Description

Technical Field

[0001] The present application relates to the technical field of flow through a server, and in particular to a server and a flow through component thereof. Background Art

[0002] The power supply of each node in the cabinet server is realized by the copper busbar, which is easy to generate heat during the process. At present, the heat dissipation of the copper busbar itself mainly relies on radiation or surface air convection, but there are problems of heat dissipation and temperature rise. The difficulty of heat dissipation of the copper busbar and the temperature rise are the key bottlenecks that restrict the further improvement of the copper busbar's flow capacity. Traditional technology improves the heat dissipation capacity of the copper busbar by increasing the size of the copper busbar and increasing the air volume on the surface of the copper busbar, but the heat dissipation efficiency is still low and the temperature rise of the copper busbar is still high. For example, in application scenarios with high power consumption, the temperature rise of the copper busbar is high, and the flow capacity of the smaller copper busbar is limited and cannot meet the large flow requirements. If a larger copper busbar is used to improve the flow capacity, the copper busbar will be large in size, heavy in weight, high in cost, and difficult to operate and maintain.

[0053] The terms "first", "second", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0054] Please refer to Figure 1 , Figure 1 1 is a schematic diagram of the structure of the cabinet server 1000 in the first embodiment of the present application. The cabinet server 1000 includes a server body 1120, a first flow member 1 and a first power supply 1400. The server body 1120 is electrically connected to the first flow member 1, and the first flow member 1 is used to transmit power to the server body 1120. Please refer to Figure 2 The first flow member 1 has a first cooling channel 10 therein, and the first cooling channel 10 is used to communicate with the first cooling device 1500 to dissipate heat for the first flow member 1. It can be understood that the cabinet server 1000 can be externally connected to the first cooling device 1500, or the cabinet server 1000 can include the first cooling device 1500, which is not limited here.

[0055] Specifically, the server body 1120 includes a cabinet 1100 and a plurality of server nodes 1200 ( Figure 1Only one server node 1200 is shown in the figure, and multiple server nodes 1200 can be installed in the actual cabinet 1100). Several server nodes 1200 are arranged along the height direction of the cabinet 1100 and installed in the cabinet 1100. A mainboard (not shown) is provided in each server node 1200. The mainboard of each server node 1200 has a positive pole (not shown) and a negative pole (not shown). The first flow member 1 includes a positive flow member 1310 and a negative flow member 1320. The positive flow member 1310 is used to connect the positive poles of several server nodes 1200 and the positive pole of the first power supply 1400, and the negative flow member 1320 is used to connect the negative poles in several server nodes 1200 and the negative pole of the first power supply 1400.

[0056] Thus, a first cooling channel 10 is formed inside the first flow member 1. The first flow member 1 is cooled in time by the circulation of the cooling fluid in the first cooling channel 10. The liquid cooling has high heat dissipation efficiency, and can quickly cool the first flow member 1, reduce temperature rise, and improve the flow capacity of the first flow member 1, thereby solving the problem of insufficient flow capacity of the first flow member 1 during high-power power supply, and meeting the high-power flow requirements. Moreover, since the first cooling channel 10 is formed inside the first flow member 1, the amount of material used can be reduced, and the production cost and operation and maintenance cost can be reduced.

[0057] In some embodiments, the first flow member 1 is a flow bar applied to a 48V power supply network. In other embodiments, the first flow member 1 can be applied to power supply networks of other voltages, which is not limited here.

[0058] In some embodiments, the material of the first flow member 1 is copper alloy or copper bar, etc. In other embodiments, the material of the first flow member 1 can be other metal alloys with excellent electrical conductivity such as aluminum bar, etc., which is not limited here.

[0059] In some embodiments, the first flow member 1 is in a rectangular parallelepiped shape. It is understandable that in other embodiments, the first flow member 1 can be made into any suitable shape based on actual product needs, such as a cylinder, etc., which is not limited here.

[0060] In some embodiments, the first cooling channel 10 is U-shaped. It is understandable that in other embodiments, the first cooling channel 10 may be in a straight line shape, an S shape, an M shape, or a spiral shape, etc., which is not limited here.

[0061] Therefore, in the embodiment of the present application, the first cooling channels 10 of different shapes have different liquid cooling capabilities. The first cooling channels 10 can be of any shape, can match liquid cooling in different working scenarios, and enrich the liquid cooling scenarios.

[0062] In some embodiments, for a cabinet server 1000 with a power of 30,000-50,000 watts, the inner diameter of the first cooling channel 10 of the first flow member 1 is 3-5 mm, the outer diameter width (dimension in the X-axis direction) of the first flow member 1 is 8-10 mm, and the outer diameter depth (dimension in the Y-axis direction) is 20-30 mm; for a cabinet server 1000 with a power of more than 50,000 watts, the inner diameter of the first cooling channel 10 of the first flow member 1 is 5-10 mm, the outer diameter width of the first flow member 1 is 12-15 mm, and the outer diameter depth is 30-40 mm. It can be understood that the above dimensions of the inner diameter and outer diameter of the first flow member 1 are only examples. In actual applications, the dimensions of the inner diameter and outer diameter of the first flow member 1 can also be adaptively adjusted according to the needs of the flow capacity, and are not limited here.

[0063] In some embodiments, the cooling fluid may be an insulating cooling fluid, such as silicon mineral oil or electronic fluorinated liquid, etc., wherein the cooling fluid in this embodiment is electronic fluorinated liquid.

[0064] In some embodiments, the inner wall of the first cooling channel 10 may be provided with an insulating coating or insulating material to achieve electrical insulation of the first cooling channel 10, and the cooling fluid may be a non-electrically insulating cooling fluid such as water.

[0065] For some examples, please refer to Figure 3 The first cooling channel 10 includes a liquid inlet 1012 and a liquid outlet 1022. The liquid inlet 1012 is used to introduce the cooling liquid, and the liquid outlet 1022 is used to lead out the cooling liquid.

[0066] In some embodiments, the liquid inlet 1012 and the liquid outlet 1022 may be located on the same side of the first flow member 1. In other embodiments, the liquid inlet 1012 and the liquid outlet 1022 may be located on opposite sides of the first flow member 1. Thus, one of them may be selected according to actual layout requirements.

[0067] In some embodiments, the cabinet server 1000 further includes a liquid inlet connector 1600 and a liquid outlet connector 1700 , wherein the liquid inlet connector 1600 is connected between the liquid inlet 1012 and the first cooling device 1500 , and the liquid outlet connector 1700 is connected between the liquid outlet 1022 and the first cooling device 1500 .

[0068] Therefore, in the embodiment of the present application, the first cooling channel 10 and the first cooling device 1500 are connected via the liquid inlet joint 1600 and the liquid outlet joint 1700 .

[0069] For some examples, please refer to Figure 2The first cooling device 1500 includes a liquid inlet channel 1501, a liquid outlet channel 1502 and a cooling module 1503. The liquid inlet channel 1501 is a liquid inlet channel for a single server, the liquid outlet channel 1502 is a liquid outlet channel for a single server, and the cooling module 1503 is a cooling module for a single server. The liquid inlet channel 1501, the liquid outlet channel 1502 and the cooling module 1503 of different cabinet servers 1000 are independently arranged. The liquid inlet channel 1501 connects the liquid inlet connector 1600 and the cooling module 1503, the liquid outlet channel 1502 connects the liquid outlet connector 1700 and the cooling module 1503, and the cooling module 1503 is used to store the cooling working fluid, pump the cooling working fluid to the liquid inlet channel 1501, recover the cooling working fluid through the liquid outlet channel 1502, and cool the cooling working fluid.

[0070] Therefore, the first flow passage members 1 of different cabinet servers 1000 can realize independent cooling, which facilitates the arrangement of the cabinet servers 1000.

[0071] In some other embodiments, a plurality of cabinet servers 1000 are placed in the machine room. The first cooling device 1500 includes a liquid inlet channel 1501, a liquid outlet channel 1502, and a cooling module 1503. The liquid inlet channel 1501 is a total liquid inlet channel for cooling the plurality of cabinet servers 1000 in the machine room. The liquid outlet channel 1502 is a total liquid outlet channel for cooling the plurality of cabinet servers 1000 in the machine room. The cooling module 1503 is a total cooling module for cooling the plurality of cabinet servers 1000 in the machine room. The liquid inlet channel 1501 connects the liquid inlet connector 1600 and the cooling module 1503. The liquid outlet channel 1502 connects the liquid outlet connector 1700 and the cooling module 1503. The cooling module 1503 is used to store the cooling working fluid, pump the cooling working fluid into the total liquid inlet channel, recover the cooling working fluid through the total liquid outlet channel, and cool the cooling working fluid.

[0072] In some other embodiments, multiple cabinet servers 1000 are placed in the computer room. The first cooling device 1500 includes a liquid inlet channel 1501, a liquid outlet channel 1502 and a cooling module 1503. Different cabinet servers 1000 each have an independent liquid inlet channel 1501 and a liquid outlet channel 1502. The liquid inlet channels 1501 and liquid outlet channels 1502 of multiple cabinet servers 1000 are arranged in series to form a series passage, that is, the liquid outlet channel 1502 of the first cabinet server 1000 is connected to the liquid inlet channel 1501 of the second cabinet server 1000, and the cooling module 1503 is connected to the liquid inlet channel 1501 of the first cabinet server 1000, and is connected to the liquid outlet channel 1502 of the last cabinet server 1000 on the series passage.

[0073] It is understandable that there may be multiple implementations of the connection between the liquid inlet channels 1501 and the liquid outlet channels 1502 of the multiple cabinet servers 1000, which are not limited here.

[0074] It can be understood that, for the cabinet server 1000, the mechanical structures of the positive current-passing member 1310 and the negative current-passing member 1320 are substantially the same, except that the positive current-passing member 1310 is connected between the positive electrode of the first power supply 1400 and the positive electrode of the mainboard in the server node 1200, while the negative current-passing member 1320 is connected between the negative electrode of the first power supply 1400 and the negative electrode of the mainboard in the server node 1200. Therefore, the mechanical structures of the positive current-passing member 1310 and the negative current-passing member 1320 are described below by taking the first current-passing member 1 as an example.

[0075] In some embodiments, the first flow member 1 includes a first cooling channel 10. In other embodiments, please refer to Figure 4 The first flow member 1 includes two or more first cooling channels 10, each of which is respectively connected to the first cooling device 1500. Specifically, the liquid inlet 1012 and the liquid outlet 1022 of each first cooling channel 10 are respectively connected to the first cooling device 1500 through the liquid inlet joint 1600 and the liquid outlet joint 1700.

[0076] Please refer to Figure 3 , Figure 3 This is a schematic structural diagram of the first flow member 1 provided in the first embodiment of the present application.

[0077] In the first embodiment, the first flow member 1 is integrally formed, and the integral forming process includes but is not limited to casting, etc. The first cooling channel 10 is formed in the first flow member 1, and the first cooling channel 10 can be straight, U-shaped, S-shaped, M-shaped or spiral-shaped, etc.

[0078] In some other embodiments, the first flow member 1 may include at least two structural members. The at least two structural members are welded or crimped, and the first cooling channel 10 is formed between the at least two structural members.

[0079] In some embodiments, at least two structural members may be arranged and connected in one of the X-axis direction, the Y-axis direction, and the Z-axis direction. In other embodiments, at least two structural members may be arranged and connected in at least two of the X-axis direction, the Y-axis direction, and the Z-axis direction. Thus, a first cooling channel 10 with a more complex structure may be formed.

[0080] In some embodiments, the at least two structural members include only two structural members, and the first cooling channel 10 is formed between the two structural members. In some other embodiments, the at least two structural members may include three or more structural members, and the first cooling channel 10 is formed between three or more structural members, which is not limited here.

[0081] Therefore, in the embodiment of the present application, the first flow member 1 can be divided into at least two structural members, and each structural member can be processed to correspond to each part of the first cooling channel 10, and then at least two structural members can be connected together by welding or crimping to facilitate the mechanical processing of the first cooling channel 10.

[0082] In some embodiments, at least one of the at least two structural members is formed with a channel and / or a groove after removing part of the material, and the channel and / or the groove are used to form the first cooling channel 10 together. It can be understood that there are many ways for the channels and / or grooves on the at least two structural members to be interconnected to form the first cooling channel 10. For example, some of the at least two structural members are provided with channels, and other structural members are provided with grooves, and the channels and the grooves are connected to form the first cooling channel 10; for another example, some of the at least two structural members are provided with channels, and other structural members are also provided with channels, and the channels are connected to form the first cooling channel 10; for another example, some of the at least two structural members are provided with grooves, and other structural members are provided with grooves, and the grooves are connected to form the first cooling channel 10; for another example, some of the at least two structural members are provided with grooves, and other structural members are provided with grooves, and the grooves are connected to form the first cooling channel 10; for another example, some of the at least two structural members are provided with grooves, and other structural members are provided with neither channels nor grooves, and the grooves and other structural members that are neither provided with channels nor grooves form the first cooling channel 10 together.

[0083] Therefore, at least one of the at least two structural members has a portion of material removed to form a channel and / or a groove, thereby reducing the material usage cost and the weight of the first flow member 1 .

[0084] A number of specific embodiments are listed below to illustrate possible implementation forms of forming the first cooling channel 10 between at least two structural members. It should be noted that the possible implementation forms of forming the first cooling channel 10 between at least two structural members are not exhaustive, and in practical applications, there may be other implementation forms, which are not limited here.

[0085] Please refer to Figure 5 , Figure 5 This is a schematic structural diagram of the first flow member 1 provided in the second embodiment of the present application.

[0086] For the convenience of description, we define Figure 5The width direction of the first flow member 1 is the X-axis direction, the thickness direction is the Y-axis direction, and the height direction is the Z-axis direction.

Figure 5 The description of the orientation shown, with the positive direction of the Z axis as the "top", the negative direction of the Z axis as the "bottom", the negative direction of the X axis as the "left", the positive direction of the X axis as the "right", the positive direction of the Y axis as the "front", and the negative direction of the Y axis as the "back", does not constitute a limitation on the first flow member 1 in the actual application scenario.

[0087] Please refer to Figure 5 and Figure 6 , Figure 6 for Figure 5 In the second embodiment, at least two structural members include a first structural member 111 and a second structural member 112, the first structural member 111 is provided with a channel 1010, the second structural member 112 is provided with a groove 103, and when the first structural member 111 and the second structural member 112 are connected, the channel 1010 and the groove 103 together form a first cooling channel 10.

[0088] In the first embodiment, the first cooling channel 10 is in a U shape. The first structural member 111 and the second structural member 112 are arranged in the Z-axis direction of the first flow member 1, the second structural member 112 is located above the first structural member 111, the second structural member 112 is a relatively low cuboid, and the first structural member 111 is a relatively high cuboid. The channel 1010 opened on the first structural member 111 includes a first passage 101 and a second passage 102, and the first passage 101 and the second passage 102 are arranged side by side along the X-axis direction of the first flow member 1, and the first passage 101 and the second passage 102 respectively penetrate the first structural member 111 along the Z-axis direction of the first flow member 1; the groove 103 opened on the second structural member 112 is a groove close to one side of the first structural member 111; when the first structural member 111 and the second structural member 112 are arranged and spliced ​​in the Z-axis direction of the first flow member 1, the first end 1011 of the first passage 101 and the second end 1021 of the second passage 102 are respectively connected to the opposite ends of the groove 103 to form a U-shaped first cooling channel 10.

[0089] Thus, the first cooling channel 10 is formed by connecting the respective channels 1010 and the grooves 103 on the first structural member 111 and the second structural member 112 arranged along the Z-axis direction of the first flow member 1 .

[0090] In some embodiments, the first structural member 111 and the second structural member 112 may be connected by, but not limited to, welding, crimping, etc. In other embodiments, the first structural member 111 and the second structural member 112 may be connected by other means, such as bonding, etc.

[0091] In some embodiments, the first passage 101 and the second passage 102 can be formed on the first structural member 111 by drilling, and the groove 103 can be formed on the second structural member 112 by slotting. It is understood that in other embodiments, the first passage 101, the second passage 102 and the groove 103 can be formed by other processing methods, including but not limited to cutting, milling, drilling, etc.

[0092] In some embodiments, the first passage 101 and the second passage 102 are formed by drilling holes in the first structural member 111, and the groove 103 is formed by drilling grooves in the second structural member 112. In other embodiments, the first passage 101 and the second passage 102 are formed by drilling grooves in the first structural member 111 and passing pipes therethrough, and the groove 103 is formed by drilling grooves in the second structural member 112 and laying pipes therethrough.

[0093] Thus, the first passage 101 and the second passage 102 are formed by drilling holes on the first structural member 111, and the groove 103 is formed by drilling grooves on the second structural member 112. Therefore, the first passage 101 and the second passage 102 are formed by removing part of the material on the first structural member 111, and the groove 103 is formed by removing part of the material on the second structural member 112, which can reduce the mass of the first structural member 111 and the second structural member 112, save materials, and reduce costs.

[0094] It is understandable that in other implementations, the first cooling channel 10 is not limited to a U-shape, but may also be a straight shape, an S shape, an M shape, etc., which is not limited here.

[0095] It is understandable that in other embodiments, the first flow member 1 is not limited to being divided into two sections in the Z-axis direction, that is, the first flow member 1 includes a first structural member 111 and a second structural member 112 arranged along the Z-axis direction. Since the first cooling channel 10 can be in any shape, in order to facilitate the processing of the structure of each part of the first cooling channel 10, the first flow member 1 can also be divided into three-section structural members or more than three-section structural members in the Z-axis direction, which is not limited here.

[0096] Please refer to Figure 7 and Figure 8 , Figure 7 This is a schematic structural diagram of a first flow member 1 provided in the third embodiment of the present application. Figure 8 for Figure 7In the third embodiment, at least two structural members include a third structural member 113 and a fourth structural member 114, the third structural member 113 is provided with a first channel groove 1131, the fourth structural member 114 is provided with a second channel groove 1141, and when the third structural member 113 and the fourth structural member 114 are connected, the first channel groove 1131 and the second channel groove 1141 jointly form a first cooling channel 10.

[0097] Specifically, the first cooling channel 10 is in a U shape. The third structural member 113 and the fourth structural member 114 are arranged along the Y-axis direction of the first flow member 1. The first channel groove 1131 is provided in the third structural member 113, and the second channel groove 1141 is provided in the fourth structural member 114. The projections of the first channel groove 1131 and the second channel groove 1141 on the XZ plane are both in a U shape. Fig. 9 , Fig. 9 for Figure 7 Schematic diagram of the cross section at VIII-VIII. Fig. 9 It can be seen that the cross sections of the first channel groove 1131 and the second channel groove 1141 in the XY plane constitute the cross section of the first cooling channel 10 in the XY plane.

[0098] Thus, by splicing the first structural member 111 and the second structural member 112 arranged along the Y-axis direction of the first flow member 1 , the first channel groove 1131 on the first structural member 111 and the second channel groove 1141 on the second structural member 112 jointly form the first cooling channel 10 .

[0099] It is understandable that in other embodiments, the first cooling channel 10 may also be in a straight line shape, an S shape, an M shape, etc., which is not limited here. Therefore, in order to facilitate the processing of the structure of each part in the first cooling channel 10, the first flow member 1 may also be a three-stage structure or a structure of more than three stages in the Y-axis direction, which is not limited here.

[0100] Please refer to Fig.10 and Fig.11 , Fig.10 This is a schematic structural diagram of a first flow member 1 provided in a fourth embodiment of the present application. Fig.11 for Fig.10 In the fourth embodiment, the at least two structural members include a fifth structural member 115 and a sixth structural member 116, the fifth structural member 115 is provided with a first channel 1151, the sixth structural member 116 is provided with a second channel 1161, and when the fifth structural member 115 and the sixth structural member 116 are connected, the first channel 1151 and the second channel 1161 together form a first cooling channel 10.

[0101] Specifically, in the fourth embodiment, since the first cooling channel 10 is U-shaped, the fifth structural member 115 and the sixth structural member 116 are arranged along the X-axis direction of the first flow member 1. Therefore, the first channel 1151 is roughly L-shaped, and the second channel 1161 is roughly L-shaped. When the fifth structural member 115 and the sixth structural member 116 are connected, the first channel 1151 and the second channel 1161 are connected to form the first cooling channel 10.

[0102] Thus, the first cooling channel 10 can also be formed by connecting the first channel 1151 and the second channel 1161 of the fifth structure member 115 and the sixth structure member 116 arranged along the X-axis direction of the first flow member 1 .

[0103] In some embodiments, the first channel 1151 and the second channel 1161 may be symmetrically arranged with respect to the central axis of the first flow member 1 in the axial direction, or may be asymmetrically arranged, which is not limited here.

[0104] It is understandable that in other embodiments, the first cooling channel 10 may also be in an S shape or an M shape, etc. Therefore, in order to facilitate the processing of the structures of various parts in the first cooling channel 10, the first flow member 1 may also be a three-stage structure or a structure of more than three stages in the X-axis direction, which is not limited here.

[0105] Please refer to Fig.12 and Fig.13 , Fig.12 This is a schematic structural diagram of the first flow member 1 provided in the fifth embodiment of the present application. Fig.13 for Fig.12 In the fifth embodiment, the first flow member 1 includes a seventh structural member 117 and an eighth structural member 118. The eighth structural member 118 is a blocking member, and a third passage 1171 is formed on the seventh structural member 117. The eighth structural member 118 is plugged into the seventh structural member 117 and blocks part of the third passage 1171 to form the first cooling channel 10.

[0106] Therefore, in the embodiment of the present application, the third passage 1171 is formed by drilling a hole in the seventh structural member 117 , and then the first cooling channel 10 is formed through a portion of the third passage 1171 of the eighth structural member 118 .

[0107] In the fifth embodiment, the first cooling channel 10 is U-shaped. Therefore, the eighth structural member 118 blocks part of the third channel 1171 in the X-axis direction. It is understandable that in other embodiments, the first cooling channel 10 may be S-shaped, M-shaped, etc. Therefore, in order to process the shapes of various parts of the first cooling channel 10, the eighth structural member 118 may also block the third channel 1171 in the Y-axis direction and / or the Z-axis direction. Moreover, the eighth structural member 118 is not limited to one, but may be multiple, depending on the number of channels to be blocked, which is not limited here.

[0108] Please refer to Fig.14 and Fig.15 , Fig.14 This is a schematic structural diagram of a first flow member provided in the sixth embodiment of the present application, Fig.15 for Fig.14 Schematic diagram of decomposition. In the sixth embodiment, the first cooling channel 10 is S-shaped. The liquid inlet 1012 and the liquid outlet 1022 of the first cooling channel 10 are located at opposite ends of the first flow member 1. The first flow member 1 includes a ninth structural member 119 and a tenth structural member 1120. A third channel groove 1191 is provided on the ninth structural member 119, and a fourth channel groove 11201 is provided on the tenth structural member 1120. When the ninth structural member 119 and the tenth structural member 1120 are connected, the third channel groove 1191 and the fourth channel groove 11201 jointly form the first cooling channel 10.

[0109] Specifically, the ninth structural member 119 and the tenth structural member 1120 are arranged along the Y-axis direction of the first flow member 1. The third channel groove 1191 is opened in the ninth structural member 119, and the fourth channel groove 11201 is opened in the tenth structural member 1120. The projections of the third channel groove 1191 and the fourth channel groove 11201 on the XZ plane are both S-shaped. The cross-sections of the third channel groove 1191 and the fourth channel groove 11201 on the XY plane constitute the cross-section of the first cooling channel 10 on the XY plane.

[0110] Thus, by splicing the first structural member 111 and the second structural member 112 arranged along the Y-axis direction of the first flow member 1, the third channel groove 1191 on the ninth structural member 119 and the fourth channel groove 11201 of the tenth structural member 1120 jointly form the first cooling channel 10.

[0111] It is understandable that the S-shaped structural design of the first cooling channel 10 has a variety of different implementations, and the shapes and quantities of the structural members included in the first flow member 1 are different in different implementations, and the multiple structural members constituting the first flow member 1 are connected to each other. The principle followed when dividing the first flow member 1 into multiple structural members is to facilitate the processing of the grooves or holes in each structural member for forming the first cooling channel 10, specifically including but not limited to division along the X-axis direction, division along the Y-axis direction and / or division along the Z-axis direction, which is not limited here.

[0112] In some embodiments, the first flow-through component 1 is not only applied to the interior of the cabinet server 1000, but also can be applied to the outside of the cabinet server 1000. For example, the first flow-through component 1 can be a flow-through component connected to the path between the rectifier or uninterruptible power supply (UPS) and the cabinet server 1000, thereby improving the power flow capacity of the rectifier or uninterruptible power supply to the cabinet server 1000.

[0113] Please refer to Fig.16 , Fig.16 Schematic diagram of the structure of the rack server in the seventh embodiment of the present application. The rack server 2000 includes a chassis 2100, a mainboard 2200, a connector 2202, a second power supply 1400a and a second flow member 1a. The mainboard 2200 is installed in the chassis 2100. The connector 2202 includes a positive pin 2203 and a negative pin 2204, and the positive pin 2203 is used to connect the positive pole of the second power supply 1400a and the power layer of the mainboard 2200. The negative pin 2204 is used to connect the negative pole of the second power supply 1400a and the ground layer of the mainboard 2200. The second flow member 1a includes a pin 15, and the pin 15 specifically includes a first pin 11a and a second pin 12a. The first pin 11a of the second flow member 1a is connected to the first position of the power layer of the mainboard 2200, and the second pin 12a of the second flow member 1a is connected to the second position of the power layer of the mainboard 2200. The first position is adjacent to the connector 2202, and the second position is adjacent to the load 2300 of the mainboard 2200. The load 2300 can be, but is not limited to, a memory, various chip cards, a fan, etc. In some embodiments, the second position can be adjacent to the mainboard 2200 and is far from the second power supply 1400a. The second flow member 1a is used to deliver power to the rack server 200. Please refer to Fig.17The second flow member 1a has a second cooling channel 10a, and the second cooling channel 10a is used to communicate with the second cooling device 1500a to dissipate heat from the second flow member 1a. It is understandable that the rack server 2000 can be externally connected to the second cooling device 1500a, or the rack server 2000 can include the second cooling device 1500a, which is not limited here.

[0114] Thus, the second power supply 1400a can directly transmit power to the vicinity of the load 2300 relatively far from the second power supply 1400a through the second flow member 1a across a partial area of ​​the mainboard 2200, thereby reducing the resistance in the power transmission process and reducing the heat generation. A second cooling channel 10a is formed inside the second flow member 1a. The circulation of the cooling fluid in the second cooling channel 10a can timely dissipate heat for the second flow member 1a. The liquid cooling has high heat dissipation efficiency, can quickly cool the second flow member 1a, reduce temperature rise, and improve the flow capacity of the second flow member 1a, solving the problem of insufficient flow capacity of the second flow member 1a when high-power power is supplied, and meeting the high-power flow requirements. Moreover, since the first cooling channel 10 is formed inside the second flow member 1a, the amount of material used can be reduced, and the production cost and operation and maintenance cost can be reduced.

[0115] In some embodiments, the second flow member 1a is a flow bar applied to a 12V power supply network. In other embodiments, the second flow member 1a can be applied to power supply networks of other voltages, which is not limited here.

[0116] In the seventh embodiment, the second flow member 1a is integrally formed, wherein the integral forming process includes but is not limited to casting, etc. The second cooling channel 10a is formed in the second flow member 1a, and the second cooling channel 10a can be in a straight line shape, a U shape, an S shape, an M shape or a spiral shape, etc.

[0117] In some other embodiments, the second flow member 1a may include at least two structural members. The at least two structural members are welded or crimped, and the second cooling channel 10a is formed between the at least two structural members.

[0118] In some embodiments, at least two structural members may be arranged and connected in at least two directions of the X-axis direction, the Y-axis direction, and the Z-axis direction, thereby forming a second cooling channel 10a with a more complex structure.

[0119] In some embodiments, the at least two structural members include only two structural members, and the second cooling channel 10a is formed between the two structural members. In some other embodiments, the at least two structural members may include three or more structural members, and the second cooling channel 10a is formed between three or more structural members, which is not limited here.

[0120] Therefore, in the embodiment of the present application, the second flow member 1a can be divided into at least two structural members, and each structural member can be processed to correspond to the second cooling channel 10a, and then at least two structural members can be connected together by welding or crimping to facilitate the mechanical processing of the second cooling channel 10a.

[0121] In some embodiments, at least one of the at least two structural members is formed with a channel and / or a groove after removing part of the material, and the channel and / or the groove are used to form the second cooling channel 10a together. It can be understood that there are many ways for the channels and / or grooves on at least two structural members to be interconnected to form the second cooling channel 10a. For example, some of the at least two structural members are provided with channels, and other structural members are provided with grooves, and the channels and the grooves are connected to form the second cooling channel 10a; for another example, some of the at least two structural members are provided with channels, and other structural members are also provided with channels, and the channels are connected to form the second cooling channel 10a; for another example, some of the at least two structural members are provided with grooves, and other structural members are provided with grooves, and the grooves are connected to form the second cooling channel 10a; for another example, some of the at least two structural members are provided with grooves, and other structural members are provided with grooves, and the grooves are connected to form the second cooling channel 10a; for another example, some of the at least two structural members are provided with grooves, and other structural members are provided with neither channels nor grooves, and the grooves and other structural members that are neither provided with channels nor grooves form the second cooling channel 10a together.

[0122] Thus, at least one of the at least two structural members has a portion of material removed to form a channel and / or a groove, thereby reducing the material usage cost and the weight of the second flow member 1 a.

[0123] The following lists a number of specific embodiments to illustrate possible implementations of forming the second cooling channel 10a between at least two structural members. It should be noted that the possible implementations of forming the second cooling channel 10a between at least two structural members are not exhaustive, and in practical applications, there may be other implementations, which are not limited here.

[0124] Please refer to Fig.17 and Fig.18 , Fig.17 This is a schematic structural diagram of the second flow member in the seventh embodiment of the present application. Fig.18 for Fig.17 The second flow member 1a in the seventh embodiment is in the shape of a horizontal rectangular parallelepiped as a whole, and two pins 15 below the second flow member 1a are arranged on the mainboard 2200 of the rack server 2000 by welding or screw fixing.

[0125] In the seventh embodiment, the second cooling channel 10a is U-shaped. The second flow member 1a includes an eleventh structural member 121 and a twelfth structural member 122. The eleventh structural member 121 and the twelfth structural member 122 are arranged along the Y-axis direction of the second flow member 1a. A fifth channel groove 1211 is provided on the eleventh structural member 121. A sixth channel groove 1221 is provided on the twelfth structural member 122. Specifically, the projections of the fifth channel groove 1211 and the sixth channel groove 1221 on the XZ plane are both U-shaped. Please refer to Fig.19 , Fig.19 for Fig.17 Schematic cross-sectional view at XVII-XVII. The cross-sections of the fifth channel groove 1211 and the sixth channel groove 1221 in the YZ plane constitute the cross-section of the second cooling channel 10a in the YZ plane. When the eleventh structural member 121 and the twelfth structural member 122 are connected, the fifth channel groove 1211 and the sixth channel groove 1221 together form a U-shaped second cooling channel 10a.

[0126] Therefore, for the second flow member 1a suitable for the rack-mounted server 2000, the eleventh structural member 121 and the twelfth structural member 122 can be arranged along the Y-axis direction, the eleventh structural member 121 is provided with a fifth channel groove 1211, and the twelfth structural member 122 is provided with a sixth channel groove 1221, so that the second cooling channel 10a can be processed in the second flow member 1a.

[0127] It is understandable that in other embodiments, the second cooling channel 10a may also be in a straight line shape, an S shape, an M shape, a spiral shape, etc., which is not limited here.

[0128] It is understandable that, in other embodiments, the second flow member 1a is not limited to being divided into two sections in the Y-axis direction, that is, the second flow member 1a includes the eleventh structural member 121 and the twelfth structural member 122. Since the second cooling channel 10a can be in any shape, in order to facilitate the processing of the structure of each part of the second cooling channel 10a, the second flow member 1a can also be divided into three-section structural members or more than three-section structural members in the Y-axis direction, which is not limited here.

[0129] Please refer to Fig. 20 and Fig.21 , Fig. 20 This is a schematic structural diagram of the second flow member 1a in the eighth embodiment of the present application. Fig.21 for Fig. 20 The second flow member 1a in the eighth embodiment is in the shape of a horizontal rectangular parallelepiped as a whole, and two pins 15 below the second flow member 1a are arranged on the mainboard 2200 of the rack server 2000 by welding or screw fixing.

[0130] In the eighth embodiment, the second cooling channel 10a is U-shaped. The second flow member 1a includes a thirteenth structural member 123 and a fourteenth structural member 124. The thirteenth structural member 123 and the fourteenth structural member 124 are arranged along the Z-axis direction of the second flow member 1a. A fourth passage 1231 is provided on the thirteenth structural member 123. A fifth passage 1241 is provided on the fourteenth structural member 124. The fourth passage 1231 and the fifth passage 1241 are L-shaped respectively. When the thirteenth structural member 123 and the fourteenth structural member 124 are connected, the fourth passage 1231 and the fifth passage 12411 jointly form a U-shaped second cooling channel 10a.

[0131] Therefore, for the second flow member 1a suitable for the rack-mounted server 2000, the thirteenth structural member 123 and the fourteenth structural member 124 can be arranged along the Z-axis direction, and the fourth passage 1231 is opened on the thirteenth structural member 123. The fifth passage 1241 is opened on the fourteenth structural member 124, so that the second cooling channel 10a can be processed in the second flow member 1a.

[0132] It is understandable that in other embodiments, the second cooling channel 10a may also be in a straight line shape, an S shape, an M shape, a spiral shape, etc., which is not limited here.

[0133] It is understandable that, in other embodiments, the second flow member 1a is not limited to being divided into two sections in the Z-axis direction, that is, the second flow member 1a includes the thirteenth structural member 123 and the fourteenth structural member 124. Since the second cooling channel 10a can be in any shape, in order to facilitate the processing of the structure of each part of the second cooling channel 10a, the second flow member 1a can also be divided into three-section structural members or more than three-section structural members in the Z-axis direction, which is not limited here.

[0134] It is understandable that in other embodiments, the second flow member 1a may be divided into two sections in the X-axis direction. Since the second cooling channel 10a may be in any shape, in order to facilitate the processing of the structure of each part of the second cooling channel 10a, the second flow member 1a may be divided into three sections or more in the X-axis direction, which is not limited here.

[0135] In some embodiments, the second flow-through piece 1a is not only applied to the inside of the rack server 2000, but also can be applied to the outside of the rack server 2000. For example, the second flow-through piece 1a can be a flow-through piece connected to the passage between the rectifier or uninterruptible power supply and the rack server 2000, thereby improving the power flow capacity of the rectifier or uninterruptible power supply to the rack server 2000.

[0136] In some embodiments, for a rack server 2000 with a power of 30,000-50,000 watts, the inner diameter of the second cooling channel 10a of the second flow member 1a is 2-5 mm, the outer diameter width (dimension in the X-axis direction) of the second flow member 1a is 5-8 mm, and the outer diameter depth (dimension in the Y-axis direction) is 10-15 mm. It can be understood that the above dimensions of the inner diameter and outer diameter of the second flow member 1a are only examples. In actual applications, the dimensions of the inner diameter and outer diameter of the second flow member 1a can also be adaptively adjusted according to the needs of the flow capacity, and are not limited here.

[0137] The server or server node in the embodiment of the present application can be a general server, a GPU server, a DPU server or an AI server, etc., and is not limited here.

[0138] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
