引言 螺旋槽管具有轧制方便、传热系数高且抗结垢能力强等优点,因而越来越多地应用于石油、化工、电力等工业部门中.纵观螺旋槽管强化传热的研究发现:螺旋槽管管内强化传热的研究和应用已趋成熟和完善.然而由于实际工作的困难,有关螺旋槽管管外凝结换热的研究尚待深入.为此,本文对螺旋槽管凝结换热器进行了试验研究,并将研究成果应用
Introduction Spiral grooved pipe has the advantages of easy rolling, high heat transfer coefficient and strong anti-fouling ability, so it is increasingly used in petroleum, chemical, electric power and other industrial sectors. It is found that the research and application of enhanced heat transfer in spiral grooved pipe have become mature and perfect.However, due to the difficulty of practical work, the research on the condensation heat transfer outside the spiral grooved pipe still needs further study.Therefore, The heat exchanger was tested and the research results were applied
