Abstract

A thermoelectric generator comprising a first conductor element (1) in series with a second conductor element (2), the first conductor element being made of a first electrical conductor material and the second element being made from a second electrically conductive material that is different from to the first electrical conductor element material, joined at their ends via an electrically conductive material, wherein each conductive element is formed as a multifilament array of parallel electrical conductors joined at their ends to form a thermocouple joint (4). A plurality of said thermoelectric generators may be connected in series such that contact is only made between different electrically conductive materials to form thermocouple joints. The thermocouple joints may be connected to each other via electrically insulating tape (3, 5), at the ends of the thermocouples.

Description

Manufacturing process for thermoelectric generator Description
A process for making a thermo-electric generator is described. A Thermo-electric generator is made from thermocouples connected in series and parallel. A thermocouple is a made from two different types of electrically conducting material connected at one end.
In our device thermocouples are connected in series and attached to each other with an electrically insulating tape, at the ends of the thermocouples. The tape is only at the ends to prevent thermal conduction parallel to the electrically conductive thermo-couple material.
The benefit of the tape method is to make the thermocouples easy to handle and prevent short circuits between the ends.
Example
Lengths of enamelled Iron wire (1) approximately 200mm long and SOmicron in diameter are placed in parallel. Lengths of enamelled Nickel wire (2) 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 (4). The electrically bonded end is bonded to a electrically insulating tape (3), 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 (2) is electrically bonded (7) to lengths of iron wire (6) which are approximately 200mm long and SOmicron in diameter and then bonded to electrically insulating tape 2 (5) which is approximatlylOmm 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 (9) 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 approximatery 3 V with a 100°C temperature difference between the two taped ends.
