Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid crystal display technology, and in particular to a heat dissipation structure for a liquid crystal display. Background Technology
[0002] LCD screens are a type of flat panel display used in televisions and computers. Their advantages include low power consumption, small size, and low radiation. However, LCD screens generate a lot of heat during operation, requiring a heat dissipation structure to ensure the normal operation of the device.
[0003] Among them, the utility model patent with announcement number CN217544099U discloses a heat dissipation structure for liquid crystal displays. However, although the above patent achieves heat absorption and dissipation of the display, the heat absorption and heat dissipation amount is easy to reach saturation when absorbing and dissipating heat for a long time, and it does not have the effect of external auxiliary cooling, thus making it difficult for the liquid crystal display to dissipate heat efficiently. Therefore, we propose a heat dissipation structure for liquid crystal displays to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a heat dissipation structure for a liquid crystal display screen to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A heat dissipation structure for a liquid crystal display screen includes a back cover of the display screen. Two sets of heat dissipation fins are fixedly embedded on the back of the back cover of the display screen. The front ends of the two sets of heat dissipation fins are connected to a heat-absorbing copper plate. A thermally conductive silicone pad is connected to the front of the heat-absorbing copper plate. An exhaust fan is fixedly embedded on the back of the back cover of the display screen. A cooling component is fixedly embedded on the bottom surface of the back cover of the display screen. The cooling component includes a cooling box. A semiconductor cooling chip is fixedly embedded on the bottom surface of the cooling box. The cooling end of the semiconductor cooling chip is located inside the cooling box. A set of vents is opened on the front of the cooling box. A drying filter is fixedly embedded on the upper surface of the cooling box.
[0007] In a further embodiment, a protective gasket is connected to the front of the back cover of the display screen, and the protective gasket is made of rubber.
[0008] In a further embodiment, the front of the display screen back cover is provided with two sets of mounting holes, and each mounting hole is fitted with a mounting screw on its inner wall.
[0009] In a further embodiment, grip handles are connected to both the left and right sides of the back cover of the display screen, and an anti-slip sleeve is connected to the outer surface of each grip handle.
[0010] In a further embodiment, each of the heat dissipation fins has a set of heat dissipation holes on its outer surface, and the heat dissipation holes are elliptical.
[0011] In a further embodiment, a model mark is provided on the upper surface of the display screen back cover, and the model mark is located in the middle of the display screen back cover.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This device, through its thermally conductive silicone pad, heat-absorbing copper plate, heat dissipation fins, and heat dissipation holes, can absorb and conduct the heat emitted by the LCD screen, thus achieving heat dissipation for the LCD screen. Furthermore, through its exhaust fan, cooling components, semiconductor cooling chip, vents, and drying filter, it can cool the air and, through the exhaust fan's suction, achieve cooling air circulation inside the back cover of the display screen, further aiding in heat dissipation and absorption. This facilitates efficient heat dissipation for the LCD screen and ensures its safe and stable operation. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 In this utility model, a heat dissipation structure for a liquid crystal display screen includes a screen back cover 1. Two sets of heat dissipation fins 10 are fixedly embedded on the back of the screen back cover 1. The front ends of the two sets of heat dissipation fins 10 are connected to a heat-absorbing copper plate 5. A thermally conductive silicone pad 6 is connected to the front of the heat-absorbing copper plate 5. An exhaust fan 12 is fixedly embedded on the back of the screen back cover 1. A cooling component 9 is fixedly embedded on the bottom surface of the screen back cover 1. The cooling component 9 includes a cooling box 91. A semiconductor cooling chip 92 is fixedly embedded on the bottom surface of the cooling box 91. The cooling end of the semiconductor cooling chip 92 is located inside the cooling box 91. A set of vent holes 93 are opened on the front of the cooling box 91. A drying filter screen 94 is fixedly embedded on the upper surface of the cooling box 91.
[0023] The front of the display screen back cover 1 is connected to a protective gasket 2. The protective gasket 2 is made of rubber, which can increase the protection effect of the display screen back cover 1 during installation and avoid damage to the LCD screen. The front of the display screen back cover 1 has two sets of mounting holes 3. Each mounting hole 3 has a mounting screw 4 fitted on its inner wall, which can facilitate the installation of the display screen back cover 1 to the back of the LCD screen.
[0024] The back cover 1 of the display screen is connected to a handle 8 on both the left and right sides. Each handle 8 has an anti-slip sleeve 81 on its outer surface, which makes it easy to pick up the back cover 1 of the display screen and facilitates the installation of the back cover 1 of the display screen. Each heat dissipation fin 10 has a set of heat dissipation holes 11 on its outer surface. The heat dissipation holes 11 are elliptical and can increase the heat dissipation effect of the heat dissipation fin 10. The back cover 1 of the display screen has a model number 7 on its upper surface. The model number 7 is located in the middle of the back cover 1 of the display screen and can describe the model of this heat dissipation structure, which can help installers understand and use it.
[0025] The working principle of this utility model is as follows:
[0026] In use, first, lift the back cover 1 of the display screen by holding the handle 8 and align it with the rear end of the LCD screen. Then, install it onto the rear end of the LCD screen using the mounting screws 4. During use, the heat dissipated by the LCD screen is absorbed by the thermally conductive silicone pad 6 and the heat-absorbing copper plate 5 and conducted away through the heat dissipation fins 10 and heat dissipation holes 11 to dissipate heat from the LCD screen. The semiconductor cooling chip 92 in the cooling component 9 generates cooling air, and the exhaust fan 12 draws the cooled air into the back cover 1 of the display screen, achieving cooling air circulation inside the back cover 1. This assists in the dissipation and absorption of heat from the LCD screen, achieving efficient heat dissipation and ensuring the safe and stable use of the LCD screen.
