The invention discloses a thermal power system suitable for an underwater large-depth navigation device. The thermal power system comprises a fuel gas loop and a Rankine cycle loop; the fuel gas loop comprises a combustion chamber, a fuel gas pipeline, a phase change heat exchanger and a one-way valve which are sequentially connected through fuel gas pipelines; and the Rankine cycle loop comprises a phase change heat exchanger, a turbine, a condenser and a booster pump which are sequentially connected end to end through working medium pipelines. Fuel gas generated by the fuel gas loop in the system only serves as a heat source to participate in operation of the power system, a main engine does not need to be pushed to do work, the exhaust gas treatment problem does not need to be considered, and therefore the system is suitable for adopting various underwater fuels; and the Rankine cycle loop and the external environment are free of material exchange, and the operation efficiency of the turbine is basically irrelevant to the navigation depth, so that the power system has good depth adaptability.
本发明公开了一种适用于水下大深度航行装置的热动力系统,包括燃气回路、朗肯循环回路;燃气回路包括依次通过燃气管道连接的燃烧室、燃气管路、相变热交换器、单向阀;朗肯循环回路包括通过工质管道首尾依次连接的相变热交换器、涡轮机、冷凝器、增压泵;本发明系统中燃气回路所产生的燃气仅作为热源参与动力系统运行,无需推动主机做功,更不用考虑乏气处理问题,因此该系统适合采用多种水下燃料;采用朗肯循环回路与外部环境无物质交换,涡轮机的运行效率基本与航深无关,使本动力系统具有良好的深度适应性。
