摘　　要：比较了间壁式传热和分离式热管传热对热侧面积相等的情况下在低温烟气中的的传热,并在同样总面积比的情况下,做多种热管管排组合,通过管排组合改变热管换热器局部的温度分布,总结有利于避免露点腐蚀发生的管排组合规律。Here heat transfer are compared between separating heat pipe and between - wall on the condition of same beat - side area . Also eomparlson are given between a number of heat pipe interbank combination under same total heat transfer heat side and cool side area . Distribution of evaporator section out - side wall are changed by alter heat pipe interbank combination . Then conclusion can be come into being that how to assign interbank combination is propitious to avoid acid dew point corrosion.
