Hydrophilic aluminum foil


亲水铝箔.jpg

Product Introduction
Hydrophilic aluminum foil is processed through a special hydrophilic treatment, forming a water-absorbing layer on its surface. This allows condensation water to spread rapidly and uniformly across the foil, preventing water droplet formation. The expanded surface area accelerates heat exchange rates, enhances cooling/heating efficiency, and eliminates noise caused by condensed water obstructing airflow. As a primary material for air conditioner heat exchangers, it significantly impacts system performance. Using hydrophilic aluminum foil in heat exchangers can improve refrigeration efficiency by 5%, while also offering corrosion resistance, mold prevention, and odor control. It avoids water droplet accumulation that could block heat exchange, ensuring optimal performance.

Product Specifications

  • Aluminum Plate & Strip National Standard: GB/T 3880-2006 (Chinese national standard for aluminum plate and strip materials). According to this standard, aluminum sheets with thickness ≤0.2mm are classified as aluminum foil.

Key Features

  1. Superior Hydrophilicity & Corrosion Resistance

  2. Excellent Formability & Mold Compatibility (low tool wear)

  3. Resistance to Stamping Oils, Solvents & Heat

  4. Reduced Airflow Resistance (Heat exchange efficiency improves by 10%-15%)

Applications
Hydrophilic foil is widely used in:

  • Household air conditioners

  • Refrigeration cabinets

  • Automotive air conditioning systems

Advantages Over Ordinary Bright Foil

  1. Enhanced corrosion resistance, mold prevention, and odor control

  2. Condensed water spreads uniformly across heat exchanger surfaces, avoiding droplet accumulation that blocks airflow and reduces heat exchange efficiency by 5%

  3. Reduced vibration-induced noise due to elimination of water droplets

  4. Prevents aluminum oxide powder from circulating into indoor spaces, meeting environmental health standards

  5. Heat exchanger components must comply with YS/T 95.2—2001 (Chinese industry standard for hydrophilic aluminum foil in air conditioners)
