Embodiment
In order further to understand the present invention, below in conjunction with embodiment the preferred embodiments of the invention are described, but should be appreciated that the just restriction for further specifying the features and advantages of the present invention rather than patent of the present invention being required of these descriptions.
The invention provides a kind of waterproof workpiece, comprising: metal body;
Has at least one micropore that under first condition, forms on the described metal body, wherein, carry out the gas communication of described metal body both sides and/or gas exchange by described micropore, simultaneously, liquid can't be by described micropore from a side flow of described waterproof workpiece to opposite side.
The prior art of comparing, as shown in Figure 2, waterproof workpiece provided by the invention is to be made of metal body 1 and at least one micropore 2 of being arranged on the described metal body, described metal body preferably is made of one deck metal forming at least, described metal forming is preferably light weight and the good metal formings of heat conduction such as aluminium foil well known to those skilled in the art, silver foil, iron foil or magnadure paper tinsel, and the present invention is aluminium foil more preferably.According to the present invention, the thickness of described waterproof workpiece is preferably 0.1～0.15nm, more preferably 0.12～0.15mm.The diameter of described micropore is preferably 0.03～0.15mm, more preferably 0.045～0.1mm.The number of micropore of the present invention is relevant with the size of waterproof workpiece heat dissipation region, and the present invention does not do restriction, and the distance between the described micropore is preferably 0.1～0.5mm, and the too small meeting of little distance between borehole causes the waterproof workpiece in use to be out of shape.According to the present invention, the number of described metal forming and thickness the present invention do not do restriction.The waterproof workpiece that embodiments of the invention provide, depress at room temperature, standard atmosphere, sprinkle liquid on described waterproof workpiece, described liquid is under capillary effect, gather into some drops in described waterproof workpiece surface groups, the drop of diameter minimum is greater than the micropore of diameter maximum in described at least one micropore in the described drop, for example, and greater than 0.15mm.When satisfying as above condition, described liquid can't be by micropore from a side flow of waterproof workpiece to opposite side.
According to the present invention, as shown in Figure 2, be preferably included in the watertight composition 3 that is solidify to form by water-repellent paint on the described metal body.Described micropore runs through described watertight composition.Described water-repellent paint is preferably fluorine-containing water-repellent paint, more preferably teflon coating.The teflon coating good water-proof effect, the waterproofing layer thickness after the curing is thin, can satisfy the frivolous requirement of waterproof workpiece.Because in the middle of practical application, the waterproof surface of the work may be under pressure and the impact of temperature, cause the micropore on the waterproof workpiece to enlarge, liquid can flow through micropore, so the present invention applies tetrafluoroethene coating at the waterproof workpiece, increase the surface tension of waterproof surface of the work, make the surface tension at micropore place larger, the probability that liquid flows through micropore is less.In other words, the liquid drop probability that spills lower rear formation becomes large.According to the present invention, the concentration of the middle polytetrafluoroethylene of described polytetrafluoroethylene water-repellent paint is 0.1wt%～0.2wt%.Described waterproofing layer thickness is 20～40nm, more preferably 25～30nm.
According to the present invention, being coated with waterproof workpiece behind the water-repellent paint, the surface contact angle of one side of watertight composition is arranged is 100～110 °.Surface contact angle is the performance parameter that characterizes body surface tension force, one liquid is dripped on the level and smooth uniformly surface of solids, if do not sprawl, then will form a balance drop, its shape is determined by solid-liquid-gas three phase intersection any two alternate angles, usually the angle to gas-liquid interface is equilibrium contact angle through drop inside from solid liquid interface to be defined in the three-phase intersection, represents with θ.The pass of contact angle and three interfacial tensions is equation as follows:

a, W
iLarger with S, surface tension is less, and wetability is better, and θ is larger, and surface tension is larger, and wetability is less, drop (L) is placed on the ideal plane (S), if having one to be gas mutually, then contact angle be liquid-vapor interface pass through liquid and with the folded angle of solid-liquid interface.Be illustrated in fig. 1 shown below.So the surface contact angle of waterproof workpiece provided by the invention is 100～110 °, the droplet profile that is sprinkled upon the waterproof surface of the work is similar to oblate spheroid, can be not wetting, and because the diameter of described micropore is far smaller than the plane width of waterproof workpiece, so the surface tension at micropore place is similar to the surface tension of described waterproof workpiece, the micropore place still has good water proofing property on the described waterproof workpiece provided by the invention, and liquid can't be by described micropore from a side flow of described waterproof workpiece to opposite side.
According to the present invention, the preparation method of described waterproof workpiece is preferably:
A) provide metal forming, and at described metal body surface-coated water-repellent paint;
B) under first condition, form micropore according to the micropore number that sets in advance and diameter in described metal forming, obtain the waterproof workpiece.
According to the present invention, described first condition is preferably laser engraving, and during described laser engraving, the frequency of laser pulse is that 1050～1070nm laser power is 180～240W.
Waterproof workpiece provided by the invention is provided with micropore at metal body, owing to be the metal surface, surface tension is larger, so the liquid sprinkle can not tile from the teeth outwards, but be agglomerated into drop, described micropore is arranged on the metal body, so the surface tension of micropore is still greater than drop, so liquid can't be by micropore from a side flow of waterproof workpiece to opposite side.Can either have good waterproof effect, not be used in again the waterproof membrane that binding agent is set on the metal body and bonds with binding agent, satisfy the requirement frivolous to the waterproof workpiece.In addition, because inapplicable waterproof membrane, so reduced the cost of waterproof workpiece.For can better reaching the effect that liquid is agglomerated into drop, can also be on metal body, specifically described at least one micropore place applies water-repellent paint.
The present invention also provides a kind of electronic equipment, comprising:
Electronic devices and components, described electronic devices and components are used for supporting the operation of described electronic equipment, produce heat;
