Description
Gegenstand der Erfindung ist ein Isoliermittel gegen Wärmeaustausch, das aus Lufträume einschließenden Trennschichten zusammengesetzt ist, die aus blanken Metallfolien bestehen 5 oder mit blanken Metallfolien plattiert sind oder blanke rückstrahlende Oberflächen haben. Die bekannten Isoliermittel dieser Art haben den Mangel, daß die Anordnung der Schichten nicht formbeständig genug ist, um eine wirksame Ausnutzung der Luft als Isoliermittel zu erreichen oder das Entstehen von Wärmebrücken durch Berührung der metallischen Schichten zu vermeiden. Es sind zwar auch schon derartige Isolierungen bekanntgeworden, bei welchen aus den Isolierschichten selbst durch Abbiegungen oder, Falze Abstandhalter gebildet werden, doch sind dieselben entweder zuwenig standfest und verfehlen daher ihr Ziel, oder sie leiten die Wärme in erheblichem Maße und sind daher ausgesprochene Wärmebrücken.The invention relates to an insulating agent against heat exchange, which is composed of separating layers enclosing air spaces which consist of bare metal foils 5 or are clad with bare metal foils or have bare reflective surfaces. The known isolating agents of this type have the Lack that the arrangement of the layers is not dimensionally stable enough for effective use the air as an insulating medium or the formation of thermal bridges Avoid touching the metallic layers. There are already such things Insulations become known, in which from the insulating layers themselves by bending or, folds spacers are formed, but these are either too little stable and therefore miss their target, or they conduct heat to a considerable extent and are therefore pronounced thermal bridges.
Diese die praktische Verwendbarkeit der Metallfolieisolierungen erfahrungsgemäß weitgehend beschränkenden Nachteile werden bei der vorliegenden Anordnung dadurch vermieden, daß die Abstandhalter zwischen den Trennschichten als die Wärme schlecht leitende Bänder oder Streifen ausgebildet sind, welche netz- oder gitterförmig verlaufen. Die Abstandhalter sind als dünne Streifen aus die Wärme schlecht leitenden Stoffen, z. B. Asbeststoffen, oder aus Metallfolie hergestellt, welche infolge ihrer geringen Dicke die Wärme schlecht leiten. Das wesentlich Neue gegenüber den bisher bekannten Metallfolieisolierungen ist hier also, daß die Dicke der Luftschichten völlig gewährleistet wird, während anderseits die abstandhaltenden Stege keine Wärmebrücken bilden.Experience has shown that this largely increases the practical usability of the metal foil insulation limiting disadvantages are avoided in the present arrangement, that the spacers between the separating layers are poorly conductive to heat Bands or strips are formed which run in the form of a net or grid. The spacers are as thin strips of the heat poorly conductive materials, z. B. asbestos materials, or made of metal foil, which are poor conductors of heat due to their small thickness. The essentially new thing compared to the previously known metal foil insulation is here that the thickness of the air layers is fully guaranteed, while on the other hand the spacing Bars do not form thermal bridges.
Der gleichmäßige Abstand der Trennschichten ist sowohl für eine wirksame Ausnutzung der Isolierwirkung der Luft als auch für die Beschränkung des Wärmeüberganges durch Strahlung von entscheidender Bedeutung. Denn Abweichungen des Schichtabstandes von seinem Mittelwert bedeuten eine Vermehrung der Wärmeleitung an der Stelle des verminderten Abstandes und besonders zugleich eine Vermehrung der Wärmestrahlung, weil der für sie maßgebende Unterschied der 4. Potenz der Oberflächentemperaturen durch jede Ungleichmäßigkeit der Temperaturverteilung erhöht wird. Die zellenförmige Unterteilurig ergibt für die Dauerwirkung metallischer Isolierflächen noch' den besonderen Vorteil, daß der durch entsprechend inniges Zusammenfügen oder organisches Verbinden der Isolierschichten mit den Abstandhaltern erzielbare Abschluß der Luft die oxydierende Einwirkung derselben auf die blanken Metalloberflächen herabsetzt. Für die Dauerwirkung der Isolierung ist auch die Erhaltung des gleichmäßigen Schichtabstandes durch eine genügend druckfeste, formbeständige Anordnung, wie sie Gegenstand der Erfindung ist, sehr wichtig. Außerdem gewährt ein solcher Aufbau den wesentlichen Vorteil, daß die Schutzhüllen ohne besondere, die Isolierwirkung durchbrechende Abstandhalter gelagert und ohne solche Abstandhalter, ζ. B. in Gestalt von zusammengefalztenFolienumhüllungen, luftdichtThe even spacing of the separating layers is essential both for an effective use of the Isolating effect of the air as well as for the restriction of the heat transfer through radiation vital. Because deviations of the layer distance from his Mean values mean an increase in heat conduction at the point of decreased Distance and especially at the same time an increase in thermal radiation, because that for them decisive difference to the 4th power of the surface temperatures due to any unevenness the temperature distribution is increased. The cellular subdivision gives for the permanent effect of metallic insulating surfaces still 'the particular advantage that the through corresponding intimate joining or organic bonding of the insulating layers with the Spacers achievable completion of the air the oxidizing effect of the same on the bare metal surfaces. Preservation is also important for the long-term effect of the insulation the even layer spacing through a sufficiently pressure-resistant, dimensionally stable Arrangement, as it is the subject of the invention, very important. In addition, such a grant Structure has the significant advantage that the protective covers without any special insulating effect breakthrough spacers stored and without such spacers, ζ. B. in the form of folded film wraps, airtight
angeordnet werden können. Diese zellenförmige Unterteilung ist in Abb. ι dargestellt.can be arranged. This cellular subdivision is shown in Fig. Ι.
Ferner können die dünnen Metallfolietrennschichten zur Sicherung des gleichmäßigen Ab-. Standes durch wellenförmige Falten versteiftwerden, wie dies aus der Abb. 2 ersichtlich ist. Das Falten macht die Folie zugleich für ein Abwickeln auf gekrümmte Flächen schmiegsamer. Um den durch hohe Isolierfähigkeit ausgezeichneten Asbest verwerten zu können, wird dieses Material als Asbestzement verwendet. Diese Ausbildung der Erfindung gewährt die Möglichkeit, die erforderliche Standfestigkeit mit einer sehr geringen Stegdicke zu erzielen, und bringt außerdem den Vorteil einer sehr erheblichen Verminderung der Wärmeleitung durch den Steg und einer solchen Kostenersparnis an Isoliermaterial besonders gegenüber den teuren Asbestschnüren mit sich, daß sie die Anwendung zellenförmig angeordneter Asbeststege wirtschaftlich erst ermöglicht.'Furthermore, the thin metal foil release layers to secure the even down. Stiffened by undulating folds, as can be seen from Fig. 2. The folding also makes the film more pliable for unwinding on curved surfaces. In order to be able to recycle the asbestos, which is characterized by its high insulating properties, this material is used as asbestos cement. This embodiment of the invention grants Possibility to achieve the required stability with a very small web thickness, and also has the advantage of a very considerable reduction in heat conduction by the web and such a cost saving on insulating material, especially compared to the expensive asbestos cords mean that they use cellular asbestos bars economically only possible. '
Die Abb. 3 zeigt eine weitere Steganordnung, welche aus geraden Asbestzementstäben und Wellenförmig ausgebildeten Bändern aus z. B. Metallfolie zusammengesetzt ist.Fig. 3 shows another bar arrangement, which is made of straight asbestos cement rods and Wavy bands of z. B. is composed of metal foil.
