Embodiment 1

[0029] See Figure 1-2 , a LED screen based on natural wind air-cooled heat dissipation technology, comprising a screen body 1, the rear side end of the screen body 1 is fixedly connected to a rear shell 2, the outer side of the rear shell 2 is provided with an air intake pipe 4, and the rear shell The middle part of the rear wall of 2 is embedded with a vent pipe 3, the vent pipe 3 is a cylindrical structure with an open front end, the open end of the vent pipe 3 is provided with a first protective net 31, and the outer circular surface of the vent pipe 3 is uniform. There are several heat exchange tubes 5 through which are connected, the heat exchange tubes 5 are arc tubes, the heat exchange tubes 5 are trumpet-shaped structures, and the large-diameter ends of the heat exchange tubes 5 are connected through the air intake pipe 4, and the air intake pipes 4 is an annular pipe, and the outer end of the air intake pipe 4 is evenly provided with a number of air intake holes 6, a...

Embodiment 2

[0032] See image 3 The difference from Embodiment 1 is: the side wall of the ventilation pipe 3 is embedded with a blast pipe 32, the axis of the ventilation pipe 3 coincides with the axis of the blast pipe 32, and the blast pipe 32 is far away from the screen body One end of 1 runs through the first protective net 21 and is equipped with a heat dissipation fan 33. The inner cavity of the blast pipe 32 is provided with a dust filter 34, a first water filter layer 35, a second water filter layer 36 and a third water filter layer. The water filter layer 37, the first water filter layer 35 is a silica gel particle layer, the second filter layer 36 is a calcium chloride particle layer, and the third filter layer 37 is an active carbon particle layer; Draw the outside air, so that the outside air enters the inner cavity of the rear shell 2 through the air blast pipe 32, and the air passes through the dust filter 34, the first water filter layer 35, the second water filter layer 36...

Embodiment 3

[0034] See Figure 4 , the difference from Embodiment 1 is that: the mounting frame 10 includes a first fixing frame 101, the first fixing frame 101 is a U-shaped structure, and the left and right side ends of the first fixing frame 101 are symmetrically provided with a second fixing frame 102, the second fixed frame 102 is an L-shaped structure, the first fixed frame 101 and the second fixed frame 102 are integrally formed, and the first fixed frame 101 is uniformly provided with a plurality of first threaded holes 103, so A first bolt 104 is installed in the first threaded hole 103, a second threaded hole 105 is provided on the second fixed frame 102, a second bolt 106 is installed in the second threaded hole 105, and the second bolt 106 Cooperating with the second threaded hole 105, the rear case 2 can be installed on the second fixed device 102, and at the same time, the first fixing bracket 101 can be installed on the wall through the first bolt 104 and the first threaded...

Abstract

The invention discloses an LED screen based on a natural wind air-cooling heat dissipation technology, which comprises a screen body, the rear side end of the screen body is fixedly connected with a rear shell; the outer side of the rear shell is sleeved with an air inlet pipe, a breather pipe is embedded in the middle of the rear wall of the rear shell, a plurality of heat exchange pipes are evenly connected to the outer circle face of the breather pipe in a penetrating mode, the large-diameter ends of the heat exchange pipes are connected to the air inlet pipe in the penetrating mode, a plurality of air inlet holes are evenly formed in the outer side end of the air inlet pipe, and a second drainage plate and a first drainage plate are arranged on the left and right sides of the outer side ends. In the whole heat dissipation process, the structure of the first drainage plate and the structure of the second drainage plate are used for guiding air flowing near the air inlet pipe; and then flowing air flows in the heat exchange pipe to take away the temperature in the inner cavity of the rear shell, so that the whole device is cooled, no other heat is generated in the whole cooling process, the flowing air completely cools the whole device, and the cooling effect of the whole device can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of LED screens, in particular to an LED screen based on natural wind cooling heat dissipation technology. Background technique [0002] The LED screen is a display method that controls semiconductor light-emitting diodes. Its general appearance is composed of many small lights that are usually red, green, and blue, and characters are displayed by turning on and off the lights. A large display screen used to display various information such as text, graphics, images, animations, market prices, videos, and video signals. [0003] The characteristics of the screen are: 1. Outdoor full-color LED large screens are widely used in public places, advertising, urban road networks, urban parking lots, railways, subways and other traffic guidance systems, highways, etc.; 2. Using VGA synchronization technology, large The content of the screen is synchronized with the CRT, and the replacement of advertising content is ...
