[0002] Liquid crystal display is a type of flat-panel display used for television and computer screen displays. Liquid crystal display uses a pixel-level display method and is good at displaying details, allowing users to enjoy a high-quality image experience.

[0003] Existing patent application number: CN202122274222.0 A frame structure of a liquid crystal display and its liquid crystal display, including a liquid crystal display body and an inner frame, an inner frame is provided on the outside of the liquid crystal display body, and a plurality of tightening grooves are provided on the upper and lower plate walls of the inner frame, and bidirectional screw rods are rotatably installed in the tightening grooves, one end of several of the bidirectional screw rods are fixedly connected to a cross rod, and one end of several of the cross rods are rotatably passed through the inner frame.

[0004] The above patent records a liquid crystal display screen. As user demand continues to increase, high-end liquid crystal displays have increasingly powerful performance in processing images and videos. However, the high-performance mode will also increase the operating frequency and voltage of the electronic components inside the display, thereby generating more heat. If the heat cannot be effectively dissipated, the life of these electronic components will be greatly shortened, especially for wall-mounted liquid crystal display screens. Since the screen is close to the wall, the heat cannot be dissipated quickly, which can easily reduce the service life of the screen. In addition, the heat dissipation structure of the liquid crystal display screen in the prior art is usually integrated inside the screen body, which is difficult to disassemble and clean, making the cleaning cycle of the heat dissipation structure very long, and the dust accumulated inside is difficult to be dealt with in time, thereby affecting the actual use effect of the heat dissipation structure. For this reason, we propose an efficient heat dissipation liquid crystal display screen to solve the above problems. Utility Model Content

[0028] See also Figure 6-7The utility model provides an efficient heat dissipation type liquid crystal display screen. The multifunctional heat dissipation structure 3 also includes a guide groove 310, a hook 311, a slide button 312 and a hanging groove 313. The left and right parts of the bottom surface of the assembly groove 31 are symmetrically provided with guide grooves 310. The inner side of the guide groove 310 is slidably installed with a hook 311. The longitudinal section of the hook 311 is T-shaped.

[0031] Here’s how it works:

[0032] First, assemble the assembly shell 33 and the machine box 2. The specific operation method is: first install the assembly shell 33 into the inner side of the assembly slot 31, so that the assembly shell 33 is buckled on the outside of the heat dissipation fins 32, and then move the assembly shell 33 down to the bottom surface of the assembly slot 31. During this process, the hook 311 will pass through the hanging slot 313 and extend to the inner side of the assembly shell 33. Then, the slide button 312 is used to control the hook 311 to move to the end of the guide slot 310, so that the hook 311 enters the end of the hanging slot 313. At this time, the hook 311 and the hanging slot 313 are stuck with each other and cannot be separated, so that the assembly shell 33 is installed and fixed on the inner side of the assembly slot 31. The installation can be completed without the aid of external tools. The operation is simple and quick. Finally, the control line 39 is connected to the control interface 38 to establish a control connection between the machine box 2 and the controller 37.

[0033] Second, during the operation of the LCD screen 1, the machine box 2 starts the multifunctional heat dissipation structure 3, so that the fan groups 36 on both sides of the assembly shell 33 are powered on and run. At this time, the heat dissipation slots 34 on one side of the assembly shell 33 take in air, and the heat dissipation slots 34 on the other side discharge air, thereby taking away the heat from the back of the LCD screen 1. Among them, the heat dissipation fins 32 can further increase the heat dissipation area on the back of the LCD screen 1 to enhance the heat dissipation effect. In addition, the multifunctional heat dissipation structure 3 performs air cooling in a horizontal direction, which is not easily obstructed by walls, and can effectively control the temperature of the LCD screen 1.

[0034] Third, when the multifunctional heat dissipation structure 3 needs to be disassembled and cleaned, first release the connection between the control line 39 and the control interface 38, then control the hook 311 to move to the head end of the guide groove 310 through the slide button 312, so that the hook 311 enters the head end of the hanging groove 313, and then lift the assembly shell 33 until the hook 311 is separated from the inner side of the hanging groove 313, and the assembly shell 33 can be removed from the inner side of the assembly groove 31. The disassembly can be completed without the aid of external tools. The operation is simple and quick. Finally, the dustproof net 315 can be pulled out from the inner side of the clamping groove 314 for cleaning and replacement. The cleaning operation is convenient, and the dust accumulated inside the multifunctional heat dissipation structure 3 can be processed in time to ensure the heat dissipation effect.
