The advertising screen of the present application can independently and integrally dissipate the heat of the driving module 4 and the functional module 5 of the display board, greatly improving the heat dissipation effect and extending the service life of the advertising screen.

[0026] Next, the advertising screen with good heat dissipation effect in this exemplary embodiment will be further described.

[0027] In the embodiment of the present application, the back cover 2 is detachably connected to the rear end face of the outer frame 1. Specifically, it can be connected by bolts or by snap-on connection, so that the back cover 2 is easy to disassemble and assemble. When maintenance is required, the back cover 2 can be quickly disassembled to inspect the internal advertising screen body without disassembling the entire advertising screen body. The operation is convenient and quick. The advertising screen body includes a display panel, a display mounting plate 3, a drive module 4 and a functional module 5. The display panel is installed on one side of the display mounting plate 3. The display panel is used for advertising display. The drive module 4 and the functional module 5 are installed on the other side of the display mounting plate 3, wherein the display panel faces the outer frame 1 away from the back cover 2. The drive module 4 is used to drive the display panel for display, such as a control main board, a power module, etc. The drive module 4 continues to work and generates heat. The functional module 5 is used to increase the versatility of the advertising screen, such as a communication module that enables it to have a communication function. By dividing the electronic module into the drive module 4 and the functional module 5 and installing them on the display mounting plate 3 respectively, the heat dissipation will not affect each other. A plurality of cooling fans 6 are evenly distributed on the side of the display mounting plate 3 facing the back cover 2, and a plurality of cooling holes 21 corresponding to the cooling fans 6 are provided on the back cover 2. The cooling fans 6 evenly distributed on the display mounting plate 3 can evenly dissipate the heat of the display mounting plate 3, and the cooling of the driving module 4, the functional module 5 and the display panel can be performed at the same time; at least two cooling channels 31 are provided on the side of the display mounting plate 3 facing the back cover 2, one of the cooling channels 31 connects the driving module 4 with the bottom of the outer frame 1, and the other cooling channel 31 connects the driving module 4 with a side wall of the outer frame 1. By arranging two cooling channels 31 on the display mounting plate 3 leading to the driving module 4, the driving module 4 can be further cooled separately, and the devices that generate more heat can be cooled in a targeted manner, thereby improving the overall cooling effect. At least two cooling channels 31 are arranged to form air convection, which can accelerate heat dissipation.

[0028] As an example, a mounting groove 32 is provided on one side of the display mounting plate 3 facing the rear cover 2, the driving module 4 is located at the upper part of the mounting groove 32, and a heat dissipation space 33 is formed at the lower part of the mounting groove 32. The two heat dissipation channels 31 are respectively connected to the two sides of the heat dissipation space 33. External cold air circulates in the heat dissipation space 33 through the two heat dissipation channels 31, thereby effectively dissipating the heat of the driving module 4 located in the mounting groove 32. By arranging the driving module 4 in the mounting groove 32, an annular protective structure is formed for the driving module 4, and the heat dissipation channel 31 is directly connected to the mounting groove 32, so that cold air can directly enter the mounting groove 32 to dissipate the heat of the driving module 4. The above structural design can greatly improve the heat dissipation effect of the driving module 4.

[0029] As an example, the rear cover 2 is provided with an inspection window 22 corresponding to the installation slot 32, and the inspection window 22 is provided with a first sealing cover 23 and a second sealing cover 24, wherein the first sealing cover 23 covers the driving module 4, the second sealing cover 24 is closely attached to the lower part of the first sealing cover 23, and the second sealing cover 24 is buckled and connected with the installation slot 32. Among them, the control end of the driving module 4 is located at the junction of the first sealing cover 23 and the second sealing cover 24, and by providing independent first sealing cover 23 and second sealing cover 24, the second sealing cover 24 can be directly opened to operate and control the driving module 4, while the first sealing cover 23 protects the driving module 4. Through the above structural design, the operation of the display panel is more convenient and quick.

[0030] As an example, the first sealing cover 23 is provided with a plurality of heat dissipation through holes 231 to further improve the heat dissipation effect of the driving module 4 .

[0031] As an example, a dustproof plate 34 is provided at one end of the heat dissipation channel 31 located at the outer frame 1, and the dustproof plate 34 is provided with a plurality of small holes and heat dissipation slits. The dustproof plate 34 is used to prevent a large amount of external dust from entering the interior through the heat dissipation channel 31.

[0032] As an example, the dustproof plate 34 is embedded in the outer frame 1, and the dustproof plate 34 is recessed inwardly into the end surface of the outer frame 1. By embedding the dustproof plate 34 in the inner wall of the outer frame 1, the outer frame 1 provides a certain degree of protection for the dustproof plate 34, and it is not easy for water or impurities to enter.

[0033] As an example, a side wall of at least one of the heat dissipation channels 31 is provided with a notch 311, and the notch 311 is connected to one side of the display mounting board 3. Part of the air can enter the side of the display mounting board 3 from the notch 311. When the cold air is passed in, it can assist the display mounting board 3 in cooling and dissipating heat, thereby improving the heat dissipation effect.
