| 摘要 |
<p>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.</p> |
