The invention relates to a heat exchanger (1), especially for motor vehicles, which comprises flat pipes (2) through whose interior a first fluid (FL1) flows and that can be impinged upon externally by a second fluid (FL2). The flat pipes (2) are substantially disposed at an angle to the direction of flow (S2) of the second fluid (FL2) and parallel relative one another and are spaced apart so as to configure flow paths for the second fluid (FL2) that extend through the heat exchanger. Cooling ribs (3) are disposed in the flow paths and extend between respective adjacent flat pipes (2). A plurality of wavy ribs (3) are provided as the cooling ribs. These wavy ribs are disposed one behind the other in the direction of flow (S2) of the second fluid (FL2) and are off-set from one another in the direction of flow (S1) of the first fluid (FL1).
A heat exchanger, especially for motor vehicles, having flat tubes (2) through which a first fluid (FL1) can flow and which can be externally exposed to a second fluid (FL2) and which are arranged fundamentally parallel to one another and transversely to the direction of flow (S2) of the second fluid (FL2), and which are spaced apart forming flow paths for the second fluid (FL2) passing through the heat exchanger, cooling fins being arranged in the flow paths, which in each case extend between adjacent flat tubes (2), characterized in that multiple corrugated fins (3), which are arranged in series in the direction of flow (S2) of the second fluid (FL2) and laterally offset in relation to one another, are provided as cooling fins.
