The invention relates to a heat exchanger (10) for thermoelectric generators, comprising at least two channels (12, 14) for a cooling medium (16) and at least one channel (24) for a heating medium (26). The inner region (54) of the at least one channel (24) for the heating medium (26) is provided with ribs (42). According to the invention, said ribs (42) are applied in increasing number in the heating flow direction, contributing, inter alia, to a more efficient use and a homogenisation of the heat flow. |
