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 cooler portion (20, 20') which has at least one cooling channel (22, 22') and at least one additional channel (24, 24'); at least one bypass which bridges at least one of the cooler portions (20, 20'); and an exhaust gas conducting device (40) which has at least one closure element (42); wherein the cooling channel (22, 22') has a first cooling power (P1) and a first pressure loss coefficient (D1), and the additional channel (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). The closure element (42) is suitable for at least approximately preventing exhaust gases from flowing through the additional channel (24, 24') in order to increase the total cooling power (PG) and/or the total pressure loss coefficient (DG).
