AI Technical Summary
Technical Problem
Traditional shell-and-tube heat exchangers have low heat transfer efficiency, and existing enhancement methods are not ideal, so further improvements in heat transfer performance are needed.
Method used
The baffles were replaced with an elastic tube bundle structure to increase the fluid contact area. Heat transfer was enhanced by the vibration of the free end of the elastic tube bundle and the fluid disturbance. The arrangement of the arc tubes and the fluid flow path were also optimized.
Benefits of technology
It significantly improves the heat transfer efficiency and descaling effect of the heat exchanger, reduces fluid short-circuiting, and enhances the heat transfer area of the fluid in the tube side and shell side, thus achieving more efficient heat transfer.

Abstract
This invention provides a shell-and-tube heat exchanger with an elastic baffle plate. The baffle plate is an elastic tube bundle structure, comprising multiple arc-shaped tubes. The centerlines of the multiple arc-shaped tubes are concentric circular arcs. Adjacent arc-shaped tubes are connected at one end and disconnected at the other, thus creating a free end at the connected end of the tube bundle. The outermost arc-shaped tube has an outer open end, and the innermost arc-shaped tube has an inner open end. The elastic tube bundle forms a series structure from the outer open end to the inner open end. By configuring the baffle plate as an elastic tube bundle structure, this invention increases the contact area between the two fluids, increases fluid turbulence, and improves the convective heat transfer coefficient of the shell side of the heat exchanger, thereby effectively improving the heat transfer efficiency.
