Description

Technical Field

[0001] This invention relates to the field of heat dissipation device technology, specifically to an integrated liquid cooling heat dissipation device and system for computing server rooms. Background Technology

[0002] Computing servers generate a lot of heat during operation, requiring effective heat dissipation to ensure normal operation. Liquid cooling is a commonly used cooling method in existing server rooms. Liquid cooling devices dissipate heat from the server by directly contacting the heat source with cold plates, resulting in significant cooling effects. However, it also has some shortcomings. In actual operation, it is not possible to easily add or remove cold plates as the number of servers increases or decreases, and it is not easy to easily remove and repair a faulty cold plate. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated liquid cooling heat dissipation device and system for computing server rooms, so as to solve the problems mentioned in the background art that the existing liquid cooling heat dissipation devices cannot easily add or remove corresponding cold plates according to the increase or decrease of servers, and cannot be easily installed, removed and repaired when a certain cold plate fails.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An integrated liquid cooling heat dissipation device for a computing server room includes: a liquid storage tank, on which first liquid cooling pipes are symmetrically fixedly arranged, and on which second liquid cooling pipes are fixedly arranged, and on which one of the first liquid cooling pipes is a circulation pump is fixedly connected, and on which the other first liquid cooling pipe is a heat exchanger is fixedly connected. A liquid cooling branch pipe is fixedly installed on the second liquid cooling pipe, and two opposite liquid cooling branch pipes form a group, and a connecting pipe head is fixedly installed on the liquid cooling branch pipe; A cold plate is installed on the liquid cooling manifold, and the cold plate connects two liquid cooling manifolds in a set. A pipe head sealing assembly is installed on the liquid cooling manifold and is used to seal the connecting pipe head. The plate locking assembly is also installed on the liquid cooling manifold and is movably connected to the pipe head sealing assembly. The pipe head sealing assembly drives the plate locking assembly to move, and the plate locking assembly locks the cold plate, thus fixing the cold plate on the liquid cooling manifold.

[0005] Furthermore, two mating insertion tubes are symmetrically fixedly arranged on the cold plate.

[0006] Furthermore, the pipe head sealing assembly includes: a connecting pipe ring, which is installed on the connecting pipe head; Anti-displacement strip, which is movably installed on the liquid cooling manifold.

[0007] Furthermore, the fitting tube engages with the connecting ring to connect the cold plate and the liquid cooling manifold, thereby enabling the connection of two liquid cooling manifolds in a set.

[0008] Furthermore, an inner support plate is fixedly installed inside the connecting pipe ring, an assembly support rod is fixedly installed on the inner support plate, and a sealing cap is fixedly installed on the assembly support rod. The connecting pipe head is sealed by the cooperation of the sealing cap and the connecting pipe head.

[0009] Furthermore, an anti-slip block is fixedly installed on the anti-slip strip. When the sealing cap closes the connecting pipe head, the anti-slip block supports the connecting pipe ring to ensure the stability of the sealing cap in closing the connecting pipe head.

[0010] Furthermore, the plate locking assembly includes: a movable support platform, which is movably mounted on the liquid cooling manifold and movably connected to the connecting pipe ring, and the movable support platform is moved by the connecting pipe ring; The movable support frame is movably connected to a limiting strip. The limiting strip locks the cold plate in place by cooperating with the cold plate, thus fixing it to the liquid cooling manifold.

[0011] Furthermore, an auxiliary support bar is fixedly installed on the movable support platform to provide auxiliary support for the cold plate and ensure its installation stability.

[0012] Furthermore, the movable support frame is mounted on the auxiliary support frame, and the movable support platform is locked by the movable support frame.

[0013] An integrated liquid cooling heat dissipation device control system includes a central controller module, a communication module, an adjustment module, and a control module. The central controller module issues commands to the adjustment module and the control module through the communication module. The adjustment module adjusts the flow rate, and the control module controls the operation of the circulating pump and the heat exchanger.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. Multiple liquid cooling sub-pipes are installed on the second liquid cooling pipe. A cold plate can be installed on each group of liquid cooling sub-pipes to achieve individual correspondence between the cold plate and the server, ensuring the heat dissipation effect of each server. When a group of liquid cooling sub-pipes is not equipped with a cold plate, the liquid cooling sub-pipe is in the disconnected state, but it will not affect the normal use of other groups of liquid cooling sub-pipes. The number of cold plates can be increased or decreased according to actual working needs, making it highly practical.

[0015] 2. When installing the cold plate, align the guide indicator rod with the guide cavity, and then move the cold plate downwards to achieve automatic locking installation of the cold plate. It can also achieve automatic connection between the cold plate and the liquid cooling manifold. At the same time, the cold plate can be further supported by the auxiliary support bar to ensure the stability of the cold plate during use. The operation is simple, convenient and quick.

[0016] 3. When disassembling the cold plate, simply pull the limiting strip to unlock it. Move the cold plate upwards to quickly remove it, enabling convenient installation and removal of the cold plate and facilitating its inspection or maintenance. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This invention provides a technical solution: like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an integrated liquid cooling heat dissipation device for a computing server room includes: a liquid storage tank 1, a cold plate 4, a pipe head sealing assembly, and a plate locking assembly. A first liquid cooling pipe 11 is symmetrically fixedly connected to the liquid storage tank 1, and a second liquid cooling pipe 12 is fixedly connected to the first liquid cooling pipe 11. A circulation pump 2 is fixedly connected to one of the first liquid cooling pipes 11, and a heat exchanger 3 is fixedly connected to the other first liquid cooling pipe 11. A liquid cooling branch pipe 13 is welded to the second liquid cooling pipe 12. Two opposing liquid cooling branch pipes 13 form a group, and a connecting pipe head 14 is welded and fixed to the liquid cooling branch pipe 13. The cold plate 4 is installed on the liquid cooling branch pipe 13, connecting the two liquid cooling branch pipes 13 in the group. The pipe head sealing assembly is installed on the liquid cooling branch pipe 13, sealing the connecting pipe head 14 to prevent coolant from overflowing from the connecting pipe head 14 when the cold plate 4 is not installed on the liquid cooling branch pipe 13.

[0037] The plate locking assembly is also installed on the liquid cooling manifold 13 and is movably connected to the pipe head sealing assembly. The pipe head sealing assembly drives the plate locking assembly to move, and the plate locking assembly locks the cold plate 4, thus fixing the cold plate 4 on the liquid cooling manifold 13.

[0038] like Figure 7 and Figure 16 As shown, the upper end of the connecting pipe head 14 is provided with a mating cavity 15, and an inner protruding bearing ring 16 is integrally formed and fixed inside the connecting pipe head 14. A sealing groove 17 is provided on the lower side of the inner protruding bearing ring 16. A support protrusion 18 is welded and fixed on the liquid cooling branch pipe 13 by welding process. A guide indicator rod 181 is welded and fixed on the support protrusion 18 by welding process. A protruding mounting platform 182 is symmetrically integrally formed and fixed on the support protrusion 18. A support moving hole 183 is provided on the protruding mounting platform 182. In addition, a limiting support platform 19 is welded and fixed on the protruding mounting platform 182 by welding process. An auxiliary insertion hole 191 is provided on the limiting support platform 19. A limiting channel 192 is provided on the limiting support platform 19. A mating support rod 193 is welded and fixed in the limiting channel 192 by welding process.

[0039] like Figure 9 As shown, two mating tubes 41 are symmetrically welded and fixed on the cold plate 4 by welding process. A mating guide strip 42 is also symmetrically welded and fixed on the cold plate 4 by welding process. A supporting mating cavity 43 is opened on the mating guide strip 42. The inner wall of the supporting mating cavity 43 is smooth and burr-free. A guide insertion cavity 44 is also opened on the mating guide strip 42. In addition, inclined protrusions 45 are symmetrically welded and fixed on the cold plate 4 on both sides of the mating guide strip 42 by welding process. The surface of the inclined protrusions 45 is smooth and burr-free.

[0040] like Figure 5 , Figure 6 , Figure 8 , Figure 10 , Figure 11 and Figure 12 As shown, the pipe head sealing assembly includes a connecting pipe ring 5 and an anti-slip strip 6. The connecting pipe ring 5 is installed on the connecting pipe head 14. Specifically, the connecting pipe ring 5 is partially inserted into the mating cavity 15. A sealing cavity 51 is opened at the upper end of the connecting pipe ring 5, and a supporting protrusion 55 is welded and fixed on the connecting pipe ring 5 by welding. A limiting through hole 56 is opened on the supporting protrusion 55, and a guide indicator rod 181 is inserted into the limiting through hole 56. A first spring 57 is sleeved on the guide indicator rod 181. The first spring 57 is located on the lower side of the supporting protrusion 55, and the upper end of the first spring 57 is welded and fixed to the lower end face of the supporting protrusion 55 by welding. The lower end of the first spring 57 is welded and fixed to the supporting protrusion 18 by welding. The guide indicator rod 181 and the limiting through hole 56 play a guiding and limiting role for the supporting protrusion 55.

[0041] In addition, a protruding wing plate 58 is symmetrically and integrally formed and fixed on the supporting convex plate 55, and a first movable swing rod 59 is hinged to the lower end of the protruding wing plate 58.

[0042] The anti-shifting strip 6 is movably installed on the liquid cooling manifold 13. Specifically, the lower end of the anti-shifting strip 6 has a support through hole 62, into which a matching support rod 193 is inserted. The surface of the anti-shifting strip 6 is smooth and burr-free. Its lower end is inserted into the limiting channel 192 and contacts the inner wall of the limiting channel 192. The inner wall of the limiting channel 192 is smooth and burr-free. A second spring 63 is sleeved on the matching support rod 193. One end of the second spring 63 is welded to the anti-shifting strip 6, and the other end is welded to the inner wall of the limiting channel 192. The matching support rod 193 and the support through hole 62 provide support and guidance for the anti-shifting strip 6, allowing the anti-shifting strip 6 to move only along the matching support rod 193. In addition, the contact between the anti-shifting strip 6 and the inner wall of the limiting channel 192 limits the movement of the anti-shifting strip 6, preventing it from tilting.

[0043] The fitting tube 41 cooperates with the connecting tube ring 5 to achieve the connection between the cold plate 4 and the liquid cooling branch pipe 13, thereby realizing the connection between the two liquid cooling branch pipes 13 in a set. Specifically, when the cold plate 4 and the liquid cooling branch pipe 13 are connected, the fitting tube 41 is partially inserted into the sealing cavity 51 on the connecting tube ring 5 to achieve a sealed connection between the connecting tube ring 5 and the fitting tube 41.

[0044] An inner support plate 52 is welded and fixed inside the connecting ring 5. An assembly support rod 53 is welded and fixed on the inner support plate 52. A sealing cap 54 is welded and fixed at the lower end of the assembly support rod 53. When the sealing cap 54 and the connecting pipe head 14 are cooperated to close the connecting pipe head 14, the sealing cap 54 is partially inserted into the sealing groove 17 on the inner convex support ring 16 to close the connecting pipe head 14.

[0045] An anti-slip block 61 is integrally formed and fixed on the anti-slip strip 6. The surface of the anti-slip block 61 is smooth and burr-free. When the sealing cap 54 closes the connecting pipe head 14, the anti-slip block 61 is located on the lower side of the protruding wing plate 58 and contacts the lower end face of the protruding wing plate 58. The anti-slip block 61 supports the connecting pipe ring 5, preventing the connecting pipe ring 5 from moving downward under the action of external force, and ensuring the stability of the sealing cap 54 in closing the connecting pipe head 14.

[0046] like Figure 5 , Figure 6 , Figure 13 , Figure 14 and Figure 15 As shown, the plate locking assembly includes a movable support 7 and a movable frame 8. The movable support 7 is movably mounted on the liquid cooling manifold 13 and movably connected to the connecting pipe ring 5. The movable support 7 is moved by the connecting pipe ring 5. Specifically, movable support rods 75 are symmetrically welded and fixed on the movable support 7 by welding. The movable support rods 75 are inserted into the support moving holes 183 on the protruding mounting platform 182. The cooperation between the support moving holes 183 and the movable support rods 75 provides support and guidance for the movable support 7, so that the movable support rods 75 can only move along the support moving holes 183. The movable support 7 is movably mounted on the liquid cooling manifold 13 by the cooperation between the movable support rods 75 and the support moving holes 183. In addition, a movable connecting block 76 is welded and fixed to the end of the movable support rod 75 away from the movable support 7 by welding. The movable connecting block 76 is hinged to the lower end of the first movable swing rod 59. The movable connection between the movable support 7 and the connecting pipe ring 5 is realized by the first movable swing rod 59.

[0047] A second movable swing rod 84 is hinged to the movable bar frame 8. A limiting pressure strip 85 is hinged to the upper end of the second movable swing rod 84. The movable bar frame 8 and the limiting pressure strip 85 are movablely connected through the second movable swing rod 84. The cold plate 4 is locked by the cooperation of the limiting pressure strip 85 and the cold plate 4, and it is fixed on the liquid cooling pipe 13. That is, at this time, the limiting pressure strip 85 presses on the cooperating guide strip 42.

[0048] An auxiliary support bar 71 is welded and fixed on the movable support platform 7 by welding process. The auxiliary support bar 71 provides auxiliary support for the cold plate 4 to ensure its installation stability. At this time, the auxiliary support bar 71 is inserted into the support mating cavity 43 and contacts the inner wall of the support mating cavity 43. In this way, the auxiliary support bar 71 and the support mating cavity 43 can provide further support for the cold plate 4.

[0049] An active channel 72 is provided on the auxiliary support bar 71. A limiting pressure bar 85 is inserted into the active channel 72. The limiting pressure bar 85 contacts the inner wall of the active channel 72. The limiting pressure bar 85 plays a supporting and guiding role through the cooperation between the limiting pressure bar 85 and the active channel 72. An assembly cavity 73 is also provided on the auxiliary support bar 71. A hollow sleeve 74 is welded and fixed in the assembly cavity 73 by welding process. In addition, an installation guide block 77 is symmetrically welded and fixed on the outside of the auxiliary support bar 71 by welding process. A limiting guide hole 78 is provided on the installation guide block 77.

[0050] The movable support frame 8 is installed on the auxiliary support frame 71, and the movable support frame 8 locks the movable platform 7. Specifically, the lower end of the movable support frame 8 is welded to a frame support rod 81, and the lower end of the frame support rod 81 is welded to an inner sleeve block 82, which is inserted into the hollow sleeve 74. Auxiliary limiting rods 83 are also symmetrically welded to the movable support frame 8, and are inserted into limiting guide holes 78. The cooperation between the auxiliary limiting rods 83 and the limiting guide holes 78 guides and limits the movement of the movable support frame 8. The auxiliary limiting rod 83 can only move up and down along the limiting guide hole 78. The auxiliary limiting rod 83 and the limiting guide hole 78 cooperate to movably install the movable strip 8 on the auxiliary support strip 71. In addition, when the limiting pressure strip 85 locks the cold plate 4, the auxiliary limiting rod 83 on the movable strip 8 is inserted into the auxiliary insertion hole 191 on the limiting support 19. The auxiliary insertion hole 191 and the auxiliary limiting rod 83 cooperate to further lock the movable support 7, thereby further locking the auxiliary support strip 71 to ensure its reliability and thus ensure the firmness of the cold plate 4 installation.

[0051] like Figure 17 As shown, an integrated liquid cooling heat dissipation device control system includes a central controller module, a communication module, an adjustment module, and a control module. The central controller module issues commands to the adjustment module and the control module through the communication module. The adjustment module adjusts the coolant flow rate, and the control module controls the operation of the circulating pump 2 and the heat exchanger 3.

[0052] The connection between two liquid cooling pipes 13 in a set is achieved by the cold plate 4, thereby enabling the first liquid cooling pipe 11 to form a closed circulation pipeline to circulate and transport the coolant. One cold plate 4 corresponds to one server and comes into contact with the server's heat source to dissipate heat from the server.

[0053] During the installation of the cold plate 4, align the guide cavity 44 on the cold plate 4 with the guide indicator rod 181, and then move the cold plate 4 downwards along the guide indicator rod 181. The guide indicator rod 181 guides the cold plate 4. As the cold plate 4 slowly moves downwards, the inclined protrusion 45 on the cold plate 4 will come into contact with the anti-shifting strip 6. Under the action of the inclined surface on the inclined protrusion 45, the anti-shifting strip 6 will be pushed to move, thereby causing the anti-shifting block 61 on the anti-shifting strip 6 to move until the top of the anti-shifting strip 6 passes over the inclined surface on the inclined protrusion 45, so that the anti-shifting block 61 is no longer supported on the underside of the protruding wing plate 58, thereby making the connecting pipe ring 5 unlocked.

[0054] When the connecting pipe ring 5 is in the unlocked state, as the cold plate 4 continues to move downward, the mating tube 41 on the cold plate 4 will be inserted into the sealing cavity 51 until it contacts the bottom of the sealing cavity 51. Then, as the cold plate 4 continues to move downward, it will drive the connecting pipe ring 5 to move downward together. As the connecting pipe ring 5 moves downward, it will also drive the sealing cap 54 to move downward, thereby causing the sealing cap 54 to exit the sealing groove 17 and enter the liquid cooling branch pipe 13. This will allow the connecting pipe head 14 to be in the open state, realizing the connection between the cold plate 4 and the liquid cooling branch pipe 13.

[0055] As the connecting ring 5 moves downward, the first movable rocker arm 59 will drive the movable support 7 to move towards the cold plate 4. As the movable support 7 moves, the limiting pressure strip 85 on the auxiliary support bar 71 will come into contact with the inner wall of the support mating cavity 43. Under the restriction of the inner wall of the support mating cavity 43, the limiting pressure strip 85 will not be able to move synchronously with the auxiliary support bar 71. This will cause relative movement between the limiting pressure strip 85 and the auxiliary support bar 71. Under the action of the second movable rocker arm 84, the movable bar frame 8 will move upward. As the movable bar frame 8 moves upward, it will also drive the inner plug block 82 to move upward. As the inner plug block 82 moves upward, a negative pressure will be generated in the hollow sleeve 74. As the movable bar frame 8 moves upward, it will also drive the auxiliary limiting rod 83 on the movable bar frame 8 to move upward, so that it moves completely above the limiting support 19.

[0056] Furthermore, as the cold plate 4 continues to move downwards, the connecting ring 5 will also continue to move downwards. This will allow the auxiliary support strip 71 to be inserted into the support mating cavity 43 and contact the inner wall of the support mating cavity 43. Thus, the auxiliary support strip 71, in cooperation with the support mating cavity 43, will further support the cold plate 4, ensuring its installation stability. At this time, the limiting pressure strip 85 is also above the mating guide strip 42, and the auxiliary limiting rod 83 is above the auxiliary insertion hole 191 and aligned with it. The limiting pressure strip 85 is now unrestricted, which also unrestrains the movable strip frame 8. Under the combined effect of the weight of the frame 8 and the negative pressure inside the hollow sleeve 74, the movable frame 8 will move downwards. In turn, under the action of the second movable swing rod 84, the limiting pressure strip 85 will move, causing the limiting pressure strip 85 to press against the mating guide strip 42. The limiting pressure strip 85 locks the cold plate 4. As the movable frame 8 moves downwards, the auxiliary limiting rod 83 on the movable frame 8 will be inserted into the auxiliary insertion hole 191. In this way, the movable support platform 7 can be locked with the cooperation of the auxiliary limiting rod 83 and the auxiliary insertion hole 191, further ensuring the stability of the movable support platform 7, and thus ensuring the stable installation of the cold plate 4.

[0057] When it is necessary to disassemble a certain cold plate 4, at the same time, pull the limiting pressure strips 85 on both sides of the cold plate 4 to make it no longer lock the cold plate 4. Then, under the action of the first spring 57, the cold plate 4 can be moved upward slightly, so that the limiting pressure strips 85 contact the inner wall of the support mating cavity 43 again. Then, the limiting pressure strips 85 can be released to quickly remove the cold plate 4 from the liquid cooling pipe 13. The operation is simple, convenient and quick.

[0058] In actual use, the cold plate 4 can be added or removed according to the increase or decrease of servers, making it highly adaptable. When the cold plate 4 is not installed on the liquid cooling pipe 13, the connecting pipe head 14 can be sealed by the sealing cap 54 to prevent the coolant from overflowing, and the cold plate 4 can be installed and removed conveniently and quickly.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
