Abstract
Description
Die Erfindung betrifft eine Rohrheizung mit mindestens einem Heizelement zum Beheizen des durch ein Rohr strömenden Fluids.The invention relates to a pipe heater with at least one heating element for heating the through a pipe flowing Fluid.
Es besteht vorwiegend in der Automobil-Industrie das Problem des Mediumvereisens von Rohren oder rohränlichen Leitungen. Dies führt insbesondere zu einer Reduzierung des Mediumdurchsatzes oder aber auch zu einer mechanischen Beschädigung von stromabwärts liegenden Aggregaten (z.B. Turbolader).It mainly exists in the automotive industry the problem of medium icing of pipes or pipe-like Cables. this leads to in particular to reduce the medium throughput or mechanical damage from downstream horizontal units (e.g. turbocharger).
Eine bekannte Rohrheizung umfasst ein kunststoffumspritztes Kupferrohrstück, das über einen Heizdraht beheizt wird.A known pipe heater includes a plastic-encapsulated piece of copper pipe that heats with a heating wire becomes.
Der Erfindung liegt die Aufgabe zugrunde, eine Rohrheizung der eingangs genannten Art weiter zu verbessern.The invention has for its object a To further improve pipe heating of the type mentioned.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das bzw. jedes Heizelement aus Kunststoff-Widerstandsmaterial gebildet ist, an das eine elektrische Spannung angelegt wird, und im lichten Querschnitt des Rohrs angeordnet ist.This object is achieved according to the invention solved, that the or each heating element made of plastic resistance material is formed, to which an electrical voltage is applied, and is arranged in the clear cross section of the tube.
Die erfindungsgemäße Rohrheizung hat den Vorteil, dass das bzw. die Heizelemente Strömungshindernisse für das im Rohr strömende Fluid darstellen. Daher wird das Fluid durch den unmittelbaren Kontakt mit dem bzw. den Heizelementen schneller erwärmt, so dass darin eventuell vorhandene Eispartikel geschmolzen werden.The pipe heater according to the invention has the advantage that the heating element or the flow obstacles for the in Pouring pipe Represent fluid. Therefore, the fluid comes through direct contact warmed up faster with the heating element (s), so that possibly existing ice particles are melted.
Vorzugsweise ist das bzw. jedes Heizelement ring-, ringscheiben- oder scheibenförmig ausgebildet, wobei mehrere Heizelemente mit axialem Abstand zueinander im Rohr angeordnet sind.The or each heating element is preferably annular, annular disc or disc-shaped, with several Heating elements are arranged at an axial distance from one another in the tube.
Bei besonders bevorzugten Ausführungsformen der erfindungsgemäßen Rohrheizung sind in Strömungsrichtung des Fluids hintereinander eine Lochscheibe, eine Prallscheibe und eine Siebscheibe angeordnet, von denen mindestens eine als Heizelement ausgebildet ist. Durch diese Maßnahme wird das Fluid labyrinthartig an dem bzw. den Heizelementen vorbeigeleitet, wodurch die Heizoberfläche vergrößert und daher eine bessere Heizleistung bewirkt wird. Außerdem entsteht durch die labyrinthartige Führung eine Verwirbelung des Fluids, wodurch vorhandene Eispartikel verstärkt geschmolzen werden. Bevorzugt ist dabei der Durchmesser der Prallscheibe größer als der Lochdurchmesser der Lochscheibe und als der Siebdurchmesser der Siebscheibe.In particularly preferred embodiments the pipe heater according to the invention are in the direction of flow of the fluid one behind the other a perforated disc, a baffle plate and a screen disc is arranged, at least one of which is used as a heating element is trained. By this measure the fluid is passed like a labyrinth past the heating element (s), which increases the heating surface and therefore better heating performance is effected. Also created by the labyrinthine guide a swirling of the fluid, causing existing ice particles to melt more become. The diameter of the baffle plate is preferably greater than the hole diameter of the perforated disc and as the sieve diameter the sieve.
Bei bevorzugten Ausführungsformen der Erfindung sind elektrische Anschlusskontakte als Einlegeteile in das bzw. jedes Heizelement eingebettet. Durch diese Maßnahme ist ein optimaler elektrisch leitender Kontakt zwischen den Anschlusskontakten und dem bzw. jedem Heizelement gegeben.In preferred embodiments the invention are electrical connection contacts as inserts embedded in the or each heating element. By this measure is an optimal electrically conductive contact between the connection contacts and given the or each heating element.
Vorzugsweise sind mehrere Heizelemente mit axialem Abstand nebeneinander auf zwei als Kontaktstäbe ausgebildeten Anschlusskontakten angeordnet, wobei die Kontaktstäbe auch zwischen den Heizelementen mit dem Kunststoff-Widerstandsmaterial umspritzt sein können. In diesem Fall können alle Heizelemente als ein einstöckiges Spritzgussteil hergestellt werden.Preferably, several heating elements are included axial distance next to each other on two designed as contact rods Arranged contacts, the contact rods also can be encapsulated between the heating elements with the plastic resistance material. In in this case everyone can Heating elements as a one-story Injection molded part to be made.
Weitere Vorteile der Erfindung ergeben sich aus der Beschreibung und der Zeichnung. Ebenso können die vorstehend genannten und die noch weiter aufgeführten Merkmale erfindungsgemäß jeweils einzeln für sich oder zu mehreren in beliebigen Kombinationen Verwendung finden. Die gezeigten und beschriebenen Ausführungsformen sind nicht als abschließende Aufzählung zu verstehen, sondern haben vielmehr beispielhaften Charakter für die Schilderung der Erfindung.Further advantages of the invention result itself from the description and the drawing. Likewise, the the above-mentioned and the features listed further according to the invention individually for themselves or more than one can be used in any combination. The embodiments shown and described are not as final enumeration to understand, but rather have exemplary character for the description the invention.
