Description

Die Erfindung betrifft eine Lüfteranlage für ein Kühlsystem eines Kraftfahrzeugs mit mindestens zwei Lüftern, die jeweils einen in einem separaten Gehäuse angeordneten elektrischen Lüftermotor und ein durch diesen antreibbares Lüfterrad umfassen, und mit einer Steuereinheit zum Betreiben der Lüftermotoren.The invention relates to a fan system for a cooling system of a motor vehicle with at least two fans, each comprising a arranged in a separate housing electric fan motor and a driven by this fan, and with a control unit for operating the fan motors.

Derartige Lüfteranlagen sind aus dem Stand der Technik bekannt. Ein Beispiel ist in dem Dokument US 5 947 189 dargestellt. Sie werden üblicherweise dazu eingesetzt, großflächige Kühler in einem Kraftfahrzeug mit der notwendigen Kühlluft zu versorgen, insbesondere wenn eine erhöhte Kühlleistung erforderlich ist.Such fan systems are known from the prior art. An example is in the document US 5,947,189 shown. They are usually used to supply large-area radiator in a motor vehicle with the necessary cooling air, especially when an increased cooling capacity is required.

Bei derartigen Lüfteranlagen sind üblicherweise die Lüfter vor oder nach dem Kühler angeordnet, um den Luftstrom durch den Kühler zu erzeugen. Ferner werden die Lüfter durch eine oder zwei Steuereinheiten angesteuert, die separat im Motorraum angeordnet sind.In such fan systems, the fans are usually arranged before or after the radiator to produce the air flow through the radiator. Furthermore, the fans are controlled by one or two control units, which are arranged separately in the engine compartment.

Der Erfindung liegt die Aufgabe zugrunde, eine Lüfteranlage der gattungsgemäßen Art derart zu verbessern, daß diese möglichst einfach und möglichst kostengünstig ausgebildet ist.The invention has for its object to improve a fan system of the generic type such that it is as simple and inexpensive as possible.

Diese Aufgabe wird bei einer Lüfteranlage der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß die Steuereinheit in dem Gehäuse von einem der Lüfter angeordnet ist und sowohl den in diesem Gehäuse angeordneten Lüftermotor als auch den Lüftermotor des anderen Lüfters betreibt.This object is achieved according to the invention in a fan system of the type described above, that the control unit in the housing of one of the fans is arranged and operates both the fan motor arranged in this housing and the fan motor of the other fan.

Der Vorteil der erfindungsgemäßen Lösung ist darin zu sehen, daß mit dieser Lösung zum einen das separat im Motorraum anzuordnende Steuergerät entfällt und somit ein Gerät weniger im Motorraum montiert werden muß, so daß insbesondere bei beengten Raumverhältnissen ein Gewinn hinsichtlich des Platzbedarfs gegeben ist.The advantage of the solution according to the invention is the fact that with this solution on the one hand separately to be arranged in the engine compartment control unit and thus a device less in the engine compartment must be installed, so that in particular in confined spaces, a gain in terms of space is given.

Darüber hinaus läßt sich durch die Anordnung der Steuereinheit in dem Gehäuse eines der Lüfter auch die Anzahl der Leitungen vereinfachen, da lediglich zu dem einen Lüfter eine Zuleitung zur Speisung der Lüfteranlage zu legen ist und von diesem Lüfter zum anderen Lüfter eine Versorgungsleitung.In addition, can be simplified by the arrangement of the control unit in the housing of the fan and the number of lines, since only to the one fan a supply line to power the fan system is to lay and from this fan to the other fan a supply line.

Darüber hinaus ist ein weiterer Vorteil der erfindungsgemäßen Lösung darin zu sehen, daß mit der Anordnung der Steuereinheit im Gehäuse eines der Lüfter sich in einfacher Weise auch definierte Verhältnisse für die Kühlung der Steuereinheit erreichen lassen, so daß die gesamte Problematik betreffend die Kühlung eines zusätzlichen separat im Motorraum angeordneten Steuergeräts entfällt.In addition, another advantage of the inventive solution is the fact that can be achieved with the arrangement of the control unit in the housing of the fan in a simple manner also defined ratios for the cooling of the control unit, so that the entire problem concerning the cooling of an additional separately arranged in the engine compartment control unit is eliminated.

Außerdem läßt sich vorteilhafterweise die Steuereinheit in das Gehäuse des einen Lüfters integrieren, ohne daß dessen Volumen nennenswert steigt, so daß damit ein erheblicher Raumgewinn im Motorraum des Kraftfahrzeugs erzielbar ist.In addition, advantageously, the control unit can be integrated into the housing of a fan without its volume increases appreciably, so that thus a significant gain in space in the engine compartment of the motor vehicle can be achieved.

Schließlich läßt sich durch die Integration der Steuereinheit in dem Gehäuse des einen Lüfters noch zusätzlich eine Verbesserung hinsichtlich der elektromagnetischen Verträglichkeit erreichen, da alle für Störungen im Bordnetz gegebenenfalls verantwortlichen Komponenten, wie Lüftermotoren und Steuereinheit, möglichst kompakt zusammengefaßt und somit besser abschirmbar sind und somit insgesamt ein geringeres Störpotential im Kraftfahrzeug aufweisen.Finally, can be achieved by the integration of the control unit in the housing of a fan additionally an improvement in terms of electromagnetic compatibility, since all possibly responsible for faults in the electrical system components such as fan motors and control unit summarized as compact and thus better shielded and thus total have a lower potential for interference in the motor vehicle.

Eine besonders vorteilhafte , Lösung sieht vor, daß die Lüfteranlage einen Kabelbaum umfaßt, welcher mit beiden Lüftern verbindbar ist und eine Anschlußsteckverbindung mit einem Versorgungsanschluß und einem externen Anschluß aufweist.A particularly advantageous solution provides that the fan system comprises a cable harness which is connectable to both fans and has a connection plug connection with a supply connection and an external connection.

Durch diesen einen Kabelbaum lassen sich somit die bei der bisher bekannten Lösung insgesamt drei Kabel mit jeweils zwei Steckern ersetzen, so daß bereits auf seiten der Versorgungsleitungen eine erhebliche Vereinfachung möglich ist.By this one cable harness can thus be replaced in the previously known solution a total of three cables with two plugs, so that even on the side of the supply lines a considerable simplification is possible.

Besonders vorteilhaft ist es dabei, wenn der Kabelbaum über eine Steckverbindung mit jedem der Lüfter verbindbar ist.It is particularly advantageous if the cable harness is connectable via a plug connection with each of the fans.

Vorzugsweise ist der Kabelbaum dabei so aufgebaut, daß er eine zwischen den Lüftern verlaufende Verbindungsleitung mit einer Speiseleitung aufweist.Preferably, the cable harness is constructed so that it has a running between the fans connecting line with a feed line.

Prinzipiell wäre eine einzige Speiseleitung ausreichend, sofern eine gute massenseitige Verbindung zwischen den Lüftern über die übliche Einbausituation im Kraftfahrzeug möglich ist.In principle, a single feed line would be sufficient if a good mass-side connection between the fans on the usual installation situation in the vehicle is possible.

Um jedoch hinsichtlich der Entstörung eine möglichst vorteilhafte elektrische Lösung zu erhalten, ist vorzugsweise vorgesehen, daß die Verbindungsleitung auch eine Masseleitung aufweist, um in vorteilhafter Weise eine möglichst gute Masseverbindung zwischen der Steuereinheit und dem Lüftermotor zu erreichen, welcher nicht im selben Gehäuse wie die Steuereinheit angeordnet ist.However, in order to obtain the best possible electrical solution in terms of interference suppression, it is preferably provided that the connecting line also has a ground line in order to advantageously achieve the best possible ground connection between the control unit and the fan motor, which is not in the same housing as the control unit is arranged.

Besonders zweckmäßig ist es ferner, wenn der Kabelbaum eine von dem mit der Steuereinheit versehenen Lüfter zu der Anschlußsteckverbindung verlaufende Versorgungsleitung mit einer Speiseleitung und einer Eingabeleitung aufweist.It is further particularly expedient if the wiring harness has a supply line extending from the fan provided with the control unit to the connection plug connection with a feed line and an input line.

Prinzipiell wäre es ebenfalls nicht notwendig, hier eine separate Masseleitung vorzusehen. Hinsichtlich der Störsicherheit ist es jedoch ebenfalls günstig, wenn die Versorgungsleitung eine Masseleitung aufweist.In principle, it would also not be necessary to provide a separate ground line here. With regard to noise immunity, however, it is also advantageous if the supply line has a ground line.

Eine besonders einfache Lösung sieht vor, daß die Versorgungsleitung und die Verbindungsleitung einen zusammenhängenden Kabelbaum bilden und somit beide Leitungen über eine gemeinsame Steckverbindung mit dem mit der Steuereinheit versehen Lüfter und über eine weitere Steckverbindung mit dem anderen Lüfter verbindbar sind, so daß insgesamt ein derartiger Kabelbaum der erfindungsgemäßen Lüfteranlage insgesamt lediglich drei Steckverbindungen, nämlich die gemeinsame Anschlußsteckverbindung und jeweils eine Steckverbindung zur Herstellung der Verbindung mit jedem der Lüfter umfassen muß, wobei im Falle des mit der Steuereinheit versehenen Lüfters gleichzeitig eine Verbindung mit der Steuereinheit herstellbar ist.A particularly simple solution provides that the supply line and the connecting line form a coherent cable harness and thus both lines are connected via a common connector with the fan provided with the control unit and a further connector with the other fan, so that a total of such a harness the fan system according to the invention a total of only three connectors, namely the common connection plug connection and a plug connection for establishing the connection with each of the fans must include, in the case of the fan provided with the control unit simultaneously with the control unit can be produced.

Hinsichtlich der Ausbildung der Steuereinheit wurden im Zusammenhang mit der bisherigen Erläuterung der erfindungsgemäßen Lüfteranlage keine näheren Angaben gemacht. So sieht eine besonders einfache und daher kostengünstige Lösung vor, daß die Steuereinheit eine gemeinsame Endstufe für den Betrieb aller Lüftermotoren umfaßt, so daß damit alle Lüftermotoren über dieselbe Endstufe, vorzugsweise in Parallelschaltung, betreibbar sind.With regard to the design of the control unit, no further details were given in connection with the previous explanation of the fan system according to the invention. Thus, a particularly simple and therefore cost-effective solution provides that the control unit comprises a common output stage for the operation of all fan motors, so that all the fan motors can be operated via the same output stage, preferably in parallel connection.

Diese Lösung ist hinsichtlich der erforderlichen Bauteile äußerst kostengünstig, bringt jedoch Einschränkungen insbesondere im Fall der Überwachung dieser Lüftermotoren und im Fall einer eventuell erforderlichen separaten Ansteuerung.This solution is extremely cost effective in terms of the required components, but brings limitations in particular in the case of monitoring these fan motors and in the event of a possibly required separate control.

Eine alternative Lösung der erfindungsgemäßen Lüfteranlage sieht daher vor, daß die Steuereinheit für den Betrieb von jedem der Lüftermotoren eine eigene Endstufe umfaßt, wobei die der Zahl der Lüftermotoren entsprechenden Endstufen der Steuereinheit ebenfalls in dem Gehäuse eines der Lüfter angeordnet sind und der andere Lüfter von der für diesen vorgesehenen Endstufe über den Kabelbaum versorgt wird und somit keinerlei Steuerelektronik aufweist.An alternative solution of the fan system according to the invention therefore provides that the control unit for the operation of each of the fan motors includes its own power amplifier, wherein the number of fan motors corresponding power amplifiers of the control unit are also arranged in the housing of the fan and the other fan of the is supplied for this intended power amplifier via the wiring harness and thus has no control electronics.

Hinsichtlich der Kühlung der Steuereinheit wurden im Zusammenhang mit den bisher beschriebenen Lösungen keine näheren Angaben gemacht. So sieht eine vorteilhafte Lösung vor, daß die Steuereinheit mit einem Kühlkörper thermisch gekoppelt ist und somit über diesen Kühlkörper die Wärme der Steuereinheit abführbar ist.With regard to the cooling of the control unit, no further details were given in connection with the solutions described so far. Thus, an advantageous solution provides that the control unit is thermally coupled to a heat sink and thus the heat of the control unit can be discharged via this heat sink.

Vorzugsweise entsteht dabei die Wärme in der Endstufe zur Steuereinheit, so daß es besonders günstig ist, wenn jede Endstufe mit dem Kühlkörper thermisch gekoppelt ist.Preferably, the heat is generated in the final stage to the control unit, so that it is particularly advantageous if each output stage is thermally coupled to the heat sink.

Vorzugsweise erfolgt insbesondere eine thermische Kopplung eines elektronischen Schalters der Endstufe mit dem Kühlkörper und einer diesem zugeordneten Freilaufdiode mit dem Kühlkörper.Preferably, in particular, a thermal coupling of an electronic switch of the output stage with the heat sink and a freewheeling diode associated therewith with the heat sink.

Hinsichtlich der Gestaltung des Kühlkörpers wurden bislang keine näheren Angaben gemacht. Prinzipiell könnte die Kühlung des Kühlkörpers selbst in unterschiedlichster Art und Weise erfolgen. Insbesondere da jedoch der Kühlkörper an einem der Lüfter angeordnet ist, ist es besonders günstig; wenn der Kühlkörper luftgekühlt ist.With regard to the design of the heat sink so far no details have been made. In principle, the cooling of the heat sink could be done even in different ways. In particular, however, since the heat sink is arranged on one of the fans, it is particularly favorable; when the heat sink is air-cooled.

Hierzu ist zweckmäßigerweise der Kühlkörper mit einem Kühlrippenkörper versehen, um eine möglichst große Oberfläche zur Wärmeabgabe an den Luftstrom zu erreichen.For this purpose, the heat sink is expediently provided with a cooling fin body in order to achieve the largest possible surface area for heat dissipation to the air flow.

Insbesondere im Fall mehrerer Endstufen ist es zweckmäßig, wenn jede der Endstufen mit einem eigenen Kühlrippenkörper gekoppelt ist, so daß die Wärme jeder der Endstufen in besonders effizienter Weise abgeführt werden kann.Particularly in the case of several output stages, it is expedient if each of the output stages is coupled to its own fin body, so that the heat of each of the output stages can be dissipated in a particularly efficient manner.

Hinsichtlich der Luftkühlung wäre es beispielsweise denkbar, den Kühlkörper so anzuordnen, daß dieser an einer Außenseite des Gehäuses angeordnet ist oder aus dem Gehäuse herausragt und von dem von dem. Lüfterrad erzeugten und den Kühler durchsetzenden Luftstrom angeströmt und gekühlt ist.With regard to the air cooling, it would be conceivable, for example, to arrange the heat sink so that it is arranged on an outer side of the housing or protrudes from the housing and of which of the. Fan generated and the radiator passing through the air flow is streamed and cooled.

Eine besonders effiziente Kühlung des Kühlkörpers ergibt sich jedoch dann, wenn das Gehäuse des mit der Steuereinheit versehenen Lüfters durch einen vom Lüfterrad erzeugbaren Luftstrom durchströmt ist und der Kühlkörper von dem Luftstrom angeströmt ist. Damit läßt sich die erfindungsgemäße Steuereinheit besonders effizient kühlen.A particularly efficient cooling of the heat sink, however, results when the housing of the fan provided with the control unit is flowed through by an airflow that can be generated by the fan and the cooling body is flown by the air flow. Thus, the control unit according to the invention can be cooled particularly efficiently.

Der Vorteil dieser Lösung ist darin zu sehen, daß der das Gehäuse durchströmende Luftstrom, welcher insbesondere auch zum Kühlen des Lüftermotors selbst dient, dazu eingesetzt werden kann, die Steuereinheit zu kühlen und somit eine Kühlung der Steuereinheit mit einem der Leistung des Lüfters entsprechenden erzwungenen Luftstrom möglich ist, so daß dadurch stets definierte Verhältnisse bei der Kühlung der Steuereinheit erreicht werden, ohne daß besondere Maßnahmen erforderlich sind, denn üblicherweise wird bei derartigen Lüftern das Gehäuse ohnehin durch einen erzwungenen Luftstrom zur Kühlung des Lüftermotors durchsetzt, so daß sich bei der erfindungsgemäßen Lösung zwangsläufig auch eine gezielte und definierte Kühlung der Steuereinheit ergibt, ohne daß zusätzliche Maßnahmen erforderlich sind.The advantage of this solution is the fact that the air flowing through the housing, which also serves in particular for cooling the fan motor itself, can be used to cool the control unit and thus cooling the control unit with a forced air flow corresponding to the performance of the fan is possible, so that thereby always defined conditions are achieved in the cooling of the control unit, without special measures are required, because usually in such fans, the housing is penetrated anyway by a forced air flow for cooling the fan motor, so that in the inventive solution inevitably results in a targeted and defined cooling of the control unit, without additional measures are required.

Eine besonders zweckmäßige Kühlung läßt sich dadurch erreichen, daß der Kühlkörper im Bereich einer Luftöffnung des Gehäuses angeordnet ist, durch die der Luftstrom hindurchtritt.A particularly expedient cooling can be achieved in that the heat sink is arranged in the region of an air opening of the housing, through which the air flow passes.

Vorzugsweise liegt dabei die Luftöffnung in einem Wandbereich des Gehäuses, welcher die Steuereinheit umgibt.In this case, the air opening preferably lies in a wall region of the housing which surrounds the control unit.

Hinsichtlich des Aufbaus der Steuereinheit selbst wurden im Zusammenhang mit der bisherigen Erläuterung der einzelnen Ausführungsbeispiele keine näheren Angaben gemacht. So sieht ein besonders vorteilhaftes Ausführungsbeispiel vor, daß die Steuereinheit eine Schaltungsplatine aufweist, welche sich in einer quer zur Drehachse des Lüftermotors verlaufenden Ebene erstreckt. Eine derartige Anordnung der Schaltungsplatine im Gehäuse des Lüfters hat den großen Vorteil, daß sich in dieser die Steuereinheit sehr raumsparend unterbringen läßt.With regard to the construction of the control unit itself were in connection with the previous explanation of the individual embodiments no details provided. Thus, a particularly advantageous embodiment provides that the control unit has a circuit board which extends in a direction transverse to the axis of rotation of the fan motor plane. Such an arrangement of the circuit board in the housing of the fan has the great advantage that can be accommodated very space-saving in this control unit.

Besonders raumsparend ist diese Lösung, wenn die Schaltungsplatine Stromzuführungen für einen Kommutator des Lüftermotors trägt, so daß keine selbständige Trägeranordnung für die Stromzuführungen für den Kommutator erfolgen muß, sondern diese unmittelbar auf der Schaltungsplatine sitzen und somit auch in einfacher Weise elektrisch mit der Schaltungsplatine verbunden werden können.This solution is particularly space-saving if the circuit board carries power supply lines for a commutator of the fan motor, so that no independent carrier assembly for the power supply to the commutator must be done, but they sit directly on the circuit board and thus are also connected in a simple manner with the circuit board can.

Derartige Stromzuführungen können in beliebiger Weise ausgebildet sein. Besonders günstig ist es, wenn die Stromzuführungen auf der Schaltungsplatine angeordnete Kohlebürstenhalter und gegenüber diesen bewegbare Kohlebürsten aufweisen.Such power supplies may be formed in any manner. It is particularly advantageous if the power supply lines have carbon brush holders arranged on the circuit board and brushes that are movable relative to these.

Um auch die im Bereich der Stromzuführungen für den Kommutator entstehende Wärme möglichst vorteilhaft abzuleiten ist vorzugsweise vorgesehen, daß die Stromzuführungen thermisch mit dem Kühlkörper gekoppelt sind.In order to dissipate as well as possible the heat generated in the region of the power supply lines for the commutator, it is preferably provided that the power supply lines are thermally coupled to the heat sink.

Ein in Fig. 1 dargestelltes erstes Ausführungsbeispiel einer erfindungsgemäßen Lüfteranlage für ein Kühlsystem, insbesondere ein Kühlsystem eines Kraftfahrzeugs umfaßt einen ersten Lüfter 10 und einen zweiten Lüfter 20, die vorzugsweise an einem gemeinsamen Träger 30 gehalten sind.A illustrated in Fig. 1 first embodiment of a fan system according to the invention for a cooling system, in particular a cooling system of a motor vehicle comprises a first fan 10 and a second fan 20, which are preferably held on a common carrier 30.

Der erste Lüfter 10 umfaßt ein erstes Gehäuse 12, in welchem ein erster Lüftermotor 14 angeordnet ist, der dazu dient, ein erstes Lüfterrad 16 anzutreiben.The first fan 10 comprises a first housing 12, in which a first fan motor 14 is arranged, which serves to drive a first fan 16.

Der zweite Lüfter 20 umfaßt ein zweites Gehäuse 22, in welchem ein zweiter Lüftermotor 24 angeordnet ist, der dazu dient, ein zweites Lüfterrad 26 anzutreiben.The second fan 20 includes a second housing 22 in which a second fan motor 24 is arranged, which serves to drive a second fan 26.

Vorzugsweise dient die erfindungsgemäße Lüfteranlage zur Kühlung eines beispielsweise rechteckförmigen Kraftfahrzeugkühlers, welcher durch den Träger 30 abdeckbar ist, wobei mit dem ersten Lüfter 10 Luft durch eine erste Lüfteröffnung 32 des Trägers 30 hindurchgeblasen wird, während mit dem zweiten Lüfter 20 Luft durch eine zweite Lüfteröffnung 34 des Trägers 30 hindurchgeblasen wird.Preferably, the fan system according to the invention is used for cooling a rectangular motor vehicle radiator, for example, which can be covered by the carrier 30, wherein air is blown through a first fan opening 32 of the carrier 30 with the first fan 10, while air is blown through a second fan opening 34 with the second fan 20 the carrier 30 is blown through.

Wie in Fig. 2 dargestellt, sind der erste Lüftermotor 14 und der zweite Lüftermotor 24 durch eine gemeinsame Steuereinheit 40 betreibbar, welche im Fall des ersten Ausführungsbeispiels eine Endstufe 42 aufweist, die sowohl den ersten Lüftermotor 14 als auch den, diesem parallel geschalteten, zweiten Lüftermotor 24 speist.As shown in Fig. 2, the first fan motor 14 and the second fan motor 24 are operable by a common control unit 40, which in the case of the first embodiment, an output stage 42 which feeds both the first fan motor 14 and the second fan motor 24, which is connected in parallel therewith.

Die Endstufe 42 weist beispielsweise einen elektronischen Schalttransistor 44 sowie eine Freilaufdiode 46 auf, wobei der elektronische Schalter 44 zwischen einem Speiseanschluß 48 der Steuereinheit 40 und Speiseleitungen 14a bzw. 24a der Lüftermotoren 14 bzw. 24 liegt und diese getaktet speist, während die Freilaufdiode 46 bei abgeschaltetem elektronischem Schalter 44 den durch die Induktivität der Lüftermotoren 14 und 24 bedingten Stromfluß übernimmt.The output stage 42 has, for example, an electronic switching transistor 44 and a freewheeling diode 46, wherein the electronic switch 44 is located between a supply terminal 48 of the control unit 40 and feed lines 14a and 24a of the fan motors 14 and 24 and these clocked fed while the freewheeling diode 46 at switched off electronic switch 44 takes over the conditional by the inductance of the fan motors 14 and 24 current flow.

Ferner sind die Lüftermotoren 14 und 24 mit Masseleitungen 14b und 24b mit einem Masseanschluß 50 der Steuereinheit 40 verbunden.Further, the fan motors 14 and 24 are connected to ground lines 14b and 24b to a ground terminal 50 of the control unit 40.

Der elektronische Schalter 44 wird über eine Steuerleitung 52 von einer Ansteuereinheit 54 angesteuert, die ihrerseits durch eine Logikschaltung 56 betreibbar ist, wobei mit der Logikschaltung 56 die Ansteuereinheit 54 so betreibbar ist, daß sie den elektronischen Schalter 44 mit einem pulsweitenmodulierten Signal betreibt, wobei die aufgenommene elektrische Leistung der Lüftermotoren 14 und 24 durch die Pulsweite vorgebbar ist.The electronic switch 44 is controlled via a control line 52 by a drive unit 54, which in turn is operable by a logic circuit 56, wherein the logic circuit 56, the drive unit 54 is operable to operate the electronic switch 44 with a pulse width modulated signal, the recorded electric power of the fan motors 14 and 24 can be predetermined by the pulse width.

Der Logikschaltung 56 sind dabei über eine Eingabeleitung 58 Größen vorgebbar, aufgrund derer eine Ermittlung der Parameter zur Festlegung des pulsweitenmodulierten Signals zur Ansteuerung des elektronischen Schalters 44 erfolgt.The logic circuit 56 can be predetermined via an input line 58 sizes, due to which a determination of the parameters for determining the pulse width modulated signal to control the electronic switch 44 is performed.

Bei dem ersten Ausführungsbeispiel der erfindungsgemäßen Lüfteranlage ist, wie in Fig. 3 dargestellt, die Endstufe 42 mit dem elektronischen Schalter 44 und der Freilaufdiode 46 auf einer Schaltungsplatine 60 angeordnet, welche in das erste Gehäuse 12 des ersten Lüfters 10 einsetzbar ist, wobei die Schaltungsplatine 60 nicht nur die Endstufe 42 trägt, sondern gleichzeitig die Ansteuereinheit 54 und die Logikschaltung 56, so daß die gesamte Steuereinheit 40 in dem ersten Gehäuse 12 des ersten Lüfters 10 angeordnet ist.In the first embodiment of the fan system according to the invention, as shown in Fig. 3, the output stage 42 with the electronic switch 44th and the freewheeling diode 46 disposed on a circuit board 60 which is insertable into the first housing 12 of the first fan 10, wherein the circuit board 60 carries not only the output stage 42, but simultaneously the drive unit 54 and the logic circuit 56, so that the entire control unit 40 is disposed in the first housing 12 of the first fan 10.

Die Schaltungsplatine 60 ist zum raumsparenden Unterbringen der Bauteile der Steuereinheit 40 vorzugsweise so in dem Gehäuse 12 angeordnet, daß sie sich in einer Ebene 61 erstreckt, welche quer zu einer Drehachse des ersten Lüftermotors 14 verläuft.The circuit board 60 is preferably arranged in the housing 12 for space-saving accommodation of the components of the control unit 40 so that it extends in a plane 61 which extends transversely to a rotational axis of the first fan motor 14.

Um ferner noch die Bauweise möglichst kompakt zu gestalten, sind auf der Schaltungsplatine 60 außerdem noch Stromzuführungen 62 und 64 für einen in Fig. 5 dargestellten Kommutator 66 des ersten Lüftermotors 14 vorgesehen.Furthermore, in order to make the design as compact as possible, power supply lines 62 and 64 for a commutator 66 of the first fan motor 14 shown in FIG. 5 are also provided on the circuit board 60.

Ferner sitzt auf der Schaltungsplatine 60 noch ein Steckanschluß 68, über welchen eine Verbindung sowohl mit dem Speiseanschluß 48 als auch dem Masseanschluß 50 sowie eine Verbindung der Endstufe 42 mit dem zweiten Lüftermotor 24, zu welchem die Speiseleitung 24a und die Masseleitung 24b führen, erfolgt, so daß in dem zweiten Gehäuse 22 des zweiten Lüfters 20 keinerlei elektronische Baugruppe vorgesehen ist.Furthermore, sits on the circuit board 60 is still a plug connection 68, via which a connection with both the supply terminal 48 and the ground terminal 50 and a connection of the power amplifier 42 to the second fan motor 24, to which the feed line 24a and the ground line 24b lead takes place, so that no electronic assembly is provided in the second housing 22 of the second fan 20.

Zur Kühlung der Steuereinheit 40 ist, wie in Fig. 3 und 4 dargestellt, ein Kühlkörper 70 vorgesehen, mit welchem insbesondere der elektronische Schalter 44 und die Freilaufdiode 46 thermisch gekoppelt sind. Vorzugsweise ist aber auch noch eine thermische Kopplung zu den Stromzuführungen 62 und 64 und dem Kühlkörper 70 vorgesehen.For cooling the control unit 40, as shown in FIGS. 3 and 4, a cooling body 70 is provided, with which, in particular, the electronic switch 44 and the freewheeling diode 46 are thermally coupled. Preferably, however, a thermal coupling to the power supply lines 62 and 64 and the heat sink 70 is also provided.

Insbesondere ist jede der Stromzuführungen 62, 64 mit einem fest auf der Schaltungsplatine 60 angeordneten Kohlebürstenhalter 62a bzw. 64a und einer beweglich in dem jeweiligen Kohlebürstenhalter 62a, 64a angeordneten Kohlebürste 62b, 64b versehen, welch letztere den Kommutator kontaktieren.In particular, each of the power supply lines 62, 64 is provided with a carbon brush holder 62a, 64a fixedly mounted on the circuit board 60 and a carbon brush 62b, 64b movably disposed in the respective carbon brush holder 62a, 64a, which contact the commutator.

Der Kühlkörper 70 umfaßt seinerseits beispielsweise einen Kühlrippenkörper 72, welcher vorzugsweise so ausgebildet ist, daß er von einem durch eine Luftöffnung 74 in das erste Gehäuse 12 einströmenden Luftstrom 76 kühlbar ist, wobei der Luftstrom 76 den Kühlrippenkörper 72 durchströmt und vorzugsweise auch einen Stator 78 und einen Rotor 80 des ersten Lüftermotors 14 zur Kühlung derselben durchströmt.The heat sink 70 in turn comprises, for example, a cooling fin body 72, which is preferably designed so that it can be cooled by an air opening 74 flowing through an air opening 74 in the first housing 12 air stream 76, wherein the air flow 76 flows through the cooling fin body 72 and preferably also a stator 78 and a rotor 80 of the first fan motor 14 flows through for cooling the same.

Zweckmäßigerweise durchströmt der Luftstrom 76 zunächst den Kühlrippenkörper 72, tritt dann in einem rückseitigen Bereich des Lüftermotors 14 in diesen ein, durchströmt diesen und tritt aus einem vorderseitigen Bereich 84 des ersten Lüftermotors 14 wieder aus diesem aus. Dabei erreicht der Luftstrom 76 einen den vorderseitigen Bereich 84 des ersten Lüftermotors 14 mit einem Boden 86 übergreifenden Lüftertopf 88, wobei der Boden 86 den Luftstrom 76 umlenkt und Lamellen 90 des Lüftertopfes 88 zuführt, welche den Luftstrom 76 in radialer Richtung zu einer Drehachse 92 des Rotors 80 beschleunigen und auf einer dem Boden 86 abgewandten Seite des Lüftertopfes 88 radial außerhalb des ersten Gehäuses 12 austreten lassen.Expediently, the air flow 76 first flows through the cooling fin body 72, then enters into a rear region of the fan motor 14, flows through the latter and exits from a front region 84 of the first fan motor 14 again. In this case, the air flow reaches a 76 the front side region 84 of the first fan motor 14 with a bottom 86 cross fan cup 88, the bottom 86 deflects the air stream 76 and fins 90 of the fan cup 88 feeds the air flow 76 in the radial direction to a rotational axis 92 of the To accelerate rotor 80 and leave on a side facing away from the bottom 86 of the fan pot 88 radially outside the first housing 12.

Der Lüftertopf 88 wirkt somit durch Erzeugung eines Unterdrucks im Lüftertopf 88 aufgrund seiner Lamellen 90 als den Luftstrom 76 erzwingendes Motorlüfterrad, welches einen Teilbereich des ersten Lüfterrades 16 darstellt, wobei letzteres insbesondere mit außerhalb des Lüftertopfes 88 angeordneten Flügeln 94 die Luft beschleunigt, welche durch die erste Lüfteröffnung 32 des Trägers 30 hindurchtreten soll.The fan cup 88 thus acts by generating a negative pressure in the fan chamber 88 due to its fins 90 as the air flow 76 compelling motor fan, which is a portion of the first fan 16, wherein the latter, in particular with wings 94 arranged outside the fan pot 88, accelerates the air which is to pass through the first fan opening 32 of the carrier 30.

Der durch den Lüftertopf 88 erzwungene Luftstrom 76 dient somit nicht nur dazu, in bekannter Weise den Lüftermotor 14 definiert zu kühlen, sondern gleichzeitig auch dazu, über den Kühlrippenkörper 72 den Kühlkörper 70 zu kühlen, der seinerseits wiederum den elektronischen Schalter 44 und die Freilaufdiode 46 kühlt, welche die am meisten Wärme erzeugenden Leistungsbauteile der Endstufe 42 darstellen.The forced through the fan chamber 88 air flow 76 thus not only serves to cool the fan motor 14 defined manner in a known manner, but at the same time to cool the cooling body 70 via the cooling fin body 72, in turn, the electronic switch 44 and the freewheeling diode 46th cool, which are the most heat generating power components of the power amplifier 42.

Ferner ist der Kühlkörper 70 vorzugsweise noch mit einem Bügel 96 versehen, welcher von dem dem Steckanschluß 68 gegenüberliegend angeordneten Kühlrippenkörper 72 bis zum Steckanschluß 68 verläuft und Haltestege 98 zur Abstützung an der Schaltungsplatine 60 aufweist.Further, the heat sink 70 is preferably still provided with a bracket 96 which extends from the plug-in connection 68 opposite arranged cooling fin body 72 to the plug connection 68 and holding webs 98 for support on the circuit board 60 has.

Vorzugsweise sind der Kühlrippenkörper 72 und der Bügel 96 ein insgesamt einstückiges Teil, an welchem die Schaltungsplatine 60 fixiert ist.Preferably, the fin body 72 and the bracket 96 are a total integral part to which the circuit board 60 is fixed.

Insbesondere läßt sich die Steuereinheit 14 so in das erste Gehäuse einsetzen, daß der Kühlrippenkörper 72 mit äußeren Enden 102 seiner Kühlrippen 100 in der Luftöffnung 74 des ersten Gehäuses 12 liegt.In particular, the control unit 14 can be inserted into the first housing such that the cooling fin body 72 lies with outer ends 102 of its cooling fins 100 in the air opening 74 of the first housing 12.

Ferner ist die gesamte Steuereinheit 40 noch durch einen Gehäusedeckel 104 abgedeckt, welcher das gesamte erste Gehäuse 12 im Bereich eines dem ersten Lüfterrad 16 abgewandten Endes verschließt und somit auch die Schaltungsplatine 60 der Steuereinheit 40 übergreift.Furthermore, the entire control unit 40 is still covered by a housing cover 104, which closes the entire first housing 12 in the region of an end facing away from the first fan 16 and thus also engages over the circuit board 60 of the control unit 40.

Vorzugsweise sind die beiden Lüfter 10 und 20, wie in Fig. 1 dargestellt, mit einem Kabelbaum 106 verbunden, welcher einen Steckverbinder 108 aufweist, der mit dem vorzugsweise über das Gehäuse 68 überstehenden Steckanschluß 68 verbindbar ist, einen Anschlußsteckverbinder 110 aufweist, welcher mit der Bordelektrik des Kraftfahrzeugs verbindbar ist, und einen Steckverbinder 112 aufweist, mit welchem eine elektrische Verbindung zum Lüftermotor 24 des Lüfters 20 herstellbar ist.Preferably, the two fans 10 and 20, as shown in Fig. 1, connected to a wiring harness 106 which has a connector 108 which is connectable to the preferably over the housing 68 projecting plug connector 68, a terminal connector 110 which, with the On-board electrical system of the motor vehicle is connectable, and has a connector 112, with which an electrical connection to the fan motor 24 of the fan 20 can be produced.

Der Kabelbaum 106 umfaßt dabei eine von dem Steckverbinder 108 zum Steckverbinder 112 verlaufende Verbindungsleitung 114, welche, wie in Fig. 2 dargestellt, die Speiseleitung 24a und die Masseleitung 24b umfaßt, die von der Endstufe 42 zum zweiten Lüftermotor 24 des zweiten Lüfters 20 verläuft.The wiring harness 106 in this case comprises a connection line 114 extending from the plug connector 108 to the plug connector 112, which, as shown in FIG. 2, comprises the feed line 24a and the ground line 24b extending from the output stage 42 to the second fan motor 24 of the second fan 20.

Ferner umfaßt der Kabelbaum 106 eine Versorgungsleitung 116, welche von dem Anschlußsteckverbinder 110 zum Steckverbinder 108 verläuft und, wie in Fig. 2 dargestellt, eine von einem ersten Versorgungsanschluß 49 zum Speiseanschluß 48 führende Speiseleitung 48a, eine von einem zweiten Versorgungsanschluß 51 zum Masseanschluß 50 führende Masseleitung 50a und eine von einem externen Anschluß 59 zu einem Eingabeanschluß-58 führende Eingabeleitung 58a aufweist, wobei die Versorgungsanschlüsse 49 und 51 und der externe Anschluß 59 in dem Anschlußsteckverbinder 110 vorgesehen sind und mit dem für die Lüfteranlage vorgesehenen Anschluß verbindbar sind.Furthermore, the wiring harness 106 includes a supply line 116 which extends from the terminal connector 110 to the connector 108 and, as shown in Fig. 2, leading from a first supply terminal 49 to the feed terminal 48 feed line 48a, one of a second supply terminal 51 to the ground terminal 50 leading Ground line 50a and one of an external terminal 59 to an input terminal 58 leading input line 58a, wherein the supply terminals 49 and 51 and the external terminal 59 are provided in the connector 110 and can be connected to the connector provided for the fan system.

Bei einem zweiten Ausführungsbeispiel der erfindungsgemäßen Lüffieranlage, dargestellt in Fig. 6 bis 8, sind diejenigen Elemente, die mit denen des ersten Ausführungsbeispiels verbunden sind, mit denselben Bezugszeichen versehen, so daß hinsichtlich der Beschreibung derselben vollinhaltlich auf das erste Ausführungsbeispiel Bezug genommen werden kann.In a second embodiment of the invention Lüffieranlage shown in Fig. 6 to 8, those elements which are connected to those of the first embodiment, provided with the same reference numerals, so that with respect to the description thereof may be made in full to the first embodiment reference.

Im Gegensatz zum ersten Ausführungsbeispiel der erfindungsgemäßen Lüfteranlage ist bei dem zweiten Ausführungsbeispiel der erfindungsgemäßen Lüfteranlage die Steuereinheit 40' mit einer ersten Endstufe 42a für den ersten Lüftermotor 14 und einer zweiten Endstufe 42b für den zweiten Lüftermotor 24 versehen, wobei jede der Endstufen einen elektronischen Schalter 44a bzw. 44b aufweist und eine Freilaufdiode 46a bzw. 46b, die in gleicher Weise arbeitet wie im Zusammenhang mit dem ersten Ausführungsbeispiel beschrieben.In contrast to the first embodiment of the fan system according to the invention in the second embodiment of the fan system according to the invention, the control unit 40 'is provided with a first output stage 42a for the first fan motor 14 and a second output stage 42b for the second fan motor 24, each of the output stages an electronic switch 44a and 44b and a freewheeling diode 46a and 46b, which operates in the same manner as described in connection with the first embodiment.

Über die Steuerleitungen 52a und 52b sind die elektronischen Schalter 44a und 44b durch die gemeinsame Steuereinheit 54' jeweils mit einem pulsweitenmodulierten Signal ansteuerbar.The electronic switches 44a and 44b can be actuated by the common control unit 54 'via the control lines 52a and 52b, each with a pulse-width-modulated signal.

Allerdings führen bei dem zweiten Ausführungsbeispiel der erfindungsgemäßen Lüfteranlage die Speiseleitung 14a und die Masseleitung 14b zu der ersten Endstufe 42a und die Speiseleitung 24a und die Masseleitung 24b zu der zweiten Endstufe 42b und werden somit getrennt voneinander von den jeweils für die Lüftermotoren 14 und 24 vorgesehenen elektronischen Schaltern 44a bzw. 44b angesteuert.However, in the second embodiment of the fan system according to the invention, the feed line 14a and the ground line 14b to the first output stage 42a and the feed line 24a and the ground line 24b to the second output stage 42b and are thus separated from each other by the respectively provided for the fan motors 14 and 24 electronic Controlled switches 44a and 44b.

Dennoch ist auch bei dem zweiten Ausführungsbeispiel der erfindungsgemäßen Lüfteranlage die gesamte Steuereinheit 40' im ersten Gehäuse 12 des ersten Lüfters 10 angeordnet.Nevertheless, even in the second embodiment of the fan system according to the invention, the entire control unit 40 'in the first housing 12 of the first fan 10 is arranged.

Allerdings ist in diesem Fall der Kühlkörper 70' auf vorzugsweise auf gegenüberliegenden Seiten der Schaltungsplatine 60 mit jeweils einem Kühlrippenkörpers 72a bzw. 72b versehen, wobei jeder Kühlrippenkörper 72a, b einer Endstufe, nämlich der Endstufe 42a bzw. 42b, zugeordnet ist und insbesondere zur Kühlung des jeweiligen elektronischen Schalters 44a bzw. 44b und der entsprechenden Freilaufdiode 46a bzw. 46b dient.However, in this case, the heat sink 70 'on preferably on opposite sides of the circuit board 60 is provided with a respective cooling fin body 72a and 72b, each fin body 72a, b of an output stage, namely the output stage 42a and 42b, is assigned and in particular for cooling of the respective electronic switch 44a or 44b and the corresponding freewheeling diode 46a and 46b, respectively.
