Abstract
The invention relates to a surface treating method of air condition heat emission plates, which comprises (1), using sand injection or dry milling to treat the surface, remove the surface dirt, oxidation layer or present coat to form micro concave-convex structure; (2) using deionized water to wash the heat emission plate to remove surface foreign matters to be dried; (3) using acid or alkali to deeply erode the surface to form stable and clear micro concave-convex structure; (4) using deionized water to wash the heat emission plate and clear the surface to be dried and attain final product. The invention can realize hydrophile effect on the surface, therefore, the water that condensed on the surface in the refrigeration of air conditioner can quickly be distributed and flow into the flow guide tube to avoid accumulation and effectively avoid be injected into the room with wind.
Description
Affiliated technical field
The present invention relates to a kind of metal surface treatment process, especially a kind of process of surface treatment of heat sink of air conditioner.
Background technology
Air-conditioner generally can be divided into window air conditioner and split type air conditioner.Window air conditioner is installed on the window, is the one-piece type air-conditioner of indoor set and off-premises station, and its off-premises station one side is towards outdoor, and indoor set is towards indoor; The indoor set of split type air conditioner and off-premises station then are provided with respectively, and indoor set is installed in indoor, and off-premises station is installed in outdoor.Above-mentioned air-conditioner has the branch of single cooler and cold, hot two-purpose machine again, and the indoor set of cold, hot two-purpose machine has electric heater unit, and this electric heater unit is converted into heat energy with electric energy, and carries out heat exchange by fin and air-supply instrument, heat is blown into indoor.Above-mentioned fin generally is the fin shape of being made by fine aluminium.
Traditional electric heater unit is that it has many defectives with the electrothermal tube heating.At present existing a kind of novel heater, be that a kind of positive temperature coefficient resistor pottery is a ptc material, be characterized in making element with relevant temperature and shape according to different instructions for uses, electric current by the time this pottery will generate heat, when temperature rises to when temperature required, its resistance can increase several thousand to several ten thousand times, electric current by potsherd is reduced, potsherd maintains on the operating temperature all the time, so it has the automatic constant-temperature heating, no superheating phenomenon, the flames of anger, little power consumption, advantage such as safe and reliable.From the above, ptc material has the incomparable advantage of a series of traditional electrical thermal elements, and therefore, the application of ptc material heats to air-conditioning and brought once technological innovation by a stride, and it has solved the many disadvantages that original electrothermal tube heating brings.Ptc material on the above-mentioned air-conditioner is that the resistor ceramic sheet is converted into heat energy with electric energy, heat is dispersed into indoor by fin again.But fin has serious seeping phenomenon when air conditioner refrigerating, and is sprayed onto indoorly with wind-force, and the application in air-conditioning is fatal to this defective to ptc material.The way that addresses this problem at present is by the physical dimension of fin and the gap between the fin are adjusted, but this adjustment is subjected to the restriction of air conditioner room unit structure and free space, can not carry out the improvement of big shape and size to fin, and existing mechanical also can have influence on the radiating effect of fin, so be fundamentally to solve air conditioner room unit this problem of leaking from this angle.
In order more effectively to address the above problem, must carry out hydrophilic treated to wing shape fin.Known this hydrophilic treatment method is to utilize method such as chromate to form layer protective layer on the surface of fin substrate, has formed hydrophilic layer on the surface of this protective layer, and like this, the condensed water that condenses in fin surface is easy to flow away.But protective layer and hydrophilic layer on the fin that this method is handled peel off easily or damage, and still can not fundamentally address the above problem.
Summary of the invention
The objective of the invention is provides a kind of surface treatment process for heat sink of air conditioner in order fundamentally to solve the serious seeping phenomenon of above-mentioned fin when freezing.
To achieve these goals, the method that the present invention adopts sandblast or dry grind process then to adopt acid or alkali to carry out corrosion treatment is carried out specially treated to the surface of fin, change the surface texture of fin, make its surface have excellent hydrophobic property or hydrophily, make air-conditioner when refrigeration, the moisture content that condenses on the fin flows away rapidly on its surface or sprawls rapidly, directly enters mozzle.This processing method comprises following processing step:
The physical method that the 1st step, employing are sandblasted or dry grinded is removed fin surface dirt, oxide layer or existing coating, begins to take shape the micro-bump structure of certain rule in fin surface;
The 2nd step, fin is washed, remove its Superficial Foreign Body with deionized water, and thoroughly oven dry;
The 3rd step, adopt the chemical method that acid or alkali corrode that fin surface is done degree of depth corrosion treatment, make its surface form stable, micro-bump structure clearly;
The 4th step, with deionized water fin is washed once more, clean its surface texture, and thoroughly oven dry, finished product become.
Owing to adopted technique scheme, form many micropores in fin surface, make the surface of fin reach hydrophilic effect, mozzle can be sprawled and flow directly into to the moisture content that condenses upon fin surface when air-conditioner freezes rapidly, and can be at its surface sediment, it is indoor to prevent that effectively ponding is sprayed onto with wind-force; Simultaneously, because the hydrophilic layer that formed by micropore of fin surface is directly to form on the fin substrate, be a part that belongs to heat sink body, so this hydrophilic layer can not produce with fin and peel off phenomenon.
The specific embodiment
Describe the present invention below in conjunction with specific embodiment:
Embodiment 1:
1, at first with the method for sandblasting, the surface of fin is handled, remove fin surface dirt and oxide layer, begin to take shape the micro-bump structure of certain rule in fin surface.
2, with deionized water fin is washed, remove its Superficial Foreign Body, and thoroughly oven dry;
3, be that 10% acid is done degree of depth corrosion treatment to fin surface with concentration, make its surface form stable, micro-bump structure clearly;
4, with deionized water fin is washed once more, clean its surface texture, and thoroughly oven dry;
5, dry, pack.
Embodiment 2:
1, at first uses dry grind process, the surface of fin is handled, remove fin surface dirt and oxide layer, begin to take shape the micro-bump structure of certain rule in fin surface.
2, with deionized water fin is washed, remove its Superficial Foreign Body, and thoroughly oven dry;
3, be that 15% alkali is done degree of depth corrosion treatment to fin surface with concentration, make its surface form stable, micro-bump structure clearly;
4, with deionized water fin is washed once more, clean its surface texture, and thoroughly oven dry;
5, dry, pack.
