HEAT EXCHANGER FOR A MOTOR VEHICLE

摘要

The invention relates to a heat exchanger for a motor vehicle, comprising an inlet region (14) for supplying and an outlet region (6) for discharging an exhaust gas flow of a heat source, an exchanger region (1) through which the exhaust gas can flow, wherein a coolant can flow around at least one exchanger duct of the exchanger region and, for heat exchange, the exhaust gas flow can flow through said at least one exchanger duct of the exchanger region, a bypass duct (2), wherein the exhaust gas in the bypass duct is in considerably reduced heat exchange with the coolant than the exchanger duct, and an actuating element (5), which is arranged in one of both the inlet region (14) or outlet region (6), for distributing the exhaust gas flow between the bypass duct (2) and the exchanger region (1), wherein the actuating element (5) can be adjusted by means of a thermostat (8) which is in thermal contact with the coolant and has a movable actuating element (9).
