摘　　要：简要综述了管壳式换热器在工艺设计方面的最新进展。管壳式换热器的工艺设计方法在2 0世纪经历了 5 0年代的Kern法、6 0年代的Bell Delaware法和 70年代的流路分析法。随着计算机科学技术的发展 ,计算流体动力学方法应是 2 1世纪的主要设计方法。对目前设计仍然存在的诸如多相流设计、传热强化、流体诱导的振动、防垢和除垢、高粘流体设计、物性数据库的完善、换热器中流动及传热过程的数值模拟等问题进行了分析 。The up to date progress in the technology design including the calculation of pressure drop or flow and the calculation of heat transfer coefficient or thermo hydraulic performance of shell and tube heat exchangers,which is used most often in process industry,is reviewed.The technology design principle and method of this type of heat exchanger was established in the 50’s of twenty century. An example is the well known Kern method.The next stage of development of calculations of shell and tube heat exchanger was that commonly described as the Bell Delaware method built in 1963.The third step of progress in calculation method is the stream analysis method developed in the 70’s of twenty century. With the development of the computer,the method of computational fluid dynamics (CFD) is considered the most important design tools in the 21 century. In this work, some problems existing in the design practice such as the calculations of multi phase flow heat exchanger,enhancement of heat transfer,device vibration resulted from the fluid flow,fouling prevention,design for the flow with high viscosity,database building of physical properties of heat transfer media, numerical simulation of flow and heat transfer and so on are analyzed and the future research work is given.
