Method for manufacturing a thermoelectric device, particularly intended to generate an electric current in a motor vehicle, and thermoelectric device obtained by such a method

摘要

The invention relates to a method of manufacturing a thermoelectric device comprising a plurality of thermoelectric components (4) for creating an electric current from a temperature gradient applied between two faces (3a, 3b) thereof. In the method, a thermally conductive support (30) is provided in contact with a hot or cold source, a thermally conductive and electrically insulating material is thermally sprayed on the support (30) to produce a coating (21), and an electrically conductive material is thermally sprayed onto the coating (21) to form electric conduction tracks (22) which are intended to receive the thermoelectric components (4) via the faces (3a, 3b) thereof. The invention also relates to a thermoelectric device obtained by the method.
