Abstract

Die Erfindung bezieht sich auf einen Kfz-Abgaskühler (10) mit einer mantelgekühlten Innenkassette (14) zur Kühlung von Abgas eines Verbrennungsmotors mit Hilfe einer Kühlflüssigkeit. Die Innenkassette (14) weist auf:
Einen Innenkassetten-Gehäusekörper (18), der im wesentlichen fünf Seiten umschließt und eine Öffnungsseite aufweist, einen Kassettendeckel (20), der die Öffnungsseite des Gehäusekörpers (18) schließt, und eine umlaufenden Schweißnaht (34), durch die der Randbereich (26) des Kassettendeckels (20) und der öffnungsnahe Randbereich (32) des Gehäusekörpers (18) abdichtend miteinander verbunden sind.
An den beiden Randbereichen (26,32) und proximal der Schweißnaht (34) ist jeweils eine umlaufende Stützschulter (30,28) vorgesehen, wobei sich die beiden Stützschultern (28,30) derart aneinander abstützen, dass radiale Zugkräfte des Kassettendeckels (20) von den Stützschultern (28,30) auf den Gehäusekörper (18) übertragen werden.

The invention relates to a motor vehicle exhaust gas cooler (10) with a jacket-cooled inner cassette (14) for cooling exhaust gas of an internal combustion engine with the aid of a cooling liquid. The inner cassette (14) has:
An inner cassette housing body (18), which encloses substantially five sides and has an opening side, a cassette lid (20) which closes the opening side of the housing body (18), and a peripheral weld (34), through which the edge region (26) the cassette lid (20) and the near-edge edge region (32) of the housing body (18) are sealingly connected to each other.
A circumferential support shoulder (30, 28) is provided at each of the two edge regions (26, 32) and at the proximal end of the weld (34), the two support shoulders (28, 30) being supported on one another such that radial tensile forces of the cassette cover (20) from the support shoulders (28, 30) to the housing body (18).
