1) Perforated Plate Header
孔板型封头
2) perforated plate header configuration
孔板型封头结构
1.
The experiment result indicates that the maldistribution would be caused by the ordinary industrial header for the internal flow of the plate-fin heat exchanger, while the maldistribution parameters and the maximum velocity ratio can be effectively reduced by perforated plate header configuration, the effect of flow distri.
实验结果表明工业用基本型封头造成板翅式换热器内部物流分配极不均匀,而孔板型封头结构能有效地降低不均匀参数和最大流速比,可极大地改善物流分配的效果,并且随着Re的增大效果越明显;还发现物流分配的不均匀性会导致流动阻力分布更加不均匀。

孔板封头
5) staggered perforated plate header configuration
错排孔板型封头结构
6) spherical-zone shell
开孔封头
