[0032] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] An embodiment of the first aspect of the present application provides a power supply system 100.

[0034] As Figure 1 and Figure 2As shown in the figure, the power supply system 100 according to the embodiment of the first aspect of the present application includes: a power supply node 1 and a load node 2. There are multiple power supply nodes 1, and each power supply node 1 corresponds to at least one load node 2. A power supply copper bar 11 is provided on the outer surface of the power supply node 1 facing the load node 2, and a power-taking copper bar 21 is provided on the outer surface of the load node 2 facing the power supply node 1. The power-taking copper bar 21 is electrically connected to the electrical load 23 of the load node 2, and the power supply copper bar 11 is in surface contact with the power-taking copper bar 21 for electrical connection.

[0035] That is to say, each load node 2 can form an electrical connection with the corresponding power supply node 1 through the electrical connection between the power-taking copper bar 21 and the power supply copper bar 11. That is, through the electrical connection between the power-taking copper bar 21 and the power supply copper bar 11, a power supply path can be formed between the power supply node 1 and the load node 2. It can be understood that the power supply node 1 has the power supply ability, so that the power supply node 1 can deliver current to the load node 2 to ensure the stable operation of the load node 2. Among them, the power-taking copper bar 21 and the power supply copper bar 11 are electrically connected through contact, which can better shorten the distance between the power supply node 1 and the load node 2, thereby shortening the power supply path between the power supply node 1 and the electrical load 23 of the load node 2 to reduce power loss.

[0036] In addition, the contact area between the power supply copper bar 11 and the power-taking copper bar 21 is inversely proportional to the contact resistance between the two. That is, the smaller the contact area between the power supply copper bar 11 and the power-taking copper bar 21, the smaller the contact resistance between the power supply copper bar 11 and the power-taking copper bar 21; conversely, the larger the contact area between the power supply copper bar 11 and the power-taking copper bar 21, the smaller the contact resistance between the power supply copper bar 11 and the power-taking copper bar 21.

[0037] Therefore, the electrical connection between the power supply copper bar 11 and the power-taking copper bar 21 through surface contact can better increase the contact area between the power supply copper bar 11 and the power-taking copper bar 21, effectively reduce the contact resistance between the power supply copper bar 11 and the power-taking copper bar 21, thereby reducing the energy loss in the power supply process and improving the transmission efficiency of the current between the power supply copper bar 11 and the power-taking copper bar 21. At the same time, the temperature rise at the contact position of the power supply copper bar 11 and the power-taking copper bar 21 can be controlled to avoid overheating damage.

[0038] It should be noted that in the description of the present application, only the power supply copper bar 11 and the power-taking copper bar 21 are taken as examples of the electrical connection structure between the power supply node 1 and the load node 2 for the convenience of understanding the electrical connection method between the power supply node 1 and the load node 2, rather than a limitation on the material of the electrical connection structure between the power supply node 1 and the load node 2. For example, other materials with excellent electrical conductivity can also be used to replace the power supply copper bar 11 and the power-taking copper bar 21, as long as a stable electrical connection relationship can be formed between the power supply node 1 and the load node 2. No specific limitation is made here.

[0039] For the power supply system 100 according to the embodiments of the first aspect of the present application, the power supply copper bar 11 and the power-taking copper bar 21 are electrically connected through surface contact, which can shorten the power supply path between the power supply node 1 and the electrical load 23 of the load node 2, and can increase the contact area between the power supply copper bar 11 and the power-taking copper bar 21, effectively reducing the contact resistance between the power supply copper bar 11 and the power-taking copper bar 21. Thereby, the energy loss during power supply can be reduced and the transmission efficiency of the current between the power supply copper bar 11 and the power-taking copper bar 21 can be improved. At the same time, the temperature rise at the contact position of the power supply copper bar 11 and the power-taking copper bar 21 can be controlled to avoid overheating damage.

[0040] According to some embodiments of the present application, the number of load nodes 2 corresponding to each power supply node 1 does not exceed two. That is to say, the power supply node 1 can be electrically connected to the load node 2 in a one-to-one correspondence. For example, when the power requirement of a single load node 2 is high and a single power supply node 1 can only meet the power requirement of one load node 2, one power supply node 1 is only used to supply power to one load node 2; the power supply node 1 can also be electrically connected to two load nodes 2 at the same time. For example, when the power requirement of a single load node 2 is relatively low and the power requirements of two load nodes 2 are still within the power range that the power supply node 1 can provide, one power supply node 1 can supply power to two load nodes 2 at the same time. That is, the number of load nodes 2 electrically connected to the same power supply node 1 can be set according to the power requirement of the load node 2.

[0041] In other words, each power supply node 1 is electrically connected to at most two load nodes 2 at the same time, which can avoid an excessive number of load nodes 2 electrically connected to the same power supply node 1. It can be understood that the more load nodes 2 are connected to the same power supply node 1, the lower the power that each load node 2 can be allocated, or it will cause the power supply node 1 to be unable to meet the power requirements of multiple load nodes 2 at the same time. Therefore, by controlling the number of load nodes 2 electrically connected to the same power supply node 1, it is ensured that the power supply node 1 can meet the power requirements of the load node 2 to ensure the operating performance of the load node 2.

[0042] In some embodiments, the number of power supply copper bars 11 on each power supply node 1 is the same as and in one-to-one correspondence with the number of load nodes 2 corresponding to the power supply node 1. For example, when the power supply node 1 and the load node 2 are in one-to-one correspondence, only one power supply copper bar 11 can be provided on the power supply copper bar 11; when a power supply node 1 is electrically connected to the load node 2 at the same time, two power supply copper bars 11 can be provided on the power supply node 1, so that the power supply node 1 can be electrically connected to two load nodes 2 through the two power supply copper bars 11 respectively, which can ensure the safety of the power supply node 1 being electrically connected to two load nodes 2 at the same time.

[0043] It should be noted that only some of the embodiments are illustrated herein to facilitate understanding of the one-to-one connection relationship between the power supply busbars 11 and the load nodes 2, and it is not a limitation on the number of the power supply busbars 11. For example, in some embodiments, two power supply busbars 11 may be provided on the power supply node 1. When the power supply node 1 can only meet the power requirements of one high-power load node 2, the power supply node 1 may be electrically connected to the load node 2 through one of the power supply busbars 11, and the other power supply busbar 11 may be in a vacant state; when the power supply node 1 can simultaneously meet the power requirements of two low-power load nodes 2, the power supply node 1 may be electrically connected to the two load nodes 2 through the two power supply busbars 11 respectively. In other words, two power supply busbars 11 are fixedly provided on the power supply node 1, which can cope with different power requirements of different load nodes 2, so as to better ensure the consistency of the power supply node 1.

[0044] According to some embodiments of the present application, as Figure 2 shown, the two load nodes 2 corresponding to the same power supply node 1 are located on opposite sides of the power supply node 1. That is to say, when one power supply node 1 is correspondingly connected to two load nodes 2, the power supply node 1 is located between the two corresponding load nodes 2. Thus, the two load nodes 2 can make full use of the space on opposite sides of the power supply node 1 to avoid interference between the two load nodes 2. Moreover, the connection positions of the power supply node 1 and the two load nodes 2 are also located on opposite sides of the power supply node 1, and the connection and layout spaces are both larger, which can reduce the connection difficulty between the power supply node 1 and the two load nodes 2. At the same time, a larger layout space can be provided for the power supply busbars 11 and the power-taking busbars 21. In other words, larger-sized power supply busbars 11 and power-taking busbars 21 can be provided. The larger-sized power supply busbars 11 and power-taking busbars 21 can further increase the contact area between the power supply busbars 11 and the power-taking busbars 21, thereby reducing the contact resistance between the power supply node 1 and the load node 2, and further reducing the loss during the power transmission process.

[0045] According to some embodiments of the present application, multiple power supply nodes 1 are arranged at intervals, and at least one load node 2 is provided between two adjacent power supply nodes 1. That is to say, by arranging two adjacent power supply nodes 1 at intervals, an installation space can be provided for the load node 2 between the two adjacent power supply nodes 1, so as to reduce the distance between the load node 2 and the power supply node 1 and reduce the power transmission loss.

[0046] Among them, the distance between two adjacent power supply nodes 1 can be separated by the distance of one load node 2, and the load node 2 located between the two power supply nodes 1 is electrically connected to one of the power supply nodes 1; it can also be the distance between two adjacent power supply nodes 1 separated by two load nodes 2, and the two load nodes 2 located between the two power supply nodes 1 are respectively electrically connected to the two power supply nodes 1, and so on. The distance between two adjacent power supply nodes 1 can be flexibly adjusted according to the quantity relationship between the power supply nodes 1 and the load nodes 2, and no specific limitation is made here.

[0047] In some other embodiments, no installation space may be reserved for the load node 2 between some adjacent two power supply nodes 1. For example, the two power supply nodes 1 are arranged in the up-down direction and the two power supply nodes 1 can be arranged closely adjacent to each other. The two power supply nodes 1 are respectively electrically connected to one load node 2. Therefore, the load node 2 corresponding to the upper power supply node 1 can be arranged above the upper power supply node 1, and the load node 2 corresponding to the lower power supply node 1 can be arranged below the lower power supply node 1.

[0048] According to some embodiments of the present application, multiple power supply nodes 1 are arranged in the up-down direction, and the load nodes 2 and the corresponding power supply nodes 1 are arranged in the up-down direction. It can be understood that multiple loads in the related art are usually arranged in the up-down direction. Thus, by arranging the power supply nodes 1 and the load nodes 2 in the up-down direction, the arrangement direction of the load nodes 2 and the power supply nodes 1 can better adapt to the layout mode of power supply and load in the cabinet in the prior art, thereby reducing the difficulty of applying the power supply system 100 to the cabinet of the server, and further reducing the difficulty of adapting the power supply system 100 to the cabinet of the existing server.

[0049] According to some embodiments of the present application, multiple power supply nodes 1 are arranged at intervals, at least one load node 2 is provided between two adjacent power supply nodes 1, multiple power supply nodes 1 are arranged in the up-down direction, and the load nodes 2 and the corresponding power supply nodes 1 are arranged in the up-down direction. Thus, the distance between the load nodes 2 and the power supply nodes 1 can be reduced to reduce the loss of power transmission, and the difficulty of applying the power supply system 100 to the cabinet of the server can be reduced, and further the difficulty of adapting the power supply system 100 to the cabinet of the existing server can be reduced.

[0050] It should be noted that, according to the power requirements of multiple load nodes 2, the layout of the power supply node 1 and the load node 2 in the power supply system 100 can be flexibly adjusted. For example, in a specific embodiment, some power supply nodes 1 can meet the power requirements of two load nodes 2 at the same time, then the two load nodes 2 can be respectively arranged on the upper and lower sides of the power supply node 1; some power supply nodes 1 can only meet the power requirements of one load node 2, then the load node 2 can be arranged on the upper side of the power supply node 1, or the load node 2 can be arranged on the lower side of the power supply node 1, etc. Examples are not given one by one here.

[0051] According to some embodiments of the present application, the side of the power supply copper bar 11 facing the power taking copper bar 21 is the power supply surface 111, and the side of the power taking copper bar 21 facing the power supply copper bar 11 is the power taking surface 211. A positioning protrusion 212 is formed on one of the power supply surface 111 and the power taking surface 211, and a positioning groove 112 is formed on the other of the power supply surface 111 and the power taking surface 211. The positioning protrusion 212 is in plug-in fit with the positioning groove 112. For example, the positioning protrusion 212 can be formed on the power supply surface 111, and the positioning groove 112 can be formed on the power taking surface 211; alternatively, the positioning protrusion 212 can be formed on the power taking surface 211, and the positioning groove 112 can be formed on the power supply surface 111. No specific limitation is made here.

[0052] Among them, through the plug-in fit of the positioning protrusion 212 and the positioning groove 112, on the one hand, mutual limitation between the power supply copper bar 11 and the power taking copper bar 21 can be formed. For example, when the positioning protrusion 212 and the positioning groove 112 are plugged in the up and down direction, the movement of the power supply copper bar 11 relative to the power taking copper bar 21 in the horizontal direction can be restricted to ensure the stability of the connection between the power supply copper bar 11 and the power taking copper bar 21. On the other hand, the areas of the power supply surface 111 and the power taking surface 211 can be increased. For example, when the positioning protrusion 212 is formed on the power taking surface 211 and the positioning groove 112 is formed on the power supply surface 111, the area of the power taking surface 211 can be increased through the positioning protrusion 212, and the area of the power supply surface 111 can be increased through the positioning groove 112. The outer surface of the positioning protrusion 212 contacts the inner wall surface of the positioning groove 112, which can increase the contact area between the power supply surface 111 and the power taking surface 211, that is, increase the contact area between the power supply copper bar 11 and the power taking copper bar 21. Thus, the contact area between the power supply copper bar 11 and the power taking copper bar 21 can be further reduced to reduce the contact resistance, thereby improving the efficiency of the power supply node 1 in delivering power to the load node 2.

[0053] In some embodiments, the positioning protrusion 212 is formed on the power-taking surface 211, and the positioning groove 112 is formed on the power-supplying surface 111. Thus, the fitting position of the positioning protrusion 212 and the positioning groove 112 occupies the space on the power supply node 1, which can avoid occupying the space on the load node 2, so that more layout space can be provided for the electrical load 23 of the load node 2 to improve the performance of the load node 2. Among them, the cross-section of the positioning protrusion 212 in the front-back direction is square, that is, the cross-section of the power-taking copper bar 21 in the front-back direction is generally in a "convex" shape, and the positioning groove 112 is also square. Through the cooperation of the square positioning protrusion 212 and the square positioning groove 112, the limiting effect between the power-taking copper bar 21 and the power-supplying copper bar 11 can be improved, and the structure is simple and the processing cost is low.

[0054] It should be noted that this is only an example of the shape of one of the positioning protrusion 212 and the positioning groove 112, and it is not a limitation on the shapes of the positioning protrusion 212 and the positioning groove 112. The shapes of the positioning protrusion 212 and the positioning groove 112 are kept consistent, and it is ensured that the positioning protrusion 212 can be smoothly inserted into or taken out of the positioning groove 112. In addition, the positioning protrusion 212 and the positioning groove 112 can be in the shape of a strip extending in one direction, such as the front-back direction. For example, both the positioning groove 112 and the positioning protrusion 212 can be in the shape of a strip extending in the front-back direction, and the front end of the positioning groove 112 penetrates through the front wall surface of the power supply node 1. Therefore, during the installation process of the power supply node 1 and the load node 2, such as after installing the power supply node 1 in the cabinet first, the positioning protrusion 212 can be aligned with the positioning groove 112, and then the load node 2 can be pushed from front to back to make the load node 2 enter the cabinet, so as to reduce the installation difficulty of the power supply node 1 and the load node 2. Of course, the extending direction and shape of the positioning protrusion 212 and the positioning groove 112 can be flexibly adjusted according to the installation method of the power supply node 1 and the load node 2, etc. For example, multiple positioning protrusions 212 can be provided, etc., and no further examples will be given here.

[0055] In some embodiments, the projections of the power-supplying surface 111 and the power-taking surface 211 on the reference plane coincide, and the reference plane is perpendicular to the arrangement direction of the power supply node 1 and the load node 2. For example, if the power supply node 1 and the load node 2 extend in the up-down direction, the reference plane can be a horizontal plane. Thus, it can be ensured that the areas of the power-supplying surface 111 and the power-taking surface 211 are the same, while ensuring the surface contact between the power-supplying surface 111 and the power-taking surface 211, avoiding unnecessary waste of the power-supplying copper bar 11 and the power-taking copper bar 21, so as to reduce the costs of the power-supplying copper bar 11 and the power-taking copper bar 21.

[0056] According to some embodiments of the present application, an insulating structure 12 is provided on at least one of the power supply node 1 and the load node 2 on the outer peripheral side of the power supply copper bar 11 and the power-taking copper bar 21. Among them, the insulating structure 12 can be provided on the side of the power supply node 1 facing the load node 2, and the insulating structure 12 abuts against the side of the load node 2 facing the power supply node 1; it can also be that the insulating structure 12 is provided on the side of the load node 2 facing the power supply node 1, and the insulating structure 12 abuts against the side of the power supply node 1 facing the load node 2; it can also be that the insulating structure 12 is provided on both the side of the power supply node 1 facing the load node 2 and the side of the load node 2 facing the power supply node 1, and no specific limitation is made here.

[0057] Thus, an effective insulation block can be formed through the insulating structure 12, so as to avoid insulation breakdown of the connection position between the power supply copper bar 11 and the power-taking copper bar 21 to the outside such as the cabinet, thereby improving the safety of the power supply system 100. Among them, the size and position of the insulating structure 12 can be flexibly set according to requirements. For example, in some embodiments, the power supply node 1 and the load node 2 are arranged in the up-down direction, and the width dimension of the power supply copper bar 11 in the left-right direction is smaller than the width dimension of the power supply node 1 in the left-right direction. Thus, on the side of the power supply node 1 facing the load node 2, a layout space on the left and right sides of the power supply copper bar 11 can be reserved for the insulating structure 12. That is, the insulating structure 12 is provided on the side of the power supply node 1 facing the load node 2 and on the left and right sides of the power supply copper bar 11, which can avoid affecting the installation of the load node 2.

[0058] According to some embodiments of the present application, as Figure 3 and Figure 4 shown, the load node 2 further includes a main board 22, a plurality of electrical loads 23 and a plurality of connection copper bars 24. The electrical loads 23 are arranged on the main board 22, and a plurality of connection copper bars 24 are arranged between the main board 22 and the power-taking copper bar 21. At least part of the electrical loads 23 are electrically connected to the power-taking copper bar 21 through corresponding and independent connection copper bars 24. That is to say, at least part of the electrical loads 23 can directly take power from the power-taking copper bar 21 through the connection copper bars 24. Thus, through the plurality of connection copper bars 24, the difficulty of the plurality of electrical loads 23 taking power from the power-taking copper bar 21 can be better reduced, and the power transmission path between the electrical loads 23 and the power-taking copper bar 21 can be shortened. Thus, the power transmission path from the power supply node 1 to the electrical loads 23 can be shortened to reduce the transmission loss.

[0059] Among them, the position and shape of the connection copper bar 24 can be flexibly adjusted according to the position, shape and avoidance requirements of the electrical load 23. The connection copper bar 24 is arranged at the edge of the corresponding electrical load 23. The connection copper bar 24 can be strip-shaped or L-shaped. The width of the connection copper bar 24 can be set to the same value as the width of the corresponding electrical load 23 to reduce the occupied space, etc.

[0060] Specifically, taking the layout shown in Figure 4 as an example, the electrical load 23 includes a processor 23a, a radiator 23b, a memory 23c, a fan 23d, a hard disk 23e, etc. There are multiple fans 23d arranged in a direction. Therefore, the connection busbar 24 corresponding to the multiple fans 23d can be set as a long strip in the same direction as the arrangement direction of the multiple fans 23d, so that the connection busbar 24 can be electrically connected to the multiple fans 23d at the same time to supply power to the multiple fans 23d at the same time. The memory 23c is in the shape of a long strip and is located between the two processors 23a. The connection busbar 24 corresponding to the memory 23c is located on one side of the memory 23c along the length direction and has the same width as the memory 23c.

[0061] According to some embodiments of the present application, the projection of the power-taking busbar 21 on the reference plane is the first projection, and the projection of the connection busbar 24 on the reference plane is the second projection. The second projection is located within the first projection, and the reference plane is perpendicular to the arrangement direction of the power supply node 1 and the load node 2. That is to say, the power-taking busbar 21 can completely cover all the connection busbars 24, so that the connection busbar 24 can connect the power-taking busbar 21 and the corresponding electrical load 23 with a shorter path, that is, the connection busbar 24 can have a shorter length, thereby shortening the power transmission path between the electrical load 23 and the power-taking busbar 21 and reducing the transmission loss.

[0062] According to some embodiments of the present application, the power supply node 1 further includes: a busbar 13 and a plurality of power supply units 14. The plurality of power supply units 14 are connected in parallel to the busbar 13, and the busbar 13 is electrically connected to the power supply busbar 11. That is to say, in the power supply node 1, the plurality of power supply units 14 are connected in parallel and electrically connected to the power supply busbar 11 through the busbar 13. Among them, the higher power requirements of the load node 2 can be met through the plurality of power supply units 14 to ensure the performance of the load node 2. Specifically, a plurality of connectors 15 are arranged at intervals on the busbar 13. The number of the plurality of connectors 15 is the same as that of the plurality of power supply units 14 and corresponds one by one. The plurality of power supply units 14 are respectively electrically connected to the busbar 13 through the corresponding connectors 15. Specifically, the power supply unit 14 is connected to the power grid and can convert the alternating current of the power grid into direct current for the electrical load 23 to use.

[0063] Embodiments of the second aspect of the present application provide a server.

[0064] The server according to the embodiment of the second aspect of the present application includes: the power supply system 100 in any of the above embodiments.

[0065] According to the server of the second aspect embodiment of the present application, since it has the power supply system 100 in any of the above embodiments, the power supply copper bar 11 and the power taking copper bar 21 are electrically connected through surface contact, which can shorten the power supply path between the power supply node 1 and the power consumption load 23 of the load node 2, and can increase the contact area between the power supply copper bar 11 and the power taking copper bar 21, effectively reducing the contact resistance between the power supply copper bar 11 and the power taking copper bar 21. Thus, the energy loss during power supply can be reduced and the transmission efficiency of the current between the power supply copper bar 11 and the power taking copper bar 21 can be improved. At the same time, the temperature rise at the contact position of the power supply copper bar 11 and the power taking copper bar 21 can be controlled to avoid overheating damage.

[0066] Specifically, as Figure 7 shown, the design process of the power supply system 100 of the server is as follows: First, select the number of power supply nodes 1 and the number of power supply units 14 in the power supply node 1 according to the total power requirement to ensure that the power supply node 1 can meet the total power supply demand of the server; further, design the shape and structure of the power taking copper bar 21 of the load node 2 according to the power requirement and impedance of a single load node 2 to ensure that the power taking copper bar 21 can meet the power requirement of a single load node 2; further, after determining the structure of the power taking copper bar 21, determine the structure of the power supply copper bar 11 of the power supply node 1 according to the structure of the power taking copper bar 21 to ensure that the power taking copper bar 21 and the power supply copper bar 11 can fit together to achieve surface contact connection. At the same time, set the insulating structure 12 on the power supply node 1 according to the position of the power supply copper bar 11 to ensure the insulation performance at the connection position of the power supply copper bar 11 and the power taking copper bar 21; further, design the position of the connection copper bar 24 according to the positions of multiple power consumption loads 23 on the main board 22.
