Description
Die Erfindung betrifft eine Kühlvorrichtung, insbesondere Abgaskühlvorrichtung, für eine Verbrennungskraftmaschine mit einer Außenschale, in der zumindest eine Wärmeübertragungseinheit angeordnet ist, die einen Kühlmitteleinlass sowie einen Kühlmittelauslass aufweist und die ein Außengehäuse aufweist, derart, dass ein zwischen der Außenschale und der Wärmeübertragungseinheit ausgebildeter von einem Kühlmittel durchströmter Mantel von einem Kanal getrennt ist, der in der Wärmeübertragungseinheit ausgebildet ist und durch den das zu kühlende Fluid strömt.The The invention relates to a cooling device, in particular Exhaust gas cooler, for one Internal combustion engine with an outer shell, in the at least a heat transfer unit is arranged, which has a coolant inlet and a coolant outlet and having an outer housing, such that one between the outer shell and the heat transfer unit trained by a coolant flowed through Sheath is separated from a duct in the heat transfer unit is formed and flows through the fluid to be cooled.
Derartige Kühlvorrichtungen werden beispielsweise in Verbrennungskraftmaschinen als Abgaskühlvorrichtungen zur Verminderung von Schadstoffemissionen eingesetzt, in denen das Abgas gekühlt mit der frisch angesaugten Luft vermischt und den Zylindern zugeführt wird. Durch diese Temperaturminderung der Zylinderfüllung werden Schadstoffemissionen reduziert.such coolers For example, in internal combustion engines as exhaust gas cooling devices used to reduce pollutant emissions in which the Cooled exhaust gas is mixed with the freshly sucked air and fed to the cylinders. This temperature reduction of the cylinder filling pollutant emissions reduced.

Daher ist es Aufgabe der Erfindung, eine Kühlvorrichtung bereit zu stellen, die die oben genannten Nachteile vermeidet.Therefore It is an object of the invention to provide a cooling device, which avoids the above-mentioned disadvantages.
Diese Aufgabe wird dadurch gelöst, dass zwischen Außenschale und Außengehäuse im unmittelbaren Bereich des Kühlmittelauslasses mindestens ein Leitorgan vorgesehen ist, wobei das mindestens eine Leitorgan sich in Richtung des Mittelpunktes des Kühlmittelauslasses erstreckt.These Task is solved by that between outer shell and outer casing in the immediate Area of the coolant outlet at least one guide element is provided, wherein the at least one Guide organ in the direction of the center of the coolant outlet extends.
Dabei hat es sich als besonders vorteilhaft erwiesen, dass die Leitorgane sternförmig angeordnet sind. Dabei ist es montagetechnisch vom Vorteil, wenn die Leitorgane auf dem Außengehäuse der Wärmeübertragungseinheit angeordnet sind. Eine vollständige Umströmung der Wärmeübertragungseinheit mit dem Kühlmittel, kann dadurch gewährleistet werden, dass zwischen Außenschale und Außengehäuse der Wärmeübertragungseinheit mindestens ein Steg angeordnet ist, der im Mantel einen kühlmitteldurchströmten Kanal begrenzt.there it has proved to be particularly advantageous that the guiding organs star shape are arranged. It is mounting technology of advantage if the guiding elements on the outer casing of the heat transfer unit are arranged. A complete flow around the heat transfer unit with the coolant, can be guaranteed be that between outer shell and outer casing of the Heat transfer unit at least one web is arranged in the jacket a coolant-flow channel limited.
Dabei hat es sich als vorteilhaft erwiesen, dass das mindestens eine Leitorgan als Steg ausgeführt ist oder das mindestens eine Leitorgan durch Leitteilstücke, wie z. B. Stützelemente ausgeführt ist.there It has proved to be advantageous that the at least one guide element designed as a bridge is or at least one guide member by Leitteilstücke, such as z. B. support elements accomplished is.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird nachfolgend beschrieben, hierbei zeigt:One embodiment is shown in the drawing and is described below, this shows:

Es sollte deutlich sein, dass die Leitorgane auch auf einer anderen Weise angeordnet sein können, wie im vorliegenden Ausführungsbeispiel dargestellt. Auch ist die Anzahl der eingesetzten Leitorgane im Wesentlichen abhängig von den einströmenden Randbedingungen des Kühlmittels in den Kühlmittelauslass. In dem vorliegenden Ausführungsbeispiel sind die Leitorgane als durchgehende Stege ausgeführt. Sie können jedoch auch als voneinander beabstandete Leitteilstücke, wie z. B. Stifte ausgeführt werden.It It should be clear that the governing bodies are also on another Can be arranged as in the present embodiment shown. Also, the number of guide elements used in the Essentially dependent from the incoming ones Boundary conditions of the coolant into the coolant outlet. In the present embodiment the guide elements are designed as continuous webs. she can but also as spaced guide sections, such as z. B. pins executed become.
