Abstract
Disclosed is an exhaust gas recovery apparatus of an EGR cooler for a vehicle that circulates some of exhaust gases cooled by an EGR cooler to be discharged, not to an engine but to the outside in a low load operation condition or in a winter season condition, and thus maintaining a temperature of engine cooling water high. The apparatus may include a branch pipe for transferring exhaust gases discharged from the EGR cooler to a turbo charger, a flow rate control valve installed in the branch pipe for adjusting a flow rate of the exhaust gases, and a control unit for controlling an opening degree of the flow rate control valve.
