Air conditioner aluminum foil tape is mainly used in the production of heat exchanger fins, such as air-conditioning condensers and evaporators, refrigerator frost-free evaporators/finned evaporators, commercial refrigerator condensers and evaporators, automotive air-conditioning condensers and evaporators, etc. Generally, the coated one is hydrophilic aluminum foil.
The aircon aluminum foil without any anti-corrosion coating is silver in color. At present, the fins of many air conditioners have anti-corrosion coatings, many of which are blue or green, of which the purpose is to improve the corrosion resistance of the fins.
The hydrophilic layer can make the moisture condensed on the heat exchange fins to spread out and flow down the surface, so as to avoid affecting the ventilation of the heat exchanger due to the condensation of water droplets between the heat exchange fins, thereby increasing the heat exchange rate by 5%.
The surface of the aluminum foil coated with a hydrophilic coating has a strong affinity for water, and the condensed water diffuses quickly on the fins, so the ventilation effect is good when the air conditioner is running. The index to measure hydrophilicity is called hydrophilic angle. For non-hydrophilic aluminum foil, the smaller the sheet distance, the larger the pressure drop ratio, and the lower the heat transfer efficiency of the evaporator.
For hydrophilic coated fins, the smaller the contact angle, the lower the pressure drop ratio, and the better the heat transfer efficiency of the evaporator. The hydrophilic film will age and oxidize over time, and the hydrophilic performance will obviously decline, causing condensed water to form during the cooling process and blocking the circulating air duct, which finally causes the cooling effect to decay year by year.
The production process of the coated foil for aircon requires the aluminum foil to have a good shape, which is a prerequisite for the production of coated aluminum foil. The unit to measure the plate shape is I. General coating production equipment requires a plate shape within 20-40I. If it is greater than this value, a tension straightening system needs to be added in front of the coating equipment.
Generally, the running route of coating equipment is long, and there are many processing procedures and guide rollers. Therefore, if the tension straightening system is not equipped, once the plate shape is not good, it is easy to fold during operation, resulting in failure to produce. Haomei Aluminum has mature processing technology. Welcome to leave message below to tell us which kind of air conditioner aluminum foil you need.
