摘　　要：通过Solidworks软件建立弓形折流板换热器三维网格模型,采用ANSYS软件,运用单一评价方式和热增强因子综合评价方式研究折流板数和缺口高度对传热性能的影响。模拟研究结果表明:当折流板数为4、缺口高度为1/4D时,可获得较好的弓形折流板换热器的综合热工水力性能。另外,通过研究折流板数和缺口高度之间的相互关系,可为弓形折流板的结构参数优化提供设计思路。The three-dimensional mesh model of the segment baffle heat exchanger was established by SolidWorks software. The influences of the number of baffles and the height of baffle notch on the comprehensive thermal hydraulic performance of the shell side fluid were studied by using ANSYS software with the single evaluation method and the comprehensive evaluation method. The simulation results showed that better comprehensive thermal hydraulic performance of the segment baffle heat exchanger could be obtained when the number of baffles was 4 and the height of baffle notch was 1/4D. Furthermore, the relationship between the number of baffles and the height of baffle notch was investigated in order to provide the design idea for the optimization of the structural parameters of the segment baffle shell and tube heat exchanger.
