Referring to FIGS. 1 to 7 , this embodiment provides a thin outdoor advertising machine, including:

A cabinet 1, wherein a back panel 110 of the cabinet 1 is provided with an air inlet 111, and an end away from the air inlet 111 is provided with an air outlet 112; an effective display area of a front panel 120 of the cabinet 1 is provided with a transparent protective layer 2;

A display module 3, the display module 3 is arranged in the inner cavity of the cabinet 1; the display module 3 includes a liquid crystal assembly 310 and a backlight assembly 320; the liquid crystal assembly 310 is arranged corresponding to the effective display area, and a first air duct interval 4 is provided between the liquid crystal assembly 310 and the transparent protective layer 2;

An electrical module 5, the electrical module 5 is disposed in the inner cavity of the cabinet 1, and the electrical module 5 is electrically connected to the display module 3;

A partition support middle plate 6, the partition support middle plate 6 is provided between the display module 3 and the electrical module 5; the backlight assembly 320 is connected to the partition support middle plate 6; a second air duct interval 7 is provided between the electrical module 5 and the partition support middle plate 6;

An air inlet fan group 8, the side wall of which is connected to the inner wall of the cabinet 1, and the air inlet fan group 8 is arranged at one end of the partition support middle plate 6; the air inlet end 810 of the air inlet fan group 8 is connected to the air inlet 111, and the air outlet end 820 of the air inlet fan group 8 is connected to the first air duct interval 4 and the second air duct interval 7;

An exhaust fan group 9, wherein the side wall of the exhaust fan group 9 is connected to the inner wall of the cabinet 1, and the exhaust fan group 9 is arranged at the other end of the partition support middle plate 6; the air inlet end 910 of the exhaust fan group 9 is connected to the first air duct interval 4 and the second air duct interval 7; the air outlet end 920 of the exhaust fan group 9 is connected to the air outlet 112.

When the thin outdoor advertising machine is working, the air inlet fan group 8 fans to draw the outside air from the air inlet 111 and the air inlet end 810 into the first air duct interval 4 and the second air duct interval 7; the exhaust fan group 9 also works synchronously, and its function is to draw the air in the first air duct interval 4 and the second air duct interval 7 from the air inlet end 910 and the air outlet end 920 to the air outlet 112 and the outside.

Since the backlight assembly 320, which generates relatively large amounts of heat during operation, is connected to the partition support middle plate 6, the partition support middle plate 6 acts as a heat sink for the backlight assembly 320, and one end surface of the partition support middle plate 6 is located in the second air duct interval 7, the air flow generated by the air inlet fan group 8 and the exhaust fan group 9 can take away the heat in the second air duct interval 7 when passing through the second air duct interval 7, thereby cooling the backlight assembly 320. The second air duct interval 7 is also enclosed by the electrical module 5, and the heat generated by the components in the electrical module 5 during operation will also be dissipated into the second air duct interval 7 and taken away for heat dissipation.

In the prior art, the LCD screen in the LCD assembly 310 is a black liquid crystal component. There is strong solar radiation outdoors, and the black color absorbs a lot of heat. The temperature of the LCD assembly 310 is too high, and a black screen phenomenon will occur. However, the present application forms an air duct by providing a first air duct interval 4 between the liquid crystal assembly 310 and the transparent protective layer 2, and the air inlet fan group 8 and the exhaust fan group 9 work at the same time. Thanks to the air outlet end 820 of the air inlet fan group 8 connecting to the first air duct interval 4 and the second air duct interval 7, and the air inlet end 910 of the exhaust fan group 9 connecting to the first air duct interval 4 and the second air duct interval 7, the air flow in the first air duct interval 4 is also driven by the air inlet fan group 8 and the exhaust fan group 9. Therefore, the outdoor advertising machine does not need to set up an additional cooling fan group and can be designed to be lighter and thinner.

Among them, this outdoor advertising machine can be designed to avoid being heavy and is thinner than outdoor advertising machines in the same field because the air inlet fan group 8 and the exhaust fan group 9 are respectively arranged at the two ends of the partition support middle plate 6, and the side walls of the air inlet fan group 8 are connected to the inner wall of the cabinet 1, and the side walls of the exhaust fan group 9 are connected to the inner wall of the cabinet 1, which avoids the traditional outdoor advertising machine using a large-area fan blade type cooling fan, and the fan is tilted. Only the air volume is considered, but the air duct structure is not optimized. This outdoor advertising machine optimizes the connection and placement relationship between the air inlet fan group 8, the exhaust fan group 9 and the cabinet 1. The side walls of the air inlet fan group 8 and the exhaust fan group 9 are connected to the inner wall of the cabinet 1, which play the role of forming the first air duct interval 4 and the second air duct interval 7. The front and rear ports of the air duct are directly provided with cooling fans, which can ensure the stability of wind pressure and avoid heat storage in the air duct. Therefore, there is no need to use a cooling fan with large fan blades. This outdoor advertising machine can be made thinner to avoid a heavy and bulky visual effect, avoid occupying a large area and affecting the aesthetics of the advertising machine, and avoid inconvenience in installation, maintenance, and transportation.

The heat dissipation structure of the outdoor advertising machine is optimized to prevent the electrical module 5 and the backlight assembly 320 from overheating during operation, thereby reducing the failure rate and extending the service life.

In some embodiments, the transparent protective layer 2 is ultra-white tempered glass.

1 , 2 and 6 , a heat insulating spacer 315 is provided between the liquid crystal assembly 310 and the backlight assembly 320 ; the liquid crystal assembly 310 and the backlight assembly 320 are connected via a connection box 330 and enclose the side edges.

By providing the heat insulation spacer 315, the distance between the liquid crystal assembly 310 and the backlight assembly 320 is increased, so that the liquid crystal assembly 310 is less affected by the backlight assembly 320. At the same time, in order to prevent the brightness of the liquid crystal assembly 310 from being reduced when the backlight assembly 320 irradiates the liquid crystal assembly 310, a connection box 330 is provided to connect and enclose the sides of the two, so as to prevent light from leaking to the outside and being unfocused, thereby affecting the display of the liquid crystal assembly 310.

Referring to FIG. 6 , the backlight assembly 320 is a plurality of strip-shaped light panels, and a separation space 321 is provided between each of the plurality of strip-shaped light panels.

By designing the backlight assembly 320 to have a separation space 321, a plurality of strip-shaped light boards are provided with a separation space 321 between each other, thereby avoiding the conventional backlight circuit board using a whole board body and having poor heat dissipation performance.

Preferably, the cooling fan in the exhaust fan group 9 is a blower fan; the cooling fan in the inlet fan group 8 is a DC fan; and the axis of the cooling fan shafts in the inlet fan group 8 and the exhaust fan group 9 are parallel to the length direction of the partition support middle plate 6; the outlet end 920 of the blower fan is directly connected to the air outlet 112.

The cooling fan shaft axes of the air inlet fan group 8 and the exhaust fan group 9 are parallel to the length direction of the partition support middle plate 6, so as to avoid the air inlet fan group 8 and the exhaust fan group 9 being tilted. Such a structure can well constitute the first air duct interval 4 and the second air duct interval 7.

Please refer to FIG. 2 and FIG. 4 , an air inlet cover 10 is provided between the air inlet fan group 8 and the air inlet port 111 , and the air inlet end 810 of the air inlet fan group 8 is connected with the air inlet port 111 through the air inlet cover 10 ; a filter screen 1010 is provided in the air inlet cover 10 .

The filter 1010 reduces the amount of debris and dust from the outside air that enters the inner cavity of the cabinet 1 through the air inlet 111 and the air inlet fan assembly 8.

Preferably, the side plate 130 of the cabinet 1 is a profile plate.

By designing the side plate 130 as a profile plate, the structural strength of the cabinet 1 is enhanced and the cabinet 1 is prevented from being too thick and heavy.

Please refer to Figures 4 and 6. The electrical module 5 includes a supporting frame 510, a mounting plate 520, and a power supply 530, a constant current plate 540, a temperature control plate 550, a main control plate 560, a fan adapter plate (not shown), and a display screen driver plate (not shown) installed on the mounting plate 520; the power supply 530, the constant current plate 540, the temperature control plate 550, the main control plate 560, the fan adapter plate (not shown), and the display screen driver plate (not shown) are arranged between the mounting plate 520 and the partition support middle plate 6, and are located in the second air duct interval 7.

Referring to FIG. 4 , a heater 11 is provided adjacent to the air inlet end 810 of the air inlet fan assembly 8 , and the heater 11 is electrically connected to the electrical module 5 .

When the outdoor advertising machine is used in some cold environments, the heater 11 generates heat, the air entering the air inlet 111 is heated, and then flows into the first air duct interval 4 and the second air duct interval 7. The electronic components in contact with the first air duct interval 4 and the second air duct interval 7 can also be heated to ensure normal operation.

Please refer to FIG. 7 , the air outlet end 820 of the air inlet fan group 8 and the air inlet end 910 of the air exhaust fan group 9 are both provided with an air duct guide plate 850 connected to the first air duct interval 4 and the second air duct interval 7 .

The air duct guide plate 850 is connected to the partition support middle plate 6 to separate the wind force generated by the air inlet fan group 8 and the air exhaust fan group 9 and connect them to the first air duct interval 4 and the second air duct interval 7 respectively.

The air duct guide plate 850 separates the first air duct interval 4 and the second air duct interval 7 to prevent strong solar radiation outdoors, which may cause the temperature of the first air duct interval 4 at the location of the liquid crystal assembly 310 to rise and the heat to diffuse to the second air duct interval 7.

Please refer to FIG. 2 and FIG. 4 , which includes a lightning arrester 12 electrically connected to the electrical module 5 .
