Definitions
- Such heaters are known as so-called surface heaters for heating the usually formed by foam pad seat and backrest of vehicle seats, see for example the EP 1 348 316 B1 .
- the substrate is formed by a woven or non-woven, in particular a non-woven fabric, and the heating layer consists of an electrically conductive plastic, which is composed for example of rubber, tetrahydrofuran, graphite and polyurethane.
- the heating layer forms a planar electrical resistance, which is heated by the electrical current passing through it.
- a similar heater is used in the US 4,060,710 shown.
- a substrate an electrical energizable heating layer which is coated on the side facing away from the substrate side with a heat insulation.
- PU foams ie open-cell plastic foams are provided, which may be soft, resilient or rigid (column 7, lines 53 to 57).
- substrates inter alia, tissue (column 5, line 32) or hard coatings such as Resopal (column 6, line 32) can be used. In this way, different basic hard or soft heating elements can be produced without principled modification of the production process.
- the heat generated by the heating layer must first heat the substrate before heat can be dissipated to the environment.
- a substrate made of heat-insulating foam particle is provided.
- the invention makes use of the knowledge that extremely lightweight and mechanically stable elements can be produced with particle foams. Accordingly, heating elements with a flat substrate of particle foam and a heating layer arranged thereon have a low weight with good mechanical stability. Furthermore, it is advantageous that the particle foam is a poor conductor of heat and accordingly only comparatively little heat is transferred from the heating layer into the substrate. Thus, the heat accumulating in the heating layer can be transferred largely without losses and without delay to gas flowing over the heating layer. It is advantageous that the heating layer can be formed over a large area and, accordingly, can transfer heat to large amounts of gas or air even at low flow rate. In addition, with the heating device according to the invention an internally heatable insulation layer or a surface heating, eg in buildings, created.
- the heating device according to the invention that at least in the region of a heating zone a penetrated by a gas flow pipe section of heat insulating foam and within this pipe section at least one plate made of thermally insulating foam with a particle can be heated by the electric current heating layer.
- heating layers can be arranged on both sides of the plate.
- the sheets of particle foam with a one-sided heating layer only and, if appropriate, to produce from two such sheets a built double sheet with a heating layer on both sides.
- a plurality of such plates are preferably arranged parallel to each other with plane parallel to the flow direction of the gas or the air plane.
- the tube part can have a window, which can be produced, for example, from acrylic glass.
- a window which can be produced, for example, from acrylic glass.
- FIG. 1 has a heater 1, a jacket tube 2, which consists of a polystyrene or polypropylene particle foam.
- a jacket tube 2 which consists of a polystyrene or polypropylene particle foam.
- five heating elements 3 are arranged in the example shown, each consisting of a polypropylene particle foam plate (substrate), on which a layer of a mixed with carbon nanotubes plastic is arranged as an electrically conductive heating layer.
- These heating layers 4 are electrically connected at their spaced in the longitudinal direction of the jacket tube 2 edges with conductor tracks 5, which in turn are electrically connected to electrical lines 6 and thus to an electrical power source 7.
- This may be, for example, a low-voltage power source that can supply an operating voltage of, for example, 30 volts at currents up to 20 A.
- a low-voltage power source that can supply an operating voltage of, for example, 30 volts at currents up to 20 A.
- an inner tube fan 8 is arranged so that during fan operation, the jacket tube is penetrated by a corresponding air flow.
- the case between the heating elements 3 flowing Air is heated according to the temperature of the respective heating layer 4.
- FIG. 2 shown heater differs from the embodiment of the FIG. 1 essentially in that in the jacket tube 2 in the region of the heating elements 3, an acrylic view window 9 is arranged in order to monitor the operation of the heating elements can.
- sensors not shown, outside the acrylic window 9 may be arranged to detect the thermal radiation of the heating layers of the heating elements 3. This offers the possibility to control or regulate the energization of the heating layers 4 as a function of temperature, so that all the heating layers deliver the same or respectively desired heat contributions. In this way, an overload of individual heating layers can be avoided by excessive temperature increase.
- Fig. 2 to 6 show by way of example various applications of the invention.
- the Fig. 3 shows a surface heating designed as a heating plate, wherein a Banklack Mrs 12 is applied to a substrate 11 made of particle foam, which extends between electrodes 13, which are also arranged on the substrate, and is electrically connected to the electrodes 13.
- the electrodes 13 are then connected via only schematically indicated lines 14 electrically connected to a voltage source, not shown.
- the electrical voltage source is switched on, the heating lacquer layer 12 is penetrated by an electric current, whereby the heating lacquer layer heats up. Due to the poor thermal conductivity of the substrate 11, which consists of particle foam, only very small amounts of heat are introduced into the substrate 11, the majority of the heat generated is transferred to the environment on the free side of the Edellacktik 12.
- the Fig. 4 shows a functionally similar surface heating, which differs from the arrangement Fig. 3 essentially only differs in that the substrate 11 is formed on both sides with free-form surfaces. In principle, any surface structures or adaptation to existing surfaces are possible in this way.
- Fig. 5 shows by way of example a substrate 11 with mutually arranged Banklack Anlagenen 12, which are electrically connected in parallel in the illustrated example, but in principle it is also possible to energize each of the heating layers 12 separately electrically.
- Fig. 6 shows the possibility of a multi-zone surface heating.
- a further electrode 13 " is provided between the edge-side electrodes 13 'of the Schulack Anlagen 12, in which case between the electrode 13" and in the drawing upper electrode 13', a first electrical voltage can be applied and between the electrode 13 "and in the drawing lower electrode 13 'another electrical voltage (possibly also a vanishing voltage) can be provided., In this way 12 different heating temperatures can be achieved during the heating operation on the Schulack Mrs.
- Fig. 7 shows the possibility of a basically arbitrary component 14, which rests on the Schulack Mrs, possibly with the interposition of an electrically insulating film, to heat by contact heating.
- the component 14 may be completely enveloped with particle foam.
- the component 14 may be arranged on several sides in contact with a Schulack Mrs 12.
- Fig. 8 again shows the possibility to heat a gas or air stream 10.
- the air flow 10 also flows over one side of the heating layer 12 arranged on a substrate 11 made of particle foam. On the other side, the air flow 10 is protected from heat loss by a heat insulation made of particle foam.
- Fig. 9 shows the example of a surface heating, which consists essentially of the substrate 11 and the heating lacquer layer 12 disposed thereon, which in turn can be electrically connected to a current source via electrodes 13.
- a seal 15 for example, made of a transparent acrylic material applied.
Description
Derartige Heizvorrichtungen sind als sogenannte Flächenheizungen zur Erwärmung der in der Regel durch Schaumstoffpolster gebildeten Sitzfläche und Rückenlehne von Fahrzeugsitzen bekannt, vergleiche beispielsweise die
Eine ähnliche Heizeinrichtung wird in der
Bei diesen bekannten Heizvorrichtungen muss also die von der Heizschicht erzeugte Wärme zunächst das Substrat aufheizen, bevor Wärme an die Umgebung abgeführt werden kann.In these known heating devices, therefore, the heat generated by the heating layer must first heat the substrate before heat can be dissipated to the environment.
Deshalb sind die bekannten flächigen Heizvorrichtungen für viele Anwendungen, insbesondere zur Erwärmung von Luft- oder Gasströmungen, ungeeignet.
Hier setzt die Erfindung an. Dabei ist es Aufgabe der Erfindung, eine einfach herstellbare Heizvorrichtung zur Erwärmung großer Flächen sowie von Luft- und Gasströmungen zu schaffen.Therefore, the known planar heating devices for many applications, in particular for heating air or gas flows, unsuitable.
This is where the invention starts. It is an object of the invention to provide an easy to manufacture heater for heating large areas and of air and gas flows.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst, wobei ein Substrat aus wärmeisolierendem Partikelschaumstoff vorgesehen ist. Die Erfindung nutzt die Erkenntnis, dass sich mit Partikelschaumstoffen äußerst leichte und mechanisch stabile Elemente herstellen lassen. Dementsprechend besitzen Heizelemente mit einem flächigen Substrat aus Partikelschaumstoff und einer darauf angeordneten Heizschicht ein geringes Gewicht bei guter mechanischer Stabilität. Des Weiteren ist vorteilhaft, dass der Partikelschaumstoff einen schlechten Wärmeleiter darstellt und dementsprechend von der Heizschicht nur vergleichsweise wenig Wärme in das Substrat übertragen wird. Somit kann die in der Heizschicht anfallende Wärme weitgehend ohne Verluste und ohne Verzögerung auf über die Heizschicht strömendes Gas übertragen werden. Dabei ist vorteilhaft, dass die Heizschicht großflächig ausgebildet sein kann und dementsprechend Wärme auf große Gas- bzw. Luftmengen auch bei geringer Strömungsgeschwindigkeit übertragen kann. Außerdem kann mit der erfindungsgemäßen Heizvorrichtung eine innenseitig beheizbare Isolationsschicht bzw. eine Flächenheizung, z.B. in Gebäuden, erstellt werden.This object is achieved by the characterizing features of
Gemäß einer besonders bevorzugten Ausführungsform kann bei der erfindungsgemäßen Heizvorrichtung vorgesehen sein, dass zumindest im Bereich einer Heizzone ein von einem Gasstrom durchsetzter Rohrabschnitt aus wärmeisolierendem Partikelschaum und innerhalb dieses Rohrabschnittes mindestens eine Platte aus wärmeisolierendem Partikelschaum mit einer durch die elektrische Bestromung erhitzbaren Heizschicht angeordnet ist.According to a particularly preferred embodiment, it can be provided in the heating device according to the invention that at least in the region of a heating zone a penetrated by a gas flow pipe section of heat insulating foam and within this pipe section at least one plate made of thermally insulating foam with a particle can be heated by the electric current heating layer.
Grundsätzlich können Heizschichten beidseitig der Platte angeordnet sein.In principle, heating layers can be arranged on both sides of the plate.
Herstellungsmäßig kann es jedoch vorteilhaft sein, die Platten aus Partikelschaum lediglich mit einseitiger Heizschicht zu versehen und gegebenenfalls aus zwei derartigen Platten eine gebaute Doppelplatte mit beidseitiger Heizschicht herzustellen. Innerhalb des Rohrabschnittes sind vorzugsweise mehrere derartige Platten mit zur Strömungsrichtung des Gases bzw. der Luft paralleler Plattenebene parallel zueinander angeordnet.In terms of production, however, it can be advantageous to provide the sheets of particle foam with a one-sided heating layer only and, if appropriate, to produce from two such sheets a built double sheet with a heating layer on both sides. Within the pipe section, a plurality of such plates are preferably arranged parallel to each other with plane parallel to the flow direction of the gas or the air plane.
Im Bereich der die Heizschichten tragenden Platten kann das Rohrteil ein Fenster aufweisen, welches beispielsweise aus Acrylglas hergestellt sein kann. Dies bietet den Vorteil, dass der Betrieb der Heizschichten von außerhalb des Rohrabschnittes überwacht werden kann, beispielsweise mit auf Wärmestrahlung reagierenden Sensoren. Dies ist unter anderem auch deshalb vorteilhaft, weil die Heizschichten zweckmäßiger Weise elektrisch parallel geschaltet sein sollten, jedoch mit der Möglichkeit, die jeweilige elektrische Bestromung in Abhängigkeit von der Temperatur und/oder der die jeweilige Heizschicht durchsetzten elektrischen Ströme steuern bzw. regeln zu können. Ohne eine derartige Steuerung bzw. Regelung besteht grundsätzlich die Gefahr einer Überlastung einer einzelnen Heizschicht. Dies beruht darauf, dass der elektrische Widerstand der Kunststoffheizschichten stark temperaturabhängig ist, so dass ohne Steuerungs- und Regelungsmaßnahmen der Fall einer extrem unterschiedlichen elektrischen Belastung einzelner Heizschichten auftreten könnte.In the area of the plates carrying the heating layers, the tube part can have a window, which can be produced, for example, from acrylic glass. This offers the advantage that the operation of the heating layers from outside the pipe section can be monitored, for example with responsive to heat radiation sensors. This is advantageous, inter alia, because the heating layers should expediently be electrically connected in parallel, but with the possibility of being able to control or regulate the respective electrical current supply as a function of the temperature and / or the electrical currents passing through the respective heating layer. Without such a control or regulation is basically the risk of overloading a single heating layer. This is based on the fact that the electrical resistance of the Kunststoffheizschichten is highly temperature-dependent, so that could occur without control and regulatory measures, the case of extremely different electrical load of individual heating layers.
Im Übrigen wird hinsichtlich bevorzugter Merkmale der Erfindung auf die Ansprüche und die nachfolgende Erläuterung der Zeichnung verwiesen, anhand der besonders bevorzugte Ausführungsformen der Erfindung näher beschrieben werden.Incidentally, with regard to preferred features of the invention, reference is made to the claims and the following explanation of the drawing, are described in detail with reference to the particularly preferred embodiments of the invention.
