Abstract
The invention relates to a gastight enclosure for vacuum-insulating arrangements, comprising a carrier film of plastic with at least one thin gastight coating of metal, for the complete or at least partial enclosure of an evacuated hollow space, in particular for the gastight sealing of peripheral heat bridges. It is provided that the metallic coating is formed with a metal of particularly low thermal conductivity. The metallic coating preferably comprises a metal with low thermal conductivity from the following nonexhaustive list: titanium, high-grade steel, lead, tin, zinc, bismuth, tantalum, nickel, platinum, tungsten or alloys thereof. Furthermore, use of the gastight enclosure for the gastight peripheral sealing of VIP (vacuum-insulated panel), VIG (vacuum-insulated glass) and/or an edgeless vacuum-insulated composite system at unavoidable peripheral sealing portions is envisaged.
Description
Gasdichte Hülle für Vakuum isolierende Anordnungen Gas-tight envelope for vacuum insulating arrangements
Die Erfindung betrifft eine gasdichte Hülle für Vakuum isolierende Anordnungen und eine Verwendung dieser mit den im Oberbegriff des jeweiligen unabhängigen Anspruchs genannten Merkmalen. The invention relates to a gas-tight envelope for vacuum insulating arrangements and a use of these with the features mentioned in the preamble of the respective independent claim.
Es ist bekannt, dass Vakuum isolierende Anordnungen wie VIPs (vacuum insulated panel), VIGs (vacuum insulated glas) und Randlos-Verbund-Systeme insbesondere in deren unvermeidbaren gasdicht zu verschleißenden Randbereichen Wärmebrücken aufweisen müssen. Speziell bei kleineren Objekten wie VIPs, VIGs oder bspw. Kühlboxen erreicht der zusätzliche Wärmeübertrag oft den Wert der ganzen übrigen Anordnung oder übertrifft ihn gar. Es werden wegen geforderte Vakuumdichtheit ausschließlich gasdichte Stoffe wie Metalle oder Glas/Keramik dazu eingesetzt, weil Kunststoffe zu hohe Gasdurchlässigkeit haben. Man verwendet zumeist eine 10 bis 50E-6 m dünne Edelstahlfolie mit ihrem niedrigen für Metalle Wärmeleitwert von nur 15 W/mK oder eine Kunststofffolie mit 50-100E-9 m aufgesputterter oder aufgedampfter Aluminiumschicht. Aluminium hat sich wegen seiner großen Verbreitung zur Herstellung von metallisierten Folien für Lebensmittelverpackungen und für Reflexionsfolienanwendungen durchgesetzt, weist jedoch eine sehr hohe It is known that vacuum-insulating arrangements such as vacuum-insulated panels (VIGs), VIGs (vacuum insulated glass) and rimless composite systems, in particular in their unavoidable marginal areas to be worn in a gas-tight manner, must have thermal bridges. Especially with smaller objects such as VIPs, VIGs or, for example, cool boxes, the additional heat transfer often reaches the value of the rest of the arrangement or even surpasses it. Due to the required vacuum tightness, only gas-tight materials such as metals or glass / ceramics are used because plastics have too high gas permeability. A 10 to 50E-6 m thin stainless steel foil is usually used, with a low thermal conductivity of only 15 W / mK for metals, or a 50-100E-9 m plastic foil sputtered or vapor-deposited on aluminum. Aluminum has become widely used in the production of metallized films for food packaging and reflective film applications, but has a very high
Wärmeleitfähigkeit von 260 W/mK auf. Deswegen ist man bemüht, die Schichtdicke möglichst dünn zu halten, bspw. 20 nm oder 3 mal 20 nm. Bei solch dünnen Metallschichten sind jedoch sogenannte„pin-holes" vorhanden, sodass die Gasdichtheit nur für groben Vakuum von 1 bis 100 mbar zufriedenstellend ist. Dadurch ist man gezwungen, als Thermal conductivity of 260 W / mK on. Therefore, it is endeavored to keep the layer thickness as thin as possible, for example. 20 nm or 3 times 20 nm. However, so-called "pin holes" are present in such thin metal layers, so that the gas tightness is satisfactory only for coarse vacuum of 1 to 100 mbar This forces you to be considered

Randwärmebrücken erheblich und führen zu einer Minderung des Wärmeleitwertes von VIPs bspw. von 0,004 W/mK„in der Mitte" um Faktor 2 bis 10. Ferner müssen die VIPs nach Ablauf ihrer Lebensdauer erneuert werden, da deren Wärmedämmung bereits nur noch halb so gut wie am Anfang ist. Edge thermal bridges significantly and lead to a reduction in the thermal conductivity of VIPs, for example. From 0.004 W / mK "in the middle" by a factor of 2 to 10. Furthermore, the VIPs must be renewed at the end of their service life, since their insulation is already half as good as in the beginning.
Der Erfindung liegt die Aufgabe zugrunde, eine gasdichte metallische Beschichtung derart zu verbessern, dass der Wärmeübertrag durch sie deutlich reduziert wird und/oder eine größere
Gasdichtheit erreicht wird, die eine längere Lebensdauer und/oder Nutzung preiswerter Füllstoffe bei tieferem Vakuum ermöglichen. The invention has for its object to improve a gas-tight metallic coating such that the heat transfer is significantly reduced by them and / or a larger Gas tightness is achieved, which allow a longer life and / or use of low-cost fillers at a lower vacuum.
Die erfindungsgemäßen Aufgaben werden dadurch gelöst, dass bei einer gasdichten Hülle für Vakuum isolierende Anordnungen, aufweisend eine Kunststoffträgerfolie mit wenigstens einer dünnen gasdichten Beschichtung aus Metall, die zur vollständigen oder wenigstens abschnittsweisen Umhüllung eines evakuierten Hohlraums, insbesondere zum gasdichten Versiegeln von Wärmerandbrücken verwendet wird, die metallische Beschichtung mit einem Metall besonders niedriger Wärmeleitfähigkeit ausgeführt ist. The objects of the invention are achieved in that in a gas-tight envelope for vacuum insulating arrangements, comprising a plastic carrier film with at least one thin gas-tight coating of metal, which is used for the complete or at least partially wrapping an evacuated cavity, in particular for the gas-tight sealing of heat sand bridges, the metallic coating is performed with a metal of particularly low thermal conductivity.
Gemäß einer bevorzugten Ausgestaltung der vorliegenden Erfindung weist die metallische Beschichtung ein Metall mit niedriger Wärmeleitfähigkeit aus einer nicht vollständigen Aufzählung von Titan, Edelstahl, Blei, Zinn, Zink, Bismut, Tantal, Nickel, Platin, Wolfram oder deren Legierungen. Dabei haben diese Metalle folgende Wärmeleitwerte Bismut/Wismut ( 8,4 W/mK), Platin (71 W/mK), Silizium (148 W/mK), Quecksilber (8,3 W/mK), Zinn (67 W/mK) Zink (1 10 W/mK), Nickel (85 W/mK), Tantal (54 W/mK), Blei (35 W/mK), Wolfram (167 W/mK) und Edelstahl 15 W/mK. Es ist möglich, mit bekannten Aufsputterungs- und/oder Aufdampfungsverfahren sogar Edelstahlschichten auf Kunststofffolien abzuscheiden. Bismut ermöglicht somit für Anwendungen unter 200 Celsius eine Reduzierung der Randwärmeübertragung um Faktor 30 oder bei verdoppelter Dicke und somit wesentlich besserer Gasdichtheit noch um 15. Bismut ist zudem ungiftig und hat besonders dichten Schichtaufbau, sodass mit einer erhöhten Gasdichtheit zu rechnen ist. According to a preferred embodiment of the present invention, the metallic coating comprises a low thermal conductivity metal from an incomplete list of titanium, stainless steel, lead, tin, zinc, bismuth, tantalum, nickel, platinum, tungsten or their alloys. These metals have the following thermal conductivity bismuth / bismuth (8.4 W / mK), platinum (71 W / mK), silicon (148 W / mK), mercury (8.3 W / mK), tin (67 W / mK ) Zinc (1 10 W / mK), nickel (85 W / mK), tantalum (54 W / mK), lead (35 W / mK), tungsten (167 W / mK) and stainless steel 15 W / mK. It is possible to deposit even stainless steel layers on plastic films with known Aufsputterungs- and / or vapor deposition. Bismuth thus allows for applications below 200 Celsius, a reduction of the edge heat transfer by a factor of 30 or doubled thickness and thus much better gas tightness even by 15. Bismuth is also non-toxic and has a particularly dense layer structure, so with increased gas tightness is expected.
