Abstract

The present invention relates to an exhaust heat recovery system of a vehicle and a method thereof, wherein an exhaust heat recovery device may include a radiator disposed at a main line and through which hot coolant circulates; an exhaust heat exchanger transferring exhaust heat of an engine to coolant; a first valve selectively circulating the coolant to the main line or a bypass line; a water pump connected to the first valve and circulating the coolant; a coolant temperature sensor detecting temperature of the coolant; a second valve connected to the water pump and disposed at a distributing line to distribute the coolant supplied by the water pump to the engine and the exhaust heat exchanger; and a control portion that controls the first and second valves depending on the temperature of the coolant so as to adjust coolant amount circulating in the engine and the exhaust heat exchanger and coolant amount circulating in the radiator and the bypass line.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2009-0118730 filed in the Korean Intellectual Property Office on December 2, 2009, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The invention relates to an exhaust heat recovery device for vehicles. More particularly, the present invention relates to an exhaust heat recovery device for recovering exhaust heat to reduce fuel consumption, and an exhaust heat recovery method. Background technique [0004] In general, vehicle manufacturers are researching ways to reduce exhaust emissions and fuel consumption. [0005] As catalyst loading increases and Exhaust Gas Recirculation (EGR) cooler capacity becomes larger to accommodate exhaust gas conditioning, vehicle manufacturing costs also increase. [0006] A variable water pump prevents unnecessary cooling, reducing engine warm-up time and ...
