Abstract
The invention relates to a heat exchanger for a motor vehicle, comprising a first flow path (1), a deflection region (13) located downstream of the first flow path (1) and a second flow path (2) that is located downstream of the deflection region (13). The first and second flow paths (1, 2) can be traversed by a fluid to be cooled and can be surrounded by a coolant to dissipate heat. The second flow path (2) has a flow resistance that differs from that of the first flow path (1).
Claims14
A heat exchanger for a motor vehicle, comprising
- a first flow path defined by a first array of separate parallel flow ducts having a rectangular cross section, the plurality of flow ducts in the first array being arranged in a plurality of rows and a plurality of columns,
- a first set of turbulence-generating members provided in the first flow path,
- a deflection region following the first flow path,
- a second flow path following the deflection region defined by a second array of separate parallel flow ducts having a rectangular cross section, the plurality of flow ducts in the second array being arranged in a plurality of rows and a plurality of columns, and
- a second set of turbulence-generating members provided in the second flow path,
- wherein each flow duct in the first array of flow ducts has a same flow resistance and each flow duct in the second array of flow ducts has a same flow resistance, and
- wherein a first depth into which the first set of turbulence-generating members project into the first flow path is less than a second depth into which the second set of turbulence-generating members project into the second flow path such that a flow resistance of the first flow path is lower than a flow resistance of the second flow path.
