Abstract
An integrated exhaust gas recirculation (EGR) cooler with dual coolant loops comprises an exhaust gas inlet and an exhaust gas outlet for recirculating exhaust gas. An exhaust gas flow path extends between the exhaust gas inlet and the exhaust gas outlet to direct recirculating exhaust gas from the exhaust gas inlet to the exhaust gas outlet. A first coolant flow path extends between a first coolant inlet and a first coolant outlet to direct a first coolant flow from the EGR cooler in heat exchange relation with the exhaust gas flow path. A second coolant flow path extends between a second coolant inlet and a second coolant outlet to direct a second coolant flow through the EGR cooler in heat exchange relation with the exhaust gas flow path.
