[0023] Considering that the brightness improvement of the high-brightness LED screen body 1 mainly depends on the increase in the number and power of the backlight tubes, more heat will be generated. In order to improve the heat dissipation efficiency of the high-brightness LED screen body 1, a circular groove 3 is provided on the back shell 2, and a cylinder 4 is fixedly connected inside the circular groove 3. A coil 5 is fixedly connected to the inner wall of the back shell 2, and the coil 5 is connected to the cylinder 4. The structural characteristics of the coil 5 can be set according to the distribution characteristics of the heat-prone structure inside the high-brightness LED screen body 1. A detection heat dissipation component is provided on the coil 5, and the detection heat dissipation component is set to multiple groups, and the multiple groups of detection heat dissipation components are set at a small pitch to ensure the uniformity of heat dissipation.

The multiple groups of detection heat dissipation components correspond to the multiple groups of heat-prone structures inside the high-brightness LED screen body 1 one by one, thereby improving the pertinence of heat dissipation. Specifically, a controller may be provided to be connected between the temperature sensor 7 and the solenoid valve 16. When the temperature sensor 7 detects that the stability of the corresponding area exceeds a set threshold, the solenoid valve 16 is opened through the controller to achieve targeted heat dissipation.

[0024] The cylinder 4 is provided with an air supply assembly, which includes a support plate 8, a fan 9, a motor 10 and a rotating shaft 15.
