Heat exchangers are widely used in various industries to transfer heat from one medium to another. Among different types of heat exchangers, the shell and tube heat exchanger is one of the most commonly used due to its efficiency, reliability, and versatility.
In this blog post, we’ll take a closer look at the basics of shell and tube heat exchangers and how they work
A shell and tube heat exchanger is a type of heat exchanger that consists of a shell (a large pressure vessel) with a bundle of tubes inside it. The tubes are usually made of metal and are arranged in a parallel pattern inside the shell.
The process fluid (also known as the hot fluid) flows through the tubes, while the service fluid (also known as the cold fluid) flows around the tubes in the shell. Heat is transferred from the hot fluid to the cold fluid through the tube walls.
Shell and tube heat exchangers work based on the principle of heat transfer by convection and conduction. As the hot fluid flows through the tubes, it gives up heat to the tube walls by convection. The tube walls, in turn, transfer the heat to the cold fluid flowing around the tubes by conduction.
Shell and tube heat exchangers are designed to withstand high pressures and temperatures. The shell is usually made of a metal alloy such as carbon steel, stainless steel, or titanium, while the tubes can be made of various materials such as copper, brass, Cupronickel, or stainless steel.
The tubes are usually attached to the tube sheets at each end of the shell, and the tube bundle is then inserted into the shell. The shell is closed by a flanged cover, and the fluid connections are made through nozzles on the shell and tube sheets.
