Abstract
An integrated exhaust gas recirculation (EGR) cooler includes a cooling core allowing an exhaust manifold and an intake manifold to be in communication with each other and an integrated housing having the cooling core inserted thereinto. The integrated housing is provided with a first exhaust port exhausting a coolant introduced thereinto only when a thermo-sensitive device mounted in the integrated housing is operated and a second exhaust port always exhausting the coolant introduced thereinto. An amount of the coolant introduced into an EGR cooler is maximized. Therefore, cooling efficiency may be maximized, and a size of the cooling core may be decreased.
