摘　　要：管壳式换热器应用广泛尤其是对其设计的研究,回顾了近年来单台管壳式换热器的工艺设计方法,并指出这些方法难以兼顾换热网络的节能降耗。许多研究者,在换热网络最优综合的同时提出了多种面积裕量优化设计方法,虽然考虑了换热网络中各换热器换热面积的优化,但并未考虑换热器的选型与详细设计。近年来,也有研究者基于换热网络综合进行管壳式换热器的详细设计研究,同步优化换热网络和单台换热器的设计,但这些方法均是在给定的工况条件下进行设计,考虑到实际生产中工况条件经常发生变化,单台换热器的设计均采用超余设计难以保证总费用最小。最后,在此基础上,提出一种从灵敏度分析的角度出发以总费用最小为目标基于换热网络综合的管壳式换热器详细设计思路。Shell-and-tube exchangers （STHEs） are widely used in chemical process industries, and a considerable number of papers have been devoted to the design optimization problem. The study on STIlEs design method is summarized, but these methods are difficult to give consideration to saving energy and reducing consumption for heat exchanger networks （HENs）. The method of determining surface margin is summarized, which without the consideration of detailed design of STHEs. Come so far, many researchers presented the design of STHEs based on the HEN synthesis, but the overdesign or STHEs will increase the capital investments, from me perspective of sensmwty, analysising and designing STHEs is pointed out. The method of STHEs design based on sensitivity analysis is considered.
