THERMOELECTRIC MODULE IMPROVEMENT PROGRAM.
Abstract
Open-ended Terms: Thermoelectric generators. Research concerns the improvement of thermoelectric modules over the state of the art as expressed by the 5 KW generator type modules and by competing devices. Since many of the attributes of thermoelectric power conversion are well known, this report attempts primarily to define the problems that require solution before thermoelectric generators can be built with the performance characteristics and reliability required for military applications. Generator analysis and design for a nuclear reactor-thermoelectric, high heat flux system is discussed. A summary of 5 KW generator performance characteristics is as follows: Actual power output 5980 watts gross at a module efficiency of 4.7 per cent. Power output on the basis of best module performance would have been 7570 watts at a module efficiency of 5.7 per cent. Power output on the basis of best thermocouple performance would have been 10,600 watts at 7 per cent efficiency. Life tests on a single couple have exceeded 11,000 hours. Module life was limited to approximately 1000 hours primarily by hot side electrical insulation failure. (Author)
