摘　　要：通过脉动热管的理论基础及实验,研究了脉动热管的启动特性、准稳态运行特性以及换热工质为含不凝汽的蒸汽时,脉动热管换热器温度的变化规律。同时以传统重力热管换热器的计算为依据,结合脉动热管自身特点,针对工程常见的烟气进行设计计算。通过实验数据分析,确定了脉动热管换热器在实验条件下,设备响应较快,启动性能较好。通过设计计算,提供了脉动热管换热器的结构尺寸。The start-up characteristics,quasi-steady operation characteristics,and the temperature varia-tion regular of pulsating heat pipe heat exchanger when working fluid containing non condensable steam in steam were studied and experimented on.The pulsating heat pipe heat exchanger were designed and cal-culated using flue gas as the working fluid.Pulsating heat pipe heat exchangers with flue gas as working fluid were design and calculation,based on the calculation of traditional gravity heat pipe heat exchangers and combined with the characteristics of pulsating heat pipes themselves.Experimental data by analysis,it is found that under experimental conditions,the pulsating heat pipe heat exchanger has a fast response and good start-up performance.The design dimensions of pulsating heat pipes are provided by design cal-culations.
