unit and to protect the space between the panes from external influences.
  • heat transfer characteristics of the edge bond and thus of the spacer frame. the spacer profile from which it is made requires special attention.
  • a deterioration in the thermal insulation of an insulating pane unit in the edge area, in particular due to conventional metal spacers, has been documented several times.
  • the increased heat conduction in the area of the edge bond due to the formation of condensation on the edge of the inner pane at low outside temperatures is clearly visible.
  • the general aim is to keep the temperature in the area around the edges of the inner pane as high as possible. Developments in this direction have become known as "warm edge" techniques.
  • plastic spacer profiles have also been used for a long time in order to take advantage of the low thermal conductivity of these materials.
  • materials of this type generally have a low diffusion tightness in comparison to metal.
  • spacer profiles made of plastic special measures must therefore be taken to ensure that ambient air does not penetrate into the space between the panes to such an extent that the absorption capacity of the desiccant usually accommodated in the spacer profiles will soon be exhausted and the functionality of the insulating pane unit will be impaired.
  • a spacer profile must also prevent filling gases, such as argon, krypton, xenon, sulfur hexafluoride, from escaping from the space between the panes. Conversely, nitrogen, oxygen, etc. contained in the ambient air should not enter the space between the panes. Insofar as diffusion tightness is mentioned in the following, this means both vapor diffusion tightness and gas diffusion tightness for the gases mentioned.
  • DE 33 02 659 A1 which was used to form the preamble of claim 1, proposes to provide a spacer profile made of plastic with a vapor diffusion-tight layer (vapor barrier) by pressing on the profile body made of plastic on that side faces away from the space between the panes in the installed state, a thin metal foil or a metallized plastic foil is applied. This metal foil must span the space between the panes as completely as possible so that the desired vapor barrier effect occurs.
  • the diffusion-tight metal foil must be arranged on the side of the spacer profile facing away from the space between the panes in the installed state, so that desiccant located in the spacer profile is only in gas-conducting connection with the space between the panes, but not with the surroundings of the pane.
  • the disadvantage here is that the metal foil forms a path of high thermal conductivity from one pane of the insulating pane unit to the other. The effect of reducing the thermal conductivity of the edge bond achieved by using a plastic as a profile material is thereby considerably reduced.
  • spacer profiles made of poorly heat-conducting material have been developed in which the path of high thermal conductivity formed by the metal foil from one disk to the other has been deliberately extended.
  • Such a spacer profile was presented under the name THERMOPLUS® TIS, for example in the brochure "Impulses for the future" of Flachglas AG and is described in the older German utility model 298 14 768 U1.
  • the plastic profile body of this spacer profile comprises a desiccant chamber for receiving hygroscopic materials, with contact webs being provided on both sides of the chamber for abutment on the inside of the pane, which are connected to the desiccant chamber via bridge sections.
  • the profile On the outside facing away from the space between the panes in the installed state, the profile is provided with a reinforcing layer which simplifies corner bending and also ensures diffusion tightness.
  • the path of high heat conduction formed by the diffusion-tight layer has been made much longer than the width of the space between the panes due to its meandering course.
  • the length of the diffusion-tight layer normally formed by a metal foil is up to four times the width of the space between the panes or more, as a result of which the heat conduction from one pane to the other is considerably reduced by the spacer profile.
  • the known spacer profile has a profile body formed from two metallic half-shells, the two half-shells enclosing a core made of poorly heat-conducting material, in which a desiccant is embedded.
  • the metallic half-shells have a thickness that is customary in the case of metallic spacers and consist, for example, of highly thermally conductive aluminum.
  • the solid polymer core breaks through the metallic profile body both on the side facing the space between the panes and on the outside thereof, so that there the metallic half-shells are spaced several millimeters apart.
  • the known spacer profile is not sufficiently diffusion-tight due to its construction. Due to the relatively large material thickness of its profile body made of highly heat-conductive aluminum, its thermal engineering data are also unsatisfactory.
  • EP 0 852 280 A1 discloses a spacer profile with the features of the preamble of claim 1.
  • the poorly heat-conducting material here consists of glass fiber reinforced plastic, which is connected to a diffusion-tight metal foil over its entire width.
  • FR-A-2 571 775 A1 relates to a metal profile for a fire-retardant window beam, which has a notch as a thermally insulating zone.
  • the diffusion-proof layer has at least one region extending in the longitudinal direction of the spacer profile with reduced heat conduction transversely to the longitudinal direction of the spacer profile.
  • the area with reduced heat conduction means a section of the diffusion-tight layer in which its heat conduction is reduced in comparison to its adjoining sections.
  • the area with reduced heat conduction can be formed by a line-shaped recess which partially penetrates the diffusion-tight layer in its thickness direction, for example in the form of an indentation which is approximately triangular in cross section.
  • the area with reduced heat conduction is, however, formed by a linear recess which completely interrupts the diffusion-tight layer in its thickness direction. This avoids direct heat transfer between the ends of the diffusion-tight layer adjacent to the recess.
  • the line-shaped recess of the diffusion-tight layer can be formed as an uninterrupted continuous line (notch, slot) or as a series of line-shaped perforations.
  • a bead made of a diffusion-tight, poorly heat-conducting material.
  • a suitable material for such a bead is an isobutylene-based butyl sealant, which is usually used to glue the spacer profile to the inside of the pane of the insulating pane unit.
  • the area with reduced heat conduction can also be formed in the diffusion-tight layer by arranging a strip-shaped insert made of another material which is also less heat-conductive than the material of the diffusion-tight layer and is also diffusion-tight.
  • the area with reduced heat conduction can also be formed by physical or chemical modification of the diffusion-tight layer along a strip-shaped area, for example by area-wise oxidation, material removal or a porosity treatment.
  • the diffusion-tight layer is preferably arranged on the surface of the profile body facing outward in the installed state or at least partially embedded in the profile body near it.
  • the diffusion-tight layer preferably consists of a material, in particular a metal, with a thermal conductivity ⁇ 50 50 W / (m ⁇ K). Suitable materials are, for example, stainless steel or chromed or tinned iron sheet.
  • the thickness of the diffusion-tight layer should be at least 0.02 mm.
  • the diffusion-tight layer made of tinned iron sheet (tinplate) or chrome-plated iron sheet has a thickness of less than 0.2 mm, preferably at most 0.13 mm, while in the case of a diffusion-tight layer made of stainless steel a thickness of less than 0.1 mm, preferably at most 0.05 mm, is desirable.
  • the poorly heat-conducting material of the profile body can be a thermoplastic material with a thermal conductivity of ⁇ ⁇ 0.3 W / (m ⁇ K), such as polypropylene, polyethylene terephthalate, polyamide or polycarbonate.
  • the profile body has a hollow chamber for receiving desiccant and the diffusion-tight layer is arranged on the side of the hollow chamber facing away from the space between the panes in the installed state.
  • the profile body also has contact webs for contacting the inside of the panes, which are connected to the side walls of the hollow chamber via bridge sections.
  • the invention succeeds in a surprisingly simple manner in the case of spacer profiles with a profile body consisting of poorly heat-conducting material, which can have different cross-sections and which is connected to a diffusion-tight layer of good heat-conducting material, reducing its heat transfer from one pane to another and at the same time maintain good diffusion tightness.
  • FIGS 1 to 4 show cross-sectional views of spacer profiles according to the invention. Apart from tolerances caused by manufacturing technology, the cross section does not normally change over the entire length of the spacer profile.
  • the drawings are only shown schematically, in particular the proportions of the diffusion-tight layer in comparison to the spacer profile are not to scale.
  • the profile body for example made of black-colored polypropylene Novolen 1040 K, comprises an inner wall 12, which in the installed state faces the space between the panes, two contact walls 20 and 22 intended for contact with the inside of the panes, and a rear wall 18 adjoining them over short transition areas mm 12 thick walls 12, 18, 20, a drying agent chamber 10 is defined, which will later be filled with hygroscopic material. So that moisture can enter the desiccant chamber 10 from the space between the panes, 12 through openings 50 are provided in the inner wall.
  • the system walls 20 and 22 are each provided with an indentation 90 in its surface intended for contact with the inside of the pane, which begins at a certain distance from the ends of the contact walls 20, 22 facing the pane space and extends over the entire remaining area thereof.
  • the profile form described is the subject of the unpublished German utility model application 298 07 418.4, the content of which is referred to to avoid repetition.
  • a diffusion-proof metal layer 40 made of 0.125 mm thick chromed iron plate provided with an adhesion promoter layer, which is integrally connected to the profile body.
  • Such a diffusion-tight layer is the subject of the unpublished German utility model application 298 07 413.3, to which reference is also expressly made.
  • the depth of the indentation 90 corresponds exactly to the thickness of the diffusion-tight metal layer 40, so that the contact surface formed by the profile body and the contact surface formed by the diffusion-proof metal layer 40 lie exactly in one plane.
  • the diffusion-tight metal layer 40 has a notch 42 about 0.5 mm wide on the outside, approximately in the region of the longitudinal center plane of the spacer profile, through which a line-shaped region with reduced heat conduction is formed.
  • FIG. 2 The embodiment of a spacer profile according to the invention shown in FIG. 2 is based on a profile body according to the German utility model DE 298 14 768 U1.
  • a desiccant chamber 10 is defined by walls 12, 14, 16, 18, the connection between this chamber 10 and the space between the panes being established via passage openings 50 or the like.
  • Certain abutment webs 30 and 36 are connected to the chamber 10 via bridge sections 32 and 34 for abutment on the inside of the pane, the abutment webs 30, 36 each having an indentation 90 in their surfaces facing the inside of the pane in the installed state, into which a diffusion-tight Layer 40 of a 0.13 mm thick tinplate film is inserted.
  • the diffusion-tight layer 40 extends essentially from the contact surface of the first contact web 30 around it to the bridge section 32, then around the chamber 10 to the bridge section 34 and around the contact web 36 up to its contact surface.
  • the diffusion-tight layer 40 is completely interrupted linearly in its thickness direction approximately in the area of the longitudinal center plane of the spacer profile.
  • the width of the interruption 42 is in the range from 0.1 mm to 1 mm.
  • the interruption 42 is covered with a bead 80 with a diameter of approximately 3 mm made of a diffusion-tight material that is only slightly thermally conductive.
  • a material can be, for example, an isobutylene-based butyl sealant, which is usually also used for gluing the contact webs to the inside of the pane of the insulating pane unit.
  • the embodiment of the spacer profile according to the invention according to FIG. 3 differs from that according to FIG. 2 only in that, in addition to the first one arranged in the longitudinal center plane of the diffusion-tight layer 40
  • Interruption 42 two further interruptions 44 and 46 running parallel to it are provided, which also extend linearly on both sides of the first interruption 42. It has been found that the thermal insulation of a spacer profile can be further improved if, instead of an interruption of a predetermined width, several interruptions 42, 44, 46 are provided in the diffusion-proof layer 40, the overall width of which corresponds approximately to the width of the simple interruption. In this example, the three interruptions 42, 44, 46 are each designed with widths of 0.1 mm. In particular, reference is made to the exemplary embodiments in connection with FIG. 8.
  • FIG. 4 Another embodiment of a spacer profile according to the invention is shown in Figure 4.

  • the thickness of the diffusion-tight layer 40 in the area of the outer wall 18 of the chamber 10 is reduced to such an extent compared to the thickness of the diffusion-tight layer in the area of the contact webs 30, 36 that there is just sufficient diffusion-tightness of the spacer profile in this area, or it is a corresponding strip-shaped insert 48 is provided.
  • the diffusion-tight Layer 40 in the area of the contact webs 30, 36 of the spacer profile on the other hand, has a significantly higher layer thickness, with which a bending behavior in the sense of DE 298 14 768 U1 can be achieved.
  • FIG. 5a shows, partially cut away, a view of a spacer profile according to the invention in the installed state from the outside, that is to say shows a plan view of the diffusion-tight layer 40 with the area designed as an interruption 60 with reduced heat conduction.
  • the interruption 60 is shown here as
  • Slit pattern is formed, which prevents the diffusion-proof layer 40 from tearing when the spacer profile is bent or peeling off from the poorly heat-conducting material of the profile body.
  • FIG. 5b shows an area designed as a hole pattern 62 with reduced heat conduction.
  • FIG. 6 shows the detailed view of an embodiment of the invention, in which the area with reduced heat conduction is formed by a linear recess in the form of a notch 70 which only partially penetrates the diffusion-tight layer 40. Due to the local reduction in thickness in the area of the notch 70, the heat transfer of the diffusion-tight layer 40 transversely to the longitudinal axis of the spacer profile is significantly reduced compared to a diffusion-tight layer 40 with a constant thickness, while the diffusion-tightness remains almost unchanged.

  • the light-colored bars indicate the temperature when using the spacer profiles with a metal foil, which has a continuous, linear interruption of 0.3 mm in width in the middle in the profile longitudinal plane as an area with reduced heat conduction, while the hatched bars indicate the temperature when using a metal foil with three parallel, also continuous, line-shaped interruptions of width 0.1 mm, the two outer interruptions being spaced 3 mm apart from the central interruption arranged in the longitudinal plane of the profile.
