Description

Technical Field

[0001] This utility model relates to the field of advertising machine technology, and more specifically, to an outdoor advertising machine with heat dissipation function. Background Technology

[0002] In existing technologies, outdoor advertising displays typically consist of a housing, an LCD screen, an electronic control box, and a heat dissipation mechanism. The heat dissipation mechanism usually comprises a front-facing fan, an air inlet fan, and an exhaust fan. The front-facing fan dissipates heat from the LCD screen, while the exhaust fan expels heat from the entire unit to the external environment. Air from the external environment enters the unit through the air inlet, thus achieving internal and external air circulation for heat dissipation. This heat dissipation structure relies primarily on convection cooling from the external air, which provides some cooling effect. However, it has significant limitations in high-temperature environments. This is mainly because the external air temperature is also relatively high, making it difficult to effectively remove heat from the unit after entering, thus failing to achieve ideal heat dissipation. This can easily affect the normal operation of critical components such as the LCD screen and the electronic control box, thereby reducing the lifespan of the outdoor advertising display.

Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This utility model embodiment provides an outdoor advertising machine with heat dissipation function, such as... Figure 1 and Figure 2 As shown, the outdoor advertising machine with heat dissipation function includes a housing 1, inside which is a liquid crystal screen 2, an electronic control box 3, and a cooling component. A first heat dissipation channel 10 is provided between the screen surface of the liquid crystal screen 2 and the front panel 11 of the housing 1; a second heat dissipation channel 20 is provided between the back of the liquid crystal screen 2 and the electronic control box 3; and a third heat dissipation channel 30 is provided between the electronic control box 3 and the rear door panel 13 of the housing 1. The housing 1 is also provided with an air inlet 101 and an air outlet 102, both of which communicate with the first heat dissipation channel 10, the second heat dissipation channel 20, and the third heat dissipation channel 30. The cooling component is located at the air inlet 101 and includes an air compressor 4, a vortex tube 5, and an intake fan 6. The air outlet channel of the air compressor 4 communicates with the air inlet channel of the vortex tube 5. The intake fan 6 corresponds to the air outlet channel of the vortex tube 5 to deliver the cool air from the vortex tube 5 into the first heat dissipation channel 10, the second heat dissipation channel 20, and the third heat dissipation channel 30.

[0022] In this embodiment of the outdoor advertising machine with heat dissipation function, the air compressor 4 uses air as a refrigerant. This method has significant environmental advantages, as it eliminates the need for special chemical refrigerants and air is widely available. The air compressor 4 compresses the air to 5.5-6.9 bar, and the compressed air enters the vortex rotation chamber of the vortex tube 5 at high speed tangentially, thus forming a free vortex. In the free vortex, friction occurs between layers as the rotational angular velocity gradually decreases from the center to the outer layers. The airflow velocity is fastest in the central part, transferring energy to the lower-velocity airflow in the outer layers through friction. During this process, the airflow in the central layer loses energy, its kinetic energy decreases, and its speed and temperature also decrease. Finally, the cold airflow is drawn out from the outlet channel of the vortex tube 5 through the central perforated plate, and then sent into the first heat dissipation channel 10, the second heat dissipation channel 20, and the third heat dissipation channel 30 by the intake fan 6, thereby achieving heat dissipation of the interior of the housing 1 (including the LCD screen 2 and the electronic control box 3).

[0023] Specifically, in this embodiment, the housing 1 is composed of a front panel 11, a main frame 12, and a rear door panel 13. The front panel 11 is located on the front side of the main frame 12, and the rear door panel 13 is located on the rear side of the main frame 12, forming an internally sealed housing 1. The LCD screen 2 typically consists of an LCD screen back panel and an LCD screen body. The LCD screen back panel is used to fix and install on the front side of the main frame 12, and the LCD screen body is attached to the LCD screen back panel and faces the front panel 11. There is a first gap between the LCD screen body and the front panel 11. The portion of the front panel 11 corresponding to the LCD screen body should be designed to be visible, for example, made of transparent material to display the screen surface of the LCD screen 2.

[0024] The interior of the housing 1 is cooled by an air inlet 101, an air outlet 102, a first heat dissipation channel 10, a second heat dissipation channel 20, a third heat dissipation channel 30, and an air-cooling component. The electrical control box 3 is mounted on the main frame 12, and a second gap exists between the electrical control box 3 and the rear door panel 13. In this embodiment, the first heat dissipation channel 10, the second heat dissipation channel 20, and the third heat dissipation channel are interconnected, allowing cool air to be adequately delivered to different areas within the housing 1.

[0025] Specifically, in this embodiment, the main frame 12 includes a left side plate 121, a right side plate 122, an upper side plate 123, and a lower side plate 124 that form a rectangular frame, and the electrical control box 3 is disposed within the rectangular frame. The main frame 12 also includes a first crossbar 125, a second crossbar 126, and a third crossbar 127, which are sequentially and intermittently distributed from top to bottom between the left side plate 121 and the right side plate 122. The upper end of the electrical control box 3 is detachably connected to the first crossbar 125, and the lower end of the electrical control box 3 is detachably connected to the second crossbar 126, facilitating the assembly and disassembly of the electrical control box 3 and thus improving the convenience and efficiency of maintaining the electrical control box 3.

[0026] For example, the upper end of the electrical control box 3 is provided with a first mounting bracket 31. The first mounting bracket 31 is fastened to the first crossbar 125 by a first fastener (not shown in the figure). The first mounting bracket 31 is provided with a first mounting hole, and the first crossbar 125 is provided with a first threaded hole. The first fastener (not shown in the figure) is, for example, a first screw, so that the first screw is inserted into the first mounting hole and threadedly fastened into the first threaded hole, thereby realizing the detachable connection between the first mounting bracket 31 and the first crossbar 125. A second mounting bracket 32 ​​is provided at the lower position of each of the two opposite side walls of the electrical control box 3. Each second mounting bracket 32 ​​is fastened to the second crossbar 126 by a second fastener (not shown in the figure). Each second mounting bracket 32 ​​is provided with a second mounting hole, and the second crossbar 126 is provided with several corresponding second threaded holes. The second fastener is, for example, a second screw, so that the second screw is inserted into the second mounting hole and threadedly fastened into the second threaded hole, thereby realizing the detachable connection between the second mounting bracket 32 ​​and the second crossbar 126.

[0027] Specifically, in this embodiment, both the air inlet 101 and the air outlet 102 are located on the rear door panel 13. The air outlet 102 is located at the upper part of the rear door panel 13, and the air inlet 101 is located at the lower part of the rear door panel 13. The air-cooling assembly also includes an exhaust fan 7 located at the air outlet 102, which can effectively promote gas circulation and exchange inside the housing 1. A mounting plate 128 is provided on the side of the third crossbar 127 near the rear door panel 13, and the mounting plate 128 is perpendicular to the third crossbar 127. The air compressor 4 and the vortex tube 5 are both located below the mounting plate 128. The intake fan 6 is located on the mounting plate 128, and the intake end of the intake fan 6 faces downwards, opposite to the exhaust channel of the vortex tube 5, so as to convey the cold air in the vortex tube 5 upwards to be sent into the first heat dissipation channel 10, the second heat dissipation channel 20, and the third heat dissipation channel 30. Air compressor 4 compresses air and inputs it into vortex tube 5 for cooling. The resulting cold air, under the action of intake fan 6, enters the first heat dissipation channel 10, the second heat dissipation channel 20, and the third heat dissipation channel 30 respectively. The cold air flows in the first heat dissipation channel 10, the second heat dissipation channel 20, and the third heat dissipation channel 30, absorbing the heat generated by various components, thereby achieving heat dissipation for key components such as LCD screen 2 and electronic control box 3. Finally, the hot air inside the housing 1 is discharged into the external environment through air outlet 102.

[0028] From an overall structural layout perspective, the components of the outdoor advertising machine with heat dissipation function in this embodiment of the invention are closely coordinated. The air compressor 4 provides compressed air as the power source for cooling; the vortex tube 5 realizes the cooling process; the intake fan 6 is responsible for sending cool air into the first heat dissipation channel 10, the second heat dissipation channel 20, and the third heat dissipation channel 30; the LCD screen 2 and the electronic control box 3, as the core functional components of the outdoor advertising machine, can operate stably in this good heat dissipation environment; the housing 1 not only protects the internal components but also participates in forming the heat dissipation channels, enhancing the heat dissipation effect. The outdoor advertising machine with heat dissipation function in this embodiment of the invention can achieve effective heat dissipation in high-temperature environments, greatly expanding the application scenarios of the outdoor advertising machine, extending its overall service life, and significantly reducing maintenance costs.

[0029] In this embodiment, the air compressor 4 is, for example, a silent air compressor, to reduce noise during heat dissipation. It should be noted that the structures of the air compressor 4 and the vortex tube 5 used in this embodiment are relatively existing. In practical applications, any suitable air compressor 4 and vortex tube 5 from the prior art can be selected; this embodiment does not impose any specific limitations. The relevant electrical control components installed in the electrical control box 3 can be designed and selected according to actual application needs; this embodiment also does not impose any specific limitations.
