Research progress of heat transfer enhancement of shell-and-tube heat exchanger
摘要
Abstract
As the most widely used heat exchangers in engineering,shell-and-tube heat exchangers have the advantages of strong structure,high adaptability,ability to utilize and recover heat energy and so on. Under the background of pursuing high-energy efficiency,the heat transfer enhancement of heat exchangers has attracted wide attention. This article mainly focuses on the research progress of heat transfer enhancement of shell and tube heat exchanger,including the optimization of geometry of the heat exchanger,the improvement of thermal properties of the flowing fluid and the combination of multiple heat transfer enhancement techniques. Among them,the geometry optimization mainly includes changing the surface of the heat transfer tubes,adding inserts into tubes,and optimizing the baffles in the shell side. The optimization of the physical properties of flowing fluid mainly focus on the improvement of thermal conductivity of nanofluids,and improvement of heat capacity of latent heat fluid and so on. Integrated enhanced heat transfer technique combined different enhancement methods to fill the gap and achieve higher heat transfer rate. Finally,it is pointed out that the research direction of the heat transfer enhancement of shell and tube heat exchanger in the future lies in developing enhanced tubes and steady nanofluids and latent heat fluid,and the combination of a variety of ways to strengthen the heat transfer effect.关键词
