Description

Ladeluftkühler  Intercooler
Die Erfindung betrifft einen Ladeluftkühler für eine Brennkraftmaschine in V-Anordnung mit einer Kühlermatrix, mit einem die Kühlermatrix umgebenden Gehäuse und mit einer vertikalen Zuführung der Ladeluft zur Kühlermatrix. The invention relates to a charge air cooler for an internal combustion engine in a V arrangement with a cooler matrix, with a housing surrounding the cooler matrix and with a vertical supply of the charge air to the cooler matrix.
Aus der DE 10 2011 075 617 Al ist ein Ladeluftkühler für eine Brennkraftmaschine in V- Anordnung bekannt. Angeordnet ist dieser im Zylinder-V, also auf der Oberseite der A charge air cooler for an internal combustion engine in a V arrangement is known from DE 10 2011 075 617 A1. This is arranged in the cylinder V, i.e. on the top of the
Brennkraftmaschine. Die heiße Ladeluft durchströmt in vertikaler Richtung sequentiell zuerst den Ladeluftkühler und danach einen Anschlusskasten. Im Anschlusskasten wiederum wird die gekühlte Ladeluft in einen ersten und zweiten Volumenstrom aufgeteilt, welche einer A-seitigen Zylinderbank und einer B-seitigen Zylinderbank zugeführt werden. Internal combustion engine. In the vertical direction, the hot charge air flows sequentially first through the charge air cooler and then through a connection box. In the plenum box, the cooled charge air is divided into a first and a second volume flow, which are fed to an A-side cylinder bank and a B-side cylinder bank.
In der Praxis hat es sich nun gezeigt, dass sich, aufgrund der Anströmung des Anschlusskastens mit der gekühlten Ladeluft, Kondensat an der kalten Wand des Anschlusskastens niederschlagen und Korrosion bewirken kann.  In practice, it has now been shown that, due to the flow of the cooled charge air in the connection box, condensate can precipitate on the cold wall of the connection box and cause corrosion.
Der Erfindung liegt daher die Aufgabe zugrunde, die thermische Abstimmung des The invention is therefore based on the object, the thermal tuning of
Ladeluftkühlers zu verbessern. Intercooler improve.
Gelöst wird diese Aufgabe durch die Merkmale von Anspruch 1. Die Ausgestaltungen sind in den Unteransprüchen dargestellt. This object is achieved by the features of claim 1. The configurations are shown in the subclaims.
Die Erfindung schlägt also einen Ladeluftkühler vor, bei dem die Kühlermatrix in zwei Blöcke aufgeteilt ist und zwischen den beiden Blöcken eine Gasse ausgebildet ist. Im weiteren Text werden die beiden Blöcke als A-seitiger Block und als B-seitiger Block bezeichnet. Der A- seitige Block dient zur Kühlung der Ladeluft für die A-seitige Zylinderbank und der B-seitige Block dient zur Kühlung der Ladeluft für die B-seitige Zylinderbank. Die Gasse besitzt hierbei eine doppelte Lunktionalität. Zum einen wird die ungekühlte, also heiße, Ladeluft in vertikal Richtung durch die Kühlermatrix geführt und zum anderen werden der A-seitige und der B- seitige Block beabstandet. Innerhalb der Kühlermatrix wird die Ladeluft aus vertikaler Richtung kommend in horizontaler Richtung umgelenkt. Der Austritt der gekühlten Ladeluft erfolgt mittels mehrerer Übertrittfenster in den Seitenwänden des Ladeluftkühlers. In einer Ergänzung sind Schottwände vorgesehen, über welche die Anströmflächen des A-seitigen Blocks und des B-seitigen Blocks vorgebbar sind. The invention therefore proposes a charge air cooler in which the cooler matrix is divided into two blocks and a lane is formed between the two blocks. In the rest of the text, the two blocks are referred to as the A-side block and as the B-side block. The A-side block is used to cool the charge air for the A-side cylinder bank and the B-side block is used to cool the charge air for the B-side cylinder bank. The alley has a double functionality here. On the one hand, the uncooled, ie hot, charge air is guided through the cooler matrix in the vertical direction and, on the other hand, the A-side and B-side block are spaced apart. The charge air is drawn from the vertical direction within the cooler matrix coming redirected in the horizontal direction. The cooled charge air is discharged through several access windows in the side walls of the charge air cooler. In addition, bulkheads are provided, via which the inflow surfaces of the A-side block and the B-side block can be specified.
Indem die Umlenkung der Ladeluft bereits im Ladeluftkühler erfolgt, kann der luftführende Anschlusskasten entfallen. Neben der sich hieraus ergebenden Kostenreduktion ist die Since the charge air is already deflected in the charge air cooler, the air-guiding connection box can be omitted. In addition to the resulting cost reduction, the
Bauhöhenverringerung von Vorteil. Aufgrund des nicht mehr erforderlichen Anschlusskastens verringern sich die Bauteiloberfläche und die Bauteilmasse des Ladeluftpfads, woraus wiederum ein schnelleres Ansprechverhalten bei Änderung der Ladelufttemperatur resultiert. Über die Gasse in der Kühlermatrix kann die ungekühlte, heiße Ladeluft in vertikaler Richtung die Kühlermatrix druckverlustarm durchströmen und sich kontinuierlich auf den A-seitigen und B- seitigen Block verteilen. Durch die Ladeluftführung über die Gasse wird ebenfalls bewirkt, dass nur ungekühlte Ladeluft auf einen oberen Deckel des Ladeluftkühlers trifft, wodurch einer Kondensatbildung wirksam vorgebeugt wird. Reduced overall height is an advantage. Because the connection box is no longer required, the component surface and component mass of the charge air path are reduced, which in turn results in a faster response when the charge air temperature changes. Via the alley in the cooler matrix, the uncooled, hot charge air can flow through the cooler matrix in a vertical direction with little pressure loss and be distributed continuously on the A-side and B-side block. The charge air routing across the alley also ensures that only uncooled charge air hits an upper cover of the charge air cooler, which effectively prevents the formation of condensate.

The cooler matrix 4 comprises an A-side block 9A, a B-side block 9B and an alley 10. The cooler matrix 4 is fastened within the housing 5 via bulkhead walls 11, the base plate 6 and the cover 8.

Im Ladeluftkühler 1 teilt sich die Ladeluft LL in einen ersten Volumenstrom VI und in einen zweiten Volumenstrom V2 auf. Der erste Volumenstrom VI wiederum teilt sich auf in einen A-seitigen ersten Volumenstrom VI A und einen B-seitigen ersten Volumenstrom V1B.

In the charge air cooler 1, the charge air LL is divided into a first volume flow VI and a second volume flow V2. The first volume flow VI in turn is divided into an A-side first volume flow VI A and a B-side first volume flow V1B. The A-side first volume flow VI A flows directly through the A-side block 9A in the vertical direction and is deflected in this in the horizontal direction. The A-side first volume flow VI A is defined via a lower one

Der zweite Volumenstrom V2 durchströmt die Gasse 10. In der Gasse 10 teilt sich der zweite Volumenstrom V2 in zwei Teilvolumina V2A/V2B und einen dritten Volumenstrom V3 auf.
