Considerably cheaper, it is apparent that thermal conductivity is just be not as good as copper（Only about 50% or so of copper）.
Currently used cooling fin material is copper and aluminium alloy, and the two respectively has its advantage and disadvantage.The thermal conductivity of copper is good, but price
More expensive, difficulty of processing is higher, and weight is excessive（Many fine copper radiators have been above limitations of the CPU to weight）, thermal capacity is smaller,
And it easily aoxidizes.And fine aluminium is too soft, it is impossible to directly use, all be that the aluminium alloy used could provide enough hardness, aluminium closes
The advantages of golden be it is cheap, it is light-weight, but thermal conductivity will be far short of what is expected than copper.Some radiators just respectively take the chief, are closed in aluminium
Embedded a piece of copper coin on golden foot of radiator.

The 63% of amount.
A kind of efficient LED cooling fin of the present invention has the advantages of practical performance is good, and flexibility ratio is big, and radiating efficiency is high.
Specific embodiment
The preferred embodiments of the present invention will be described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that so as to make a clearer definition of the protection scope of the present invention.
Wherein, the efficient LED cooling fin includes outermost OPS films, the hydrophilic coating film layer of middle layer and most
The matrix combination of internal layer forms, and the hydrophilic coating film layer includes the resin of resin binder and Porous particle, described matrix
Including graphite material, carbon material, tungsten alloy, the OPS films account for the 26%-30% of efficient LED cooling fin totality component, described
Hydrophilic coating film layer account for the 10%-11% of efficient LED cooling fin totality component, the matrix accounts for efficient LED cooling fin totality
The 58%-66% of component.
It further illustrates, the OPS films are oriented polystyrene heat-shrinkable film, and the OPS films account for efficiently
The 26% of LED cooling fin totality components, the hydrophilic coating film layer accounts for the 11% of efficient LED cooling fin totality component, described
Matrix accounts for the 63% of efficient LED cooling fin totality component.
It is further illustrating, the characteristics of OPS films, the transparency：It is plasticized by heating, puies forward the rigidity of polymer segment
Height increases intermolecular force, then shows the characteristic that pledge is hard, transparent at room temperature.It is very main in the optical property of OPS
As soon as what is wanted is that it can penetrate the visible ray of all wavelengths, this makes OPS films have the glossiness of height, this 2 points just
It is to the basic demand of material in forming label, without certain rigidity, trade mark without certain deflection, cannot just adapt to not
The requirement of the trademark plastering machine of disconnected speed-raising.Equally, the high transparency of film, be easy to coloring the characteristics of again for fineness trade mark making establish
Basis, can be designed that the label of various different shape and pattern.High shrinkage：OPS compensates for traditional blowing-up technology
The defects of shrink film, its lateral shrinkage may be up to 80%, and the index request of this high shrinkage can make trade mark in difference
It realizes fit on the container of shape, shows out the body of container especially, make packing material more vivid, can also obtain and anti-riot split and seal
The effect of health.Shrinkage：When variations of the OPS in heat contraction process, the heating during trade mark use is complied fully with
Form will not affect greatly container and filling beverage, it is seen that the energy consumption in the use of label does not also increase
Add, can be declined slightly instead.Equally, relatively low natural shrinking rate, what this point made heat shrink films has promoted the use of a matter
Leap.Since under room temperature of the OPS heat shrink films below 60 DEG C, almost without contraction, this makes during heat shrink films use
The too short a succession of puzzlement of the transport of appearance, storage, packaging, the film term of validity and problem are resolved, and are carried for forming label quotient
It has supplied technical guarantee and has created condition to reduce cost.The feature of environmental protection：The environmentally friendly adaptability of OPS heat-shrinkable films is this new
One power source of developing material and the important reason that PVC is substituted as label material.With the hair of world economy
Exhibition, one continue, the theory of environmental protection and requirement are in recent years in continuous in-depth and universal, it is so-called continue be exactly in order to effectively,
It is low-keyed to utilize resource, such a requirement for recycling or becoming the energy is proposed in the exploitation of new product.OPS
It is compared with PVC with such a projecting point, it can not only be turned with recycling even if printing later trade mark and can burn
Become the energy, due to the non-toxic and tasteless of it so not generating any pernicious gas, any pollution will not be generated.Opposite PVC
It can not just burn when containing chlorine（The chlorine generated after burning can destroy ozone layer）Even if recycling, because the cost of recycling is also larger,
And the gold content reused is too low, and lose more than gain.Economic and practical：OPS heat shrink films are in addition to the elder generation in technical indicator
Into other than property, the economical and practical of it be can not ignore：(its density only has 1.05 grams/cube li to the low-density of OPS materials
Rice;PVC1.35 grams/cc, PET1.38 grams/cc)；It processes early period and the plasticizing again in film-forming process, OPS
Fisheye（It is commonly called as flake）Almost without so as to make the problem of bringing yield rate reduction due to fisheye to printing, fundamentally
It is changed；Since its planarization is good, can thoroughly change previous PVC heat shrink films can only narrow printing the problem of, can be with
Meet the requirement of wide cut high speed printing, so as to bring the effect for reducing cost when improving efficiency to producer.The present invention provides
A kind of efficient LED cooling fin has the advantages of practical performance is good, and flexibility ratio is big, and radiating efficiency is high.
