Hierbei weist die elektrisch leitfähige Folie bevorzugt eine wellenförmige Gestalt auf, wobei die von der zu erwärmenden Luft durchströmbaren Kanäle durch die einzelnen Wellen gebildet sind. Die Wellenform kann sinusförmig ausgebildet sein oder beliebig gekrümmte Wellen, dreieck-, trapez- oder rechteckförmige Wellen aufweisen.According to the invention a heating device, in particular for a motor vehicle, provided, which is electrically heated, comprising a luftdurchströmbare Structure of at least one electrically conductive, air-impermeable Film which is electrically heated to heat air wherein the film is a plurality of the one to be heated Air flows through channels. Hereby points the electrically conductive film preferably has a wavy shape on, which can be flowed through by the air to be heated Channels are formed by the individual waves. The waveform may be formed sinusoidal or arbitrarily curved Shafts, triangular, trapezoidal or rectangular waves have.
Besonders bevorzugt ist zwischen zwei elektrisch leitfähigen Folien mindestens eine elektrisch isolierende Folie oder eine Klebefolie angeordnet. Diese ermöglicht eine wellpappenartige Struktur, welche auch bei dünnen Folien eine relativ große Stabilität ermöglicht. Die abwechselnde Anordnung von Wellen und im Wesentlichen ebenen Flächen ermöglicht trotz einer Mehrzahl von Folien einen ausreichend großen Strömungsquerschnitt in Verbindung mit einer ausreichenden Steifigkeit.Especially preferred is between two electrically conductive films at least one electrically insulating film or an adhesive film arranged. This allows a corrugated structure, Which is a relatively large even with thin films Stability allows. The alternate arrangement of waves and substantially flat surfaces despite a large number of films a sufficiently large Flow cross-section in conjunction with a sufficient Rigidity.
Die isolierende Folie oder Klebefolie ist bevorzugt ausschließlich im Bereich von Bergen oder Tälern der elektrisch leitfähigen Folie in Kontakt, wobei die Kontaktflächen möglichst gering gehalten sind.The insulating film or adhesive film is preferred exclusively in the range of mountains or valleys of electrically conductive Foil in contact with the contact surfaces as possible are kept low.
Die Struktur, die durch die Folie(n) gebildet ist, ist bevorzugt zumindest bereichsweise mittels Wickeln und/oder Zusammenlegen ausgebildet. Hierbei kann beispielsweise ein Paar, bestehend aus einer elektrisch leitfähigen Folie mit Wellenstruktur und einer doppelseitigen, flachen Klebefolie walzenartig aufgerollt sein. Alternativ können beispielsweise mehrere Gruppen von elektrisch leitenden Folien und Klebefolien zusammengelegt und anschließend gewickelt sein. Ebenfalls kann ein Paar, bestehend aus einer elektrisch leitfähigen Folie mit Wellenstruktur und einer doppelseitigen, flachen Klebefolie, mäanderartig zusammengelegt sein, wobei die Wellenstruktur in den Endbereichen etwas beeinträchtigt wird.The Structure formed by the film (s) is preferably at least partially formed by winding and / or folding. Here, for example, a pair consisting of an electric conductive film with wave structure and a double-sided, flat adhesive film rolled up like a roll. Alternatively you can For example, several groups of electrically conductive films and adhesive films folded and then wrapped. Also can be a pair consisting of an electrically conductive Corrugated film with a double-sided, flat adhesive film, meandered together, the wave structure is slightly affected in the end areas.
Die elektrisch leitfähige Folie ist vorzugsweise auf Carbonfaserbasis, auf Carbonfaserbasis, eingebettet in eine Polymermatrix, oder aus einem Kunststoff mit PTC-Effekt gebildet.The electrically conductive film is preferably carbon fiber based, Carbon fiber-based embedded in a polymer matrix, or off a plastic with PTC effect formed.
Die elektrisch isolierende Folie oder Klebefolie besteht vorzugsweise aus Polyamid oder Polyäthylen. Hierbei ist besonders bevorzugt mindestens eine einseitige, vorzugsweise eine zweiseitige Beschichtung mit einem Klebstoff vorgesehen. Als Klebstoff dient bevorzugt ein Klebstoff auf Acrylat-Basis.The electrically insulating film or adhesive film is preferably made of polyamide or polyethylene. This is particularly preferred at least one unilateral, preferably a two-sided coating provided with an adhesive. As the adhesive is preferably a Acrylate-based adhesive.
Durch das Vorsehen von isolierenden Folien zwischen den einzelnen elektrisch leitenden Folien kann ein Kurzschluss verhindert werden. Ferner lassen sich einzelne Heizzonen und/oder Heizstufen realisieren.By the provision of insulating films between the individual electrically conductive foils, a short circuit can be prevented. Further Individual heating zones and / or heating stages can be realized.
Die elektrisch leitfähige Folie ist vorzugsweise auf zwei einander gegenüberliegenden und voneinander um annähernd die Länge der Heizvorrichtung beabstandeten Seiten mit einer elektrischen Kontaktierung versehen, die in Längsrichtung der Folie verlaufend angeordnet ist. Als elektrische Kontaktierung dienen vorzugsweise Kupferstreifen oder Streifen aus einer Kupferlegierung. Die Streifen können seitlich jeweils miteinander verbunden sein, so dass eine sehr einfache Kontaktierung einer Mehrzahl von Streifen möglich ist.The electrically conductive foil is preferably on two each other opposite and from each other by approximately the length of the heater spaced sides with an electrical contact provided in the longitudinal direction the film is arranged to extend. As electrical contact are preferably copper strips or strips of a copper alloy. The strips can be connected to each other laterally so that a very simple contacting of a plurality of Strip is possible.
Die Heizvorrichtung ist vorzugsweise auf Betriebstemperaturen von 50° bis 150°C, insbesondere 70° bis 130°C, ausgelegt. Diese Temperaturen ermöglichen optimale Betriebsbedingungen für die Zuheizung und ermöglichen zudem eine Regeneration, insbesondere bei einer Zusatzfunktion als Filter, sofern vorgesehen.The Heating device is preferably at operating temperatures of 50 ° to 150 ° C, in particular 70 ° to 130 ° C, designed. These temperatures allow optimal operating conditions for the heating and also allow regeneration, in particular with an additional function as a filter, if provided.
Vorzugsweise weist die Heizvorrichtung eine Heizleistung von bis zu 0,8 W/cm2 auf. Diese maximale Heizleistung ermöglicht eine schnelle Erwärmung der dem Fahrzeuginnenraum zuzuführenden Luft auch bei sehr geringen Außentemperaturen, so dass schnell eine komfortable Innenraumtemperatur zur Verfügung steht, auch wenn der Motor gerade erst gestartet wurde und daher die normale Heizung noch nicht funktioniert oder die volle Heizleistung (noch) nicht zur Verfügung steht. Dennoch kann insbesondere bei der vorgeschlagenen Heizleistung der Stromverbrauch auf akzeptablen Werten verbleiben. Als Werte bieten sich jedoch gegebenenfalls auch Heizleistungen bis zu 0,6 W/cm2, 0,7 W/cm2, 0,9 W/cm2 und/oder 1,0 W/cm2 an.Preferably, the heater has a heating power of up to 0.8 W / cm 2 . This maximum heat output allows rapid warming of the air supplied to the vehicle interior, even at very low outside temperatures, so that a comfortable interior temperature is quickly available, even if the engine has just been started and therefore the normal heating is not working or the full heating power (still ) is not available. Nevertheless, the power consumption can remain at acceptable levels, in particular for the proposed heating power. However, heating values of up to 0.6 W / cm 2 , 0.7 W / cm 2 , 0.9 W / cm 2 and / or 1.0 W / cm 2 may also be used as values.
Um einen größtmöglichen Komfort zu bieten, erreicht die Heizvorrichtung vorzugsweise – ausgehend von einer Temperatur von 20°C – eine Temperatur von 90°C innerhalb von 7 s. Hier bieten sich gegebenenfalls auch Zeitdauern von 5 s, 6 s, 8 s und/oder 9 s an.Around to achieve the greatest possible comfort the heating device preferably - starting from a Temperature of 20 ° C - a temperature of 90 ° C within 7 s. Here, if necessary, also provide time periods of 5 s, 6 s, 8 s and / or 9 s.

Bevorzugt kann die Heizvorrichtung in der Nähe des Luftausströmers zum Fahrzeuginnenraum angeordnet sein.The Heating device is preferably in an air duct of a motor vehicle ventilation system arranged, in particular in the plane of its cross section. Prefers can the heater near the air vent be arranged to the vehicle interior.
