Abstract
The utility model discloses a light leakage free heat radiation hood for projector, which has two heat radiation and ventilation fins and one fastener, wherein, one heat radiation and ventilation fin is snapped into the rear plate of the projector rack, another fin is connected with the ahead fin through the fastener and placed in the projector rack. The included angle between each heat radiation and ventilation fin is less than or equal to 30 degrees and a small part at the edge of every two grates are belong to the same plane, moreover, the directions of the two heat radiation and ventilation fins are reverse. By adopting the projector, no light leaked from the ventilation port of the heat radiation and no influence to the heat radiation effect, thereby thoroughly solving the problem of light leakage from the projector heat radiation and the ventilation port.
Description
Technical field
The utility model relates to a kind of no light leak heat dissipation air hood of projector.
Background technology
In existing projector, the light leak problem in projector heat radiation air port never is resolved.Some projector directly is used as the air port of dispelling the heat in the case backboard upper shed, some projectors adopts a slice to have the heat radiator that oblique lattice delete and is used as the air port of dispelling the heat, no matter adopt above-mentioned which kind of mode, the light in projector's cabinet all can leak out, and just what are different.Because this light is very strong, easily eyes are produced spread effect, be unfavorable for that also the people of projector back watches project content, so need the no light leak technology in a kind of projector heat radiation air port.
Summary of the invention
The purpose of this utility model is to provide the heat radiation air port of a kind of no light leak heat dissipation air hood of energy efficiently radiates heat as projector.
The utility model is achieved in that
The heat dissipation air hood of projector is made of two heat dissipation ventilation sheets and a securing member, and one of them heat dissipation ventilation sheet is installed in projector's case backboard, and another heat dissipation ventilation sheet is connected with the heat dissipation ventilation sheet of front by securing member and places in projector's cabinet.Lattice on each heat dissipation ventilation sheet are deleted and the angle of heat dissipation ventilation sheet all is less than or equal to 30 degree and per two lattice edge between deleting and has fraction to belong to a surface level together, and simultaneously, it is opposite that the lattice of two heat dissipation ventilation sheets are deleted direction.Because the effect that the lattice of heat dissipation ventilation sheet are deleted, light in projector's cabinet after by first heat dissipation ventilation sheet just only remaining obliquely or that part of light under oblique, this part light is by second heat dissipation ventilation sheet the time, because it is opposite that the lattice of two heat dissipation ventilation sheets are deleted direction, so be blocked in entirely between two heat dissipation ventilation sheets.Like this, the light in projector's cabinet just has been blocked in projector's cabinet entirely.Simultaneously, owing between two heat dissipation ventilation sheets enough spaces are arranged, guaranteed that hot blast smoothly by the entire heat dissipation fan housing, can not influence the radiating effect of projector.
The beneficial effects of the utility model are:
Thoroughly solved the problem of projector heat radiation ventilating opening light leak and can not influence the radiating effect of projector, the visual impact when having avoided light in projector's cabinet to watch project content to the stimulation injury of people's eyes and skin with to the people of projector back.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model;
Fig. 3 is that one of sectional view is looked on a left side of the present utility model;
Fig. 4 be a left side of the present utility model look sectional view two.
Wherein, 1 projector's case backboard, 2 heat dissipation ventilation sheets, the lattice of 3 heat dissipation ventilation sheets are deleted, 4 securing members.
Embodiment
Below in conjunction with accompanying drawing the utility model is done concrete description:
As depicted in figs. 1 and 2, the heat dissipation air hood of projector is made of two heat dissipation ventilation sheets 2 and a securing member 4, one of them heat dissipation ventilation sheet 2 is installed on projector's case backboard 1, and another heat dissipation ventilation sheet 2 is connected with the heat dissipation ventilation sheet 2 of front by securing member 4 and places in projector's cabinet.As shown in Figure 3 and Figure 4, the lattice of each heat dissipation ventilation sheet delete 3 and the angle of heat dissipation ventilation sheet 2 all be less than or equal to the edge that the lattice of 30 degree and per two heat dissipation ventilation sheets delete between 3 and have fraction to belong to a surface level together, simultaneously, to delete 3 direction opposite for the lattice of the heat dissipation ventilation sheet of two heat dissipation ventilation sheets 2.Because the lattice of heat dissipation ventilation sheet are deleted 3 effect, light in projector's cabinet is just only remaining obliquely or that part of light under oblique by first heat dissipation ventilation sheet, 2 backs, this part light is by second heat dissipation ventilation sheet 2 time, because it is opposite that the lattice of two heat dissipation ventilation sheets are deleted 3 direction, so be blocked in entirely between two heat dissipation ventilation sheets 2.Like this, the light in projector's cabinet just has been blocked in projector's cabinet entirely.Simultaneously, owing to the securing member 4 between two heat dissipation ventilation sheets 2 has guaranteed between two heat dissipation ventilation sheets 2 enough spaces are arranged, and the heat dissipation ventilation sheet is very smooth, has guaranteed that hot blast smoothly by the entire heat dissipation fan housing, can not influence the radiating effect of projector.
Of the present utility model focusing on to projector provides the heat dissipation ventilation cover that comprises two heat dissipation ventilation sheets and a securing member if only change the connected mode of its mounting means or securing member and heat dissipation ventilation sheet, all should be considered as infringement.
Claims (4)
1, a kind of no light leak heat dissipation air hood of projector, comprise two heat dissipation ventilation sheets and a securing member, it is characterized in that: a heat dissipation ventilation sheet is installed in projector's case backboard, and another heat dissipation ventilation sheet is connected with the heat dissipation ventilation sheet of front by securing member and places in projector's cabinet;
