Abstract
The invention discloses a metal support with a surface sprayed with a nano-carbon heat dissipation material. The metal support comprises a rear shell metal support (101). An inner surface of the rear shell metal support (101) is sprayed with a nanometer carbon layer (102). A processing method of the metal support with the surface sprayed with the nano-carbon heat dissipation material comprises the following steps that S1, the inner surface of the rear shell metal support (101) is polished through a laser carving technology so that surface pretreatment of the rear shell metal support (101) is realized; S2, an electrostatic adsorption mode is used and liquid nanometer carbon paste is sprayed on the polished surface in the step S1; S3, drying processing of the liquid nanometer carbon paste is performed, the rear shell metal support (101) which is sprayed with the nanometer carbon is sent to a baking oven so as to carry out baking, and the baking oven carries out moisture drying on the liquid nanometer carbon paste; S4, cooling of the rear shell metal support (101) is performed and the rear shell metal support (101) in the baking oven is taken out. The metal support and the technology have the following advantages that thickness of a whole machine is reduced; an appearance is beautiful and a heat dissipation effect is good.
Description
Technical field
The present invention relates to, particularly a kind of metallic support of surface spraying nano-sized carbon heat sink material and treatment process thereof.
Background technology
At present, moving camera gradually towards lightweight, volume is little, future development, and needs video recording such as high definition such as shooting 2K, 4K etc.Because existing moving camera inside chip concentrates multi-core CPU and GPU, multi-core CPU and GPU power consumption are very large, generate heat very large in shooting process; In addition, camera part is operationally generated heat more concentrated, causes whole moving camera temperature to raise.Usually graphite radiating film is adopted to be attached in the structures such as metallic support at present, to realize the heat dissipation problem of moving camera inside, but, the bonding double faced adhesive tape adding conductive coefficient extreme difference is needed between graphite radiating film and metal frame, the heat of metallic support is caused cannot to be promptly transmitted on graphite radiating film, heat is caused to pile up at interiors of products, influential system performance.In addition, the trend of current electronic product is ultra-thin, and inner space is all more nervous, adopts and pastes graphite radiating film to change a difficult problem for loose radiating condition, not only increase complete machine thickness, and cause adverse effect to structural design.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, a kind of thickness, good looking appearance, the metallic support of surface spraying nano-sized carbon heat sink material of good heat dissipation effect and the treatment process thereof that reduce complete machine are provided.
Object of the present invention is achieved through the following technical solutions: a kind of metallic support of surface spraying nano-sized carbon heat sink material, and it comprises back cover metallic support, and the inner surface of described back cover metallic support is coated with nano-carbon layer.
A treatment process for the metallic support of surface spraying nano-sized carbon heat sink material, it comprises the following steps:
The preliminary treatment of S1, back cover metallic support, by the inner surface of back cover metallic support by the polishing of radium technology for fast carving on, thus achieves the surface preparation of back cover metallic support;
The mode of S2, employing Electrostatic Absorption, sprays on the surface after polishing in step sl by liquid nano carbon slurry;
The drying and processing of S3, liquid nano carbon slurry, sends the back cover metallic support being coated with nano-sized carbon into baking box and toasts, and the moisture in liquid nano carbon slurry is dried by baking box;
The cooling of S4, back cover metallic support, takes out the back cover metallic support in baking box, back cover metallic support is carried out air cooling.
The present invention has the following advantages: the present invention is sprayed on nano-carbon material high for coefficient of heat transfer on metallic support, can the radiating efficiency of significant increase heat radiating metal rack surface, reduces the temperature in equipment work; Meanwhile, owing to instead of heat dissipation film by double faced adhesive tape to the conventional method on metallic support, reduce equipment inner structure thickness again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1-back cover metallic support, 2-nano-carbon layer.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As shown in Figure 1, a kind of metallic support of surface spraying nano-sized carbon heat sink material, it comprises back cover metallic support 101, the inner surface of described back cover metallic support 101 is coated with nano-carbon layer 102, as the dotted line frame in Fig. 1 the region that surrounds be nano-carbon layer 102, nano-carbon layer 102 has high thermal conductivity coefficient.
A treatment process for the metallic support of surface spraying nano-sized carbon heat sink material, it comprises the following steps:
The preliminary treatment of S1, back cover metallic support 101, by the inner surface of back cover metallic support 101 by the polishing of radium technology for fast carving on, thus achieves the surface preparation of back cover metallic support 101;
The mode of S2, employing Electrostatic Absorption, sprays on the surface after polishing in step sl by liquid nano carbon slurry;
The drying and processing of S3, liquid nano carbon slurry, sends the back cover metallic support 101 being coated with nano-sized carbon into baking box and toasts, and the moisture in liquid nano carbon slurry is dried by baking box;
The cooling of S4, back cover metallic support 101, takes out the back cover metallic support 101 in baking box, back cover metallic support 101 is carried out air cooling, thus the metallic support of final obtained surface spraying nano-sized carbon heat sink material.The heat conduction that the processor of moving camera inside, first-class pyrotoxin of making a video recording send is on the inner surface of back cover metallic support 101, because back cover metallic support 101 coats the nano-carbon material of high thermal conductivity coefficient on the surface, heat can be diffused into camera surface rapidly, thus reduce camera internal temperature, ensure camera camera system works fine.
The above is only the preferred embodiment of the present invention, be to be understood that the present invention is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from the spirit and scope of the present invention, then all should in the protection range of claims of the present invention.
