Specific embodiment
It is noted that following detailed description is all illustrative, it is intended to provide further instruction to the application.It is unless another
It indicates, all technical and scientific terms used herein has usual with the application person of an ordinary skill in the technical field
The identical meanings of understanding.
It should be noted that term used herein above is merely to describe specific embodiment, and be not intended to restricted root
According to the illustrative embodiments of the application.As used herein, unless the context clearly indicates otherwise, otherwise singulative
It is also intended to include plural form, additionally, it should be understood that, when in the present specification using term "comprising" and/or " packet
Include " when, indicate existing characteristics, step, operation, device, component and/or combination thereof.
To achieve the above object, the specific technical solution of the utility model is as follows：
The present embodiment is by taking two air inlets and three air outlets as an example：
Radiator for laser display wall as shown in Figure 1 has left and right two in DLP laser display wall housing upper surfaces
A air inlet, in DLP laser display wall housings or so face and lower surface, respectively there are one air outlets；Air inlet and air outlet by point
The collection of several apertures of the cloth on DLP laser display walls housing 12 is combined into；The size of air inlet is more than air outlet size；Into
Induced draught fan I 1 and induced draught fan II 3 are equipped at air port, air ejector fan I 5 is equipped at the air outlet of the right side, in lower surface air outlet
Place is equipped with air ejector fan II 7, and air ejector fan III 11 is equipped at the air outlet of the left side；The air outlet of air ejector fan II 7 and air draught wind
Fan I 1 air inlet center line it is coaxial, the top of air ejector fan II 7 is equipped with heat-pipe radiator 8, the air outlet of air ejector fan III 11
Adjacent with the laser module 9 of DLP laser displays within the walls, the air outlet of air ejector fan I is adjacent with light source driver module 6, air draught wind
Fan II 3 air inlet it is adjacent with power module 4.
The specific radiation processes of the present apparatus are as follows：
Rise the principle of cold air decline according to hot-air, inhaled after being declined by the cold air of I 1 inspiration of induced draught fan to being located at
Laser Power Devices module 10 and bare engine module 2 below wind fan I 1 are cooled down, and the hot gas distributed by laser module 9 rises to row
It near wind fan III 11, is discharged through air ejector fan III 11 through exhaust outlet and shows wall housing, the air for having little time discharge continues to decline
After divide two-way, all the way through the heat-pipe radiator of lower part of the housing 8 heat dissipation after through air ejector fan II 7 through exhaust outlet discharge show wall shell
Body, another way to be located at the light source driver module 6 near housing bottom continue cooling heat dissipation, then through air ejector fan I 5 from
Exhaust outlet discharge shows wall housing.
Induced draught fan II 3 also is located at the upper surface of display wall housing 12, will be cold after cool ambient air sucking display wall housing
Since gravity decline carries out cooling heat dissipation to power module 4 and bare engine module 2, the air after heat exchange continues to decline air,
Light source driver module 6 with being aligned together near housing bottom after being declined by the cold air of I 1 inspiration of induced draught fan is cooled down
Then heat dissipation discharges from exhaust outlet through air ejector fan I 5 and shows wall housing.
The setting quantity of air inlet and induced draught fan and exhaust outlet and air ejector fan can be according to the size of display wall housing
Setting, is not limited only to the quantity enumerated in the present embodiment.
Above-mentioned, although the foregoing specific embodiments of the present invention is described with reference to the accompanying drawings, not protects model to the present invention
