Patent
Behr GmbH and Co. KG | Date: 2016-12-28

The invention relates to an exhaust gas heat exchanger (1), comprising a pipe bundle (2) having pipes (3) conveying exhaust gas, wherein the pipe bundle (2) is gripped at the intake end and at the discharge end respectively in a base (4, 5), and comprising a housing (7) through which a coolant (6) flows, which housing (7) surrounds the pipe bundle (2), is delimited at the end faces through the two bases (4, 5), and has a coolant inlet (8) and a coolant outlet (9). An extended service life results if in the region of the coolant inlet (8) a flow guiding means (10) is provided, which directs the coolant (6) to locations on the housing (7) at risk of boiling, i.e. to the base on the intake side (4), wherein the at least one flow guiding element (11) forces a change of direction of the coolant flow (6) of approximately 0 < < 90 , in particular from approximately 15 < < 42 .


Patent
Behr GmbH and Co. KG | Date: 2016-02-29

A heat exchanger for a motor vehicle is provided having at least one block formed by tubes arranged parallel to one another and by fins arranged between the tubes. The tubes form multiple first flow ducts through which a first fluid can flow. The regions between the tubes form multiple second flow ducts through which a second fluid can flow around the tubes. The heat exchanger also has a first collecting box with a first fluid port and a second collecting box with a second fluid port. The first flow ducts are in fluid communication with a first cooling circuit via the first fluid port, the second fluid port, and the collecting boxes. The first collecting box or the second collecting box also has a third fluid port that, together with its respective collecting box and further fluid port, are in fluid communication with a second cooling circuit.
