Then start the exhaust fan to suck out the hot air inside the display body and discharge it through the heat dissipation holes to reduce uneven heat dissipation, improve heat dissipation effect, and reduce the impact on internal components.

2. When the motor is started, the inhaled air enters the bellows through the ventilation hole and then enters the display screen body. When the air is inhaled, it passes through the filter plate, which filters the dust in the air. When the filter plate needs to be cleaned, the S-shaped spring can be pulled to move out of the fixed groove, so that the S-shaped spring can rotate on the fixed column to release the restriction on the filter plate. Then the filter plate can be directly pulled out of the frame for cleaning, which reduces the dust from entering the display screen body and facilitates the staff to replace and clean the filter plate, reducing the impact of dust on internal components.

At the same time, the air entering the ventilation hole is filtered through the dust removal mechanism to reduce the dust from entering the display screen body 1 and the impact of dust on the internal components. Then, the cooling mechanism is used to dissipate the heat inside the display screen body 1 to reduce the uneven heat dissipation, improve the heat dissipation effect, and reduce the impact on the internal components.

The pumping assembly includes a liquid inlet pipe 15 fixed to the side of the lower end of the cooling box 11, a micro water pump 14 is fixed to the end of the liquid inlet pipe 15 away from the cooling box 11, the upper end of the micro water pump 14 is fixedly connected to the cooling pipe 13, and a cooling member is fixed to the side of the cooling pipe 13. The cooling member includes a heat sink 16 fixed to the side of the cooling pipe 13, the heat sink 16 is a metal plate, and the heat sink 16 is coated with thermal conductive silica gel, and exhaust fans 17 are fixed to the inner walls of both sides of the display screen body 1, and the exhaust fans 17 correspond to the heat dissipation holes.

After the addition is completed, the support plate 7 is reset. When heat dissipation begins, the micro water pump 14 is started, and the coolant in the cooling box 11 is extracted through the liquid inlet pipe 15.

At the same time, the heat dissipation plate 16 conducts heat to the internal components of the display screen body 1, and the heat dissipation silica gel improves the heat conduction effect. The dissipated heat is absorbed by the coolant in the cooling pipe 13 and enters the cooling box 11 through circulation. At the same time, the cooling pipe 13 is U-shaped to increase the circulation time and make the heat dissipation more uniform.

The support column 1 2 is rotatably connected to the support column 2 3.

When the liquid crystal display screen is in use, the angle of the display screen body 1 is adjusted by rotating the support column 23, which is convenient for the staff to use. When the motor 9 is started, the inhaled air enters the bellows 8 through the ventilation hole and then enters the display screen body 1. When the air is inhaled, the air passes through the filter plate 19, and the filter plate 19 filters the dust in the air to reduce the dust from entering the display screen body 1. When the filter plate 19 needs to be cleaned, the S-shaped spring piece 21 can be pulled to move out of the fixed groove, so that the S-shaped spring piece 21 rotates on the fixed column 20 to release the restriction on the filter plate 19, and then the filter plate 19 is directly pulled out of the frame 18. After cleaning, the filter plate 19 is inserted back and the S-shaped spring piece 21 is rotated to enter the fixed groove, which is convenient for the staff to replace and clean the filter plate 19.

The implementation principle of a heat dissipation liquid crystal display screen of this embodiment is as follows: when the liquid crystal display screen is in use, the staff turns on the display screen body 1 for imaging through an external power supply. When the display screen body 1 is working, the angle of the display screen body 1 can be adjusted by rotating the support column 2 3, and then the bolts on the support plate 7 are unscrewed, and then coolant is added through the feeding port 12 on the cooling box 11. After the addition is completed, the support plate 7 is reset. When heat dissipation begins, the motor 9 is started, and the motor 9 drives the fan blades 10 to rotate to generate wind force, so as to cool down the internal components of the display screen body 1 and reduce the internal temperature from overheating. When the motor 9 is started, the inhaled air enters the bellows 8 through the ventilation hole and then enters the display screen body 1. When the air is inhaled, the air passes through the filter plate 19, and the filter plate 19 filters the dust in the air to reduce the dust from entering the display screen body 1.

At the same time, the micro water pump 14 is started, and the coolant in the cooling box 11 is extracted through the liquid inlet pipe 15. The extracted coolant enters the cooling pipe 13 through the water outlet end of the micro water pump 14. At the same time, the heat sink 16 conducts heat to the internal components of the display screen body 1, and the heat dissipation silica gel improves the heat conduction effect. The dissipated heat is absorbed by the coolant in the cooling pipe 13 and re-enters the cooling box 11 through circulation. At the same time, the cooling pipe 13 is U-shaped to increase the circulation time and make the heat dissipation more uniform. The wind force of the fan blades 10 is driven by the motor 9 to blow and cool the coolant in the cooling pipe 13 and the cooling box 11, and then the exhaust fan 17 is started to suck out the hot air inside the display screen body 1 and discharge it through the heat dissipation holes;
