Heating device e.g. air heater, for motor vehicle, has thermoelectric device with leg that with end regions attached at contact section and heat exchanger by layers, where exchanger and wall are made of ceramic having high heat conductivity

摘要

The device has a thermoelectric device with a thermocouple leg (20) in an interspace between a wall and housing. The leg with end regions is attached at a heat contact section of the wall and a heat exchanger (26) by electrically conductive layers. The conductive layers partially interconnect the end regions, and the exchanger and wall are made up of electrically insulated ceramic having aluminum nitride and high heat conductivity.
