Description
Die Erfindung betrifft einen Heizkörper für Kraftfahrzeuge nach dem Oberbegriff von Anspruch 1.The invention relates to a radiator for motor vehicles according to the preamble of claim 1.
Die Beheizung des Fahrzeuginnenraums bei Kraftfahrzeugen erfolgt üblicherweise mittels des Kühlmittels des Antriebsaggregates, so dass die in der Brennkraftmaschine entstehende Wärme bedarfsweise an die in den Fahrzeuginnenraum strömende Luft abgegeben wird. Diese Wärme steht jedoch erst nach einer bestimmten Betriebsdauer zur Verfügung, so dass insbesondere in der kalten Jahreszeit das Wirksamwerden der Heizung als unzureichend empfunden wird. Auch durch die Entwicklung neuer, verbrauchsoptimierter Motoren, in denen weniger Wärmeenergie anfällt und über das Kühlmittel abgeführt wird, steht zur Fahrzeugheizung eine geringere Wärmeenergie zur Verfügung, die bei extrem niedrigen Außentemperaturen keineswegs zur Fahrzeugheizung ausreicht und die auch bei normalem Heizungsbedarf erst bei erheblicher zeitlicher Verzögerung zu behaglichen Innenraumtemperaturen führt. Gleiches gilt für die Beheizung von Elektro-Fahrzeugen.The vehicle interior in motor vehicles is usually heated by means of the coolant of the drive unit, so that the heat generated in the internal combustion engine is released, if necessary, to the air flowing into the vehicle interior. However, this heat is only available after a certain operating time, so that the effectiveness of the heating is perceived as insufficient, especially in the cold season. The development of new, consumption-optimized engines in which less heat energy is generated and dissipated via the coolant means that less heat energy is available for vehicle heating, which is in no way sufficient for vehicle heating at extremely low outside temperatures, and which, even with normal heating requirements, only takes a considerable time delay leads to comfortable interior temperatures. The same applies to the heating of electric vehicles.
Aus den vorstehenden Gründen wurden bereits Zusatzheizungen vorgeschlagen, die in den Luftführungskanal eingesetzt werden und die Wärme an die in den Fahrzeuginnenraum strömende Luft abgeben. Die Anordnung einer Zusatzheizung zwischen einem Wärmeübertrager einer Fahrzeugheizungsanlage und der Fahrzeugkabine ist beispielsweise in dem Aufsatz von Burk, Krauss, Löhle „Integrales Klimasystem für Elektroautomobile“, ATZ Automobiltechnische Zeitschrift, 11/1992, beschrieben.For the above reasons additional heaters have already been proposed, which are inserted into the air duct and give off the heat to the air flowing into the vehicle interior. The arrangement of an additional heater between a heat exchanger of a vehicle heating system and the vehicle cabin is described, for example, in the article by Burk, Krauss, Löhle "Integral Air Conditioning System for Electric Cars", ATZ Automobiltechnische Zeitschrift, 11/1992.
Aus der Druckschrift
Nachteilig an einem solchen bekannten Wärmeübertrager ist, dass zur Aufnahme der Heizelemente ein Gehäuse nötig ist, für das im Rippenrohrblock des Wärmeübertragers unter Zuhilfenahme einer Dummy-Platte in einem relativ aufwendigen Verfahren ein Aufnahmeraum geschaffen ist.A disadvantage of such a known heat exchanger is that a housing is required to accommodate the heating elements, for which a receiving space is created in the finned tube block of the heat exchanger with the aid of a dummy plate in a relatively complex process.
Des Weiteren ist eine elektrische Zusatzheizung für ein Kraftfahrzeug aus der Druckschrift

Die
Der Erfindung liegt die Aufgabe zugrunde, einen Heizkörper der eingangs genannten Art derart weiterzubilden, dass die Fertigung und die Montage der Heizelemente innerhalb des Heizkörpers vereinfacht ist und wirtschaftlicher gestaltet wird.The invention has for its object to develop a radiator of the type mentioned in such a way that the manufacture and assembly of the heating elements within the radiator is simplified and is made more economical.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.
Erfindungsgemäß ist vorgesehen, dass der Rippenrohrblock wenigstens ein Aufnahmeelement zur Aufnahme der Heizelemente aufweist, das mit dem Rippenrohrblock verlötbar ist. Durch ein solchermaßen in den Rippenrohrblock integriertes Aufnahmeelement, das mit dem Rippenrohrblock in einem Schuss verlötbar ist und damit Teil des Rippenrohrblocks ist, ist es ermöglicht, bei hinreichend großen Materialstärken des Aufnahmeelements auf eine Dummy-Platte zur Herstellung eines Hohlraumes zur Aufnahme der Heizelemente vollständig zu verzichten, oder aber bei geringeren Materialstärken des Aufnahmeelements eine vereinfachte Dummy-Platte zu verwenden. Dabei können die Aufnahmeelemente unmittelbar während der Kassettierung der Rohre und Rippen des Rippenrohrblocks in diesen eingebracht werden, in dem sie dann auch verbleiben und aus dem sie nicht mehr entfernt zu werden brauchen.According to the invention, it is provided that the finned tube block has at least one receiving element for receiving the heating elements, which can be soldered to the finned tube block. A receiving element integrated into the finned tube block in this way, which can be soldered to the finned tube block in one shot and is therefore part of the finned tube block, makes it possible, with sufficiently large material thicknesses of the receiving element, to place it on a dummy plate for producing a cavity for receiving the heating elements waive, or to use a simplified dummy plate with lower material thicknesses of the receiving element. The Receiving elements are inserted directly into the tubes and fins of the finned tube block in the cassette, in which they then remain and from which they no longer need to be removed.
In weiterer Ausgestaltung der Erfindung sind die Aufnahmeelemente als Flachrohre ausgebildet, deren erster Endbereich jeweils in oder an den Sammelkasten mündet und deren zweiter Endbereich zum Einbringen der Heizelemente offen ausgeführt ist, wobei der erste Endbereich gegenüber dem Sammelkasten fluiddicht verschlossen ist. Diese einseitig offen gestaltete Ausführung der Aufnahmeelemente in Form von Flachrohren, die einen quer zur Rohrlängsachse etwa rechteckigen Querschnitt aufweisen, ist dabei besonders für Wärmeübertrager mit lediglich einem Sammelkasten und in den Wärmeübertrager-Rohren erfolgender Umlenkung in der Tiefe geeignet, indem der dem Sammelkasten abgewandte zweite Endbereich zum Einbringen der Heizelemente offen ausgeführt ist. Der fluiddichte Verschluss des dem Sammelkasten zugewandten ersten Endbereichs kann dabei entweder durch eine endseitige Abdichtung des Flachrohres oder durch eine Abdichtung des Rohrbodens des Sammelkastens, beispielsweise durch das Weglassen von Durchzügen an dieser Stelle, erfolgen.In a further embodiment of the invention, the receptacle elements are designed as flat tubes, the first end area of which opens into or onto the collecting tank and the second end area of which is open for the introduction of the heating elements, the first end area being fluid-tightly sealed from the collecting tank. This open-sided design of the receiving elements in the form of flat tubes, which have an approximately rectangular cross section transverse to the longitudinal axis of the tube, is particularly suitable for heat exchangers with only one header box and deflection in the heat exchanger tubes in depth by the second facing away from the header box End area for introducing the heating elements is open. The fluid-tight closure of the first end region facing the collecting box can be achieved either by sealing the flat tube at the end or by sealing the tube bottom of the collecting box, for example by omitting passages at this point.
In weiterer Ausgestaltung der Erfindung sind die Aufnahmeelemente als Flachrohre ausgebildet, deren erster Endbereich jeweils in oder an den Sammelkasten mündet und gegenüber dem Sammelkasten fluiddicht verschlossen ist, und deren zweiter Endbereich geschlossen ausgeführt sein kann, wobei eine Stirnseite des Flachrohres zum Einbringen der Heizelemente wenigstens zum Teil offen ausgeführt ist. Diese gegenüber der o. g. Ausgestaltung alternative Flachrohrgeometrie ist dabei sowohl für Wärmeübertrager mit einem als auch mit zwei Sammelkästen geeignet, da die Flachrohre im Bereich von beiden Endbereichen geschlossen sind. Ein Einbringen der Heizelemente erfolgt stattdessen über eine wenigstens zum Teil offen ausgeführte Stirnseite, wobei es sich dabei vorzugsweise um die leeseitig gelegene Stirnseite des Flachrohres handelt. Damit weist das Flachrohr in diesem offen ausgeführten Bereich ein im Querschnitt etwa U-förmiges Profil auf.In a further embodiment of the invention, the receiving elements are designed as flat tubes, the first end area of which opens into or at the collecting tank and is fluid-tightly sealed with respect to the collecting tank, and the second end area of which can be made closed, with one end face of the flat tube for inserting the heating elements at least for Part is open. This compared to the above Design of alternative flat tube geometry is suitable both for heat exchangers with one and with two header boxes, since the flat tubes are closed in the region of both end regions. Instead, the heating elements are introduced via an at least partially open end, which is preferably the leeward end of the flat tube. The flat tube thus has a profile which is approximately U-shaped in cross section in this open area.
Erfindungsgemäß sind die Aufnahmeelemente jeweils zwischen zwei Wellrippen angeordnet. Dabei sind gegenüber einem nicht mit Aufnahmeelementen versehenen Wärmeübertrager jeweils zwei Wärmeübertrager-Rohre und eine Wellrippe ausgespart, deren Platz jeweils durch die Aufnahmeelemente eingenommen ist, so dass diese jeweils von zwei Wellrippen benachbart sind.According to the invention, the receiving elements are each arranged between two corrugated ribs. Compared to a heat exchanger not provided with receiving elements, two heat exchanger tubes and a corrugated fin are cut out, the space of which is occupied by the receiving elements, so that they are each adjacent to two corrugated fins.
Erfindungsgemäß ist vorgesehen, dass die Heizelemente durch wenigstens ein Isolationselement in Richtung der Rohr-Längsachse und Rohr-Querachse der Aufnahmeelemente fixiert gehalten sind, sowie in Richtung der Rohr-Hochachse einerseits an einer Flachseite der Aufnahmeelemente und andererseits an wenigstens einer elektrisch leitfähigen Kontaktplatte anliegen, wobei die Kontaktplatte durch Federelemente gegen die Heizelemente gehalten ist. Dabei nehmen die Kontaktplatten sowohl eine Verteilung der Halte- bzw. Anpresskräfte der Federelemente als auch einen Pol der elektrischen Anschlüsse der Heizelemente wahr.According to the invention, it is provided that the heating elements are held fixed by at least one insulation element in the direction of the tube longitudinal axis and tube transverse axis of the receiving elements, and in the direction of the tube vertical axis are on the one hand on a flat side of the receiving elements and on the other hand on at least one electrically conductive contact plate, wherein the contact plate is held against the heating elements by spring elements. The contact plates perceive both a distribution of the holding or pressing forces of the spring elements and a pole of the electrical connections of the heating elements.
In weiterer Ausgestaltung der Erfindung liegen Heizelemente an beiden Flachseiten der Aufnahmeelemente an, wobei die jeweiligen Kontaktplatten durch wenigstens ein Federelement voneinander beabstandet sind. Indem die Aufnahmeelemente als Teil des Rippenrohrblockes gleichzeitig als Minuspol verwendet sind, werden die elektrischen Anschlussmittel auf ein Minimum reduziert, da nur ein gemeinsamer Massekontakt für den gesamten Wärmeübertrager genügt, und für jedes Kontaktplattenpaar ein Weiterer.In a further embodiment of the invention, heating elements rest on both flat sides of the receiving elements, the respective contact plates being spaced apart from one another by at least one spring element. By using the receiving elements as part of the finned tube block as a negative pole at the same time, the electrical connection means are reduced to a minimum, since only one common ground contact is sufficient for the entire heat exchanger, and another for each contact plate pair.
In weiterer Ausgestaltung der Erfindung bestehen die Isolationselemente aus einem temperaturbeständigen Kunststoff, vorzugsweise Polyurethan, Polyamid oder Polypropylen. Dabei handelt sich um Materialien, die in Heizungsanlagen für Kraftfahrzeuge bereits Verwendung finden, so dass im Falle eines späteren Recyclings kein zusätzlicher Werkstoff anfällt.In a further embodiment of the invention, the insulation elements consist of a temperature-resistant plastic, preferably polyurethane, polyamide or polypropylene. These are materials that are already used in heating systems for motor vehicles, so that no additional material is required in the event of subsequent recycling.
Weitere vorteilhafte Ausgestaltungen ergeben sich aus den weiteren Unteransprüchen.Further advantageous configurations result from the further subclaims.
