Description
Technical field
The present invention relates to a kind of autologous heat loss through radiation structure, particularly relate to a kind of autologous heat loss through radiation structure by having the heat loss through radiation layer improving or promote pyrotoxin generation natural radiation heat dissipation itself in pyrotoxin outer setting one.
Background technology
Existing mobile device (as slim pen electricity, flat board, wisdom mobile phone etc.) along with arithmetic speed faster, the heat that its internal calculation performance element semiconductor chip produces also significantly promotes relatively, and it can prerequisite easy to carry be considered down to have again, this kind of device more does more thinning, in addition described mobile device is for can prevent foreign matter and aqueous vapor from entering inside, these mobile devices are except the providing holes of earpiece holes or connector, have very less and form convection current in open aperture and outside air, therefore because of under the innate factor of thinning, the heat that these mobile devices inside produce because of calculation execution unit and battery cannot outwardly be discharged fast, and because the inside of mobile device is confined space, be difficult to produce heat loss through convection, and then be easy to the facts such as mobile device inside generation accumulated heat or heat build-up etc., have a strong impact on the operating efficiency of mobile device or produce the problems such as heat, serious then make semiconductor chip or the excessive accumulated heat of battery and affect the situation of mobile device task performance or serious heating.
Moreover, owing to there being the problems referred to above, also have and be present in this kind of mobile device inside passive heat radiation element is set: such as hot plate, temperature-uniforming plate, the passive heat dissipation element such as radiator carries out antipyretic to the computing unit chip such as changing, but still be required to design the reason of thinning due to mobile device, the space of this device inside is caused to be restricted and narrow, therefore the heat dissipation element be arranged in this space certainly will be reduced to ultra-thin dimensional thickness, can be arranged in narrow limited inner space, but along with the hot plate of size-constrained reduction, temperature-uniforming plate, then the capillary structure of its inside and steam channel are more because be arranged to ultra-thin requirement also identical limited reduction, cause and make these hot plates, temperature-uniforming plate is had a greatly reduced quality in the heat conducting operating efficiency of entirety, cannot effectively reach heat radiation usefulness, therefore when the internal compute unit power of mobile device is too high, existing hot plate, temperature-uniforming plate all effectively cannot carry out antipyretic or heat radiation because tackling it, therefore how to propose effectively to separate thermal means, then the technology primarily improved at present for those skilled in the art in narrow confined space.
Summary of the invention
Therefore, for effectively solving the problem, main purpose of the present invention is to provide a kind of by having in pyrotoxin outer setting one the heat loss through radiation layer promoting autologous heat loss through radiation usefulness, so as to increasing the autologous heat loss through radiation structure of the heat dissipation of pyrotoxin.
For reaching above-mentioned object, the invention provides a kind of autologous heat loss through radiation structure, comprising: a pyrotoxin, in this pyrotoxin outside, at least side forms a heat loss through radiation layer.
The outside material of described pyrotoxin is that ceramic material or metal material are wherein arbitrary.
Described pyrotoxin is that a battery or semiconductor element or IC chip are wherein arbitrary.
Described heat loss through radiation layer be a kind of loose structure or how rice structure or porous ceramic structure or porousness graphite-structure wherein arbitrary.
Described heat loss through radiation layer is by differential arc oxidation (Micro Arc Oxidation, or electricity slurry electrolytic oxidation (Plasma Electrolytic Oxidation MAO), PEO), anodic spark deposition (AnodicSpark Deposition, ASD), spark deposition anodic oxidation (Anodic Oxidation by SparkDeposition, ANOF) wherein arbitrary side at this pyrotoxin forms cellular structure.
Described heat loss through radiation layer is for hitting produced concaveconvex structure by pearl.
Described heat loss through radiation layer is that the color of black or sub-black or dark system is wherein arbitrary.
Described heat loss through radiation layer is that a kind of high radiation ceramic structure or high-hardness ceramic structure are wherein arbitrary.
Described heat loss through radiation layer is by attach and printing and coating are wherein arbitraryly formed at pyrotoxin on the surface.
The present invention is mainly through at least at pyrotoxin outer surface arranging one and have the heat loss through radiation layer improving autologous heat loss through radiation usefulness in side, make the high efficiency heat loss through radiation efficiency energy of this heat loss through radiation layer, although the effect of natural radiation heat loss through convection still can be had by being arranged at pyrotoxin in airtight accommodation space, significantly increase the heat dissipation of pyrotoxin entirety whereby.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
Characteristic on above-mentioned purpose of the present invention and structure and fuction thereof, is explained the preferred embodiment according to institute's accompanying drawings.
Refer to Fig. 1,2, be stereogram and the assembled sectional view of the first embodiment of autologous radiator structure of the present invention, as shown in the figure, autologous radiator structure 1 of the present invention, comprising: a pyrotoxin 11;
Wherein pyrotoxin 11 outer surface at least forms a heat loss through radiation layer 12 in side, and upper described pyrotoxin 11 is that a battery or semiconductor element or IC chip are wherein arbitrary, the present embodiment is using battery as explanation embodiment, but not regarding it as is limited also can be applicable to any pyrotoxin from knowing from experience generation heat certainly, and the outside material of described pyrotoxin is that ceramic material or metal material are wherein arbitrary.
Described heat loss through radiation layer 12 be a kind of loose structure or how rice structure or porous ceramic structure or porousness graphite-structure or high radiation ceramic structure or high-hardness ceramic structure wherein arbitrary, and described heat loss through radiation layer is by differential arc oxidation (Micro Arc Oxidation, or electricity slurry electrolytic oxidation (PlasmaElectrolytic Oxidation MAO), PEO), anodic spark deposition (Anodic Spark Deposition, ASD), spark deposition anodic oxidation (Anodic Oxidation by Spark Deposition, ANOF) wherein arbitrary side in this pyrotoxin forms cellular structure, certainly also by pasting and printing and be coated with wherein either type, heat loss through radiation layer 12 is formed on the outer surface of pyrotoxin 11.
Refer to Fig. 3, for the assembled sectional view of the second embodiment of the autologous heat loss through radiation structure of the present invention, as shown in the figure, the present embodiment is identical with aforementioned first embodiment portion of techniques feature, therefore will repeat no more at this, only the present embodiment is in described heat loss through radiation layer 12 for hitting produced concaveconvex structure by pearl from the different of aforementioned first embodiment.
