Fins are the basic components of plate fin heat exchangers, and the heat transfer process is mainly completed through fin heat conduction and convective heat transfer between fins and fluids. The function of fins is to expand the heat transfer area and improve compactness. Fins can be seen as extensions and expansions of partitions; Meanwhile, due to the much larger surface area of the fins compared to the partitions, the compactness coefficient is significantly increased. b. Improve heat transfer efficiency. Like the special structure of fins, the fluid forms strong disturbances in the channel, causing the boundary layer to continuously rupture and regenerate, effectively reducing thermal resistance and improving heat transfer efficiency. c. Improve the pressure bearing capacity of the heat exchanger. Due to the support and reinforcement of the fins, the core forms a solid whole, so even though the partition and fins are thin, they can withstand a certain amount of pressure. According to different working fluids and heat transfer conditions, fins can adopt different structural forms.
