摘要
放射性同位素衰变释放的能量为MEMS热电动力芯片提供热源,可以制造出微型能源供应单元,从而为MEMS 提供一种理想的高性能、长寿命的微电源。本文通过建立平板形及圆柱形动力芯片的传热模型并求出理论解,分析了RTG- chip同位素热源的尺度及结构对其温度和热电转换效率的影响规律。
Using the released energy during disintegration of radioactive isotope to provide thermal energy, certain miniaturized energy-supplying unit can be fabricated, which would be an ideal micro electrical source with high efficiency and long duration time for MEMS. In this paper, heat transfer models for both plane and cylindrical shape RTG-chip were established and their analytical solutions were obtained. Effects of the size and structure of isotope heat source in RTG-chip on its temperature and thermoelectric conversion efficiency were investigated.
