Brief Introduction on Air Conditioner Foil by Distinctive Sorts

At present, air conditioner is steadily developing within the direction of miniaturization, higher efficiency and long service life. Whereas, air-conditioner foil applying higher grade aluminum can also be developing with a trend of ultrathin and high strength. In 80s, 20th century, Air-Conditioner Foil thickness is about 0.15 to 0.20ram, though today, its thickness is in between 0.09 to 0.15mm. Besides, to be able to boost air conditioner service life, reduce energy consumption, best ventilation excellent and improve refrigeration impact, Coated Aluminum Coil with numerous functions is successively exploited by Aluminum Coil Suppliers, typically, erosion resistant variety, facial hydrophilic sort, facial hydrophobic type, mould proof form, self-lubrication variety and others. Beneath, let’s learn about them in detail.

Kind 1, non-coating aluminum foil

Non-coating aluminum foil refers to aluminum foil of hardening aluminum right after thermal annealing rolling with surface unprocessed in any forms including establishing in to the aluminum foil reflector. It has been widely applied in air conditioner heat exchange plate for about tens of years by several countries. Even at present, in numerous created countries, there is certainly nevertheless about 50 % of heat exchange plates apply non-coating aluminum foil. For aluminum foil China, the application price is about 60 percent.

Form two, coating aluminum foil

So known as coating aluminum foil would be the aluminum foil with certain special function after facial retreatment around the basis of non-coating aluminum foils, a thing like painted aluminum coil or coated aluminum coil. In Japan and Germany such nations quickly created in related technologies, coating aluminum foil has been applied for any history of over 15 years. So for aluminum foil value, it can be a lot more reasonable compared with that of other aluminum parts like aluminum wafer.

Variety 3, erosion resistant aluminum foil

Erosion resistant aluminum foil has an erosion resistant protection layer on the surface. Air conditioner heat exchange plate some manufactured from such solution, some like aluminium foil roll within the form of One-zero foil and Double-zero foil is appropriate for regions of terrible condition which can naturally boost air conditioner service life. Simultaneously, resulting from enhanced erosion resistance functionality, it considerably reduces facial erosion power improvement and hence perfects ventilation quality and purifies air in the room.

Kind four, hydrophilic aluminum foil

Hydrophilic aluminum foil has much powerful hydrophilcity on the surface that is decided by the angle dimension developed just after water sticks on aluminum foil surface, the smaller sized the better. Typically speaking, angle dimension smaller than 35゜ indicates hydrophilcity. Hydrophilic aluminum foil is mostly applied in air conditioner condenser. The primary function would be to make water drops condensed on heat exchanger by moisture in heat air very easily spread and flow downward along the plate, specially brushed aluminum plate, so to prevent water drops among heat exchange plates ‘bridging’ which impacts the ventilation effect. It can thus to improve the heat exchanging efficiency and save energy within the condition of equal refrigerating capacity. At present, hydrophilic aluminum foil within the industry nevertheless has a great deal higher erosion resistance efficiency which improved optimize the air conditioner.

Sort five, hydrophobic aluminum foil

Hydrophobic aluminum foil, also named water repellency aluminum foil has the facial overall performance contrary to hydrophilic aluminum foil. Its contacting angle created by condensed water sticking on welding aluminum foil surface is generally larger than 75゜. The bigger angle, the much better water repellency performance it possesses. The final aim of applying hydrophobic aluminum is identical to that of hydrophilic aluminum foil that is to maintain condensed water from staying between heat exchange plates. What’s the distinction is that hydrophobic aluminum foil reaches the aim of finding rid of condensed water amongst heat exchange plates by enlarging contacting angle among condensed water and heat exchange plate as to prompt condensed water create into conveniently sliding water drops

Sort six, self-lubrication aluminum foil

Air conditioner heat exchange plate generally firstly applies lubrication oil on the surface, then punching flanging and ultimately use trichloro ethylene to wash off the lubrication oil. For the cause that trichloro ethylene is harmful to human body, there correspondingly emerges self-lubrication aluminum foil. Self-lubrication aluminum foil, as its name implies, doesn’t want to add lubrication oil in the punching procedure and applies pre-treating membrane on aluminum foil surface for the replacement in punching. Since there is needless of specially adding lubrication oil, it thereby saves subsequent procedures of trichloro ethylene washing and drying. Within this case, it truly is also broadly applied in embossed aluminum sheet and aluminum coils.

Sort seven, mould proof aluminum foil

Mould proof aluminum foil, largely household aluminum foil is primarily applied in indoor unit a part of air conditioner. Its key function should be to avoid heat exchange plate from finding surface moulding for long time usage or storage. Thereby, it of course improves air conditioner ventilation high-quality, prevents abnormal taste from generation and proficiently perfect indoor environment. By the way, aluminum foil container from meals packaging aluminium also applies the mould proof aluminum foil for the peculiar performance.
