摘要： A heat exchanger is provided for heat exchange between a first fluid, in particular a charge air or an exhaust gas, and a second fluid, in particular a coolant, comprising: a block (9) for conducting the first and second fluids separately from each other and for heat exchange, which block (9) has a number of flow channels through which the first fluid can flow; at least one box (3) which is assigned to the block (9) and has a flow connection with the flow channels; and at least one base (1), which is provided with one or more through-openings (7) for leading through the flow channels between the block (9) and the box (3); a flow channel being formed as a flat tube (11) with a narrow tube side (13) and a wide tube side (15), and the through-opening (7) having at least one delimiting contour (19) made to arch away from a plane (23) that is substantially perpendicular to the direction of the tube axis (21) and extends at a distance (25) from said plane. To minimize stresses in the region of the transition from the narrow tube side (13) to the wide tube side (15), the invention provides that a distance value at least at a transition (27) between the narrow tube side (13) and the wide tube side (15) is less than a distance value on the wide tube side (15) in such a way that stresses in the region of the transition (27) are reduced, wherein, at least on the wide tube side (15) and at the transition (27), a change in the distance value is continuous.
