Shell & Tube Heat Exchanger

Shell and tube heat exchangers are most common types of heat exchanger having a simple design, robust characteristics and relatively low purchase and maintenance costs. They also have a very high heat transfer rate

A shell and tube heat exchanger consists of number of tubes installed within a cylinder known as a ‘shell’. All tubes within the shell are collectively termed a ‘tube bundle’ or ‘tube nest’. Each tube passes through a series of baffles and tube sheets.

The flowing medium within the tubes is known as the ‘tube side’ medium. The flowing medium outside of the tubes is known as the ‘shell side’ medium. Each medium has one entry and one discharge.
