Abstract
A heat exchanger (), of e.g. an exhaust gas system () for an internal combustion engine (), includes a thermoelectric generator () having a hot side () and a cold side () and including a heating tube () on a hot side of a heating device (), and a cooling tube () on a cold side of a cooling device (). The heating tube and the cooling tube are stacked on one another and form a tube stack (), with the heating tube and the cooling tube extending parallel to one another in a longitudinal direction () of the tube stack. For energy efficiency, a housing () of the heat exchanger has a jacket () with an integral re-tensioning section () that is resiliently adjustable between a relaxed state and a tensioned state. The pre-tensioning section generates a pre-tensioning force () pressing the tube stack in a stacking direction ().
