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.
