    摘要： The invention relates to a heat exchanger, comprising at least one first flow channel for conducting a first medium, comprising at least one second flow channel for conducting a second medium, in particular in order to evaporate a liquid working medium as the first medium, and comprising a fluid, such as exhaust gas or charge air, as the second medium, for transmitting heat from the second medium to the first medium. The at least one first flow channel has a first circumferential delimiting wall, and the at least one second flow channel has a second circumferential delimiting wall. The first and the second flow channels are arranged adjacently to each other such that a double wall is formed between the flow-conducting channels by mean of the first and the second delimiting wall.

    摘要： The invention relates to a heat exchanger (20) for an exhaust tract of a motor vehicle, having a housing (2) and having a multiplicity of tubes (3) through which exhaust gas can flow and around which a coolant can flow, wherein the tubes (3) are arranged within the housing (2), and the housing (2) has a coolant inlet (5, 9) and a coolant outlet (6), wherein the exhaust gas and the coolant can flow in a countercurrent configuration with respect to one another through the heat exchanger (20), wherein the internal volume of the housing (2) is divided into a first flow path (22) and a second flow path (21) and the tubes (3) are arranged within the second flow path (21), wherein the first flow path (22) forms a bypass with respect to the second flow path (21), wherein the cross-sectional area (A
    B ) of the first flow path (22) amounts to between 15% and 65%, preferably between 30% and 50%, of the total cross-sectional area (A
    T ), through which the coolant flows, of the housing (2), wherein the total cross-sectional area (A
    T ), through which the coolant flows, of the housing (2) is formed by the cross-sectional area (A
    B ) of the first flow path (22) and the cross-sectional area of the second flow path (21) minus the cross-sectional area occupied by the tubes (3).
