摘　　要：缠绕管式换热器广泛应用于煤化工装置,因其结构的特殊性,国内标准规范没有对其管板的设计计算方法做出规定。针对循环甲醇冷却器——一种典型的多股流缠绕管式换热器的管板在不同载荷条件下进行了有限元分析和应力评定,指出了有限元分析方法对于多股流缠绕管式换热器管板设计的经济性、实用性与安全性。Spiral wound heat exchangers have been widely used in coal chemical industry plants. Method of calculation for tube-sheet design has not been introduced in our standards and specifications because spiral wound heat exchanger has a special structure. Finite Elements Analysis and stress assessment have been carried out on tube-sheet of cycling methanol cooler,a typical multistream spiral wound heat exchanger in various load conditions. The viewpoint that FEA method has its economy,practicality, safety in tube-sheet design of a multi-stream spiral wound heat exchanger has been emphasized.
