温差发电器及其在航天与核电领域的应用

Thermoelectric Generator and Its Application in Space and Nuclear Fields

概要介绍了温差发电器的基本原理。半导体温差电元件可将放射性同位素的衰变热直接转换成为电能,为月球表面科学试验装置、外层空间探测器等提供电源;也可将反应堆的余热转换为电能,为事故后监测仪表提供可靠的电源保障。

The principle of thermoelectric generator is described. With semiconductor devices, the thermoelectric generator is capable of converting radioactive decay heat to (electricity) to provide power supply for moon investigation apparatus or deep space explorer; the thermoelectric generator is also capable of converting reactor residual heat to electricity to provide reliable power supply for reactor accident monitoring instruments.
