Solche Strahlungsanordnungen, oder Strahler, sind allgemein bekannt und beispielsweise in der GB-A-2 233 150 beschrieben. Die in dieser Druckschrift gezeigte Infrarotstrahlungsquelle weist ein Hüllrohr aus einem für infrarote Strahlung transparenten Material auf, das einen elektrischen Leiter enthält, der aus Kohlenfasem gebildet ist, die mit einer elektrischen Energieversorgung verbunden sind. Das Hüllrohr ist an seinen Enden gedichtet und kann entweder evakuiert sein oder mit einem Gas, wie beispielsweise Argon, gefüllt sein. Hierdurch werden Strahlungsquellen mit einem schnellen Ansprechverhalten geschaffen, die bei Temperaturen oberhalb von 1.200°C betreibbar sind. Im Übergangsbereich zwischen dem elektrischen Leiter und den aus dem Hüllrohr an dessen Ende herausgeführten Anschlußstiften ist, innerhalb des Hüllrohres, ein metallischer Drahtleiter eingefügt, der spiralförmig gewickelt ist, um die unterschiedlichen Längenausdehnungen insbesondere des Leiters innerhalb des Hüllrohres auszugleichen.Such radiation arrangements, or radiators, are well known and, for example, in GB-A-2 233 150. The infrared radiation source shown in this document has a cladding tube made of a material transparent to infrared radiation, which has an electrical Contains ladder made of carbon fibers with an electric power supply are connected. The cladding tube is sealed at its ends and can either be evacuated be or be filled with a gas such as argon. This will be Radiation sources with a fast response created at temperatures above 1.200 ° C are operable. In the transition area between the electrical conductor and the led out of the cladding tube at the end of the pins is within the Cladding tube, a metallic wire conductor inserted, which is spirally wound around the different ones Length expansions in particular of the conductor within the cladding tube compensate.
Weiterhin beschreibt die DE-A1 44 19 285 eine Strahlungsanordnung, insbesondere einen Infrarotstrahler, mit wenigstens einer flächenhaft ausgebildeten Strahlungsquelle. Die Strahlungsquelle ist ein Carbonband, das in mehreren, zusammenhängenden Teilabschnitten angeordnet ist, wobei die Teilabschnitte an ihren Enden in Auflagen gehalten sind, von denen mindestens die erste und die letzte als Kontakt ausgebildet sind; hierdurch ist diese Strahlungsanordnung auch über längere Zeit temperaturwechselbeständig und weist eine geringe Trägheit auf.Furthermore, DE-A1 44 19 285 describes a radiation arrangement, in particular an infrared radiator, with at least one areal trained radiation source. The radiation source is a carbon ribbon that is in several, related sections is arranged, wherein the sections are held at their ends in conditions, of which at least the first and the last are formed as contact; This makes this radiation arrangement also resistant to temperature changes over a longer period of time and has a low Sluggishness.
Ausgehend von dem vorstehend beschriebenen Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Strahlungsanordnung der eingangs genannten Art so auszubilden, dass sie insbesondere mit kleinen Leuchtrohr- bzw. Hüllrohrdurchmessern, beispielsweise mit Innendurchmessern im Bereich unterhalb von 12 mm, aufgebaut werden kann, wobei gleichzeitig gewährleistet ist, dass Längenänderungen in der Strahlungsquelle kompensiert werden können.Based on the above-described prior art, the present invention the object, a radiation arrangement of the type mentioned in such a way, that they in particular with small Leuchtrohr- or Hüllrohrdurchmessern, for example with inner diameters in the range below 12 mm, can be constructed, wherein At the same time it is ensured that length changes in the radiation source are compensated can be.
Gelöst wird diese Aufgabe, ausgehend von einer Strahlungsanordnung mit den eingangs genannten Merkmalen, dadurch, dass das Zwischenteil aus Molybdän-Blech gebildet ist, das mindestens einen Faltungsabschnitt mir zwei Knickstellen quer zur Längsachse aufweist.This problem is solved, starting from a radiation arrangement with the aforementioned Characteristics, characterized in that the intermediate part is formed of molybdenum sheet, the Has at least one folding section with two kinks transverse to the longitudinal axis.
Es hat sich gezeigt, dass insbesondere bei der Herstellung von Strahlungsanordnungen mit kleineren Leuchtrohrdurchmessem, beispielsweise mit Durchmessern von 9 mm im Innenraum, ein Federelement aus spiralförmig gewickeltem Draht, wie es derzeit im Stand der Technik eingesetzt wird, nicht verwendbar ist, da bei kleineren Hüllrohrdurchmessem (kleiner 12 mm innen) eine Spiralfeder aus einer Molybdän-Litze, die wegen der hohen Strombelastung einen entsprechend angepaßten Querschnitt haben muß, unelastischer wird. Beim Quetschen des Hüllrohrs an seinen Enden würde dann auch die Gefahr bestehen, dass die Molybdän-Dichtfolie, die üblicherweise im Bereich der Durchführung des Strahlungsbandes um dieses herum gelegt wird, durch eine zu hohe Zugkraft reißt. Für die Kompensation der Längendehnung des Strahlungsbandes bzw. der Strahlungsquelle wird daher, gemäß der Erfindung, eine Maßnahme ergriffen, die vorsieht, als Element zur Kompensation der Längenänderung ein Molybdän-Blech einzusetzen, das mindestens einen Faltungsabschnitt aufweist, der ausreichend ist, um die auftretenden Längenänderungen zu kompensieren. Es hat sich gezeigt, dass mit einem so gefalteten Molybdän-Blech Strahler, insbesondere Carbonstrahler, mit sehr kleinem Leucht- bzw. Hüllrohrdurchmesser hergestellt werden können, da mit dem Molybdän-Blech die hohen Strombelastungen, trotz des geringen, zur Verfügung stehenden Innenquerschnitts des Strahlers, aufgenommen werden können, da das Molybdän-Blech unter der Ausnutzung des vollen Innendurchmessers des Hüllrohrs dimensioniert werden kann.It has been shown that in particular in the manufacture of radiation arrangements with smaller Leuchtrohrdurchmessem, for example, with diameters of 9 mm in the interior, a spring element made of spirally wound wire, as currently known in the art is not usable, since with smaller Hüllrohrdurchmessem (less than 12 mm inside) a spiral spring made of a molybdenum wire, due to the high current load must have a correspondingly adapted cross-section, is inelastic. When squeezing the cladding tube at its ends would then also risk that the molybdenum sealing foil, usually in the area of the implementation of the radiation band around this around is torn by a too high tensile force. For compensation of elongation of the radiation band or the radiation source is therefore, according to the invention, a Measure taken, which provides as a compensation element for the change in length, a molybdenum sheet use, which has at least one folding section, the sufficient is to compensate for the occurring length changes. It has been shown that with a so-folded molybdenum-sheet radiator, especially carbon radiator, with very small Luminous or cladding tube diameter can be produced because with the molybdenum sheet the high current loads, despite the small, available inner cross section of the Strahlers, can be included as the molybdenum sheet under the exploitation of the full inner diameter of the cladding tube can be dimensioned.
Um zum einen eine ausreichende mechanische Stabilität zu erzielen und zum anderen hohen Strombelastungen gerecht zu werden, sollte das Molybdän-Blech eine Dicke im Bereich vom 0,07 bis 0,1 mm aufweisen, mit einer bevorzugten Breite des Molybdän-Blechs im Bereich von 0,5 bis 0,7 mm pro 1A Strombelastung.In order to achieve sufficient mechanical stability on the one hand and high on the other hand To meet current loads, the molybdenum sheet should have a thickness in the range of 0.07 to 0.1 mm, with a preferred width of the molybdenum sheet in the range of 0.5 to 0.7 mm per 1A current load.
Darüber hinaus hat es sich insbesondere auch in Hinblick auf die erforderliche Elastizität als zweckdienlich erwiesen, das Verhältnis von Breite zu Höhe des gefalteten Molybdän-Blechs im Bereich von 1 : 0,5 bis 1: 1, vorzugsweise von etwa 1 : 0,75, auszuwählen.In addition, it has in particular with regard to the required elasticity as expedient, the ratio of width to height of the folded molybdenum sheet in Range from 1: 0.5 to 1: 1, preferably from about 1: 0.75.
Die Strahlungsanordnung, wie sie angegeben ist, eignet sich insbesondere für Innendurchmesser des Hüllrohrs, die bei weniger als 12 mm liegen.The radiation arrangement, as indicated, is particularly suitable for inner diameter of the cladding tube, which are less than 12 mm.
Um die Elastizität zu erhöhen, insbesondere dann, wenn Strahlungsanordnungen mit sehr langen Hüllrohren aufgebaut werden sollen, kann der Faltungsabschnitt mit mehreren Knickstellen versehen werden, die, in Achsrichtung des Hüllrohrs gesehen, zick-zack- oder harmonika-artig hintereinander angeordnet sind. Zum Beispiel liegt bei einer Länge der Strahlungsquelle im Bereich von 400 bis 1000 mm die Anzahl der Faltungen bzw. Knickstellen vorzugsweise bei mindestens 10. Falls Längen der Strahlungsquelle im Bereich von > 1000 mm erforderlich sind, sollte die Anzahl der Faltungen bzw. Knickstellen mindestens 12 betragen.To increase the elasticity, especially when radiation arrangements with very long Cladding tubes are to be constructed, the folding section with multiple kinks be provided, which, seen in the axial direction of the cladding tube, zig-zag or harmonica-like arranged one behind the other. For example, the length of the radiation source is one in the range of 400 to 1000 mm, the number of folds or kinks preferably at at least 10. If length of the radiation source in the range of> 1000 mm is required should the number of folds or kinks be at least 12.
Ein Faltungsabschnitt, wie er eingesetzt werden soll, kann auch im Bereich von beiden Anschlußenden der Strahlungsquelle, die mit den jeweiligen, durch die Quetschung am Ende des Hüllrohrs nach außen geführten Anschlußstiften verbunden werden, angeordnet sein.A folding section, as it should be used, can also be in the area of both terminal ends the source of radiation, with the respective, by the pinch at the end of the Cladding tube outwardly guided pins are connected, be arranged.
Besonders bevorzugt ist die Ausbildung eines solchen Faltungsabschnitts mit mindestens zwei Knickstellen quer zur Längsachse des Hüllrohrs in Verbindung mit einem Carbonband als Strahlungsquelle.Particularly preferred is the formation of such a folding section with at least two Kinks transverse to the longitudinal axis of the cladding tube in conjunction with a carbon ribbon as Radiation source.
Um eine einfache, allerdings dennoch sehr haltbare Verbindung des Faltungsabschnitts mit dem Anschlußstift einerseits und mit der Strahlungsquelle andererseits zu erzielen, sollte vorzugsweise eine Widerstandsschweißung eingesetzt werden.To a simple, but still very durable connection of the folding section with to achieve the pin on the one hand and with the radiation source on the other hand, should preferably a resistance welding can be used.
