  • Patent number: 9777680
    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.

  • Publication number: 20070261815
    Abstract: A liquid cooled charge air cooler for use with an internal combustion engine comprises a plurality of separator plates supported in parallel spaced relation with one another to define a plurality of pairs of adjacent separator plates. The pairs alternatingly define a first set of adjacent pairs and a second set of adjacent pairs. A charge air inlet and a charge air outlet are each in fluid communication with the first set of adjacent pairs. A coolant inlet and a coolant outlet are each in fluid communication with the second set of adjacent pairs. Fins extend between adjacent separator plates of the first set of adjacent pairs to define a charge air flow path between the charge air inlet and a charge air outlet. A plurality of dams extend between adjacent separator plates of the second set of adjacent pairs in a select offset configuration to define a multi-pass coolant flow path between the coolant inlet and a coolant outlet in heat exchange relation with the charge air flow path.
