【摘要】 本文通过对热管传热热阻的分析和数学变换,将热阻变换为热管某段的一维函数,根据极值定理导出最佳传热比L₁/L₂。由于分析和推导过程的不同,所得结果和文献也不尽相同。在最佳传热比的基础上,根据优化理论,导出了热管换热器加热段和冷却段的优化比。I更多还原

【Abstract】 After an analysis and mathematical conversion of heat transfer thermalresistance of heat pipe, the thermal resistance was converted intoone dimen-sionai function of a section of the heat pipe, and the optimum heat transfer ratio was developed by extremum principle. Results and conclusions differed from Ref. CD and Ref.[2] due to the difference of analysis and deriving process.Based on the optimum heat transfer ratio, by optimization principle, an optimum length ratio of evaporator to condenser of heat pipe heat exchanger was obtained.更多还原
