翅片管的应用已有几十年的历史,由于工业的发展,水源的紧张,导致空气冷却器越来越广泛的应用于石油、化工、电力、冶金和原子能等部门。众所周知,任何一种换热器的设计,都需要知道流体的传热和压力降特性,空冷器也不例外。作为翅片管,由于它的复杂的几何特性,目前都是采用实验研究的方法获得管外空气侧的放热和压力降关联式。曾有人 The application of finned tubes has been for decades. Due to industrial development and water shortage, air coolers are increasingly used in petroleum, chemical, power, metallurgy and atomic energy sectors. As we all know, any kind of heat exchanger design, you need to know the fluid heat transfer and pressure drop characteristics, air coolers are no exception. As a finned tube, due to its complex geometric properties, experimental and experimental methods are currently used to obtain the correlation of the exothermic and pressure drop of the air outside the tube.
