一、前言湿式空冷器(喷水蒸发空气冷却器)已得到越来越广泛的应用。为了掌握其工作特点,为设计计算提供依据,我们开展了湿式空冷器管外放热和空气阻力的实验研究。湿式空冷器的管外放热是一种复杂的传热传质过程,其放热规律不同于干式空冷器,有一系列新的特点, First, the preface Wet air cooler (water vapor evaporator air cooler) has been more and more widely used. In order to grasp the characteristics of its work, to provide a basis for the design and calculation, we conducted an experimental study of external air exotherm and air resistance of wet air cooler. Exothermic heat pipe outside the wet air cooler is a complex heat and mass transfer process, its heat release is different from the dry air cooler, there are a series of new features,
