Description

Technical Field

[0001] The present application belongs to the technical field of computer internal auxiliary equipment, and in particular, relates to a diverter and a multi-graphics card water cooling device. Background Art

[0002] In desktop computers (computers) currently on the market, as the performance of CPUs, graphics cards, etc. improves, the heat generated during operation is also increasing. A common heat dissipation solution is to set up a cooling fan or a water cooling system for heat dissipation. However, in host applications with multiple graphics card arrays, such as server hosts for AI deep learning, such hosts use 4-way or 8-way graphics cards for array use. Because these multiple graphics cards are arrayed together, heat is more likely to accumulate and rise quickly, so the stability of these multiple graphics cards running simultaneously is low.

[0003] In the prior art, the heat dissipation solution for multi-graphics card array applications is to set a water cooling plate on each graphics card and use a cooling water circulation system to cool down multiple graphics cards simultaneously. This cooling water circulation system generally supplies water to each water cooling plate through a water supply part, and then a diversion mechanism is set between the water supply part and each water cooling plate to divert the cooling water to each water cooling plate.

[0004] The traditional diversion mechanism has a simple structure, including a water inlet and multiple water outlets, and directly diverts the water to the multiple water outlets through the one water inlet. In actual applications, it is found that due to the influence of distance, among the multiple water outlets, the water outlets that are closer to the water inlet have a higher output water pressure, while the water outlets that are farther away from the water inlet have a lower output water pressure, so that the water pressure output from different water outlets on the diversion mechanism is uneven, resulting in that in the array of multiple graphics cards, the water cooling plates on some graphics cards have a good cooling effect, while the water cooling plates on other graphics cards have a poor cooling effect, which ultimately affects the overall heat dissipation effect. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a diverter and a multi-graphics card water cooling device to solve the technical problem of uneven water distribution pressure in the diverter mechanism used for water cooling in the prior art.

[0006] To achieve the above purpose, the technical solution adopted in the present application is: to provide a diverter for use in a water-cooled heat dissipation device, the diverter comprising:

[0007] The flow dividing body is provided with a partition plate and a water inlet for connecting with a pipeline, wherein the partition plate divides the interior of the flow dividing body into a first chamber and a second chamber; the partition plate is provided with a first flow dividing groove and a plurality of second flow dividing grooves on the plate surface located in the first chamber, and the partition plate is provided with a plurality of third flow dividing grooves on the plate surface located in the second chamber; wherein the number of the second flow dividing grooves is twice that of the first flow dividing grooves, and the number of the third flow dividing grooves is twice that of the second flow dividing grooves;

[0008] The first diverter groove is connected to the water inlet, and both ends of the first diverter groove are respectively connected to one of the second diverter grooves; and both ends of the second diverter groove are respectively connected to one of the third diverter grooves;

[0009] A surface cover is arranged in the second chamber, and a plurality of water holes are opened on the surface cover, and two ends of each of the third diversion grooves are respectively connected to one of the water holes.

[0010] The beneficial effect of the diverter provided by the present application is that: compared with the prior art, the diverter of the present application adopts a multi-stage diverter slot structure, and each diverter slot adopts a two-end diverter structure to reduce the influence of distance, so that the water pressure in each stage of the diverter slot is kept uniformly output, so that the water pressure at each stage in the entire diversion process is uniform, so that the water pressure output from each water hole is uniform in the end, and the uniformity of the output water pressure is effectively ensured. In addition, compared with the diversion mechanism in the prior art that uses multiple diverters to be stacked and connected in sequence, the diverter of the present application is respectively provided with multi-stage diverter slots on the two end plates of the partition plate, and the diversion is performed in multiple increments through these diverter slots, which effectively reduces the occupied space and is conducive to reducing the overall volume.

[0012] The structure of the second flow diverter is improved, and the second flow diverter includes multiple layers of diverter grooves with increasing multiples, and the two ends of each diverter groove in the upper layer are respectively connected to a diverter groove in the lower layer, and the number of diverter grooves in the lower layer is twice the number of diverter grooves in the adjacent upper layer.

The surface cover is a long strip plate. The multiple water holes are opened on the surface cover at intervals along the length direction of the surface cover. Each water hole corresponds to the end position of each third diverter slot. This is conducive to matching the array layout of the water cooling plate, so that each water hole can be connected to the joint on the water cooling plate at the corresponding position, thereby improving the coverage and mutual matching of the diverter.

[0014] In one embodiment, the first chamber further comprises a flow channel arranged to avoid the first diverter slot and the second diverter slot, one end of the flow channel is connected to the water inlet, and the other end of the flow channel is connected to the center point of the first diverter slot. In this way, the water inlet is connected to the first diverter slot by the flow channel. Compared with the structure in which the water inlet interface of the traditional diverter can only be arranged in the center, the water inlet on the diverter body of the present application is not restricted in the setting position, and the water inlet can be arranged on any side of the diverter body.

[0015] In one embodiment, the flow divider further comprises a back cover that matches the shape of the flow divider body, the back cover covers the first chamber, and covers the first flow divider slot and the plurality of second flow divider slots.

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0044] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0045] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0046] Traditional shunt structures, such as Figure 1 As shown, it includes a water inlet X and multiple water outlets Y, and the multiple water outlets Y are arranged in a row through a straight flow channel. When diverting, the water enters the straight flow channel from the water inlet X and is directly output from each water outlet Y, and is sequentially stacked and connected through multiple diverters to form a multi-stage diverting mechanism.

[0047] In actual applications, it is found that due to the influence of distance, among the multiple water outlets Y, the water outlet Y that is shorter than the water inlet X has a larger output water pressure, and the water outlet Y that is farther away from the water inlet X has a smaller output water pressure, so that the water pressure output from different water outlets Y on the diverter is uneven, resulting in that in the array of multiple graphics cards, the water cooling plates on some graphics cards have a good cooling effect, while the water cooling plates on other graphics cards have a poor cooling effect, which ultimately affects the overall heat dissipation effect.

[0048] In addition, since multiple diverters need to be stacked and connected in sequence to form a multi-level diversion mechanism, the entire diversion mechanism is large in size, occupies a lot of space, and has certain requirements on the volume of the server main chassis.

[0049] Here, the embodiments of the present application provide a new type of diverter and multi-graphics card water cooling device, which can perform multi-stage diversion of water to make the diverted water pressure uniform, effectively solving the technical problem of uneven water diversion pressure in traditional diversion mechanisms used for water cooling, and are now described in detail.

[0050] Please also read Figure 2 , Figure 3 and Figure 4 The diverter is used in combination with a water-cooling heat dissipation device, and the diverter at least includes a diverter body 1 and a surface cover 2.

[0051] The flow dividing body 1 can be understood as a container that can pass water. The flow dividing body 1 is provided with a partition plate 11 and a water inlet 12. The water inlet 12 is used to connect to an access pipe, such as a water pipe connected to a water pump.

[0052] like Figure 3 and Figure 4 As shown, the partition plate 11 is disposed inside the flow dividing body 1 and divides the inside of the flow dividing body 1 into a first chamber 13 and a second chamber 14. It can be understood here that at the two opposite end surfaces of the partition plate 11, one end surface is located in the first chamber 13, and the other end surface is located in the second chamber 14.

[0053] A first diverter slot 3 and a plurality of second diverter slots 4 are provided on the plate surface of the partition plate 11 located in the first chamber 13, and a plurality of third diverter slots 5 are provided on the plate surface of the partition plate 11 located in the second chamber 14. The number of the second diverter slots 4 is twice that of the first diverter slots 3, and the number of the third diverter slots 5 is twice that of the second diverter slots 4, thereby forming a diverter layout with increasing multiples.

[0054] The first diverter trough 3 is connected to the water inlet 12, and the two ends of the first diverter trough 3 are respectively connected to a second diverter trough 4. The two ends of the second diverter trough 4 are respectively connected to a third diverter trough 5. In this embodiment, these diverter troughs are all linear troughs, and the two ends of the upper level trough body are respectively connected to the middle part of the lower level trough body through the middle flow channel.

[0055] The surface cover 2 is used to connect to a target carrier such as a water cooling plate, etc. The surface cover 2 is disposed in the second chamber 14 . A plurality of water holes 21 are provided on the surface cover 2 . Both ends of each third diversion slot 5 are connected to a water hole 21 .

[0056] like Figure 3 As shown, the first diverter trough 3 and each second diverter trough 4 are located at different heights inside the diverter body 1. In this embodiment, the first diverter trough 3 is located at a higher height than each second diverter trough 4, and each second diverter trough 4 is located at the same height. The water flowing from the water inlet 12 to the first diverter trough 3 flows from both ends of the first diverter trough 3 to the second diverter troughs 4 connected to each other; then, the water flows from both ends of each second diverter trough 4 to the third diverter trough 5 connected to each other; finally, the water is discharged from both ends of each third diverter trough 5 through the corresponding water holes 21 to achieve uniform diversion.

[0057] It should be noted that the water inlet 12 can be used as a water inlet interface or a water outlet interface. Similarly, the water hole 21 can also be used as a water inlet hole or a water outlet hole. The diverter provided in the embodiment of the present application can be used as a diversion of the inlet water or as a confluence of the outlet water according to the location of the diverter in the water circulation system. Therefore, the flow direction of the fluid inside the diverter is not specifically limited here.

[0058] Compared with the prior art, the diverter provided in the embodiment of the present application adopts a multi-stage diverter slot structure, in which the first diverter slot 3 performs a primary diversion at both ends, and then a secondary diversion is performed through the second diverter slot 4, and each second diverter slot 4 further diverts the water at both ends; then, a third diversion slot 5 performs a third diversion, and each third diversion slot 5 further diverts the water at both ends and outputs it from each water through hole 21.

[0059] It can be seen that each diversion slot adopts a structure of diversion at both ends to reduce the influence of distance, and the water pressure in each diversion slot is kept uniformly output, so that the water pressure at each level in the whole diversion process is uniform, so that the water pressure output from each water hole 21 is uniform and unified.

[0060] In addition, compared with the above-mentioned traditional diverter, which adopts a diversion mechanism composed of multiple diverters stacked and connected in sequence, the diverter provided in the embodiment of the present application is respectively provided with multi-level diversion grooves on the two end plate surfaces of the partition plate 11, and the diversion is performed in multiples through these diversion grooves, which effectively reduces the occupied space and is conducive to reducing the overall volume.

[0061] Preferably, in the embodiments of the present application, please refer to Figure 3 and Figure 4 The end of the first diverter slot 3 is connected to the center point of the second diverter slot 4. The end of the second diverter slot 4 is connected to the center point of the third diverter slot 5.

[0062] In this way, each diversion slot of the previous level is connected to the center point of each diversion slot of the next level, so that the water in each diversion slot on each level is evenly distributed, thereby making the water pressure in each diversion part in the entire diversion process uniform, effectively eliminating the influence of distance, making the final output water pressure uniform, and further improving the uniformity of the output water pressure.

[0063] In another embodiment of the present application, the flow splitter in the above embodiment has a 1-input and 8-output structure. In order to increase the flow splitting amount of the flow splitter, the structure of the second flow splitter 4 in the flow splitter may be further improved.

[0064] Please also read Figure 3 and Figure 5 The second diverter slot 4 also includes a plurality of diverter slots 41 with increasing multiples, and both ends of each diverter slot 41a of the upper layer are respectively connected to a diverter slot 41b of the lower layer, and the number of the diverter slots 41b of the lower layer is twice the number of the adjacent diverter slots 41a of the upper layer.

[0065] Thus, in the layout of the second shunt slot 4, the number of each shunt slot 41 is set in increasing multiples and in layers. The shunt slots 41 on different levels are set at different heights in the shunt body 1. The shunt slots 41 on the same level are arranged side by side, and both ends of each shunt slot 41a on the upper level are respectively connected to a shunt slot 41b on the lower level, and the number of each third shunt slot 5 is matched therewith, so that the multiples of the shunt output are increased, thereby increasing the shunt flow rate of the entire shunt.

[0066] As an example, Figure 5 As shown, it is a 1-in 16-out structure, wherein the second diverter slot 4 includes two layers of diverter slots 41 located at different heights, and the number of diverter slots 41b in the lower layer is twice the number of diverter slots 41a in the upper layer. In this embodiment, there are two diverter slots 41a in the upper layer and four diverter slots 41b in the lower layer. The diverter slots 41 on the same layer have the same shape, are arranged side by side and spaced apart, and form a trapezoidal array. The number of each third diverter slot 5 on the other end plate surface of the partition plate 11 matches it, so that the two ends of each lower diverter slot 41b are connected to a third diverter slot 5 respectively, and then output through the water holes 21 at the corresponding positions on the two ends of each third diverter slot 5.

[0067] In this way, the flow volume of the entire flow divider can be increased by arranging and arranging the second flow divider slots 4 in multiple increments.

[0068] In the embodiments of this application, please refer to Figure 3 and Figure 4 The flow dividing body 1 is a long strip container, and the first flow dividing groove 3, the second flow dividing groove 4 and the third flow dividing groove 5 are arranged on the plate surface of the partition plate 11 at intervals along the length direction of the flow dividing body 1. In this way, the space on the flow dividing body 1 is utilized to the maximum extent, and the internal space utilization rate of the flow dividing body 1 is effectively improved.

[0069] The surface cover 2 is preferably a long strip, and a plurality of water holes 21 are provided on the surface cover 2 at intervals along the length direction of the surface cover 2, and each water hole 21 on the surface cover 2 corresponds to the end position of each third diversion slot 5. This is conducive to matching the array layout of the water cooling plate, so that each water hole 21 can be connected to the joint on the corresponding position of the water cooling plate.

[0070] In actual applications, multiple graphics cards are plugged into the slots of the computer motherboard, so that the graphics cards are arranged side by side to form an array, and a water cooling plate is arranged on each graphics card, and the joints on each water cooling plate extend out on the same side. In the diverter of the present application, the diverter body 1 is a long strip container, and is combined with each water hole 21 on the cover 2, so that each water hole 21 can be smoothly connected to the joints on each water cooling plate, thereby improving the coverage and mutual coordination of the diverter.

[0071] In the embodiments of this application, please refer to Figure 3 and Figure 5 A flow channel 15 is also provided in the first chamber 13 of the flow dividing body 1 . The flow channel 15 is arranged to avoid the first flow dividing groove 3 and the second flow dividing groove 4 in the first chamber 13 , so as to maximize the use of the internal space of the flow dividing body 1 .

[0072] One end of the flow channel 15 is connected to the water receiving port 12 on the diversion body 1 , and the other end of the flow channel 15 is connected to the center point of the first diversion slot 3 .

[0073] As an example, when the water inlet 12 is used as a water inlet interface, water enters the first chamber 13 of the diversion body 1 from the water inlet 12 and reaches the first diversion groove 3 along the flow channel 15 for primary diversion.

[0074] Compared with the traditional diverter structure, the water inlet X on the traditional diverter can only be set in the center of the diverter. In the diverter of the present application, the water inlet 12 is connected to the first diverter slot 3 by the flow channel 15, so that the setting position of the water inlet 12 on the diverter body 1 is not restricted, and the water inlet 12 can be set on any side of the diverter body 1.

[0075] In one embodiment of the present application, see Figure 3 The flow divider also includes a back cover 6 that matches the shape of the flow divider body 1. The back cover 6 covers the first chamber 13 and covers the first flow divider slot 3 and the plurality of second flow divider slots 4. This is beneficial for processing the internal structure of the flow divider body 1 during the production process, such as opening the slot body and the flow channel 15, and then sealing the interior of the flow divider body 1 by installing the back cover 6, which effectively reduces the processing difficulty and ensures the sealing of each flow divider slot and flow channel inside the flow divider body 1.

[0076] In this embodiment, the front cover 2 and the back cover 6 can be installed in the second chamber 14 and the first chamber 13 by welding, thereby ensuring the sealing.

[0077] Please also read Figure 6 , Figure 7 and Figure 8 The present application also provides a multi-graphics card water-cooling device, including a radiator 7, a water pump 8, a plurality of water-cooling plates 9 and the diverter 100 of the present application.

[0078] In this embodiment, a plurality of graphics cards 200 are respectively plugged into a computer motherboard 300, and the plurality of water cooling plates 9 are respectively arranged on the graphics cards 200. Figure 8 As shown, a water inlet joint 91 and a water outlet joint 92 are provided on the same side of each water cooling plate 9 , and the water inlet joint 91 and the water outlet joint 92 are in communication with the internal flow channel of the water cooling plate 9 .

[0079] Two flow dividers 100 are provided. One flow divider 100 a is used as an input flow divider mechanism for inputting cooling liquid into each water-cooling plate 9 , and the water holes 21 thereon are respectively connected to the water inlet joints 91 on each water-cooling plate 9 .

[0080] Another flow divider 100 b is used as an output confluence mechanism for outputting cooling liquid to each water-cooling plate 9 , and the water holes 21 thereon are respectively connected to the water outlet joints 92 on each water-cooling plate 9 .

[0081] In this embodiment, if Figure 6 and Fig. 9 As shown, an arrow mark M may preferably be provided on the flow divider 100 to distinguish the flow direction.

[0082] In this embodiment, if Figure 7 As shown, the radiator 7 includes a heat dissipation water row 71 and a heat dissipation fan 72. The heat dissipation fan 72 is arranged on the heat dissipation water row 71. The heat dissipation fan 72 blows away the heat on the heat dissipation water row 71 to achieve a heat dissipation effect. The heat dissipation water row 71 is provided with a water inlet connection end 711 and a water outlet connection end 712. The water inlet connection end 711 and the water outlet connection end 712 are respectively connected to the water pump 8 through pipelines.

[0083] The water pump 8 is connected between the radiator 7 and the two diverters 100 through a pipeline, so that the entire multi-graphics card 200 water-cooling heat dissipation device forms a water-cooling circulation heat dissipation system to cool the multiple graphics cards 200 synchronously.

[0084] In this way, the water pump 8 supplies cooling water to each water cooling plate 9 through a diverter 100, and the water cooling plate 9 absorbs the heat of the graphics card 200 through the cooling water; then, the dispersed water is concentrated through another diverter 100, and then guided to the radiator 7 through a pipe for discharge, forming a cycle, effectively ensuring the heat dissipation effect.

[0085] For the connection structure between the diverter 100 and the water cooling plate 9, in one embodiment of the present application, please refer to Figure 8 and Fig. 9 The diverter body 1 of the diverter 100 is also provided with a mounting plate 16 , on which a plurality of connecting ears 161 are provided respectively cooperating with the positions of the water holes 21 , and each connecting ear 161 is provided with a connecting hole 162 .

[0086] The water outlet joint 92 and the water inlet joint 91 of the water cooling plate 9 are both provided with mounting holes 93 corresponding to the positions of the above-mentioned connecting holes 162 so as to install fasteners such as screws for penetration and fixing.

[0087] In this embodiment, each connection ear 161 is arranged on the same side of the mounting plate 16 and extends in parallel in the same direction. When the water holes 21 on the diverter 100 are synchronously plugged into the outlet joints 92 or the inlet joints 91 on each water cooling plate 9, the connection ear 161 extends to the surface of the outlet joint 92 or the inlet joint 91, so that the connection hole 162 on the connection ear 161 corresponds to the position of the mounting hole 93 on the outlet joint 92 or the inlet joint 91, realizing automatic alignment and facilitating the direct connection and fixation of fasteners such as screws. It can be seen that the structure of the screw installation and fixation is simple, easy to assemble and disassemble, and convenient for daily maintenance.

[0088] Preferably, in the embodiments of the present application, please refer to Fig. 9 A sealing ring 94 is also provided on the water inlet joint 91 and the water outlet joint 92 of each water cooling plate 9 to ensure the sealing effect.
