Shell and Tube Heat Exchanger
Shell and Tube Heat Exchanger
Blog Article
A Shell and Tube Heat Exchanger is a type of heat exchanger that consists of a series of tubes enclosed within a cylindrical shell. It is one of the most commonly used heat exchangers in industries like power plants, chemical processing, HVAC, refrigeration, and marine applications.
Main Components
- Shell – The outer vessel that holds the tube bundle.
- Tube Bundle – A set of tubes that carry one of the fluids.
- Tube Sheets – Plates at each end of the exchanger that hold the tubes in place.
- Baffles – Internal plates that direct fluid flow and improve heat transfer.
- End Channels & Covers – Control the entry and exit of the tube-side fluid.
How It Works
- One fluid flows inside the tubes (tube-side fluid), while another fluid flows around the tubes within the shell (shell-side fluid).
- Heat is transferred between the two fluids without direct mixing.
- Baffles enhance turbulence, improving heat transfer efficiency.
Advantages
✔ High heat transfer efficiency
✔ Handles high pressures and temperatures
✔ Suitable for both liquid-liquid and gas-liquid heat exchange
✔ Easy maintenance and cleaning (especially in removable bundle designs)
Common Applications
???? Oil refineries
???? Power plants
???? Chemical processing
???? Marine industry (engine cooling)
???? HVAC systems
