Experimental Research on Flow Maldistribution in Plate-Fin Heat Exchangers

Abstract

Abstract: The flow maldistribution and the effect of different inlet configuration on the flow
distribution in platefin heat exchangers were studied experimentally. It is found that the
flow maldistribution is serious because of the defects of inlet configurations, while the
inlet configuration and Reynolds number are the main factors affecting the flow
distribution. The improved inlet configurations, which are the header with a two-stage
distributing configuration and the guide vane with a fluid complementary cavity were
proposed and tested in this paper. The experimental results show that the improved inlet
configurations can effectively improve the performance of flow distribution in heat
exchangers.

Key words: plate-fin heat exchanger, flow distribution, inlet configuration
