Embodiment Construction

[0054] figure 1 A preferred use of a device 1 of the described type is shown schematically. Shown here is a motor vehicle 29 with an internal combustion engine 3 . Exhaust gas 2 generated in an internal combustion engine 3 , such as an Otto engine or a diesel engine, flows to exhaust gas purification components 27 , 28 .

[0055] The device 1 according to the invention is advantageously arranged directly downstream of the internal combustion engine 3 or in a corresponding exhaust gas purification system. The device can also be provided as part of an exhaust gas recirculation system, wherein an exhaust gas cooler can advantageously be used.

[0056] According to an advantageous embodiment, an oxidation catalytic converter 27 is connected upstream of the device 1 , which can also be at least partially integrated in the device 1 . Downstream of the device 1 it is advantageous to connect the NO x accumulator 28, the NO x The accumulator 28 can likewise be at least partially i...

Abstract

The invention relates to a device (1) for generating electrical energy from exhaust gases (2) of an internal combustion engine (3), comprising a generator (4) having an exhaust gas inlet (5) and an exhaust gas outlet (6 ) and a heat exchange section (7) therebetween, wherein the heat exchange section (7) includes a plurality of flow paths (8) for the exhaust gas (2), the flow paths (8) being at least partially thermoelectrically Surrounded by an element (9), the thermoelectric element (9) is thermally connected to a cooling device (11) on its side (10) facing away from the flow path (8).

Description

technical field [0001] The invention relates to a device for generating electrical energy from the exhaust gases of an internal combustion engine by means of a generator. This relates in particular to generators for converting the thermal energy of the exhaust gases into electrical energy, so-called thermoelectric generators. Background technique [0002] Exhaust gases from the engine of a motor vehicle have thermal energy that is converted into electrical energy by a thermoelectric generator to power a battery or some other energy storage device or to release the necessary energy directly to an electrical consumer. Thereby a greater amount of energy can be used for the operation of the motor vehicle. [0003] Such thermoelectric generators typically include a plurality of thermoelectric converter elements. Thermoelectric materials are of the type capable of efficiently converting thermal energy into electrical energy (Seebeck effect) and converting electrical energy into ...
