Abstract

A thermoelectric temperature-control unit may include a first contact plate, a second contact plate, and at least one plate-shaped thermoelectric transducer. The thermoelectric transducer may have a first transducer side and a second transducer side facing away from the first transducer side. The thermoelectric transducer may be coupled to the first contact plate on the first transducer side and coupled to the second contact plate on the second transducer side. At least one of the first contact plate and the second contact plate may include a coupling zone on a respective inner side. A circumference of the coupling zone may be surrounded by a groove. A heat-conducting material may be arranged in the groove and along the coupling zone, and may directly contact the i) respective inner side and ii) one of the first transducer side and the second transducer side facing the respective inner side.
