摘要: 换热器的结构优化涉及到多参数的耦合问题.区别于以往优化方法只是将换热器单个性能涉及因素作为目标函数,选取换热器性能涉及因素中的换热体积和换热过程压降损失为优化对象,以湿空气与水热交换作为具体工况条件,分析了管壳式换热器的传热和压降模型,得到了管壳式换热器设计的优化结果,找到了一种综合考虑换热器体积以及换热过程压降损失的换热器结构设计方法.与普通设计方法相比,该方法可以有效减小换热器体积与传热过程压降损失.Abstract: The optimal design of the heat exchanger structure is a coupling problem with several parameters. Exchanger cubage and the pressure loss of the exchanger performance factors was selected as the optimal object. In the condition of moist air and water heat exchange, the heat transfer and pressure loss model and the influence factors of the structure of the shell-and-tube heat exchanger was analyzed. A mathematics model and an optimization design were built for the exchanger. A structure design method which was used to synthetically evaluate the problems of the exchanger cubage and the pressure loss was developed. Compared with common design method, this method could effectively reduce the exchanger cubage and the pressure loss.
