[0025] Further, such as Figure 1-5 As shown, the other end of the pipe joint 110 is fixedly sleeved on the rear end of the cooling copper tube 104, and a plurality of first air inlets 111 are opened on the rear side of the heat dissipation device 107. A part of the wind can be drawn out through the air outlet duct 109, and the wind is transported to the inside of the cooling copper tube 104 through the pipe joint 110. The heat of the backlight module 102 is then absorbed by the cooling copper tube 104 in the placement groove 103, so that when the wind circulates inside the cooling copper tube 104, the heat inside the cooling copper tube 104 is driven.

[0026] Further, such as Figure 1-5As shown, the other end of the cooling copper tube 104 is movably embedded in the right side of the shell 1, and slide grooves 2 are opened at both ends of the rear side of the frame 101. The baffle 201 can be picked up to embed the sliders 202 on both sides into the inside of the slide groove 2, and the baffle 201 can be pushed to make the sliders 202 slide on the inner surface of the slide groove 2.

[0027] Further, such as Figure 1-5 As shown, sliders 202 are slidably connected on both sides of the inside of the two slide grooves 2, and a first dustproof net 112 is fixedly installed on the rear side of the inner wall of the heat dissipation device 107 and in front of the multiple first air inlets 111. The four sliders 202 are divided into two groups, so that the rotating fan 108 can suck air through the first air inlet 111 when it is running, and the wind is transported to the rear side of the partition 205 through the first dustproof net 112.

[0028] Further, such as Figure 1-5 As shown, a baffle 201 is fixedly installed inside the two sets of sliders 202 and at the rear side of the backlight module 102 , and threaded holes 203 are provided around the rear side of the frame 101 , so that the baffle 201 can fit the rear side of the backlight module 102 .

[0029] Further, such as Figure 1-5 As shown, the two baffles 201 are both threadedly connected with second bolts 204, and a partition 205 is movably embedded inside the shell 1 and at the rear side of the backlight module 102. The second bolt 204 can be rotated to be embedded into the threaded hole 203 through the baffle 201, thereby fixing the backlight module 102.

[0030] Further, such as Figure 1-5 As shown, the front outer surfaces of the four second bolts 204 are threadedly connected to the inner surface of the threaded hole 203, and a plurality of second air inlets 206 are opened inside the partition 205. The outer surface of the pipe joint 110 is movably embedded in the interior of the partition 205. The rotating fan 108 can be used to blow air so that the wind passes through the second air inlets 206 and blows to the rear side of the backlight module 102 to dissipate heat therefrom.

[0031] See also Figure 1-5A display includes a display screen 209, which is fixedly embedded in the front side of the interior of a shell 1. Air outlets 207 are provided on both sides of the interior of the shell 1. Second dustproof nets 208 are fixedly installed on both sides of the interior of the shell 1 and on the inner sides of the air outlets 207. Hot air can be evacuated through the air outlets 207, and the hot air can be evacuated from the interior of the shell 1 through the second dustproof net 208. At the same time, the display screen 209 is started through the power supply system of the display screen 209, and the backlight module 102 is started synchronously through the power supply system of the backlight module 102, so that the backlight module 102 provides uniform lighting behind the display screen 209 when it is running, so that the content of the display screen 209 can be clearly displayed.

[0032] Working principle: the staff can first start the display screen 209 through the power supply system of the display screen 209, and then start the backlight module 102 synchronously through the power supply system of the backlight module 102, so that the backlight module 102 provides uniform lighting behind the display screen 209 when it is running, so that the content of the display screen 209 can be clearly displayed, and when the display is used for too long and overheats, the staff can start the rotating fan 108 through the driving system of the rotating fan 108 inside the heat dissipation device 107, so that the rotating fan 108 sucks air through the first air inlet 111 when it is running, so that the wind is transported to the rear side of the partition 205 through the first dustproof net 112, and then blows air through the rotating fan 108, so that the wind blows to the backlight module 10 through the second air inlet 206 2, and then the heat is blown and cooled by the rear side, and then the hot air is evacuated through the air outlet 207, so that the hot air is evacuated out of the interior of the housing 1 through the second dustproof net 208. When the heat dissipation device 107 is blowing and cooling, a part of the wind is drawn out through the air outlet duct 109, and the wind is transported to the interior of the cooling copper tube 104 through the duct joint 110, and then the heat of the backlight module 102 is absorbed by the cooling copper tube 104 in the placement groove 103, so that when the wind circulates in the cooling copper tube 104, the heat inside the cooling copper tube 104 is driven. The heat dissipation efficiency can be effectively improved by setting the structures of the heat dissipation device 107 and the cooling copper tube 104, and the heat of the backlight module 102 is absorbed by the cooling copper tube 104, so as to further improve the heat dissipation efficiency and ensure the stability and reliability of the entire heat dissipation system. When in use, the staff can first put the backlight module 102 into the frame 101, then pick up the baffle 201, so that the sliders 202 on both sides are embedded in the inside of the slide groove 2, and push the baffle 201 to make the sliders 202 slide on the inner surface of the slide groove 2, so that the baffle 201 fits the back side of the backlight module 102, and rotate the second bolt 204 to make the second bolt 204 pass through the baffle 201 and embed into the inside of the threaded hole 203, so as to fix the backlight module 102. When the frame 101 is assembled, the frame 101 can be picked up to make the sliders 202 embedded in the housing 1 The first embodiment of the present invention is to firstly install the first bolt 106 in the housing 1 and locate it at the rear side of the display screen 209, then pick up the partition 205, embed it into the housing 1 and locate it at the bottom of the frame 101, then pick up the cover 105, cover the cover 105 to the rear side of the housing 1, connect the air outlet duct 109 with the duct joint 110, then rotate the first bolt 106, embed it into the housing 1, and assemble the display. Through the baffle 201 and other structures, when the display is in use, not only the assembly process is made simpler and faster, but also the stability and reliability of the display are guaranteed.
