Learn about hydrophilic aluminum foil
Aluminum foil is the primary material for air conditioning coil construction due to its excellent thermal conductivity and lightweight properties. Hydrophilic aluminum foil goes a step further and is water-absorbent or hydrophilic. Simply put, hydrophilic surfaces promote easy diffusion of water across the material, preventing water droplets from forming and increasing heat exchange efficiency.
Hydrophilic aluminum foil is a special material for manufacturing air conditioning heat exchanger fins. The air conditioning foil used in the early days was ordinary foil. In order to improve the surface properties of the plain foil, an anti-corrosion inorganic coating and a hydrophilic organic coating are applied before forming to form a hydrophilic foil.
The meaning of blue coating
The introduction of a blue coating on hydrophilic aluminum foil is a key innovation in the air conditioning industry. Blue coating has many uses:
A. Enhanced Corrosion Resistance: The blue coating acts as a protective layer to prevent corrosion of the aluminum foil. This is especially important for air conditioning systems that are inevitably exposed to moisture.
B. Improved hydrophilicity: The blue coating enhances the hydrophilicity of the aluminum foil and promotes better drainage. This is especially important in humid conditions, where condensation is a common challenge.
C. Heat Reflectivity: The blue color of the coating helps improve heat reflectivity. This means that the coated foil effectively reflects a portion of the solar radiation, reducing the overall heat load on the air conditioning system.
8011 Blue Hydrophilic Aluminum Foil
Hydrophilic aluminum foil accounts for 80% of the volume of air-conditioning aluminum foil. Compared with aluminum fin blanks, the surface of the aluminum foil has an anti-corrosion hydrophilic layer, so the aluminum foil has anti-corrosion, anti-mildew functions and no odor;
Compared with finned aluminum foil, its cooling efficiency is increased by 5%, so it is a more ideal heat exchange material for air conditioning.
It can reduce noise and ensure the long-term and stable heat exchange effect of the air conditioner.
