More Information
Summary:A heat exchanger (9), of e.g. an exhaust gas system (5) for an internal combustion engine (1), includes a thermoelectric generator (12) having a hot side (13) and a cold side (14) and including a heating tube (15) on a hot side of a heating device (10), and a cooling tube (16) on a cold side of a cooling device (11). The heating tube and the cooling tube are stacked on one another and form a tube stack (18), with the heating tube and the cooling tube extending parallel to one another in a longitudinal direction (19) of the tube stack. For energy efficiency, a housing (21) of the heat exchanger has a jacket (23) with an integral re-tensioning section (25) that is resiliently adjustable between a relaxed state and a tensioned state. The pre-tensioning section generates a pre-tensioning force (26) pressing the tube stack in a stacking direction (17).
