[0002] The liquid crystal display module is an electronic component used to display images and text. It is mainly composed of a liquid crystal screen, a backlight module, a driver IC and a control IC. The heat dissipation mechanism design of the liquid crystal display module is crucial to ensure its stable operation and extend its service life. The heat dissipation mechanism is mostly made of a heat sink and heat dissipation fins, which can utilize its own thermal conductivity to absorb the heat of the liquid crystal display module and achieve a heat dissipation effect.

[0003] The heat dissipation mechanism is often equipped with a heat sink and heat fins. The heat can be absorbed through the contact between the heat sink and the back of the liquid crystal display module. However, due to the limited area of ​​the heat sink, the range of heat absorption is relatively limited, which slows down the heat dissipation speed of the liquid crystal display module. In addition, the heat absorbed by the surface of the heat sink fin cannot be quickly dissipated into the air, reducing the efficiency of the heat dissipation mechanism. Therefore, it is particularly important to design a heat dissipation mechanism for the liquid crystal display module. Utility Model Content

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4As shown, one side of the two second heat conducting plates 9 is fixedly connected to one side of the first heat conducting plate 2, and a plurality of copper bars 10 are fixedly mounted on the surfaces of the two second heat conducting plates 9, respectively. The positions where the plurality of copper bars 10 are arranged are arranged at equal intervals. The utility model provides a heat dissipation mechanism for a liquid crystal display module. By setting a positioning block 4, a screw 13, a nut 14 and a heat dissipation groove 5, after the bottom surface of the side plate 11 is fitted with the surface of the L-shaped block 12, the screw 13 itself limits the inside of the L-shaped block 12.

[0026] Working principle: Liquid crystal display module is an electronic component used to display images and texts. It is mainly composed of a liquid crystal screen, a backlight module, a driver IC and a control IC. The heat dissipation mechanism design of the liquid crystal display module is crucial to ensure its stable operation and extend its service life. The heat dissipation mechanism is mostly installed with a heat sink 1 and heat dissipation fins 3. It can use its own thermal conductivity to absorb the heat of the liquid crystal display module and achieve the effect of heat dissipation. The heat sink 1 is installed on the back of the liquid crystal display module. At this time, the back of the heat sink 1 and multiple copper bars 10 will contact the back of the liquid crystal display module. The heat dissipation fan 6 rotates through the motor, which can dissipate the heat absorbed by the surface of the heat dissipation fins 3 more quickly into the air. The heat sink 1 and one side of the multiple copper bars 10 are tightly attached to the back of the liquid crystal display module. Through their large surface area and excellent thermal conductivity, they effectively absorb and disperse the heat generated by the module. The heat sink 1 and the two second heat conducting plates 9 are made of aluminum alloy materials. The heat sink 1, the second heat conducting plate 9 and the copper bars 10 have good thermal conductivity and mechanical strength, which can ensure the stability and durability of the heat dissipation effect and improve the heat dissipation. The heat dissipation efficiency of the mechanism is improved. The dustproof net 8 can block external dust and impurities, preventing dust and impurities from entering the interior of the cooling fan 6 and affecting the quality of heat dissipation. After the first heat conducting plate 2 is embedded in the interior of the heat dissipation plate 1, the bottom surfaces of the two side plates 11 are respectively fitted with the surfaces of the L-shaped blocks 12, and then the two nuts 14 are sleeved on one end of the screw 13. The heat dissipation plate 1 and the first heat conducting plate 2 can be disassembled and cleaned through the two screws 13. After the bottom surface of the side plate 11 is fitted with the surface of the L-shaped block 12, the screw 13 itself limits the interior of the L-shaped block 12. After the two are fitted, The screw 13 will also be embedded in the inside of the side panel 11, and the nut 14 and the screw 13 are threaded together, so that the side panel 11 and the L-shaped block 12 can be limited and fixed, ensuring the firmness of the installation of the first heat conducting plate 2 and the heat sink 1. The positioning block 4 and the bolt can install the heat sink 1 and the back of the liquid crystal display module. When the cooling fan 6 is working, the heat inside the liquid crystal display module can form convection with the outside air through multiple heat dissipation grooves 5, thereby accelerating the heat dissipation speed. The design of the heat dissipation fins 3 increases the heat dissipation area, so that the heat can be dissipated into the air more quickly.
