Embodiment Construction

[0017]FIG. 1 illustrates one embodiment of a thermoelectric device 20 including a plurality of thermoelectric elements 22 disposed between a cold plate 24 and a hot plate 26. Electrical connections 28 and 30 are provided to allow thermoelectric device 20 to be electrically coupled with an appropriate source of DC electrical power or to allow thermoelectric device 20 to be electrically coupled to one or more devices that use, transform, or store power when thermoelectric device 20 operates as a generator.

[0018]Thermoelectric device 20 may be used as a heater, cooler, electrical power generator, and / or temperature sensor. If thermoelectric device 20 were designed to function as an electrical power generator, electrical connections 28 and 30 would represent the output terminals from such a power generator operating between hot and cold temperature sources.

[0019]FIG. 2 illustrates one embodiment of thermoelectric device 200 capable of operating in high temperatures. This may be an examp...

Abstract

In accordance with one embodiment of the present disclosure, a thermoelectric device includes a plurality of thermoelectric elements that each include a diffusion barrier. The diffusion barrier includes a refractory metal. The thermoelectric device also includes a plurality of conductors coupled to the plurality of thermoelectric elements. The plurality of conductors include aluminum. In addition, the thermoelectric device includes at least one plate coupled to the plurality of thermoelectric elements using a braze. The braze includes aluminum.

Description

GOVERNMENT RIGHTS[0001]A portion or all of this disclosure may have been made with Government support under government contract number TCS-236-36 awarded by the United States Department of Energy, and under government contract number W909MY09C0061 awarded by the United States Army of the United States Department of Defense. The Government may have certain rights in this disclosure.TECHNICAL FIELD[0002]This disclosure relates in general to thermoelectric devices, and more particularly to high temperature thermoelectrics.BACKGROUND OF THE DISCLOSURE[0003]The basic theory and operation of thermoelectric devices has been developed for many years. Presently available thermoelectric devices used for cooling typically include an array of thermocouples which operate in accordance with the Peltier effect. Thermoelectric devices may also be used for heating, power generation and temperature sensing.[0004]Thermoelectric devices may be described as essentially small heat pumps which follow the ...
