Why are shell-and-tube heat exchangers designed to be slender rather than thick and short?
Add processes to increase the heat exchange depth.
Can thickening and shortening a shell-and-tube heat exchanger while maintaining the heat exchange area ensure the original heat exchange efficiency?

An appropriate length-to-diameter ratio; it remains slender only when installed vertically. Horizontal installation takes up space.
If it changes again, it will become a shell-and-tube heat exchanger
Its elongated shape allows for an increased contact time between the hot and cold media, thereby enhancing the heat exchange efficiency.
Thicker pipes require more of them, resulting in higher costs! Slender, with a small number of tubes, and relatively low cost
The key is the heat exchange efficiency; it doesn’t matter whether it’s short and thick or thin and long, as long as there’s space available.
Slender heat exchangers have higher flow velocities in the tube side and shell side, resulting in better heat exchange efficiency
