Compared with the ordinary header, the experimental results show that staggered perforated plate header greatly improves the distribution of outlet flow and outlet temperature. 通过实验与工业用基本型封头对比,结果表明错排孔板型封头能够明显地改善换热器出口截面流量和温度分布的不均匀性。
It is considered that Re is the critical factor influencing the both, while the improvement of staggered perforated plate header configuration is of optimal effect. 综合研究分析可得封头结构和Re是影响板翅式换热器物流分配和阻力分布特性的重要因素,而错排孔板型封头结构的改善效果最佳。
