| 内容記述 | Radio Isotope (RI) power generation is useful for deep space explorers. Thermoelectric conversion elements have been used as thermoelectric converter in the U.S. and Russia, known as radioisotope thermoelectric generator (RTG). Thermoelectric conversion elements for general use have been developed in Japan, but there are no examples of their application for RTG. Thermoelectric conversion elements for RTG must be operated on much higher temperature conditions than one for general use. Experiments were conducted to evaluate the conversion efficiency of Si-Ge thermoelectric conversion elements on high temperature condition (over 550 deg). We set a Si-Ge thermoelectric conversion module with a ceramic heater as a heat source instead of RI in our thermal vacuum chamber to imitate space environment. A radiator is equipped at low temperature side of module to dissipate heat. Generated module power was measured and conversion efficiency was calculated by power and heat that passed the module. Increasing the temperature difference between high and low temperature sides of module, both power and conversion efficiency increase. Conversion efficiency is about 0.015 % when temperature difference is 400 deg, that is much smaller than others. One of its reasons is large contact thermal resistances between heater and module and module and radiator. We plan to conduct additional thermal vacuum test after improve it. Besides, we'll conduct thermal design of whole RTG system. | |||||||||||||
