Abstract
Description
Die Erfindung bezieht sich auf Heizdrahtanordnung mit einem flächigen Trägersubstrat, auf dessen wenigstens einen Oberseite ein Heizdraht derart vorgesehen ist, dass wenigstens Teilbereiche des Trägersubstrates möglichst homogen beheizbar sind, mit einem, mit einer Oberseite des Trägersubstrates in Wirkverbindung tretenden Haftvermittlers, durch den das Trägersubstrat mittel- oder unmittelbar mit einer Oberfläche eines zu beheizenden Gegenstandes in einen innigen und dauerhaften Flächenkontakt bringbar ist.The invention relates to a heating wire arrangement with a planar carrier substrate, on whose at least one upper side a heating wire is provided such that at least portions of the carrier substrate are heated as homogeneously as possible, with a, with an upper side of the carrier substrate in operative connection passing adhesive through which the carrier substrate medium - Or directly with a surface of an object to be heated in an intimate and permanent surface contact can be brought.
Heizdrahtanordnungen der vorstehend genannten Gattung stellen Flächenheizelemente dar, die einen großflächigen Wärmeübergang zu einem zu beheizenden Gegenstand, der mit dem Flächenheizelement in thermischem Kontakt steht, bewirken. Bekannte Flächenheizdrahtanordnungen bestehen aus einer hitzebeständigen Trägerfolie, deren Folienstrukturen Temperaturen von bis zu 600 bis 700° C widerstehen. Auf der Trägerfolie ist vorzugsweise meanderförmig ein Heizdraht derart aufgebracht, dass der Heizdraht nahezu die gesamte Trägerfolienoberfläche mit gleichbeabstandeten Mäanderabständen überdeckt.Heizdrahtanordnungen the above-mentioned type represent surface heating, which is a large-scale heat transfer to a heated object, which is in thermal contact with the surface heating effect. Known Flächenheizdrahtanordnungen consist of a heat-resistant carrier film whose film structures withstand temperatures of up to 600 to 700 ° C. On the carrier film, a heating wire is preferably applied in a meandering fashion in such a way that the heating wire covers almost the entire carrier film surface with equidistantly spaced meander intervals.
Aus Gründen mechanischen Schutzes sowie zur elektrischen Isolierung ist der Heizdraht von einer zweiten Folienschicht überdeckt, die mittels üblicher Klebetechnik mit der Trägerfolie in innigen Kontakt gebracht wird und den Heizdraht einschließt vollständig. Hierbei sind vorzugsweise Trägerfolie und Abdeckfolie aus dem gleichen hitzebeständigen Kunststoffmaterial gefertigt.For reasons of mechanical protection and for electrical insulation of the heating wire is covered by a second film layer, which is brought into intimate contact by means of conventional adhesive bonding with the carrier film and includes the heating wire completely. In this case, preferably carrier film and cover are made of the same heat-resistant plastic material.
Flächige Heizdrahtanordnungen können aufgrund ihrer Flexibilität auf ebenen oder gekrümmten Körperoberflächen aufgebracht werden, die es gilt, nahezu homogen über ihre gesamte Körperfläche zu beheizen. Beispielsweise können auf diese Weise Gefäßheizungen realisiert werden. Hierzu sind an den Gefäßaussenwänden die flächigen Heizdrahtanordnungen entsprechend angebracht.Because of their flexibility, flat heating wire arrangements can be applied to flat or curved body surfaces that are required to heat almost homogeneously over their entire body surface. For example, vessel heaters can be realized in this way. For this purpose, the flat Heizdrahtanordnungen are attached to the outer walls of the vessel accordingly.
Aus Gründen eines möglichst guten Wärmeüberganges zwischen der flächigen Heizdrahtanordnung und dem flächig zu beheizenden Gegenstand sollte der Flächenkontakt zwischen der Heizdrahtanordnung und der zu beheizenden Oberfläche möglichst innig und ohne Unterbrechungen sein, zumal bereits kleinste Lufteinschlüsse zwischen der Trägerfolie und der Oberfläche des Gegenstandes zum einen den Wärmeübergang entscheidend verschlechtern und zum anderen infolge des verschlechterten Wärmeüberganges eine lokale Überhitzung des Heizdrahtes und der Trägerfolie bewirken, die die flächige Heizdrahtanordnung irreversibel zu schädigen vermag.For reasons of the best possible heat transfer between the flat Heizdrahtanordnung and the surface to be heated object surface contact between the Heizdrahtanordnung and the surface to be heated should be as intimately and without interruptions, especially since even the smallest air bubbles between the support film and the surface of the article on the one hand the heat transfer decisively worsen and cause on the other hand, as a result of the deteriorated heat transfer, a local overheating of the heating wire and the carrier film, which is able to irreversibly damage the planar heating wire arrangement.
Üblicherweise wird die Trägerfolie über eine Klebstoffschicht mit der zu beheizenden Oberfläche in innigen Kontakt gebracht. Um die vorstehend genannten Lufteinschlüsse weitgehend auszuschließen, bedarf es besonderer Sorgfalt. Bereits kleinste Unebenheiten oder Materialüberdehnungen innerhalb der Trägerfolie führen jedoch unvermeidbar zu den ungewollten Lufteinschlüssen. Auch ist es nahezu unvermeidbar, an gekrümmt verlaufenden Oberflächen die Heizdrahtfolienanordnung flächig auf die Oberflächenkontur in der gewünschten Weise aufzukleben. Hinzukommt, dass sich beim Heizbetrieb Gase bilden können, die zwischen der Trägerfolie und der zu beheizenden Oberfläche eingefangen sind. Aber nicht nur zwischen der Trägerfolie und der zu beheizenden Oberfläche, sondern auch zwischen der Trägerfolie und der Abdeckfolie können sich derartige Gaseinschlüsse ausbilden. Derartige Gasbildungen können aus temperaturbedingten Ausgasprozessen aus der Trägerfolie bzw. der Abdeckfolie selbst oder dem Oberflächenmaterial des zu beheizenden Gegenstandes herrühren.Usually, the carrier film is brought into intimate contact with the surface to be heated via an adhesive layer. In order to largely exclude the above-mentioned air pockets, special care is required. Already However, smallest bumps or material overstresses within the carrier film inevitably lead to the unwanted air inclusions. Also, it is almost unavoidable to stick on curved surfaces running the Heizdrahtfolienanordnung surface on the surface contour in the desired manner. In addition, gases can form during heating operation, which are trapped between the carrier film and the surface to be heated. But not only between the carrier film and the surface to be heated, but also between the carrier film and the cover, such gas inclusions can form. Such gas formations can result from temperature-related outgassing processes from the carrier film or the cover film itself or the surface material of the object to be heated.

Der Erfindung liegt die Aufgabe zugrunde, eine Heizdrahtanordnung mit einem flächigen Trägersubstrat, auf dessen wenigstens einen Oberseite ein Heizdraht derart vorgesehen ist, dass wenigstens Teilbereiche des Trägersubstrates möglichst homogen beheizbar sind, mit einem, mit einer Oberseite des Trägersubstrates in Wirkverbindung tretenden Haftvermittlers, durch den das Trägersubstrat mittel- oder unmittelbar mit einer Oberfläche eines zu beheizenden Gegenstandes in einen innigen und dauerhaften Flächenkontakt bringbar ist, derart weiterzubilden, dass das Auftreten von Luft- oder Gaseinschlüssen zwischen der Oberfläche des zu beheizenden Gegenstandes und des Trägersubstrates weitgehend ausgeschlossen werden kann bzw. dass bereits bei der Klebung vorhandene Lufteinschlüsse ohne Beschädigung des Trägersubstrates sowie der Heizdrahtanordnung leicht beseitigt werden können. Überdies soll die erfindungsgemäße Heizdrahtanordnung einen sicheren und langlebigen Betrieb gewährleisten, bei dem ein lokales Überhitzen aufgrund von Wärmestaubildungen innerhalb der Heizdrahtanordnung vermieden werden kann. Die erfindungsgemäßen Maßnahmen sollen für den Anwender keinen oder zumindest einen nur geringen zusätzlichen Aufwand sowohl für die Montage als auch für die Beseitigung der möglicherweise auftretenden Luft- oder Gaseinschlüsse bieten. Die Maßnahmen sollen überdies günstig in der Herstellung sein, so dass die herstellungsbedingten Kosten für die gesamte Heizdrahtanordnung nahezu unbeeinflusst bleiben.The invention is based on the object, a Heizdrahtanordnung with a flat carrier substrate, on whose at least one upper side a heating wire is provided such that at least portions of the carrier substrate are heated as homogeneously as possible, with one, with an upper side of the carrier substrate in operative connection passing through the bonding agent the support substrate medium or directly with a surface of an object to be heated in an intimate and permanent surface contact can be brought, so educate, that the occurrence of air or gas inclusions between the surface to be heated Object and the carrier substrate can be largely excluded or that already existing in the gluing air pockets can be easily removed without damaging the carrier substrate and the Heizdrahtanordnung. Moreover, the Heizdrahtanordnung invention should ensure a safe and durable operation in which a local overheating can be avoided due to heat accumulation within the Heizdrahtanordnung. The measures according to the invention are intended to offer the user no or at least only a small additional expense both for the assembly and for the elimination of possibly occurring air or gas inclusions. The measures should also be low in production, so that the production-related costs for the entire heating wire arrangement remain almost unaffected.
Die Lösung der der Erfindung zugrundeliegenden Aufgabe ist im Anspruch 1 oder 4 angegeben. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche sowie der Beschreibung unter Bezugnahme auf die Figuren zu entnehmen.The solution of the problem underlying the invention is specified in
Erfindungsgemäß ist die Heizdrahtanordnung gemäß dem Oberbegriff des Anspruchs 1 derart weitergebildet, dass zwischen dem Trägersubstrat und der Oberfläche des Gegenstandes wenigstens ein linienförmiger Bereich vorgesehen ist, der eine Unterbrechung im Flächenkontakt zwischen dem Trägersubstrat und der Oberfläche des Gegenstandes darstellt und sich wenigstens bis zu einem Rand des Flächenkontaktes zwischen dem Trägersubstrat und der Oberfläche des Gegenstandes erstreckt und als Entlüftungskanal dient, und dass zwischen dem Trägersubstrat und der Oberfläche des Gegenstandes wenigstens ein Abstandshalterelement eingebracht ist, das die Unterbrechung im Flächenkontakt bewirkt.According to the heating wire arrangement according to the preamble of
Der Erfindung liegt die Idee zugrunde, zwischen der folienartig ausgebildeten Heizdrahtanordnung und der zu beheizenden Oberfläche, auf die das, vorzugsweise mit einem Haftvermittler versehene, folienartig ausgebildete Trägersubstrat ganzflächig aufgebracht wird, eine Art von Entlüftungskanälen einzubringen, über die zwischen dem Trägersubstrat und der Oberfläche des Gegenstandes eingeschlossene Luft- oder Gasblasen gezielt seitlich abgeführt werden können. Durch sogenannten Entlüftungskanäle, die ihrerseits eine gezielte Unterbrechung im Flächenkontakt zwischen dem Trägersubstrat und der Oberfläche des Gegenstandes darstellen, können Luft- oder Gaseinschlüsse entweichen, die sich auch vom Entlüftungskanal beabstandet gebildet haben, durch entsprechend manuelles Andrücken gegen die Lufteinschlüsse in Richtung der Unterbrechungen bzw. Entlüftungskanäle wandern bis sie die Unterbrechungen erreicht haben.The invention is based on the idea between the foil-like heating wire arrangement and the surface to be heated, to which the, preferably with a bonding agent provided, film-like carrier substrate is applied over the entire surface, to introduce a type of venting channels, can be selectively removed laterally over the trapped between the carrier substrate and the surface of the article air or gas bubbles. By so-called venting channels, which in turn represent a targeted interruption in the surface contact between the carrier substrate and the surface of the object, air or gas inclusions can escape, which have also formed spaced from the vent channel, by appropriately manual pressing against the air inclusions in the direction of interruptions or Venting channels travel until they have reached the breaks.
Andererseits können während des Heizbetriebes durch lokal auftretende Gasbildungen Luft- oder Gaseinschlüsse zwischen dem Trägersubstrat und der zu beheizenden Oberfläche entstehen. Auch derartige Gaseinschlüsse können in besagter Weise durch manuelles Verpressen in Richtung der vorgesehenen Unterbrechungen bewegt werden. Es stellte sich jedoch heraus, dass sich durch thermische Gasausdehnung die Gaseinschlüsse selbständig über die Entlüftungskanäle beseitigen. Nur bei besonders hartnäckigen, d.h. großen Gaseinschlüssen ist ein manuelles verpressen notwendig.On the other hand, air or gas inclusions may form between the carrier substrate and the surface to be heated during the heating operation due to locally occurring gas formation. Also, such gas inclusions can be moved in said manner by manual compression in the direction of the intended interruptions. However, it turned out that thermal gas expansion eliminates the gas inclusions automatically via the venting channels. Only for particularly stubborn, i. Large gas inclusions require manual compression.
Erfindungsgemäß werden die Unterbrechungen durch gezieltes Einbringen von Abstandshalteelementen gebildet, die beispielsweise in Form eines Drahtes ausgebildet sind, der sich vorzugsweise von einer Seite des Flächenkontaktes zu einer anderen Seite des Flächenkontaktes linienhaft erstreckt. Je nach Größe des Flächenkontaktes zwischen dem Trägersubstrat und der zu beheizenden Oberfläche ist es vorteilhaft, eine Vielzahl durch den Draht vorgegebene Entlüftungskanäle zu bilden, so dass eine Vielzahl in etwa gleich beabstandeter parallel verlaufender Drähte zwischen dem Trägersubstrat und der Oberfläche des Gegenstandes vorgesehen sind.According to the invention, the interruptions are formed by targeted introduction of spacer elements, which are formed for example in the form of a wire, which preferably extends linearly from one side of the surface contact to another side of the surface contact. Depending on the size of the surface contact between the carrier substrate and the surface to be heated, it is advantageous to form a plurality of predetermined through the wire ventilation channels, so that a plurality of approximately equally spaced parallel wires between the carrier substrate and the surface of the article are provided.
Alternativ oder in Kombination zur Verwendung eines Abstandshaltelementes in Form eines Drahtes ist es auch möglich, die Unterbrechung durch eine, in der Trägerfolie eingebrachte Prägung zu erhalten, die beispielsweise in Form einer V-förmigen Nut ausgebildet ist. Beim Aufbringen der Trägerfolie auf die Oberfläche des zu beheizenden Gegenstandes ist dabei zu beachten, dass die Prägung der Trägerfolie nicht in innigen Oberflächenkontakt gebracht wird, so dass die Nutform erhalten bleibt.Alternatively or in combination with the use of a spacer element in the form of a wire, it is also possible to obtain the interruption by means of an embossment introduced in the carrier film, for example in the form of a V-shaped groove is trained. When applying the carrier film to the surface of the object to be heated, it should be noted that the embossing of the carrier film is not brought into intimate surface contact, so that the groove shape is maintained.
Zur Vermeidung von sich zwischen der Träger- und Abdeckfolie ausbildenden Gaseinschlüssen, die sich während der Heizphase aus den vorstehend genannten Gründen auch innerhalb der Heizdrahtanordnung bilden können, ist es darüberhinaus besonders vorteilhaft, dass die zwischen der Trägerfolie und der Abdeckfolie eingebrachten Heizdrähte zumindest eine der beiden Folien seitlich überragen, so dass sich längs der Heizdrähte ausbildende Gasansammlungen zwischen beiden Folien über die Seitenkanten der Heizdrahtanordnung entweichen können.To avoid gas inclusions forming between the carrier and cover films, which can also form within the heating wire arrangement during the heating phase for the abovementioned reasons, it is furthermore particularly advantageous that the heating wires introduced between the carrier film and the cover film are at least one of the two Overhang laterally foils, so that along the heating wires forming gas accumulations can escape between the two foils on the side edges of the Heizdrahtanordnung.
