Shell-and-Tube Heat Exchanger Types & Features Comparison
Product Details
Shell-and-Tube Heat Exchanger Types & Features Comparison Table
| Type | Structural Characteristics | Typical Applications | Advantages | Disadvantages |
|---|---|---|---|---|
| Fixed Tube Sheet | Tubes are fixed at both ends to the tube sheet | Small temperature difference, infrequent shell-side cleaning | Simple structure, low cost | Difficult to clean shell side, not suitable for high temperature differences |
| Floating Head | One end is fixed, the other end can move (floating) | Large temperature difference, fouling fluids, frequent cleaning | Easy to clean, accommodates thermal expansion | Complex structure, higher cost |
| U-tube | Tubes are bent into U-shape, fixed at one end only | High thermal expansion conditions | Compact, good thermal expansion compensation | Difficult to clean tube interiors, can't replace individual tubes |
| Double Tube Sheet | Two tube sheets to separate fluids completely | Pharmaceutical, food, corrosive media | Prevents cross-contamination of fluids | Higher cost, more complex |
| Helical Baffle | Helical flow path with spiral baffles | High-viscosity or fouling-prone fluids | Lower pressure drop, higher efficiency, less fouling | Higher manufacturing cost, complex design |
