Copper Finned Tube and Fin Automotivo Heavy Duty Ac Condenser

Copper finned tube is the core element for enhancing heat transfer in Fin Automotivo Heavy Duty Ac Condenser. By adding fin structure on the outer surface of copper-based tube, its heat exchange area can be expanded by 3 to 10 times compared with plain tube, significantly improving heat transfer efficiency, especially suitable for heat dissipation needs in compact space of construction machinery.

Copper Finned Tubes in Caterpillar Heat Exchangers

Copper finned tubes are the core heat transfer enhancement elements in Caterpillar heat exchangers‌1. By adding fin structures to the outer surface of copper base tubes, their heat exchange area can be increased by 3 to 10 times compared to bare tubes‌34, significantly improving thermal efficiency. This design is particularly suited for heat dissipation requirements within the compact spaces of construction machinery.

Core Characteristics & Application Advantages:

  1. Structural Design

    • Utilizes copper base tubes (common inner diameters: 9.52–19.05mm) combined with aluminum or copper fins‌2. Tight bonding is achieved through high-frequency welding and tube expansion processes‌12, leveraging copper’s thermal conductivity alongside aluminum’s lightweight and cost benefits.
    • Spiral fin configurations (pitch: 2–10mm) are predominant for enhanced air turbulence; longitudinal straight fins are used in some high-temperature scenarios‌.
  2. Performance Advantages

    • High-Efficiency Heat Transfer:‌ Fins expand the heat transfer surface, increasing the gas-side heat transfer coefficient to 50–80 W/(m²·K), boosting efficiency by 3–5 times compared to bare tubes‌.
    • Pressure Resistance & Corrosion Resistance:‌ Copper base tubes resist coolant corrosion, with pressure resistance reaching 3.2 MPa (standard) to 4.0 MPa (special conditions)‌, suitable for the vibration environments of construction machinery.
    • Compactness:‌ Achieves 40%–60% volume reduction compared to traditional heat exchangers for equivalent heat transfer capacity, accommodating equipment space constraints‌.
  3. Manufacturing & Maintenance

    • Production requires salt spray testing (≥100 hours for corrosion resistance) and 2.5 MPa uniform pressure testing‌.
    • Avoid organic solvents during maintenance. Diluted white vinegar is recommended for fin cleaning. Use 6 bar compressed air for counter-flow dust removal every 600 operating hours‌.

Typical Application Scenarios

Caterpillar heat exchangers utilize these finned tubes for:

  • Engine Cooling Systems:‌ Coolant flows inside copper tubes; fins enhance air-side heat dissipation to manage thermal loads‌.
  • Hydraulic Oil Cooling:‌ Corrugated fin designs reduce oil passage fouling, maintaining oil temperature stability‌.
  • Exhaust Heat Recovery:‌ Carbon steel composite finned tubes are used on the high-temperature flue gas side to recover waste heat for driving auxiliary systems‌.

This design optimizes fin parameters (e.g., fin spacing: 1.8–3.5mm) to balance heat exchange efficiency and airflow resistance, meeting the high-reliability demands of construction machinery‌.
