Die Erfindung betrifft eine Vorrichtung zur Luftvorwärmung für Kraftfahrzeuge mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen. Eine derartige Vorrichtung ist aus der

An den bekannten Vorrichtungen ist die Herstellung, die Montage und die Wartung sowie der Betrieb nachteilig. Durch Beschleunigungen der Kolben und durch Kurbelwellenbewegungen entstehen Schwingungen in der Luft, die zu Relativbewegungen im Heizer und somit zu Verschleißerscheinungen zwischen den sich bewegenden Teilen führen. Durch Verwendung von Keramiken zur Abstützung eines Heizbandes und Verwendung von Federn zur Abstützung der Keramiken entstehen Relativbewegungen zwischen den Einzelteilen. Diese Bewegungen führen im fortschreitenden Betrieb zu Verschleiß. Ein weiterer Nachteil bei den bekannten Vorrichtungen ist der geringe Wirkungsgrad.In the known devices manufacturing, assembly and maintenance and operation is disadvantageous. Accelerations of the pistons and crankshaft movements cause vibrations in the air which lead to relative movements in the heater and thus to signs of wear between the moving parts. By using ceramics to support a heating tape and using springs to support the ceramics, relative movements occur between the parts. These movements lead to wear during ongoing operation. Another disadvantage of the known devices is the low efficiency.
Es ist die Aufgabe der vorliegenden Erfindung, eine verbesserte Vorrichtung zur Luftvorwärmung für Kraftfahrzeuge zu schaffen, die leichter herzustellen, zu montieren und zu warten und verschleißarm zu betreiben ist, der Wärmeübergang des Heizelementes an die Luft soll verbessert und damit der Wirkungsgrad erhöht werden.It is the object of the present invention to provide an improved device for air preheating for motor vehicles, which is easier to manufacture, to assemble and to maintain and to operate with low wear, the heat transfer of the heating element to the air to be improved and thus the efficiency can be increased.
Diese Aufgabe wird dadurch gelöst, dass eine Vorrichtung zum Luftvorwärmen für Kraftfahrzeuge zum Einsatz kommt, die die Merkmale des Anspruchs 1 aufweisen.This object is achieved in that a device for air preheating for motor vehicles is used, which have the features of
Daran ist vorteilhaft, dass keine verschleißbehafteten Federelemente benötigt werden, keine Reibung und damit einhergehender Verschleiß zwischen einzelnen Bauteilen auftritt. Die Eigenresonanzfrequenz des Heizbandes kann durch Variation des Bogens bzw. Knicks in einen für die Anwendung unkritischen Bereich verlagert werden. Ein weiterer erfindungsgemäßer Vorteil besteht in der Bauteilvereinfachung bzw. Bauteilreduktion bezogen auf das Gesamtprodukt, z. B. indem der Heizleiter aus gestanztem oder geschnittenem Blech gefertigt wird. Die erfindungsgemäße Luftvorwärmung für Kraftfahrzeuge ermöglicht einfachere Montagemöglichkeiten. Ein anderer Vorteil der Erfindung besteht im besseren Wärmeübergang, z. B. durch bessere Verwirbelung des Mediums, im Vergleich zum Stand der Technik., das Medium kann z. B. auch senkrecht zum Heizleiter strömen.It is advantageous that no wear-prone spring elements are needed, no friction and concomitant wear between individual components occurs. The self-resonant frequency of the heating tape can be moved by varying the arc or buckling in a non-critical for the application area. Another inventive advantage consists in the component simplification or component reduction based on the total product, for. B. by the heating element is made of stamped or cut sheet metal. The air preheating invention for motor vehicles allows easier mounting options. Another advantage of the invention is the better heat transfer, z. B. by better turbulence of the medium, in comparison to the prior art., The medium can, for. B. also flow perpendicular to the heating element.
Löcher im Heizleiter führen nicht nur zu Zonen unterschiedlicher elektrischer Widerstände und somit unterschiedlicher Temperaturgradienten, sondern auch zur Verringerung des Druckverlustes im Strömungsquerschnitt. Durch die Variation der Steg- bzw. Bandbreiten, die direkten Einfluss auf den elektrischen Widerstand und somit auf den Grad der Erwärmung bei der Bestromung des Heizbandes haben, kann der Ort der größten Erwärmung optimal an die Strömungsverhältnisse angepasst werden, die Bandbreite kann sich kontinuierlich ändern. Eine Bogenform mit definiertem Radius des Heizleiters ermöglicht eine Längenänderung des Heizleiters durch Temperaturänderungen und schützt ihn so vor Beschädigung. Eine Variante stellt z. B. ein Knick mit definiertem Winkel als Wärmeausgleichsstelle dar, der Längenänderung des Heizleiters durch Temperaturänderungen auszugleichen hilft, und ihn so vor Beschädigung schützt. Seitlich angeordnete Laschen, die z. B. bei der Herstellung des Heizleiters durch Biegen erzeugt werden, dienen zur Oberflächenvergrößerung.Holes in the heating conductor lead not only to zones of different electrical resistances and thus different temperature gradients, but also to the reduction of the pressure loss in the flow cross-section. By varying the web or bandwidths, which have a direct influence on the electrical resistance and thus on the degree of heating during the energization of the heating tape, the location of the largest warming can be optimally adapted to the flow conditions, the bandwidth can change continuously , An arc shape with a defined radius of the heat conductor allows a change in length of the heat conductor due to temperature changes, thus protecting it from damage. A variant provides z. B. a kink with a defined angle as a heat balance point, which helps to compensate for changes in length of the heating element by temperature changes, and thus protects it from damage. Laterally arranged tabs z. B. are produced by bending in the manufacture of the heating element, serve to increase the surface area.
