As shown in fig. 1, 2 and 3, an embodiment of the installation box for a display screen includes a box 100, an air supply module 300 and a support 200 disposed in the box 100.

An opening 120 is formed in one side of the box body 100, a first ventilation channel 110 is formed in a side plate of the box body 100, and an air inlet hole 140 communicated with the first ventilation channel 110 is formed in the outer wall of the box body 100; the air supply module 300 is arranged at the air inlet hole 140; the supporting member 200 includes a supporting side 220 opposite to the opening 120 and an air exhausting side 230 opposite to the supporting side 220, the supporting member 200 is provided with a plurality of heat dissipating ports 210 penetrating through the supporting side 220 and the air exhausting side 230, the supporting member 200 is further provided with a second ventilating channel 240 communicating with the first ventilating channel 110, and the side walls of all the heat dissipating ports 210 are provided with first ventilating holes 211 communicating with the second ventilating channel 240.

When the mounting box of the display screen is used for mounting the LED display screen 700, the circuit board of the LED display screen 700 is attached to the supporting side 220. When heat dissipation is needed, the air supply module 300 is started, the air supply module 300 can sequentially convey cold air to the first ventilation channel 110 and the second ventilation channel 240, then the cold air can be blown to each part of the circuit board corresponding to each heat dissipation port 210 from the first ventilation holes 211 on each heat dissipation port 210, and finally the cold air absorbing heat of the circuit board can be discharged from each heat dissipation port 210 on the air exhaust side 230, so that the temperature of each part of the circuit board is reduced. Thus, the cold air can act on each part of the circuit board independently, thereby avoiding the problem of poor heat dissipation effect of the part of the circuit board far away from the air supply module 300.

The supporting member 200 is detachably connected to the inner wall of the box 100, and specifically, the supporting member 200 is screwed to the box 100. In this manner, the mounting of the support member 200 is facilitated.

As shown in fig. 1 and 3, in some embodiments, the inner wall of the case 100 is provided with a second vent hole 130 communicating with the first vent passage 110; wherein the first and second ventilation holes 211 and 130 are used to guide cool air to be blown toward the front and rear sides of the display screen, respectively, in a state where the support 200 supports the display screen. When the LED display screen 700 installed in the installation box needs to dissipate heat, the air supply module 300 is started, the air supply module 300 can deliver cold air into the first ventilation channel 110, then a part of the cold air enters the second ventilation channel 240, and is blown from the first ventilation holes 211 on the respective heat dissipation ports 210 to the parts on the rear side of the LED display screen 700 corresponding to the respective heat dissipation ports 210, and finally is discharged from the respective heat dissipation ports 210 on the air exhaust side 230; a part of the cool air is directly blown toward the front side of the LED display screen 700 from the second ventilation holes 130 and then discharged from the opening 120. Thus, the cold air acts on the front and rear sides of the LED display screen 700, respectively, so that the heat dissipation effect of the LED display screen 700 is better.

It should be noted that the front side of the LED display screen 700 is composed of a plurality of LED modules, and the rear side of the LED display screen 700 is formed by a plurality of circuit boards electrically connected to the LED modules. When the LED display screen 700 is connected to the supporting member 200, the circuit board of the LED display screen 700 is attached to the supporting side 220.

After exiting from the second vent holes 130, the cool air flows down through the front side of the LED display panel 700 under the guidance of the vent gap 610, and is then discharged from the air outlet 611. Thus, while ensuring the heat dissipation performance of the front side of the LED display screen 700, the transparent cover plate 600 can prevent rainwater from flowing down to the LED display screen 700 from the opening 120, thereby improving the waterproof performance of the installation box of the display screen.

The transparent cover plate 600 is matched with the opening 120 in an opening and closing mode, specifically, a cylindrical pin is arranged on the transparent cover plate 600, a pin hole is formed in the box body 100 at the position of the opening 120, and the transparent cover plate 600 is hinged to the box body 100. In this manner, the transparent cover 600 is easily opened.

Further, the air outlet 611 is horizontally disposed near the bottom of the case. Thus, rainwater can be prevented from flowing into the ventilation gap 610 through the air outlet 611.

As shown in fig. 1 and 3, in the present embodiment, a door 500 is disposed on a side of the cabinet 100 opposite to the opening 120, and an exhaust hole 510 is disposed on the door 500. When the circuit board of the LED display screen 700 needs to be repaired, the LED display screen 700 does not need to be detached from the supporting member 200, the door 500 is opened for the repair, and the hot air flowing out of the heat dissipating port 210 is exhausted from the exhaust hole 510 into the box body 100. Thus, through the arrangement of the box door 500 and the air exhaust hole 510, the circuit board of the LED display screen 700 is convenient to overhaul and the temperature in the box body 100 can be effectively reduced.

As shown in fig. 2, specifically, the air supply module 300 includes a fan and a refrigeration unit, the fan and the refrigeration unit are both disposed in the air inlet hole 140, and the refrigeration unit is disposed between the fan and the first ventilation channel 110.

Thus, rainwater can be prevented from flowing into the box 100 from the air inlet 411.

Further, a filter screen is arranged at the air inlet 411. Thus, the insects and mice can be prevented from entering the box 100 from the air inlet 411.

As shown in fig. 2, in some embodiments, air supply module 300 further includes a water absorbent mesh disposed between the refrigeration unit and first ventilation channel 110. So, the net that absorbs water can absorb the drop of water in the cold air to avoid the drop of water to blow to the circuit board along with the cold air.

As shown in FIG. 4, in some embodiments, the area of the heat sink 210 on the support side 220 is greater than the area of the heat sink 210 on the exhaust side 230 for each heat sink 210. Thus, the cool air directly blows on the circuit board after flowing out of the first vent hole 211. Thereby make cold air can fully contact with the circuit board, and then make the radiating effect of circuit board better.

In which the arrows shown in fig. 4 indicate the flow direction of the cool air.

Therefore, the LED module has good heat dissipation performance when the heat dissipation effect of each part of the circuit board is good, and the heat dissipation performance of the LED display screen 700 device is better.

As shown in fig. 4, further, heat conducting members 710 are disposed on portions of the circuit board corresponding to the respective heat dissipating openings 210, and when the circuit board is attached to the supporting side 220, the heat conducting members 710 are inserted into the respective heat dissipating openings 210 in a one-to-one correspondence. Specifically, the heat conducting assembly 710 includes a plurality of heat conducting posts 711. Thus, the surface area of the circuit board contacting with the cold air is increased by the arrangement of the heat conduction columns 711, so that the heat dissipation effect of the circuit board is better.
