THERMOELECTRIC GENERATOR MODULE, METAL-CERAMIC SUBSTRATE AND METHOD OF PRODUCING SUCH A METAL-CERAMIC SUBSTRATE

摘要

The invention relates to a thermoelectric generator module with a hot zone and a cold zone including at least a first metal-ceramic substrate, which has a first ceramic layer and at least one structured first metallization applied to the first ceramic layer and is assigned to the hot zone, and at least a second metal-ceramic substrate, which has a second ceramic layer and at least one structured second metallization applied to the second ceramic layer and is assigned to the cold zone, and also a number of thermoelectric generator components located between the first and second structured metallizations of the metal-ceramic substrates. The first metal-ceramic substrate, assigned to the hot zone, has at least one layer of steel or high-grade steel, wherein the first ceramic layer is arranged between the first structured metallization and the at least one layer of steel or high-grade steel. The invention also relates to an associated metal-ceramic substrate and to a method for producing it.
