Description
Flächenheizelement Die Erfindung befaßt sich mit einem Flächenheizelement, bestehend aus zwei elektrischen Strom führenden Leitern und einer dazwischen liegenden schwach leitfähigen Kunststoffschicht. Surface heating element The invention relates to a surface heating element, consisting of two conductors carrying electrical current and one in between weakly conductive plastic layer.
Für die Beheizung von Innenräumen und Freiflächen sind schon eine Anzahl ortsfester Flächenheizsysteme bekannt geworden, die zur Umwandlung der zugeführten elektrischen Energie in Wärme mäanderförmig ausgelegte, zu Matten verbundene Widerstandsdrähte mit temperaturbeständiger Isolierung aus Gummi oder Kunststoff verwenden.For the heating of interiors and open spaces there are already one Number of stationary surface heating systems have become known that are used to convert the supplied electrical energy in heat, meandering laid out resistance wires connected to form mats Use with temperature-resistant insulation made of rubber or plastic.
Es ist auch schon bekannt, derartige Heizleitungen in Schaumstoff einzubetten, wobei zwischen den Heizleitungen temperaturausgleichende Folien angeordnet sind.It is also already known to use foam heating cables of this type to be embedded, with temperature-compensating foils arranged between the heating cables are.
Des weiteren sind Gewebe aus leitfähig gemachten Textil-oder Glasfasern für Heizzwecke bekannt geworden, welche die elektrische Leitfähigkeit von dünnen Kohlenstoff- oder Graphitschichten für die Erwärmung ausnutzen sowie Folien aus leitfähig gemachten Kunststoff- und Gummimischungen wie Polyäthylen, Silikonegummi etc. Alle diese Flächenheizelemente haben den Nachteil, daß entweder die Temperaturverteilung ungleichmäßig ist - hohe Temperaturen in Heizleiternähe, niedrige Temperaturen in den Zwischenräumen - oder die Herstellung einen beträchtlichen Aufwand verlangt.Furthermore, fabrics are made of textile or glass fibers that have been rendered conductive become known for heating purposes, which the electrical conductivity of thin Use carbon or graphite layers for heating, as well as foils the end plastic and rubber compounds made conductive such as polyethylene, silicone rubber etc. All these surface heating elements have the disadvantage that either the temperature distribution is uneven - high temperatures in the vicinity of the heating conductor, low temperatures in the gaps - or the production requires considerable effort.
Die Erfindung vermeidet diese Nachteile. Gemäß der Erfindung sind die stromzuführenden Leiter flächenmäßig ausgebildet und parallel zueinander angeordnet, und der Raum zwischen den stromzuführenden Leitern ist mit einer schwach leitfähigen Kunststoffschicht ausgefüllt. Dadurch wird eine gleichmäßige Wärmeverteilung über die gesamte beheizte Fläche erreicht.The invention avoids these disadvantages. According to the invention are the current-carrying conductors are designed in terms of area and are arranged parallel to one another, and the space between the current-carrying conductors is weakly conductive Plastic layer filled. This will ensure even heat distribution over reaches the entire heated area.
Die flächenmäßig ausgebildeten stromzuführenden Leiter werden vorteilhaft aus einer Metallfolie, vorzugsweise aus Kupfer, hergestellt. Es können aber auch Folien aus Aluminium oder einer gut leitenden, leicht schmelzenden Legierung verwendet werden. Zweckmäßig ist es, dem Raum zugewandte Leiter aus einer Metallfolie zu erden, wodurch eine Berührung von spannungsführenden Teilen des Flächenheizelements in hohem Maße vermieden wird. Vorteilhaft ist es, wenn durch eine geeignete Ausbildung der spannungsführenden, nicht geerdeten Folie, z.B. aus schnell schmelzenden Legierungen oder auch Aluminium, beim Eintreten eines Kurzschlusses zwischen beiden Folien ein Wegschmelzen bzw. Wegbrennen der spannungsführenden Folie in der Umgebung der Kurzschlußstelle erreicht wird. Man kann aber auch die spannungsführende Folie etwas dünner ausgestalten als die geerdete Folie. Hierdurch ist es möglich, an jeder beliebigen Stelle Nägel in die Wand zu schlagen, zwecks Aufhängung eines Bildes etc., ohne daß das Flächenheizelement unbrauchbar wird und der Nagel Spannung führt. Die dem Raum zugewandte Seite der Metallfolie kann zur weiteren Sicherheit noch mit einer elektrisch isolierenden Schicht versehen werden. Damit die Wärme nicht in die Wand, an der das Heizelement befestigt ist, abwandert, ist die dem Raum abgewandte Fläche des Heizelementes mit Vorteil mit einer wärmedämmenden elektrisch isolierenden Schicht versehen.The areally designed current-supplying conductors are advantageous made of a metal foil, preferably of copper. But it can also Foils made of aluminum or a highly conductive, easily melting alloy are used will. It is advisable to ground conductors made of metal foil facing the room, whereby a contact of live parts of the surface heating element in is avoided to a large extent. It is advantageous if through a suitable training the live, ungrounded foil, e.g. made of rapidly melting alloys or aluminum, if a short circuit occurs between the two foils Melting away or burning away of the voltage-carrying film in the vicinity of the short-circuit point is achieved. But you can also make the live film a little thinner than the grounded foil. This makes it possible to use nails at any point in the Hitting the wall to hang a picture, etc., without that the surface heating element becomes unusable and the nail is under tension. The dem Space facing side of the metal foil can for further security still with a electrically insulating layer are provided. So that the heat does not get into the wall, to which the heating element is attached migrates, is the area facing away from the room of the heating element advantageously with a heat-insulating, electrically insulating layer Mistake.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.
Das Flächenheizelement, das im Ausführungsbeispiel als Wand heizelement dargestellt aber auch als Fußbodenheizung - in Estrich eingegossen - verwendet werden kann, besteht im wesentlichen aus der spannungsführenden, gut leitenden Folie 1, der gut leitenden, geerdeten Folie 2 und der zwischen beiden angeordneten schwach leitfähigen Kunststoffschicht 3.The surface heating element, the heating element in the embodiment as a wall shown but can also be used as underfloor heating - poured into the screed can, consists essentially of the voltage-carrying, highly conductive foil 1, the highly conductive, earthed film 2 and the weakly arranged between the two conductive plastic layer 3.
Während des Betriebes fließt der Strom von der Folie 1 durch die Kunststoffschicht 3 zur Folie 2 und erwärmt die Kunststoffschicht 3 infolge ihres großen Widerstandes. Als Material für die Kunststoffschicht eignet sich sowohl schwach leitende thermoplastische als auch duroplastische Kunststoffe; wichtig ist nur, daß sie in der Lage sind, die anfallende Wärmemenge nach außen hin abzuleiten. Zwischen der Wand 4 und der spannungsführenden Folie 1 ist eine Schicht 5 aus einem wärmedänenden isolierenden Material angeordnet. Diese Schicht 5 verhindert das Abwandern der Wärme in das Innere der Wand.During operation, the current flows from the film 1 through the plastic layer 3 to the film 2 and heats the plastic layer 3 due to its great resistance. Both weakly conductive thermoplastic materials are suitable as the material for the plastic layer as well as thermosetting plastics; it is only important that they are able to to dissipate the resulting amount of heat to the outside. Between the wall 4 and the voltage-carrying film 1 is a layer 5 of a heat-insulating insulating Material arranged. This layer 5 prevents the heat from migrating into the interior the wall.
Mit Hilfe eines Klebers 6 wird das Heizelement an der Wand befestigt. Die geerdete Folie 2 ist mit einer elektrisch isolierenden Schicht 7 bedeckt. Der elektrische Anschluß erfolgt über eine der Anschlußleisten 9 und 10, die von Klemmleisten 8 und 8a gehalten werden. Die Schraube 11 dient zur Befestigung der Klemmleiste an der Wand 4. Hit Hilfe der Schraube 12 und des Abstandshalterstückes 13 werden die'Anschlußleisten 9 und 10 gegen die Folien 1 und 2 gepreßt, so daß eine gute elektrische Verbindung erreicht wird.With the help of an adhesive 6, the heating element is attached to the wall. The grounded film 2 is covered with an electrically insulating layer 7. Of the electrical connection is made via one of the connection strips 9 and 10, the terminal strips 8 and 8a are held. The screw 11 is used to attach the terminal strip on the wall 4. Hit the help of the screw 12 and the spacer piece 13 will be die'Anschlussträger 9 and 10 pressed against the foils 1 and 2, so that a good electrical connection is achieved.
