Abstract
The utility model provides a heat radiation layer of awaiting radiator, which is formed by a plurality of granules with diameters of 0.05-0.5mm are coated on an awaiting radiator with a prearranged thickness, wherein the heat radiation layer has characteristics of insulation and high thermal conductivity, the total surface area of the granules is larger than the surface area of the awaiting radiator coated with the heat radiation layer, thereby providing better heat radiation effect.
Description
Technical field
The utility model is relevant with heat dissipation technology, more detailed it, be to refer to increase treat the heat-dissipating thing area of dissipation, and then produce a kind of heat radiation coating for the treatment of heat-dissipating thing of better radiating effect by the irregular heat radiation coating of coating layer of surface.
Background technology
In the existing heat dissipation technology, being example with the circuit board, only is to do a radiating treatment for example finned or fan for heat-generating electronic elements usually, or direct precalculated position finned on circuit board, so as to having better radiating effect.
Yet, in the aforesaid existing radiating mode, no matter be finned or fan, all have the high problem of cost of parts, in addition, the machining clearance in the assembling, time also one of consider for cost, moreover finned or fan also can make overall volume become more huge.
The utility model content
Main purpose of the present utility model is promptly providing a kind of heat radiation coating for the treatment of heat-dissipating thing, and it can increase the area of dissipation for the treatment of heat-dissipating thing increasing hardly under the situation treat the heat-dissipating thing height, and then improves radiating effect.
Of the present utility model time a purpose is that a kind of heat radiation coating for the treatment of heat-dissipating thing is being provided, and it only increases by a coating layer, more saves cost than usual way with fin or fan.
For achieving the above object, the technical solution of the utility model provides a kind of heat radiation coating for the treatment of heat-dissipating thing, be to treat to form on the heat-dissipating thing in one between most particle coating predetermined thickness of 0.05～0.5mm by diameter, the heat radiation coating has the characteristic of insulation and high heat conduction, the surface area summation of particle is coated the surface area for the treatment of on the heat-dissipating thing greater than the heat radiation coating, and then can have better radiating effect.
The described heat radiation coating for the treatment of heat-dissipating thing, wherein: the heat radiation coating is materials such as aluminium oxide or oxidized metal.
The described heat radiation coating for the treatment of heat-dissipating thing, wherein: the coating position for the treatment of heat-dissipating thing is to be the plane.
The described heat radiation coating for the treatment of heat-dissipating thing wherein more includes: a fin, with the bottom be sticked the heat radiation coating on.
The utility model still has other advantages except the effect with aforementioned high cooling efficiency:
Can not increase the height for the treatment of heat-dissipating thing when one, the utility model is implemented, this can make treats that heat-dissipating thing keeps splendid application elasticity.
Two, can increase current density: by heat radiation of the present utility model middle level, can fast heat energy be treated to remove on the heat-dissipating thing certainly, treat that the wiring on the heat-dissipating thing promptly can not be subjected to high thermal impact and produce high impedance, the current density that wiring can bear be thereby increases.

Fig. 2 is the side schematic view of the utility model one preferred embodiment;
Fig. 3 is the enforcement state diagram of the utility model one preferred embodiment.
Embodiment
In order to describe structure of the present utility model and characteristics place in detail, lift following two preferred embodiments now and cooperate graphic explanation as back:
See also Fig. 1 to Fig. 2, a kind of heat radiation coating 10 for the treatment of heat-dissipating thing that the utility model first preferred embodiment is provided, mainly be to cover with paint, lacquer, colour wash, etc. predetermined thickness by most alumina particles 11 to treat to form on the heat-dissipating thing 21 in one, be to be example in the present embodiment with a circuit board, the diameter of particle 11 is about 0.15mm in present embodiment, for convenience of description, special in figure, will slightly amplify than actual ratio, heat radiation coating 10 has insulation, and the characteristic of high heat conduction, treat on the heat-dissipating thing 21 even coat comprehensively, also can not cause the short circuit for the treatment of between last circuit of heat-dissipating thing 21 (circuit board) or contact.Wherein, the material of heat radiation coating also can be other oxidized metals, and has the effect of similar high heat conduction, insulation.
Please consult Fig. 1 again, as seen from the figure, the surface area of particle 11 is spherical exposing, so its surface area summation is to double at least to treat heat-dissipating thing 21 lip-deep applied areas, that is, be coated with the area of dissipation that heat radiation coating 10 produced and can have had more at least one times by more original area of dissipation.
If with the circuit board is example, with regard to the heat radiation of circuit board itself, its wiring (copper platinum) that only can see through metal material is dispelled the heat, therefore in fact the true area of dissipation on circuit board generally can be less than half of its whole surface area, and actual area of dissipation of the present utility model is at least greater than treating the i.e. twice of (circuit board) area of heat-dissipating thing, in other words, area of dissipation of the present utility model is promptly at least greater than more than four times of the original actual area of dissipation of circuit board; This shows that the utility model can significantly improve area of dissipation, and relend high-termal conductivity, can significantly improve radiating efficiency by heat radiation coating itself; And, by the insulating properties of heat radiation coating, can make directly contact circuit plate and can not getting an electric shock of personnel, have better fail safe,
The heat-dissipating thing for the treatment of of the present utility model does not exceed with circuit board, is that example only is for convenience of explanation with the circuit board among the embodiment, is not in order to restriction this case scope; Other are as motor shell surface, lamp surface ... or the like electro-heat equipment, all can implement the utility model.
Please consult Fig. 3 again, the utility model also can cooperate a fin 31, adheres on the heat radiation coating 10 with its bottom, by the high-termal conductivity of heat radiation coating 10, can will treat that the heat energy on the heat-dissipating thing 21 is directed on the fin fast, so as to producing better heat-conducting effect.
The utility model still has other advantages except the effect with aforementioned high cooling efficiency:
Can not increase the height for the treatment of heat-dissipating thing when one, the utility model is implemented, this can make treats heat-dissipating thing Keep splendid application elasticity.
Two, can increase current density: by radiating middle layer of the present utility model, can be fast with heat Can certainly treat to remove on the heat-dissipating thing, treat that the wiring on the heat-dissipating thing namely can not be subjected to high heat affecting and produce height Impedance, the current density that wiring can bear are thereby increase.
