    摘要: 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.

    摘要: A heat exchanger including a first flow path for a first working fluid, a second flow path for a second working fluid, a tube at least partially defining one of the first and second flow paths, and a corrugated insert secured to the tube and positioned along the first flow path. A structural deficit is provided at a location on the insert such that structural failures occur at the location in preference to other locations on the insert.

    摘要: A combustion engine system (10) includes a combustion engine (11), a coolant system (46), an exhaust gas recirculation loop (32), and an exhaust gas cooler (34) connected in the loop (32) to transfer heat from the recirculating exhaust gas flow to a coolant flow supplied by the coolant system (46). The exhaust gas cooler (34) includes a plurality of coolant flow passages (66) interleaved with a plurality of recirculating exhaust gas flow passages (68), with the flow passages (66,68) being defined by a stack (60) of nested plates (62,64). Each of the plates (62,64) includes a peripheral flange (72,74) that is nested with the peripheral flange (72,74) of any adjacent nested plate (62,64) to enclose the flow passages (66,68).

    摘要: An exhaust gas recirculation cooler includes an inlet configured to receive exhaust gas from an engine, an outlet configured to direct the exhaust gas back toward the engine, and an exhaust gas flow conduit. The flow conduit includes a first end adjacent the inlet, a second end adjacent the outlet, a first narrow side, a second narrow side, substantially flat broad sides extending between the narrow sides, a first channel adjacent the first narrow side and extending between the ends, a second channel adjacent the second narrow side and extending between the ends, and a plurality of third channels located between the first and second channels and extending between the ends. A plate is located at one end of the flow conduit to inhibit the exhaust gas from flowing through at least one of the first channel and the second channel while allowing exhaust gas flow through the third channels.
