At the same time, as Figure 7As shown, the L-shaped groove 11 facilitates the insertion of the fingers into the interior thereof, thereby facilitating the pushing of the sliding plate 12.

[0041] Working principle:

[0042] In use, first, the two limiting blocks 18 at the bottom of the lamp plate 3 are inserted into the two limiting grooves 17 at the top of the backlight plate 1, thereby preliminarily fixing the lamp plate 3 on the top of the backlight plate 1.

[0043] Then, the sealing cover at the top of the filling pipe 19 is opened, and the inside of the mounting frame 5 is filled with cooling liquid through the filling pipe 19. After the filling is completed, the sealing cover is closed. Then, the clamping blocks 15 at the two ends of the bottom of the mounting frame 5 are inserted into the clamping grooves 10. When the inclined surface of the bottom of the clamping block 15 contacts the inclined surface of the end of the clamping block 14, the clamping block 15 is continuously inserted, and under the action of the force, the clamping block 14 moves, and simultaneously, the sliding plate 12 moves in the L-shaped groove 11, and the spring 13 is compressed. When the clamping block 15 is inserted to the specified depth, i.e., when the two ends of the bottom of the mounting frame 5 contact the top of the mounting frame strip 2, the clamping groove 16 is located on the side of the clamping block 14 at this time. Under the elastic force of the spring 13, the sliding plate 12 and the clamping block 14 are reset, the clamping block 14 enters the inside of the clamping groove 16, thereby quickly completing the installation operation of the clamping block 15 and the mounting frame 5. At this time, the right-angle plate 9 at the bottom of the mounting frame 5 contacts one side of the inner wall of the groove 4.

[0044] When the device is working, the MCU board 6 controls the lamp bead control board 7 to work, and the lamp bead control board 7 controls the plurality of lamp bead bodies 8 to emit light. At the same time, the right-angle plate 9 contacts the inner wall of the groove 4, thereby transferring the heat generated by the lamp plate 3 during work. In addition, the cooling liquid in the right-angle plate 9 quickly cools the heat on the right-angle plate 9, and the flow of external air can take away the heat on the right-angle plate 9, thereby achieving the purpose of double heat exchange, and effectively ensuring the heat dissipation effect of the device.

[0045] When the device needs to be maintained, the finger can be inserted into the inside of the L-shaped groove 11, and the sliding plate 12 is actuated to move the clamping block 14, and the spring 13 is pressed to make the clamping block 14 disengage from the inside of the clamping groove 16, and then the installation frame 5 and the clamping block 15 can be taken out upward, so that the quick disassembly operation is completed, the traditional screw installation mode is avoided, the installation and disassembly efficiency is improved, the occurrence of the thread stripping phenomenon is avoided, and the actual application and operation are facilitated.

[0046] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
