Definitions

  • the invention relates to a vacuum insulation panel according to the preamble features of claim 1 and a method for its production.
  • Vacuum insulation panels of this type are described, for example, in DE 102 26 188 A1 and are offered with various heat-insulating bodies and a wide variety of barrier film envelopes, in particular made of thermally sealable plastic film.
  • these embodiments have the disadvantage that if the VIP envelope is damaged, the vacuum is lost, as a result of which the excellent thermal insulation properties of the VIP are negatively changed. Damage is most likely to occur in the marginal and corner areas of the VIPs. These are often caused by improper handling, e.g. by the VIP is parked hard across the corner.
  • the object of the invention is to improve the dimensional stability and stability of a vacuum insulation panel, such a vacuum insulation panel should be easy and inexpensive to manufacture.
  • a frame in the form of a U-profile which also guarantees the desired dimensional accuracy, is clipped or clipped onto the panel on at least one side edge.
  • This clamping or clipping is easy to carry out and thus leads to low manufacturing costs.
  • the connection between the frame and the vacuum insulation panel remains detachable, which is particularly the case with inaccuracies or other problems Positioning is very advantageous because then a new, improved or corrected positioning can be carried out with (readjusting) the frame.
  • An expedient embodiment of the invention is e.g. a U-profile made of hard plastic, which is pushed onto the panel after the evacuation of the vacuum insulation panel at the side edges delimiting the insulation core. If required, the U-profile can also be secured against slipping by means of an adhesive, thermal bonding and / or mechanical or thermal jamming on the vacuum insulation panel.
  • the frame in one piece and to bend it around the vacuum insulation panel.
  • corresponding recesses are formed in the corner areas before bending, for example by punching, preferably in a triangular shape, in order to be able to bend the U-profile better and without bulges of material.
  • the profile frame can alternatively be made in several parts and so that the individual frame parts touch butt; in the corner areas, the profile frame can also be mitred. From this it can be seen that both individual profiles and an extruded profile for forming the frame are possible.
  • an expedient solution is to first design the edge profile in an L-shape and then the projecting leg to the respective panel thickness by means of thermal shaping or other shaping methods adapt.
  • vacuum insulation panels are made with coverings that have a central seam, it may be sufficient to ensure the protection of the end faces with flat profiles. These can e.g. by means of an adhesive connection to the side edges, namely the two VI P end faces.
  • the frame profiles are preferably made of foamed or injection molded plastics in order to minimize the heat flow through the frame profile caused by the frame profile with sufficient protection of the edges and corners. For this reason, it is also advantageous if the material thickness of the frame profile with its legs is chosen to be as thin as possible. It may also be advantageous to punch the frame profile along the Break through the side edges of the surface touching the vacuum insulation panel.
  • the frame with its legs can extend completely or at least largely over the entire vacuum insulation panel, especially in the case of smaller base areas.
  • the legs of the frame profiles can be extended in such a way that the entire vacuum insulation panel is enveloped by the frame profiles, or the frame profiles fix a protective plate on the top and / or bottom (flat sides) of the vacuum insulation panel.
  • the protective plates on the top and / or bottom of the vacuum insulation panel can consist of cardboard-like or metallic materials, of plastics, of foamed materials, of fabrics, etc. According to the invention, these protective plates can of course also be attached to the legs of the frame, the void which may arise between the protective plate and the vacuum insulation panel then being filled with a filler (e.g. foam vies). Furthermore, as an alternative, a smooth protective plate or a stepped protective plate can also be attached directly to the vacuum insulation panel in the case of plates set off at the edge. The height difference between the vacuum insulation panel surface and the upper edge of the frame profile can be compensated for so that there is no longer any heel. It is therefore also possible according to the invention to give at least one protective plate the height-compensating shape, so that the height difference between the vacuum insulation panel and the upper edge of the frame profile is filled.

  • Fig. 6 shows a preferred embodiment with respect to the frame of the invention
  • Vacuum insulation panels in top view are Vacuum insulation panels in top view.
  • a vacuum insulation panel 1 is shown schematically, which has a predetermined thickness (cf. double arrow) of, for example, 2 cm and from an insulation core 2 indicated here in gray, made of evacuable, open-pore materials (in particular microporous silica or the like). is formed with film covering or barrier film 3.
  • This barrier film 3 is, for example, in the Seal the area of the side edges with a sealed seam, as indicated by the horizontal arrow.
  • a frame 4 of U-shaped cross section with two legs 4a, 4b is placed on at least two side edges (only one shown here), which also shows the ensures the desired dimensions.
  • a preferred embodiment of the frame 4 is, for example, a U-profile made of hard plastic, in particular PVC, which, after the insulation panel 1 has been evacuated, is pushed or clamped or clipped onto the panel 1 at the side edges delimiting the insulation core 2.
  • the U-profile of the frame 4 can also be secured against slipping by means of an adhesive, thermal bonding and / or mechanical or thermal jamming on the vacuum insulation panel 1. In order to compensate for the height difference in the edge area, this can be designed with a thickness that is reduced compared to the thickness indicated by the double arrow, so that the legs 4a and / or 4b of the frame are more flush with the flat side.
  • the strip profiles of the frame 4 can preferably be mitred.
  • the frame 4 can also be designed such that the individual frame parts butt against one another in the corners.
  • the use of an extruded profile to form the frame 4 is also possible.
  • Fig. 2 an embodiment of the frame 4 is shown in order to reduce the effort required to provide different frame thicknesses at different thicknesses of the vacuum insulation panels 1.
  • An expedient solution is to first design the frame 4 in an L-shape (seen in cross section) and then to bend the projecting leg 4a by means of thermal shaping (see arc arrow) or to adapt it to the respective panel thickness (see double arrow) using other shaping methods ,
  • the vacuum insulation panels 1 are produced with wrapping foils 3, which have a central seam, it may be sufficient to provide the frame 4 only on the two end faces with the transverse seams. After clamping, these can optionally be additionally fixed to the side edges, namely the two VIP end faces, using an adhesive connection.
  • the frame profiles preferably consist of foamed or injection-molded plastics in order to minimize the heat flow caused by the frame 4 with sufficient protection of the edges and corners. For this reason, it is also advantageous if the material thickness of the frame 4 with its legs 4a and 4b is chosen to be as thin as possible. For further protection of the vacuum insulation panel 1 beyond its edges and corners, the frame 4 with its legs 4a and 4b can extend completely or at least largely over the entire vacuum insulation panel 1, in particular with smaller base areas.
  • Either the legs 4a, 4b of the frame 4 can be extended so that the entire vacuum insulation panel 1 is enveloped by the frame 4, or else the frame profiles fix a protective plate 5 on the top and / or bottom (flat sides) of the Vacuum insulation panels 1, as shown in Fig. 3.
  • the protective plates 5 can also be attached to the legs 4a, 4b of the frame 4, as shown in FIG. 4, the cavity which may arise between the protective plate 5 and the vacuum insulation panel 1 being filled with a filler 6 (for example foam vies). can be replenished.
  • a stepped protective plate 5 ' can also be attached directly to the vacuum insulation panel 1, as shown in FIG. 5.
  • the difference in height between the surface of the vacuum insulation panel 1 and the upper edge of the frame 4, here the upper leg, can be compensated in order to give the protective plate 5 'a height-compensating shape, so that the difference in height between the vacuum insulation Panel 1 and the upper edge of the frame 4 is filled.
  • FIG. 5 also shows a lateral expansion of the frame 4, for example to form an eyelet as a holder 7.
  • This can also be designed to be complementary, for example as a dovetail-shaped groove or multiple groove, into which a seal can be inserted between two frames 4 of adjacent panels 1.
  • This bracket 7 is preferably in one piece with the profile of the frame 4, e.g. designed as an extruded profile, so that there are no significant additional costs for this additional function.
  • Fig. 6 shows a top view of a preferred embodiment of the vacuum insulation panel according to the invention, in which the frame 4 with the legs 4a, 4b (only one leg is visible 4a) is formed from a single piece of frame profile.
  • the frame 4 has in each of its four corner areas a recess 8 in the legs 4a, 4b, which facilitates the bending of the frame profile by 90 °.
  • Recesses of different sizes are shown at the top left and bottom right, each of which has a gap, while the recesses at the bottom left and top right are dimensioned so that no gap is visible.
  • a preferred method for producing the vacuum insulation panel 1 according to the invention consists in first cutting an extruded profile to a length which is less than or equal to the circumference of the insulation core 2 covered with the barrier film 3, that is to say of the "bare" vacuum insulation panel 1 without a frame 4. Thereafter, recesses 8 are formed in those areas of the cut frame 4 which are provided as corner areas of the finished vacuum insulation panel 1.
