2. Aluminium G-Type Fins

• G-Type Finning:
  • The G-type fin (groove type) involves embedding aluminium fins into grooves cut into the outer surface of the tube, followed by mechanically locking the fins in place.
  • This provides a strong mechanical bond with excellent thermal conductivity.
• Aluminium Fins:
  • High Thermal Efficiency: Aluminium is lightweight and has excellent thermal conductivity.
  • Durability: Resistant to corrosion in most industrial environments.
  • Improved Surface Area: The fins significantly increase the heat transfer surface area, optimizing efficiency.

3. Use in Air Coolers

• Role of Air Coolers:
  • Air coolers use ambient air to cool process fluids, making them essential in industries such as power generation, petrochemical plants, and refineries.
  • They are particularly effective in locations where water for cooling is scarce or costly.
• Why G-Type Fins for Air Coolers:
  • The robust bond between the fins and the tube ensures long-term performance in dynamic thermal cycles.
  • G-type fins are highly resistant to vibrations caused by airflow, making them ideal for air coolers.
