摘　　要：在单根萘热管传热性能理论和实验研究的基础上,对中温热管换热器内部的温度场和流场进行了研究,选用有效度—传热单元数(ε-NTU)法、离散型计算模型及V-Basic程序,通过多次迭代对中温热管换热器内部的传热和流动进行模拟计算。另外,采用多孔介质模型,利用Fluent软件来近似模拟了热管换热器内部的传热情况,将程序计算结果与模拟所得数值进行了比较和误差分析,并研究了各排热管内外温度的协同作用。Based on the theoretical and experimental research about heat transfer performance of single naphthalene heat pipe,the internal temperature field and flow field of the moderate-temperature heat pipe heat exchanger are studied.By using the efficiency-number of transfer units（e-NTU）,the discrete calculation model and the V-Basic program,the simulation calculation of the moderate-temperature heat pipe heat exchanger is accomplished by advanced iterative algorithm.In addition,a porous media model is used to approximate simulate the temperature field inside the heat exchanger by using Fluent software.The simulation results are compared with the calculation results,and the synergistic effect between the inner and outer temperature of the heat pipe is studied.
