摘　　要：中国聚变工程实验堆(China Fusion Engineering Test Reactor, CFETR)中心螺线管模型线圈(central solenoid model coil, CSMC)低温测试系统的研制是保证CSMC稳定运行的重要前提。文章以换热器总综合传热数(UA)值、透平功率、压机功率、循环效率和换热器最小换热温差为优化变量,选取透平路分流量、透平出口温度与压力以及节流前的温度为优化目标,对CFETR CSMC低温测试流程中的900 W/4.5 K氦制冷流程进行优化分析。优化后的氦制冷流程循环效率在19%以上,换热器总UA值为37.84 kW/K,总制冷量达到1 kW以上,为CSMC低温测试提供了一定的基础。The development of China Fusion Engineering Test Reactor(CFETR)central solenoid model coil(CSMC)cryogenic test system is an important prerequisite to ensure the stable operation of CSMC.In this paper,the total UA value of heat exchanger,turbine power,compressor power,cycle efficiency and minimum heat exchange temperature difference are used as optimization variables.The turbine mass flow,tubine outlet temperature and pressure,and temperature before throttling are chosen as optimization objectives.The 900 W/4.5 K helium refrigeration process in CFETR CSMC cryogenic test process is optimized.The cycle efficiency of the optimized helium refrigeration process is more than 19%,and the total UA value of heat exchanger is 37.84 kW/K,and the total refrigeration capacity is more than 1 kW,which provides a basis for CSMC cryogenic test.
