Abstract
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.
