Abstract

Official abstract text for this publication.

The invention relates to an exhaust gas cooler for an exhaust gas recirculation system, in particular of a motor vehicle, said exhaust gas recirculation system having a total cooling power (P G ) and a total pressure loss coefficient (D G ). The exhaust gas cooler comprises: at least one cooling portion ( 20, 20′ ) which has at least one cooling duct ( 22, 22′ ) and at least one additional duct ( 24, 24′ ); at least one bypass which bypasses at least one of the cooling portions ( 20, 20′ ); and an exhaust gas routing device ( 40 ) which has at least one closing member ( 42 ); wherein the cooling duct ( 22, 22′ ) has a first cooling power (P 1 ) and a first pressure loss coefficient (D 1 ), and the additional duct ( 24, 24′ ) has a second cooling power (P 2 ) and a second pressure loss coefficient (D 2 ). The first cooling power (P 1 ) is greater than the second cooling power (P 2 ), and/or the first pressure loss coefficient (D 1 ) is greater than the second pressure loss coefficient (D 2 ). The closing member ( 42 ) is suitable for at least nearly preventing exhaust gases from flowing through the additional duct ( 24, 24′ ) in order to increase the total cooling power (P G ) and/or the total pressure loss coefficient (D G ).

First claim

Opening claim text (preview).
