Aluminum Heatsink
WANDA-AN
HS-al-0102
Engineered for optimal heat transfer in compact spaces, our Precision Aluminum Radiator Fins deliver high thermal efficiency through advanced geometry and surface treatments, ideal for automotive, HVAC, and electronics cooling. Manufactured from 1100-H14 aluminum (thermal conductivity 237 W/mK), these fins feature uniform thickness and precise spacing, maximizing heat dissipation in limited environments.
Optimized Heat Transfer Design
Micro-Fin Technology: 0.15mm-thick fins with 0.3mm spacing (20 fins per inch), increasing heat transfer area by 30% compared to conventional fins, validated by ASHRAE 41.1 testing.
Louvered Geometry: 30° louver angle enhances air turbulence, improving convective heat transfer coefficient by 18% in forced-air applications (air velocity 2-5 m/s).
Precision Manufacturing
High-Speed Stamping: Progressive dies (200 strokes/min) achieve fin flatness ≤0.05mm and thickness tolerance ±0.01mm, ensuring uniform airflow across heat exchangers.
Bonding Technology:
Roll-bonded fins to tubes (bond strength ≥10 N/mm) for brazed radiators, with optional soldering (Sn-99.3Cu-0.7Ni alloy) for high-reliability applications.
Surface Treatments
Chromate Conversion Coating: Compliant with MIL-DTL-5541 Class 1A, providing corrosion resistance (500h salt spray) and enhanced paint adhesion.
Hydrophilic Coating: Reduces water retention by 40% in HVAC evaporators, preventing mold growth and improving energy efficiency (AHRI 400 certified).
Automotive Radiators: Cools engine coolant and transmission oil in passenger cars and commercial vehicles, compatible with ethylene glycol and OAT coolants.
Electronic Cooling: Used in CPU heat sinks and power supply units, with fin heights 2-10mm for tight-space applications (e.g., mini PC, gaming laptops).
HVAC Systems: Enhances heat exchange in air conditioners and heat pumps, with fin lengths up to 1000mm for commercial rooftop units.
Thermal Performance Optimization
Computational fluid dynamics (CFD) simulations ensure optimal fin pitch and shape for target airflow conditions, reducing thermal resistance by 15% compared to standard fins.
High-Volume Production
10+ progressive die sets for fin sizes 50-500mm width, with annual production capacity of 50 million fins, supporting automotive OEMs and HVAC manufacturers.
Quality Control
100% visual inspection for fin damage (bends, burrs) and automated thickness measurement (laser gauge, accuracy ±0.005mm), compliant with IATF 16949.
Sustainability Commitment
100% recycled aluminum content options (post-consumer waste ≥70%) and energy-efficient stamping processes (50% lower power consumption), aligned with ISO 14001.
