Thermoelectric heat exchanger

A thermoelectric heat exchanger for heating or cooling a medium, the thermoelectric heat exchanger comprising:

• at least one first tube configured to carry a first medium;
• at least one second tube configured to carry the first medium, the second tube being arranged substantially parallel to the first tube;
• a casing element that is disposed between the first tube and the second tube, the casing element comprising a first casing part that is connectable to the first tube and at least one second casing part that forms a fluid channel for a second medium;
• and
• a thermoelectric element for heating or cooling the first medium or the second medium, the thermoelectric element being disposed between the first casing part and the second casing part, the thermoelectric element being sealed fluid-tight against the first medium and/or the second medium via the casing element,
• wherein the second casing part has a ribbing that is manufactured from a metallic material, and
• wherein the ribbing has upward bends that are embedded into another material of the second casing part.
