| 摘 要： | 通过对闭式冷却塔内冷却盘管各热阻的数量级分析,认为在实际计算中,管壁导热热阻比其它热阻小一个数量级,计算中可忽略,但其余热阻均不可忽略。影响盘管总热阻大小的因素很多,从数学上分析了各热阻对总热阻的影响,找出影响盘管总热阻的主次因素,为冷却盘管的研究、设计及运行管理提供参考。

| Abstract: | A thermal resistance analysis of the cooling coil for a closed-wet cooling tower was carried out in this paper.It is concluded from the analysis that the tube-wall thermal resistance to heat conduction is relatively small and can be neglected.By comparison,the other thermal resistances must be considered in engineering calculation.There are many factors which have an impact on the total thermal resistance of the coil.The influence of the thermal resistances on the total thermal resistance was analyzed,and the factors influencing the total thermal resistance were classified.The results of the work will give a reference to the research,design and running management of cooling coils. |
