RESEARCH AND DEVELOPMENT ON THERMOCOUPLE ENERGY CONVERTERS (PHASE II)
Abstract
Efforts are being made to develop techniques for fabricating, in quantity, good quality n- and p-type thermoelectric lead telluride cells and to assemble these cells to form 2 thermoelectric devices which will meet the following requirements: (a) each of the 2 thermocouple energy converters will consist of 9 couples and will have an output of 7.5 watts/cubic inch or better at a minimum load current of 20 amp when a temperature gradient of at most 600 K/cm exists across the thermoelectric material; (b) the converters will be capable of operation with the hot side of the thermoelectric material near its melting point (917 C) and the performance indicated should be attainable at a hot side temperature of at least 1000 K; and (c) the devices should be operable for a minimum of one hour. Current effort has resulted in perfecting the casting technique so that n- and p-type cells can be manufactured in quantity. Also, the design and fabrication of the complete cell assembly including a hermetic seal at the cold junction side, having a maximum temperature capability of 780 C, was realized. (Author)
