Abstract

The insulating elements in the form of boxes are esp. used in the building industry. The boxes are made from foil or sheet metal. The material used for the boxes has high resistance against heat conductance. The boxes are flat and have stepped edges so that the sides of the boxes can overlap, when placed on a surface to be insulated. The boxes are evacuated after the two shells which form a box are joined together. To prevent the boxes from collapsing under external pressure, they are filled with distance pieces made from insulating material.

Description

Element zur Wärmeisolation Die Erfindung betrifft ein Element zur Wärmeisolation für ebene und/oder gekrümmte Oberflächen, das evakuierbar ist und trotzdem unter atmosphärischen Bedingungen eingesetzt werden kann.Element for thermal insulation The invention relates to an element for Thermal insulation for flat and / or curved surfaces that can be evacuated and can nevertheless be used under atmospheric conditions.

Isolationssysteme unter Zuhilfenahme eines Vakuums sind aus der Kryogentechnik bereits seit langem bekannt, beispielsweise in der Form der sogenannten DEWAR-Gefäßes Diese Systeme beruhen auf der Überlegung, den l;ärnzetransport durch Konvektion zu vermeiden. Da gleichzeitig der härmetransport durch Wärmeleitung praktisch ausgeschlossen ist, kann lediglich noch Wärme durch Strahlung übertragen werden. Um dem zu begegnen, werden im allgemeinen die Oberflächen dieser Systcne, soweit zwischen ihnen ein l.ärmeaustausch durch Strahlung erfolgen könnte, verspiegelt oder die Strahlung durch das Einbringen von wenig emittierenden Folien oder porösen Stoffen verkleinert.Isolation systems with the aid of a vacuum are from cryogenic technology already known for a long time, for example in the form of the so-called DEWAR vessel These systems are based on the idea that the transport of medicine by convection to avoid. Since at the same time the transport of heat by conduction is practically impossible is, only heat can still be transferred by radiation. To face that are generally the surfaces of these systems as far as there is one between them l. heat exchange could take place through radiation, reflective or radiation reduced by the introduction of low-emitting foils or porous materials.

Die bisher bekannten Vakuum-Systene, die unter atmosphärischen Bedingungen verwendbar sind, bestehen aus zwei ineinander angeordneten Behältern, die aufgrund ihrer Formgebung die atmosphärischen Kräfte aufnehmen. Dalurch sind diese Systeme auf relativ kleine mit im allgemeinden gekrü:inten Flächenabmessungen beschränkt und nicht für Wärmeisolationszwecke, z.B. im Bauwesen, verwendbar.The previously known vacuum systems that operate under atmospheric conditions are usable, consist of two nested containers due to their shape absorb the atmospheric forces. These are the systems limited to relatively small with generally curved surface dimensions and cannot be used for thermal insulation purposes, e.g. in construction.

Die Aufgabe der Erfindung ist es, Bauelemente speziell für diese letztgenannten Zwecke anzugeben, die unter Ausnutzung der Vorteile der Vakuun-Sstee verwendbar sind. Erfindungsgemäß besteht das Element aus einem aus Folien oder Blechen aus schlecht wärmeleitendem Material geformten evakuierbaren plattenförmigen Behälter und in diesem Behälter angeordneten Isolationswerkstoffen als Abstandshalter zur Aufnahme der atmosphärischen Kräfte. Der Behälter kann aus diffusionsdichten dünnen Folien aus einem schlecht wärmeleitenden Metall geformt sein. In diesem Fall ist es zweckmäßig, als Isolationswerkstoff Glasseidenfilz zu verwenden. Der Behälter kann aber auch aus Deckbleelien und die Deckbleche im Randbereich verbindenden dünnen Folien geformt sein. Vorteilhaft ist dabei die Verwendung biegesteif gesickter Bleche aus einem schlecht wärmeleitenden Metall, die gegebenenfalls quer zur Sickenrichtung durch aufgesetzte Profile versteift sind.The object of the invention is to develop components specifically for the latter Indicate purposes which can be used while taking advantage of the vacuum sstee are. According to the invention, the element consists of a foil or sheet metal Badly thermally conductive material shaped evacuable plate-shaped container and insulation materials arranged in this container as spacers for Absorption of the atmospheric forces. The container can be made of diffusion-proof thin Foils be formed from a poorly thermally conductive metal. In this case it is it is advisable to use fiberglass felt as the insulation material. The container but can also thin from cover sheets and the cover sheets connecting in the edge area Foils be shaped. The use of rigidly corrugated sheets is advantageous Made of a poorly thermally conductive metal, which may be transverse to the direction of the bead are stiffened by attached profiles.

Als Abstandshaltesystem sind bei dieser Ausführung Röhren oder in Röhren geführte Kugeln oder linsenförmige Körper oder Körper einer Form, die cinen geringen Wärmedurchgang gewährleisten, zweckmäßig.In this version, tubes or in Tubular guided spheres or lenticular bodies or bodies of a shape that cinen ensure low heat transfer, expedient.

Zur Verringerung der Berührungsflächen können die Röhren an ihren Enden angeschärft sein. Zur Verminderung der Wärmeübertragung durch Strahlung ist es vorteilhaft, in den Behälter parallel zu den Deckblechen einige wenig emittierende Folien einzulegen, die gegeneinander - zum Beispiel durch Glasseidengewebe - schlecht wärmeleitend abgestützt sind.To reduce the contact areas, the tubes can be attached to their Ends be sharpened. To reduce the heat transfer through radiation it is it is advantageous to have a few less emissive elements in the container parallel to the cover plates Inserting foils that are against each other - for example through glass silk fabric - bad are supported in a thermally conductive manner.

Im Bereich des Randes tritt durch die metallische Verbindung der Deckfolien ein erhöhter Wärmefluß auf. Dabei ist vorzugsweise die Dicke der Elemente im Randbereich in einer Stufe auf die halbe Stärke reduziert.In the area of the edge occurs through the metallic connection of the cover foils an increased heat flow. The thickness of the elements is preferably in the edge area reduced to half strength in one step.

Auf diese Weise wird der leärmeleitungsweg im Randbereich verlängert und der 'iärmedurchgang bei t.berlappung mehrerer Elemente verkleinert.In this way, the noise conduction path is lengthened in the edge area and the heat passage is reduced when several elements overlap.

Die Elemente können mit den aus der Vakuumtechnik bekannten Verfahren zusätzlich behandelt werden, indem beispielsweise die dem Vakuum ausgesetzten Teile vor der Montage gasfrei geglüht sind.The elements can be processed using the methods known from vacuum technology are additionally treated, for example by the parts exposed to the vacuum have been annealed gas-free prior to assembly.

Ferner können in den Elementen Adsorbersubstanzen und/oder von außen aktivierbare Ionengettermaterialien vorgesehen sein.Furthermore, adsorber substances and / or from the outside can be in the elements activatable ion getter materials may be provided.

Die erfindungsgemäßen Isolationselemente sind mit einfachen Verfahren herstellbar und lassen die großen Vorteile der Va#uum-Isolation auch für größere Flächen, wie sie beispielsweise im Bauwesen, in der Gas-TankSchiffahrt usw. üblich sind, zur An-wendung bringen.The insulation elements according to the invention are made using simple methods manufacturable and allow the great advantages of the Va # uum isolation also for larger ones Areas such as are common in construction, gas tank shipping, etc. are to apply.

In dem Beispiel nach Figur 2 ist das Element aus gesickten Deckblechen 6 geformt, die gegeneinander durch Abstandshaltesysteme 7 zur Aufnahme der atmosphärischen Druckkräfte abgestützt sind. Im Randbereich sind die Deckbleche 6 durch dünne Randfolien 5 miteinander verbunden, wobei diese Randfolien 5 an ihren Berührungsflächen 3 miteinander diffusionsdicht, wie bein Beispiel nach Figur 1, verbunden sind. Zur Aufnahme von Längskräften sind die Deckbleche 6 durch aufgesetzte Profile 8 quer zur Sickenrichtung der Deckbleche versteift. In den Innenraum des Elementes sind dünne Folien 9 mit einer sehr geringen Emissionszahl eingelegt, die durch Glasseidengewebe voneinander getrennt sind. Auch in diese Elemente sind Adsorptionsstoffe 4 eingebracht.In the. Adsorbents 4 are inserted in the vacuum space 11. In the example According to Figure 2, the element is formed from corrugated cover plates 6, which against each other supported by spacer systems 7 to absorb the atmospheric pressure forces are. In the edge area, the cover plates 6 are interconnected by thin edge foils 5 connected, these edge foils 5 being diffusion-tight with one another at their contact surfaces 3, as in the example of Figure 1, are connected.
