Exhaust-gas heat exchanger for thermoelectric generator in e.g. motor vehicle, has cooling device attached to thermoelectric module such that device covers surface of module, where surface is turned away to channels of central element

摘要

The exchanger (1) has a thermoelectric module (4), a cooling device (5) e.g. heat deriving plate or liquid-flowed cooling body, and a central element (2) for conveying exhaust gas. The thermoelectric module is arranged on a partial area of radially aligned flow channels (3) of the central element, where the partial area is turned to an exhaust gas carriage. The cooling device is attached laminarly to the thermoelectric module such that the cooling device covers a surface of the thermoelectric module, where the surface is turned away to the flow channels of the central element. An independent claim is also included for a method for manufacturing an exhaust-gas heat exchanger for a thermoelectric generator.
