Heat is taken away.The tail end of heat pipe 210 is placed in radiating fin 220, and radiating fin is sandwich construction, can be effectively increased scattered
Hot area, fan 230 and 220 adjacent installation of radiating fin, fan 230 rotation by air inlet 310 suck cold wind, suction it is cold
Wind cools down condensing reflux to the water droplet that on the heat pipe 210 being placed in 220 structure of radiating fin, can make in heat pipe 210, with this
Move in circles and do not stop the heat of LED region being ultimately converted to hot wind to be blown projection light machine system by air outlet 320, this is cold
The region that wind-heat wind is passed by is air passage.
It is considered that after the equipment operation of said structure, by the work continued for some time, since passenger inside the vehicle circulates,
Equipment is in the state for being very easy to accumulation batting, and these positions are included between radiating fin and fan, radiating fin and knot
Between structure wall, inside radiating fin.And these batting sizes are larger, it is difficult to be cleared up from outside, it also is difficult to using easy dust catcher
It is suctioned out at air outlet, so, there is the problem of cleaning trouble.
To solve the above-mentioned problems, in the present embodiment, also on the outside of projector's machine, one is pasted at wind inlet of fan
The size Air Filter 311 more bigger than air inlet overall dimensions.The Air Filter is preferably nylon net cloth material, when batting class dust connects
When contacting nylon material, nylon wire can produce electrostatic, at this moment will firmly adsorb batting class dust.Nylon Air Filter
Surrounding has a circle gum conveniently to stick on the outside of machine, when Air Filter has adsorbed more batting, then can easily remove and replace with
New Air Filter.
The emphasis of Air Filter design is the selection of its density namely mesh number, because if too close, then influences air intake efficiency,
So the radiating efficiency of projection light machine will have a greatly reduced quality；And if too thin, dust-proof effect declines, the batting of some small sizes
Booty can not then effectively filter out.
If table 1 below is Air Filter mesh number and filtering accuracy table：
| Mesh number | Filtering accuracy μm | Mesh number | Filtering accuracy μm |
| 5 | 3900 | 140 | 104 |
| 10 | 2000 | 170 | 89 |

| 120 | 124 | 1300 | 11 |
Note：The mesh number of filter screen refers to the grid number on area per square inch
Experiment proved when selecting the filter screen of 500 mesh, and influence to heat dissipation is in tolerance interval, and specific correction data is such as
Table 2 below：
In 20~25 degree Celsius ranges it can be seen from data comparison, two kinds of Air Filter temperature rises are on 2 degrees Celsius of left sides
The right side, in 30~40 degree Celsius ranges, 500 mesh Air Filter temperature rise about in 3 degrees centigrades, and 600 mesh Air Filter temperature are climbed
Rise about in 6 degrees centigrades, and at 45~55 degrees Celsius, since environment temperature is higher, integral heat sink efficiency declines, 500 mesh
Difference is risen within 2 degrees Celsius with the temperature of 600 mesh.
In view of projection light machine normal working temperature scope in 20~40 degrees centigrades, then this two sections data has more
Reference value.Based on this, the temperature rise that the Air Filters of 500 mesh is brought is substantially within 3 degrees Celsius, and 600 mesh performances are than this
Difference.
Generally there is certain redundancy in view of heat dissipation design, the heat that temperature rise is brought within this 3 degrees Celsius is not increasing
Still can effectively it be dispersed in the case of cost, and such as temperature rise higher, then system radiating design needs rethink increasing surplus, such as increase
Add the measures such as rotation speed of the fan and air quantity, thus necessarily bring increase and other integrity problems of cost.
The Air Filter of 500 mesh is have finally chosen, and the Air Filter of 500 mesh is as can be seen from Table 1, can filter out diameter>
The dust and batting of 25um, this can greatly reduce into the foreign matter inside projector, so as to reduce system maintenance cleaning
Cost price.
To sum up, projector dustproof net is Air Filter of the stickup with suitable mesh number outside air inlet, Air Filter mesh number
Selection needs, according to real system heat-sinking capability, to select larger Air Filter mesh number as far as possible, and simultaneously because being pasted on outside structure
Side, can conveniently remove replacement.
In the present embodiment, will also be carried out between fan 230 and radiating fin 220 it is non-be close to design, this gap has two
A reason causes：First, because structure tolerance leads to not be close to；If second, fan can closely be brought very much apart from radiating fin compared with
Big high frequency noise, the similar effect blown a whistle, and if pulling open a determining deviation, then the effect of boatswain's pipe will reduce.But
This gap can be brought the problem of new：Because there is gap between fan and fin, and this gap is located at air passage center, then this
Accumulation batting is just very easy at a gap, the batting of this netting caking can seriously affect complete machine radiating efficiency；In order to solve
The dirt exclusion capabilities of this equipment are further improved, the present embodiment also pastes a foam in the top of radiating fin 220 and fan 230
240, such as perforate PE foams, on the one hand which can further eliminate boatswain's pipe, another side can also effectively filter out batting heap
Product.
