Abstract

The invention relates to a method for producing a thermoelectric element (1) and a thermoelectric element (1). The thermoelectric element has at least one fiber (4) coated with a thermoelectric material (3), wherein the thermoelectric element (1) is annular, the coated fiber (4) extending in the circumferential direction (9) for at least Angular range of 120° (10).

Description

technical field [0001] The invention relates to a method for producing a thermoelectric element and to a thermoelectric element. Background technique [0002] The thermoelectric modules are used individually or in large numbers as thermoelectric generators, which generate electrical energy from the temperature potential and the resulting heat flow. Electric energy is generated based on the so-called Seebeck effect. The thermoelectric module is composed of p-type doped and n-type doped thermoelectric elements electrically connected to each other. A thermoelectric element has a so-called hot side and an oppositely arranged cold side, via which the thermoelectric element is alternately electrically conductively connected to other adjacently arranged thermoelectric elements. In this case, the hot side is thermally connected to the wall of the thermoelectric module to which the heat medium (for example exhaust gas) is applied. Correspondingly, the cold side of the thermoelectr...
