摘要：
A heat exchanger, in particular for cooling the exhaust of a motor vehicle internal combustion engine, is disclosed, the heat exchanger comprising a first partial heat exchanger with at least one first flow channel through which a medium to be cooled is to flow and at least one third flow channel through which a first coolant is to flow, at least one second partial heat exchanger with at least one second flow channel through which a medium to be cooled is to flow and at least one fourth flow channel through which a second coolant is to flow, wherein the at least one first flow channel and the at least one second flow channel are fluidly connected, and the at least one first flow channel and the at least one second flow channel have at least one first specific heat transfer surface and at least one second heat transfer surface, wherein second specific heat transfer surface area, divided by first specific heat transfer surface area, yields a quotient (ψ), the at least one first flow channel having a larger quotient (ψ) than second flow channel.
摘要（中）：
公开了一种热交换器，特别是用于冷却机动车辆内燃机的排气的热交换器，该热交换器包括具有至少一个第一流动通道的第一部分热交换器，要冷却的介质通过该第一流动通道至少流动 第一冷却剂流过的第三流动通道，具有至少一个第二流动通道的至少一个第二部分热交换器，要冷却的介质将通过该第二流动通道流动;以及至少一个第四流动通道，第二冷却剂 流动，其中所述至少一个第一流动通道和所述至少一个第二流动通道是流体连接的，并且所述至少一个第一流动通道和所述至少一个第二流动通道具有至少一个第一比热传递表面 至少一个第二传热表面，其中第二比热传递表面积除以第一比热传递表面积，产生商（psi），所述至少一个第一流量ch 具有比第二流动通道更大的商（psi）。
