However, with the continuous advancement of projector technology and the improvement of brightness, the heat generated by the internal projection module and other electronic components during operation is also increasing. If this heat cannot be effectively dissipated, it will cause the internal temperature of the projector to rise, which will affect the performance and life of the device.

[0003] Although heat dissipation is also taken into consideration in traditional projector optical and mechanical designs, it is often simply cooled by natural convection or a single fan, which lacks specificity and efficiency. Especially in high-brightness and long-term working scenarios, this traditional heat dissipation method often fails to meet the needs, easily causing the projector to overheat, performance degradation, or even equipment damage.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides a projector optical machine with an air duct optimized heat dissipation structure, such as Figure 1-Figure 2 As shown, it includes an upper cover 1 and a lower cover 2, which are fixed by bolts to facilitate installation and disassembly. A space is formed inside the upper cover 1 and the lower cover 2, and a projection module 8 is installed inside the space. A lens module 9 is installed on one side of the upper cover 1 and the lower cover 2. A first radiator 5 is installed on the side of one end of the projection module 8 close to the lens module 9. A first cooling fan 3 is installed on the outer side of the first radiator 5 for heat dissipation of the display screen area. A second radiator 6 is installed on the left and right sides of the projection module 8. A second cooling fan 4 and a third cooling fan 7 are respectively installed on the outer sides of the second radiator 6 for heat dissipation of the projection module 8.

[0021] In this embodiment, an upper slot 11 is provided on a side wall of the upper cover 1 close to the lens module 9 , and a lower slot 21 is provided on a side wall of the lower cover 2 close to the lens module 9 .

[0022] Specifically, a circular hole is formed between the upper card slot 11 and the lower card slot 21 , and the lens end of the lens module 9 passes through the circular hole, so as to facilitate the installation and positioning of the lens module 9 .

[0023] Furthermore, positioning grooves for placing the first cooling fan 3, the first radiator 5 and the second radiator 6 are installed on the inner sides of the upper cover 1 and the lower cover 2 to facilitate the installation and positioning of each component.

[0024] Furthermore, the second cooling fan 4 and the third cooling fan 7 are symmetrically fixed to the outer walls on both sides of the projection module 8 by bolts, so as to facilitate the installation and positioning of the second cooling fan 4 and the third cooling fan 7 .

[0025] Furthermore, the air outlets of the second cooling fan 4 and the third cooling fan 7 face the second radiator 6 to improve the heat dissipation effect of the second radiator 6, and the air inlets face the projection module 8 to ensure that the heat of the projection module 8 is extracted to perform a heat dissipation operation.

[0026] Furthermore, a display screen is installed between the projection module 8 and the lens module 9, and the air outlet of the first cooling fan 3 faces the display screen. The first cooling fan 3 is installed at an angle to improve the heat dissipation effect on the display screen.

[0027] Furthermore, the internal air ducts of the first cooling fan 3, the second cooling fan 4 and the third cooling fan 7 are fan-shaped structures, which optimizes the air duct structure.

[0028] When the projector optical machine with the air duct optimized heat dissipation structure of the utility model is used, first, the second radiator 6 is installed on both sides of the projection module 8, and the second heat dissipation fan 4 and the third heat dissipation fan 7 are equipped. The air inlets of the two fans are directly aimed at the projection module 8, and the air outlets are aimed at the second heat dissipation fan 6. When the projector is working, the second heat dissipation fan 4 and the third heat dissipation fan 7 are started at the same time, the heat generated by the projection module 8 is quickly extracted, and the heat is dissipated to the outside through the second heat dissipation fan 6, so as to ensure that the temperature of the projection module 8 is not too high.

[0029] Secondly, for the end of the projection module 8 close to the lens module 9, especially the display screen area, since this part is also a key area of ​​heat generation, a first radiator 5 and a first cooling fan 3 are specially installed. The first cooling fan 3 is installed at an angle, and its air outlet is directly aimed at the display screen. When the projector is working, the first cooling fan 3 will start, and the heat generated by the display screen will be extracted in time, and the heat will be dissipated through the first radiator 5 to ensure the stable operation of the display screen.

[0030] In addition, the utility model also improves the heat dissipation efficiency by optimizing the air duct structure. Specifically, the internal air ducts of the first heat dissipation fan 3, the second heat dissipation fan 4 and the third heat dissipation fan 7 all adopt a fan-shaped structure design. This design can increase the coverage of the wind flow and make the heat dissipation more uniform and efficient.

[0031] Finally, it should be noted that the electronic components of the projection module 8, lens module 9, etc. in this embodiment are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components are connected by wires respectively, and the specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the art.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model.

The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
