Study on the Impact of Plate-fin Heat Exchanger Fins to Heat Transmission Performance and Resistance Performance

With the development of technology, the heat exchangers are developing towards compaction, light-weight and miniaturization. As one of the compact heat exchangers, the plate-fin heat exchanger can well meet the requirement of this feature. This article is based on an example of a plate-fin heat exchanger whose fin material is aluminum, by theoretical analysis and practical calculation, this article focuses on the influence on the heat transmission performance and resistance performance caused by the change of fins thickness, plate spacing and fins pitch. And it aims at providing more detailed theoretical basis for the optimization of plate-fin heat exchanger.
