Different product stepping classification, can true operation condition be 60 DEG C or -20 DEG C, at this moment LED, IC working efficiency and performance not
Unanimously, as soon as what may be belonged to originally grade will become multi gear, and brightness is inconsistent, screen body also becomes naturally to be spent.This is because
Under different temperature conditions, the brightness decay and decline of three kinds of lamps of red, green, blue are different, and at 25 DEG C, white balance is
Normally, but at 60 DEG C, the brightness of the LED of three kinds of colors is all declined, and its pad value is inconsistent, so will produce
The quality of the phenomenon that whole screen brightness decline and colour cast, whole screen will decline.And ICThe operating temperature range of IC be -40 DEG C -
85℃.Case body temperature is caused to increase since ambient temperature is excessively high, if the temperature inside the box is more than 85 DEG C, IC if can be because of temperature
It is excessively high and lead to that job insecurity or temperature drift are different and to generate difference between interchannel electric current or piece excessive and cause to spend screen.
Meanwhile power supply is also particularly significant, and since power supply is under different temperature conditions, job stability, output voltage
Value and carrying load ability would also vary from, since it is responsible for logistics support effect, so its supportability directly affects
To the quality of screen.
Therefore, whether the hot loop system design of ventilation and heat is good, the extension with the available machine time and ambient temperature
It increases, the thermal drift of component can also increase, and so as to cause poor quality images, influence quality and the service life of display screen, institute
It is very necessary with designing a kind of hot loop device of ventilation and heat being adapted to environment influence.

Specific implementation mode
Below in conjunction with drawings and examples, the present invention is further described：
As shown in Figure 1, heat radiator device after a kind of LED screen of the present invention, including ontology 1 and rotation axis 2 form, it is described
The both sides of ontology 1 are equipped with circular blister 3 and circular pit 4, and the ontology 1 is made of metal sheet punching press, side it is described
Circular blister 3 forms the circular pit 4 in the other side of the ontology 1, and the circular pit 4 of side is in the ontology 1
The other side form the circular blister 3, the center of the center of the circular blister 3 and the circular pit 4 is equal
Offer the through-hole 5 through the ontology 1, the circular blister 3 and the circular pit 4 of homonymy according to a row circular blister 3,
One row circular pit, 4 alternately arranged mode is arranged, and this structure makes air at the both sides for flowing through the absorber plate, can disturb
The flow direction of random air makes air climb between circular blister 3 and circular pit 4, shunts and flow through depressed area, greatly prolongs
Air flows through the time of ontology 1, and through-hole set on 4 center of circular blister 3 and circular pit can make absorber plate both sides
Air circulation, further improve the upset effect of air.
As shown in Fig. 2, the side inside the ontology 1 is equipped with heat absorbing sheet 11, the other side is equipped with cooling fin 12, heat absorbing sheet 11
The both sides outer wall that Heat Conduction Material 13, heat absorbing sheet 11 and cooling fin 12 are provided between cooling fin 12 along ontology 1 is uniformly distributed, and is inhaled
Backing 11 and cooling fin 12 further improve the effect of heat dissipation, as shown in figure 3, described in transversely arranged adjacent two row of homonymy
In circular blister 3 and the circular pit 4, the circular pit 4 corresponds to the midpoint of two circular blisters 3 adjacent thereto
Position is arranged, in the homonymy vertically disposed adjacent two row circular blister 3 and the circular pit 4, the circular pit 4
The point midway setting of corresponding two circular blisters 3 adjacent thereto, the diameter of the circular blister 3 are equal to the circle
The diameter of pit 4 is arranged, and setting in this way can make the temperature equalization between each unit case, since case body temperature also can be by air
Convection current influence and temperature is inconsistent, cause the temperature between unit box or inside unit box different, bring semiconductor device
Part working efficiency is inconsistent, to which the light emission luminance for showing as LED light is inconsistent, it appears that " flower " shields, circular blister and circle
Pit, which is symmetrically arranged, can make the uniform temperature equalization of LED box inner air convection current, also, circular blister 3 and circle
The distribution of pit 4 is more carefully and neatly done, manufacture easy to process.
Specific implementation is described as follows：
Summer ambient temperature is excessively high, and temperature may be at 60 DEG C or more after LED screen, and internal temperature is more than external temperature, rotation
Heat radiator device makes male and fomale(M＆F) of the side equipped with heat absorbing sheet towards LED light point position, internal heat flows body circulation, from circle drum
Bubble and the through-hole of circular pit circulate, and hot fluid climbs between circular blister and circular pit, shunts and flow through depressed area,
Time of the hot fluid through radiator is substantially prolonged, keeps the heat transfer area of heat absorbing sheet and hot fluid larger, heat transfer efficiency is higher,
For heat absorbing sheet by Heat Conduction Material and cooling fin heat exchange, side sets gelled male and fomale(M＆F) towards the external world, forms radiating fin,
With larger surface area, temperature gradient can be quickly flattened, and heat is further up scattered away, to play good dissipate
Thermal effect；It, may be at -20 DEG C hereinafter, internal temperature is not necessarily to, to external cooling, rotate heat radiator when winter ambient temperature is too low
Device makes side set gelled male and fomale(M＆F) towards LED light point position, makes three kinds of lamp luminescences of LED display red, green, blue,
It shines can generate heat surely, and internal temperature is maintained at 25 ° or so as possible.
Wherein：Heat radiator device in the present invention is using a row Tapered Bubble Column, an alternately arranged side of row pyramidal pits
Formula setting can also have same heat radiator effect, heat radiator device that can judge whether to pass through rotation axis by the way that temperature detector is arranged
Transformation selects different sides, specific implementation mode to can be found in above-described embodiment, and this will not be detailed here.
The foregoing is merely the better embodiments of the present invention, and the invention is not limited in the above embodiments, are implementing
There may be the small structural modifications in part in the process, if the various changes or modifications of the present invention are not departed from the essence of the present invention
God and range, and belong within the scope of the claim and equivalent technologies of the present invention, then the present invention is also intended to comprising these changes
And modification.
