Description

Technical Field

[0001] The utility model relates to the technical field of thermal management, in particular to a novel cooling mechanism based on a projector. Background Art

[0002] The projector's new cooling mechanism is an innovative cooling system designed specifically for projectors. It uses advanced thermal management technologies such as heat pipes or liquid cooling to effectively reduce the projector's internal temperature and maintain stable operation. This mechanism also takes energy saving and noise control into consideration and may include an intelligent temperature control system that automatically adjusts the cooling effect to improve efficiency and extend lifespan, thereby optimizing the projector's performance and user experience.

[0003] In the prior art, conventional projectors use simple heat dissipation holes to ventilate and dissipate heat inside the projector. Simple heat dissipation holes cannot automatically discharge the hot air inside the projector and can only dissipate heat through normal air flow. However, they cannot completely discharge the hot air inside the projector and cannot achieve a heat dissipation and cooling effect inside the projector.

[0004] According to the structure of the existing technology, opening heat dissipation holes on the projector casing can only simply achieve the effect of heat dissipation, and can only discharge the internal hot air through natural air flow. It is impossible to completely discharge the internal hot air to achieve the effect of heat dissipation and cooling, resulting in poor heat dissipation and cooling effect, which does not meet the use requirements. Utility Model Content

A heat dissipation hole 15 is opened inside the heat dissipation box 14, and a cooling pipe 16 is fixedly connected to the inside of the heat dissipation box 14;

[0026] Specifically, the mounting plate 1 is mounted on the upper surface of the heat-conducting aluminum bracket 4 through the connecting shaft 6, and the double-sided air intake fan 5 is mounted on the lower surface of the heat-conducting aluminum bracket 4. The double-sided air intake fan 5 is started to extract the hot air inside the projector, and the hot air is conducted into the inside of the double-sided air intake fan 5 through the heat-conducting aluminum bracket 4. The double-sided air intake fan 5 can also transport the external cold air into the interior of the projector. After the hot air enters the inside of the double-sided air intake fan 5, it is discharged into the interior of the heat dissipation box 14 through the air outlet 17. The hot air is cooled by the internal cooling pipe 16 of the heat dissipation box 14 and then discharged through the heat dissipation holes 15. The cold air enters the interior of the projector through the air inlet 13 inside the double-sided air intake fan 5 and flows, and then combines with the cooling pipe 16 to cool the outside of the projector, thereby achieving a multi-directional heat dissipation and cooling effect.

[0027] Reference Figure 1 - Figure 2 The upper surface of the heat-conducting aluminum bracket 4 is fixedly connected with a mounting shaft 8, and the upper surface of the mounting shaft 8 is fixedly connected with a driving plate 2. The upper surface of the heat-conducting aluminum bracket 4 is provided with an optical-mechanical assembly 3, which is used to project a film. The optical-mechanical assembly 3 is arranged at the front end of the heat-conducting aluminum bracket 4. The optical-mechanical assembly 3 includes a projection lens 9, which is fixedly connected to the upper surface of the heat-conducting aluminum bracket 4. The upper surface of the heat-conducting aluminum bracket 4 is fixedly connected with a connecting plate 10;

[0028] Specifically, the driving board 2 is installed at the rear end of the upper surface of the thermally conductive aluminum bracket 4 through four mounting shafts 8, and the optical-mechanical assembly 3 is installed at the front end of the thermally conductive aluminum bracket 4, the projection lens 9 is fixed on the upper surface of the thermally conductive aluminum bracket 4, and the connecting plate 10 is fixed on the upper surface of the thermally conductive aluminum bracket 4. The thermally conductive aluminum bracket 4 can conduct the heat generated by the optical-mechanical assembly 3, conduct the heat to the thermally conductive aluminum bracket 4 and achieve the heat dissipation and cooling effect by cooling the thermally conductive aluminum bracket 4, thereby assisting in cooling the projector.

[0029] Reference Figure 1 and Figure 5 The outer wall of the connecting plate 10 is fixedly connected to a power connection block 11, which is arranged on both sides of the outer wall of the connecting plate 10.

The lower surface of the mounting plate 1 is fixedly connected to the connector 7, and the cooling pipe 16 is fixedly connected to the outer wall of the connecting plate 10;

[0030] Specifically, the two power connection blocks 11 are fixedly connected to both sides of the outer wall of the connecting plate 10, and the power cord is connected to the power supply and the projection device through the two power connection blocks 11 and the connector 7. The film to be projected is projected through the projection lens 9 through the controller 12. The heat generated by the controller 12 and the projection lens 9 during operation is conducted through the heat-conducting aluminum bracket 4 to discharge the heat generated by the controller 12 and the projection lens 9, thereby assisting in achieving the heat dissipation effect. Then, the cooling liquid is added through the cooling pump connected to the cooling pipe 16, and the cooling pipe 16 is used to cool the entire exterior of the projector.

[0031] Working principle: When it is necessary to use the new cooling mechanism of the projector, first combine the cooling mechanism and the projector for installation, install the double-sided air inlet fan 5 on the lower surface of the heat-conducting aluminum bracket 4, install the heat dissipation box 14 on the outer wall of the double-sided air inlet fan 5 and fit it to the position of the air outlet 17, install the optical machine component 3 on the front end position of the upper surface of the heat-conducting aluminum bracket 4, install the drive board 2 on the rear end position of the upper surface of the heat-conducting aluminum bracket 4, and finally install the mounting plate 1 on the upper surface of the heat-conducting aluminum bracket 4 and higher than the drive board 2 and the optical machine component 3, connect the power cord and the device connection cable through the connector 7 and the power connection block 11, start the projector, and project the film through the device control controller 12. The controller 12 projects the film through the projection lens 9. The controller 12 and the projection lens 9 are prone to generate a lot of heat during operation. The hot air is discharged to the inside of the heat sink 14 through the air outlet 17 inside the double-sided air inlet fan 5. The hot air is cooled by the cooling pipe 16 and then the external part of the projector is cooled. The hot air in the heat sink 14 is cooled by the cooling pipe 16 and then discharged. The double-sided air inlet fan 5 transports the cold air upward from the bottom through the air inlet 13 to the inside of the projector for heat dissipation, thereby achieving the effect of discharging the internal hot air through air flow.
