Fan group, to radiate to heat caused by projector inside；Since air inlet and air outlet are oppositely arranged, distinguished and admirable resistance
Greatly, long flow path, it is therefore desirable to which the fan group of relatively high power not only expends electric energy, and can generate biggish noise, especially family
Close with projector's instrument placement location and user distance, influence of the noise that radiator fan is issued to projection user is very big.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of good heat dissipation effects, and brightness of image is high, can save energy and drop
The household Single panel LCD vertical projector to make an uproar.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
The LED light emitting source of bottom in square shell is arranged in a kind of Single panel LCD vertical projector, including square shell, with
And the hot device of fan in square shell and being located on the left of LED light emitting source is set, the LED light emitting source upper horizontal is provided with imaging
LCD screen is equipped with refraction film mirror above the imaging LCD screen, and the side of the imaging LCD screen is equipped with radiator fan,
The inner wall of the square shell and close to refraction the film mirror side force(d) (draft) fan is installed.
Preferably, camera lens is installed at the top of the square shell, the square shell is equipped with and leans against on camera lens
Reflecting mirror.
Preferably, air inlet is offered at the top of the square shell, the bottom of the square shell offers air outlet.
Preferably, the inner wall of the square shell and be located at force(d) (draft) fan below be equipped with master signal processing PCB.
By adopting the above technical scheme, since the utility model is that air inlet setting is rectangular in Single panel LCD vertical projector
Upper part of the housing, air outlet setting are imaged LCD screen and are had at high temperature there is a situation where discoloration (blank screen) in mode housing bottom,
The necessary rapid cooling of LCD screen is imaged, Homogeneouslly-radiating, distinguished and admirable necessary distinguished and admirable big in imaging LCD screen, process short (from A to B) passes through
Force(d) (draft) fan and radiator fan work together, can reduce distinguished and admirable resistance, increase distinguished and admirable flow, and shortening is distinguished and admirable to be imaged LCD screen
Process enhances the heat sinking function to internal heat, can both reduce the power of radiator fan in this way, improves projector brightness of image,
Play the role of energy-saving and noise-reducing.

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
In the present embodiment, a kind of Single panel LCD vertical projector, as shown in Figure 1, the bottom in square shell 1 is provided with
LED light emitting source 2 is provided with the hot device 3 of fan in square shell 1, and radiator 3 is located at the left side of LED light emitting source 2, in LED light emitting source
2 be that upper horizontal is provided with imaging LCD screen 4, refraction film mirror 5 is equipped in the top of imaging LCD screen 4, in imaging LCD screen 4
Side radiator fan 7 is installed, force(d) (draft) fan 8 is installed in the outer wall of square shell 1, and force(d) (draft) fan 8 is luxuriant and rich with fragrance close to refraction
5 side of woods mirror.
As shown in Figures 2 and 3, all internal original part of projector is all Gao Fare, and machine needs quickly heat dissipation, internal imaging
LCD screen 4 at high temperature will blank screen, imaged color lose, in the present embodiment, force(d) (draft) fan 7 is by air from square casing 1
Portion's sucking pushes among refraction film mirror 5, passes through from imaging 4 upper and lower surface of LCD screen, and inner air passes through imaging LCD from the end A
The end B of screen 4, radiator fan 7 be dischargeds by radiator 3 from rectangular 1 body bottom of shell, force(d) (draft) fan 8 and radiator fan 7 work simultaneously
Make, such design can increase air inlet/outlet area, improve the flow of radiating airflow, keep the heat assembled in imaging LCD screen 4 fast
Speed sheds, meanwhile, such design shortens stroke of the air in imaging LCD screen 4, and the temperature for being conducive to be imaged LCD screen 4 is equal
