摘　　要：针对三氯化磷工艺氯化反应的温度控制问题,通过计算流体力学方法,设计了一种新型的穿孔百叶窗翅片导热结构,并分析了开孔尺寸与排列方式对穿孔百叶窗翅片热工水力特性的影响。结果表明:开孔尺寸与穿孔百叶窗翅片热工水力特性正相关,而孔排列方式的影响较小。具有最大孔尺寸的穿孔百叶窗翅片表现出较好的综合性能,在雷诺数191~476范围内,其综合性能因子较常规百叶窗翅片平均提升4.9%。Heat transfer plays a crucial role in the microchannel reaction process.Addressing the temperature control challenges in the chlorination reaction of phosphorus trichloride,a novel perforated louvered fin heat transfer structure was designed using computational fluid dynamics methods.The study analyzed the effects of perforation size and arrangement on the thermal-hydraulic performances of the perforated louvered fins.Results indicate a positive correlation between perforation size and the thermal-hydraulic performance of the perforated louvered fins,whereas the arrangement of the perforations had a relatively minor impact.In this study,the perforated louvered fins with the largest perforation size exhibited the best overall performance.The comprehensive performance factor was 4.9%higher than that of conventional louvered fins within the Reynolds number range of 191 to 476.
