After the base material layer formed by the cooling material is adopted, the heat can be dissipated in a way of radiation; the heat can be released by the cooling material; and the base material layer is compounded with the polythene material, so that the strength of the aluminum sheet is improved, and the material has good insulating property due to the polythene material.
Description
Technical field
The utility model relates to a kind of aluminium flake, specially refers to the compound aluminium flake of a kind of heat radiating type.
Background technology
Along with science and technology progresses greatly day by day, following electronic product and Equipment Design will have following trend: compact, portable, do not take up space; High processing rate, high efficiency; Unit is multi-functional, but thing followed problem: and the too small heat radiation in space is difficult for, and processing speed is accelerated, and temperature raises.
Aluminium is the highest metal of content on the earth, and low the hanging down with thermal capacitance of cost is its main feature, with respect to noble metal copper; Though heat absorption is slow, heat release is fast, and radiating effect is directly proportional with its structure and workmanship simultaneously; Fin count is more, the bottom polishing is good more, and radiating effect is good more.Its radiating principle utilizes the fin on the radiator to increase the contact area with air, flows and takes away the heat on the fin thereby utilize fan to quicken air again.Adopt the fin of fine aluminium material cheap, its good processing characteristics is more outstanding on radiating effect simultaneously.
Traditional on the market generally speaking slim aluminium flake, general thickness about 0.05 ~ 0.5mm, the strength of materials a little less than, processing back forms warpage, bending easily.And utilize the big steel plate of the strength of materials, and it is applied the thermal diffusivity material, but the effect of heat radiation is unsatisfactory.High heat absorption japanning product is a kind of product that possesses heat radiation and electric conductivity on the market, generally adopting conventional manufacturing technique for painting dressing at the clad steel sheet upper surface and the back side, is coated with pretreatment layer; The back side second layer has applied the heat radiation coating; The upper surface second layer is a priming paint, and the 3rd layer is finish paint, but its preparation technology is comparatively complicated; Cost is higher relatively, and its thermal diffusivity has much room for improvement.
One Chinese patent application numbers 200620042239.6, a kind of heat radiation conduction color coated steel sheet comprises substrate and composite coating; Composite coating is for to be coated with anti-fingerprint coating at the back side of substrate, and the surface is coated with anti-fingerprint coating, priming paint and finish paint successively above that, and anti-fingerprint coating is an acrylate resin layer; Although its intensity is higher, its structure is comparatively complicated, and manufacturing cost is higher; Radiating effect remains to be improved, and its quality is bigger simultaneously, is unfavorable for the application in the heat radiation manufacturing field of electronic product industry.
The heat radiation aluminium flake is for the development of miniature electronic product in the prior art; The particularly raising at full speed of miniature electronic product technology in recent years, increasing demand is strong, and especially the treatment effeciency of miniature electronic product is increasingly high; Cause electronic product and equipment self temperature to raise; If can't overcome the relatively poor problem of intensity of quick discharge heat and aluminium flake, will cause shorten service life, bring puzzlement to the user.
Summary of the invention
1. invent the technical problem that will solve
To slim aluminium flake traditional in the prior art; General thickness is at 0.05 ~ 0.5mm, the strength of materials a little less than, the processing back forms warpage, bending easily; The utility model provides a kind of heat radiating type compound aluminium flake; Through compound one deck PEF (PET) material, increase the intensity of aluminium flake, PEF (PET) material also possesses the good insulation performance performance simultaneously.
2. technical scheme
The compound aluminium flake of a kind of heat radiating type comprises substrate layer, also comprises the PEF layer, and the front of said substrate layer or the back side are coated with the PEF layer.
Said substrate layer is made up of aluminium flake and heat sink material, scribbles heat sink material on the front of aluminium flake.
Said PEF layer thickness 0.05mm.
The thickness of said aluminium flake is 0.05 ~ 0.5mm.
3. beneficial effect
(1) scribbles the substrate layer of forming by heat sink material,, heat is dispelled the heat through radiation mode.
(2) see through heat sink material self and realize that heat discharges.
(3) in the compound one deck polyethylene material of substrate layer, strengthened the intensity of aluminium flake, polyethylene material makes material possess the good insulation performance performance simultaneously.
