介绍了螺纹槽管用于船舶冷凝器中的几个问题．在光管冷凝器与螺纹槽管冷凝器对比试验研究的基础上，给出了冷凝器传热、水阻及冷凝特性的试验结果，对螺纹槽管冷凝器的传热性能做了评价．对螺纹槽管的疲劳强度进行了试验及分析，并对螺纹槽管的结垢问题做了论述．所得结果为螺纹槽管开发用于船舶冷凝器提供了依据．
Several problems of thread groove tube used in ship condenser are introduced. Based on the comparative experimental study of light pipe condenser and screw channel pipe condenser, the experimental results of heat transfer, water resistance and condensation of condenser are given, and the heat transfer performance of the grooved pipe condenser is evaluated. The fatigue strength of the thread groove pipe was tested and analyzed, and the scaling problem of the thread groove pipe was discussed. The resulting results provide a basis for the development of threaded groove tubes for use in marine condensers.
