In order to solve the above problems, domestic and foreign High-efficiency heat exchangerintensification of A lot of research has been done on heat transfer technology, and it is important to make it more compact, with higher heat transfer efficiency and less flow resistance during operation. In summary, the enhanced heat transfer and structural development of shell-and-tube high-efficiency heat exchangers are mainly manifested in the following three aspects:

High Efficiency Heat Exchanger: In petroleum, chemical and power engineering, in order to maximize the utilization of thermal energy and recover waste heat, strengthening the heat transfer of heat exchange equipment has always been a hot research topic for scholars at home and abroad. The enhancement of the heat transfer process of the heat exchange equipment is to make the unit heat transfer area transfer as much heat as possible per unit time. The application of enhanced heat transfer technology can further improve the efficiency of heat exchange equipment, reduce the loss in the process of energy transfer, use energy more reasonably and effectively, and reduce equipment investment costs.

Traditional shell-and-tubeHigh-efficiency heat exchangerIt adopts the combined structure of smooth round tube and single arcuate baffle. The lateral flow on the shell side of the tube axis leads to a large heat transfer dead zone, which reduces the overall heat transfer efficiency and increases the flow resistance of the high-efficiency heat exchanger with this structure. When the Reynolds number is large, fluid-induced vibration often occurs, resulting in high efficiency Heat exchanger failed.

In order to solve the above problems, domestic and foreign High-efficiency heat exchangerintensification of A lot of research has been done on heat transfer technology, and it is important to make it more compact, with higher heat transfer efficiency and less flow resistance during operation. In summary, the enhanced heat transfer and structural development of shell-and-tube high-efficiency heat exchangers are mainly manifested in the following three aspects:

1.Develop and apply various new high-efficiency heat exchange tubes to enhance tube-side convective heat transfer. High Efficiency Heat ExchangerThe main purpose of the tube side is to change the shape of the heat exchange surface to increase the fluid turbulence and expand the heat transfer area. The tube structure is simple and the research is convenient. At present, a variety of reinforced pipe types such as threaded pipe (externally threaded pipe to strengthen the shell side), transverse corrugated pipe, corrugated pipe, zoom pipe, spiral flat pipe and so on have been developed.

2.Development and application of in-pipe inserts to enhance convective heat transfer on the pipe side, especially on the basis of the original equipment.

3.With the change of the tube bundle support (or baffle element), the fluid flow direction on the shell side changes from lateral flow to longitudinal flow or spiral flow, thereby enhancing the heat transfer on the shell side and improving the anti-vibration performance of the heat exchange tube bundle. The tube bundle support plays a turbulent role in the high-efficiency heat exchanger, which directly affects the fluid flow and heat transfer performance of the shell side, so it is a key component to improve the heat transfer coefficient of the shell side.
