Alu Strip for HVAC Bare Finstock

Alu strip for HVAC bare finstock radiators are the most widely used heat exchange equipment in gas and liquid heat exchangers. Any cold heat exchanger that is equipped with fins on the heat exchange tube to increase the heat dissipation area can be summarized as a "finned tube radiator". Finned tube radiators can be divided into winding fin type; string fin type; welding fin type; rolled fin type according to the structure of the fin. Commonly used finstock materials are steel; stainless steel; copper; aluminum, etc.

Finned tube radiators are generally used for heating or cooling air, and have the characteristics of compact structure and large unit heat exchange area. It is widely used in textile, printing and dyeing, petroleum, chemical industry, drying, electric power and other fields. The most widely used finned radiator is the aluminum finned tube, which takes advantage of the high-efficiency thermal conductivity of aluminum strip. At present, the main alloy grades of aluminum strip for air conditioning fins on the market are 8011, 1060, 3102, 1100, 8006 and other aluminum alloys, and the state is mainly O, H22 and H26.
 
Besides of alu strip for HVAC bare finstock, hydrophilic foil is coated with an anticorrosive inorganic coating and a hydrophilic organic coating on the surface of the aluminum strip foil. It also has anti-corrosion, anti-fungal and other functions. Compared with bare aluminum strip, its cooling efficiency is increased by about 5%. It is a more ideal heat dissipation material for air conditioners. Hydrophilic aluminum strip foil account for more than 80% of the total aluminum foils for air conditioning. Inverter air conditioners and export air conditioners mostly use hydrophilic foils, while domestic low-end air conditioners, window machines, and automobile air conditioners mostly use plain foils.
