Description

Technical Field

[0001] The utility model relates to a baffle and a shell and tube heat exchanger. Background Art

[0002] Baffles are a component used in shell and tube heat exchangers to change the flow direction, diffuse or evenly distribute the fluid. They can be designed to be integrally formed. Integrally formed baffles are usually a single structure made by casting, injection molding or metal sheet stamping. This structure usually has good strength and sealing performance because it has no seams.

[0003] However, the one-piece molded baffle is poor in customization and flexibility, and the mold needs to be remade when the design changes, which is extremely disadvantageous for customization and small-batch production. Moreover, when the baffle is damaged, the entire unit may need to be replaced, which will affect the normal production process. In view of this, the utility model proposes a baffle and a shell and tube heat exchanger to solve the above problems. Utility Model Content
