A heat exchanger assembly, in particular an exhaust gas cooler, having a gas inlet pipe attached to an inlet diffuser to improve flow distribution of the gas in a case with a heat exchanger core within. The gas inlet pipe configured to disrupt the momentum of flow of the gas due to at least one bend upstream of the inlet diffuser. The gas inlet pipe including at least two intermediate bends which define multiple section of the gas inlet pipe, at least two of the sections redirecting flow of the gas before an outlet of the gas inlet pipe to more evenly distribute the gas at the outlet of the gas inlet pipe upstream of the inlet diffuser.

A heat exchanger that transfers heat from an exhaust gas flow to a liquid coolant includes a first heat exchange section and a second heat exchange section located adjacent the first heat exchange section. The first heat exchange section is located within a first housing that at least partially encloses a first fluid volume. The second heat exchange section is located within a second housing that at least partially encloses a second fluid volume. A first plurality of heat exchange tubes traverses the first heat exchange section, and a second plurality of heat exchange tubes traverses the second heat exchange section. An exhaust gas flow path of the heat exchanger includes the first fluid volume and the interiors of the second plurality of heat exchange tubes. A coolant flow path of the heat exchanger includes the second fluid volume and the interiors of the first plurality of heat exchange tubes.
