Description

Die Erfindung betrifft eine elektrische Heizeinrichtung, insbesondere für ein Kraftfahrzeug nach dem Oberbegriff des Patentanspruches 1, bekannt durch die DE-A 197 32 010.The invention relates to an electrical heating device, in particular for a Motor vehicle according to the preamble of claim 1, known by DE-A 197 32 010.

Elektrische Heizeinrichtungen, wie sie durch die DE-A 197 32 010 bekannt wurden, sind insbesondere für Kraftfahrzeuge mit verbrauchsoptimierten Motoren bestimmt, bei welchen aufgrund des hohen thermischen Wirkungsgrades nicht genügend Heizleistung zur Verfügung steht. Daher werden die Heizungsanlagen zusätzlich mit einer elektrischen Heizeinrichtung, einem so genannten Zuheizer, ausgerüstet. Dieser Zuheizer besteht aus einem Heizblock mit mehreren parallel zueinander angeordneten elektrischen Heizelementen, zwischen denen Wellrippen zur Verbesserung des Wärmeübergangs gegenüber der Luft angeordnet sind. Die Heizelemente bestehen aus zwei Kontaktblechen, zwischen denen PTC-Elemente angeordnet sind. Eines der Kontaktbleche weist jeweils ein elektrisches Anschlusselement, z. B. in Form eines abgewinkelten Endabschnittes des Bleches auf, über welches das Kontaktblech mit einem Pol einer elektrischen Versorgung verbunden ist. Vielfach sind diese elektrischen Anschlusselemente zur Verbesserung des Übergangswiderstandes mit einem Flachstecker verbunden, der seinerseits in eine Steckhülse gesteckt wird, wie sie durch DIN 46 247 bekannt ist. Damit ergibt sich eine so genannte Flachsteckverbindung mit großer Kontaktsicherheit und geringerem Übergangswiderstand - allerdings muss der Flachstecker als zusätzliches Teil mit dem elektrischen Anschlusselement verbunden, d. h. vernietet werden. Dies bedeutet zusätzlichen Arbeitsaufwand, Gewicht und Kosten.Electric heaters, as known from DE-A 197 32 010 were, in particular, for motor vehicles with consumption-optimized Engines determines where due to the high thermal efficiency not enough heating power is available. Therefore, the Heating systems in addition with an electric heater, a so mentioned heater, equipped. This heater consists of a heating block with a plurality of mutually parallel electrical heating elements, between which corrugated fins to improve the heat transfer are arranged opposite the air. The heating elements consist of two contact plates, between which PTC elements are arranged. One the contact plates each have an electrical connection element, for. B. in the form of an angled end portion of the sheet over which the contact plate is connected to a pole of an electrical supply. In many cases, these electrical connection elements for improving the Contact resistance associated with a tab, in turn is inserted into a socket, as it is known by DIN 46 247. In order to results in a so-called flat connector with great contact reliability and lower contact resistance - but the tab must as an additional part connected to the electrical connection element, d. H. be riveted. This means extra work, weight and costs.

Es ist Aufgabe der vorliegenden Erfindung, bei einer Heizeinrichtung der eingangs genannten Art die elektrischen Kontaktanschlüsse zu verbessern, insbesondere hinsichtlich ihrer Kosten, ihres Gewichts und ihres fertigungstechnischen Aufwandes zu reduzieren.It is an object of the present invention, in a heating device of the type mentioned above to improve the electrical contact connections, in particular with regard to their costs, their weight and their manufacturing technology Reduce effort.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Erfindungsgemäß sind die aus einer Aluminiumlegierung oder aus Messing hergestellten Kontaktbleche mit einer Kontaktzunge versehen, die mit einem Material hoher elektrischer Leitfähigkeit beschichtet ist. Dadurch wird der Vorteil erreicht, dass ein Flachstecker herkömmlicher Art entfallen kann und die Kontaktzunge des Kontaktbleches direkt mit der Stromversorgung verbunden werden kann. Das Kontaktblech besteht nur noch aus einem Teil und ist damit einfacher herstellbar und montierbar. Dadurch wird das Heizelement und damit auch die gesamte Heizeinrichtung leichter und billiger. Darüber hinaus ergibt sich aufgrund der elektrisch gut leitenden Beschichtung ein geringer Übergangswiderstand der Kontaktverbindung und damit ein geringer Spannungsabfall zwischen der Spannungsquelle und dem Kontaktblech. Unter der erfindungsgemäßen Heizeinrichtung ist insbesondere ein Heizblock mit elektrischen Heizelementen mit PTC-Elementen zu verstehen, wobei die PTC-Elemente aus Keramik oder Kunststoff mit PTC-Effekt bestehen können. Darüber hinaus kann der Heizblock bzw. die elektrische Heizeinrichtung auch andere, d. h. ähnliche Baugruppen aufweisen, die ebenfalls aus Kontaktblechen und Zwischenelementen sowie Wärmetauschelementen, z. B. in Form von Wellrippen zusammengesetzt sind. Solche Baugruppen weisen z. B. keine Heizelemente, sondern so genannte standardisierte Funktionselemente gemäß der älteren deutschen Anmeldung mit dem Aktenzeichen 102 08 152 auf. Demnach sind Kontaktbleche mit erfindungsgemäß beschichteten Kontaktzungen nicht nur für Baugruppen des Heizblockes mit Heizelementen, sondern auch mit ähnlichen Funktionselementen anwendbar. This object is solved by the features of claim 1. According to the invention are made of aluminum alloy or brass made contact plates provided with a contact tongue, which with a Material of high electrical conductivity is coated. This will be the Advantage achieved that a flat plug conventional type can be omitted and the contact tongue of the contact plate connected directly to the power supply can be. The contact plate consists of only one part and is thus easier to produce and assemble. This will cause the heating element and thus the entire heating easier and cheaper. In addition, due to the good electrical conductivity coating a low contact resistance of the contact connection and thus a low voltage drop between the voltage source and the contact plate. Under the heating device according to the invention is in particular a Heating block with electric heating elements with PTC elements to understand where the PTC elements are made of ceramic or plastic with PTC effect can. In addition, the heating block or the electric heater others, d. H. have similar assemblies, which also contact plates and intermediate elements and heat exchange elements, z. B. are composed in the form of corrugated ribs. Such assemblies have z. B. no heating elements, but so-called standardized Function elements according to the earlier German application with the File number 102 08 152. Accordingly, contact sheets are according to the invention coated contact tongues not only for modules of the heating block with heating elements, but also with similar functional elements applicable.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. Eine Beschichtung mit hoher elektrischer Leitfähigkeit kann bevorzugt durch eine Verzinnung der Kontaktzunge oder auch durch eine Beschichtung mit Kupfer oder Silber erzielt werden. Vorteilhafterweise ist die Kontaktzunge in ihrer Form und ihren Abmessungen wie ein genormter Flachstecker ausgebildet, sodass sie zusammen mit einer genormten Steckhülse, beispielsweise nach DIN 46 247, Teil einer Flachsteckerverbindung sein kann. Damit ist einerseits eine normgerechte Gestaltung des Kontaktanschlusses, jedoch andererseits eine verbilligte und leichtere Ausführung für eine Steckverbindung geschaffen.Advantageous embodiments of the invention will become apparent from the dependent claims. A coating with high electrical conductivity may be preferred by tinning the contact tongue or by a coating can be achieved with copper or silver. Advantageously, the Contact tongue in its shape and dimensions as a standardized Flat plug designed so that they together with a standard receptacle, For example, according to DIN 46 247, part of a flat connector can be. This is on the one hand a standard design of the contact terminal, but on the other hand a cheaper and lighter version created for a plug connection.

Fig. 1 zeigt eine elektrische Heizeinrichtung 1, welche als Zusatzheizung zum Einbau in eine nicht dargestellte Heizungs- oder Klimaanlage eines Kraftfahrzeuges verwendbar ist. Diese Heizeinrichtung 1 weist einen Einbaurahmen 2 auf, welcher einen Heizblock 3, bestehend aus Heizelementen 4, Wellrippen 5 und so genannten standardisieren Funktionselementen 6 besteht. Ein solcher Aufbau eines Heizblockes ist in der älteren deutschen Anmeldung mit dem Aktenzeichen 102 08 152.2 beschrieben - auf den Offenbarungsgehalt dieser älteren Anmeldung wird hiermit Bezug genommen, und der Gegenstand dieser älteren Anmeldung 102 08 152.2 wird vollumfänglich in die Beschreibung dieser Anmeldung aufgenommen. D. h., der Heizblock 3, besteht nicht nur aus den bekannten Heizelementen 4, sondern auch aus zusätzlichen Funktionselementen 6, die ähnlich aufgebaut sind. Fig. 1 shows an electric heater 1, which is used as additional heating for installation in a heating or air conditioning system of a motor vehicle, not shown. This heating device 1 has a mounting frame 2, which consists of a heating block 3, consisting of heating elements 4, corrugated fins 5 and so-called standardizing functional elements 6. Such a structure of a heating block is described in the earlier German application with the file reference 102 08 152.2 - the disclosure of this earlier application is hereby incorporated by reference, and the subject of this earlier application 102 08 152.2 is fully incorporated into the description of this application. D. h., The heating block 3, consists not only of the known heating elements 4, but also of additional functional elements 6, which are similarly constructed.

Der Einbaurahmen 2 weist in seinem oberen Bereich einen Befestigungsflansch 7 und ein Steckergehäuse 8 auf. Die Heizeinrichtung 1 kann in einen nicht dargestellten Luftströmungskanal einer Heizungsanlage eingesetzt und dort mittels des Befestigungsflansches 7 befestigt und abgedichtet werden. Die Stromversorgung der Heizelemente 4 erfolgt über einen nicht dargestellten Stecker, der in das Steckergehäuse 8 eingesetzt wird.The mounting frame 2 has a mounting flange in its upper region 7 and a connector housing 8. The heater 1 may be in a not shown air flow duct of a heating system used and be fastened and sealed there by means of the mounting flange 7. The power supply of the heating elements 4 via a not shown Plug which is inserted into the connector housing 8.

Fig. 2 zeigt eine Einzelheit X aus Fig. 1, d. h. ein teilweise dargestelltes Heizelement 4 mit beiderseits angeordneten Wellrippen 5. Das Heizelement 4 besteht aus zwei unterschiedlich gepolten Kontaktblechen 9, 10, zwischen denen sich in elektrisch und thermisch leitender Verbindung ein PTCelement 11 befindet. Pro Heizelement 4 sind mehrere PTC-Elemente 11 über deren Länge verteilt angeordnet und in bekannter Weise zwischen den Kontaktblechen 9, 10 gehalten. Die Außenseiten der Kontaktbleche 9, 10 stehen in wärmeleitender und elektrischer Verbindung mit den Wellrippen 5, welche zur Vergrößerung der Wärmeaustauschfläche dienen und somit Wärmetauschelemente bilden. Das PTC-Element 11 besteht in der Regel aus einem Keramikwerkstoff, es ist jedoch auch möglich, anstelle des Keramikelementes einen Kunststoff mit PTC-Effekt zu Heizzwecken zu verwenden. 2 shows a detail X of FIG. 1, ie a partially shown heating element 4 with corrugated fins 5 arranged on both sides. The heating element 4 consists of two differently polarized contact plates 9, 10, between which a PTC element 11 is located in electrically and thermally conductive connection , Per heating element 4, a plurality of PTC elements 11 are distributed over the length thereof and held in a known manner between the contact plates 9, 10. The outer sides of the contact plates 9, 10 are in heat-conducting and electrical connection with the corrugated fins 5, which serve to increase the heat exchange surface and thus form heat exchange elements. The PTC element 11 is usually made of a ceramic material, but it is also possible to use a plastic with PTC effect for heating purposes instead of the ceramic element.

Fig. 3 zeigt einen Schnitt längs der Linie III-III durch das PTC- Element 11, die Kontaktbleche 9, 10 und die Wellrippen 5 in Fig. 2. Die Luftströmungsrichtung ist durch einen Pfeil L angezeigt; eine Durchströmung in entgegengesetzter Richtung gemäß einem gestrichelten Pfeil L' ist ebenso möglich. Die durch Bestromung des PTC-Elementes 11 erzeugte Wärme wird - wie aus dem Stand der Technik bekannt - über die Kontaktbleche 9, 10 in die Wellrippen 5 geleitet und über diese an die überströmende Luft abgegeben, die dadurch erwärmt und zur Beheizung des Fahrgastraumes herangezogen wird. Fig. 3 shows a section along the line III-III through the PTC element 11, the contact sheets 9, 10 and the corrugated fins 5 in Fig. 2. The air flow direction is indicated by an arrow L; a flow in the opposite direction according to a dashed arrow L 'is also possible. The heat generated by energizing the PTC element 11 is - as known from the prior art - passed through the contact plates 9, 10 in the corrugated fins 5 and delivered through this to the overflowing air, which is thereby heated and used to heat the passenger compartment ,

Fig. 4 zeigt eines der beiden Kontaktbleche 9, 10, welches hier als vollständiges Einzelteil 12 dargestellt ist. Das Kontaktblech 12 ist als Blechstreifen ausgebildet und aus einer Aluminiumlegierung oder aus Messing hergestellt, ebenso wie die Wellrippen 5 (vgl. Fig. 1 bis 3). Das Kontaktblech 12 weist eine Länge I und eine Breite b auf - in diesem Bereich sind die hier nicht dargestellten PTC-Elemente 11 (oder funktionell ähnliche Elemente) angeordnet. Das in der Zeichnung links gelegene Ende des Kontaktbleches 12 weist eine Kontaktzunge 13 auf, die eine Breite a aufweist, welche geringer als die Breite b des Kontaktbleches 12 ist. Kontaktblech 12 und Kontaktzunge 13 sind einstückig aus einem Blech gestanzt. Die Kontaktzunge 13 weist in etwa mittiger Lage eine kreisförmige Öffnung 14 auf. Fig. 4 shows one of the two contact sheets 9, 10, which is shown here as a complete item 12. The contact plate 12 is formed as a metal strip and made of an aluminum alloy or brass, as well as the corrugated fins 5 (see Fig. 1 to 3). The contact plate 12 has a length I and a width b - in this area, not shown here PTC elements 11 (or functionally similar elements) are arranged. The left in the drawing, the end of the contact plate 12 has a contact tongue 13, which has a width a, which is smaller than the width b of the contact plate 12. Contact plate 12 and contact tongue 13 are integrally stamped from a metal sheet. The contact tongue 13 has a circular opening 14 in approximately central position.

Fig. 4a zeigt eine Einzelheit Y gemäß Fig. 4, d. h. im Wesentlichen die Kontaktzunge 13 mit kreisförmiger Öffnung 14. Erfindungsgemäß ist die Kontaktzunge 13 mit einer Beschichtung 15 überzogen, welche durch eine Kreuzschraffur dargestellt ist. Diese Beschichtung 15 ist zumindest auf der Vorder- und Rückseite der Kontaktzunge 13 angeordnet und besteht vorzugsweise aus Zinn. Eine solche Zinnschicht kann beispielsweise durch Tauchen der Kontaktzunge 13 in ein Zinnbad hergestellt werden. Zinn ist ein guter elektrischer Leiter und verbessert somit die elektrische Leitfähigkeit des aus einer Aluminiumlegierung oder aus Messing hergestellten Kontaktbleches 12. Die Form der Kontaktzunge 13 entspricht der eines genormten Flachsteckers, der in eine genormte Steckhülse gemäß DIN 46 247 gesteckt wird. Auf die verzinnten Kontaktzungen 13 werden also nicht dargestellte Steckhülsen gesteckt, die die Verbindung mit einer nicht dargestellten Stromquelle herstellen. Damit ist eine Flachsteckerverbindung mit großer Kontaktsicherheit und einem geringen Übergangswiderstand hergestellt. Alternativ könnte die Verzinnung der Kontaktzungen 13 auch durch eine Beschichtung mit Kupfer oder Silber erfolgen, wodurch ein noch geringerer Übergangswiderstand und damit ein noch geringerer Spannungsabfall zwischen Spannungsquelle und Kontaktblech 12 erzielbar wären. Die kreisförmige Öffnung 14 korrespondiert mit einer so genannten, hier nicht dargestellten Rastwarze der ebenfalls nicht dargestellten Steckhülse gemäß DIN 46 247. Durch die kreisförmige Öffnung 14 und die Rastwarze in der Stekkerhülse wird eine Rastverbindung zwischen der Kontaktzunge 13 und der nicht dargestellten Steckhülse hergestellt. 4a shows a detail Y according to FIG. 4, ie substantially the contact tongue 13 with a circular opening 14. According to the invention, the contact tongue 13 is coated with a coating 15, which is represented by a cross-hatching. This coating 15 is arranged at least on the front and back of the contact tongue 13 and is preferably made of tin. Such a tin layer can be produced, for example, by immersing the contact tongue 13 in a tin bath. Tin is a good electrical conductor and thus improves the electrical conductivity of the contact plate 12 made of an aluminum alloy or of brass. The shape of the contact tongue 13 corresponds to that of a standardized flat plug which is plugged into a standardized plug-in sleeve according to DIN 46 247. On the tinned contact tongues 13 so not plugged sockets are inserted, which make the connection to a power source, not shown. This is a flat connector with great contact reliability and a low contact resistance is made. Alternatively, the tinning of the contact tongues 13 could also be effected by a coating with copper or silver, whereby an even lower contact resistance and thus an even lower voltage drop between the voltage source and contact plate 12 would be achieved. The circular opening 14 corresponds to a so-called, not shown here Rastarmze the likewise not shown receptacle according to DIN 46 247. Through the circular opening 14 and the locking lug in the Stekkerhülse a locking connection between the contact tongue 13 and the plug-in sleeve, not shown.
