Abstract

Abstract:

Since the heat exchanger plates are designed along vertical direction, the uniform level of the inlet medium has vital effect on the whole efficiency of cooling rate. The multi-holes distributor optimum design was discussed.The structure design of multi-holes distributor was put forward and the design method was mathematically described ,then deduced the formula of pressure reduction. Flow pattern in the distributor was simulated by CFX software. The results show that the effect of uniform distribution is good. These have some importance to fundamental thought of distributer optimum design and formular reduction of pressure on the distributor design.

Key words:

摘要： 板式空冷器的板束为垂直设计,因此,介质进入板束时的均布程度对于空冷器的冷却效率有重要的影响。对分布管式液体分布器的结构进行了研究,提出了变孔径多孔直管液体分布器的结构,对变孔径设计方法进行了数学描述,推导得出了其结构压降公式。采用CFX软件对该结构进行流场模拟,从结果图来看,均布效果良好。所提出的结构设计基本思想和压降公式对于板式空冷器液体分布器的设计具有一定的理论指导意义。
