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.
