[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] A highly efficient heat dissipation enclosed projector, such as Figure 1 As shown, the enclosed projector includes an upper housing 1 and a lower housing 2. The upper housing 1 and the lower housing 2 are fastened together and fixed by bolts. A lens module is installed at one end of the upper housing 1 (the lens module is not shown in the figure), and a heat sink 3 is fixedly installed at the other end. A light cover 5 is fixedly installed inside the heat sink 3. A screen module 4 is fixedly installed between the upper housing 1 and the lower housing 2.

[0027] like Figures 2-5 As shown, an air intake arc 7 and an air outlet arc 8 are fixedly provided inside the lower housing 2 and on both sides of the screen module 4, respectively. A cooling fan 6 is fixedly installed at one end of the air intake arc 7. The air outlet of the cooling fan 6 faces the air intake arc 7, and its air inlet faces the inside of the lower housing 2. It is used to draw in the air at the front end of the screen module 4 and then discharge it into the air intake arc 7. After being guided by the air intake arc 7, the air leaves out between the multiple screens of the screen module 4 to dissipate heat from the screen and the lens.

[0028] One end of the air outlet arc 8 faces the screen module 4, and the other end is fixedly installed with heat dissipation fins 9. One side of the heat dissipation fins 9 is located on the outside of the upper housing 1, and the other side is located at the air outlet end of the air outlet arc 8, so that the heat in the gas blown out from the screen module 4 is absorbed and dissipated to the outside of the projector. The inside of the projector is in a closed state, and the gas will not enter, ensuring that the components inside the projector work stably and that there will be no dust or moisture damaging the components.

[0029] A protective shell 10 is fixedly installed on the outside of the screen module 4. The protective shell 10 fixes the screen module 4. Gas flows in from one side of the protective shell 10 and flows out from the other side of the protective shell 10. One end of the photomask 5 faces the screen module 4, and the other end is fixedly equipped with a light source 11. The light source 11 is fixedly installed inside the heat dissipation cover 3. The heat dissipation cover 3 has mounting slots 12 on both sides. The mounting slots 12 can be used to install external fans to dissipate heat from the light source 11 and the outside of the photomask 5, ensuring the heat dissipation efficiency of the projector.

[0030] Mounting plates 13 are fixedly connected to one side of both the upper housing 1 and the lower housing 2. The heat dissipation fins 9 extend out of the upper housing 1 and are located between the two mounting plates 13. The heat dissipation fins 9 are fixed by the two mounting plates 13.

[0031] The working principle is as follows:

[0032] In this embodiment, the light source 11 emits light to project images, which then passes through the light cover 5. After passing through the screen module 4, the light is directly output from the lens module to project the image.

[0033] During the projection process, the heat generated by the light source 11 and the photomask 5 is dissipated from inside the heat sink 3, thus dissipating the heat generated by the light source 11 and the photomask 5 externally.

[0034] As for the screen module 4 located inside the projector, the heat is dissipated and evaporated from the heat dissipation fins 9 on one side of the projector through an internal circulation heat dissipation method. This closed circulation ensures that the air inside the upper shell 1 and the lower shell 2 is stable, preventing the absorption of external air and avoiding the probability of dust and moisture entering the projector. This improves the heat dissipation efficiency of the closed projector, achieves efficient heat dissipation, and ensures the working stability of the projector.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
