Thermoelectric modules

Abstract

The present invention relates to thermoelectric modules, in particular for use as thermoelectric generators. A thermoelectric module (300) includes: thermoelectric semiconductor elements (302, 304); printed metal conductors (308) for interconnecting the semiconductor elements; and at least one base support (310) for the printed conductors, the base support including a metal matrix composite.

Description

technical field [0001] The present invention relates to thermoelectric modules, and in particular to thermoelectric modules used as thermoelectric generators. Background technique [0002] The thermoelectric modules (integrated in the corresponding generators) enable power generation while exploiting the temperature drop in the system. [0003] exist figure 1 The principle structure of a known thermoelectric module (TEM) is schematically drawn in . Conductor tracks 102 made of metal are arranged on a ceramic base carrier 100 . These conductor tracks 102 are used for circuit break-up of a plurality of N-type thermoelectric semiconductors 104 or P-type thermoelectric semiconductors 106 . The conductor track 102 can consist of copper, for example. Semiconductor elements or thermocouples 104 can be bordered on both sides by conductor tracks 102 and substrate 100 . [0004] exist figure 2 A known integration of a thermoelectric module as a thermoelectric generator 200 into...

Problems solved by technology

Instead, a specific module is only optimally designed for a certain environment or a certain process and cannot simply be used or matched to other process environments without compromising its reliability and durability

[0007] Due to the high costs and / or correspondingly limited efficiency of developing and adapting to the specific process environment, thermoelectric generators are currently mostly used only in the field of aeronautics and space technology
