Inside the heat dissipation box, a cooling fan, a mounting frame, and a semiconductor cooling chip are connected by a bracket. A heat dissipation vent is provided at the end of the heat dissipation box away from the main body of the display screen, and a dustproof mesh is provided inside the heat dissipation vent.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0022] Combination Figure 1 Figure 4 As shown, this embodiment provides a display screen with a heat dissipation structure, including a frame 10 and a display screen body 11 disposed on the frame 10. A heat dissipation structure 20 is provided on the back of the display screen body 11. The display screen body 11 is an existing device, and its specific model and working principle will not be described here. Before use, the electrical terminals of the electrical device are electrically connected to the electrical terminals of the power supply and the controller through wires.
[0023] In this embodiment, the heat dissipation structure 20 includes a heat dissipation box 201 connected to the display screen body 11. A cooling fan 205, a mounting frame 206, and a thermoelectric cooler 207 are connected to the heat dissipation box 201 via a bracket. A heat dissipation vent 202 is provided at the end of the heat dissipation box 201 away from the display screen body 11, and a dustproof mesh 203 is provided inside the heat dissipation vent 202. A disassembly / removal component 30 is provided between the heat dissipation box 201 and the dustproof mesh 203. The thermoelectric cooler 207 is an existing component, based on the Peltier effect, using direct current to drive the semiconductor material to achieve directional heat transfer, thereby absorbing heat on one side (cooling end) and releasing heat on the other side (heating end). The heat dissipation box 201 is connected to the display screen body 10. When the cooling fan 205 operates, it generates suction to ignite the thermoelectric cooler. The cold air generated by the cooling end of the cooling plate 207 is delivered to the heat-generating element inside the display body 11, thereby achieving heat dissipation of the display body 11. The disassembly and assembly component 30 includes two sets of ear plates 306 connected to the dustproof mesh 203. Each set of ear plates 306 has a rectangular hole 305, and a rectangular insert 304 is provided on the rectangular hole 305. The ear plates 306 are fixedly connected to the dustproof mesh 203, which plays a dustproof role and prevents dust from entering the heat sink box 201 when it is not dissipating heat. The rectangular insert 304 of the disassembly and assembly component 30 can be located on one side of the ear plate 306 through the rectangular hole 305 or close to the fixing plate 301 through the rectangular hole 305, which realizes the quick disassembly and assembly of the dustproof mesh 203 and the heat sink 202, and facilitates the disassembly and cleaning of the dustproof mesh 203.
[0024] Furthermore, the heat dissipation structure 20 of this embodiment also includes multiple sets of air inlet pipes 204 fixedly connected to the heat dissipation box 201. Each set of air inlet pipes 204 has a dustproof plate on its inner wall and each set of air inlet pipes 204 is connected to the cooling fan 205. The air inlet pipes 204 are used to intake air, and the cooling fan 205 delivers the air from the air inlet pipes 204 to the interior of the heat dissipation box 201.
[0025] In this embodiment, the cooling fan 205 faces the cooling end of the thermoelectric cooler 207, and a heat-conducting plate 208 is attached to the heating end of the thermoelectric cooler 207. Multiple sets of heat dissipation fins 209 and heat dissipation copper pipes 210 are installed on the side of the heat-conducting plate 208 facing the heat dissipation port 202. A heat exhaust fan 211 is mounted on the inner wall of the heat sink 201 via a bracket. The exhaust end of the heat exhaust fan 211 faces the heat dissipation port 202, and a brush 212 is installed on the shaft of the heat exhaust fan 211. The heat-conducting plate 208 has good thermal conductivity and can conduct the heat generated by the heating end of the thermoelectric cooler 207 to the heat dissipation fins. 209. Inside the heat dissipation copper pipe 210, the heat dissipation fan 211 generates suction after operation, which exhausts heat through the heat dissipation port 202, realizing rapid heat dissipation of the semiconductor cooling chip 207, ensuring the effect of the semiconductor cooling chip 207 in generating cool air, and improving the heat dissipation effect of the display screen. In the process of rotation, the heat dissipation fan 211 can drive the brush 212 to rotate on the inner side of the dustproof mesh 203, which can clean the impurities in the filter holes of the dustproof mesh 203. Combined with the air blown by the operation of the heat dissipation fan 211, the impurities in the filter holes of the dustproof mesh 203 can be cleaned out, realizing the cleaning of the inside of the dustproof mesh 203.
[0026] Furthermore, the disassembly and assembly component 30 in this embodiment also includes a fixing plate 301 fixedly connected to the heat sink 201. A pull rod 302 is rotatably inserted into the fixing plate 301, and one end of the pull rod 302 near the dustproof mesh 203 is fixedly connected to the rectangular insert 304. The pull rod 302 can be pulled and rotated, thereby driving the rectangular insert 304 to rotate and move. A spring 303 is sleeved on the outer wall of the pull rod 302, and the spring 303 is located between the fixing plate 301 and the rectangular insert 304. The elasticity of the spring 303 can always keep the rectangular insert 304... When the dust filter 203 is installed in the heat dissipation vent 202, the rectangular insert 304 moves towards one end of the fixing plate 301. Then, the pull rod 302 is rotated through the rectangular hole 305 to make it position on one side of the ear plate 306. At this time, the rectangular insert 304 no longer passes through the rectangular hole 305. When the dust filter 203 is removed, the rectangular insert 304 is rotated to pass through the rectangular hole 305. The elastic force of the spring 303 drives the rectangular insert 304 to pass through the rectangular hole 305 and move closer to the fixing plate 301. The dust filter 203 can be removed after it is no longer restricted.
[0027] In actual use, the heat dissipation box 201 of the heat dissipation structure 20 is installed on the back of the display body 11. The electrical terminals of each electrical device are connected to the electrical terminals of the power supply and controller via wires. The cooling fan 205 of the heat dissipation structure 20 generates suction, and the air inlet pipe 204 delivers air into the heat dissipation box 201, delivering the cold air generated on the thermoelectric cooler 207 into the interior of the display body 11, thus achieving heat dissipation for the heat-generating components inside the display. The heat-conducting plate 208 has good thermal conductivity, which can conduct the heat generated by the heat-generating end of the thermoelectric cooler 207 to the heat dissipation fins 209 and the heat dissipation copper pipe 210. After the exhaust fan 211 operates, the heat is discharged through the heat dissipation port 202, thus achieving heat dissipation for the thermoelectric cooler 207. Rapid heat dissipation ensures the cooling effect of the thermoelectric cooler 207, improving the heat dissipation of the display screen. During the rotation of the heat dissipation fan 211, the brush 212 can rotate on the inner side of the dust filter 203 to clean the impurities on the dust filter 203. The airflow generated by the heat dissipation fan 211 can also remove the impurities from the dust filter 203. When the dust filter 203 is disassembled, the rectangular insert 304 on the disassembly and assembly component 30 rotates to pass through the rectangular hole 305 opened on the ear plate 306. The elastic force of the spring 303 drives the rectangular insert 304 through the rectangular hole 305 and moves it closer to the fixing plate 301. Once the dust filter 203 is no longer restricted, it can be removed to avoid the dust filter 203 from being blocked and affecting the heat dissipation effect of the heating end of the thermoelectric cooler 207.
[0028] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
