Abstract In recent years, heat exchangers have been widely applied in the chemical, petroleum, and power industries, and pipe-type heat exchangers have the advantages of good heat transfer, strong structure, and flexible operation. The side reinforcement of pipe-type heat exchangers is usually achieved using asymmetric pipes, but the existing asymmetric pipes often need help with easy corrosion and difficult processing. To address this issue, this paper proposes a new reed pipe structure based on the reed pipe structure. Focusing on the structural variables of reed pipes and the influence of Reynolds number on the reed pipe flow heat transfer, the empirical correlation formula between each structural variable and Nu and f was fitted using multi-element non-linear regression. The results showed that in terms of heat transfer performance: node number>pharyngeal diameter>pharyngeal length; considering actual production manufacturing, the comprehensive heat transfer performance of the reed pipe has a pharyngeal diameter of 1.3 mm, a pharyngeal length of 3.0 mm, and a node number of 10 is the best.
