Definitions

  • the present invention relates to a spacer profile for use in insulating disk units having such a spacer profile.
  • Insulating disk units having at least two disks spaced apart in the insulating disk unit are known.
  • Insulating washers are usually made of inorganic or organic glass or other materials such as Plexiglas.
  • the spacing of the discs is normally ensured by a spacer frame formed of at least one spacer profile. Spacer profiles should have good thermal insulation.
  • the spacer frame is preferably bent in one piece so that, after bending, it is to be closed at a location of the spacer frame by means of a connector.
  • the disc space is preferably filled with an insulating inert gas such as argon, krypton, xenon, etc.
  • the filling gas should not be able to escape from the space between the panes.
  • it should of course also in the ambient air contained nitrogen, oxygen, water, etc., not be possible to enter the space between the panes. Therefore, the spacer profile must prevent this diffusion. Spacer profiles therefore have a diffusion barrier layer which seals the space between the panes and the environment.
  • the term "diffusion-tightness" with respect to the spacer profile or materials forming the spacer profile in the following description means both vapor-diffusion-tightness and gas-diffusion-tightness for the gases in question.
  • Insulating disk units which ensure high thermal insulation in the edge bond, meet the so-called "warm edge” conditions according to the meaning of the term in the art.
  • the WO 2006/027146 A1 shows a spacer profile for a spacer frame with a profile body made of plastic, the at least one chamber for receiving hygroscopic Has material and in which a metal foil surrounds the profile body on three sides such that in the assembled state of the spacer profile, the non-enclosed inside of the profile body to the space between the panes and this unenclosed inside of the profile body openings for moisture exchange of recorded in the chamber desiccant and the space between the panes and at in that the metal foil has a profile with at least one edge or bend at the ends facing the space between the panes.
  • the reinforcing layer may be provided to be thinner than the diffusion barrier layer but having a correspondingly higher strength and / or a correspondingly higher modulus of elasticity.
  • less heat is transferred by the comparatively thinner reinforcement layer.
  • the productivity of the bending process is directly related to the bending speed, ie the angular velocity at which the profile is moved around the bend radius.
  • the bending speed is limited in spacer profiles to a maximum bending speed, which results from the fact that longer profile sections when bending at longer intervals From the bending radius are accelerated very strong and it comes when exceeding the maximum bending speed to unwanted deformations.

Furthermore, the slack is significantly reduced, since the curved, angled and / or folded profile or Extension portion significantly contributes to the strength of the structural integrity of the curved spacer frame.
  • Fig. 12a and b) show a spacer profile according to a tenth embodiment in a W and a U configuration.
  • the profile body 10 of the spacer profile according to the ninth embodiment corresponds to the profile body 10 of the second embodiment.
  • the material of the diffusion barrier layer 30, for example, corresponds to the material of the diffusion barrier layer 30 of the second embodiment and has, for example, the same first tensile strength R1 and the same second elastic modulus E2.
  • the second tensile strength R2 and / or the third elastic modulus E3 of the material of a reinforcing layer 40d is equal to the first tensile strength R1 and / or the second elastic modulus E2 of the diffusion barrier layer 30.
  • the first thickness (material thickness) d1 of the diffusion barrier layer 30 is smaller than a second thickness d2d of the reinforcing layer 40d.
  • the profile body 10 has additional openings 15 which extend through the inner wall 13 and the reinforcing layer 40d. Thereby, the moisture exchange through the inner wall 13 can be improved.
  • Fig. 13a ) and b) show a spacer profile according to an eleventh embodiment in a W and a U configuration.
  • the spacer profile according to the eleventh embodiment is different from the spacer profile of the tenth embodiment in that a diffusion barrier layer 30e is formed in the outer wall 14 and in the sidewalls 11, 12. It is advantageous if the diffusion barrier layer 30e is arranged centrally in the outer wall 14 and the walls of the profile body 10 uniformly surround the diffusion barrier layer 30e.
  • the features of the different embodiments can be combined freely with each other.
  • the product of the second tensile strength R2 and the second thickness d2, d2a, d2b, d2c, d2d is greater than the product of the first tensile strength R1 and the first thickness d1, d1a, d1b, d1c, d1e.
  • product of the third elastic modulus E3 and the second thickness d2, d2a, d2b, d2c, d2d is always larger than the product of the second elastic modulus E2 and the first thickness d1, d1c, d1e.
  • the reinforcing layer shown also has a second thickness d2d which is smaller than the first thickness d1e.
  • the diffusion barrier layer can also be formed in one side wall 11, 12 and applied to the other side wall 11, 12. Furthermore, the diffusion barrier layer may also be formed on or in the outer wall 14 and on or in the side walls 11, 12. The diffusion barrier layer can be formed completely or only partially in or on the side walls 11, 12.
  • the profile body 10 may further be trapezoidal, square, diamond-shaped or otherwise formed.
  • the bulges can assume other shapes, for example, be doubly booked, be asymmetrically bulged etc.
  • the reinforcement layer 40 may extend over the entire width b1 or only partially over the width b1.
  • the reinforcing layer 40 may also be applied asymmetrically.
  • an insulating disk unit with the spacer profile frame 50 is manufactured in the following steps.
  • the spacer profile in an embodiment described above is produced by, for example, extrusion.
  • a spacer profile frame 50 made by corresponding bending deformation of the spacer profile.
  • the ends of the spacer profile are joined together by means of a connector.
  • the side walls 11, 12 of the spacer profile 50 by means of diffusion-tight adhesive material in each case with a disc inside the Slices 51, 52 glued.
  • the remaining clear space between the inner sides of the disks on the side of the spacer frame 50 facing away from the panes 53 of the panes 51, 52 and of the adhesive material 61 is filled with a mechanically stabilizing sealing material 62.
  • the spacer frame can also be assembled from a plurality, preferably four individual spacer profiles by means of corner connectors to form a spacer frame.
  • the solution by means of a bending process is preferable.
  • the first and second thickness need not be constant, but may also be thicker at the edges, for example, than in a central area.
  • the chamber can also be divided by intermediate walls into several chambers.
