| 摘 要： | 针对某一类型烟熏炉换热器进口主流道出口产生局部负压的问题，借助CFD仿真分析手段找出进口主流道结
构缺陷，提出了岔口几何形状的改变结构。分别对这2种不同结构的进口主流道管在Fluent平台上进行内流场分析，对
比两者之间的差异，表明改进后的进口管流速更加均匀，克服了原进口主流道管存在的问题，使得进入各组U型管的蒸
气相对均匀，换热效率得到提高。

| Abstract: | The paper studied structure problem of inlet main pipe of heat exchanger for a certain fumigation oven. i. e. .
its outlet generated local negative pressure, found out its defect by use of CFD simulation way, and put forwards the
improved structure which changed the shape of the branch. Based on Fluent the paper analyzed the internal flow fields of
the pipes for these two different structures. and the results were compared. The results show that flow pressure velocity
inlet pipe is more reasonable and the problem disappears. So the vapor in the different set of U pipes is relatively
uniform. the efficiency of heat exchanger is also improved. |
