Specific implementation mode
Further to illustrate the technological means and its effect of the invention taken, below in conjunction with the preferred implementation of the present invention
Example and its attached drawing are described in detail.
The specific embodiment of the invention provides a kind of display screen.
Please refer to Fig.1-3, the display screen includes bottom case 10, the lamp plate 20 that is set on bottom case 10, is contained in bottom case 10
In several deflectors 30, two sealing rings 40, two babinets 50 and the fan 60 being disposed therein on any babinet 50.
The bottom case 10 uses hermetic design.The side of the bottom case 10 is formed with for accommodating the lamp plate 20 and the deflector
The both ends of 30 holding tank 11, the opposite other side are respectively formed with two ventilation openings 12 and two side-inlets 13.Air-flow can pass through
The side-inlet 13 enters in bottom case 10, then is flowed out outside the bottom case 10 by the ventilation opening 12, to reduce display in bottom case 10
The temperature of unit.Further, the periphery of the ventilation opening 12 at 10 both ends of bottom case is provided with the sealing ring 40, so that the display screen
With waterproof effect.
Two babinet 50 is located at the both ends of the bottom case 10.The fan 60 is set on any babinet 50, and the setting
There is the position that the babinet 50 of fan 60 corresponds to the ventilation opening 12 to be formed with opening (not shown) so that air-flow can by the opening and
The ventilation opening 12 is discharged, and after opening the fan 60, which can extract the air-flow in the bottom case 10 out, to reduce in bottom case 10
Temperature.The fan 60 can be used as the source that the air-flow in the display screen exchanges power.
Two first steps 14, two second steps 15 and two third steps 16 are formed in the holding tank 11.The First
The 16 radial parallel setting of rank 14, the second step 15 and the third step.The height of the first step 14 be more than this second
The height of the height of step 15 and the third step 16.
Two first step 14 is formed radially in the two of the holding tank 11 inner surface being oppositely arranged.The First
Rank 14 is used to support the lamp plate 20.The lamp plate 20 is main heat source.
Two second step 15 fits in the inner surface setting of the first step 14 respectively.
The two thirds step 16 is respectively positioned between two second step 15, and the second step 15 and the third
Step 16 is spaced setting so that is collectively formed outside two groups between second step 15, third step 16, deflector 30 and bottom case 10
Inner cavity (not shown) is collectively formed in chamber 70 between lamp plate 20, first step 14, bottom case 10 and deflector 30.Intelligible, this is outer
Chamber 70 can be penetrated through directly with the air outside bottom case 10.The inner cavity and the air flow direction in the 70 bootable bottom case 10 of exocoel.
Each second step 15 and the centre position of each third step 16 are recessed along the direction towards 11 bottom wall of holding tank
It is respectively formed with the first depressed area 151 and the second depressed area 161 so that the inner cavity and the air-flow of the exocoel 70 pass through the first recess
Area 151 is mutually communicated with the second depressed area 161, to form a mixed zone 90.That is, exocoel 70 and the air-flow of inner cavity can
It is exchanged in the mixed zone 90, to reduce the temperature difference in bottom case 10, achievees the effect that reduce components interior temperature.
The deflector 30 is located at the both ends of second step 15 and third step 16 that every two are disposed adjacent.This implementation
In example, the quantity of the deflector 30 can be four.Each deflector 30 is each formed with several ventholes 31.And each deflector
30 do not cover first depressed area 151 and the second depressed area 161.
Exocoel 70 can also be swapped with the air-flow in inner cavity by several ventholes 31, to reduce in bottom case 10
Temperature difference achievees the effect that reduce components interior temperature.Because lamp plate 20 is main heat source, the heat that lamp plate generates can be transferred to
Inner cavity air-flow, inner cavity air-flow can slowly be exchanged by venthole 31 with the air-flow in exocoel 70, and small air-flow agitation is formed,
To the significantly more efficient heat for reducing lamp plate 20.
Fan 60 is opened, fan 60 is extracted to 50 outer exhausting of babinet, air-flow from two ventilation openings 12 close to the fan 60
Outside bottom case 10, specifically, the air-flow in bottom case 10, under the action of fan 60, fraction passes through two groups of exocoels 70
It is flowed along close to the direction of the fan 60, another part air-flow can be flowed by inner cavity along close to the direction of the fan 60, flowed
During dynamic, inner cavity and the air-flow of exocoel 70 can be swapped by venthole 31, with the temperature difference of balanced bottom case 10, interior exocoel
Air-flow further flow to mixed zone 90, in the mixed zone 90, inner cavity can also be swapped with the air-flow in exocoel 70, air-flow
Inner cavity 70 after exchange is further flowed with the air-flow in exocoel 80 and passes through the mixed zone after 90s, and the air-flow of interior exocoel is further
By the progress air-flow exchange of venthole 31, the temperature of electronic component in further equilibrium bottom case 10, when the air-flow of interior exocoel passes through
It is flowed out outside bottom case 10 by the ventilation opening 12 after deflector 30, to reduce the temperature of electronic component in bottom case 10.In above-mentioned stream
During dynamic, the heat that lamp plate 20 is sent out can be transferred to the air-flow of inner cavity, and the air-flow of interior intracavitary passes through mixed zone 90 and venthole
31 swap with the air-flow in exocoel 70, to reduce the heat of lamp plate 20, the temperature difference of electronic component in balanced bottom case 10.
It should be understood that fan 60 and being formed with the babinet 50 of opening and may be disposed at the either end of bottom case 10, so that air-flow
It can be discharged from the either end of bottom case 10.
The above for those of ordinary skill in the art can according to the technique and scheme of the present invention and technology
Other various corresponding change and deformations are made in design, and all these change and distortions should all belong to the claims in the present invention
Protection domain.
