Abstract
Description
Die Erfindung betrifft eine beheizbare Rohrleitung.The The invention relates to a heatable pipeline.
Für Rohrleitungen in modernen Großraumflugzeugen (z. B. Airbus A380, Boeing 747) ist aufgrund niedriger Temperaturen in großen Flughöhen eine Beheizung notwendig. Zu diesem Zweck wird entlang der Rohrleitung, die insbesondere aus Stahl oder Titan besteht, eine äußere Heizung in Form einer elektrischen Heizleitung aufgebracht. Nachteilig dabei sind insbesondere die aufwändige Verlegung der Heizleitung sowie deren Gewicht.For Pipelines in modern wide-body aircraft (eg Airbus A380, Boeing 747) is due to low temperatures in large Altitudes require heating. For this purpose is along the pipeline, which consists in particular of steel or titanium, an external heater in the form of an electric Heating cable applied. The disadvantages are in particular the time-consuming laying of the heating cable and its weight.
Aus
der
Aufgabe der Erfindung ist es, eine beheizbare Rohrleitung zu schaffen, die im Vergleich zu den bekannten heizbaren Rohrleitungen gewichtsreduziert ist sowie einen geringeren Aufwand zu ihrer Herstellung erfordert.task The invention is to provide a heated pipe, the weight-reduced compared to the known heatable piping is and requires less effort to produce them.
Diese Aufgabe wird mit dem Gegenstand des Patentanspruchs 1 gelöst. Vorteilhafte Ausführungen sind Gegenstand von Unteransprüchen.These The object is achieved with the subject of claim 1. Advantageous embodiments are the subject of dependent claims.
Erfindungsgemäß besteht die beheizbare Rohrleitung aus einem Kohlenstofffasern enthaltenden Faserverbundwerkstoff. Die Kohlenstofffasern innerhalb der Faserstruktur dienen zusätzlich zu Ihrer Funktion als Strukturelemente auch als Heizele mente für die Beheizung der Rohrleitung. Dies ist möglich, da Kohlenstofffasern (anders als z. B. Glasfasern oder Aramidfasern) elektrisch leitend sind. Die Heizungselemente sind somit unmittelbar in die Struktur der Rohrleitung integriert.According to the invention the heatable pipeline of a carbon fiber containing Fiber composite material. The carbon fibers within the fiber structure serve as structural elements in addition to their function also as heating elements for heating the pipeline. This is possible because carbon fibers (unlike e.g. Glass fibers or aramid fibers) are electrically conductive. The heating elements are thus integrated directly into the structure of the pipeline.
Es ergibt sich somit eine beträchtliche Gewichtsoptimierung, und zwar einerseits durch die Verwendung von leichtem, aber hochfesten Faserverbundmaterial für die Rohrleitung, andererseits dadurch, dass ein separates, d. h. externes Heizelement nicht benötigt wird.It This results in a considerable weight optimization, on the one hand through the use of lightweight, but high-strength Fiber composite material for the pipeline, on the other hand in that a separate, d. H. external heating element not needed becomes.
Die erfindungsgemäße Rohrleitung kann darüber hinaus wesentlich einfacher und kosteneffektiver hergestellt werden, da zusätzliche Arbeitsschritte für die Anbringung des äußeren Heizelements nicht notwendig sind. Die Einbringung des Heizelements erfolgt vielmehr im Rahmen der Herstellung des Faserverbundwerkstoffs selbst, wobei hierbei auf etablierte, automatisierte Herstellungsmethoden der Kunststofftechnik, wie z. B. Flechten oder Wickeln, zurückgegriffen werden kann. Die Herstellung erfolgt somit weitgehend automatisiert und mit hoher Produktivität. Aufgrund der Anforderungen an die Variabilität in der Bauteilgestaltung eignet sich die 3D-Flechttechnik besonders, da dort mit Unterstützung eines Roboterarms die Herstellung von geraden und gekrümmten Rohrabschnitten durchführbar ist.The inventive pipe can about it be made much easier and more cost-effective, because additional work steps for the attachment the outer heating element are not necessary. The introduction of the heating element is rather in the context of Production of the fiber composite itself, in this case on established, automated production methods of plastics technology, such as B. braiding or winding, are used can. The production is thus largely automated and with high productivity. Due to the requirements of the variability in the component design is the 3D braiding technique especially, there with the support of a robotic arm the production of straight and curved pipe sections is feasible.
Weitere Vorteile der erfindungsgemäßen Rohrleitung sind eine gleichmäßige Beheizung der Rohre sowie ein sehr guter Wärmeübergang zu dem zu beheizenden Medium.Further Advantages of the pipe according to the invention are a uniform heating of the pipes as well very good heat transfer to the heated Medium.
Die Erfindung wird anhand konkreter Ausführungsbeispiele unter Bezugnahme auf Figuren näher erläutert. Es zeigen:The Invention is based on specific embodiments below Reference to figures explained in more detail. Show it:
Insgesamt
besteht die gezeigte, beispielhafte Rohrleitung
Der Vorteil einer spiralförmigen Anordnung besteht darin, dass eine einzelne Faser aufgrund ihrer erhöhten Gesamtlänge mehr Wärme in die Rohrleitung abgeben kann. Ein weiterer Vorteil ist die dadurch erreichte gleichmäßige Beheizung mit einer geringen Anzahl von Kohlenstofffasern. Dadurch kann die Effektivität weiter erhöht werden.The advantage of a spiral arrangement is that a single fiber can deliver more heat into the tubing because of its increased overall length. Another advantage is the thus achieved uniform heating with a low number of carbon fibers. This can further increase the effectiveness.
Die
Tatsache, dass die Kohlenstofffasern
Wie
bereits erwähnt, sind in der Ausführung nach
Anders als in der beschriebenen Ausführung kann die Faserstruktur der Rohrleitung auch ausschließlich aus Kohlenstofffasern bestehen.Different as in the described embodiment, the fiber structure the pipeline also exclusively of carbon fibers consist.
Als Fasern können insbesondere Rovings oder Nähgarn verwendet werden. Für die Beheizung sind insbesondere kurzfaserige Nähgarne vorteilhaft, da sie eine homogenere Stromleitung ermöglichen und widerstandsfähiger sind.When Fibers can in particular rovings or sewing thread be used. For the heating are in particular kurzfaserige Sewing threads are advantageous because they provide a more homogeneous power line enable and are more resilient.
Die für die Heizung eingesetzten Kohlenstofffasern werden mit einer Spannungsquelle verbunden. Bei einer Anwendung in einem Flugzeug erfolgt eine elektrische Verbindung mit dessen Bordnetz. Der Anschluss kann z. B. dadurch realisiert werden, in dem eine Ringnut in das Rohr gefräst wird, wodurch die leitenden Fasern freigelegt werden. Anschließend kann durch ein Anschlusselement Spannung auf die als Heizelemente dienenden Kohlenstofffasern gegeben werden. Eine alternative Möglichkeit des Anschlusses ist es, die Kohlenstofffasern aus der Rohrleitung heraustreten zu lassen und sie dann gemeinsam mit einem Quetschring zu verbinden. Dieser kann dann an dem Anschlusselement zum Bordnetz verbunden werden.The For the heating used carbon fibers are with connected to a voltage source. When used in an airplane An electrical connection is made with its electrical system. The connection can z. B. be realized in which an annular groove in the Tube is milled, exposing the conductive fibers become. Subsequently, by a connection element voltage be given to serving as heating elements carbon fibers. An alternative way of connecting it is the Carbon fibers emerge from the pipeline and then combine them together with a squeeze ring. This one can then be connected to the connection element to the electrical system.
Die erfindungsgemäße beheizbare Rohrleitung eignet sich insbesondere für geschlossene Wassersysteme in Transportflugzeugen, z. B. für Bordtoiletten, Frischwassersystem, Grauwassersystem.The Heated pipe according to the invention is suitable especially for closed water systems in transport aircraft, z. B. for on-board toilets, fresh water system, greywater system.
