[0028] Please refer to Figure 1 , Figure 2 and Figure 3 , in the drawings, the units with similar structures are denoted by the same reference numerals.

[0029] The present embodiment provides a high-efficiency heat-dissipation LCD screen, which comprises a screen frame 11, a screen body 14, an air inlet fan 12, and an air outlet fan 13. One side of the screen body 14 is a display surface.

[0030] The screen frame 11 has a mounting opening. The screen body 14 is assembled into the screen frame 11 through the mounting opening. The display surface displays information to a user through the mounting opening. The screen body 14 is spaced apart from the inner wall surface of the screen frame 11 by a certain distance and forms a heat-dissipation cavity 112. The top end of the screen frame 11 away from the mounting opening is provided with an air outlet communicating with the heat-dissipation cavity 112. The bottom of the screen frame 11 is provided with an air inlet communicating with the heat-dissipation cavity 112. The air outlet fan 13 is arranged at the air outlet. The air inlet fan 12 is arranged at the air inlet. The air inlet fan 12 and the air outlet fan 13 can accelerate the flow of air in the heat-dissipation cavity 112, and the heat-dissipation efficiency of the screen body 14 is high, and the cooling effect is good.

[0031] Please refer to Figure 3 , in the present embodiment, the air inlet fan 12 comprises a fan blade assembly 123 and an air inlet shell 122. The fan blade assembly 123 is rotatably arranged in the air inlet shell 122. The air inlet shell 122 is provided with an input port 124 and an output port 125. The input port 124 and the output port 125 are located in the radial direction of the rotating shaft of the fan blade assembly 123, that is, the air inlet fan 12 is a cross-flow fan. In this way, the area of the output port 125 of the air inlet fan 12 can be set larger, and the air flow delivery of the air inlet fan 12 is large.

[0032] Please refer to Figure 1 and Figure 3 , in the present embodiment, the air inlet fan 12 is fixedly connected with the screen frame 11 through a connecting piece 15. The connecting piece 15 comprises a first connecting plate 151 and a second connecting plate 152 connected in an L-shaped structure. The first connecting plate 151 is fixedly connected with the side of the screen frame 11 away from the mounting opening. The second connecting plate 152 is connected with the air inlet fan 12.

[0033] The top and bottom of the screen frame 11 are provided with clamping plates 111 for fixed connection with the frame plate 16, and the clamping plates 111 are provided with connecting grooves 1111. It can be understood that a protruding column can be provided on the frame plate 16, and the protruding column is provided with a threaded hole. The connecting grooves 1111 are positioned and connected with the protruding column, and then a screw is used to pass through the connecting grooves 1111 and is connected with the threaded hole on the protruding column, so as to lock and fix the clamping plates 111 with the frame plate 16.

[0034] Please refer to Figure 3 Specifically, the second connecting plate 152 extends away from the mounting port, and the angle between the first connecting plate 151 and the second connecting plate 152 is between 65° and 85°. This facilitates the disassembly and assembly of the clamping plates 111 and the frame plate 16, and the airflow output by the air inlet fan 12 can be more concentrated to blow to the screen body 14, so that the heat dissipation efficiency is higher.

[0035] Please refer to Figure 1 In this embodiment, the air inlet shell 122 is provided with fixed plates 121 at both ends, and the second connecting plate 152 is provided with extension plates 153 at both ends. The two extension plates 153 are connected with the mutually faraway sides of the two fixed plates 121 one by one, and the second connecting plate 152 is located between the input port 124 and the output port 125 of the air inlet shell 122. The connecting piece 15 can stably connect the air inlet fan 12 with the screen frame 11.

[0036] The output port 125 is away from the air inlet port by a certain distance, and the length and width of the output port 125 are greater than those of the air inlet port. In this way, the air of the air inlet fan 12 can cover the space inside and outside the screen frame 11 at the same time, and the heat of the screen frame 11 can be quickly dissipated, so that the heat dissipation is more efficient.

[0037] In this embodiment, a filter screen can be arranged on the input port 124 of the air inlet fan 12 to avoid blowing too much dust into the heat dissipation cavity 112.

[0038] Optionally, a plurality of heat dissipation fins can be arranged on the inner wall surface of the screen frame 11. The extension direction of the heat dissipation fins is perpendicular to the plane of the air inlet port, that is, the extension direction of the heat dissipation fins is along Figure 3 the vertical direction in the screen frame 11, which is beneficial to the rapid flow of air through the heat dissipation cavity 112, and the plurality of heat dissipation fins can improve the heat dissipation efficiency of the screen frame 11. Generally, the airflow in the vertical central region of the heat dissipation cavity 112 is the strongest, so the density of the plurality of heat dissipation fins in the vertical central region of the inner wall surface of the screen frame 11 can be greater than that in the two side regions, so that the overall flow speed of the air in the heat dissipation cavity 112 is faster.

[0039] The screen frame 11 in this embodiment can be made of aluminum alloy, which has good strength and good heat dissipation effect.

[0040] The high-efficiency heat dissipation LCD screen of the preferred embodiment can accelerate the air flow in the heat dissipation cavity, and has high heat dissipation efficiency and good cooling effect.

[0041] Meanwhile, the output port of the air inlet fan has a length and width greater than that of the air inlet port, and the output port is spaced apart from the air inlet port by a set distance.

[0042] In summary, although the preferred embodiment has been disclosed as above, the preferred embodiment is not intended to limit the present application, and those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present application. Therefore, the protection scope of the present application is defined by the scope of the claims.
