THERMOELECTRIC MODULE WITH HEAT EXCHANGER

摘要

A heat exchanger, for an exhaust gas system (5) of an internal combustion engine (1), includes a thermoelectric module (13), converting thermal energy into electrical energy, having a hot side (17) and a cold side (18). A cooling pipe (15), for a cooling fluid, is arranged on the cold side (18) and a heating pipe (16) for a heating fluid, is arranged on the hot side (17). The cooling pipe (15) and the heating pipe (16) are stacked with the thermoelectric module (13) in a stacking direction (19) and form a stack (20). The heat transfer within the stack (20) is improved with at least one of the pipes (15, 16) being curved toward the thermoelectric module (13) at an outer pipe face (26) and with the thermoelectric module (13) curved toward the pipe (15, 16) at an outer module face (27) facing the particular pipe (15, 16).
