INTEGRATED FUNCTIONAL HEAT EXCHANGE APPARATUS FOR AUTOMOBILE

摘要

A heat exchange device with combined functions in vehicles includes: a heat exchanger configured to be installed in an exhaust path of an engine and connected to a coolant heat exchanger circuit and an oil heat exchanger circuit; a bypass path configured to be connected to bypass the heat exchanger in the exhaust path; a recirculation path configured to be branched from the exhaust path to be connected to an intake system of the engine; a first control valve configured to control a flow path of exhaust gas between the exhaust path and the bypass path; a second control valve configured to control a flow path of the exhaust gas between the exhaust path and the recirculation path; and a third control valve configured to control the flow path of the exhaust gas between the bypass path and the recirculation path.
