Each liquid cold plate performs heat dissipation tasks independently, and uses mechanical circulation instead of cooling medium circulation. Through the vertical conveying device and the horizontal conveying device, the liquid cold plate that has been cooled in the cold plate cooling device can be sent to the liquid cooling cabinet to absorb the heat on the server surface; at the same time, the liquid cold plate with too high temperature in the liquid cooling cabinet is sent to the cold plate cooling device for cooling. The present invention adjusts the number of liquid cold plate modules placed on the server surface in real time according to the actual heat load of the server, avoids the problem of cooling liquid leakage and energy waste caused by excessive cooling, and improves the safety and reliability of the system.

[0022] The bottoms of the two baffles 212 are in contact with the top of the server rack 1 , and are used to limit the position of the frame body 211 .

[0023] In this embodiment, the rotating unit 21 further includes a driving motor 216 fixedly mounted on the rear side of the mounting plate 213 . The output end of the driving motor 216 passes through the mounting plate 213 and is fixedly mounted with a second gear 217 . The second gear 217 is meshed with the first gear 215 .

[0024] The model of the driving motor 216 is KV3SF-8521F-WR, which is electrically connected to an external power supply and is opened and closed by a person operating the control panel. The operation of the driving motor 216 drives the second gear 217 to rotate, and the second gear 217 drives the first gear 215 to rotate the rotating tube 214, and the rotating tube 214 drives the brush assembly 4 to rotate, and the bristles of the dust removal brush 43 clean the dust on the filter pores of the server rack 1.

[0025] In this embodiment, the brush assembly 4 includes a rotating seat 41 fixedly installed at the front end of the rotating tube 214, and two slots 42 are provided inside the rotating seat 41. A dust removal brush 43 is installed inside the slot 42 through a clamping block. A front plate of the rotating seat 41 is provided with a plurality of air outlet holes 44, and a front plate of the frame 211 is provided with filter holes, and the brush surface of the dust removal brush 43 is in contact with the filter holes.

[0026] The dust brush 43 is slidably inserted into the slot 42 through the card block, so that the dust brush 43 is clamped with the rotating seat 41, thereby making the installation and removal process of the dust brush 43 quick and simple, reducing the time required for replacing the dust brush 43 and improving work efficiency.

[0027] In this embodiment, the air pump unit 22 includes an air pump 221 fixedly mounted on the left wall of the inner cavity of the frame 211 , a conduit 222 is fixedly mounted on the output end of the air pump 221 , and one end of the conduit 222 away from the air pump 221 is rotatably connected to the rear end of the rotating tube 214 .

[0028] The air pump 221 is of model RB-1010, which is electrically connected to an external power source and is turned on and off by a person operating the control panel. The air pump 221 blows out gas, which enters the interior of the rotating seat 41 through the conduit 222 and the rotating tube 214, and then blows on the surface of the filter pores through the air outlet 44 to blow out the cleaned dust, thereby preventing the filter pores from being blocked. In this embodiment, the disassembly and assembly unit 23 includes a mounting frame 231 fixedly mounted on the front wall of the inner cavity of the frame 211, a pull rod 232 is slidably mounted through the front plate of the frame 211, both ends of the pull rod 232 are fixedly mounted with plug blocks 234, and one end of the plug block 234 is an inclined surface, and the outer ring of the pull rod 232 is provided with a spring 233, and the disassembly and assembly unit 23 also includes a socket plate 235 fixedly mounted on the top of the server rack 1, and the inclined end of the plug block 234 is slidably inserted into the interior of the socket plate 235.

[0029] When the frame 211 is buckled on the top of the server rack 1, the plug block 234 contacts the top of the socket plate 235 through the inclined surface, and the socket plate 235 squeezes the plug block 234. After the frame 211 reaches the fixed position, the spring 233 pushes the plug block 234 to slide into the inside of the socket plate 235 through its own elastic force. The user pulls the pull rod 232, and the pull rod 232 drives the two plug blocks 234 to move synchronously. The plug block 234 squeezes the spring 233, and the plug block 234 slides out of the inside of the socket plate 235, thereby realizing the rapid disassembly and assembly of the frame 211, which is convenient for repairing and replacing parts of the cleaning mechanism 2.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] When working, the user first connects the device to an external power source, and then buckles the cleaning mechanism 2 on the top of the server rack 1 through the frame 211. At this time, the plug block 234 contacts the top of the socket plate 235 through the inclined surface, and the socket plate 235 squeezes the plug block 234. After the frame 211 reaches the fixed position, the spring 233 pushes the plug block 234 to slide and snap into the inside of the socket plate 235 through its own elastic force. Then the driving motor 216 runs to drive the second gear 217 to rotate, and the second gear 217 drives the first gear 215 to rotate the rotating tube 214, and the rotating tube 214 drives the brush assembly 4 to rotate, and the bristles of the dust removal brush 43 clean the dust on the air holes of the filter screen of the server rack 1. At the same time, the air pump 221 runs to blow out gas, and the gas passes through the conduit 222 and the rotating tube 2 14 enters the interior of the rotating seat 41, and then blows the cleaned dust out on the surface of the filter pores through the air outlet 44. When disassembling the cleaning mechanism 2, the user pulls the pull rod 232, and the pull rod 232 drives the two plug blocks 234 to move synchronously. The plug block 234 squeezes the spring 233, and the plug block 234 slides out of the interior of the jack plate 235, thereby realizing the rapid disassembly and assembly of the frame 211, and the cleaning mechanism 2 is repaired and replaced with parts. Then, when replacing the dust brush 43, the card block of the dust brush 43 slides out of the interior of the card slot 42, so that the dust brush 43 and the rotating seat 41 are separated, and the new dust brush 43 is slid into the interior of the card slot 42 through the card block, so that the dust brush 43 and the rotating seat 41 are clamped together, and the replacement of the dust brush 43 is completed.
