[0032] See Figures 1 to 7 This utility model discloses an outdoor advertising machine with excellent heat dissipation, which can be used for outdoor advertising playback and / or outdoor advertising display.

[0033] In some embodiments, the outdoor advertising machine with good heat dissipation includes a cabinet 10, which includes a cabinet body 11 and an upper cabinet door 12 and a lower cabinet door 13 that cooperate with the cabinet body 11; the front panel 111 of the cabinet body 11 is provided with a display window, the display window is provided with a glass plate 20, the cabinet body 11 is provided with a display device 30, the display device 30 is disposed opposite to the glass plate 20, the gap between the display device 30 and the glass plate 20 forms a front heat dissipation channel A, and the gap between the display device 30 and the upper cabinet door 12 forms a rear heat dissipation channel B;

[0034] The lower cabinet door 13 is provided with an air inlet 131, and the upper cabinet door 12 is provided with an air outlet 121, which may be located at the upper part of the upper cabinet door 12. A mounting plate 14 is provided inside the cabinet body 11, located below the display device 30. A first air guide 15 is provided on the mounting plate 14, with its upper end extending near the glass plate 20. A second air guide 16 is also provided inside the cabinet body 11, located above the display device 30. The second air guide 16 has a downwardly curved arc structure, and the space below the second air guide 16 connects the front heat dissipation channel A and the rear heat dissipation channel B.

[0035] The mounting plate 14 is equipped with a plurality of centrifugal fans 40, at least some of the centrifugal fans 40 having their air outlets facing the front heat dissipation channel A of the screen, and at least some of the centrifugal fans 40 having their air outlets facing the rear heat dissipation channel B of the screen.

[0036] When the outdoor advertising machine with excellent heat dissipation is cooling down, a portion of the airflow blown by the centrifugal fan 40 is guided by the first guide element 15 and enters the front heat dissipation channel A. The airflow flows upward, carrying away the heat in front of the display device 30. When the airflow reaches the top of the display device 30, it is guided by the second guide element 16 into the rear heat dissipation channel B, carrying away the heat behind the screen, and then exiting from the air outlet 121. Due to the presence of the second guide element 16, the airflow is smoother, preventing the airflow from lingering above the display device 30 and affecting the heat dissipation and cooling effect of the display device. In addition, a portion of the airflow blown by the centrifugal fan 40 directly enters the rear heat dissipation channel B, carrying away the heat behind the screen, and then exiting from the air outlet 121, improving the heat dissipation effect.

[0037] This outdoor advertising machine has excellent heat dissipation, which can effectively prevent high temperatures from affecting the normal operation of the display device 30, thus effectively improving the overall service life of the outdoor advertising machine and reducing maintenance costs.
