Explanation of Common Fin Types

Fin TypeDescriptionAdvantages
L-FinL-shaped fin tightly wound around the tube.Cost-effective, moderate efficiency, suitable for low to medium operating temperatures.
G-FinG-shaped groove is cut into the tube, and the fin is inserted into the groove.Better mechanical bond, improved thermal performance compared to L-Fins.
Embedded FinFin is embedded into the tube wall for a strong mechanical bond.High strength, excellent thermal conductivity, suitable for high temperatures.
Extruded FinFin is formed by extruding the base tube and fin as a single piece.Superior strength and corrosion resistance, suitable for high-pressure and high-temperature environments.
Serrated FinFins are segmented to increase heat transfer efficiency by promoting turbulence.Maximum heat transfer efficiency, widely used in high-efficiency applications like REAC.

Key Considerations for REAC Fin Tube Selection

  1. Material Compatibility: Choose tube and fin materials based on the operating environment (e.g., corrosive media, high temperature).
  2. Thermal Efficiency: Use serrated or embedded fins for maximum heat transfer efficiency in high-performance REAC systems.
  3. Mechanical Strength: Ensure the fin-tube bond can withstand high operating pressures and temperatures.
  4. Customization: Tube length, fin pitch, and fin height should be customized based on specific REAC design requirements.
  5. Corrosion Resistance: Stainless steel or extruded fins are preferred for environments prone to corrosion.
