Problems solved by technology

The arrangement of thermoelectric generators comprising thermoelectric elements leads to the problem that, on the one hand, since as much heat as possible from the exhaust gas is required for the production of electrical energy, and therefore a corresponding arrangement of closed connections would be advantageous, on the other hand , the restricted space conditions and the maximum allowable temperature must be considered

Embodiment Construction

[0044] figure 1 The longitudinal section of the heat exchanger 1 is shown. The fluid 5 (or exhaust gas) flows through the inlet 3 in the axial direction 7 and flows into the inner pipe 6 of the heat exchanger 1 through the first end side 8 which is fluidly connected to the inlet 3. Here, the fluid flow is at least partially deflected, so that the fluid 5 then flows in the radial direction 14 in the direction of the first circumferential surface 10 of the inner pipe 6. The fluid 5 passes through the first circumferential surface 10 through the opening 11 and impinges on the heat exchanger tube 12 arranged at the outer side of the first circumferential surface 10. A guide part 13 is arranged between the heat exchanger tubes 12, which guides the fluid 5 around the heat exchanger tube 12. The fluid 5 flowing in the radial direction 14 enters the outflow pipe 15 which surrounds the heat exchanger pipe 12 on the outside and is bounded by the housing 2 on its own outside. Here, the ...

Abstract

The invention relates to a device having a heat exchanger (1) at least comprising a housing (2) having an inlet (3) and an outlet (4) for a fluid (5) and an inner tube (6) having a first end face (8) extending along an axial direction (7) and an opposite second end face (9) and a first circumferential surface (10) having openings (11), further having a plurality of heat exchanger tubes (12) disposed parallel to the axial direction (7) on the outside of the circumferential surface (10), wherein the housing (2) encloses the heat exchanger tubes (12) and the inner tube (6) and the inlet (3) is fluidically connected to the first end face (8), wherein guide elements (13) are disposed between the heat exchanger tubes (12) so that the fluid (5) that enters the inner tube (6) via the first end face (8) flows out across the heat exchanger tubes (12) in the radial direction (14); starting from the inner tube (6). The device is used particularly for constructing a thermoelectric generator for positioning in the underbody of a motor vehicle.

Description

Technical field [0001] The invention relates to a device with a heat exchanger for a thermoelectric generator, in particular for arrangement in the area under the floor of a motor vehicle. Background technique [0002] The exhaust gas from the internal combustion engine of a motor vehicle releases thermal energy, and it is usually desirable to convert the thermal energy into electrical energy by a thermoelectric generator, for example, to charge a battery or some other energy storage device and / or directly supply the required energy to the electricity consumption Device. In this way, more energy is obtained to operate the motor vehicle. By using thermoelectric generators, the energy efficiency of the internal combustion engine is further increased. [0003] Thermoelectric generators of the type described have at least a large number of (modular if appropriate) thermoelectric conversion elements. Thermoelectric materials are materials that can convert thermal energy into electric...
