自湿润流体热管的热输送性能
Heat-transport capability of self-rewetting fluid heat pipe
摘要
Abstract
Dilute aqueous solutions of alcohols with large number of carbon atoms,due to their properties associated to an anomalous dependency of the surface tension with temperature,can be prepared as self-rewetting fluids. In this study,experimental investigation was conducted to explore heat transport capability of heat pipe working with self-rewetting fluid [0.1% (mass) heptanol aqueous solution]. Under different heat loads and different orientations (vertical and horizontal orientation),the heat transport capabilities of heat pipe with the self-rewetting fluid and water were compared. The results show that with the increase of heating power,the heat transport capability of heat pipe is enhanced by using the self-rewetting fluid. In the horizontal heating mode,without the influence of gravity,the enhancement of heat transfer is more evident. Compared with water,the self-rewetting fluid presents significantly better heat transport capability.关键词
