Description
Technisches GebietTechnical area
Die Erfindung betrifft eine Heizvorrichtung für Fluide, insbesondere Kraftstoffe, Schmierstoffe und/oder Harnstofflösungen. Derlei Heizvorrichtungen werden in der Praxis eingesetzt, um eine mit niederen Umgebungs- oder Betriebstemperaturen einhergehende Viskositätszunahme, einem Ausflocken von Paraffinen bei Dieselkraftstoffen bzw. einem unerwünschten Gefrieren der Fluide entgegenzuwirken.The invention relates to a heating device for fluids, in particular fuels, lubricants and / or urea solutions. Such heaters are used in practice to counteract an associated with low ambient or operating temperatures viscosity increase, flocculation of paraffins in diesel fuels or undesirable freezing of the fluids.
Stand der TechnikState of the art
Die
Aus der
Aufgabe der Erfindung ist es demgegenüber, eine Heizvorrichtung anzugeben, die zwar konstruktiv einfach ausgebildet ist, aber dennoch eine wohldefinierte Heizleistung erbringt und weitestgehend inert gegen chemische und physikalische Einflüsse ist.The object of the invention is in contrast to provide a heater which, although structurally simple, yet provides a well-defined heating capacity and is largely inert to chemical and physical influences.
Offenbarung der ErfindungDisclosure of the invention
Diese Aufgabe wird durch eine Heizvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.This object is achieved by a heating device with the features of claim 1. The dependent claims indicate expedient developments.
Die Heizvorrichtung zeichnet sich durch den Einsatz einer flexibel verformbaren Heizfolie, wie diese am Markt vorkonfektioniert frei erhältlich sind, durch niedrige Herstellungskosten und ein hochflexibles Design aus. So kann die Heizvorrichtung insgesamt mit einer ebenen, einer gebogenen, ringförmigen, bananenförmigen oder auch welligen Formgebung realisiert werden und so an beliebige Einbauräume angepasst werden. Darüber hinaus erlaubt der Einsatz der standardisierten Heizfolien eine enge Tolerierung der Heizleistung der Heizvorrichtung.The heating device is characterized by the use of a flexibly deformable heating foil, as they are freely available on the market, due to low production costs and a highly flexible design. Thus, the heater can be realized with a total of a flat, a curved, annular, banana-shaped or wavy shape and be adapted to any installation space. In addition, the use of standardized heating films allows close tolerance of the heating power of the heater.
Dadurch, dass die Heizfolie zwischen den beiden flächigen Wärmeleitelementen angeordnet und mit diesen gemeinsam in der Kunststoffschicht vergossen ist, ergibt sich ein insgesamt formstabiler Sandwichaufbau der Heizvorrichtung in Form eines Flächenheizelements. Die beiden Wärmeleitelemente gewährleisten dabei eine gleichmäßigere Wärmeabgabe über die Oberfläche der Heizvorrichtung. Durch die Kunststoffschicht sowie die beiden Wärmeleitelemente kann die Heizfolie vor einer mechanischen Überbeanspruchung, beispielsweise durch einen Gefrierdruck des Fluids, zuverlässig geschützt werden. In gleicher Weise kann durch die Kunststoffschicht, d. h. die Kunststoffummantelung der Heizvorrichtung, ein Eindringen des Fluids selbst bei hohem Betriebsdrücken im Bereich der elektrischen Kontakte der Heizfolie zuverlässig unterbunden werden. Die stromführenden Heizelemente, insbesondere in Form von Widerstandsheizelementen, sind dadurch optimal vor chemischen und physikalischen Einflüssen des aufzuwärmenden Fluids geschützt. Die Kunststoffschicht kann unter fertigungstechnischen Gesichtspunkten vorteilhaft aus einem Thermoplasten bestehen.The fact that the heating foil is arranged between the two flat heat-conducting elements and is cast together with these in the plastic layer, results in a generally dimensionally stable sandwich construction of the heating device in the form of a surface heating element. The two heat-conducting elements ensure a more uniform heat dissipation over the surface of the heater. Due to the plastic layer and the two heat-conducting elements, the heating foil can be reliably protected against mechanical overuse, for example by a freeze pressure of the fluid. Similarly, the plastic layer, i. H. the plastic casing of the heating device, penetration of the fluid can be reliably prevented even at high operating pressures in the range of electrical contacts of the heating foil. The current-carrying heating elements, in particular in the form of resistance heating elements, are thus optimally protected against chemical and physical influences of the fluid to be heated. The plastic layer may advantageously consist of a thermoplastic under manufacturing aspects.
Nach einer bevorzugten Weiterbildung der Erfindung weist die Heizvorrichtung eine oder mehrere Durchströmöffnung(en) für das aufzuheizende Fluid auf. Eine solche Durchströmöffnung ermöglicht eine Durchströmung der Heizvorrichtung in einer zur Oberfläche des Flächenheizelements schräg verlaufenden Strömungsrichtung. Dadurch weist das Flächenheizelement ein nochmals breiteres Einsatzspektrum auf und kann beispielsweise bei einem Filterelement zum Filtern des Fluids eingesetzt werden.According to a preferred development of the invention, the heating device has one or more throughflow opening (s) for the fluid to be heated. Such a flow opening allows a flow through the heating device in a direction of flow obliquely to the surface of the surface heating element. As a result, the surface heating element has a wider range of uses and can be used, for example, in a filter element for filtering the fluid.
Die elektrischen Kontakte der Heizfolie können nach der Erfindung jeweils mit einem elektrischen Steckverbinder verbunden sein, der in der Kunststoffschicht teilweise eingebettet ist. Dadurch kann ein mechanisch stabiler Anschluss für ein Kupplungsteil eines elektrischen Anschlusskabels realisiert werden.The electrical contacts of the heating foil can each be connected according to the invention with an electrical connector which is partially embedded in the plastic layer. As a result, a mechanically stable connection for a coupling part of an electrical connection cable can be realized.
Besonders bevorzugt ist der Kunststoffschicht ein Verbindungsmittel für das vorgenannte Kupplungsteil des elektrischen Anschlusskabels angeformt. Das Verbindungsmittel kann in Form eines oder mehrerer Rastmittel zum Verrasten des Kupplungsteils ausgebildet sein. Das Verbindungsmittel ist bevorzugt integraler Bestandteil der Kunststoffschicht und kann gemeinsam mit dieser im Wege eines Spritzgussverfahrens auf kostengünstige Weise erzeugt werden.Particularly preferably, the plastic layer is formed a connecting means for the aforementioned coupling part of the electrical connection cable. The connecting means may be designed in the form of one or more latching means for latching the coupling part. The connecting means is preferably an integral part of the plastic layer and can together with this in the way an injection molding process can be produced in a cost effective manner.
Zur nochmals weiter verbesserten Abdichtung des Flächenheizelements im Bereich seiner elektrischen Kontakte hat es sich als vorteilhaft ergeben, wenn das Flächenheizelement ein Dichtungselement aufweist, mittels dessen das Kupplungsteil abdichtbar ist. Das Dichtungselement kann im konstruktiv einfachsten Fall als ein gummielastisch verformbarer O-Ring ausgeführt sein. Die Heizvorrichtung weist in diesem Fall vorteilhaft eine an der Kunststoffschicht angeformte Schulter und/oder eine Ringnut auf, an der das Dichtungselement dichtend abgestützt ist.For further improved sealing of the surface heating element in the region of its electrical contacts, it has proven to be advantageous if the surface heating element has a sealing element, by means of which the coupling part is sealable. The sealing element may be executed in the structurally simplest case as a rubber elastic deformable O-ring. In this case, the heating device advantageously has a shoulder integrally formed on the plastic layer and / or an annular groove on which the sealing element is sealingly supported.
Die beiden Wärmeleitelemente bestehen vorzugsweise aus demselben Material. Zwecks einer guten Wärmeleitfähigkeit können diese insbesondere aus Metall oder aus einer Metalllegierung bestehen. Besonders bevorzugt sind die Wärmeleitelemente als Bleche ausgebildet.The two heat-conducting elements are preferably made of the same material. For the purpose of good thermal conductivity, these may consist in particular of metal or of a metal alloy. Particularly preferably, the heat-conducting elements are formed as sheets.
Nach einer besonders bevorzugten Weiterbildung der Erfindung ist die Kunststoffschicht mit Befestigungsmitteln versehen, mittels derer die Heizvorrichtung an ihrer Einbauposition an einem Filterelement, einem Filtergehäuse oder auch innerhalb eines Fluidtanks, befestigbar ist. Die Befestigungsmittel sind der Kunststoffschicht unter fertigungstechnischen Aspekten vorteilhaft angeformt und dadurch als integraler Bestandteil der Heizvorrichtung ausgebildet. Die Befestigungsmittel können im einfachsten Fall zumindest teilweise als Rastzungen ausgebildet sein. Dadurch kann die Heizvorrichtung werkzeugfrei an ihrer Einbauposition, beispielsweise am Filterelement bzw. Filtergehäuse oder auch im Fluidtank eines Kraftfahrzeugs, befestigt werden.According to a particularly preferred embodiment of the invention, the plastic layer is provided with fastening means by means of which the heating device at its installation position on a filter element, a filter housing or even within a fluid tank, can be fastened. The fastening means are the plastic layer advantageously formed under manufacturing aspects and thereby formed as an integral part of the heater. The fastening means may be formed in the simplest case at least partially as locking tongues. As a result, the heater can be fastened without tools at its installation position, for example on the filter element or filter housing or in the fluid tank of a motor vehicle.
Zum Erzeugen der beiden Wärmeleitelemente kann/können in einen plattenförmigen Rohling eine oder mehrere Öffnungen eingebracht werden, wobei die Heizfolie mit einer oder mehreren dazu korrespondierenden Öffnungen versehen wird.To produce the two heat-conducting elements, one or more openings can be introduced into a plate-shaped blank, wherein the heating foil is provided with one or more openings corresponding thereto.
Zum Erzeugen der beiden Wärmeleitelemente können insbesondere zwei plattenförmige Rohlinge, etwa Blechstücke, in Form gebogen und ggf. mit einer oder mehreren Ausnehmungen zum Bilden der späteren Durchströmöffnung(en) des Flächenheizelements versehen werden.To produce the two heat-conducting elements, in particular two plate-shaped blanks, such as sheet metal pieces, may be bent into shape and possibly provided with one or more recesses for forming the later flow opening (s) of the surface heating element.
Die Erfindung wird nachstehend anhand von in der Zeichnung wiedergegebenen Ausführungsbeispielen erläutert. Die verschiedenen dort gezeigten Merkmale können je einzeln für sich oder zu mehreren in beliebigen Kombinationen bei Varianten der Erfindung verwirklicht sein.The invention will be explained below with reference to exemplary embodiments shown in the drawing.

Die erfindungsgemäße Heizvorrichtung kann aufgrund ihrer variabel ausgestaltbaren Formgebung bei einer Vielzahl von technischen Anwendungen eingesetzt werden, um ein Fluid aufzuwärmen bzw. aufzuheizen. So kann die Heizvorrichtung neben dem gezeigten Anbau an Filterelementen auch direkt in einem Filtergehäuse zur Aufnahme eines Filterelements, innerhalb von schlauch- oder rohrförmigen Fluidleitungen, in Vorratstanks und dergl. montiert werden. Aufgrund der mehrfach gekapselten Anordnung des Widerstandsheizelements kann die Heizvorrichtung dabei auch zum Erwärmen aggressiver Medien und bei Hochdruckanwendungen eingesetzt werden.The heating device according to the invention can be used in a variety of technical applications due to their variably ausgestaltetbaren shaping to heat or heat a fluid. Thus, in addition to the shown attachment to filter elements, the heating device can also be mounted directly in a filter housing for receiving a filter element, within tubular or tubular fluid lines, in storage tanks and the like. Due to the multiple encapsulated arrangement of the resistance heating element, the heater can also be used for heating aggressive media and high pressure applications.
