Abstract: In this paper，through contrastive experimental method，the fouling resistances of an alternating elliptical axis tube and a copper tube were analyzed and the influence of Songhua River water quality parameters was mainly investigated. The results show that the fouling resistance of cooling water is lower in the former tube than the latter one and it has no obvious induction period. The change of cooling water quality parameters has obvious effect on the fouling，The water quality parameters changed with the time and the relationship between heat transfer enhancement and water quality parameter were thoroughly analyed，which provides a reference for improving the heat transfer efficiency of heat transfer equipments.

摘要： 采用对比的实验方法对交叉缩放椭圆管与光管的污垢热阻进行了分析，并重点研究了冷却水（松花江水）水质参数对污垢产生的影响。实验结果表明：在低流速时，交叉缩放椭圆管的污垢热阻渐近值比光管低，且没有明显的诱导期；实验中冷却水水质参数的变化对污垢影响明显。并深度分析了水质参数随时间的变化及水质参数变化对强化换热表面污垢特性的影响，为换热器提高换热效率提供了参考。
