By further setting the rotation direction of the liquid cooling belt 300, the movement direction of the liquid cooling belt 300 toward one side of the LED screen 100 is opposite to the flow direction of the air current, and this setting is because, after the air current enters the air duct 210, the air temperature of the air current will gradually rise along with the movement of the air current, that is, the temperature of the air current is lower than the temperature of the air current after the air current flows just after entering the air duct 210, and the liquid cooling effect of the surface of the liquid cooling belt 300 is better than that of the liquid cooling belt 300 after the liquid cooling belt 300 is cooled by the liquid cooling box 400 for a period of time, so that the heat of the air current is neutralized as a whole by making the movement direction of the liquid cooling belt 300 toward one side of the LED screen 100 opposite to the flow direction of the air current, and the uniformity of the whole heat dissipation is improved.

In this embodiment, by providing the rotor blade 260, when the third motor is started, the rotor blade 260 is driven to rotate, so as to pressurize the air flow in the air channel 210, and help the air flow circulate. That is, when the air flows in the spiral air duct 210, the air flows first through one side of the liquid cooling belt 300, then through the other side of the liquid cooling belt 300 after being pressurized by the rotating blade 260, and finally is discharged from the air outlet 203, thereby radiating the heat of the LED screen 100.
By combining the above embodiments, the specific working principle and working process are as follows:
When the air pump is used, the second motor, the third motor and the air pump are started firstly, the air pump is used for supplying air to the air inlet 202, when the air flow is conveyed from the head end of the air channel 210 to the tail end along the first direction, the air flow is in spiral flow in the air channel 210, so that the air is more uniformly mixed and flows in the pipeline, the situation that the local flow velocity is uneven is avoided, and the liquid cooling belt 300 is driven to rotate around the second direction due to the fact that the second motor is started to drive the liquid cooling belt 300 to cool by the cooling liquid after passing through the cooling liquid, then the air flow passing through the surface of the liquid cooling belt 300 is cooled, and the air flow can be continuously cooled along with continuous rotation of the liquid cooling belt 300, the third motor is started to drive the rotating blade 260 to rotate, the air flow in the air channel 210 is pressurized, and the air flow circulation is assisted. That is, when the air flows in the spiral air duct 210, the air flows first through one side of the liquid cooling belt 300, then through the other side of the liquid cooling belt 300 after being pressurized by the rotating blade 260, and finally is discharged from the air outlet 203, thereby radiating the heat of the LED screen 100. The reciprocating circulation is performed in this way, so that the temperature of the air flow blown onto the LED screen 100 is lower, and the heat dissipation effect and the heat dissipation uniformity of the LED screen 100 are improved.
By further setting the rotation direction of the liquid cooling belt 300, the movement direction of the liquid cooling belt 300 toward one side of the LED screen 100 is opposite to the flow direction of the air current, and this setting is because, after the air current enters the air duct 210, the air temperature of the air current will gradually rise along with the movement of the air current, that is, the temperature of the air current is lower than the temperature of the air current after flowing just after entering the air duct 210, and the liquid cooling effect of the surface of the liquid cooling belt 300 is better than the liquid cooling effect after the liquid cooling belt 300 rotates for a period of time just after the liquid cooling belt 300 cools, so that the air current is neutralized as a whole by making the movement direction of the liquid cooling belt 300 toward one side of the LED screen 100 opposite to the flow direction of the air current, and the uniformity of the whole heat dissipation is improved.
In the use process, the first motor driving shell 200 is started to move along the LED screen 100, so that the heat dissipation of the whole LED screen 100 can be improved, and all parts of the LED screen 100 can uniformly dissipate heat. And the heat radiation efficiency and the heat radiation effect can be improved by reducing the moving speed of the housing 200, improving the supply speed of the air flow, improving the rotation speed of the rotating blade 260, or improving the rotation speed of the liquid cooling belt 300.
