管壳式换热器的热阻分析与传热强化

Thermal resistance analysis and beat transfer enforcement of shell-and -tube heat exchanger

本文拟对管壳式换热器传热过程各热阻做数量级估算 ,并用数学理论分析总结传热系数随各热阻的变化规律 。

This article imitate to do number-class estimation to each t hermal resi stance of shell and tube heat exchanger in the procedure of heat transfer and an alyze the chance regular of total coefficient of heat transfer varying with each thermal resistance by mathematical theory ,then point to effectiv way of enfore ment heat transfer.
