20090277489 | Thermoelectric Device - A thermoelectric device is provided which comprises a plurality of elements of a thermoelectric material, which are preferably either all of n-type material or all p-type. In this preferred device, each element has a first end region for exposure to a first temperature, and a second end region for exposure to a second temperature, with the temperature gradient being in the same direction in each of the elements, so each element develops a voltage between its end regions in the same direction. The first end regions of the elements are mounted on a substrate, but the second end regions of the elements are at least substantially free to move with respect to one another. The elements are connected electrically in series, so that the series connection produces a net voltage, the electrical connections being designed to produce only a small amount of heat conduction. | 11-12-2009 |
