用于排气系统的热电发电机和用于热电发电机的接触元件
摘要：
一种热电发电机，包括：具有用于引导热流体的入口和出口的第一流动通道，其入口和出口确定用于热流体的第一流动方向；具有用于引导冷流体的入口和出口的第二流动通道，其入口和出口确定用于冷流体的第二流动方向；多个热电偶被沿第一流动方向彼此相邻地布置在第一流动通道与第二流动通道之间；被布置在多个热电偶与第一流动通道的壁部之间的第一接触元件，第一接触元件具有配属于各个热电偶的接触部段，接触部段提供在分别附属的热电偶与第一流动通道的壁部之间的导热连接；被布置在多个热电偶与第二流动通道的壁部之间的第二接触元件，第二接触元件具有配属于各个热电偶的接触部段，接触部段提供在分别附属的热电偶与第二流动通道的壁部之间的导热连接。第一和第二接触元件的配属于第一热电偶的接触部段的传热热阻的总和大于第一和第二接触元件的配属于第二热电偶的接触部段的传热热阻的总和，第一热电偶沿第一流动方向布置在第二热电偶上游。此外公开了一种用于这种热电发电机的接触元件。
摘要（英）：

A thermoelectric generator includes a first channel for passing a warm fluid along a direction of flow, a second channel for passing a cold fluid, a plurality of thermocouple elements disposed along the direction of flow between the first and second channels, a first member includes portions disposed between the elements and the first channel and associated with the individual elements for providing a heat coupling between the associated element and the first channel, and a second member including portions disposed between the elements and the second channel and associated with the individual elements for providing a heat coupling between the associated element and the second channel. The sum of the thermal resistances of those portions that are associated with a first element positioned upstream of a second element is bigger than the sum of the thermal resistances of those portions that are associated with the second element.
