Abstract:The implementation of enhanced heat transfer technology in heat exchangers can solve the bottleneck problem in the existing heat exchanger network(HEN)retrofit. Without excessive structural transformation in the heat recovery system,the use of heat transfer enhancement technology can achieve significant energy savings and reduce costs. At the same time,in the design of HEN,the application of heat transfer enhancement technology in heat exchangers can reduce the investment of equipment and achieve better economic effect. Firstly,through the literature retrieval data,the research on heat transfer enhancement in heat transfer network retrofit and design has been paid attention by researchers in the last 5 years. Then,the basic principles and main methods of heat transfer enhancement of shell and tube heat exchangers(STHE)were summarized. The effect of heat transfer enhancement technology on heat transfer performance of heat exchanger was analyzed. The classification of heat transfer enhancement technology and the enhancement effect of STHE were summarized. From the two aspects of design and retrofit,the application research of heat transfer enhancement of STHE considering in the optimization of HEN was summarized. The effect and advantage of heat transfer enhancement on HEN design and retrofit were presented. Finally,the future research,the simultaneous optimization of heat transfer enhancement device geometry of STHE and HEN,as well as simultaneous optimization of heat transfer enhancement and detailed design of heat exchanger was prospected.
