Abstract

An exhaust heat recovery system includes an exhaust pipe through which exhaust gas exhausted from an engine moves, a heat exchanger mounted in the exhaust pipe and inducing heat exchange between the exhaust gas and a working fluid flowing therein, a plurality of reservoirs supplying working fluids to the heat exchanger, and channel adjusting valves allowing any one of the plurality of reservoirs to be in communication with the heat exchanger.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Patent Application No. 10-2014-0161763 filed on November 19, 2014, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present disclosure relates to an exhaust heat recovery system, and more particularly, to an exhaust heat recovery system that can allow a liquid working fluid to be supplied to a heat exchanger without being stopped. Background technique [0004] Internal combustion engines are widely used in vehicles, ships, small electric motor generators, etc., and attempts have been continuously made to increase the efficiency of the internal combustion engines. In an internal combustion engine, a large amount of heat is generally rejected as exhaust heat, and various systems have been developed for improving the overall efficiency of the internal combustion engine by recovering the exhaust heat...
