Abstract

A thermoelectric module includes two insulating substrates supporting a plurality of thermoelectric fingers. Each thermoelectric finger has alternating strips of n-type doped material and p-type doped material, wherein adjacent n-type doped strips and p-type doped strips are separated by and electrically coupled to conductive regions. The thermoelectric fingers run in a first direction and are spaced apart from each other. A plurality of holes in the insulating substrates are disposed between adjacent thermoelectric fingers, and area aligned with each other. A length of fabric yarn woven is in and out of substantially aligned holes in each substantially aligned set of holes.

First claim

What is claimed is:

1. A thermoelectric module, comprising:
a first insulating substrate and a second insulating substrate;
a plurality of thermoelectric fingers formed on the first insulating substrate, each thermoelectric finger comprising alternating strips of n-type doped strips and p-type doped strips, wherein adjacent n-type doped strips and p-type doped strips are separated by and electrically coupled to conductive regions, each of the plurality of thermoelectric fingers running in a first direction and spaced apart from each other;
a plurality of holes defined in the first insulating substrate and disposed between adjacent thermoelectric fingers of the plurality of thermoelectric fingers, the plurality of holes including substantially aligned sets of holes, each substantially aligned set of holes including holes that are substantially aligned with each other; and
a length of fabric yarn woven in and out of the holes in each substantially aligned set of holes of the plurality of holes.

2. The thermoelectric module of claim 1 , wherein the holes of each substantially aligned set of holes run in a second direction, and wherein the length of fabric yarn runs in the second direction.

3. The thermoelectric module of claim 2 , wherein the first direction and the second direction are substantially perpendicular.

4. The thermoelectric module of claim 2 , wherein the length of fabric yarn is woven to pass over and under adjacent thermoelectric fingers of the plurality of thermoelectric fingers.

5. The thermoelectric module of claim 1 , wherein the first insulating substrate is a polymer film.

6. The thermoelectric module of claim 1 , wherein the plurality of holes are formed by weaving the length of fabric yarn into the first insulating substrate.

7. The thermoelectric module of claim 1 , wherein at least a first portion of a first of the n-type doped strips extends into a channel defined in a conductive region.

8. The thermoelectric module of claim 7 , wherein the channel is configured such that at least three surfaces of the first portion contact the conductive region.
