Description

Die Erfindung betrifft einen elektrischen Flachheizkörper mit mindestens zwei Heizplatten, die durch Rohrstücke miteinander verbunden sind und mindestens eine Heizeinrichtung vorgesehen ist, welche von einem Heizmedium umgeben ist und die zwischen den Heizplatten angeordnet ist und durch Rohrabschnitte mit den Heizplatten verbunden ist, die den Ein- bzw. Auslauf in den Heizplatten für das Heizmedium umfassen.The invention relates to a flat electric radiator with at least two heating plates, which are connected by pipe pieces and at least one heating device is provided, which is surrounded by a heating medium and which is arranged between the heating plates and is connected by pipe sections with the heating plates, the Ein or outlet in the heating plates for the heating medium.

Elektrische Flachheizkörper sind bspw. aus der FR 2 865 527 A1 und der DE 20 2004 004 892 U1 bekannt und zeigen die Merkmale des Oberbegriffs von Anspruch 1. Sie weisen Heizplatten auf, die mit einem Heizmedium gefüllt sind. Die Erwärmung des Heizmediums erfolgt über die Heizeinrichtung, bei der es sich in der Regel um einen Heizstab handelt, der mit einer Schalteinrichtung und einem Thermoelement versehen ist. Zudem ist ein Regler vorgesehen, an dem die gewünschte Temperatur einstellbar ist.Electric flat radiators are, for example, from the FR 2 865 527 A1 and the DE 20 2004 004 892 U1 known and show the features of the preamble of claim 1. They have hot plates, which are filled with a heating medium. The heating of the heating medium via the heating device, which is usually a heating element, which is provided with a switching device and a thermocouple. In addition, a controller is provided on which the desired temperature is adjustable.

Die Heizeinrichtung ist bei mehrlagigen Flachheizkörpern am tiefsten Punkt des Heizkörpers zwischen den Heizplatten angeordnet. Das Heizmedium umgibt die Heizeinrichtung und erwärmt dieses, wodurch wiederum die Heizplatten erwärmt werden. Da elektrische Flachheizkörper anders als übliche Warmwasser-Heizkörper, die an das Rohrleitungssystem eines Gebäudes angeschlossen sind, über keine Zirkulation des Heizmediums verfügen, das Heizmedium vielmehr in dem Heizkörper "steht", dauert die Ausbreitung der Wärme im Heizmedium und damit die Erwärmung des gesamten Heizkörpers sehr lange. Zudem ergeben sich daraus große Temperaturunterschiede innerhalb der einzelnen Platten.The heater is arranged at multi-layer flat radiators at the lowest point of the radiator between the heating plates. The heating medium surrounds the Heating and heating this, which in turn the heating plates are heated. Since electrical panel radiators unlike conventional hot water radiators, which are connected to the piping system of a building, have no circulation of the heating medium, the heating medium rather "stands" in the radiator, the propagation of heat in the heating medium and thus the heating of the entire radiator very long. In addition, this results in large temperature differences within the individual plates.

Darüber hinaus führt die fehlende Zirkulation des Wassers dazu, dass das Wasser in unmittelbarer Nachbarschaft zum Heizstab aufgrund der schlechten Wärmeabfuhr sehr warm ist. Diese Wärme hat ein häufiges An- und Abschalten des Heizstabs zur Folge, wodurch die Lebensdauer sowohl des Heizstabs als auch der Schalteinrichtung erheblich reduziert ist.In addition, the lack of circulation of water causes the water in the immediate vicinity of the heating element is very warm due to the poor heat dissipation. This heat leads to frequent switching on and off of the heating rod, whereby the life of both the heating element and the switching device is significantly reduced.

Außerdem ist es bei Flachheizkörpern wünschenswert, eine Platte als Vorlauf und eine Platte als Rücklauf auszubilden. Diese Art der Ausbildung weist eine Reihe von Vorteilen auf. Ein ganz wesentlicher Vorteil besteht in einer besseren Wärmeausbreitung des gesamten Flachheizkörpers, wenn die als Vorlauf dienende Platte, die als wärmere Platte gilt, auf der dem jeweiligen Raum zugewandten Seite vorgesehen ist. Zudem bietet die definierte Ausbildung einer Vorlauf- und einer Rücklaufplatte den Vorteil, auch Anforderungen in Schulen, Kindergärten und dergleichen Rechnung zu tragen, bei denen es gewünscht ist, die wärmere Heizplatte auf der dem jeweiligen Raum abgewandten Seite anzuordnen, um die Verbrennungsgefahr zu verringern. Bei elektrischen Flachheizkörpern ist diese Definition von Vor- und Rücklaufplatte auf Grund der nicht gegebenen Zirkulation des Heizmediums nicht realisierbar, weshalb eine im Wesentlichen gleichmäßige Heizverteilung auf beide Heizplatten erfolgt. Dadurch ist die Wärmeleistung reduziert.In addition, it is desirable in panel heaters to form a plate as a feed and a plate as a return. This type of training has a number of advantages. A very significant advantage is better heat dissipation of the entire flat radiator, when the serving as a forward plate, which is considered a warmer plate, is provided on the side facing the respective space. In addition, the defined formation of a flow and a return plate has the advantage to take into account requirements in schools, kindergartens and the like, in which it is desired to arrange the warmer plate on the side facing away from the respective space to reduce the risk of burns. In electric panel radiators this definition of flow and return plate is not feasible due to the non-specified circulation of the heating medium, which is why a substantially uniform heating distribution takes place on both heating plates. As a result, the heat output is reduced.

Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zugrunde, einen elektrischen Flachheizkörper zu schaffen, bei dem eine Platte als Vorlauf und eine Platte als Rücklauf dient und eine Zirkulation des Heizmediums ermöglicht. Gemäß der Erfindung wird diese Aufgabe durch die Merkmale im kennzeichnenden Teil von Anspruch 1 gelöst.The invention aims to remedy this situation. The invention has for its object to provide a flat electrical radiator, in which a plate serves as a flow and a plate as a return and allows circulation of the heating medium. According to the invention, this object is solved by the features in the characterizing part of claim 1.

Mit der Erfindung ist ein elektrischer Flachheizkörper geschaffen, der eine bessere Wärmeverteilung ermöglicht. Durch die unterschiedliche Höhe des Auslauf aus der einen Platte in Richtung der Heizeinrichtung im Verhältnis zum Auslauf der anderen Heizplatte nach der Heizeinrichtung ist eine definierte Strömungsrichtung des erwärmten Heizmediums hervorgerufen, die in der einen Heizplatte eine Vorlauffunktion und in der anderen Heizplatte eine Rücklauffunktion hervorruft. Dadurch ist eine bessere, insbesondere gleichmäßigere Wärmeverteilung in dem Flachheizkörper hervorgerufen, was einen höheren Heizkomfort zur Folge hat. Darüber hinaus ist ein Temperaturstau in unmittelbarer Nähe des Heizstabs aufgrund der erzielten Zirkulation des Wassers verhindert, wodurch die Anzahl der An- und Abschaltungen des Heizstabs verringert ist, was die Lebensdauer des Heizstabs sowie der Schalteinrichtung erhöht. Die Stützeinlagen ermöglichen dabei eine einfache und zugleich stabile Anbindung der Rohrabschnitte an die Heizplatten. Durch die radiale Ausrichtung ist eine Erhöhung des Durchflusses ermöglicht, was die Heizleistung des Flachheizkörpers verbessert.With the invention, an electric flat radiator is created, which allows a better heat distribution. Due to the different height of the outlet from the one plate in the direction of the heater in relation to the outlet of the other heating plate after the heater, a defined flow direction of the heated heating medium is caused, which causes a flow function in one heating plate and a return function in the other heating plate. As a result, a better, in particular more uniform heat distribution is caused in the flat radiator, which has a higher heating comfort result. In addition, a temperature congestion in the immediate vicinity of the heating element is prevented due to the circulation of the water obtained, whereby the number of starts and stops of the heating element is reduced, which increases the life of the heating element and the switching device. The support inserts allow a simple and stable connection of the pipe sections to the heating plates. Due to the radial alignment, an increase in the flow is possible, which improves the heating power of the flat radiator.

In anderer Weiterbildung der Erfindung sind die Bohrung höchstens in einem Winkel von 90° zu einander angeordnet. Hiermit ist gewährleistet, dass das Heizmedium in die vorgegebene Richtung aus der Stutzeinlage austritt und daher trotz der Anordnung mehrerer Bohrungen die vorgesehene Durchströmrichtung eingehalten ist.In another embodiment of the invention, the bore are arranged at most at an angle of 90 ° to each other. This ensures that the heating medium exits in the predetermined direction of the support insert and therefore the intended flow direction is maintained despite the arrangement of several holes.

Der als Ausführungsbeispiel gewählte Flachheizkörper weist zwei Heizplatten 1, 2 auf. Die vordere Heizplatte 1 ist an ihrem dem Boden abgewandten Ende über Rohrstücke 3 mit der hinteren Heizplatte 2 verschweißt. Zwischen den Heizplatten 1 und 2 ist eine Heizeinrichtung 4 vorgesehen, die durch Rohrabschnitte 5 mit den Heizplatten 1 und 2 verbunden ist.The flat radiator chosen as an exemplary embodiment has two heating plates 1, 2. The front heating plate 1 is welded at its end facing away from the bottom pipe sections 3 with the rear heating plate 2. Between the heating plates 1 and 2, a heater 4 is provided, which is connected by pipe sections 5 with the heating plates 1 and 2.

Die Heizeinrichtung 4 besteht aus einem Vierkantrohr 41, das von einem Heizstab 42 durchsetzt ist. Das Vierkantrohr 41 verfügt über einen Anschluss 43, an dem ein nicht dargestelltes Thermoelement bzw. eine Schalteinrichtung anbringbar sind. Diese sind über eine Leitung mit einem Stecker versehen, der zum Betrieb des Flachheizkörpers in eine Steckdose einsteckbar ist.The heating device 4 consists of a square tube 41, which is penetrated by a heating element 42. The square tube 41 has a connection 43, to which a thermocouple, not shown, or a switching device can be attached. These are provided via a line with a plug that can be plugged into a socket to operate the flat radiator.

Das Vierkantrohr 41 ist mit Bohrungen 44 versehen, an denen die Rohrabschnitte 5 angeordnet sind. Durch die Bohrungen 44 tritt das Heizmedium in das Vierkantrohr 41 ein bzw. aus. In funktionsbereitem Zustand des elektrischen Flachheizkörpers ist das Vierkantrohr 41 ebenso wie die Heizplatten 1 und 2 einschließlich der Rohrstücke 3 und der Rohrabschnitte 5 vollständig mit dem jeweiligen Heizmedium gefüllt.The square tube 41 is provided with holes 44 on which the pipe sections 5 are arranged. Through the holes 44, the heating medium enters the square tube 41 on or off. In functional ready state of the electrical panel heater, the square tube 41 as well as the heating plates 1 and 2 including the pipe sections 3 and the pipe sections 5 is completely filled with the respective heating medium.

Auf der dem Vierkantrohr 41 abgewandten Seite sind die Rohrabschnitte 5 an den Heizplatten 1 und 2 angeordnet. Hierzu sind in den Heizplatten 1 und 2 Löcher 11, 21 vorgesehen, durch die der Ein- bzw. Auslauf des Heizmediums in den Heizplatten 1, 2 erfolgen kann. Im Bereich der Löcher 11, 21 sind in den Heizplatten 1 und 2 Stützeinlagen 6 angeordnet. Im Ausführungsbeispiel sind in jeder Heizplatte 1, 2 drei Stützeinlagen 6 vorgesehen.On the side facing away from the square tube 41 side, the pipe sections 5 are arranged on the heating plates 1 and 2. For this purpose, holes 11, 21 are provided in the heating plates 1 and 2, through which the inlet and outlet of the heating medium in the heating plates 1, 2 can be done. In the area of the holes 11, 21 1 and 2 support inserts 6 are arranged in the heating plates. In the exemplary embodiment, three support inserts 6 are provided in each heating plate 1, 2.

Die Stützeinlagen 6 sind nach Art eines Rings ausgebildet. Der Ring 61 umgibt eine Öffnung 62. In dem Ring 61 sind im Ausführungsbeispiel zwei radial ausgerichtete Bohrungen 63 vorgesehen, die eine Verbindung zwischen der Öffnung 62 und dem Umfang der Stützeinlage 6 hervorrufen. Die Bohrungen 63 in den Stützeinlagen 6 sind im Ausführungsbeispiel in einem Winkel von 40° zueinander angeordnet; im äußersten Fall weisen die Bohrungen höchstens einen Winkel von 90° zueinander auf.The support inserts 6 are formed in the manner of a ring. The ring 61 surrounds an opening 62. In the embodiment 61, two radially aligned holes 63 are provided in the ring 61, which cause a connection between the opening 62 and the circumference of the support insert 6. The holes 63 in the support inserts 6 are arranged in the embodiment at an angle of 40 ° to each other; in the extreme case, the holes at most at an angle of 90 ° to each other.

In der vorderen Heizplatte 1 sind die Bohrungen 63 in dem Ring 61 auf der dem Boden abgewandten Seite angeordnet. Sie sind somit nach oben ausgerichtet. In der hinteren Heizplatte 2 sind die Bohrungen 63 in dem Ring 63 auf der dem Boden zugewandten Seite angeordnet. Sie sind also nach unten ausgerichtet. Der Auslauf aus der hinteren Heizplatte 2 im Bereich der Heizeinrichtung 4 ist daher tiefer als der Einlauf in die vordere Heizplatte 1 angeordnet. Durch diese Anordnung bedingt hat das Heizmedium in der vorderen Heizplatte 1 lediglich die Möglichkeit, nach oben aus den Stützeinlagen 6 auszutreten. Da warmes Wasser aus den bekannten physikalischen Gründen nach oben steigt, führt diese Ausrichtung dazu, dass das von der Heizeinrichtung 4 aufgewärmte Heizmedium dazu neigt, durch die in der vorderen Heizplatte 1 vorgesehenen Stützeinlagen 6 auszutreten, da deren Bohrungen 63 nach oben ausgerichtet sind, also höher angeordnet ist, und somit dem natürlichen Drang des aufgeheizten Heizmediums entsprechen. Dies führt gleichzeitig zu einer schnelleren Ausbreitung der Wärme im Heizmedium, wodurch der Heizkörper insgesamt schneller erwärmt wird.In the front heating plate 1, the bores 63 are arranged in the ring 61 on the side facing away from the bottom. They are thus oriented upwards. In the rear heating plate 2, the bores 63 are arranged in the ring 63 on the side facing the bottom. So you are pointing down. The outlet from the rear heating plate 2 in the region of the heating device 4 is therefore arranged lower than the inlet into the front heating plate 1. Due to this arrangement, the heating medium in the front heating plate 1 only has the option to exit upwards from the support inserts 6. Since hot water rises for the known physical reasons, this orientation causes the heating medium warmed up by the heater 4 tends to leak through the support inserts 6 provided in the front heating plate 1, since their bores 63 are oriented upward, ie is higher, and thus correspond to the natural urge of the heated heating medium. This also leads to a faster propagation of heat in the heating medium, whereby the radiator is heated faster overall.

Die Ausrichtung der Bohrungen 63 der Stützeinlagen 6 in der hinteren Heizplatte 2 führt gleichermaßen dazu, dass das kühlere Heizmedium durch die nach unten ausgerichteten - tieferen - Bohrungen 63 in die Stützeinlagen 6 sowie die Rohrabschnitte 5 in Richtung der Heizeinrichtung 4 eintritt. In Folge dessen ist durch die gezielte und zugleich unterschiedliche Ausrichtung der Bohrungen 63 in den Stützeinlagen 6 eine Zirkulation des Heizmediums in den Heizplatten 1, 2 hervorgerufen, die zu einer zielgerichteten Durchströmung des Flachheizkörpers führt. Durch die Ausrichtung der Bohrungen 63 nach oben in der vorderen Heizplatte 1 wird diese zur Vorlaufplatte, wohingegen die hintere Heizplatte 2 als Rücklaufplatte fungiert. Dadurch ist ein Vor- bzw. Rücklauf in dem elektrischen Flachheizkörper hervorgerufen, obwohl dieser nicht von einem Heizmedium kontinuierlich durchströmt wird.The orientation of the bores 63 of the support inserts 6 in the rear heating plate 2 also leads to the cooler heating medium through the downwardly directed - deeper - bores 63 in the support inserts 6 and the pipe sections 5 in the direction of the heater 4 occurs. As a result, by the targeted and at the same time different orientation of the holes 63 in the support inserts 6, a circulation of the heating medium in the heating plates 1, 2 caused, which leads to a targeted flow through the panel radiator. By aligning the bores 63 up in the front heating plate 1, this is the feed plate, whereas the rear heating plate 2 acts as a return plate. As a result, a flow or return is caused in the electric flat radiator, although this is not continuously flowed through by a heating medium.

In Abwandlung des Ausführungsbeispiels besteht auch die Möglichkeit, lediglich die Öffnungen in den Heizplatten 1 und 2, an die die Rohrabschnitte 5 angeschlossen sind, unterschiedlich hoch anzuordnen. Auch hierdurch ist eine Zirkulation des Heizmediums hervorgerufen. Prinzipiell ist es zur Erzielung einer Zirkulation des Heizmediums bei Heizkörpern der hier betrachteten Art nur erforderlich, eine gedankliche schiefe Ebene zwischen Auslauf aus der hinteren Heizplatte 2 im Bereich der Heizeinrichtung 4 und Einlauf in die vordere Heizplatte 1 zu schaffen, wie dies anhand der mit "7" gekennzeichneten Linie in Figur 3 dargestellt ist. Durch den geschaffenen Höhenunterschied kann die Zirkulation des Heizmediums erzielt werden.In a modification of the embodiment, it is also possible, only the openings in the heating plates 1 and 2, to which the pipe sections 5 are connected, to arrange different heights. This also causes a circulation of the heating medium. In principle, in order to achieve a circulation of the heating medium in radiators of the type considered here, it is only necessary to create a mental inclined plane between the outlet from the rear heating plate 2 in the region of the heating device 4 and the inlet into the front heating plate 1, as described with reference to FIG. 7 "marked line in FIG. 3 is shown. The created height difference, the circulation of the heating medium can be achieved.
