Abstract
The invention relates to the use of thermo-compression bonding (TCB) for bonding electrically conductive contacts to thermoelectric material pieces, respective processes and thermoelectric modules which are suitable for fitting in the exhaust system of an internal combustion engine.
Claims22
A process for forming a thermo-electric module comprising p- and n-conducting thermoelectric material pieces which are ultimately connected to one another via electrically conductive contacts, the process comprising connecting
- electrically conductive contacts of an electrically conductive contact material being one electrically conductive material cladded on another electrically conductive material to the thermoelectric material pieces by thermo-compression bonding.
A thermoelectric module comprising of p- and n-conducting thermoelectric material pieces which are alternately connected to one another via electrically conductive contacts, wherein the electrically conductive contacts of an electrically conductive contact material being one electrically conductive material cladded on another electrically conductive material are connected to the thermoelectric material pieces by thermo-compression bonding.
