Heat exchanger aluminum fin stock is a material used to make heat exchangers, usually made of aluminum foil. The main function of aluminum fin stock is to increase the surface area of the heat exchanger and improve the heat transfer efficiency. Heat exchanger aluminium fin stock is mostly made of aluminum alloy, among which 8011 aluminum alloy is widely used due to its outstanding performance advantages and high cost performance. 8011 aluminum alloy has the characteristics of low density, easy processing, good thermal conductivity, odorless, environmental protection and low price, and it is not easy to deform under long-term cold and hot conditions and has a long service life.
According to different manufacturing processes and uses, heat exchanger aluminum fin stock can be divided into the following categories:
Bare aluminum fin stock material: smooth surface and beautiful appearance, usually used in occasions requiring beautiful appearance.
Pre-coated aluminum fin stock material: the surface is specially coated with a hydrophilic coating to improve the heat dissipation efficiency, which is suitable for occasions with high requirements for heat dissipation effects.
Performance characteristics of heat exchanger aluminum fin stock:
– Thermal conductivity: Aluminum foil has good thermal conductivity, can quickly transfer heat from one side to the other, and improve heat exchange efficiency.
– Hydrophilicity: In applications such as air conditioning, hydrophilic aluminum foil is used for heat exchanger fins, which can effectively eliminate the “water bridge” phenomenon between fins, reduce ventilation resistance and noise, and reduce energy consumption. The contact angle of water droplets on the surface of hydrophilic aluminum foil is small, and the water droplets can quickly diffuse and flow out along the surface to avoid the formation of water bridges between fins.
– Corrosion resistance: The surface of aluminum foil is specially treated, such as coating treatment, to improve its corrosion resistance and extend its service life.
– Processability: Aluminum foil is easy to stamp and form, suitable for large-scale production, and the cost is relatively low.
Heat exchanger aluminum fin stock is widely used in many fields, including:
– Air conditioning refrigeration: As an important component of the condenser and evaporator of the air conditioning system, it realizes the heating or cooling of indoor air.
– Industrial cooling: In the production process of chemical, petroleum, pharmaceutical and other industries, it is used to heat or cool various fluids.
– Refrigeration equipment: Such as condensers and evaporators in refrigeration equipment such as refrigerators and freezers.
– Other fields: There are also applications in fields such as food processing, electricity and textiles.
