| Layout | Advantage | Trade-off |
|---|---|---|
| Triangular (30°/60°) | Higher tube density, more heat transfer area | Harder mechanical cleaning on shell side |
| Square (90°) | Better lane cleaning access | Fewer tubes for same shell diameter |
| Rotated square (45°) | Compromise density/access | Layout-specific baffle design |
