  • Floating Type Shell And Tube Heat Exchanger

The shell-and-tube heat exchanger is composed of a casing, a heat transfer tube bundle, a tube sheet, a baffle (baffle), and a pipe box. The housing is mostly cylindrical, and a tube bundle is installed inside, and both ends of the tube bundle are fixed on the tube sheet. The two types of hot and cold fluids that perform heat exchange, one flowing in the tube, called the tube-flow fluid, and the other flowing outside the tube, called the shell-side fluid.

Product Description

The shell-and-tube heat exchanger is composed of a casing, a heat transfer tube bundle, a tube sheet, a baffle (baffle), and a pipe box. The housing is mostly cylindrical, and a tube bundle is installed inside, and both ends of the tube bundle are fixed on the tube sheet. The two types of hot and cold fluids that perform heat exchange, one flowing in the tube, called the tube-flow fluid, and the other flowing outside the tube, called the shell-side fluid. 


In order to increase the heat transfer coefficient of the fluid outside the tube, a number of baffles are usually installed in the housing. The baffle increases the speed of the shell-side fluid, forcing the fluid to pass laterally through the tube bundle multiple times over a specified path, enhancing fluid turbulence. The heat exchange tubes can be arranged on the tube sheets in an equilateral triangle or square. The equilateral triangles are arranged in a compact manner, the fluid outside the tube is highly turbulent, and the heat transfer coefficient is large; the square arrangement is convenient for cleaning outside the tube, and is suitable for fluids that are easy to scale.

Each time the fluid passes through the tube bundle, it is called a tube process; each time it passes through the shell, it is called a shell side. The illustration is the simplest single-shell single-tube heat exchanger, referred to as the 1-1 heat exchanger. In order to increase the fluid velocity in the pipe, spacers may be provided in the pipe boxes at both ends, and all the pipes are divided into several groups. This way the fluid passes through only a portion of the tube at a time and thus travels back and forth a plurality of times in the tube bundle, which is called multi-tube. Similarly, in order to increase the flow rate outside the tube, a longitudinal baffle can also be installed in the housing to force the fluid to pass through the housing space multiple times, which is called a multi-shell process. Multi-tube and multi-shell can be used together.



The main advantage of the shell and tube technology is to offer a wide range of configurations to meet your expectations. The operational constraints of the process are taken into account by our engineering team, highly specialized in thermal and mechanics, in order to propose the right heat exchanger configuration.
