Description
Die Erfindung betrifft eine Nassläuferpumpe, insbesondere eine Kraftfahrzeugpumpe, die beispielsweise als Kühlwasserpumpe für Kraftfahrzeuge verwendet wird.The invention relates to a wet-running pump, in particular a motor vehicle pump, which is used for example as a cooling water pump for motor vehicles.

Auch die
Nachteilig bei einer derartigen Nassläuferpumpe ist, dass der Aufbau kompliziert und die Montage entsprechend aufwändig ist.The disadvantage of such a wet-running pump is that the structure is complicated and the assembly is correspondingly expensive.
Der Erfindung liegt die Aufgabe zugrunde, eine Nassläuferpumpe zu schaffen, bei welcher der Aufbau vereinfacht ist.The invention has for its object to provide a wet-running pump, in which the structure is simplified.
Die Lösung der Aufgabe erfolgt erfindungsgemäß durch eine Nassläuferpumpe mit den Merkmalen des Anspruchs 1 und den Merkmalen des Anspruchs 3 sowie durch eine Verwendung einer Leiterplatte mit den Merkmalen des Anspruchs 12.The object is achieved by a wet-running pump with the features of claim 1 and the features of claim 3 and by using a printed circuit board having the features of
Die erfindungsgemäße Nassläuferpumpe, bei der es sich insbesondere um eine Pumpe für ein Kraftfahrzeug handeln kann, weist einen Nassbereich und einen Trockenbereich auf. Der Nassbereich wird von einem Fluid, das die Nassläuferpumpe fördert, durchströmt, um die Nassläuferpumpe bzw. einzelne Komponenten der Nassläuferpumpe zu kuhlen. Insbesondere ist in dem Nassbereich ein mit einem Pumpenrad verbundener Rotor vorgesehen. Der Trockenbereich ist von dem Nassbereich getrennt, damit in dem Trockenbereich elektrische Komponenten, insbesondere ein Stator, der mit dem Rotor zusammenwirkt, angeordnet werden können. Erfindungsgemäß ist eine Leiterplatte vorgesehen, die zumindest teilweise den Nassbereich von dem Trockenbereich abgrenzt. Die Leiterplatte weist zur Verbindung mit einem Stator und/ oder zur Ausbildung des Stators elektrische Leitungen auf. Die Leiterplatte kann auch die Stcuerelemente enthalten. Dadurch ist es möglich, dass die Leiterplatte einen ansonsten erforderlichen Spalttopf ersetzt, oder zumindest einen Teil des Spalttopfes bildet, wobei der Spalttopf auch zu einem scheibenförmigen bzw. plattenförmigen Begrenzungselement entartet sein kann. Dadurch, dass die Leiterplatte und der Spalttopf ein gemeinsames Bauteil ausbilden bzw. die Leiterplatte den Spalttopf ersetzt, ist der Aufbau und die Montage der Nassläuferpumpe vereinfacht. Die Leiterplatte kann zusätzlich beschichtet sein, um eine bessere Resistenz gegen das Medium zu erreichen.The wet-running pump according to the invention, which may in particular be a pump for a motor vehicle, has a wet area and a dry area. The wet area is traversed by a fluid that pumps the wet runner pump to cool the wet runner pump or individual components of the wet runner pump. In particular, a rotor connected to a pump wheel is provided in the wet area. The drying area is separated from the wet area, so that in the dry area electrical components, in particular a stator, which cooperates with the rotor, can be arranged. According to the invention, a printed circuit board is provided which at least partially delimits the wet area from the drying area. The printed circuit board has electrical lines for connection to a stator and / or to form the stator. The circuit board may also contain the stub elements. This makes it possible for the printed circuit board to replace an otherwise required split pot, or at least forms part of the split pot, wherein the split pot can also be degenerate to a disc-shaped or plate-shaped limiting element. Due to the fact that the circuit board and the containment shell form a common component or the circuit board replaces the containment shell, the construction and assembly of the wet runner pump is simplified. The printed circuit board may additionally be coated in order to achieve a better resistance to the medium.
In einer unabhängigen Erfindung weist die erfindungsgemäße Nassläuferpumpe, bei der es sich insbesondere um eine Kühlwasserpumpe für ein Kraftfahrzeug handelt, einen mit einem Pumpenrad verbundenen Rotor auf, der mit einem Stator zusammenwirkt. Ferner ist eine Leiterplatte vorgesehen, deren elektrische Leitungen zumindest teilweise den Stator ausbilden. Vorzugsweise ist der mit dem Pumpenrad verbundene Rotor in einem Nassbereich und der Stator in einem Trockenbereich angeordnet, wobei der Nassbereich von dem Trockenbereich durch ein Begrenzungselement, beispielsweise einen Spalttopf, getrennt ist. In diesem Fall ist die Leiterplatte vorzugsweise mit dem Begrenzungselement verbunden, d. h. beispielsweise auf der zum Trockenbereich weisenden Seite des Begrenzungselementes aufgeklebt. Dadurch, dass die Leiterplatte den Stator ganz oder teilweise ausbildet, können einzelne Statoren eingespart bzw. kleiner ausgeführt werden, wodurch der Aufbau und die Montage der Nassläuferpumpe vereinfacht ist.In an independent invention, the wet-running pump according to the invention, which is in particular a cooling water pump for a motor vehicle, has a rotor connected to a pump wheel, which cooperates with a stator. Furthermore, a printed circuit board is provided whose electrical lines at least partially form the stator. Preferably, the rotor connected to the impeller is disposed in a wet area and the stator in a dry area, wherein the wet area is separated from the dry area by a delimiting element, for example a containment shell. In this case, the printed circuit board is preferably connected to the limiting element, that is, for example glued on the side facing the drying area of the limiting element. Due to the fact that the printed circuit board forms all or part of the stator, individual stators can be saved or made smaller, which simplifies the construction and assembly of the wet-running pump.
Das Begrenzungselement bzw. die Leiterplatte ist besonders bevorzugt über die zum Nassbereich weisende Oberfläche des Begrenzungselements bzw. der Leiterplatte mit dem geförderten Fluid der Nassläuferpumpe in Kontakt, so dass die Leiterplatte durch das geförderte Fluid gekühlt wird. Da die elektrischen Leitungen der Leiterplatte in der Regel aus einem metallischen Material, beispielsweise Kupfer, bestehen, weisen die elektrischen Leitungen einen geringen Wärmewiderstand auf, so dass die in dem Stator entstehende Wärme über die gekühlten elektrischen Leitungen abgeführt werden kann. Eine Wärmetransport allein über einen wärmeisolierenden Luftspalt hinweg wird dadurch vermieden, so dass die Kühlung des Stators verbessert ist.The delimiting element or the printed circuit board is particularly preferably in contact with the conveyed fluid of the wet-running pump via the surface of the delimiting element or the printed circuit board pointing toward the wet region, so that the printed circuit board is cooled by the conveyed fluid. Since the electrical lines of the printed circuit board usually consist of a metallic material, for example copper, the electrical lines have a low thermal resistance, so that the heat generated in the stator can be dissipated via the cooled electrical lines. A heat transfer alone across a heat-insulating air gap is thereby avoided, so that the cooling of the stator is improved.
Vorzugsweise weist die Leiterplatte Statorwicklungen des Stators auf, wobei die Statorwicklungen des Stators insbesondere durch die elektrischen Leitungen der Leiterplatte ausgebildet werden. Hierzu sind der Rotor und der Stator bezogen auf eine Drehachse, um die das Pumpenrad und der Rotor rotieren, axial zueinander angeordnet.Preferably, the circuit board to stator windings of the stator, wherein the stator windings of the stator are formed in particular by the electrical lines of the circuit board. For this purpose, the rotor and the stator are arranged axially relative to one another with respect to an axis of rotation about which the impeller and the rotor rotate.
Die Leiterplatte ist vorzugsweise mehrschichtig aufgebaut. Die mindestens eine Zusatzschicht zur Ausbildung der mehrschichtigen Leiterplatte weist insbesondere ebenfalls Statorwicklungen auf. Dadurch ist es möglich, eine mehrschichtige Leiterplatte mit mehreren hintereinander angeordneten Statorwicklungen auszubilden. Vorzugsweise ist der Stator der Nassläuferpumpe vollständig in das Begrenzungselement bzw. in der Leiterplatte integriert.The printed circuit board is preferably constructed in multiple layers. The at least one additional layer for forming the multilayer printed circuit board in particular also has stator windings. This makes it possible to form a multilayer printed circuit board with a plurality of stator windings arranged one behind the other. Preferably, the stator is the Wet runner pump completely integrated in the limiting element or in the printed circuit board.
In einer besonders bevorzugten Ausführungsform ist der bei einer Nassläuferpumpe üblicherweise vorgesehene Spalttopf zu einer Leiterplatte entartet. Die Verwendung einer Leiterplatte als Begrenzungselement, insbesondere als Spalttopf in einer Nassläuferpumpe, stellt eine unabhängige Erfindung dar.In a particularly preferred embodiment, the usually provided in a wet-running pump split pot is degenerate to a circuit board. The use of a printed circuit board as a limiting element, in particular as a containment shell in a wet-running pump, represents an independent invention.
Bei der Leiterplatte handelt es sich insbesondere um eine Elektroplatine mit aufgedruckten elektrischen Leitungen, wobei die Leiterplatte im übrigen vorzugsweise aus einem Halbleitermaterial oder Kunststoff besteht. Die Leiterplatte kann ein Substrat sein, auf dem elektrische Leitungen angebracht sind, so dass die Leiterplatte im Wesentlichen ein Schaltungsträger ist. Die Leiterplatte kann beispielsweise zumindest teilweise aus Keramik oder IMS (insulted metal substrate) bestehen. Es ist somit möglich, das Begrenzungselement, d.h. den Spalttopf, sowie den Stator der Nassläuferpumpe einschließlich der dazugehörigen elektrischen Leitungen in einem der Massenfertigung zugänglichen Verfahren besonders einfach herzustellen. Ferner wird durch die erreichte Bauteilereduktion der Montageaufwand für die erfindungsgemäße Nassläuferpumpe reduziert. Insbesondere ist es die Leiterplatte, die den Rotor und den Stator feuchtigkeitsdicht voneinander trennt.The printed circuit board is, in particular, an electrical printed circuit board with printed electrical lines, wherein the printed circuit board, moreover, preferably consists of a semiconductor material or plastic. The printed circuit board may be a substrate, on which electrical lines are mounted, so that the printed circuit board is essentially a circuit carrier. The printed circuit board may, for example, at least partially consist of ceramic or IMS (insulted metal substrate). It is thus possible to use the limiting element, i. the split pot, as well as the stator of the wet runner pump including the associated electrical lines in a mass production accessible method particularly easy to manufacture. Furthermore, the installation effort for the wet-running pump according to the invention is reduced by the achieved component reduction. In particular, it is the circuit board that separates the rotor and the stator moisture-tight from each other.
Vorzugsweise weist das Begrenzungselement und insbesondere die Leiterplatte eine Öffnung zur Aufnahme einer Drehwelle des Pumpenrades auf. Anstelle einer Öffnung kann auch ein Lager für die Drehwelle, beispielsweise durch Kleben, mit der Leiterplatte verbunden sein. Die Leiterplatte kann somit nicht nur zur Stromversorgung des Stators und zur Kühlung des Stators, sondern auch zur Lagerung der Drehwelle des Pumpenrades dienen. Die Öffnung zur Aufnahme der Drehwelle ist insbesondere an der vom Pumpenrad wegweisenden Seite, d.h. zu der Seite, die nicht vom geförderten Fluid angeströmt wird, verschlossen, so dass kein Fluid austreten kann.Preferably, the limiting element and in particular the circuit board has an opening for receiving a rotary shaft of the impeller. Instead of an opening and a bearing for the rotary shaft, for example by gluing, be connected to the circuit board. The printed circuit board can thus not only serve to supply power to the stator and to cool the stator, but also to support the rotary shaft of the impeller. The opening for receiving the rotary shaft is in particular at the pump wheel pioneering side, ie to the side that is not flown by the pumped fluid, closed so that no fluid can escape.

Das Pumpenrad 18 wird von einem zu fördernden Fluid zu einer Drehachse 20 des Pumpenrades 18 in Richtung eines Pfeils 22 über den Einlass 14 axial angeströmt.

Zum Schutz vor äußeren Einflüssen ist das Pumpengehäuse 12 ferner mit einem Pumpendeckel 44 verbunden, so dass zwischen der zum Pumpenrad weisenden Begrenzungsfläche 30 und dem Pumpendeckel 44 ein Trockenbereich 46 ausgebildet ist. Insbesondere wenn sämtliche Statorwicklungen 42 in einer gegebenenfalls mehrschichtigen Leiterplatte 34 angeordnet sind, ist die Leiterplatte 34 bzw. das Begrenzungselement 32 gleichzeitig der Pumpendeckel 44, so dass zusätzlich zu der Leiterplatte 34 bzw. dem Begrenzungselement 32 ein weiterer Pumpendeckel 44 prinzipiell nicht erforderlich ist. Gegebenenfalls kann ein weiterer Pumpendeckel 44 aus Sicherheitsgründen, beispielsweise um eine Beschädigung oder Verschmutzung der Leiterplatte 34 sowie der elektrischen Komponenten der Leiterplatte 34 zu verhindern, vorteilhaft sein.The printed
Im dargestellten Ausführungsbeispiel weist die Leiterplatte 34 eine Buchse 48 auf, welche eine Drehwelle 50 des Pumpenrades 18 aufnimmt und lagert. Das Pumpenrad 18 kann gegebenenfalls zusätzlich an der der Buchse 48 gegenüberliegenden Seite an dem Pumpengehäuse 12 abgestützt bzw. gelagert sein. Gegebenenfalls sind an der Außenseite der Buchse 48 und/oder an der Innenseite des Pumpendeckels 44 weitere Statorwicklungen vorgesehen. Der Pumpendeckel 44 und/ oder das Pumpengehäuse 12 kann zur Verbesserung des magnetischen Kreises auch aus einem magnetisch wirksamen Material bestehen.In the illustrated embodiment, the
Um die Statorwicklungen 42 mit elektrischer Energie zu versorgen, weist die Leiterplatte 34 vorzugsweise einen außerhalb des Pumpengehäuses 12 angeordneten Anschlussbereich 52 auf, in dem Verbindungsmittel, beispielsweise ein Anschlussstecker 54, zur Verbindung mit einer Stromversorgung angeordnet sind. Der Anschlussstecker 54 kann auch innerhalb des Pumpengehäuses 12 und innerhalb des Pumpendeckels 44 angeordnet sein, wobei in diesem Fall die elektrischen Kontakte des Anschlusssteckers 54 direkt auf der Leiterplatte 34 sitzen können und das Pumpengehäuse 12 oder der Pumpendeckel 44 das Gehäuse des Anschlusssteckers 44 bilden können. Die Leiterplatte 34 kann ferner Elektrokomponenten 56 aufweisen, mit deren Hilfe die Nassläuferpumpe 10 gesteuert und geregelt werden kann.In order to supply the
