摘要: <正> 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

Abstract: An experimental investigation is made on the condensation heat exchanger with spirally corrugated tubes in this paper.The result shows that spirally corrugated tubes can enhance both the convective heat transfer inside tubes and the condensation heat transfer outside tubes. Correlations of convective heat transfer and friction factor inside tubes and condensation heat transfer outside tubes are obtained. The application of spirally corrugated tubes to industry condensation heat exchanger is satisfying.
