换热器作为使流体温度达到工艺指标的热量交换器已经被广泛应用,尤其是在节能技术飞速发展的今天换热器的种类也随之越来越多。尤其是在介质条件相对严苛的情况下,结构复杂且制作困难的双管板换热器反而能够达到换热效果最佳的状态。本文将结合工作经验以某台再循环塔底冷却器为例,分析了其双管板换热器的制造要点。 Heat exchangers have been widely used as heat exchangers that make the fluid temperature reach the process index. Especially in the rapid development of energy-saving technologies, the types of heat exchangers are also increasing. Especially in the medium conditions are relatively harsh conditions, the complex structure and the production of double tube heat exchanger but can achieve the best heat exchanger effect. This article will work experience with a recycling tower bottom cooler, for example, analysis of the double-tube heat exchanger manufacturing points.
