Abstract

The invention relates to an oil module of a water-cooled internal combustion engine, comprising an oil filter, oil and water channels, a water pump and a thermostatic valve which opens various temperature-dependent water circuits. One water channel starts behind the thermostatic valve in the direction of flow and leads to the suction side of the water pump inside the oil module. The oil module has a housing to which at least one additional functional component is connected. The water channel extends along two sides of the housing which are oriented at an angle in relation to each other, both sides of said channel respectively opening on both sides on at least one sub-section of their length onto the surface of the housing and being closed, respectively by means of a cover to form a channel cross-section that is closed on all sides.

Description

"Ölmodul mit integriertem Kühlwasserkanal""Oil module with integrated cooling water channel"

Die Erfindung betrifft ein Ölmodul nach dem Oberbegriff des Anspruchs 1.The invention relates to an oil module according to the preamble of claim 1.

Derartige Ölmodule sind aus der Praxis bekannt, oder aus der DE 20 2004 018 136 U1 oder der DE 20 2004 011 114 U1. Es handelt sich dabei um integrierte Bauteile, die außer einem Ölfil- ter noch weitere Funktionselemente enthalten. Insbesondere können beispielsweise Funktionselemente vorgesehen sein, die für Wartungsarbeiten zugänglich sein müssen, so dass lediglich an einer konzentrierten Servicestelle ein Zugang freigehalten werden muss und ansonsten beispielsweise im Motorraum eines Kraftfahrzeugs der Bauraum anderweitig genutzt werden kann.Such oil modules are known from practice, or from DE 20 2004 018 136 U1 or DE 20 2004 011 114 U1. These are integrated components that contain, in addition to an oil filter, additional functional elements. In particular, for example, functional elements may be provided, which must be accessible for maintenance, so that only at a concentrated service point access must be kept free and otherwise, for example, in the engine compartment of a motor vehicle, the space can be used elsewhere.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Ölmodul dahingehend zu verbessern, dass dieses eine möglichst Bauraum sparende Anordnung und eine möglichst hohe Funktionssicherheit der Öl- und Wasserführung einer Verbrennungskraftmaschine unterstützt, und dass das Ölmodul möglichst preisgünstig hergestellt werden kann.The invention has for its object to improve a generic oil module to the effect that this as possible space-saving arrangement and the highest possible reliability of the oil and water flow of an internal combustion engine supports, and that the oil module can be produced as inexpensively.

Diese Aufgabe wird durch ein Ölmodul mit den Merkmalen des Anspruchs 1 gelöst. Die Erfindung schlägt mit anderen Worten vor, den so genannten kleinen Kühlkreislauf innerhalb des Ölmoduls zu ermöglichen, also bei nicht ausreichend hoher Wassertemperatur eine Rück- führung des kalten Kühlwassers vom Thermostatventil zur Wasserpumpe. Bei ausreichend hoher Temperatur des Kühlwassers wird hingegen das Thermostatventil umschalten und das Wasser durch den so genannten großen Kühlkreislauf unter Einbeziehung eines Wasserkühlers fließen lassen.This object is achieved by an oil module with the features of claim 1. In other words, the invention proposes to enable the so-called small cooling circuit within the oil module, ie, when the water temperature is not sufficiently high, to return the cold cooling water from the thermostatic valve to the water pump. If the temperature of the cooling water is sufficiently high, on the other hand, the thermostatic valve will switch over and allow the water to flow through the so-called large cooling circuit with the inclusion of a water cooler.

Dadurch, dass der kleine Kühikreislauf in das Ölmodul integriert ist, bedarf es keiner zusätzlichen äußeren Wasserleitungen, so dass einerseits Bauteile wegfallen, wie beispielsweise Rohrleitungen oder Schlauchleitungen und deren jeweilige Anschluss- elemente, wie beispielsweise Schlauchschellen oder dergleichen und so dass Übergangsstellen, wie beispielsweise die Anschlussstellen der Rohrleitungen oder Schlauchleitungen an das Gehäuse des Ölmoduls entfallen und somit potenzielle Fehlerstellen, die gegebenenfalls zu Undichtigkeiten führen könnten, ebenfalls entfallen, wodurch die Funktionssicherheit des Wasserkreislaufs und somit der gesamten Verbrennungskraftmaschine verbessert wird.The fact that the small Kühikreislauf is integrated into the oil module, it requires no additional external water pipes, so on the one hand omitted components, such as pipes or hose lines and their respective connection elements, such as hose clamps or the like and so that crossing points, such as Connection points of the piping or hose lines to the housing of the oil module omitted and thus potential faults, which could possibly lead to leaks, also eliminated, whereby the reliability of the water cycle and thus the entire internal combustion engine is improved.

Vorschlagsgemäß ist ein Wasserkanal des Ölmoduls mit einem offenen Querschnitt vorgesehen, mündet also entlang zumindest einem Teilstück seiner Länge in die Oberfläche des Gehäuses des Ölmoduls. Das Gehäuse, welches diesen Wasserkanal aufweist, ist also an den entprechenden Stellen wie ein offener Kanal und nicht wie ein zirkumferent geschlossenes Rohr ausges- taltet. Dadurch, dass kein ringsum geschlossener Kanal vorgesehen ist, kann Bauraum eingespart und die Fertigung des Gehäuses deutlich vereinfacht werden, da beispielsweise auf entsprechende Kerne im Gießwerkzeug verzichtet werden kann.According to the proposal, a water channel of the oil module is provided with an open cross-section, so flows along at least a portion of its length in the surface of the housing of the oil module. The housing, which has this water channel, is thus at the entprechenden places like an open channel and not designed like a circumferentially closed tube. The fact that no all-round closed channel is provided, space can be saved and the production of the housing can be significantly simplified, since, for example, can be dispensed with corresponding cores in the casting mold.

Weil vorschlagsgemäß der Wasserkanal entlang zweier Seiten des Gehäuses verläuft, lässt sich auf überraschend einfache Weise ein Ölmodul auch dann wirtschaftlich herstellen, wenn es einen komplizierten Verlauf des Wasserkanals aufweist. Ein solch komplizierter Verlauf des Wasserkanals kann beispielsweise dann erforderlich werden, wenn die Lage des Thermostats und der Wasserpumpe aufgrund der Geometrie des zur Verfü- gung stehenden Bauraums zwingend vorgegeben ist und diese beiden Elemente weit voneinander entfernt oder in einem ungünstigen Winkel zueinander ausgerichtet sind.Because, according to proposal, the water channel runs along two sides of the housing, an oil module can be produced economically in a surprisingly simple manner, even if it is has a complicated course of the water channel. Such a complicated course of the water channel may be required, for example, when the position of the thermostat and the water pump is compulsory due to the geometry of the space available and these two elements are far apart or aligned at an unfavorable angle to each other.

Eine besonders hohe Integrationsdichte und damit wiederum ei- ne möglichst geringe erforderliche Bauraumgröße kann vorteilhaft dadurch erzielt werden, dass der offene Kanalabschnitt nicht durch einen einfachen Deckel abgeschlossen wird, sondern durch eine Funktionsbaugruppe, für die ohnehin vorgesehen ist, dass sie an das Gehäuse des Ölmoduls anschließen soll, wie beispielsweise ein Wasserpumpengehäuse, oder ein Wasserpflegegehäuse, in dem beispielsweise ein Kühlwasserfilter oder ein Pflegemittel für das Kühlwasser vorgesehen ist, beispielsweise mit einem auswechselbaren, Inhibitoren aufweisenden Einsatz. Auch wenn das Thermostatventil oder ein Öl- / Wasser- Wärmetauscher innerhalb eines eigenen Gehäuses vorgesehen und an das Gehäuse des Ölmoduls angeschlossen wird, stellt dies eine Funktionsbaugruppe dar, die eben nicht nur eine reine Verschlussfunktion des Gehäuses, wie ein Deckel, aufweist und die daher zum Abschluss des Wasserkanals vorgesehen sein kann.A particularly high integration density and thus again the smallest possible required installation space size can advantageously be achieved by not closing off the open channel section by a simple cover, but rather by a functional subassembly for which provision is made in any case for it to contact the housing of the oil module should connect, such as a water pump housing, or a water care housing, in which, for example, a cooling water filter or a care product is provided for the cooling water, for example, with an exchangeable, inhibitors having use. Even if the thermostatic valve or an oil / water heat exchanger is provided within a separate housing and connected to the housing of the oil module, this represents a functional assembly, just not just a pure closure function of the housing, such as a lid, and therefore may be provided to complete the water channel.

Ein Ausführungsbeispiel der Erfindung wird anhand der rein schematischen Zeichnungen nachfolgend näher erläutert. Dabei zeigen dieAn embodiment of the invention will be explained in more detail below with reference to the purely schematic drawings. The show

Fig. 1 - 3 das Gehäuse eines Ölmoduls, aus drei unterschiedlichen Ansichten.Fig. 1-3 the housing of an oil module, from three different views.

In den drei Figuren ist mit 1 insgesamt ein Gehäuse eines Öl- moduls bezeichnet. Das Gehäuse 1 weist einen Filterraum 2 zurIn the three figures, 1 designates a total of a housing of an oil module. The housing 1 has a filter chamber 2 for

Aufnahme eines Ölfilters auf sowie eine Anschlussfläche 3 für ein nicht montiertes und daher in den Zeichnungen nicht ersieht- liches Wasserpflegemodul und eine Anschlussfläche 4 für eine nicht montierte und daher in den Zeichnungen nicht ersichtliche Wasserpumpe.Receiving an oil filter on and a connection surface 3 for a not assembled and therefore not seen in the drawings Royal water maintenance module and a connection surface 4 for a non-mounted and therefore not visible in the drawings water pump.

Mit 5 ist ein zentraler Pumpen-Einlasskanal gekennzeichnet, welcher in diese Wasserpumpe führt und somit den saugseitigen Anschluss der Wasserpumpe darstellt, während ein schneckenartig verlaufender Pumpen-Auslasskanal mit 6 gekennzeichnet ist, der auf der Druckseite der Wasserpumpe vorgesehen ist.5 is a central pump inlet channel, which leads into this water pump and thus represents the suction-side connection of the water pump, while a helical pump outlet passage is marked with 6, which is provided on the pressure side of the water pump.

Die Anschlussfläche 4 erstreckt sich über den Bereich hinaus, welcher für die Montage der Wasserpumpe vorgesehen ist, wie insbesondere aus den Figuren 2 und 3 ersichtlich ist. Eine in den Fig. 1 bis 3 nicht ersichtliche Funktionsbaugruppe, welche diese Anschlussfläche 4 verschließt, nimmt erstens die erwähnte Wasserpumpe auf, zweitens ein Thermostatventil, sowie drittens einen Anschluss, z. B. in Form eines Anschlussstutzens, über den Kühlwasser von der Verbrennungskraftmaschine in das Gehäuse 1 gelangt.The connection surface 4 extends beyond the region which is provided for mounting the water pump, as can be seen in particular from FIGS. 2 and 3. A not shown in FIGS. 1 to 3 function module which closes this pad 4, firstly receives the aforementioned water pump, secondly a thermostatic valve, and thirdly a connection, for. B. in the form of a connecting piece, passes through the cooling water from the internal combustion engine into the housing 1.

Dabei ist im Gehäuse 1 ein Einlasskanal 7 vorgesehen, der mit einem Einströmkanal 8 in Verbindung steht, nämlich mittels eines aus den Fig. 1 und 3 ersichtlichen Verbindungskanals 9. Durch den Einströmkanal 8 gelangt das Kühlwasser in den saugseitigen, zentralen Pumpen-Einlasskanal 5.In this case, an inlet channel 7 is provided in the housing 1, which is in communication with an inflow channel 8, namely by means of one of Figs. 1 and 3 apparent connection channel 9. Through the inflow 8, the cooling water enters the suction, central pump inlet channel. 5

Wenn das erwähnte Thermostatventil geschlossen ist, das Kühlwasser also durch den sogenannten „kleinen Kühlwasserkreislauf" unmittelbar wieder zu der Saugseite der Wasserpumpe geführt wird, fließt dieses Kühlwasser vom Thermostatventil in den Einlasskanal 7, den Verbindungskanal 9, den Einströmkanal 8 und bis in den Pumpen-Einlasskanal 5 der Wasserpumpe. Der Einlasskanal 7, der Verbindungskanal 9, der Einströmkanal 8 und der Pumpen-Einlasskanal 5 bilden also Abschnitte eines durchgehenden Wasserkanals, der in Strömungsrichtung hinter dem Thermostatventil beginnt und innerhalb des Ölmoduls zur Saugseite der Wasserpumpe führt. In den drei Darstellungen sind jeweils von einem als Wasserfil- terzufluss 10 bezeichneten Kanal die beiden endseitigen Mündungen erkennbar, wobei dieser Wasserfilterzufluss 10 zu einem Kühlmittelfilter oder zu einem Wasserpflegegehäuse führt, welches auch als Kühlmittel-Service-System bezeichnet sein kann, und wobei dieser Wasserfilterzufluss 10 aus dem Pumpen- Auslasskanal 6 gespeist wird.If the mentioned thermostatic valve is closed, the cooling water is thus passed through the so-called "small cooling water circuit" directly to the suction side of the water pump, this cooling water flows from the thermostatic valve in the inlet channel 7, the connecting channel 9, the inflow 8 and into the pump The inlet channel 7, the connecting channel 9, the inflow channel 8 and the pump inlet channel 5 thus form sections of a continuous water channel which starts behind the thermostatic valve in the flow direction and leads to the suction side of the water pump within the oil module. In the three representations, the two end-side openings can be seen in each case by a channel designated as a water filter inlet 10, this water filter inlet 10 leading to a coolant filter or to a water care housing, which may also be referred to as a coolant service system, and this water filter inlet 10 is fed from the pump outlet channel 6.

Ein als Wärmetauscherzufluss 11 bezeichneter Kanal führt dasA designated as heat exchanger inlet 11 channel performs the

Kühlmittel zu einem nicht montierten und daher in den Zeichnungen nicht ersichtlichen Wärmetauscher, welcher an eine aus den drei Darstellungen nicht ersichtliche Anschlussfläche des Gehäuses 1 anschließt. Nach Durchströmung des Wärmetau- schers gelangt das Kühlwasser durch einen als Wärmetauscher- rückfluss 12 bezeichneten Kanal wieder in den Bereich der Funktionsbaugruppe, welche die Anschlussfläche 4 abschließt, so dass dieses Wasser dann beispielsweise zum saugseitigen Eingang 5 der Wasserpumpe geführt werden kann. Coolant to a non-mounted and therefore not apparent in the drawings heat exchanger, which connects to a not apparent from the three representations of the housing surface 1. After flowing through the heat exchanger, the cooling water passes through a channel designated as heat exchanger return flow 12 into the region of the functional module which terminates the connection surface 4, so that this water can then be led, for example, to the suction-side inlet 5 of the water pump.
