Thermoelectric device, thermoelectric apparatus having a multiplicity of thermoelectric devices and motor vehicle having a thermoelectric apparatus

摘要

A thermoelectric device includes at least a first metal foil having a first material thickness, a second metal foil having a second material thickness, an interspace between the first metal foil and the second metal foil, an electrical insulation coating on the first metal foil and the second metal foil towards the interspace and a multiplicity of first semiconductor components and second semiconductor components, which are fixed and electrically connected to one another on the insulation coating in the interspace. A thermoelectric apparatus having a multiplicity of thermoelectric devices and a motor vehicle having a thermoelectric apparatus, are also provided.

主权项

1. A thermoelectric device, comprising:
a first metal foil having a first material thickness, said first material thickness being in a range of from 30 μm to 300 μm; a second metal foil having a second material thickness; said first metal foil and said second metal foil defining an interspace therebetween; electrical insulation coatings disposed on said first metal foil and said second metal foil and facing toward said interspace; said first metal foil having an outer side facing away from said electrical insulating coating and a catalyst carrier layer disposed on said outer side; and a multiplicity of first semiconductor components and second semiconductor components fixed in said interspace on said electrical insulation coatings and said multiplicity of first semiconductor components and second semiconductor components being electrically connected to one another only by brazing material disposed on said insulation coatings.
