Description
Technical field
The utility model belongs to heat abstractor technical field more particularly to a kind of subway lamp box graphene radiator.
Background technology
At present, both at home and abroad in current subway lamp box using LED lamp with on-line equipment on backboard by the way of, for it
Heat dissipation problem does not do specially treated.It is the effects that lamp box provides illumination, decoration, not only practical but also beautiful in subway.But light bar is made
For one of main member in lamp box, since electric energy 100% cannot be converted to luminous energy, remaining is discharged in the form of thermal energy.And it grows
The thermal accumlation of phase can cause lamp life to reduce, and high-temperature oxydation easily occurs for the portion of material in lamp box, and multiple heat expansion is cold
Contracting causes to deform.Material quality is caused to decline.Temperature is higher, and electric impedance is higher, and the heat of generation is more, such to cross thermal cycle
Easily cause electronic device failure.What is particularly drawn attention is that a large amount of heat radiation is larger to the injury of people, can cause skin for a long time
Skin is dry and astringent, blurred vision, seriously affects the body and mind of passenger.And the country does not have preferably the heat dissipation problem at the light bar back side also at present
Solution, the lamp box heat dissipation problem in subway is also in conceptual phase to be solved.
In conclusion problem of the existing technology is：Long-term thermal accumlation can cause lamp life to reduce, and lamp box
In portion of material high-temperature oxydation easily occurs, repeatedly expanding with heat and contract with cold causes to deform.Material quality is caused to decline.Temperature is higher,
The impedance of electricity is higher, and the heat of generation is more, and such thermal cycle excessively easily causes electronic device failure.What is particularly drawn attention is
A large amount of heat radiation is larger to the injury of people, can cause that skin is dry and astringent, blurred vision for a long time, seriously affects the body and mind of passenger.
Invention content
In view of the problems of the existing technology, the utility model provides a kind of subway lamp box graphene radiator.
The utility model is realized in this way a kind of subway lamp box graphene radiator, the heat dissipation of subway lamp box graphene
Device is provided with Lamp case frame, is bolted inside the Lamp case frame and is equipped with backboard, the upper end coating of the backboard
There are graphite ene coatings.
Further, LED lamp band is installed on the backboard, the front end of the Lamp case frame is pasted with and light bar phase
The picture matched.
Further, the Lamp case frame uses aluminium alloy frame.
The advantages of the utility model and good effect are：
1st, graphene technology is introduced in existing subway lamp box structure, the application of graphite ene coatings can be effectively improved in lamp box
Environment, reduce thermal energy that it stores for a long time.Ensure that environment temperature is unlikely excessively high or overheats in lamp box；
2nd, for graphite ene coatings by fabulous heat conductivility, the introducing of graphene can greatly improve the heat resistance of back board structure
Can, make the operating temperature of entire lamp box hot zone effectively reduce by 25%；
3rd, the graphite ene coatings are in the light bar back side, can in time absorption modulation band reflection heat, effectively solve light bar overheat,
The problem of back side is difficult to radiate；
4th, the introducing of graphite ene coatings, does not influence lamp box original structure, does not influence the beauty and original function of lamp box, peace
The thermal environment of lamp box is effectively improved entirely, and then lamp life reduces, material quality declines caused by solving light bar overheat
And the problem of electronic device failure, the seating environment of subway is effectively improved, has ensured the physical and mental health of passenger.
Description of the drawings
Fig. 1 is the structure diagram for the subway lamp box graphene radiator that the utility model embodiment provides；
In figure：1st, Lamp case frame；2nd, backboard；3rd, LED lamp band；4th, graphite ene coatings；5th, picture.
Specific embodiment
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Detailed description are as follows for attached drawing.
The structure of 1 pair of the utility model is explained in detail below in conjunction with the accompanying drawings.
The subway lamp box graphene radiator, subway lamp box graphene radiator are provided with Lamp case frame 1, the lamp
It is bolted inside cabinet frame 1 and backboard 2 is installed, the upper end of the backboard 2 is coated with graphite ene coatings 4.
As the preferred embodiment of the utility model, LED lamp band 3, the Lamp case frame are installed on the backboard 2
1 front end is pasted with the picture 5 to match with light bar 3.
As the preferred embodiment of the utility model, the Lamp case frame 1 uses aluminium alloy frame.
The operation principle of the utility model：Uniform graphene coated coating 4, realizes and lamp box is dissipated on the backboard 2 of lamp box
The solution of heat problem.1 general selection of Lamp case frame is aluminum alloy materials, plays integrated support in lamp box；Backboard 2 is placed in
In Lamp case frame 1, link together by bolted connection with Lamp case frame 1.Led light bar 3 is according to subway lightbank sizes
Its quantity is rationally designed, and according to certain arrangement device on backboard 2, the main effect that illumination is provided.LED lamp band 3
As one of main member in lamp box, since electric energy part is discharged in the form of thermal energy.And long-term thermal accumlation can cause
Lamp life reduces, and material quality declines.Temperature is higher, and electric impedance is higher, and the heat of generation is more, such to cross thermal cycle pole
Easily cause electronic device failure.Especially a large amount of heat radiation is larger to the injury of people.
Graphite ene coatings 4 are coated uniformly on backboard 2.Mainly solve the problems, such as light bar 3 overheat, backside radiator.Graphene applies
Layer 4 has high thermal conductivity factor, and up to 5300W/mk can be greatly reduced local temperature, and performance is better than carbon nanotube.Uniformly
Coated in the graphene on backboard 2, the operating temperature of lamp box hot zone can be made effectively reduce by 25%.Picture 5 is pasted by gluing
On frame.
The structure is not on the basis of original lamp box structure is changed, the uniform graphene coated coating 4 on lamp box backboard 2,
Graphite ene coatings 4 have high thermal conductivity factor, can effectively solve lamp box heat dissipation problem, so as to avoid because lamp box overheat causes
Device aging, the problems such as passenger experience sense is poor occurs.And do not influence the beauty and original function of lamp box.Can be that the country is used to solve
Certainly lamp box heat dissipation problem provides a kind of effectively with reference to technology.
