本文提出了一种基于结构理论的换热器设计通用优化设计方法。提出了该设计方法的简化版本，并给出了优化问题公式。该方法将一个整体换热器分成若干个串并联布置的子换热器。该方法应用采用管壳式换热器，所有设计参数均严格遵循管式换热器制造商协会 (TEMA) 标准。管径、布置、厚度和数量。适应度函数是管壳式换热器的总成本，包括初始制造的投资成本和涉及克服摩擦压力损失的电力消耗的运行成本。应用遗传算法通过调整参数来最小化目标函数。三个案例研究表明，与原始设计、传统遗传算法设计和旧结构设计的方法相比，新的设计方法可以显着降低总成本。
A general optimization design method motivated by constructal theory is proposed for heat exchanger design in the present paper. The simplified version of this design approach is suggested and the optimization problem formulations are given. In this method, a global heat exchanger is divided into several sub heat exchangers in series-and-parallel arrangement. The shell-and-tube heat exchanger is utilized for the method application, and the Tubular Exchanger Manufacturers Association (TEMA) standards are rigorously followed for all design parameters, e.g. tube diameter, arrangement, thickness and number. The fitness function is the total cost of the shell-and-tube heat exchangers, including the investment cost for initial manufacture and the operational cost involving the power consumption to overcome the frictional pressure loss. A genetic algorithm is applied to minimize the objective function by adjusting parameters. Three case studies are considered to demonstrate that the new design approach can significantly reduce the total cost compared to the methods of original design, traditional genetic algorithm design, and old constructal design.
