HIGH TEMPERATURE THERMOELECTRIC GENERATOR.
Abstract
A nominal 5-watt laboratory model generator survived a 2556-hr sustained test in a vaccum with a hot junction temperature of 1200 C and a cold junction temperature of 720 C without degradation of power output. Despite an unoptimized design and the use of only p-type thermoelectric material, this generator exhibited a 2.75 watt/lb performance. Tests were performed on high temperature p- and n-type thermoelectric materials to determine their resistance to damage from sublimation and thermal shock. Segmented p- and n-type thermoelements, capable of operating between 1200 C and 500 C in a vacuum, were produced and evaluated for use in an advanced model generator. On the basis of the evaluations made on the segmented thermoelements, a nominal 50-watt advanced experimental model generator was designed, fabricated, and preliminarily tested. (Author)
