  • Patent number: 10161292
    Abstract: A cooling system for a vehicle and a control method thereof improves fuel efficiency through quick warm-up of an engine by controlling a flow rate of cooling water passing through an EGR cooler. In the cooling system and control method cooling water with an increased temperature through flow stagnation control is first supplied to an oil heat exchanger side. Heat energy generated from the engine is used to rapidly raise a cooling water temperature and an oil temperature. A warm-up characteristic is improved through the exhaust heat recovery function by heat exchange between exhaust gas and the cooling water in the EGR cooler.
