Introduction of air conditioner aluminum foil

Air conditioner aluminum foil is a material used to make air conditioner heat exchangers. Its main features are light and thin, good thermal conductivity, and corrosion resistance. Due to its good thermal conductivity, it can make the air flow fully in the heat exchanger, so as to achieve better cooling or heating effect.

According to the thickness, it can be divided into thin plate and medium plate. The GB/T3880-2006 standard stipulates that the thickness below 0.2 mm is called aluminum foil.

Air conditioners are gradually developing in the direction of miniaturization, high efficiency and long life. The air-conditioning heat exchange fins are also correspondingly developed in the direction of ultra-thin and high-strength. In the 1980s, the thickness of the heat exchanger fins was 0.15-0.2mm, but now the thickness is only between 0.09 and 0.15mm.

The alloy grades of aluminum foil for heat exchange fins mainly include 1100, 1200, 8011, 8021, 8079, etc. From the point of view of use, air conditioners have no strict requirements on the chemical composition of aluminum heat exchanger fins. Which alloy to choose mainly depends on the final mechanical properties that the material can achieve. For example, it is easier to roll the 1100 aluminum alloy with higher purity, but it is more difficult for the 8011 alloy.

The role of aluminum foil in air conditioning and refrigeration

Aluminum foil plays a very important role in air conditioning refrigeration. It is used in evaporators and condensers of air conditioners. Specifically, aluminum foil is used to make the shells and internal piping of evaporators and condensers. Aluminum foil is a very good heat-conducting material, which can help the refrigerant absorb and release heat quickly.

Aluminum foil also has good corrosion resistance. During the cycle of the refrigerant, the refrigerant will come into contact with the aluminum foil. If non-corrosion-resistant materials are used, the refrigerant will corrode the pipes and cause leakage, causing the air conditioner to lose its cooling effect. Aluminum foil has good corrosion resistance, which can effectively prevent this from happening.

In addition, aluminum foil also has good strength and toughness. When making evaporators and condensers, aluminum foil needs to be bent into different shapes, so it needs to have certain toughness and strength.

In short, aluminum foil plays a very important role in air conditioning and refrigeration. It not only helps the refrigerant absorb and release heat quickly, but also has good corrosion resistance, strength and toughness. Therefore, When we choose an air conditioner, we need to pay attention to the materials used, especially the materials of the evaporator and condenser, so as to ensure the cooling effect and service life of the air conditioner.

Classification of air conditioner aluminum foil

Air conditioner aluminum foil can be divided into 7 categories according to its processing technology and performance characteristics:

Non-coated aluminum foil

Uncoated aluminum foil refers to aluminum foil that has been rolled and annealed without any form of surface treatment. 10 years ago in our country, and about 15 years ago in foreign countries, the aluminum foil used for air-conditioning heat exchangers was all non-coated aluminum foil. Even at present, about 50% of the heat exchangers used in foreign developed countries are still non-coated aluminum foils, while in our country, this ratio is about 60%.

Coated aluminum foil

The so-called coated aluminum foil is to re-treat the surface of non-coated aluminum foil to make it have some special function. In Japan, Germany and other countries with rapid technological development, the use of coated aluminum foil has a history of more than 15 years. In my country, the use of coated aluminum foil does not exceed 10 years.

Corrosion-resistant aluminum foil

The surface of corrosion-resistant aluminum foil products has a certain anti-corrosion protective layer. The air-conditioning heat exchanger made of this product can be used in relatively harsh areas and can significantly increase the service life of the air-conditioning. At the same time, due to the improvement of the corrosion resistance of the heat exchange fins, the generation of surface corrosion powder is greatly reduced, thereby improving the ventilation quality and purifying the air in the air-conditioning room.

Hydrophilic aluminum foil

The surface of hydrophilic aluminum foil has strong hydrophilicity. The hydrophilic performance is determined by the angle formed by water sticking to the surface of the aluminum foil. The smaller the angle a, the better the hydrophilic performance, and vice versa, the worse the hydrophilic performance. Generally speaking, angle a is less than 35°. That is, it belongs to the hydrophilic property. Hydrophilic aluminum foil is generally used on condensers of air conditioners.

Aluminum Hydrophilic Foil

Aluminum Hydrophilic Foil

Its main function is to make the moisture in the hot air easy to spread and flow down the sheet when it condenses into water droplets on the heat exchange sheet. This can avoid affecting the ventilation effect of the heat exchanger due to the “bridge” of water droplets between the heat exchange fins, thereby improving the heat exchange rate of the air conditioner and saving electricity under the same cooling capacity.

At present, the general hydrophilic aluminum foil on the market not only has good hydrophilicity on the surface, but also has high corrosion resistance, so that the performance of the air conditioner is more optimized.

Hydrophobic aluminum foil

Hydrophobic aluminum foil is also called water-repellent aluminum foil, and its surface properties are just the opposite of those of hydrophilic aluminum foil. That is to say, when the condensed water condenses on the surface of the aluminum foil, the contact angle with the aluminum foil is relatively large, generally 75°. above. The larger the angle, the better the water repellency. The ultimate purpose of using hydrophobic aluminum foil is the same as that of hydrophilic aluminum foil, that is, to prevent condensed water from remaining between the heat exchange fins. The difference is that the hydrophobic aluminum foil achieves the purpose of removing the condensed water between the heat transfer fins by increasing the contact angle between the condensed water and the heat transfer fins, so that the condensed water forms water droplets that are easy to slide off.

Self-lubricating aluminum foil

In the process of processing the air-conditioning heat exchange fins, lubricating oil is generally added to the surface first, then punched and flanged, and finally the lubricating oil is washed away with trichlorethylene. Since trichlorethylene is harmful to the human body, in order to reduce this process, a self-lubricating aluminum foil was produced accordingly. Self-lubricating aluminum foil, as the name suggests, does not need to add lubricating oil separately during punching, and the lubrication during punching is borne by the pre-treated film on the surface of the aluminum foil. Since there is no need for special lubricating oil, the subsequent trichlorethylene cleaning and drying processes are also omitted.

Mildew proof aluminum foil

Anti-mildew aluminum foil is mainly used in the indoor unit of the air conditioner. Its main function is to prevent the surface of the heat exchanger from becoming moldy due to use or storage for a long time, thereby significantly improving the ventilation quality of the air conditioner and preventing abnormal odors. Improve the environment in the air-conditioned room.
