Technical field
This utility model relates to dissipation from electronic devices sheet, particularly a kind of copper aluminum efficient radiator fin.
Background technology
Along with developing rapidly of modern science and technology, application popularization daily life, production or even the every field of electronic device,
Play extremely important role in modern civilization, at present, all kinds of electronic devices are always towards the trend development improving integrated level.
On the chip of high integration, the heat source density in all kinds of electronic devices and components is more and more higher.In all kinds of electronic devices and components at a relatively high
Heat source density, the operating temperature of electronic device directly affects its service life and stability, the work of each parts of PC to be allowed
Temperature is maintained in the range of reasonably, in addition to ensureing that the temperature of PC working environment is in the reasonable scope, it is necessary to be to it
Carry out the radiating treatment of more efficient energy.Thus find and have what the heat dissipating method always industry of efficient transportation usefulness was competitively pursued
Target.And along with the enhancing of PC computing capability, power consumption and heat dissipation problem are increasingly becoming the problem not allowing to avoid.Dissipating of electronic device
Heat problem becomes a technical problem anxious to be resolved.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, it is high that the purpose of this utility model is just to provide a kind of copper aluminum
Usefulness fin, can effectively solve the heat dissipation problem of electronic device.
The technical scheme that this utility model solves is, a kind of copper aluminum efficient radiator fin, including heat sink body, described
Heat sink body includes by aluminium sheet and inlays aluminium sheet upper surface copper coin, and the thickness of aluminium sheet is 13-15mm, the thickness of described copper coin
For 4-6mm, the upper surface of aluminium sheet and the upper surface flush of copper coin, the two is inlayed by the explosive welding composition that is closely linked
The tabular integrative-structure of formula.
Described aluminium sheet is square, and long and width is 180mm, and copper coin has identical three piece, is square, and long 120mm is wide
38mm。
This utility model novel structure is unique, and advantages of simple easily produces, low cost, and 3 copper sheets are well embedded in aluminium sheet
In, and combined by blast and make combining of stable performance that both are different, serve in terms of the heat radiation of electronic device
Well heat transfer and radiating effect, solves the heat dissipation problem in distribution three pieces of regions on circuit boards, and can be by adjusting copper sheet position
Put and apply in the electronic device of highly dense thermal source, easy to use, effective, there is good Social and economic benef@.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Fig. 2 is that the A-A of this utility model Fig. 1 is to sectional view.
Fig. 3 is the schematic diagram of this utility model explosive welding structure.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Being given by Fig. 1-3, this utility model includes that heat sink body, described heat sink body include by aluminium sheet 1 and edge
Embedding aluminium sheet upper surface copper coin 2, the thickness of aluminium sheet 1 is 13-15mm, and the thickness of described copper coin 2 is 4-6mm, the upper surface of aluminium sheet
With the upper surface flush of copper coin, the two is closely linked by explosive welding and constitutes inserted tabular integrative-structure.
For ensureing using effect, described aluminium sheet 1 is square, and long and width is 180mm, and copper coin 2 has identical three piece, all
For square, long 120mm, wide 38mm.
Described aluminium sheet 1 includes basic unit aluminium sheet 1a and coating aluminium sheet 1b, and heat sink body is by explosive welding structural blast
The integrative-structure constituted after welding, explosive welding structure, as cladding plate basic unit aluminium sheet 1a is provided with and copper by coating aluminium sheet 1b
The through hole 4 that plate is corresponding, copper coin 2 is filled in through hole 4, the upper and lower surface of copper coin respectively with the upper and lower surface of basic unit aluminium sheet 1a
Flushing, equipped with basic unit's aluminium sheet of copper coin as substrate, substrate, cladding plate are that parallel spaced-apart is arranged, the upper surface of substrate and cladding plate
Lower surface is the most right, and the two spacing is 7-9mm, and the upper surface of cladding plate is coated with explosive layer 3, and the thickness of explosive layer 3 is 28-32mm；
The outer of described cladding plate is beyond the outer of substrate；The outer of described cladding plate is beyond the outer 200mm of substrate.
In explosive welding structure of the present utility model, by increase medicated bag area, cladding plate relative to substrate, its length and width chi
Very little each increase 200mm, reduces the impact on compound plate borderline region of the explosion time reflected tensile stress, thus controls boundary effect, quick-fried
Fried welding cuts after completing.
Structure of the present utility model is that reasonable combination, improves together by copper aluminum homogenous material of the prior art
The shortcomings such as the heat radiation that single fin possesses is slow and heat transfer is slow, can quickly solve the heat effect problem of high integration electronic device,
Serve good heat dissipation problem.
This utility model have employed explosion welding method, is organically combined by two kinds of different metals, has good stability,
Good heat dissipation effect, quality is light and handy, and the prices of raw materials are moderate, design ingenious, easy to implement, can manufacture in high volume, and this practicality is new
Type is a technological improvement the most practical, safe and reliable, the most practical, easy to use, effective, has good society
Meeting and economic benefit.
