Description

Cl Manufacturing process for thermoelectric generator Description A process for making a thermo-electric generator is described. A Thermo-electric Vt generator is made from thermocouples connected in series and parallel. A thermocouple C,1 is a made from two different types of electrically conducting material connected at one end.
SIn our device thermocouples are connected in series and attached to each other with an eC electrically insulating tape, at the ends of the thermocouples. The tape is only at the ends Sto prevent thermal conduction parallel to the electrically conductive thermo-couple C, material.
SThe benefit of the tape method is to make the thermocouples easy to handle and prevent C, short circuits between the ends.
Example Lengths of enamelled Iron wire approximately 200mm long and 50micron in diameter are placed in parallel. Lengths of enamelled Nickel wire approximately 200mm long and 50micron in diameter are placed close to or in parallel to the Iron wire and they are electrically bonded at one end The electrically bonded end is bonded to a electrically insulating tape example kapton which is approximately 10mm wide and 250micron thick.
Enamelled metal means that the metal lengths have an electrically insulating coating on them.
The opposite end of Nickel wire is electrically bonded to lengths of iron wire (6) which are approximately 200mm long and 50micron in diameter and then bonded to electrically insulating tape 2 which is approximatlyl0mm wide and 250micron thick.
The process is repeated thousands of times to produce a tape of thermocouples which can be rolled up or folded for easy handling whilst preventing short circuits of the electrically bonded ends.
Another material could be placed on the side of the metal wire not covered by tape so as to cover the metal thermocouples on both sides with electrically insulating material.
The maximum power point voltage you could expect from 1000 thermocouples connected this way is approximately 3V with a 100°C temperature difference between the two taped ends.
