A shell and tube heat exchanger with periodic flow splitting
By setting up upper and lower seals in the shell and tube heat exchanger, periodic divergence is achieved, and circulating disturbances in the baffle cavity is formed, which solves the problem of unsatisfactory heat transfer effect of traditional heat exchangers, and achieves a more efficient heat exchange effect and a larger heat exchange area.

AI Technical Summary
Technical Problem
Traditional shell and tube heat exchangers have shortcomings in enhancing heat transfer effects, and a single method cannot effectively improve heat transfer efficiency.
Method used
By setting up the upper and lower seal heads, the fluid flow rate of the upper and lower seal heads is different, forming a periodic shunt, resulting in a cyclic disturbance of the fluid in the baffle cavity, thereby further enhancing heat transfer.
Benefits of technology
A more efficient heat transfer effect is achieved, the overall heat exchange efficiency of the heat exchanger is improved, and the heat exchange area and ability to remove impurities are increased through the design of the cavity structure.

Abstract
The present invention provides a shell and tube heat exchanger with periodic flow diversion, wherein the front head is divided into two parts, an upper part and an lower part, by a partition, wherein the upper heat exchange tube is connected to the upper head, and the lower heat exchange tube is connected to the lower head, and the upper head and the lower head are respectively provided with an upper inlet and a lower inlet, and the fluid flow rates of the upper inlet and the lower inlet can be controlled separately, and the fluid flow rates of the upper head and the lower head are different, so that the fluid flow rates entering the upper heat exchange tube and the lower heat exchange tube are different. The present invention sets the upper and lower heads so that the fluid flow rates of the upper and lower heads are different, so that the heat exchange tube with more fluid can form a greater impact on the inside of the cavity, so that the fluid in the baffle cavity forms an upward or downward disturbance, thereby forming a circulating flow inside, further enhancing heat transfer.
