  • Exhaust gas cooler for an exhaust gas recirculation system, and an exhaust gas recirculation system with such an exhaust gas cooler
    Patent number: 9103300
    Abstract: 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 (PG) and a total pressure loss coefficient (DG). 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 (P1) and a first pressure loss coefficient (D1), and the additional duct (24, 24?) has a second cooling power (P2) and a second pressure loss coefficient (D2). The first cooling power (P1) is greater than the second cooling power (P2), and/or the first pressure loss coefficient (D1) is greater than the second pressure loss coefficient (D2).
