Brief Introduction on Air Conditioner Foil by Diverse Kinds

At present, air conditioner is gradually creating in the path of miniaturization, higher efficiency and lengthy service life. Whereas, air-conditioner foil applying higher grade aluminum can also be building with a trend of ultrathin and high strength. In 80s, 20th century, Air-Conditioner Foil thickness is about 0.15 to 0.20ram, though these days, its thickness is involving 0.09 to 0.15mm. In addition to, as a way to enhance air conditioner service life, decrease energy consumption, ideal ventilation quality and boost refrigeration effect, Coated Aluminum Coil with numerous functions is successively exploited by Aluminum Coil Suppliers, commonly, erosion resistant variety, facial hydrophilic kind, facial hydrophobic sort, mould proof type, self-lubrication type and other people. Under, let’s find out about them in detail.

Form one, non-coating aluminum foil

Non-coating aluminum foil refers to aluminum foil of hardening aluminum following thermal annealing rolling with surface unprocessed in any forms including creating in to the aluminum foil reflector. It has been extensively applied in air conditioner heat exchange plate for about tens of years by lots of nations. Even at present, in quite a few developed countries, there is nonetheless about 50 % of heat exchange plates apply non-coating aluminum foil. For aluminum foil China, the application price is about 60 %.

Kind two, coating aluminum foil

So called coating aluminum foil could be the aluminum foil with specific unique function right after facial retreatment around the basis of non-coating aluminum foils, some thing like painted aluminum coil or coated aluminum coil. In Japan and Germany such countries rapidly developed in related technologies, coating aluminum foil has been applied to get a history of more than 15 years. So for aluminum foil cost, it's more reasonable compared with that of other aluminum components like aluminum wafer.

Type 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 item, some like aluminium foil roll within the type of One-zero foil and Double-zero foil is appropriate for regions of bad situation which can definitely boost air conditioner service life. At the same time, on account of enhanced erosion resistance overall performance, it tremendously reduces facial erosion power improvement and hence perfects ventilation quality and purifies air within the room.

Sort four, hydrophilic aluminum foil

Hydrophilic aluminum foil has a great deal powerful hydrophilcity on the surface which is decided by the angle dimension created just after water sticks on aluminum foil surface, the smaller sized the superior. Normally speaking, angle dimension smaller than 35゜ indicates hydrophilcity. Hydrophilic aluminum foil is mainly applied in air conditioner condenser. The primary function is to make water drops condensed on heat exchanger by moisture in heat air very easily spread and flow downward along the plate, in particular brushed aluminum plate, so to prevent water drops amongst heat exchange plates ‘bridging’ which impacts the ventilation impact. It might therefore to enhance the heat exchanging efficiency and save energy within the condition of equal refrigerating capacity. At present, hydrophilic aluminum foil in the market still has substantially high erosion resistance performance which superior optimize the air conditioner.

Kind five, hydrophobic aluminum foil

Hydrophobic aluminum foil, also named water repellency aluminum foil has the facial functionality contrary to hydrophilic aluminum foil. Its contacting angle created by condensed water sticking on welding aluminum foil surface is generally bigger than 75゜. The larger angle, the much better water repellency efficiency it possesses. The final aim of applying hydrophobic aluminum is same to that of hydrophilic aluminum foil that is to help keep condensed water from staying between heat exchange plates. What’s the difference is that hydrophobic aluminum foil reaches the aim of having 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 simply sliding water drops

Variety six, self-lubrication aluminum foil

Air conditioner heat exchange plate commonly 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 need to add lubrication oil in the punching approach and applies pre-treating membrane on aluminum foil surface for the replacement in punching. Because there's needless of specially adding lubrication oil, it thereby saves subsequent procedures of trichloro ethylene washing and drying. Within this case, it really is also widely applied in embossed aluminum sheet and aluminum coils.

Kind 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 main function would be to avoid heat exchange plate from getting surface moulding for lengthy time usage or storage. Thereby, it certainly improves air conditioner ventilation top quality, prevents abnormal taste from generation and successfully perfect indoor environment. By the way, aluminum foil container from meals packaging aluminium also applies the mould proof aluminum foil for the peculiar functionality.
