Abstract:
Described are the use of induction ovens for producing thermoelectric branches and units for thermoelectric modules, as well as a method for producing thermoelectric semiconductor materials by melting together mixtures of the respective element components of the thermoelectric semiconductor materials or the alloys thereof in an induction oven and pouring the melt thus obtained to form a thermoelectric branch or spraying the melt thus obtained so as to produce a powdery thermoelectric semiconductor material.
Abstract:
The method for producing, processing, sintering, pressing or extruding thermoelectric materials under heat treatment using an inert gas, or at a reduced pressure at temperatures ranging from 100 to 900 °C is characterised in that the producing, processing, sintering, pressing or extruding is carried out in the presence of oxygen scavengers which form thermodynamically stable oxides under the producing, processing, sintering, pressing or extrusion conditions in the presence of free oxygen and thus keep free oxygen away from the thermoelectric material.
Abstract:
In a thermoelectric module comprising a series of p and n type semiconductors con¬ nected in series by conductive contacts, the conductive contacts are in contact with a substrate of moderate to high thermal conductivity that is electrically insulated from the conductive contacts by a resistive surface layer comprising a ceramic material.
Abstract:
The invention relates to a thermoelectric module comprising p and n-conductive thermoelectric material legs mutually connected to each other via electrically conductive contacts, characterized in that the electrically conductive contacts comprise at least one flexibility point on the cold and warm side of the thermoelectric module between the thermoelectric material legs in the course thereof, said point allowing bending and slight displacement of the thermoelectric legs relative to each other.

Abstract:
The thermoelectric module composed of p- and n-conductive thermoelectric material legs which are connected to one another alternately via electrically conductive contacts is characterized in that at least some of the electrically conductive contacts on the cold and/or the warm side of the thermoelectric module are formed between, or embedded into, the thermoelectric material legs composed of porous metallic materials.
Abstract:
Described is a thermoelectric module made from p- and n-conducting thermoelectric material branches that are alternately connected to each other via electrically conducting metal contacts, said electrically conducting metal contacts being connected to the thermoelectric material branches by brazing or high-temperature soldering using solder containing a metal and glass.
