Abstract：Plate-fin heat exchanger is the key equipment of cold box in the liquefaction plant of the low-concentration oxygen-contained coal-bed methane. In this paper, a new sealed-head structure of plate-fin heat exchanger with wing plate was put forward, numerical simulation was made on this new closed-head structure with CFD method, and analysis and comparison were carried out on its flow and pressure characteristics. The results showed that the new closed-head structure could effectively improve the distribution characteristics of fluid flow in the plate-fin heat exchanger and make the fluid flow to be uniformly distributed into every heat exchange channel. This research has a certain theoretical guiding significance for the design and manufacturing of the heat exchanger in the cold box.
