为了适应火力发电厂泛气冷凝器及海水淡化冷凝器、预热器强化传热的需要,对螺旋槽管进行了筛选实验,以探求流体阻力较小、传热效果较好的管型,本文介绍了对18种管型筛选的实验情况,对螺旋槽深、槽形、导程及螺纹头数的影响进行了系统地实验比较,提出了1～2种较好的结构形式,但要找出最佳管型,还需进一步作螺旋槽管传热机理的研究。 In order to meet the needs of the plenum condenser and seawater desalination condenser in the thermal power plant and the preheater to enhance the heat transfer, the spiral groove tube was screened to explore the tube with smaller fluid resistance and better heat transfer. In this paper, the experimental conditions of 18 kinds of tubular screening were introduced. The effects of the depth, the groove shape, the lead and the thread number of the spiral groove were systematically experimentally compared and 1 ~ 2 kinds of better structures were proposed. However, The best tube, the need for further study of spiral tube heat transfer mechanism.
