摘要
在管壳式换热器设计中,通常通过分程来提高换热效率,但在分程布管时,各管程的布管比例,对换热器的换热效率有较大的影响,本文通过推导证明了非均匀布管比均匀布管换热效率高的结论.
The heat-exchanging efficiency is usually improved by the split-range tube distribution in the design of Shell-and-Tube Heat Exchanger.The ratios between each tube range have great influence on the heat-exchanging efficiency of heat exchanger.The result that the heat-exchanging efficiency of non-uniform distributing tube is higher than that of uniform distributing tube is proved by theoretical formula.
