Aluminium Extruded Fin Tubes Applications

‌Technical Documentation for Aluminium Extruded Fin Tubes‌
‌Core Technical Specifications Covering Structure, Manufacturing, 공연, and Applications‌

---

‌나는. Material and Structural Design‌

1. ‌재료 선택‌

   • ‌Base tube‌: Stainless steel or carbon steel for mechanical strength and corrosion resistance.
   • ‌Fins‌: Aluminum or alloy (예), steel-aluminum composite) to balance thermal conductivity and lightweight requirements.

2. ‌Structural Features‌

   • ‌Metallurgical bonding‌: Achieved via extrusion, ensuring contact thermal resistance < ‌0.01 m²·K/W‌, superior to mechanical attachment.
   • ‌Optimized geometry‌: Fin spacing (2–10 mm), height, and arrangement (spiral/straight) tailored to fluid type (gas/liquid) to maximize turbulence.

‌2 세. 제조공정‌

1. ‌Extrusion Technology‌

   • ‌Integrated forming‌: Base tube and fins are bonded via high-frequency welding or thermal extrusion under controlled conditions (pressure ≥50 MPa, temperature 300–500°C).
   • ‌Surface treatment‌: Aluminum fins require pre-cleaning to remove oxide layers for enhanced adhesion.

2. ‌Key Process Parameters‌

   매개 변수	Typical Range
   Fin spacing	2–10 mm
   Fin thickness	0.2–1.5 mm
   Base tube pressure	0.6–6.4 MPa

‌3세. Performance and Testing Standards‌

1. ‌Thermal Performance‌

   • ‌Heat transfer coefficient‌: Airside: ‌30–60 W/(m²·K)‌; liquid side: up to ‌2000 W/(m²·K)‌.
   • ‌Pressure drop‌: Airside ≤200 Pa at 1–3 m/s flow velocity, validated via CFD simulations.

2. ‌Quality Control‌

   • ‌Non-destructive testing‌: X-ray inspection for weld defects in base tubes.
   • ‌Dimensional tolerance‌: Fin height deviation ≤±0.3 mm; spacing deviation ≤±0.5 mm.

‌정맥. Applications and Selection Guidelines‌

1. ‌Typical Applications‌

   • ‌Power industry‌: Transformer oil coolers.
   • ‌Chemical plants‌: Waste heat recovery in reactors.
   • ‌HVAC 시스템‌: Condensers and evaporators.

2. ‌Selection Criteria‌

   • ‌High-temperature/corrosive environments‌: Stainless steel base tubes recommended (＞200°C).
   • ‌Forced convection‌: Reduced fin spacing to enhance turbulence.

‌V. Maintenance and Limitations‌

1. ‌Maintenance Requirements‌

   • ‌Regular cleaning‌: Remove dust accumulation in fin gaps to prevent efficiency loss.
   • ‌Irreparable damage‌: Full replacement required due to integrated structure.

2. ‌Technical Constraints‌

   • ‌Corrosion susceptibility‌: Aluminum fins in sulfur-rich environments require protective coatings.
   • ‌High initial costs‌: High-frequency welding equipment limits cost-effectiveness for small-scale production.
