Description

The invention relates to a spacer and spacer assembly, a use for producing VIP and a use for producing rimless composite systems with the features mentioned in the preamble of respective independent claims.

It is known that force-bearing support elements are used in vacuum insulation for spacing the walls.

The US 2007 0286 981 A1 discloses a VIP panel with tension-loaded spacers uniformly distributed between a plurality of plates subjected to the external pressure differential force. One embodiment proposes to fasten a multiplicity of short fiber elements in each case at both ends, which could fail due to excessive manufacturing complexity and costs. Another embodiment uses two endlessly stretched fibers that intersect and attach to edges of the panel assembly. The fiber intersection causes very small bending radii, which limit each fiber significantly in their Zuglastragfähigkeit, so that the intended high power transmission can only be achieved with much thicker fiber filaments, which are then transmitted significantly more heat. Thus, there are no practicable solutions.

Previous patent applications to the present Applicant have presented tensile load-bearing and economically manufacturable spacers having very high power reserves in conductive heat transfer which outstrip all spacers / s claimed in compressive load. As long as only one or a few multilayers of these arrangements are sufficient, such as, for example, sufficient for building insulation, they provide excellent results. If the temperature differences become greater, as in high-temperature or cryogenic applications, then the heat radiation components quickly exceed the conductive advantages gained through their temperature dependence in the 4th power. It is complicated to provide heat radiation measures in the form of many small parts in these arrangements, which are constructed of continuous or discontinuous radiation suppression agents such as fine-porous fillers or multilayer insulation.

The invention has for its object to improve traction claimed spacers such that it is easy and economically possible to arrange radiation suppression means between the walls to be spaced and adapted to the particular application. Furthermore, it is a further object of the invention to reduce the conductive heat conduction via the spacers even more effectively.

The present invention is based on a spacer and spacer arrangement with at least one tension-transmitting element subjected to tensile load for heat transfer of spaced apart first and second load-distributing walls, pressure distribution plates and / or surfaces of objects. The acting force is above all the area-distributed pressure differential force, but also additionally applied mass forces to be understood by acting weights and accelerations. The spacer assembly further includes a plurality of opposing each on opposite wall, over the spacer center away from reaching behind projecting, with at least one clamped tensile force transmitting element connected pressure transducer, wherein between the different side pressure transducers, a gap of predetermined spacing is provided.

The objects of the invention are achieved in that in the spaced gap, a multilayer arrangement, comprising at least one heat radiation reflective designed, preferably metallized or metallic layer layer, unloaded by the spacing forces is arranged to exchange the heat radiation between spaced walls and / or surfaces of Suppress pressure sensor. An unloaded multilayer arrangement achieves thermal conductivity values up to 1E-5 W / mK. Both outer surfaces of the multilayer arrangement are preferably provided with a spacing layer, so that the surfaces of the pressure-sensing plates and the outer reflective layers of the multilayer arrangement are already each a mutually reflective screen pair used and the efficiency is thereby increased. The multilayer assembly contacts both surfaces of the pressure transducer plates in the spaced gap, but has a slightly lower overall thickness than the gap spacing, so that their individual layers are loosely disposed. It may also be advantageous to specify the thickness of the multilayer arrangement significantly smaller than the gap spacing, in order to provide better evacuation conditions along the gap.

According to a preferred embodiment of the present invention, the multilayer assembly is integrally formed over a plurality of pressure transducers to thereby facilitate assembly of the spacer assembly.

The multilayer arrangement is in a preferred embodiment along the tensile force transmission elements with Durchlasausschnitten or sections provided, in which the force transmitting to the pressure transducers portions of the tensile force transmission elements are inserted, so that the multilayer device itself remains unloaded. As a result, almost 100% of the spaced surfaces can be shielded by multilayer arrangement. Spacer arrangements with fiber extension means can also be provided in the spaced-apart gap with a multilayer arrangement.

In preferred embodiments, the width of the transmission cut-outs in the multilayer assembly is suitably and preferably minimized to the diameter of the fiber filaments of the tensile force transmitting elements used to preclude or minimize direct radiation exchange past the multilayer device, the distances between the transmission cut-outs and the individual fiber filaments being tensile Transmit elements match or match multiple of them. The fiber filaments are preferably concentrated to the allowable point loadability of the pressure transducers, so that the distance (a) between them and the transmission cut-outs may be larger, and consequently their number may be smaller.

The multilayer arrangement is further provided according to yet a preferred embodiment of the present invention with means for area-wide evacuation between the layers, said means may have cuts or perforation for evacuation and / or arranged between the layers getter and / or desiccant. The aperture cutouts or cuts already contribute to this functionality.

The multilayer arrangement is layered with spacing layers which are fabric-like, such that the fabric naturally frayes in the cut or punched edge regions. This fraying of the fabric causes an enlargement of the diameter of individual fiber filaments exactly at the edge, so that the reflective layers are even more clearly spaced at the edge. The layers are unloaded and wafer-thin, so that the low fracing forces that occur for this important spacing can be sufficient. The layer arrangement is aligned and fixed against displacements in a predetermined position, so that at the edge no contacts between reflective layers due to the edge deformation occur. For fixing the multilayer to edges, at least one spacer layer can be made with oversize and thereby exposed at the edge of the multilayer arrangement. These exposed portions may be attached to a pressure transducer plate by a mechanical fastener or adhesive.

The pressure transducers preferably have back cavities formed therein which may serve as evacuation passages of enlarged cross-section, with evacuation ports optionally distributed along the pressure transducers connecting these evacuation passages to the spaced apart gap to increase evacuation speed and / or quality.

The pressure distribution plates and / or walls can be formed from a sheet metal, plastic, press paper product, glass or ceramic. Furthermore, they can already be used to form the gastight barrier, which is thereby substituted.

The load bearing capacity of the pressure distribution plates and / or walls shall be such that they can carry the proportional surface forces between two adjacent equilateral pressure transducers. In order to increase the rigidity structures may be incorporated in the pressure transducer plates and / or in the walls to be spaced, z. As waves, grooves, corrugations etc ..

The spaced walls, pressure distribution plates or articles may according to a preferred embodiment of the present invention 2- or 3-dimensimal curved molding surfaces of any shape, the pressure transducer having a matched normal orientation and / or shaping. In the case of 2-dimensionally curved surfaces, the multilayer arrangement can usually be easily adapted to the curvature of the surface. In the case of 3-dimensionally curved surfaces, the multilayer arrangement can either be formed in a form-fitting manner or be configured in the form of completely or partially cut-off strips which are inserted between the well-deformable spacing layers of fibers.

The walls and / or Druckaufnehmerplatten are preferably formed of sheet metal or plastic, glass or ceramic, and optionally preferably on one or two sides provided with a radiation reflection layer or surface, which in particular face the spaced gap.

The width and length of the pressure transducer plates with pressure transducers are preferably predetermined for an intended temperature application, that different thermal expansion of the cold side and hot side pressure transducer plates and / or pressure distribution plates and / or walls is covered by the gap spacing and it can not lead to contact, wherein the tensile force Transmission elements are slidably disposed about the pressure transducer at least one of the spaced Druckaufnehmerplatten. So on Plates of predetermined size limited spacer assemblies can be strung together cover a large area, leaving between each a small edge gap is released. The different-side thermal expansions are thereby limited locally to one plate and do not add together.

The pressure transducers are preferably formed in one piece in the form of an asymmetrical corrugated plate, trapezoidal plate or corrugated plate of predetermined dimensions, wherein deep-drawing, pressing, injection molding and / or extrusion processes are to be preferred. For corrugated or trapezoidal plate back a clamping sheet may be provided, which may be either integral with the profile or subsequently attached and provides additional structural rigidity. The cavities in the corrugations or trapezoidal profiles form the evacuation channels for a rapid, area-wide evacuation of the arrangement and above all the closely spaced multilayer arrangement.

As a fiber for the tensile force transmission elements ( 1.30 . 2.30 ) heat-optimized fibers are used with favorable for the application temperature ratio of low thermal conductivity and high tensile stress.

The fibers may be selected from the following incomplete list: carbon, aramid, glass, S-glass, quartz glass, basalt, ceramic, stainless steel, tungsten, tantalum, Vectran® ^™ , Zylon® ^™ , Dyneema® ^TM , spider silk, plastics and other high-fiber and low-heat conductive fibers.

The spacer arrangements according to the invention are preferably to be evacuated to a pressure at which the mean free path of the residual gas molecules is greater than the spacing between the layers of the multilayer arrangement and / or the sections uncovered by it.

The multilayer arrangement preferably has as layers metal foils and / or metallized plastic carrier films and / or metal-oxide-coated and / or ceramic-coated films and / or metamaterial layer (s). The emissivity rate of the reflective layers is preferably between 1 and 10%, more preferably between 0.5 and 5%, even more preferably between 0 and 2%. At very high temperatures, heat-resistant materials must be used, which may have much higher emissivity.

The layer density of the multilayer arrangement is preferably between 5 and 50, more preferably between 10 and 30, even more preferably between 15 and 20 per mm of thickness.

The thermal conductivity of the multilayer arrangement related to radiation and conduction is, for example, in the range of 0.00001 W / mK (at 300 K).

The ceramic oxide or metal layer thicknesses of the multilayer device layers are preferably between 10 and 100 nm, more preferably between 20 and 70 nm, even more preferably between 30 and 50 nm thick.

The reflective layers of the layers of the multilayer arrangement can be selected from an incomplete list of copper, aluminum, gold, silver, platinum, tin, chromium, TiN or a metal oxide or ceramic layer and combined as desired.

The individual layers are isolated from each other by means of shaping by wrinkling or knobbly shaping or by interposed planar spacer layers against conductive heat transfer from one another and / or the walls and / or pressure sensors. The sheet-like spacer layers can be formed from glass fibers or other fibers as a woven fabric, net, paper or nonwoven fabric or from cellulose or synthetic fibers.

According to another aspect of the invention, their objects are achieved by use of the spacer assembly of any of the previously described embodiments or combinations thereof for manufacturing evacuated or vacuum insulated vacuum panels, wherein at least one spacer assembly of at least one sealed gas-tight envelope. The gas-tight envelope is preferably formed thermally insulating at least in the edge region of a thin metallic foil or thin metal-coated plastic film.

In the process, empty spaces are created between the spacer arrangements, forming a branched channel system and serving for the evacuation of at least one common evacuation and Befluidungsanschluss from the accessible sections of the respective gas-permeable sheaths of the spacer assemblies.

Further preferred embodiments of the invention will become apparent from the remaining, mentioned in the dependent claims characteristics.

The invention will be explained below in embodiments with reference to the accompanying drawings. Show it:

1 a schematic perspective view of a first preferred embodiment of the spacer assembly according to the invention in exploded view; and

2 a partial cross-sectional view of the spacer assembly according to the invention.

1 shows a schematic perspective view of a first preferred embodiment of the spacer assembly according to the invention 1 in exploded view on the basis of a small section.

As a non-symmetrical corrugated plate formed Druckaufnehmerplatte 201 has wider troughs than peaks, so that a similarly trained second pressure transducer plate 200 is positionable in an inverted position spaced apart.

On the lower pressure transducer plate in the picture 201 is a multilayer arrangement 203 / 1p placed, which has at least one preferably coated on both sides reflective coated layer and on both sides a spacing layer. Typically, in a gap spaced about 1mm, 10-20 layers may be disposed without passing through the pressure sensing plates 201 and 200 pressed together. The multilayer arrangement 203 / 1p may touch both pressure transducer plates as it itself has a very low heat conduction of about 1E-5 W / mK. It can be realized to accommodate a larger number of layers correspondingly larger spacings, so that an adaptation to any application can be realized with simple technical means.

The multilayer arrangement 203 / 1p is the shape of the pressure transducer plate 201 but it does not necessarily have to be attached to it. At predetermined intervals a, the multilayer arrangement has 203 / 1p cut into her or just cut-through cut-outs 203 / 1pn on, for receiving the at the pressure transducers 201 / i . 200 / i force transmitting abutting portions of the tensile force transmission elements 30 / n serve. The width of these Durchlasausschnitte can be specified so that it is ensured that on the one hand as little as possible unprotected surface of the pressure transducer is formed and on the other hand, the metallic layers of the individual layers do not come into contact.

The spaced apart by the predetermined amount a extending portions of the tensile force transmission elements 30 / n are at the edges of the pressure transducer plate 201 attached. For this purpose, they are preferably combined to form a fiber mat and clamped between two clamping bars with an exact enough predetermined length (not shown) or alternatively in an endless loop around the pressure transducer plate 201 created.

The in the Durchlasausschnitte 203 / 1pn the multilayer arrangement 203 / 1p inlaid sections of the tensile force transmission elements 30 / n at the same time hold the multilayer arrangement 203 / 1p against shifts along the wave mountains.

2 shows a partial cross-sectional view of the spacer assembly according to the invention 10 ,

The two pressure transducer plates 106 and 107 at the same time serve as clamping plates for the corrugated sheets 200 and 201 , The contact points or areas 200 / m can be frictionally connected by welding, soldering or gluing and thus structurally stiffen every wave crest. The voids 121/1 and 121/3 Among the pressure transducers designed as wave crests, they preferably serve as an evacuation channel system branched far over the surface. That's important because the multilayer layout 203 / 1p very closely spaced and formed over a large area. Also the gap space 121/2 is used for evacuation, but it is with the multilayer arrangement 203 / 1p almost completely filled and therefore offers a considerable Evakuierungswiderstand.

The mutually facing surfaces of the mutual pressure transducer 200 / i and 201 / i are preferably each provided with a reflective layer. However, they can also be formed without such reflection layers, since the multilayer arrangement 203 / 1p very effective at suppressing heat radiation.

The attachment of the sections of the traction transfer elements 30 / n can as shown for example by means of a clamping bar 30.5 take place, preferably on the back of the pressure transducer plate 201 deflected and fixed there. This attachment is preferably by snapping or clamping or by melt bonding or gluing with an adhesive suitable for temperature and vacuum application. To stabilize this last force-absorbing section, an edge support can be used 107/91 to be helpful.

The number and layer density of the layers in the multilayer arrangement 203 / 1p can be customized for an application. Because the conductive heat transfer through the traction transfer elements 30 / n Thermal conductivity in the range of 1E-5 W / mK (at 300 K) can reach and the multilayer arrangement reaches a same magnitude, it is possible with the spacer assembly according to the invention to achieve this magnitude of thermal insulation performance. This makes it possible to carry out the outer gas-tight enclosures of insulated objects such as containers and pipes very thin-walled and to reduce the thickness of insulation considerably.

So that at the traction transfer elements 30 / n against each other spanned pressure transducer plates 200 and 201 do not tilt and come into contact locally, holding means are used according to the invention. The holding means may be formed as projections which are subject to pressure and which are already produced during the shaping of the pressure-sensing plates (not shown) or as holding fibers which are subjected to tensile load 300/6 be formed. The retention fibers 300/6 are distributed in the area and prevent the gap distance between the pressure transducer plates 200 and 201 can be increased as a result of tilting. As a result, no corresponding shortening of the gap spacing Δh and / or Δd can take place at another location. The holding fibers may, for example, as a closed loop by two through holes through both Druckaufnehmerplatten 200 and 201 be executed and distributed over the surface of the arrangement to be arranged.

The length and width dimensions of a pressure transducer plate 200 and 201 are specified so that the different thermal expansion of the cold and warm walls or pressure distribution plates can still be balanced sufficiently secure.

It should be noted that the illustrated embodiments can not describe the entire scope of the present invention, but it is possible for one of ordinary skill in the art to create further embodiments of the invention, which are covered by the scope defined in the claims, without being inventive step got to.
