[0002] Projectors are widely used in modern multimedia teaching, conference presentations, and home theaters. However, as the continuous working time of the projector increases, key components such as the internal display screen will generate a lot of heat. If this heat cannot be dissipated in a timely and effective manner, it will have a negative impact on the performance of the device and may even damage the hardware. Traditional projector designs usually rely on natural convection and simple heat dissipation systems inside the device for cooling, but under high load or long-term operation, this heat dissipation method often cannot meet the needs. Therefore, the development of a projector optical machine that can effectively reduce the temperature of the display screen has become an urgent need in the industry. Utility Model Content

[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 which is convenient for cooling a display screen. Figure 1-Figure 2 As shown, it includes an upper cover 1 and a lower cover 2, an internal space is formed between the upper cover 1 and the lower cover 2, a display screen 3 is installed inside the internal space, a lens 4 is installed on one side of the upper cover 1 and the lower cover 2, a first radiator 6 is installed on the outer side of the back of the display screen 3, a first fan 7 is installed on the outer side of the first radiator 6, a second radiator 8 is installed below the display screen 3, a second fan 9 is installed on the outer side of the second radiator 8, and an auxiliary radiator 10 is installed near the second fan 9 of the lower cover 2. The display screen 3 is safely placed in this internal space. It is the core component of the projector and is responsible for projecting the image. In order to ensure the quality of projection, a lens 4 is specially installed on the outer side of one side of the upper cover 1 and the lower cover 2, so that the clarity and accuracy of the projection can be ensured. However, considering that the display screen 3 and other electronic components of the projector will generate a lot of heat after long-term use, the heat dissipation design becomes particularly critical. In order to effectively solve this problem, the utility model specially installs a first radiator 6 on the outer side of the back of the display screen 3. This radiator can quickly conduct the heat generated by the display screen. In order to further accelerate the dissipation of heat, the outer side of the first radiator 6 is specially equipped with a first fan 7 to quickly take away the heat through forced convection. In addition, the utility model also sets a second radiator 8 below the display screen 3, which works in conjunction with the first radiator 6 to form an all-round heat dissipation system. A second fan 9 is also installed on the outer side of the second radiator 8 to ensure the timely discharge of heat. It is particularly worth mentioning that in order to further enhance the heat dissipation effect, the lower cover 2 is also specially equipped with an auxiliary radiator 10 near the second fan 9. This design not only increases the heat dissipation area, but also can provide strong support for the main radiator when the projector is working at high load, ensuring the stable operation of the entire system.

[0021] In this embodiment, a light board 5 is installed on the back of the display screen 3 , and the light board 5 is installed on the outer wall of the first heat sink 6 by bolts, so as to facilitate the positioning of the light board 5 .

[0022] Specifically, the air inlet of the second fan 9 faces the second radiator 8, and the air outlet is connected to the internal space, so as to dissipate the heat in time.

[0023] Furthermore, the auxiliary radiator 10 includes an arc-shaped plate 101 , and a plurality of heat dissipation fins 102 are installed on the outer side of the arc-shaped plate 101 to improve the heat dissipation effect of the auxiliary radiator 10 .

[0024] Furthermore, the air outlet of the first fan 7 faces the first radiator 6 , which facilitates cooling of the first radiator 6 .

[0025] Furthermore, a plurality of positioning grooves are provided on the lower cover 2 to respectively fix the first radiator 6 , the first fan 7 , the second radiator 8 and the second fan 9 , so as to facilitate the installation and positioning of each component.

[0026] Furthermore, the first heat sink 6 and the second heat sink 8 are both composed of a multi-layer heat sink structure, which increases the contact area with the air and improves the heat dissipation effect.

[0027] Furthermore, the upper cover 1 and the lower cover 2 are both integrally formed structures, which improves the strength of the upper cover 1 and the lower cover 2 and avoids damage caused by long-term use. The upper cover 1 and the lower cover 2 are fixed by bolts, which facilitates installation and disassembly between the upper cover 1 and the lower cover 2.

[0028] When the projector optical machine of the utility model is used to cool the display screen, the display screen 3 is the core component responsible for generating and projecting images. In order to ensure the clarity and accuracy of the projection, the image is accurately projected through the lens 4 installed on one side of the upper cover 1 and the lower cover 2.

[0029] During the operation of the projector, the display screen 3 and other electronic components will generate heat. In order to effectively dissipate heat, the utility model adopts a multiple heat dissipation design. First, the first radiator 6 installed on the outer side of the back of the display screen 3 can quickly conduct the heat generated by the display screen. The first radiator 6 adopts a multi-layer heat sink structure, which increases the contact area with the air and improves the heat dissipation effect. At the same time, the first fan 7 quickly takes away the heat on the first radiator 6 through forced convection, further accelerating the heat dissipation.

[0030] In addition, the second radiator 8 installed below the display screen 3 works in conjunction with the first radiator 6 to form an all-round heat dissipation system. The second radiator 8 also adopts a multi-layer heat sink structure, and the second fan 9 installed on the outside ensures timely discharge of heat. In particular, the air inlet of the second fan 9 faces the second radiator 8, and the air outlet is connected to the internal space. Such a design allows heat to be dissipated more efficiently.

[0031] In order to further enhance the heat dissipation effect, the lower cover 2 is also specially equipped with an auxiliary radiator 10 near the second fan 9. The auxiliary radiator 10 is composed of an arc plate 101 and a plurality of heat dissipation fins 102. Such a design not only increases the heat dissipation area, but also provides strong support for the main radiator when the projector works at high load.

[0032] Finally, it should be noted that the electronic components of the display screen 3, light board 5, 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 part 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.
