1 引言 随着对传热过程这一客观规律认识的深化以及加工制造技术的进步,人们已能研制开发出各式各样的强化换热元件,并在工程实践中取代传统的光滑管从而取得省材节能的双重效果。T.C.Canavos曾预言:到目前为止,强化换热元件的工作还仅仅是个开始,但是它的好处是那样地明显,以至于普通光滑管之被淘汰只不过是一个时间的问题了。多年来的实践证明这种预言是正确的,在强化换热元件中,强化液体泡核沸腾的元件的研究进展尤为突出,自60年代末期以后,先后有4种管型实现商品化,其中一种就是T形翅片管（Gewa-T）。T形翅片管自1978年问世于原联邦德国的Wieland Worke公司以后,国内外已有多项研
1 Introduction With the deepening of the understanding of the objective laws of heat transfer process and the progress of manufacturing technology, people have been able to develop a wide range of enhanced heat exchange components, and in engineering practice to replace the traditional smooth tube to obtain Provincial energy-saving double effect. T.C. Canavos has predicted that so far the work to strengthen the heat exchange element is just the beginning, but its benefits are so obvious that the elimination of plain smooth tubes is only a matter of time. Many years of practice have proved that this prediction is correct. In the heat-intensifying elements, the research on the elements that enhance liquid nucleate boiling nuclei is particularly prominent. Since the late 1960s, four kinds of tubes have been commercialized one after the other Species are T-finned tubes (Gewa-T). T-shaped finned tube since the advent of the Wieland Worke company in the former Federal Republic in 1978, a number of research at home and abroad
