EXHAUST HEAT RECOVERY SYSTEM

摘要

The present invention relates to an exhaust heat recovery system. The exhaust heat recovery system comprises: an EGR line to cool exhaust gas discharged from an engine to circulate the cooled exhaust gas to an intake pipe; a turbine to exchange heat with an exhaust pipe to rotate by a vaporized working fluid to generate energy; a super heater arranged on the EGR line to exchange heat with the working fluid flowing to the turbine; and an EGR cooler separated from the super heater and arranged on the EGR line to exchange heat with the exhaust gas flowing to the intake pipe. Since the super heater and the EGR cooler are individually manufactured to be separated from each other, damage by thermal stress is prevented to prevent leakage. Ultimately, the efficiency of the exhaust heat recovery system is increased.
