Hydrophobic aluminum foil fin is an aluminum foil material whose surface has been specially treated to make it hydrophobic. This aluminum foil fin can effectively prevent condensation water from adhering, thereby improving the efficiency and service life of the heat exchanger. It is widely used in the manufacture of heat exchangers such as air conditioners and refrigeration equipment.
The surface of superhydrophobic foil has properties such as anti-condensation, corrosion resistance, self-cleaning, and anti-frost. It can significantly improve the performance of aluminum foil and has important economic and social benefits. Hydrophobic fin aluminum foil usually uses 1100, 1200, 8011 and other aluminum alloys.

Hydrophobic aluminum foil V&S Hydrophilic aluminum foil
1. Ability to absorb moisture
Hydrophilic aluminum foil is good at adsorbing water molecules in the surrounding environment and has strong wet adhesion. Hydrophobic aluminum foil is not easy to absorb water molecules and has moisture-proof and waterproof properties.
2. Application scope
Hydrophilic aluminum foil is suitable for product packaging that needs to absorb or retain moisture, such as dietary supplements, cosmetics, etc.; while hydrophobic aluminum foil is suitable for product packaging that needs to be moisture-proof and waterproof, such as food, medicine, electronic products, etc.
3. Production process
Since hydrophilic aluminum foil has good adsorption properties, production is difficult and requires a special production process; while hydrophobic aluminum foil has a relatively simple production process.
Performance characteristics of hydrophobic aluminum fins:
1. Hydrophobic performance: The surface of the hydrophobic aluminum fin foil has been specially treated to make it difficult for water to adhere to its surface, thus effectively preventing the formation and accumulation of condensed water.
2. Improve heat exchange efficiency: Due to the hydrophobic performance, a condensed water layer will not form on the surface of the fins, keeping the heat exchange surface of the heat exchanger dry and improving the heat exchange efficiency.
3. Extend the service life: Hydrophobic aluminum fin foil can effectively prevent condensation water from corroding and contaminating the fin surface, thereby extending the service life of the heat exchanger.
4. Energy saving and environmental protection: By improving heat exchange efficiency, hydrophobic aluminum fin foil helps reduce the energy consumption of equipment and achieve energy saving and environmental protection.
