Description
Technical field
The present invention relates to a kind of manufacture craft of hydrophily epithelium of aluminium radiator fin.
Background technology
In air conditioner, due to remarkableization of the problem such as global warming and energy shortage, the raising of the performance of the high efficiency of air conditioner and miniaturization etc. requires constantly surging.For this requirement, in the heat exchanger of air conditioner, due to excellences such as thermal conductivity, processability, corrosion resistances, aluminium is widely used.And, in order to carry out heat exchange efficiently, and, in order to make spaces compact, form the structure that aluminum heat radiation sheet is set with narrow spacing parallel arranging in a heat exchanger.When air-conditioner operation, when the temperature on fin material surface is below the dew point of air, be attached to the condensed water aggegation on fin material surface, adjacent fin material can be made to block each other.Now, if the hydrophily on aluminum heat radiation sheet surface is low, then the contact angle of water becomes large, and therefore, the condensed water of attachment is formed hemispherical, makes the blocked state of fin worsen further.Consequently, hot-swap feature is obstructed, or condensed water is outer etc. to air conditioner because blast disperses, and these problems are always known.For this reason, by the mineral-type surface conditioning agent at the surface of aluminum heat radiation sheet coating waterglass etc., hydrophily is given to fin material surface thus.But they easily adsorb the smell component in environment, when operating beginning, smell component departs from generation peculiar smell.
In order to address this is that, in the technology that patent document 1 is recorded, form chromate epithelium on the surface of aluminium, form alumina sol epithelium thereon and giving hydrophily.In addition, as the technology that patent document 2 is recorded, also has the method using with hydrophilic resin the organic surface conditioning agent being principal component.The surface conditioning agent of acrylic resin can be used as the organic surface conditioning agent taking hydrophilic resin as principal component.
But even if the coating using these to form, due to used environment, various pollution attachment causes original characteristic to be lost.During the attachments such as the oil droplet particularly occurred when nursing one's health, its impact significantly.In the pollution of attachment, comparatively speaking aldehydes etc. are owing to having solubility to glassware for drinking water, therefore be naturally dissolved in condensed water, but grease classes (oil droplet produced when floor wax or conditioning) etc. are owing to substantially can not be dissolved in water, as long as so be attached to film coated surface and would not easily come off.In order to make grease class be not easy attachment, also consider to have the surface tension of film is reduced to extremely low method, but surface becomes repellency simultaneously, the pressure loss becomes large.In addition, also consider to have to make the attachment material of wet goods hold caducous method by being mixed into the material with interfacial activity effect in film in advance.But, in the method, its action deprivation after the whole stripping of interface active agent.
In order to address this is that, even if Patent Document 3 discloses pollutants such as being attached with grease, polluter is scrubbed, the coating composition that in consequently long-time, hydrophily also can not reduce and the technology of radiator fin for heat exchanger by condensed water during cooling operation.Specifically, be containing the polymer body comprising sulfonic acid alkali metal salts in the film of fin surface.The polymer body comprising sulfonic acid alkali metal salts due to the compatibility with grease class extremely low, so grease class is difficult to stick, also excellent with the compatibility of water in addition.In patent document 3, by the effect of this sulfonic acid alkali metal salts, scrub polluter (grease class) by condensed water.
