The present invention relates to an exhaust heat recovery system. The exhaust heat recovery system comprises: an exhaust pipe where exhaust gas discharged from an engine flows; a main flow path where working fluid absorbing heat energy from the exhaust pipe flows; a turbine which is rotated by the working fluid discharged from the main flow path to generate energy; an EGR line which allows a part of the exhaust gas discharged from the engine to circulate to an intake pipe; and a flow control valve which is arranged in the main flow path and controls the flow of the working fluid to exchange the exhaust gas flowing in the EGR line with the working fluid flowing in the main flow path through heat. Therefore, the present invention recovers exhaust heat without a decline in the output of an internal combustion engine as the working fluid is heated through the exhaust gas flowing into the EGR line. |
