Abstract:
A water-cooled exhaust gas recirculation (EGR) cooler, which receives exhaust gas from an exhaust line, and recirculates cooled exhaust gas to an intake line, includes: a housing having an exhaust gas inlet, into which exhaust gas flows, and an exhaust gas outlet, from which exhaust gas is discharged, and further having a coolant inlet, into which a coolant for cooling the exhaust gas flows, and a coolant outlet, from which the coolant is discharged; tubes, each of which has an enclosed tube shape, arranged inside the housing with a first predetermined interval so that exhaust gas passing from the exhaust gas inlet to the exhaust gas outlet flows inside the tubes; and supporters interposed between the tubes to maintain the first predetermined interval between the tubes and support the tubes, and disposed in a space, in which the coolant flows.
