The sliding board 501 is used to cover the top of the display module 3, thereby preventing the top display module 3 from exiting the interior of the installation frame 1.

[0045] When the display module 3 is to be cooled, the water pump 603 is started, and the input end of the water pump 603 draws the cooling liquid inside the water tank 601 into the connecting elbow 604, and completes the circulation of the cooling liquid in the cooling pipe 605, and then the cooling pipe 605 can be used to complete the heat dissipation of the display module 3. At the same time, the water pipe 213 is filled with water through the output end of the water pump 603, so that it can pass into the interior of the water-passing installation strip 201, so as to replenish water for the water-dipping roller 211.
