摘要
总结了近年来国内外新型管壳式换热器的研究进展,从管程、壳程、管束三方面介绍了管壳式换热器的发展历程、结构改进及强化传热机理,并与普通弓形折流板换热器进行对比,概括了各式换热器的强化传热特点。最后指出了换热器的研究方向。
The research progress of shell and tube heat exchanger were summarized.The development,structural improvement and heat transfer enhancement of the heat exchangers were introduced through three aspects,e.g.tube pass,shell pass and the whole tub bundle etc.Compared with the traditional segmental baffle heat exchanger,various types of heat exchangers′ characteristics about heat transfer enhancement were epitomized.At last,the studying directions of heat exchangers were pointed out.
