Aluminium edge copper type heating panel to heating module
Technical field
The utility model relates to heating panel, specifically is meant the aluminium edge copper type heating panel to heating module.
Background technology
Heating panel is a kind of device of giving the easy heat-generating electronic elements heat radiation in the electrical equipment, and how by aluminium alloy, brass or bronze are made tabular; Sheet; Splinteries etc. will use sizable heating panel like cpu central processing unit in the computer, power supply pipe in the television set; Administration-management, the power tube in the amplifirer all will use heating panel.General heating panel in use will be coated with the last layer heat-conducting silicone grease at electronic component and heating panel contact-making surface, and the heat that components and parts are sent is more effective to be transmitted on the heating panel, goes being dispersed in the surrounding air through heating panel.
With regard to the heating panel material, every kind of its heat conductivility of material is different, arranges from high to low by heat conductivility, is respectively silver, copper, aluminium, steel.Can be too expensive if but do heating panel with silver, so best scheme is copper for adopting.Though the aluminium considerably cheaper, obviously thermal conductivity is just not as copper good (approximately have only copper about 50%).
Heating panel material commonly used at present is copper and aluminium alloy, and the two respectively has its pluses and minuses.The thermal conductivity of copper is good, but price is more expensive, and difficulty of processing is higher, weight excessive (a lot of fine copper radiators have all surpassed the quantitative limitation of CPU counterweight), and thermal capacity is less, and oxidation easily.And fine aluminium is too soft, can not directly use, and the aluminium alloy that all is to use just can provide enough hardness, and the advantage of aluminium alloy is cheap, and is in light weight, but thermal conductivity will be far short of what is expected than copper.
For domestic consumer, be enough to reach radiating requirements with the aluminium heating panel.
The radiator of north of china in winter heating also is heating panel.
Heating panel occupies important role in the formation of radiator, except that the active heat removal of fan, evaluate the quality of a radiator, depends on the heat absorption capacity and the capacity of heat transmission of heating panel itself to a great extent.
Heating panel, in the existing heating panel, its material constitutes various ways, like fine aluminium or aluminium alloy, or fine copper or copper alloy.
Cost is no doubt cheap for fine aluminium or aluminium alloy, but its heat absorption and heat radiation function are not remarkable, and generally being applied to requires to dispel the heat needs little parts.For fine copper or copper alloy, its radiating effect is remarkable, but its production cost is very high, and is big for some heat radiation requirement, is worth but the cost input requires low parts extremely not adopt.Therefore, based on above-mentioned, we need a kind of low cost, and the heating panel of high efficiency heat radiation with the solution input that reduces cost, satisfies radiating requirements simultaneously.
The utility model content
The utility model purpose is to provide a kind of heating panel of low-cost high-efficiency heat radiation, in order to solve this purpose, and a kind of aluminium edge copper type heating panel to heating module is provided, and possesses high efficiency heat radiation and drops into cheaply.
The utility model implementation is following: to the aluminium edge copper type heating panel of heating module; Mainly constitute by heating panel and the absorber plate that is connected with heating panel; Said heating panel has the mosaic groove that is complementary with absorber plate, and said absorber plate is arranged in the mosaic groove.
In order to satisfy heating panel and absorber plate solderability, said heating panel outer surface is provided with the heating panel heat conducting film; The absorber plate outer surface is provided with the absorber plate heat conducting film.
The material of said heating panel heat conducting film and absorber plate heat conducting film is: anti-oxidant Heat Conduction Material.
Said heating panel heat conducting film and absorber plate heat conducting film are: plated nickel film or gold-plated film or copper plating film.
Between said heating panel heat conducting film and the absorber plate heat conducting film heat conduction junctional membrane is set.
Further, for making heating panel and absorber plate carry out seamless link, said heat conduction junctional membrane is the soldering tunic, and said heating panel heat conducting film is welded in the absorber plate heat conducting film through the soldering tunic.
Said absorber plate has the heat absorption groove away from mosaic groove bottom one side,
Said heating panel is an aluminium sheet, and said absorber plate is a copper coin.
The notch of said mosaic groove is provided with convexity, and the groove bottom of said mosaic groove offers some little grooves, and said absorber plate is provided with the detent that is complementary with the mosaic groove convexity.
The cross section of said heat absorption groove is the little butterfly face in big centre, two.Generally speaking, in order to increase radiating efficiency, the shape of heat absorption groove and the relative set heating module in the heat absorption groove is complementary.
In the utility model; Its production program is: remove earlier the aluminum or aluminum alloy plate, dig a mosaic groove that matches with copper coin at it, using nickel plating process; With aluminium sheet or aluminium alloy plate and copper coin plating nickel on surface, or electroplate the metal of other anti-oxidant heat-conductings.With the tin metal fusing, pour tin into mosaic groove again, simultaneously copper coin is fastened on the mosaic groove, compress, make tin overflow, make copper coin closely contact with the aluminum or aluminum alloy plate to appearance.When mounted at last, heating module is directly pasted clothes in the heat absorption groove, make heating module contact with the absorber plate heat conducting film of copper coin outer surface.
The utility model utilizes the good heat conductivity of copper, and heating module is absorbed heat, and utilizes the perfect heat-dissipating of aluminum or aluminum alloy, carries out the heat of copper coin conduction is dispelled the heat.
The utility model utilizes the plate body of unlike material, in conjunction with, utilize heat conduction and heat radiation performance separately different, to carry out the heating module radiating treatment, this design is heat-treated to the heat efficiency of difference position.Satisfying on the basis of radiating requirements, and reaching economical with materials, the purpose that reduces production costs.
The utility model compared with prior art has the following advantages and beneficial effect: cost is low, and is simple in structure, good heat dissipation effect.

Fig. 2 is the planing surface figure of the utility model.
Label among the figure is expressed as respectively: 1, heating panel; 2, absorber plate; 3, mosaic groove; 6, absorber plate heat conducting film; 4, heating panel heat conducting film; 5, heat absorption groove.
Embodiment
Like Fig. 1, shown in 2, to the aluminium of heating module edge copper type heating panel, mainly constitute by heating panel 1 and the absorber plate 2 that is connected with heating panel 1, heating panel 1 has the mosaic groove 3 that is complementary with absorber plate 2, and said absorber plate 2 is arranged in the mosaic groove 3.
Heating panel 1 outer surface is provided with heating panel heat conducting film 4; Absorber plate 2 outer surfaces are provided with absorber plate heat conducting film 6.
Heating panel heat conducting film 4 with absorber plate heat conducting film 6 is: plated nickel film
Between heating panel heat conducting film 4 and the absorber plate heat conducting film 6 the heat conduction junctional membrane is set.The heat conduction junctional membrane is the soldering tunic, and said heating panel heat conducting film 4 is welded in absorber plate heat conducting film 6 through the soldering tunic.
