Disclosed is a heat exchanger with combined functions in vehicles, which is capable of reducing costs necessary for constructing equipment, and improving assembly workability by integrating heat exchangers individually installed in an exhaust gas recirculation apparatus, a water-cooling system oil cooler and an exhaust heat recycling system, respectively, into a single package to commonly use relative components. The heat exchanger comprises: a heat exchanger (14) installed in an exhaust route (12) of an engine (10) and connected to an oil heat exchange circuit and a coolant heat exchange circuit; a bypass route (16) connected to the exhaust route (12) to detour the heat exchanger (14); a recirculation route (18) separated from the exhaust route (12) and connected to an intake system of the engine (10); a first control valve (20) for controlling a flow route of the exhaust gas between the exhaust route (12) and the bypass route (16); a second control valve (22) for controlling a flow route of the exhaust gas between the exhaust route (12) and the recirculation route (18); and a third control valve (24) for controlling a flow route of the exhaust gas between the bypass route (16) and the recirculation route (18). |
