Abstract
(A1) Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines thermoelektrischen Bauelementes mit zumindest einem thermoelektrischen Schenkelpaar, das einen n-Schenkel und einen p-Schenkel aufweist, wobei beide Schenkel mit einem elektrisch leitfaehigen Kontaktmaterial verschweisst werden, wobei der n-Schenkel und der p-Schenkel des Schenkelpaares in separaten Schweissschritten mit dem Kontaktmaterial verschweisst werden, sowie ein thermoelektrisches Bauelement.

WO 2009092421 A2 UPAB: 20090811 NOVELTY - The method involves welding an n-leg (2) and a p-leg (3) of a thermoelectric leg pair to an electrically conductive contact material (4) in separate welding steps. Welding parameters for welding of the respective n- and p-legs are adjusted independent of each other, where the legs have contact surfaces at ends in a longitudinal direction. The welding of the n- and p-legs is taken place on the contact surfaces of the respective legs, and the contact material is pressed on the legs by a welding electrode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a thermoelectric component comprising a thermoelectric leg pair. USE - Method for producing a thermoelectric component e.g. thermoelectric generator, peltier element or sensor element (all claimed). ADVANTAGE - The n-leg and p-leg of the thermoelectric leg pair are welded to the electrically conductive contact material in separate welding steps, thus providing the contact between the leg pair and the thermoelectrically conductive contact material in a cost-effective and reliable manner, and producing an efficient thermoelectric component while achieving low contact resistance.
