Due to its low density, good thermal conductivity, easy processing, odorless, environmental protection and low price, aluminum foil is used to make heat transfer fins for air conditioning heat exchangers. Today, its aluminum foil thickness is only between 0.09 and 0.15mm.
At present, the air-conditioning foil is generally divided into plain aluminum foil and coated aluminum foil, which are respectively used in low-end split air conditioners and high-end inverter air conditioners.
Name | Production process | Features | Application scope |
Plain aluminum foil | Aluminum foil without any treatment on the surface after rolling and annealing | Simple process and low price | Low-end split air conditioner outdoor unit and window unit |
Coated aluminum foil | Coat both sides of the plain foil with anti-corrosion coatings and hydrophilic coatings of various quality requirements | The heat exchange efficiency is increased by about 5%, which can save energy, save materials, reduce the volume of the air conditioner, and extend the service life. | Inverter, high-end air conditioner and air conditioner for export |
Specifically, there are plain aluminum foil, dark blue hydrophilic aluminum foil, blue hydrophilic aluminum foil, dark golden hydrophilic aluminum foil, black epoxy resin hydrophilic aluminum foil, white inorganic hydrophilic aluminum foil, green hydrophobic aluminum foil, light green hydrophobic aluminum foil, golden hydrophilic aluminum foil, black acrylic resin hydrophilic aluminum foil, anti-corrosion aluminum foil,etc.
Which types of aluminum foil is used to process the heat exchange fins needs to be customized according to actual needs and functional requirements, such as whether to be hydrophilic, hydrophobic, and anti-corrosive.
In addition, the thickness of the fins and the processing techniques of the fins, such as holes distance and corrugation, are also related to the energy efficiency requirements of specific fin heat exchangers. Welcome to leave message below to inquire what you need.
