Research on thermoelectric conversion module of mW isotope battery
摘要
Abstract
A principle prototype of an mW-level 90Sr radioisotope thermoelectric generator(RTG)was constructed with a customized thermoelectric conversion module.The output performance of the RTG was tested under series and parallel connections of multilayer thermoelectric devices.The re-sults indicate that for the study of multi-layer thermoelectric devices in series and parallel configura-tions,the conversion efficiency reaches its maximum when three layers of thermoelectric conversion devices are connected in series,at which point energy utilization is optimized.The measured maxi-mum conversion efficiency is 1.29%,while the simulated maximum conversion efficiency is 1.54%.The findings are of great significance for the subsequent design of thermoelectric conversion modules and the structural improvement of isotope batteries.关键词
