Definitions
- the invention relates to a vacuum insulation body according to the preamble of claim 1 and a corresponding manufacturing method.
- Vacuum insulation bodies are increasingly used in insulation and insulation in a variety of applications.
- a vacuum insulation body is understood to be an insulation element which has a core or supporting body made of an open-cell, open-pore, microporous and / or fibrous material, which is enveloped by a film and then evacuated.
- the attenuation values of such materials can be significantly improved by keeping them in an evacuated environment.
- up to 10 times higher insulation values can be achieved so that the layer thickness of the insulation panels can be reduced by the corresponding value.
- barrier materials are used, in particular multilayer films in which alternate metal layers, metallized layers and plastic layers.
- vacuum insulation bodies is also critical that in the areas in which a vacuum insulation body abuts the next, so-called bridges arise, for example cold bridges, which significantly reduce the insulation values of the total insulation compared to the insulating values of a single vacuum insulation body.
- the cause of these bridges is usually that in the conventional vacuum insulation bodies, a jointless juxtaposition of adjacent vacuum insulation body is practically impossible.
- the core which is moved further by a transport device, takes the film web with a leading edge. Then pivots a welding jaw up, while the film roll is braked to keep the film web taut. As a result, however, considerable forces are exerted on the fragile core blank, so that it can break out just in the edge area. This not only affects the fit. Rather, broken core material can also have a negative effect on the seal, in particular if the additional nonwoven covering is to be dispensed with for cost reasons.
- Object of the present invention is therefore to provide a vacuum insulation body available, which can be connected almost seamlessly to a similar vacuum insulation body, and is inexpensive to produce by a corresponding manufacturing process.
- the vacuum insulation body according to the invention has a core made of a microporous material, which is surrounded on its flat top and bottom by a sheath with two sealing seams in the longitudinal direction.
- the core is thus completely surrounded by two blank sheets of a gas-tight multilayer film.
- a gas-tight multilayer film is understood as meaning a film in which at least two plastic layers alternate with at least one barrier layer.
- Such a multilayer film is: polyamide / nylon - metal layer - polypropylene - polyester - metal layer - polyethylene.
- the individual layers are interconnected, for example by lamination. The end edges of the film are thus gas-tightly sealed together after welding.
- a vacuum insulation body is achieved in which the sealing seams or the welds closely fit tightly against the core and practically do not apply.
- the evacuation of the envelope of the vacuum insulation body is usually carried out prior to sealing, whereby also methods are known in which a first "partial" sealing takes place, which is then completed after evacuation.
- the vacuum insulation body according to the invention essentially has the dimensions of the core plus the thickness of the multilayer film used.
- the seal seams are extremely flat and closely conform to the microporous core.
- the sealing seams to the center each offset by a few centimeters against each other on the top and bottom of the vacuum insulation body.
- the respective sealing seam offset from each other by about one third of the total width of the vacuum insulation body to the central axis. Since the staggered sealing seams are relatively flat by the above configuration, the transverse seals on the narrow side can be sealed particularly well. This also causes the transverse Sealing seams kept relatively flat, which further prevents bridging between adjacent vacuum insulation bodies. Furthermore, it is achieved by attaching the sealing seams adjacent to the core as close as possible to ensure that the excess film material can be placed in the corner region around the edges of the core, which in turn results in a compact construction.
- FIG. 1 shows a section through a vacuum insulation body according to the invention.
- FIG. 2 is a perspective view of FIG. 1;
- FIG. 4 is a perspective view of a completed vacuum insulation body.
- the vacuum insulation body 1 has a core 2 of a microporous material which is completely enveloped by a multilayer film 3.
- the vacuum insulation body 1 of the embodiment of FIGS. 1 and 2 is a plate-shaped vacuum insulation body 1 or flat cuboid.
- a first sealing seam 4 runs on the upper side 18 approximately in the middle region of the vacuum insulation body 1 and displaces a second sealing seam 4 'on the lower side for this purpose.
- These two sealing seams 4 and 4 'on the two main surfaces here, the upper and lower flat sides 18 and 18' in comparison to the narrower end faces 12, 13 and 14, 17, see Fig .. 4) can also in the opposite direction of the Center offset, as shown in Fig. 2.
- sealing seams 4 and 4 ' are formed by respectively sealing the end edges 5 and 6 of the multilayer film 3 in the area where they abut and overlap.
- FIG. 3 shows in addition to the preparation of the two sealing seams 4 and 4 'after inserting a core 2 in a longitudinal welding device and a transverse sealing seam 15.
- This sealing seam 15 is carried out closely to the core 2 in order to achieve the closest possible envelope.
- the film material remaining from the covering is folded in the corner regions 10 and 11 of the vacuum insulation body 1 into a triangle which fits snugly against the core 2 or the end faces of the vacuum insulation body 1.
- Kälte Thermal bridges are avoided.
- FIG. 4 shows a perspective view of the finished vacuum insulation body 1.
- the vacuum insulation body 1 offset from the central region of the upper side 18 has the sealing seam 4, which is about one third of the opposite sealing seam 4 'at the bottom 18' Overall width is offset.
- the vacuum insulation body 1 has transverse seams 15, which are formed on the respective end faces 12 and 13 of the vacuum insulation body 1. By the offset of the longitudinal seams 4 and 4 'thus a film accumulation on the respective transverse seam 15 is advantageously avoided.
- the excess foil or the corner regions 10 and 11 are respectively folded over to the front sides 12 and 13, but can also be folded down to the narrow sides 14 and 17.
- This proposed method allows by format change readily adaptation of the film wrapping to strongly varying dimensions of the shaped body (width, length and height) in the automated manufacturing process, which is shown schematically in Fig. 3.
- this can be for smaller format changes usually on a change of the film rolls (in Fig. 3 below the Welding device shown omitted), since the overlap region of the sealing seams 4 and 4 'are chosen wider, which can be carried out in a considerably shorter time, so means a time savings.
