Zur Reduzierung der Rohemissionen von Brennkraftmaschinen wird ein Teil des erzeugten Abgases in die Zylinder der Brennkraftmaschine zurückgeführt und der Ladeluft zugemischt, hierbei handelt es sich um die sogenannte Abgasrückführung. Dabei erfolgt eine Entnahme des Abgases entweder in einem Hochdruckbereich hinter einem Turbolader oder Abgaskrümmer oder in einem Niederdruckbereich hinter einem Katalysator oder Dieselpartikelfilter. Die Temperatur des entnommenen Abgases variiert demnach etwa zwischen 650° bis 200°C. Mit steigender Abgasentnahme muss das rückgeführte Abgas vor der Zumischung gekühlt werden, die Temperatur des Abgases nach einer Kühlung liegt zwischen 100° bis 180°C. Grundsätzlich werden AGR-Kühler aufgrund der thermischen Belastung durch das heiße Abgas und aufgrund der korrosiven Eigenschaften des Abgases und der damit verbundenen Kondensatbildung aus Edelstahl gefertigt. Aluminium ist ohne entsprechende Kühlung je nach Legierungszusammensetzung oberhalb von etwa 200° bis 280°C nicht mehr formbeständig, das heißt, dass es unter Temperatureinwirkung zur bleibenden Verformung eines Aluminiumkühlers kommen würde.to Reduction of raw emissions of internal combustion engines becomes a part the generated exhaust gas fed back into the cylinders of the internal combustion engine and the charge air admixed, this is the so-called Exhaust gas recirculation. In this case, a removal takes place the exhaust gas either in a high pressure region behind a turbocharger or exhaust manifold or in a low pressure area behind a catalyst or diesel particulate filter. The temperature of the extracted exhaust gas thus varies approximately between 650 ° to 200 ° C. With increasing exhaust gas extraction, the recirculated Flue gas to be cooled before mixing, the temperature of the Exhaust gas after cooling is between 100 ° to 180 ° C. Basically, EGR coolers due to the thermal load of the hot exhaust gas and due to the corrosive properties of the exhaust gas and the so Connected condensate made of stainless steel. aluminum is without appropriate cooling depending on the alloy composition above about 200 ° to 280 ° C no longer dimensionally stable, that means that it remains under the influence of temperature Deformation of an aluminum cooler would come.
Die
Die
Die aufgezeigten Lösungen aus Edelstahl sind material- und montagebedingt relativ teuer, so dass es Bestrebungen gibt, diese Kühler aus anderen Materialien wie Aluminium, Kunststoff oder Mischlösungen herzustellen. Eine immer größere Herausforderung ist auch das Verhältnis von Baugröße zur Kühlleistung aufgrund des immer geringer vorhandenen Bauraums im Motorraum.The shown solutions made of stainless steel are relatively expensive due to material and assembly, so that there are efforts to make these coolers from other materials such as aluminum, plastic or mixed solutions. An ever greater challenge is the ratio of size to cooling capacity due to the ever-smaller space available in the engine compartment.
Ausgehend vom Stand der Technik hat die vorliegende Erfindung daher die Aufgabe, einen Aluminiumkühler sowohl bezüglich der Kühlleistung als auch bezüglich der Baugröße so zu gestalten, dass er variabel und günstig herstellbar und auch im Abgasstrang einsetzbar ist.outgoing The object of the present invention, therefore, an aluminum cooler both in terms of cooling capacity as well as in terms of size too Shaping that he is variable and cheap to produce and can also be used in the exhaust system.
Diese Aufgabe löst die Erfindung mit den Merkmalen des Anspruchs 1. Demnach besteht ein Wärmetauscher aus einem Gehäuse und aus mindestens einem hohlen Kühlprofil, welches in dem Gehäuse angeordnet ist. Kühlprofil und Gehäuse sind aus einem Aluminiumstrangpressprofil hergestellt. In dem Kühlprofil wird ein heißes, zu kühlendes Medium geführt und in dem Gehäuse ein kaltes, kühlendes Medium. Das Kühlprofil verfügt über eine Aufnahmenut und/oder einen Befestigungssteg, über welche das Kühlprofil mit dem Gehäuse oder mit einem anderen Kühlprofil verbunden ist. So wird quasi eine Art System-Kühler geschaffen. Im Strangpressverfahren sind Gehäuse und Kühlprofile beliebiger Größe und Länge günstig herstellbar. Über die Aufnahmenut und den Befestigungssteg können zwei Kühlprofile ineinander geschoben werden, die sich dabei im Verbindungsbereich kalt verfestigen und verdichten. Diese Verbindung ist unterstützt durch den Formschluss so fest, dass kein weiterer Fügevorgang notwendig ist, insbesondere kann ein Lötprozess entfallen. Der Wärmetauscher kann einfach auf verschiedene zu erzielende Kühlleistungen in unterschiedlichen Fahrzeugmodellen angepasst werden, indem jeweils eine bestimmte Menge Kühlprofile miteinander zu einer Kühlmatrix zusammengeschoben werden. An mindestens einem Ende ist die Kühlmatrix dann mit der Innenwand des Gehäuse verbunden. An dem anderen Ende kann die Kühlmatrix in einer besonderen Ausführungsform mit einem Endstück versehen sein, welches nur eine Aufnahmenut und keinen Befestigungssteg aufweist. Im Gehäuse befindet sich mindestens ein Steg, an den ein Kühlprofil oder eine ganze Kühlmatrix angebunden werden kann. Je nach zu erzielender Leistung können auch verschiedene Kühlmatrizen über- oder nebeneinander liegen. Für eine entsprechende Anbindung weist das Gehäuse daher für jede Matrix einen Befestigungssteg auf. Alternativ kann das Gehäuse auch mit Aufnahmenuten anstatt mit Befestigungsstegen ausgestattet sein, in die ein einzelnes Kühlprofil oder eine Kühlmatrix mit jeweils einem Befestigungssteg angekoppelt werden. Bei dieser Ausführungsform besitzen die Endstücke dann jeweils nur einen Befestigungssteg und keine Aufnahmenut. Sowohl Gehäuse als auch Kühlprofile können zur Verbesserung der Leistung eine profilierte oder strukturierte Oberfläche aufweisen. Beispielsweise können in das Kühlprofil Verprägungen eingebracht sein. Das Gehäuse kann in der Außenwand Kühlrippen aufweisen.These Task solves the invention with the features of the claim 1. Accordingly, a heat exchanger consists of a housing and at least one hollow cooling profile, which in the housing is arranged. Cooling profile and housing are made of an extruded aluminum profile. In the cooling profile a hot, to be cooled medium is passed and in the housing a cold, cooling medium. The cooling profile has a receiving groove and / or a fastening web over which the cooling profile with the housing or with another cooling profile connected is. This creates a sort of system cooler. In the extrusion process are housing and cooling profiles of any size and length favorably produced. Over the receiving groove and the fastening bar two cooling profiles can be pushed into each other, which solidify cold in the connection area and compact. This connection is supported by the positive connection so determines that no further joining process is necessary, in particular a soldering process can be omitted. The heat exchanger can easily adapt to different cooling performance be adapted in different vehicle models by each a certain amount of cooling profiles together to form a cooling matrix be pushed together. At least one end has the cooling matrix then connected to the inner wall of the housing. At the other End may be the cooling matrix in a particular embodiment be provided with an end piece, which only one receiving groove and has no fastening web. Located in the housing at least one web to which a cooling profile or a Whole cooling matrix can be connected. Depending on the one to be achieved Power can also be transferred to various cooling matrices. or next to each other. For a suitable connection Therefore, the housing has one for each matrix Fixing bridge on. Alternatively, the housing can also be equipped with receiving grooves instead of with fastening bars, into which a single cooling profile or a cooling matrix be coupled with one attachment bar each. At this Embodiment then have the tails each only one fastening bar and no receiving groove. Both housing as well as cooling profiles can improve the Performance a profiled or textured surface exhibit. For example, in the cooling profile Deformations be introduced. The housing can have in the outer wall cooling fins.
In einer besonderen Ausführungsform ist die Aufnahmenut des Kühlprofils als federnde Aufnahme im Sinne einer Nut und Feder Verbindung ausgestaltet. Dazu ist die Wand der Nut beispielsweise mit einer Unterbrechung versehen, die beim Ineinanderschieben der Kühlprofile von dem Befestigungssteg des anderen Kühlprofils verschlossen wird, so dass kein Medium aus dem Inneren des Kühlprofils austreten kann.In a particular embodiment, the receiving groove of Cooling profiles as a resilient receptacle in the sense of a groove and Designed spring connection. For this purpose, the wall of the groove, for example provided with a break, which when nesting the Cooling profiles of the fastening web of the other cooling profile is closed, so that no medium from the inside of the cooling profile can escape.
Der erfindungsgemäße Wärmetauscher kann auch im relativ heißen Abgasstrang eines Kraftfahrzeugs zur Kühlung eines Abgases einer Brennkraftmaschine eingesetzt werden. Die Aluminiumkühlprofile werden dadurch, dass sie innerhalb des Ge häuses von Kühlmedium umströmt werden, ständig so weit abgekühlt, dass sie trotz der hohen Abgastemperaturen von bis zu 650°C des in den Kühlprofilen geführten Abgases formstabil bleiben. Insbesondere wenn der Kühler als AGR-Kühler eingesetzt wird, ist es sinnvoll, in dem Gehäuse einen kühlmittelfreien Bereich zur Aufnahme eines Bypasskanals vorzusehen. In diesem kühlmittelfreien Bereich wird ein Edelstahlrohr ohne Berührung mit der Gehäusewand so aufgenommen, dass ein luftspaltisolierter Bypass entsteht. Über eine Klappe oder ein Ventil ist es möglich, den Kühler wahlweise anzusteuern oder zu umgehen.Of the inventive heat exchanger can also in the relatively hot exhaust line of a motor vehicle for Used cooling an exhaust gas of an internal combustion engine become. The aluminum cooling profiles are characterized by that flows around within the Ge housing of cooling medium are constantly cooled so far that they despite the high exhaust gas temperatures of up to 650 ° C in the Cooling profiles guided exhaust remain dimensionally stable. In particular, when the radiator is used as an EGR cooler, it makes sense in the case of a coolant-free Provide area for receiving a bypass channel. In this coolant-free Area becomes a stainless steel pipe without touching the housing wall taken so that an air gap isolated bypass is formed. about a flap or a valve makes it possible for the radiator either to control or bypass.
Der erfindungsgemäße Aluminium System Kühler kann aber auch an anderer Stelle im Abgasstrang genutzt werden, um Abgase herunterzukühlen oder beispielsweise die Abgaswärme zur Erwärmung eines Kühlwasserkreislaufs zu nutzen. Grundsätzlich kann der Aluminium System Kühler in fast allen Anwendungsgebieten eines Wärmetauschers eingesetzt werden.Of the Aluminum system cooler according to the invention but can also be used elsewhere in the exhaust system, to cool down exhaust gases or, for example, the exhaust heat to use for heating a cooling water circuit. Basically, the aluminum system cooler used in almost all applications of a heat exchanger become.
