开孔平直(波纹)高效内翅管热交换器的研究开发

摘要

对几种不同结构内翅管的传热和阻力特性进行了实验分析,通过工程实际计算应用比较,揭示了高效内翅管的优越性,提出了采用开孔平直(波纹)内翅管替代原光管作为新一代列管式热交换器的发展方向.%Through analysis by both heat transfer & resistance characteristic experiments of several internal finned-tubes with different structures and comparison between the calculations applied in real projects, this paper discloses the superiority of efficient internal finned-tube and proposes the development of new generation of shell and tube heat exchanger equipped with perforated, straight (corrugated) and internal finned-tubes instead of previous tubes without fins.
