Shell and tube heat exchangers are among the most prevalent types of heat exchangers, characterized by their straightforward design, durability, and relatively low acquisition and maintenance costs. Additionally, they exhibit an exceptionally high heat transfer efficiency.
A shell and tube heat exchanger comprises multiple tubes arranged within a cylindrical structure referred to as the ‘shell.’ The collection of tubes within the shell is commonly called a ‘tube bundle’ or ‘tube nest.’ Each tube traverses a series of baffles and tube sheets to facilitate optimal heat exchange.
The fluid flowing within the tubes is designated as the ‘tube side’ medium, while the fluid circulating outside the tubes is referred to as the ‘shell side’ medium. Each medium has a designated entry and exit point for efficient flow management.
