Embodiment Construction

[0040] figure 1 A first embodiment of a device 1 according to the invention is shown for generating electrical energy from the exhaust gas of an engine 2 , not shown here. In the lower region, the device 1 has an annular channel which forms an exhaust gas inlet connection 4 . As indicated by the arrows, the entire exhaust gas flows into the generator 3 in a corresponding flow direction 24 . Initially the exhaust gas encounters a catalytic segment 17 , which is realized, for example, with a so-called honeycomb body in which a catalytically active coating is arranged. After passing through the catalytic section 17, the exhaust gas enters the heat exchange section 6, in which the exhaust gas is turned through 90° by means of guide structures arranged in the exhaust gas inlet connection 4 along the radial direction. flow inward. In this case, the exhaust gas is deflected into a plurality of flow paths 9 , whereby a flow distribution device 8 is realized on the housing surface. ...

Description

technical field [0001] The invention relates to a device for generating electrical energy from the exhaust gas of an engine by means of a generator. This refers in particular to generators for converting the thermal energy of the exhaust gas into electrical energy, so-called thermoelectric generators (thermoelectric generators). Background technique [0002] The exhaust gas of a motor vehicle engine contains heat energy which can be converted into electrical energy by means of a thermoelectric generator, for example to fill batteries or other energy stores or to directly supply consumers with the required energy. As a result, energy is available over a large area for the operation of the motor vehicle. [0003] Such thermoelectric generators usually have a plurality of thermoelectric conversion elements. A thermoelectric material is a material that efficiently converts thermal energy into electrical energy (Seebeck effect) and vice versa (Peltier effect). The "Seebeck eff...
