Description

Technical Field

[0001] The utility model relates to the technical field of immersion heat dissipation, in particular to a liquid inlet flow distribution device and an immersion cooling system thereof which can enable cooling liquid to flow into a location adjacent to a heating component appropriately. Background Art

[0002] Generally speaking, an immersion water tank is usually used in an immersion cooling system, which achieves the cooling effect by completely or partially immersing the device to be cooled in an immersion water tank filled with coolant, and circulating the coolant in the water tank to remove the waste heat of the device to be cooled. Specifically, the immersion water tank is filled with coolant (usually water or a special coolant selected according to actual needs), and the device to be cooled, such as a high-power electronic device, a generator set, etc., can be completely or partially immersed in the coolant in the water tank, so that the heat of the device to be cooled can be more effectively discharged into the coolant, thereby effectively improving the cooling efficiency.

[0003] However, in the current immersion cooling water tanks installed with servers, the coolant mostly flows directly into the accommodation space. Since the immersion cooling system has multiple server slots, when the server is not fully inserted and there is idle space, some coolant will easily flow from the unobstructed idle space, making it difficult for the coolant to enter the server, thereby causing poor cooling effect of the server; or, when the server is fully inserted, the space between the servers is too small, which increases the resistance of the coolant flow, also resulting in poor cooling effect of the server.

[0039] See also Figure 1, which is a schematic diagram of a first embodiment of a liquid inlet flow diversion device of the present invention. The liquid inlet flow diversion device 1 of the present invention is applied to an immersion water tank 50 of an immersion cooling system 4 .

[0040] As shown in the figure, the liquid inlet diversion device 1 of the utility model comprises a liquid inlet pipe body 10 and a plurality of diversion pipes 20. The liquid inlet pipe body 10 is arranged in the submerged water tank 50 along the depth direction Z of the submerged water tank 50. The liquid inlet pipe body 10 has a liquid inlet joint 11 and a plurality of liquid outlet joints 12. One end of each of the diversion pipes 20 is connected to each of the liquid outlet joints 12, and the other end of at least a portion of the diversion pipes 20 is located adjacent to the heating component 91. That is, the other end of some of the diversion pipes 20 can directly output the cooling liquid to the submerged water tank 50, while the other end of some of the diversion pipes 20 outputs the cooling liquid corresponding to the heating component 91. The heating components 91 corresponding to the other ends of the multiple diversion pipes 20 are partially the same or all different. That is, the diversion pipes 20 corresponding to the heating component 91 that output the cooling liquid can be partially outputting the cooling liquid to the same heating component 91, or respectively outputting the cooling liquid to different heating components 91.

[0041] In the present embodiment, the liquid inlet tube body 10 is a straight tube structure. The liquid inlet joint 11 is located at one end of the liquid inlet tube body 10 away from the bottom surface of the immersion water tank 50. The multiple liquid outlet joints 12 are arranged at intervals on one side or two opposite sides of the liquid inlet tube body 10 along the depth direction Z. For example, the multiple liquid outlet joints 12 can be arranged at intervals on the same side of the liquid inlet tube body 10; or, the multiple liquid outlet joints 12 can be symmetrically and spaced apart on the opposite sides of the liquid inlet tube body 10; or, the multiple liquid outlet joints 12 can be arranged on the opposite sides of the liquid inlet tube body 10 in a staggered manner corresponding to the opposite sides of the liquid inlet tube body 10.

[0042] Optionally, the other end of the shunt pipe 20 may be adjacent to the heat generating component 91 or directly facing the heat generating component 91 , so that the coolant impacts the surface of the heat generating component 91 to dissipate heat and then flows into the space of the immersion water tank 50 .

[0043] See also Figure 2 , which is a schematic diagram of a second embodiment of the liquid inlet diversion device of the utility model. In this embodiment, the components with the same component symbols have the same or similar configurations and operations as the above-mentioned embodiments, and the same or similar parts will not be repeated here.

[0044] As shown in the figure, the main difference between this embodiment and the aforementioned embodiment is that the liquid inlet pipe body 10 is an L-shaped tubular structure to form a vertical pipe portion 13 and a horizontal pipe portion 14 .

[0045] The liquid inlet joint 11 is located at one end of the vertical tube portion 13 away from the bottom surface of the immersion water tank 50. The multiple liquid outlet joints 12 are arranged at intervals on one side or two opposite sides of the transverse tube portion 14 along the axial direction of the transverse tube portion 14. For example, the multiple liquid outlet joints 12 can be arranged at intervals on the same side of the transverse tube portion 14; or, the multiple liquid outlet joints 12 can be symmetrically and spaced apart on the opposite sides of the transverse tube portion 14; or, the multiple liquid outlet joints 12 can be arranged at the opposite sides of the transverse tube portion 14 in a staggered manner corresponding to the opposite sides of the transverse tube portion 14.

[0046] See also Figures 3 to 5 , which is a schematic diagram of a water cooling plate of a second embodiment of the liquid inlet diversion device of the utility model. In this embodiment, the components with the same component symbols have the same or similar configurations and operations as those of the aforementioned embodiments, and the same or similar parts will not be repeated here.

[0047] As shown in the figure, in this embodiment, the main difference from the above-mentioned embodiments is that the liquid inlet flow dividing device 1 comprises a plurality of water cooling plates 30. That is to say, the water cooling plates 30 in this embodiment can be applied to any of the above-mentioned embodiments.

[0048] Further, the plurality of water-cooling plates 30 correspond to a portion of the shunt pipes 20 and are disposed at the other end of each of the shunt pipes 20 in the portion of the shunt pipes 20. The water-cooling plate 30 comprises a water-cooling plate body 31, a plurality of support members 32 and a connection joint 33. The plurality of support members 32 are respectively disposed at intervals on one side of the water-cooling plate body 31, and a gap is formed between each of the support members 32. The connection joint 33 is used to connect the other end of the shunt pipe 20, which is disposed on the water-cooling plate body 31 and opposite to the plurality of support members 32, and has a liquid outlet 34 that penetrates the water-cooling plate body 31.

[0049] The plurality of support members 32 are configured to fix the water-cooled plate 30 above or on one side of the heat-generating component 91. That is, the plurality of support members 32 are used to fix the water-cooled plate 30 above or on one side of the heat-generating component 91, and each of the support members 32 is used to make the liquid outlet 34 and the heat-generating component 91 have a certain interval, so that the water-cooled plate body 31 and the plurality of support members 32 form a space; the space and the gap formed between each of the support members 32 are interconnected, thereby forming an open pipeline design, so that the coolant output through the shunt pipe 20 and the liquid outlet 34 can directly flow into the immersion water tank 50.

[0050] Incidentally, the plurality of support members 32 include at least two support members 32 for firmness considerations, but are not limited thereto, and at least two or more support members 32 may be provided as required. The support member 32 is fixed above the heat generating component 91, and the fixing method thereof may be, for example: a screw hole is provided at the bottom of the plurality of support members 32, and the screw is locked through a through hole on the circuit board carrying the heat generating component 91; or, through a combination of a rivet and an elastic member, one end of which is snapped into the through hole on the circuit board, and the other end is buckled against one end of the support member 32 or passes through the water cooling plate body 31 and buckles against a side of the water cooling plate body 31 provided with the connecting joint 33, thereby fixing the support member 32 on the circuit board; or, a general adhesive or a heat conductive adhesive is provided at the bottom of the plurality of support members 32 to fix them on the circuit board. The above fixing methods are only examples and are not limited thereto.

[0051] When the water-cooled plate 30 is used for heat dissipation or cooling, the coolant output through the shunt pipe 20 passes through the liquid outlet 34 at a high flow rate, directly impacting the surface of the heat-generating component 91 for heat dissipation, and the coolant that absorbs the heat of the heat-generating component 91 flows directly into the immersion water tank 50 through the gaps formed between the support members 32, and mixes with the coolant originally in the immersion heat dissipation water tank.

[0052] In this embodiment, the above configuration can ensure that the coolant can stably impact the surface of the heat-generating component 91 and achieve the purpose of heat dissipation or cooling.

[0053] Please cooperate Figures 1 to 5 , and continue with Figure 6 , which is a block diagram of the immersion cooling system of the present invention.

[0054] As shown in the figure, the utility model provides an immersion cooling system 4 suitable for cooling a device to be cooled 9 , wherein the device to be cooled 9 has a plurality of heat generating components 91 .

[0055] The submerged water tank 50 has a housing space 51 for accommodating the device to be cooled 9, and the submerged water tank 50 is provided with a coolant inlet 52 and a coolant outlet 53 communicating with the housing space 51. The heat exchange row 60 is connected to the coolant inlet 52 and the coolant outlet 53 through a pipeline 70, and the pump 80 is connected between the coolant inlet 52 and the coolant outlet 53 through the pipeline 70. The liquid inlet diversion device 1 is arranged in the housing space 51, and its detailed structure and description are as described in the above embodiment, and will not be repeated here. Among them, the liquid inlet connector 11 is arranged corresponding to the coolant input port 52, and the pipeline 70 is connected to the liquid inlet connector 11. The coolant flows through the liquid inlet connector 11 through the pipeline 70, through the liquid inlet pipe body 10, and then flows to at least one liquid outlet connector 12, and directly flows to the accommodating space 51 through the shunt pipe 20, and flows to the accommodating space 51 through the shunt pipe 20 or through the shunt pipe 20 and the water cooling plate 30 after impacting the heat-generating component 91, so that the heat of the device to be cooled 9 in the accommodating space 51 is taken away by the coolant to achieve the cooling effect.

[0056] Incidentally, the device to be cooled 9 is, for example, a device that generates a large amount of heat during operation and requires a high-efficiency heat dissipation system to maintain its operation, for example, a high-power electronic device such as a server, a high-performance computer, a communication system, etc.

[0057] Furthermore, the heat exchange row 60 is connected between the coolant input port 52 (which is provided with the liquid inlet joint 11 of the liquid inlet pipe body 10 of the liquid inlet diversion device 1) and the coolant output port 53 through the pipeline 70, so as to dissipate the heat of the coolant. In addition, the pump 80 is also connected between the coolant input port 52 and the coolant output port 53 through the pipeline 70, so as to drive the coolant to flow. In other words, through the drive of the pump 80, the coolant can be transported to the liquid inlet diversion device 1 through the coolant input port 52, and connected to the diversion pipe 20 through the liquid outlet joint 12 of the liquid inlet diversion device 1 to be directly discharged to the accommodating space 51 and to the accommodating space 51 adjacent to the heat generating component 91. In addition, after absorbing the heat of the device to be cooled 9, it flows to the heat exchange row 60 through the coolant output port 53 via the pipeline 70 for cooling, and the above-mentioned coolant circulation is repeatedly performed, thereby achieving the cooling effect.

[0058] In summary, the liquid inlet flow diversion device and the immersion cooling system of the present invention can preferentially discharge the cooling liquid from the vicinity of or toward the heat generating component through the configuration of the liquid outlet joint and the diversion pipe, thereby making the cooling circulation in the immersion water tank more uniform and achieving the best cooling effect.
