Definitions

  • thermo-electric generator 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • thermocouples 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.

Abstract

La présente invention concerne un générateur thermoélectrique qui comprend un premier élément conducteur (1) raccordé en série à un second élément conducteur (2). Le premier élément conducteur est constitué d'un premier matériau électroconducteur et le second élément conducteur est constitué d'un second matériau électroconducteur différent du premier matériau électroconducteur, lesdits éléments étant reliés à leur extrémité par un matériau électroconducteur. Chaque élément conducteur est formé en un réseau multifilament de conducteurs électriques parallèles reliés à leur extrémité pour former une jonction de thermocouples (4). Plusieurs générateurs thermoélectriques peuvent être raccordés en série de sorte qu'un contact ne s'opère qu'entre différents matériaux électroconducteurs pour former des jonctions de thermocouples. Les jonctions de thermocouples peuvent être reliés les unes aux autres par des rubans de thermocouples isolants (3, 5), aux extrémités de ces derniers.
