摘要
The effects of different header configurations on the flow distribution in plate-fin heat exchangers are experimentally studied. It is found that the flow maldistribution in plate-fin heat exchangers is very serious because of the improper header configuration. Header configuration and Reynolds number are the main factors affecting the flow distribution in plate-fin heat exchangers. A secondary header configuration is proposed. The definitions of the equivalent area and its diameter are given to describe the characteristics of the secondary header configuration. The results show that the flow distribution in plate-fin heat exchangers can be effectively improved by changing the header configuration. It is also found that the effect of header configuration on the flow maldistribution in crosswise direction at the outlet area is greater than that in lengthwise direction. The correlations of the flow maldistribution characteristic with Reynolds number are obtained under different header configurations.
