Shell and tube heat exchanger is a commonly used heat exchange equipment, consisting of components such as shell and tube, tube bundle, and tube plate.
Its main working principle is to utilize the temperature difference inside and between pipes, transfer heat through the pipe wall, and achieve heat exchange between two or more fluids.
There are also various types of shell heat exchangers, such as spiral tube shell heat exchangers, air-cooled tube shell heat exchangers, air-insulated tube shell heat exchangers, etc,
Suitable types can be selected based on different process requirements and medium properties.
Advantages of shell and tube heat exchanger
1, Simple structure, convenient manufacturing, and low cost.
2, The tube bundle can freely stretch and has good thermal compensation ability.
3, Baffles and channels can be added as needed to change the fluid flow state and improve heat transfer efficiency.
4, Easy to clean and maintain, for fluids containing solid particles, shell and tube heat exchangers have better erosion resistance performance.
5, Strong pressure resistance, the inner part of the shell and tube heat exchanger is welded by argon arc welding,
and the pipeline is expanded, making its pressure resistance far superior to other types of heat exchangers
