    • 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.
    • 它是用于第一流体之间交换热量的热交换器,特别是增压空气或废气,和第二流体,特别是冷却剂,所指出的,包括:一个块(9),以分离和所述第一和第二流体的热交换的指导,这 块(9)包括多个流体通过所述第一流动通道流动; 的至少一个块(9)与所述盒(3),其流动连接与所述流动通道相关联; 和至少一个底部(1),其设有一个或更多个通孔(7),用于在块之间的流动通道的通道(9)和所述盒(3); 其中,在具有管状边缘(13)和管宽侧(15)的扁平管(11)的形式的流动通道中形成,并且其中,所述通道开口(7)从一个向管轴(21)的至少一个垂直的基本上是平面的(23)远 具有弯曲,并在延伸到距离(25),所述平面的边界轮廓(19)。 (17)以最小化在从管窄侧至管宽侧(15),本发明提供的是,过渡区域的应力至少在管边缘(13),并在这样的小于所述管的宽侧面(15)之间的结(27)的距离值 上宽侧配管(15)的距离值是在过渡区(27)的应力减小,至少在管宽侧(15)和过渡(27)的距离值的变化是连续的。
