Static energy conversion is a technology without moving mechanical parts to convert heat into electricity. The static energy conversion technology is paid much attention in nucleat power application field for its little maintenance, low vibration, eximious sealability and so on. Today thermoelectric and thermionic converters has been used,but the efficiencies of energy conversion are too low. In order to make the efficiencies competitive with dynamic system many new technologies are studied, involved thermophtovoltaic, alkali metal thermoelectric conversion, thermoacoustic power conversion and magnetohydrodynamics conversion. In this paper the principles and status of these future thchnologies are introduced, and the feasibility for application of each technology is evaluated.%静态能量转换是没有旋转部件的能量转换技术,因其所具有的运行维护少、振动噪声低、系统密封性能好等优点而在核能应用领域一直受到关注.已应用的是热电偶和热离子技术,但转换效率太低.目前出现了多种高效率的静态能量转换技术,包括热光伏、碱金属热电转换、热声转换和磁流体发电等,本文对这些未来的静态能量转换技术的原理和研究状况进行了介绍,并对未来实用化的可能进行了评估.
