Working Principle of Shell and Tube Heat Exchanger
Shell and tube heat exchangers are among the most commonly used heat transfer devices. They efficiently transfer heat between two fluids without mixing them. Their design ensures durability, reliability, and high thermal efficiency in industrial applications. Key Components of a Shell and Tube Heat Exchanger 1. Shell The shell is the outer casing that holds the internal tubes. It provides structural support and directs the fluid flow around the tubes. 2. Tubes The tubes carry the second fluid. Heat exchange occurs as one fluid flows inside the tubes and the other around them. 3. Tube Bundle A collection of tubes arranged inside the shell. It includes straight or U-shaped tubes to optimize heat transfer. 4. Baffles Baffles improve efficiency by directing fluid flow across the tubes. This increases turbulence and enhances heat transfer. 5. Tube Sheets Tube sheets hold the tubes in place and separate the fluids. They prevent leakage and ensure stability. 6. End Channels...
