The upper connection cover, the lower connection cover, the left side wall, the right side wall, the outer door structure 3 and the explosion-proof plate 4 together constitute a rectangular display screen heat dissipation shell with an internal chamber. The display screen heat dissipation shell of this embodiment is made of aluminum alloy (except the explosion-proof plate 4) to improve the heat dissipation effect. The structure is simple and compact, with good sealing, and can effectively protect the internal LED display screen. At the same time, the explosion-proof plate 4 cooperates with other structures to make it have good explosion-proof performance and safer to use. It is suitable for special occasions such as oil depots and gas stations, and broadens the use scenarios and application scope of the display screen.

[0030] In this embodiment, the heat dissipation housing of the display screen is not provided with a heat dissipation fan, and therefore is not provided with a heat dissipation hole, and is a fully sealed structure. The fully sealed structure can prevent the external environment from being affected by the explosion, such as sparks flying, etc., and broadens the application scenarios of this embodiment, especially suitable for gas stations, oil depots and other occasions. Even if the display screen fails, the stability of the external environment can be guaranteed.

[0031] In this embodiment, the outer side of the side wall 2 is provided with a heat dissipation fin 21, the inner side of the side wall 2 is provided with a mounting position for mounting the power supply 12, the power supply 12 is mounted on the mounting position on the inner side of the side wall 2, and the controller is mounted on the display screen module 5. Specifically, the side wall 2 is a heat dissipation fin plate, the outer surface of which is provided with a plurality of fins arranged at intervals, and the inner surface is used to fix and install the power supply 12, so that the heat generated by the working process of the power supply 12 can be quickly discharged through the heat dissipation fins 21, which greatly improves the heat dissipation capacity of the heat dissipation housing of the display screen, and reduces the thickness of the display screen.

[0032] In this embodiment, a heat dissipation cavity 15 is further provided in the display screen heat dissipation housing, and the heat dissipation cavity 15 is connected with the display screen module 5 installed in the display screen heat dissipation housing and the housing wall provided with the heat dissipation fins 21. After the display screen module 5 is installed in the display screen heat dissipation housing, the display screen module 5, the inner door structure 8 and the two side walls 2 form a heat dissipation cavity 15, and the heat dissipation cavity 15 structure can cooperate with the heat dissipation fins 21 to better dissipate heat and improve the heat dissipation effect.

[0033] See also Figure 4 and Figure 5 In this embodiment, the display screen heat dissipation housing further includes a support frame 7, which is disposed in the heat dissipation cavity 15 and is disposed parallel to the side wall 2.

[0035] In this embodiment, the display screen heat dissipation housing further includes a frame 13 for mounting the display screen module 5, and a heat conducting plate 16 is disposed on the frame 13. The arrangement of the heat conducting plate 16 corresponds to the arrangement of the chips of the display screen module 5.

It can also transfer the heat released by the display screen module 5 and the controller to the middle of the cavity through heat conduction, so that the heat can be dissipated through the heat dissipation fins 21, further improving the heat dissipation effect.

[0037] In this embodiment, both ends of the support frame 7 are provided with a connecting plate 71, the connecting plate 71 is arranged perpendicular to the main body of the support frame 7, and the two connecting plates 71 are arranged on different sides of the support frame 7.

This structure can increase the contact area between the support frame 7 and the frame 13, which is not only convenient for heat dissipation, but also can reduce impact and is beneficial to protecting the display screen module 5.

[0038] In this embodiment, a crossbeam 9 is fixedly provided on the end connection cover 1, and a hanging ear 10 is fixedly connected to the crossbeam 9, and the hanging ear 10 is arranged on one side of the outer door structure 3.
