The present invention proposes a kind of projector 100.
Referring to figs. 1 to 2, in embodiments of the present invention, which includes:
Shell 10, shell 10 include side wall and the accommodating chamber surrounded by side wall, and side wall offers the resigning of connection accommodating chamber
Mouth 11；
Lens assembly 50, lens assembly 50 are embedded at resigning mouthful 11；
Light source 20, light source 20 are installed on accommodating chamber；
Light modulation element 30 and heat-exchanging component 40, Light modulation element 30 and heat-exchanging component 40 are installed in accommodating chamber, and light
Modulation component 30 and heat-exchanging component 40 are arranged side by side and accommodating chamber are separated to form the first accommodating chamber 12 and the second accommodating chamber 13, the
One accommodating chamber 12 is closed, and the second accommodating chamber 13 is in communication with the outside, and resigning mouthful 11 is connected to the first accommodating chamber 12；
Wherein, the heat of the first accommodating chamber 12 is exchanged to the second accommodating chamber 13 by heat-exchanging component 40, and heat holds by second
Chamber 13 of receiving is transferred to the external world.
Specifically, 10 shape of shell of the application can be in cuboid, and the first accommodating chamber 12 is connected with the second accommodating chamber 13,
Light source 20 is installed in the second accommodating chamber 13, and is bonded 10 side wall of shell and is fixedly connected, and light source 20 is chosen as LCD lamp, light source 20
The light of sending is projected in external screen after being modulated by Light modulation element 30 by camera lens 52.
Technical solution of the present invention is by using 100 shell 10 of projector and heat-exchanging component 40, the cooperation of Light modulation element 30
Sealing space is set by space locating for the image device of projector 100, to avoid dust in 100 course of work of projector poly-
The problem of collecting on image device, influencing display brightness and clarity, good dust-proof effect is played, heat-exchanging component is furthermore passed through
40 also effectively dissipate the heat in confined space in time, to guarantee that heat will not influence the normal operation of other devices.
Further, referring to Fig. 3, heat-exchanging component 40 includes refrigeration silicon wafer 41 and two multilayer fins, is freezed 41 liang of silicon wafer
End is respectively refrigeration end and fever end, and two multilayer fins are connected to refrigeration end and the fever end of the refrigeration silicon wafer 41,
The multilayer fin connecting with refrigeration end is located at the first accommodating chamber 12, and refrigeration silicon wafer 41 and the multilayer fin connecting with fever end are located at
Second accommodating chamber 13.
Specifically, by the way that in electromagnetic transmission to silicon wafer, according to pyroelectric effect, the silicon wafer 41 that freezes is sent out when freezing
Heat, multilayer fin are that a fixed plate and multiple fins are integrally formed, and fin material can be aluminum material, pass through two screw brackets 44
With the cooperation of screw, two multilayer fins are connect with the two sides of refrigeration silicon wafer 41 respectively, such two multilayer fins are respectively
Refrigeration end multilayer fin 42 and fever end multilayer fin 43, refrigeration end multilayer fin 42 are in the first accommodating chamber 12, and refrigeration end is more
Layer 42 fixed plate of fin and the cooperation of Light modulation element 30 and shell 10 make 12 confined space of the first accommodating chamber, the heat of confined space
Amount is transferred to the second accommodating chamber 13 by heat-exchanging component 40, and is transferred to external environment by the second accommodating chamber 13.Further,

Display screen 32 separates in the first accommodating chamber 12.
Specifically, preceding luxuriant and rich with fragrance mirror 31 and rear luxuriant and rich with fragrance mirror 33 are all Fresnel Lenses, and one piece of display is equipped between front and back phenanthrene mirror 33
Screen 32, rear phenanthrene mirror 33 separates preceding luxuriant and rich with fragrance mirror 31 and display screen 32 in the first accommodating chamber 12, after the light that light source 20 issues first passes through
Luxuriant and rich with fragrance mirror 33, rear phenanthrene mirror 33 play scattering light action, light are uniformly projected on the display screen 32, later, pass through 32 light of display screen
For line before being radiated on luxuriant and rich with fragrance mirror 31,32 picture of display screen that preceding phenanthrene mirror 31 then bright colors will be presented by light reassembles camera lens
On 52.
Further, referring to Fig. 5, projector 100 further includes a heat-protecting glass 60, the luxuriant and rich with fragrance mirror 33 after being installed on of heat-protecting glass 60
Between display screen 32.Specifically, because luxuriant and rich with fragrance mirror 33 irradiates on the display screen 32 for a long time after the light warp of light source 20, so that aobvious
The temperature of display screen 32 is excessively high, though cooled down by heat-exchanging component 40, in order to further decrease 32 temperature of display screen, in display screen 32
One block of heat-protecting glass 60 is installed between rear luxuriant and rich with fragrance mirror 33, which can absorb the partial heat of light source 20.
Further, referring to Fig.1, projector 100 further includes a reflecting mirror 70, and the reflecting mirror 70 is installed on described first
In accommodating chamber 12, the lens assembly 50 will be reflected by the light of Light modulation element 30.Specifically, in order to avoid projection
100 shell 10 of instrument is too big, and bad installation is equipped with a reflecting mirror 70 in the first accommodating chamber 12, which will pass through light
The light of modulation component 30 is reflected on lens assembly 50.
Further, referring to Fig. 6, lens assembly 50 is including a fixed bracket 51, the camera lens 52 connecting with fixed bracket 51,
And camera lens 52 is connected to close to the sealing ring 53 of the end of the first accommodating chamber 12, fixed bracket 51 is fixedly connected on resigning mouthful 11
It is interior.
Specifically, fixed bracket 51, which is connected by screw to, is fixed in resigning mouthful 11, is equipped with screw thread on the inside of fixed bracket 51,
