Experimental Research on Heat Transfer and Thermoelectric Characteristics of Small Nuclear Power Supply Facilities

针对无人水下航行器(UUV)续航能力差这一缺点,结合核动力UUV中的结合静默式温差发电热管反应堆技术,建立非核电加热实验台架,进行启动实验,验证静默式温差发电热管堆技术的技术可行性。实验结果表明:实验装置系统启动过程顺利,启动后等温性良好;温差发电器件热电性能良好,发电效率可达6.8%。该实验装置作为国内首个基于温差发电及高温热管传热的电加热实验台架,其实验数据可为静默式温差发电热管反应堆进一步设计和应用提供参考。

Aiming at the shorthand of unmanned undersea vehicle (UUV) with poor endurance, combining with the technology of heat pipe reactor with silent thermoelectric conversion, a non-nuclear electric heating experiment platform is established to conduct the start -up experiment. Experiment results show that, the experimental start-up process is smooth, the isothermality is good after the start-up. The thermoelectric performance of the thermoelectric generator is good, with the efficiency of 6.8%. As the first electric heating experiment platform based on thermoelectric power generation and high temperature heat pipe heat transfer, the experimental data could provide a reference for the further design and application of the silent thermoelectric heat pipe reactor.
