摘要：
Aiming at the characteristics of multi-stream flow heat transfer, complex fin structure optimization, multiple channel configuration matching, and cryogenic engineering application, this study summarizes several problems in the thermal design of multi-stream plate-fin heat exchanger (MPHE), such as heat transfer matching, layer pattern, multi-physical field superposition, and special cryogenic operating condition. In the layer structure design and optimization, the heat-transfer flow characteristics and related performance evaluation methods of the fins are summarized to provide guidance for the structural selection. The current research hotspots and development directions of plate-fin heat exchangers are discussed according to the present situations. The results show that MPHE has great advantages in large-scale air separation and petrochemical industries, which can significantly improve the operation efficiency through increasing the gas liquefaction rate and reducing the actual energy consumption. Therefore, the local heat exchange network and multi-stream matching should be combined with the fin structure design and layer algorithm optimization using the multi-field simulation and experimental research to overcome the design problems occurred in practice. This comprehensive and efficient optimization design method can be formed to get rid of the limitations of traditional empirical design. © 2021, Chemical Industry Press Co., Ltd. All right reserved.
