Abstract

Official abstract text for this publication.

An exhaust gas recirculation (EGR) cooler for cooling exhaust gas includes at least one channel configured to allow the exhaust gas to flow through it, and a casing defining a cooling chamber around the at least one channel. The cooling chamber is configured to enable heat transfer between the exhaust gas and the coolant. The at least one channel has an interior surface and an exterior surface made of a first metal and a second metal, respectively, and configured to be in contact with the exhaust gas and the coolant, respectively. The second metal has a higher thermal conductivity than the first metal. The casing includes a coolant inlet and a coolant outlet configured to enable the coolant to enter and exit the cooling chamber, and an exhaust gas inlet and an exhaust gas outlet configured to enable the exhaust gas to enter and exit the at least one channel.
