Die Erfindung betrifft ein Kühleizargensystem gemäß dem Oberbegriff des Anspruches 1 und ein Kühlersystem gemäß dem Oberbegriff des Anspruches 15.The invention relates to a Kühleizargensystem according to the preamble of
In Kraftfahrzeugen werden Kühlersysteme eingesetzt, um mittels eines Wärmeübertragers die Abwärme eines Verbrennungsmotors des Kraftfahrzeuges an die Umgebung abzugeben. Durch den Wärmeübertrager strömt Kühlflüssigkeit zur Übertragung der Abwärme des Verbrennungsmotors an den Wärmeübertrager. Ferner kann am Wärmeübertrager ein weiterer als Kondensator ausgebildeter Wärmeübertrager angeordnet sein. An dem Wärmeübertrager ist ein Kühlerzargensystem mit einer Kühlerzarge und einem Lüfter befestigt, Die im Allgemeinen aus Kunststoff hergestellte Kühlerzarge kanalisiert dabei den Luftstrom durch den Wärmeübertrager, wobei durch eine Lüfteröffnung mittels des Lüfters Luft durch den Wärmeübertrager zur Erhöhung der Kühlleistung des Wärmeübertragers gefördert wird. Der Lüfter weist dabei einen Elektromotor, ein Lüfterrad und Lüfterschaufein auf. Der Elektromotor ist dabei an einem Bordnetz des Kraftfahrzeuges mittels elektrischer Leiter in Verbindung zu setzen. Die elektrischen Leiter dienen neben der Versorgung des Elektromotors mit elektrischem Strom auch zur Steuerung des Elektromotors. Die Leiter umfassen damit sowohl Stromleiter als auch Steuerungsleiter zur Steuerung und elektrischen Verbindung des Elektromotors mit einer Schalteinrichtung. Als elektrische Leiter werden Kabel, insbesondere aus Kupfer, eingesetzt.In motor vehicles, radiator systems are used to deliver the waste heat of an internal combustion engine of the motor vehicle to the environment by means of a heat exchanger. Through the heat exchanger coolant flows to transfer the waste heat of the engine to the heat exchanger. Furthermore, a further heat exchanger designed as a condenser can be arranged on the heat exchanger. The Kühlerzargensystem is attached to the heat exchanger with a radiator frame and a fan, the generally made of plastic radiator frame channels the air flow through the heat exchanger, which is promoted by a fan opening by the fan air through the heat exchanger to increase the cooling capacity of the heat exchanger. The fan has an electric motor, a fan and Lüfterschaufein on. The electric motor is to be connected to an electrical system of the motor vehicle by means of electrical conductors in connection. The electrical conductors are used in addition to the supply of the electric motor with electric power and to control the electric motor. The conductors thus include both current conductors and control conductors for the control and electrical connection of the electric motor with a switching device. As electrical conductors cables, in particular copper, are used.
Zur Steuerung der Drehzahl des Elektromotor und damit auch des Lüfters werden Vorwiderstände eingesetzt. Wird der Strom zu dem Elektromotor, durch den Vorwiderstand geleitet, fällt die Spannung im Vorwiderstand ab und damit auch die Drehzahl des Lüfters. Bei einem Leiten des Stromes zu dem Elektromotor und nicht durch den Vorwiderstand wird von dem Vorwiderstand die Spannung nicht abgesenkt und dadurch steht die volle Leistung des Elektromotors zur Verfügung. Als Vorwiderstände werden im Allgemeinen sogenannte Wendelwiderstände eingesetzt. Eine Widerstandswendel ist auf einem zylindrischen Keramikrohr aufgewickelt und mit Zement auf dem Keramikrohr fixiert. An dem Vorwiderstand sind Stromleitungselemente angeordnet zur Stromführung durch den Vorwiderstand.To control the speed of the electric motor and thus the fan resistors are used. If the current to the electric motor, passed through the resistor, the voltage drops in the series resistor and thus the speed of the fan. When the current is conducted to the electric motor and not through the series resistor, the voltage is not lowered by the series resistor and thus the full power of the electric motor is available. As series resistors so-called spiral resistors are generally used. A resistance coil is wound on a cylindrical ceramic tube and fixed with cement on the ceramic tube. At the series resistor power line elements are arranged to conduct current through the series resistor.
Die Vorwiderstände werden zwischen dem Wärmeübertrager und der Kühlerzarge angeordnet. Dadurch ist eine entsprechende Bautiefe in axialer Richtung erforderlich, wobei ausreichende Abstände zu dem Warmeübertrager und der Kühlerzarge aus Kunststoff einzuhalten sind. Der Vorwiderstand ist dabei dahingehend zu positionieren, dass eine ausreichende Kühlung des Vorwiderstandes aufgrund der umgewälzten Luft gewährleistet ist, Dies hat zur Folge, dass die Gesamtbautiefe des Kühlerzargensystems eingeschränkt ist.The series resistors are arranged between the heat exchanger and the radiator frame. As a result, a corresponding depth in the axial direction is required, with sufficient distances to the heat exchanger and the radiator frame made of plastic must be adhered to. The series resistor is to be positioned so that a sufficient cooling of the series resistor is ensured due to the circulating air, this has the consequence that the overall depth of the Kühlerzargensystems is limited.
Die Aufgabe der vorliegende Erfindung besteht deshalb darin, einen Kühterzargensystem und ein Kühlersystem zur Verfügung zu stellen, bei dem der Vorwiderstand des Elektromotor des Lüfters einfach und preiswert unter Beanspruchung eines geringen axialen Bauraumes angeordnet werden kann und ferner eines ausreichende Kühlung des Vorwiderstandes gewährleistet ist. Das Kühlerzargensystem und das Kühlersystem sollen zuverlässig im Betrieb arbeiten.The object of the present invention is therefore to provide a Kühterzargensystem and a radiator system, in which the Series resistance of the electric motor of the fan can be easily and inexpensively under stress of a small axial space can be arranged and further sufficient cooling of the series resistor is ensured. The radiator frame system and the radiator system should operate reliably during operation.

Der Widerstandsstrorrleiter ist dabei von keinem Feststoff oder keiner Flüssigkeit umgeben, so dass die von dem Lüfter umgewälzte Luft oder die Fahrtluft bei dem Kraftfahrzeug unmittelbar auf den Widerstandsstromleiter aufgeleitet werden kann. Damit kann die Abwärme aufgrund der konvektiven Wärmeübertragung von der Luft unmittelbar von dem Widerstandsstromleiter abgeleitet werden. Eine Wärmeleitung durch einen Feststoff oder eine Flüssigkeit, beispielsweise Zement und erst dem anschließenden Ableiten der Wärme nach dem Feststoff oder der Flüssigkeit, die den Widerstandsstromleiter umgibt, ist damit nicht erforderlich. Im Wesentlichen bedeutet dabei, dass wenigstens 60 %, 80 %, 90 % oder 95 % der Abwärme des Widerstandsstromleiters mittels der konvektiven Wärmeübertragung an die Luft abgeleitet ist bzw. ableitbar ist.In particular, the waste heat of the resistance conductor is substantially directly derived from the resistance conductor by means of a convective Wärmaübeftragung to the air The resistance of the resistor Vorsterres has a high electrical resistance, so that drops at the resistance current conductor, the voltage for the electric motor and thereby the electric motor, the desired lower electrical Performs performance and thus the speed of the fan drops. The resistance current conductor is surrounded by no solid or liquid, so that the air circulated by the fan or the travel air in the motor vehicle can be fed directly to the resistance conductor. In order to For example, the waste heat due to the convective heat transfer from the air can be dissipated directly from the resistance conductor. A heat conduction through a solid or a liquid, such as cement and only the subsequent dissipation of the heat after the solid or the liquid surrounding the resistance conductor is therefore not required.

In einer weiteren Ausgestaltung sind die elektrischen Leiter in die Zargenstrebe und/oder die Halteeinrichtung integriert, insbesondere eingespritzt. Die elektrischen Leiter sind in die Zargensirebe und/oder in die Halteeinrichtung, insbesondere in die Haltestreben, integriert, insbesondere eingespritzt.

The electrical conductors are in the Zargensirebe and / or in the holding device, in particular in the support struts, integrated, in particular injected. The electrical conductors need not be arranged on the outside of the frame strut and / or the holding device.
In einer ergänzenden Variante umfasst die Zargenstrebe und/oder die Halteeinrichtung wenigstens ein elektrisches Kontaktelement, insbesondere als Teil eines Steckers. Die Zargenstrebe und/oder die Halteeinrichtung, insbesondere die Zargenstrebe, kann damit als ein gesondertes Bauteil hergestellt werden, das nachträglich auf der mittels Spritzgießen aus Kunststoff hergestellten Kühlerzarge angeordnet wird. In dieser besonderen Zargenstrebe und/oder Halteeinrichtung ist bereits der Vorwiderstand angeordnet und ferner sind in der Zargenstrebe und/oder der Halteeinrichtung bereits die elektrischen Leiter integriert.

In einer weiteren Ausgestaltung besteht der Widerstandsstromleiter wenigstens teilweise, insbesondere vollständig, aus Karbon. Der Widerstandsstromleiter kann damit beliebige Geometrien und eine ausreichend große Oberfläche aufweisen, so dass dadurch der Widerstandsstromleiter flexibel an der Kühlerzarge angeordnet werden kann.In a further embodiment, the resistance current conductor consists at least partially, in particular completely, of carbon. The resistance current conductor can thus have any desired geometries and a sufficiently large surface area, so that the resistance current conductor can thereby be flexibly arranged on the radiator frame.
Insbesondere umfasst das Kohlerzargensystem eine elektrische Schalteinrichtung zur Leitung des Stromes zu dem Elektromotor, so dass der Strom durch den wenigstens einen Vorwiderstand leitbar ist für eine geringe Lüfterleistung oder unter Umgehung des wenigstens einen Vorwiderstandes zu dem Elektromotor leitbar ist für eine hohe Lüfterleistung. Das Kühlerzargensystem kann dabei auch mehrer Vorwiderstände mit einem unterschiedlichen elektrischen Widerstand umfassen, so dass dadurch mittels der elektrischen Schalteinrichtung auch beilspielsweise mehr als drei oder vier elektrische Leistungsstufen des Elektromotors von der elektrischen Schalteinrichtung zur Verfügung gestellt werden können.In particular, the Kohlerzargensystem comprises an electrical switching device for conducting the current to the electric motor, so that the current through the at least one resistor is conductive for low fan power or bypassing the at least one series resistor to the electric motor is conductive for high fan power.

Insgesamt betrachtet sind mit dem erfindungsgemäßen Kühlerzargensystem 1 und dem erfindungsgemäßen Kühlersystem 20 wesentiche Vorteile verbunden. Der Vorwiderstand 3 wird an dem Kühlerzargensystem 1 dahingehend positioniert, dass einerseits ohnehin vorhandener Bauraum an dem Kühlerzargensystem 1 genutzt wird, so dass dadurch für den Vorwiderstand 3 kein zusätzlicher Bauraum benötigt wird. Außerdem ist eine gute Kühlung des Widerstandsstromleiters 4 aufgrund der großen Oberfläche und/oder der Geometrie des Widerstandsstromletters 4 möglich, so dass dadurch ein zuverlässiger Betrieb des Kühlerzargensystems 1 gewährleistet ist. Das in Kraftfahrzeugen eingesetzte Kühlersystem 20 weist damit wesentliche Vorteile auf. Der erforderliche Bauraum für das Kühlersystem 20 kann verringert werden und die Zuverlässigkeit des Vorwiderstandes 3 aufgrund der ausreichenden und guten Kühlung des Widerstandsstromleiters 4 ist gewährleistet.Overall, significant advantages are associated with the inventive
