Review on thermoelectric conversion technology for space nuclear power
摘要
Abstract
Space thermoelectric conversion technology is one of the key technologies of space nuclear power.The conversion system covers watt level to megawatt level,which can meet the requirements of space power supply for various space missions.Therefore,it is crucial to develop the space thermoelectric conversion technology.The basic principles and domestic and overseas research progress of the thermoelectric conversion technology for space nuclear power were presented,including thermocouple,thermionics,alkali metal thermal to electric converter(AMTEC),magnetohydrodynamic,thermophotovoltaic,Rankine cycle,Stirling cycle and Brayton cycle.The technical difficulties in space application of various thermoelectric conversion technologies were summarized.Meanwhile,the development direction of thermoelectric conversion technology to realize the basic requirements of long-life and maintenance-free was proposed.Finally,according to the power requirements of different space nuclear power,a leading scheme of thermoelectric conversion technology was put forward.When the power requirement of space nuclear power is less than 100 kWe,it is recommended to use static thermoelectric conversion technologies such as thermocouple conversion and thermionic conversion.When the power requirement exceeds 100 kWe,dynamic thermoelectric conversion technologies such as the Brayton cycle should be used.关键词
