Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in embodiment of the present utility model is entered
Row clearly and completely describes, it is clear that and described embodiment is only the utility model part of the embodiment, rather than all
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, belong to the scope of the utility model protection.
As shown in Figure 1 and Figure 2, a kind of projector radiating device of the present utility model, its structure are as follows：Dividing plate 11 will project
Instrument is divided into operating room 12 and mixing chamber 13, and a radiator 2 is provided with the light source of operating room 12, positioned at mixed on dividing plate 11
The side of air chamber 13 has mounted a fins group 3, is connected between radiator 2 and fins group 3 by heat conducting pipe 21, at such light source
Caused heat is absorbed by radiator 2, and being delivered to fins group 3 via heat conducting pipe 21 is radiated.
The side for being located at operating room 12 in dividing plate 11 is provided with a fan supporter 4, and the first wind is installed on fan supporter 4
Machine 5, a hole is provided with relative to the air outlet position of the first blower fan 5 on dividing plate 11, the hole against fins group 3 and with the first wind
The air outlet of machine 5 is connected, while the both sides of housing 1 are respectively arranged with air inlet 14, and air-out is offered in the side wall of mixing chamber 13
Mouthfuls 15, so the first blower fan 5 to fins group 3 dry when, the cold wind sucked in from the air inlet 14 of both sides can be to scattered
Hot device 2 carries out first time cooling, while wind blows to fins group 3 by the first blower fan 5, and carrying out second to fins group 3 cools down, and warms up sky
Gas carries out part heat exchange in mixing chamber 13 so that temperature somewhat reduces.
In order that the gas discharged from mixing chamber 13 can be cooled down quickly, on the top of housing 1, positioned at the position of mixing chamber 13
Put and be provided with a hole, and the second blower fan 6 is installed on the top of housing 1, the air outlet alignment mixing chamber 13 of the second described blower fan 6
The hole on top, so by actively ventilating, it is sufficiently mixed cold and heat air.
It is a precision instrument in view of projecting apparatus, in order to ensure its service life, so air inlet 14 is directed at radiator
2, and a filter cotton 16 is installed respectively in the inner side of air inlet 14, for filtering the dust in the air sucked in, avoid
Dust is disturbed precision instrument.Because having used blower fan, just unavoidable meeting produces vibration, in order to reduce because blower fan shakes
Project and rock caused by dynamic, one layer of damping cotton is installed, and the first blower fan 5 selects axle stream between fan supporter 4 and dividing plate 11
Blower fan.One damping cotton is installed, and the second blower fan 6 uses axial flow blower between the second blower fan 6 and housing 1.Use axle stream wind
The reason for machine is because axial flow blower flow is big, pressure difference is small, is more suitable for such a occasion than centrifugal blower.
A heat-preservation cotton is also equipped with dividing plate 11, to reduce the heat transfer of mixing chamber 13 into operating room 12.
Operation principle：A kind of operation principle of projector radiating device of the present utility model be described above it is clear,
