Claim:
1. A thermoelectric heat exchanger, comprising two pipes, wherein a first pipe encloses a second pipe, further comprising a thermoelectric material unit which is arranged between the first and the second pipes, wherein a first fluid flows around the first pipe from the outside, while a second fluid flows through the second pipe, wherein the thermoelectric material unit is attached to a conductor profile which connects the first and the second pipes mechanically to one another via the thermoelectric material unit, wherein the conductor profile comprises two parts, wherein a first part of the conductor profile is attached to a second face of the second pipe, while a second part of the conductor profile is attached to a first face of the first pipe, wherein the first and the second parts of the conductor profile are connected to one another via the thermoelectric material unit, wherein a free end of the first part and a free end of the second part project towards one another and are each embodied in an L or T shaped configuration, wherein an electrical insulation is arranged between the first face of the first pipe and the second part of the conductor profile and between the second face of the second pipe and the first part of the conductor profile, wherein two first connecting layers are applied, wherein the at least one of the two first connecting layers is electrically conductive, wherein the first pipe has at least one electrical connection placed in contact with its first connecting layer or the second pipe has at least one electrical connection placed in contact with its first connecting layer, wherein the first pipe and the second pipe are interrupted by at least a predefined distance by a thermomechanical decoupling element configured to allow the first pipe and the second pipe to adapt their relative positions to compensate for stress arising due to thermal expansion between a cold side and a hot side, wherein one of the two first connecting layers is not electrically conductive.
