Description

Technical Field

[0001] The present invention relates to the technical field of liquid cooling, and particularly to an immersion-type insulating liquid liquid cooling device and a liquid cooling method thereof. Background Art

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figures 1-6, A submerged insulating liquid liquid cooling device, comprising a housing 5 and a carrier plate 14. A guide rod 8 slidably connected to the carrier plate 14 is fixed between the top inner wall and the bottom inner wall of the housing 5 by bolts. A self-locking electric telescopic rod 11 for driving the carrier plate 14 to move up and down is fixed to the top outer wall of the housing 5 by bolts. A notch is formed in the top of the housing 5. A sealing assembly 4 for sealing the notch is provided on the top of the carrier plate 14. The sealing assembly 4 includes two connecting frames 13 fixed to the top of the carrier plate 14 by bolts. A cover plate 10 is fixed to the tops of the two connecting frames 13 by bolts. A sealing ring 9 is adhered to the bottom of the cover plate 10. A groove 12 for clamping the sealing ring 9 is formed in the top outer wall of the housing 5. Then the battery is installed on the carrier plate 14. Then the self-locking electric telescopic rod 11 is started. The piston end of the self-locking electric telescopic rod 11 extends, causing the carrier plate 14 to reset. At the same time, the sealing ring 9 will be inserted into the groove 12, thereby achieving the sealing of the housing 5. This not only prevents dust from entering the insulating liquid in the housing 5 and affecting the quality of the insulating liquid, but also avoids economic losses caused by the evaporation of the insulating liquid. A circulation assembly 1 communicating with the housing 5 is provided on one outer wall of the housing 5. A cooling assembly 2 communicating with the housing 5 and the circulation assembly 1 is provided on one outer wall of the housing 5 and at the top of the circulation assembly 1. The self-locking electric telescopic rod 11 is started. The piston end of the self-locking electric telescopic rod 11 contracts, thereby driving the carrier plate 14 to move upward. At the same time, the carrier plate 14 drives the sealing assembly 4 to move upward, causing the sealing assembly 4 to separate from the notch until the carrier plate 14 is moved to the position of the notch. Then the insulating liquid is added into the housing 5 through the gap between the notch and the carrier plate 14. Then the battery is installed on the carrier plate 14. Then the self-locking electric telescopic rod 11 is started. The piston end of the self-locking electric telescopic rod 11 extends, causing the sealing assembly 4 to reset. Then the circulation assembly 1 and the cooling assembly 2 are started simultaneously. Through the combined use of the circulation assembly 1 and the cooling assembly 2, the insulating liquid in the housing 5 is cooled, thereby greatly improving the cooling efficiency of the insulating liquid and avoiding the problem that the insulating liquid itself will gradually absorb heat and cause its temperature to rise, which will directly affect its cooling effect.

[0035] In the present invention, the circulation component 1 includes two liquid inlet pipes 6 welded to the outer wall of one side of the housing 5 and communicating with the housing 5. The other ends of the two liquid inlet pipes 6 are both welded with cylinders 7. The outer walls of one side of the two cylinders 7 are both welded with diversion pipes 21 communicating with the cylinders 7. The two diversion pipes 21 are both communicated with the cooling component 2. The inner walls of the two cylinders 7 are both slidably connected with piston blocks 31. One side of the housing 5 is provided with a driving component for driving the two piston blocks 31 to move simultaneously. The driving component includes a fixing frame 27 fixed to one side of the housing 5 by bolts and located on one side of the circulation component 1. A cylinder 28 is fixed to one side of the fixing frame 27 by bolts. A fixing rod 33 is fixed between the two piston blocks 31 by bolts. A fixing block 32 whose one side is fixed to the piston end of the cylinder 28 is provided on the outer side of the fixing rod 33 and at the bottom position. Stirring components 15 are provided on the inner walls of both sides of the housing 5. Starting the cylinder 28, the cylinder 28 drives the two piston blocks 31 to move to one side simultaneously through the fixing rod 33, thus greatly improving the working efficiency. Check valves 34 are provided on the two liquid inlet pipes 6 and the two diversion pipes 21. Starting the driving component, the driving component drives the two piston blocks 31 to move leftward simultaneously. One of the piston blocks 31 pushes the insulating liquid in one of the cylinders 7 into the cooling component 2 along one of the diversion pipes 21. At the same time, the other piston block 31 sucks the insulating liquid in the housing 5 into the other cylinder 7 along the other liquid inlet pipe 6. Starting the driving component again, the driving component drives the two piston blocks 31 to move rightward simultaneously. The other piston block 31 pushes the insulating liquid in the other cylinder 7 into the cooling component 2 along the other diversion pipe 21. At the same time, one of the piston blocks 31 sucks the insulating liquid in the housing 5 into one of the cylinders 7 along one of the liquid inlet pipes 6. And so on. At the same time, the check valves 34 can prevent the insulating liquid in the two liquid inlet pipes 6 and the two diversion pipes 21 from flowing backward, thus realizing the circulation of the insulating liquid. And through the cooperation of the two piston blocks 31, the insulating liquid is continuously pushed into the cooling component 2, thus greatly increasing the cooling efficiency of the insulating liquid.

[0036] Particularly, the stirring assembly 15 includes two connecting shafts 16 that are rotatably arranged between the inner walls on both sides of the housing 5 through bearings and are symmetrically arranged at the bottom. A plurality of stirring blades 17 are uniformly fixed to the outer sides of the connecting shafts 16 through bolts. One end of each of the two connecting shafts 16 passes through the housing 5 and is connected to a fixed block 32 through a transmission assembly. The transmission assembly includes two gears 30 that are respectively key-connected to the outer walls of the two connecting shafts 16. One side of the fixed block 32 is fixed with a rack 29 that meshes with the two gears 30 through bolts. When the fixed block 32 moves, it drives the rack 29 to move. The rack 29 drives the two gears 30 to rotate. The two gears 30 respectively drive the two rotating shafts 16 to rotate, thus realizing the transmission. The two connecting shafts 16 are driven to rotate simultaneously through the transmission assembly. The two connecting shafts 16 simultaneously drive the plurality of stirring blades 17 to rotate. The insulating liquid in the housing 5 is stirred by the stirring blades 17, effectively promoting the uniform mixing of the medium and avoiding the problem of uneven temperature distribution of the insulating liquid, thereby improving the overall cooling efficiency of the insulating liquid.

[0037] It should be particularly noted that the cooling assembly 2 includes two liquid outlet pipes 3 that are welded to the outer side of the housing 5 and are in communication with the housing 5 and are symmetrically arranged. The other ends of the two liquid outlet pipes 3 are welded with a first connecting pipe 18 that is in communication with the two liquid outlet pipes 3. One end of the first connecting pipe 18 is welded with a diversion shell 20 that is in communication with the first connecting pipe 18. The bottom of the diversion shell 20 is welded with a second connecting pipe 22 that connects the diversion shell 20 with two diversion pipes 21. A refrigeration assembly 19 is arranged at the middle position of the inner wall of the diversion shell 20. The refrigeration assembly 19 includes a fixing ring 24 that is fixed to the inner wall of the diversion shell 20 through bolts and is located at the middle position. A plurality of through holes 23 are formed in the top of the fixing ring 24. Two heat conducting plates 25 are welded to the circumferential inner wall of the fixing ring 24 at the top and bottom positions. A plurality of uniformly arranged semiconductor refrigeration chips 26 are fixed to the bottom of one of the heat conducting plates 25 and the top of the other heat conducting plate 25 through bolts. The model of the semiconductor refrigeration chip 26 is TEC1-12706. The heat of the insulating liquid in the diversion shell 20 is introduced onto the semiconductor refrigeration chips 26 through the two heat conducting plates 25. The heat is cooled by the semiconductor refrigeration chips 26. The insulating liquid enters the diversion shell 20 through the diversion pipes 21 and the second connecting pipe 22. At the same time, the insulating liquid in the diversion shell 20 is cooled by the refrigeration assembly 19. Then the cooled insulating liquid flows back into the housing 5 again through the first connecting pipe and the liquid outlet pipes 3, thereby cooling the insulating liquid in the housing 5 and greatly improving the cooling efficiency of the insulating liquid.

[0038] The present invention also proposes an immersion type insulating liquid liquid cooling method, including the following steps:

[0040] S2: Installation, start the self-locking electric telescopic rod 11. The piston end of the self-locking electric telescopic rod 11 contracts, driving the carrier plate 14 to move upward. At the same time, the carrier plate 14 drives the cover plate 10 to move upward through the connecting frame 13, causing the cover plate 10 to separate from the notch. Then, install the battery on the carrier plate 14. Next, start the self-locking electric telescopic rod 11. The piston end of the self-locking electric telescopic rod 11 extends, resetting the carrier plate 14. At the same time, the sealing ring 9 will insert into the groove 12.

[0041] S3: Circulation, start the cylinder 28. The cylinder 28 drives the two piston blocks 31 to move leftward simultaneously through the fixed rod 33. One of the piston blocks 31 pushes the insulating liquid in one of the cylinders 7 along one of the guide pipes 21 into the guide shell 20. The insulating liquid in the guide shell 20 passes through the through hole 23 and then flows back into the housing 5 through the first connecting pipe and the liquid outlet pipe 3. At the same time, the other piston block 31 pumps the insulating liquid in the housing 5 along the other liquid inlet pipe 6 into the other cylinder 7. Start the cylinder 28. The cylinder 28 drives the two piston blocks 31 to move rightward simultaneously through the fixed rod 33. The other piston block 31 pushes the insulating liquid in the other cylinder 7 along the other guide pipe 21 into the guide shell 20. The insulating liquid in the guide shell 20 passes through the through hole 23 and then flows back into the housing 5 through the first connecting pipe and the liquid outlet pipe 3. At the same time, one of the piston blocks 31 pumps the insulating liquid in the housing 5 along one of the liquid inlet pipes 6 into one of the cylinders 7, and so on.

[0042] S4: Cooling, the two heat conducting plates 25 conduct the heat of the insulating liquid in the guide shell 20 to the semiconductor refrigeration chip 26. The semiconductor refrigeration chip 26 cools the heat, thereby cooling the insulating liquid in the guide shell 20.
