- This partition 20 extends from the inlet 22 of the exhaust gas cooling module to the outlet 24 of the valve housing 2, which is arranged offset by 90 ° to the inlet 22, so that an exhaust gas flow in the interior of the valve housing 2 is deflected by 90 °.
- the inlet 22 is designed as a flange, via which the module can be flanged directly to an exhaust manifold, not shown, or an engine block.
- the exhaust gas recirculation flaps 12, 14 are arranged on a common shaft 26, which is mounted in the valve housing 2 and is rotatable by means of an electromotive actuator 28 via a coupling linkage 30.

- the fluid connection between the coolant channels 34 of the valve housing 2 and the coolant channel 44 of the heat exchanger 6 is also produced via the flange connection.
- a pressure difference of the cooling circuit of the internal combustion engine is used according to the invention by a coolant inlet 46 is connected in the valve housing 2 with a first connection channel 48, which opens in the vicinity of a coolant inlet 50 of the coolant channel 44 and a coolant outlet 52 is connected from the valve housing 2 via a second connecting channel 54 with a coolant outlet 56 of the coolant channel 44 of the exhaust gas heat exchanger 6.
- the two connection channels 48, 54 are formed separately in the outer housing 4 of the heat exchanger 6 and are arranged opposite to each other with respect to the central axis of the heat exchanger 6.

Description
Die Erfindung betrifft ein Abgaskühlmodul für eine Verbrennungskraftmaschine mit einem Ventil, welches ein Ventilgehäuse, einen im Ventilgehäuse angeordneten Ventilkörper, der einen Abgasrückführkanal beherrscht, und einen Aktuator zur Betätigung des Ventilkörpers aufweist, und einem Abgaswärmetauscher, welcher mit dem Ventilgehäuse verbunden ist, wobei im Ventilgehäuse zumindest ein Kühlmittelkanal ausgebildet ist, der mit einem Kühlmittelkanal des Abgaswärmetauschers fluidisch verbunden ist.The invention relates to an exhaust gas cooling module for an internal combustion engine with a valve having a valve housing, a valve body arranged in the valve body, which dominates an exhaust gas recirculation channel, and an actuator for actuating the valve body, and an exhaust gas heat exchanger, which is connected to the valve housing, wherein in the valve housing at least one coolant channel is formed, which is fluidically connected to a coolant channel of the exhaust gas heat exchanger.
Derartige Abgaskühlmodule sind bekannt. Zur Schadstoffreduzierung wird ein Abgasstrom geregelt einem Abgaskühler zugeführt. Zur Verringerung der Schnittstellen, welche in den vergangenen Jahren über Schlauch-oder Leitungsverbindungen zwischen den einzelnen Aggregaten hergestellt wurden, wurden Module entwickelt, welche über einfache Flanschverbindungen stromführend aneinander befestigt wurden. So wird beispielsweise das Gehäuse eines Abgasrückführventils direkt mit einem Wärmetauscher verbunden. Dies birgt auch den Vorteil, dass ein vor dem Wärmetauscher, also im heißen Bereich der Abgasrückführleitung angeordnetes Abgasrückführventil fluidisch mit dem Kühlmittelmantel des Wärmetauschers verbunden werden kann, um ein Überhitzen des Aktuators durch das heiße Abgas mittels einer thermischen Trennung zu verhindern.Such exhaust gas cooling modules are known. For pollutant reduction, an exhaust gas flow is regulated fed to an exhaust gas cooler. To reduce the interfaces that have been made over the past years via hose or pipe connections between the individual units, modules have been developed, which were attached via simple flange connections to each other in a current-carrying manner. For example, the housing of an exhaust gas recirculation valve is connected directly to a heat exchanger. This also has the advantage that an exhaust gas recirculation valve arranged upstream of the heat exchanger, that is to say in the hot region of the exhaust gas recirculation line, can be fluidically connected to the coolant jacket of the heat exchanger in order to prevent overheating of the actuator by the hot exhaust gas by means of thermal separation.
Ein derartiges Modul ist beispielsweise aus der
Je nach Positionierung des Wärmetauschers und des Ventils in Bezug auf den Kühlmittelkreislauf im Motorraum kann es notwendig sein, sowohl den Kühlmittelzulauf als auch den Kühlmittelablauf am Gehäuse des Wärmetauschers auszubilden. Bei der bekannten Anbindung des Kühlmittelkanals des Ventilgehäuses an den Kühlmittelmantel über den Flansch folgt jedoch eine mangelnde Durchströmung des Kühlmittelkanals im Ventilgehäuse. Der Kühlmittelkanal bildet bei einer derartigen Ausführung einen Totwasserraum.Depending on the positioning of the heat exchanger and the valve with respect to the coolant circuit in the engine compartment, it may be necessary to form both the coolant inlet and the coolant outlet on the housing of the heat exchanger. In the known connection of the coolant channel of the valve housing to the coolant jacket over the flange, however, follows a lack of flow through the coolant channel in the valve housing. The coolant channel forms a dead water chamber in such an embodiment.
Aufgabe der Erfindung ist es daher, ein Durchströmen des mit einem Kühlmittelkanal des Wärmetauschers verbundenen Kühlmittelkanals des Ventilgehäuses auch bei Ausbildung des Kühlmittelzulaufs und des Kühlmittelablaufes am Wärmetauscher sicherzustellen. Dabei soll möglichst auf zusätzliche Bauteile verzichtet werden und es sollen kostengünstige Materialien für das Ventil verwendet werden können.The object of the invention is therefore to ensure a flow through the connected to a coolant passage of the heat exchanger coolant passage of the valve housing even with formation of the coolant inlet and the coolant outlet on the heat exchanger. It should be possible to dispense with additional components and it should cost materials for the valve can be used.
Diese Aufgabe wird durch den kennzeichnenden Teil des Hauptanspruchs gelöst.This object is achieved by the characterizing part of the main claim.
Dadurch, dass der Abgaswärmetauscher einen Kühlmittelzulauf und einen Kühlmittelablauf aufweist, wobei ein Kühlmitteleintritt des Ventilgehäuses über einen ersten Verbindungskanal fluidisch mit dem Kühlmittelzulauf des Abgaswärmetauschers verbunden ist und ein Kühlmittelaustritt des Ventilgehäuses über einen zweiten Verbindungskanal mit dem Kühlmittelablauf verbunden ist, wird das Druckgefälle des Kühlmittelkreislaufs auf den Einlass und Auslass des Ventilgehäuses übertragen und so eine Strömung des Kühlmittels im Kühlmittelkanal des Ventilgehäuses sichergestellt. Durch dieses Sicherstellen der Strömung können kostengünstige Materialien für das Ventil verwendet werden, da mehr Wärme abgeführt wird.Characterized in that the exhaust gas heat exchanger has a coolant inlet and a coolant outlet, wherein a coolant inlet of the valve housing via a first connecting channel fluidly with the coolant inlet the exhaust gas heat exchanger is connected and a coolant outlet of the valve housing is connected via a second connecting channel with the coolant outlet, the pressure drop of the coolant circuit is transmitted to the inlet and outlet of the valve housing, thus ensuring a flow of the coolant in the coolant passage of the valve housing. By ensuring flow, low-cost materials for the valve can be used as more heat is removed.
Vorzugsweise ist der erste Verbindungskanal über den Kühlmittelkanal des Abgaswärmetauschers mit dem Kühlmittelzulauf verbunden, wobei die Mündung des ersten Verbindungskanals in den Kühlmittelkanal näher zum Kühlmittelzulauf angeordnet ist als zum Kühlmittelablauf. Hierdurch bleibt die in den Kühlmittelmantel des Wärmetauschers geführte Kühlmittelmenge regelbar.Preferably, the first connection channel is connected via the coolant channel of the exhaust gas heat exchanger with the coolant inlet, wherein the mouth of the first connection channel is arranged in the coolant channel closer to the coolant inlet than to the coolant outlet. As a result, the amount of coolant guided into the coolant jacket of the heat exchanger remains controllable.
In einer alternativen bevorzugten Ausführung mündet der erste Verbindungskanal im Kühlmittelzulauf des Abgaswärmetauschers. So besteht eine Gleichheit des Temperaturniveaus am Wärmetauscher und am Ventilgehäuse. Es kann die gesamte Druckdifferenz, die über den Wärmetauscher anliegt, auch für die Durchströmung des Ventilgehäuses genutzt werden.In an alternative preferred embodiment, the first connection channel opens in the coolant inlet of the exhaust gas heat exchanger. So there is an equality of the temperature level at the heat exchanger and the valve housing. It can be used for the flow through the valve housing, the entire pressure difference, which rests on the heat exchanger.
In einer weiterführenden Ausführung mündet der zweite Verbindungskanal im Kühlmittelablauf des Abgaswärmetauschers, um eine Wirbelbildung im Kühlmittelmantel durch ein Zuströmen von zwei Seiten und einen hierdurch steigenden Strömungswiderstand zu vermeiden.In a further embodiment, the second connecting channel opens in the coolant outlet of the exhaust gas heat exchanger, in order to avoid vortex formation in the coolant jacket by an inflow of two sides and a flow resistance rising thereby.
Vorteilhafterweise ist die Mündung des ersten Verbindungskanals auf der zum Kühlmittelzulauf und Kühlmittelablauf gegenüberliegenden Seite des Abgaswärmetauschers angeordnet, wodurch Kurzschlussströme zwischen dem Einlass des ersten Verbindungskanals und dem Auslass des zweiten Verbindungskanals vermieden werden und somit eine ausreichende Durchströmung des Kühlmittelkanals im Ventilgehäuse sichergestellt wird.Advantageously, the mouth of the first connection channel is arranged on the side opposite the coolant inlet and coolant outlet side of the exhaust gas heat exchanger, whereby short-circuit currents between the inlet of the first connection channel and the outlet of the second connection channel are avoided and thus a sufficient Flow through the coolant channel is ensured in the valve housing.
Des Weiteren ist es vorteilhaft, den Kühlmitteleintritt des Ventilgehäuses auf der zum Kühlmittelzulauf und Kühlmittelablauf gegenüberliegenden Seite des Abgaswärmetauschers anzuordnen. Hierdurch können bei einem im Gegenstromverfahren betriebenen Abgaswärmetauscher die Verbindungskanäle als gerade Rohre ausgebildet werden.Furthermore, it is advantageous to arrange the coolant inlet of the valve housing on the side opposite the coolant inlet and coolant outlet side of the exhaust gas heat exchanger. As a result, in a flue gas heat exchanger operated in counterflow, the connection channels can be formed as straight tubes.
Um zusätzliche Schnittstellen und Verrohrungen zu vermeiden und somit den Montageaufwand zu verringern sind die Verbindungskanäle in einem Außengehäuse des Abgaswärmetauschers ausgebildet. Ein derartiges Außengehäuse ist insbesondere im Sandguss herstellbar.In order to avoid additional interfaces and piping and thus reduce assembly costs, the connecting channels are formed in an outer casing of the exhaust gas heat exchanger. Such an outer housing can be produced in particular by sand casting.
Vorzugsweise sind der Abgaswärmetauscher mit dem Ventilgehäuse sowie die Verbindungskanäle mit dem Kühlmitteleintritt und dem Kühlmittelaustritt des Ventilgehäuses über einen Flansch unter Zwischenlage einer Dichtung verbunden. So entsteht eine einfache und dichte Art der Anbindung der beiden Kühlmittel führenden Gehäuseteile.Preferably, the exhaust gas heat exchanger with the valve housing and the connecting channels are connected to the coolant inlet and the coolant outlet of the valve housing via a flange with the interposition of a seal. This creates a simple and sealed way of connecting the two coolant-carrying housing parts.
Es wird somit ein Kühlmodul geschaffen, bei welchem auch bei Ausbildung eines Ein- und Auslasses am Außengehäuse des Kühlmoduls eine Durchströmung eines Kühlmittelkanals im angeschlossenen Ventilgehäuse sichergestellt wird. Ein derartiges Modul ist einfach zu montieren und herzustellen. Das Ventil kann direkt in dem Bereich, welcher die höchste thermische Belastung aufweist, zuverlässig gekühlt werden, so dass eine thermische Überlastung des Aktuators vermieden wird. Die Anzahl der vorhandenen Schnittstellen ist minimiert.Thus, a cooling module is created in which a flow through a coolant channel in the connected valve housing is ensured even when an inlet and outlet is formed on the outer housing of the cooling module. Such a module is easy to assemble and manufacture. The valve can be reliably cooled directly in the area which has the highest thermal load, so that a thermal overload of the actuator is avoided. The number of existing interfaces is minimized.

Das dargestellte Abgaskühlmodul besteht aus drei Gehäuseteilen, wovon ein erstes Gehäuseteil ein Ventilgehäuse 2 ist, ein zweites Gehäuseteil ein Außengehäuse 4 eines Abgaswärmetauschers 6 ist und ein drittes Gehäuseteil ein Innengehäuse 8 des Abgaswärmetauschers 6 ist.The illustrated exhaust gas cooling module consists of three housing parts, of which a first housing part is a valve housing 2, a second housing part is an
Das Ventilgehäuse 2 ist das kanalbildende Gehäuse eines Abgasrückführventils 10, welches im vorliegenden Ausführungsbeispiel zwei Abgasrückführklappen 12, 14 als Ventilkörper aufweist, welche jeweils einen Durchströmungsquerschnitt beherrschen, wobei jeder Durchströmungsquerschnitt einem Abgaskanal 16, 18 zugeordnet ist. Der erste Abgaskanal 16 ist vom zweiten Abgaskanal 18 durch eine im Ventilgehäuse 2 ausgebildete Trennwand 20 getrennt. Diese Trennwand 20 erstreckt sich vom Eintritt 22 des Abgaskühlmoduls bis zum Austritt 24 des Ventilgehäuses 2, welcher um 90° versetzt zum Eintritt 22 angeordnet ist, so dass auch ein Abgasstrom im Innern des Ventilgehäuses 2 um 90° umgelenkt wird. Der Eintritt 22 ist als Flansch ausgeführt, über den das Modul direkt an einen nicht dargestellten Abgaskrümmer oder einen Motorblock angeflanscht werden kann.The valve housing 2 is the channel-forming housing of an exhaust
Die Abgasrückführklappen 12, 14 sind auf einer gemeinsamen Welle 26 angeordnet, welche im Ventilgehäuse 2 gelagert und mittels eines elektromotorischen Aktuators 28 über ein Kopplungsgestänge 30 drehbar ist. Die Welle 26 ist außerhalb des Ventilgehäuses 2 von einer Rückstellfeder 32 umgeben, über welche bei Ausfall des Aktuators 28 die Abgasrückführklappen 12, 14 in ihre die beiden Abgaskanäle 16, 18 verschließende Stellung gedreht werden.The exhaust
Im Ventilgehäuse 2 sind zusätzlich Kühlmittelkanäle 34 ausgebildet, über welche das thermisch hochbelastete Ventilgehäuse 2 gekühlt wird und insbesondere der Aktuator 28 vor thermischer Überlastung geschützt wird. Durch diese vorhandenen Kühlmittelkanäle 34 übernimmt das Ventilgehäuse 2 die Funktion eines Vorkühlers. Um trotz der 90° Umlenkung im Abgasweg, also im Bereich der Kanäle 16, 18 eine möglichst lange Kühlstrecke zu erhalten, befinden sich am Ventilgehäuse 2 Kühlmittelrohre 36, die es ermöglichen, dass das Kühlmittel von der Seite des Austritts 24 zur zu den Abgasrückführklappen 12, 14 gegenüberliegenden Seite und wieder zurück zum Austritt 24 strömen kann, ohne eine derartige Umlenkung kostspielig im Ventilgehäuse 2 selbst ausbilden zu müssen. Somit besteht eine thermische Abschirmung zwischen dem Aktuator 28 und den Abgas führenden Kanälen 16, 18 durch die dazwischen angeordneten Kühlkanäle 34. Diese sind so angeordnet, dass neben der Abschirmung auch sichergestellt wird, dass eine möglichst direkte Anbindung der Kühlstrecke an die Abgaskanäle 16, 18 vorhanden ist, um die thermische Belastung dort zu reduzieren, wo sie entsteht.In the valve housing 2 coolant channels 34 are additionally formed, via which the thermally highly stressed valve housing 2 is cooled and in particular the
Das Ventilgehäuse 2 ist über eine Flanschverbindung 38 am Abgaswärmetauscher 6 unter Zwischenlage einer nicht dargestellten Dichtung befestigt. Wie bereits erwähnt, ist im Außengehäuse 4 des Abgaswärmetauschers 6 das Innengehäuse 8 angeordnet, in welchem ebenfalls eine Trennwand 40 ausgebildet ist, welche in Verlängerung der Trennwand 20 des Ventilgehäuses 2 angeordnet ist, so dass eine Trennung der beiden Abgaskanäle 20, 22 auch im Wärmetauscher 6 weiter fortgeführt wird. Das Innengehäuse 8 weist an seinen axialen Enden Erweiterungen 42 auf, deren Außendurchmesser dem Innendurchmesser des Außengehäuses 4 entsprechen, so dass unter Zwischenlage einer Radialdichtung ein einen Kühlmittelkanal 44 bildender Kühlmittelmantel zwischen dem Innengehäuse 8 und dem Außengehäuse 4 dicht abgegrenzt ist.The valve housing 2 is attached via a
Über die Flanschverbindung wird auch die fluidische Verbindung zwischen den Kühlmittelkanälen 34 des Ventilgehäuses 2 und dem Kühlmittelkanal 44 des Wärmetauschers 6 hergestellt.The fluid connection between the coolant channels 34 of the valve housing 2 and the
Damit das Kühlmittel im Ventilgehäuse 2 auch tatsächlich strömt, wird erfindungsgemäß eine Druckdifferenz des Kühlkreislaufs des Verbrennungsmotors genutzt, indem ein Kühlmitteleintritt 46 in das Ventilgehäuse 2 mit einem ersten Verbindungskanal 48 verbunden ist, der in der Nähe eines Kühlmittelzulaufs 50 des Kühlmittelkanals 44 mündet und ein Kühlmittelaustritt 52 aus dem Ventilgehäuse 2 über einen zweiten Verbindungskanal 54 mit einem Kühlmittelablauf 56 des Kühlmittelkanals 44 des Abgaswärmetauschers 6 verbunden ist. Die beiden Verbindungskanäle 48, 54 sind separat im Außengehäuse 4 des Wärmetauschers 6 ausgebildet und sind bezüglich der Mittelachse des Wärmetauschers 6 einander gegenüberliegend angeordnet. Hierdurch werden Kurzschlussströme zwischen den beiden Verbindungskanälen 48, 54 weitgehend verhindert.So that the coolant actually flows in the valve housing 2, a pressure difference of the cooling circuit of the internal combustion engine is used according to the invention by a
Es besteht eine direkte fluidische Verbindung zwischen dem Kühlmittelablauf 56 und den Kühlmittelkanälen 34 des Ventilgehäuses 2 während die fluidische Verbindung zwischen dem Kühlmittelzulauf 50 und den Kühlmittelkanälen 34 über den Kühlmittelmantel 44 hergestellt wird. So können die Verbindungskanäle 48, 54 gerade ausgeführt werden, so dass sie direkt im Sandguss hergestellt werden können und keine zusätzlichen Bauteile verwendet werden müssen.There is a direct fluidic connection between the coolant outlet 56 and the coolant channels 34 of the valve housing 2 while the fluidic connection between the
Das durch den Zulauf 50 in den Kühlmittelmantel 44 einströmende Kühlmittel umströmt das Innengehäuse 8, wobei ein Teil des Kühlmittels durch die entsprechend der Pumpleistung einer angeschlossenen Kühlmittelpumpe anliegenden Druckdifferenz zwischen den beiden Verbindungskanälen 48, 54 aus dem Kühlmittelmantel 44 über eine Mündung 58 in den ersten Verbindungskanal 48 gesaugt wird. Von hier aus strömt das Kühlmittel über den Kühlmitteleintritt 46 in das Ventilgehäuse 2 und durch die Kühlmittelkanäle 34 und die Kühlmittelrohre 36 zum Kühlmittelaustritt 52 und weiter über den Verbindungskanal 54 direkt zum Kühlmittelablauf 56. Zwischen den beiden Verbindungskanälen liegt somit ungefähr das gleiche treibende Druckgefälle an wie zwischen dem Kühlmittelzulauf 50 und dem Kühlmittelablauf 56 des Wärmetauschers 6.The coolant flowing through the
So wird auf einfache Weise ein Durchströmen des Ventilgehäuses 2 mit Kühlmittel sichergestellt. Dies dient dem Schutz des Aktuators 28 vor überhöhter thermischer Belastung und erhöht insgesamt die Kühlleistung des gesamten Moduls.Thus, a flow through the valve housing 2 is ensured with coolant in a simple manner. This serves to protect the
Eine zusätzliche Schadstoffreduzierung durch ein derartiges Modul kann auch dadurch erreicht werden, dass innerhalb des Kühlmittelkanals 44 oder im Zu- oder Ablauf des Kühlmittelkanals 44 ein Kühlmittelventil angeordnet wird, über das der Durchströmungsquerschnitt des Kühlmittelkanals 34, 44 unterbrochen werden kann. Dadurch kann die Warmlaufphase der Verbrennungskraftmaschine, in der die meisten Schadstoffe entstehen, verkürzt werden, da kein Kühlmittel zirkuliert und somit das Abgas weitestgehend ungekühlt zur Verteilerleiste zurückgeführt wird.Additional pollutant reduction by such a module can also be achieved in that within the
Es sollte deutlich sein, dass innerhalb des Schutzbereiches des Hauptanspruchs im Vergleich zum beschriebenen Ausführungsbeispiel verschiedene Modifikationen möglich sind. Insbesondere müssen die Anschlüsse zwischen den Verbindungsleitungen und dem Kühlmittelzulauf und -ablauf nicht genau in der beschriebenen Weise erfolgen. Eine Nutzung des Druckgefälles kann entweder über den Kühlmittelkanal des Wärmetauschers oder direkt über den Zu- und den Ablauf erfolgen. Auch ist die Herstellung und konstruktive Ausgestaltung der Gehäuseteile je nach Anwendung modifizierbar. Als Abgasrückführventil kann beispielsweise auch ein Hubventil verwendet werden. Auch können Bypassventile auf die gleiche Art und Weise gekühlt werden.It should be clear that various modifications are possible within the scope of the main claim in comparison to the described embodiment. In particular, the connections between the connecting lines and the coolant inlet and outlet do not have to be exactly as described. A use of the pressure gradient can be done either via the coolant channel of the heat exchanger or directly via the inlet and the outlet. Also, the production and structural design of the housing parts can be modified depending on the application. As an exhaust gas recirculation valve, for example, a lift valve can be used. Also bypass valves can be cooled in the same way.
