摘要 |
The invention relates to a thermoelectric generator unit (1) comprising at least one thermoelectric module (2), which comprises an exhaust gas heat exchanger (3) on one side and a coolant heat exchanger (4) on the opposite side in a sandwich-like arrangement, wherein the exhaust gas heat exchanger and the coolant heat exchanger (3, 4) are designed as flat tubes, the flat sides (9, 13) of which are each connected by means of lateral wall sections (10, 20). According to the invention, side walls (15) are fastened to the lateral wall sections (10, 20) of at least the two heat exchangers (3, 4) lying on the outside, which side walls absorb the clamping forces for an even, permanent compression of the individual elements (2, 3, 4) of the thermoelectric generator unit (1). The thermoelectric module (2) is laterally sealed by means of the side walls (15) that absorb the clamping forces. |
