Abstract

Die Erfindung betrifft einen Wärmetauscher, insbesondere zur Abgaskühlung, für einen Verbrennungsmotor eines Kraftfahrzeugs mit zumindest einem ersten Strömungskanal (1) zur Durchströmung mit einem ersten Fluid zur Kühlung eines zweiten Fluids, mit zumindest einem zweiten Strömungskanal (2) zur Durchströmung mit dem zweiten Fluid und zumindest einem dritten Strömungskanal (3) zur Durchströmung mit dem zweiten Fluid, wobei der zumindest eine zweite Strömungskanal (2) und der zumindest eine dritte Strömungskanal (3) durch zumindest ein Trennelement (4) voneinander getrennt sind, mit zumindest einem Gehäuseelement (5) zur Beströmung des zweiten Strömungskanals (2) und/oder des dritten Strömungskanals (3) mit zweitem Fluid, wobei zumindest abschnittsweise zwischen dem Trennelement (4) und dem zumindest einem Gehäuseelement (5) zumindest ein Kanal (6) als Leckageminimierungsdehnungskanal (6) ausgebildet ist, derart, dass der Leckagestrom von zweitem Fluid zwischen dem zumindest einen zweiten und dem zumindest einen dritten Strömungskanal (2, 3) minimiert und Längs- und/oder Querdehnungen des Trennelements (4) und/oder des Gehäuseelements (5) von dem Kanal (6) aufnehmbar sind.
