Progress on Heat Transfer Characteristics of Heat Exchangers with Different Structures

With the demand of industry and market, the demand for heat recovery and energy saving is also increasingly high, to meet the needs of industry and life, various types of heat exchangers have been published. By reading a lot of literature, this paper summarized the research status, type structure, and engineering application of heat exchangers, and focused on the development and application of plate, shell, and tube heat exchangers. By using the unsteady numerical simulation method, the heat transfer performance of the tube heat exchanger was analyzed comprehensively. By analyzing the wall temperature at different times, the theoretical basis was provided for further research and application of the heat exchanger.
