A server power supply device and a server

[0001] Cross-reference to related applications

[0002] This disclosure claims the benefit and priority of Chinese Patent Application No. 202411206051.X, filed with the Chinese Patent Office on August 30, 2024, entitled “A Server Power Supply Device and Server”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of server power supply technology, and in particular to a server power supply device. Furthermore, this disclosure also provides a server including the aforementioned server power supply device. Background Technology

[0004] In recent years, with the rapid development of artificial intelligence technology, the demand for server computing power has been increasing, server performance has been improving rapidly, and the scale of data centers has also been increasing, which has led to the problem of increased server power consumption.

[0005] Currently, one traditional power supply method is CRPS (Common Redundancy Power Supply). CRPS provides redundant power, ensuring continuous operation of equipment even if one power source fails, another can continue to supply power. However, it has a limitation on maximum power output. The other method is centralized power supply, which provides power to multiple devices through specific equipment and systems. This method has shortcomings in conversion efficiency.

[0006] As server power consumption increases further, a greater number of power supply modules are needed to provide power to the server system. However, in the process of increasing the number of power supply modules, since the power supply modules are basically of a standard structure, they cannot be matched according to the server's power consumption. This can lead to a mismatch between the actual power supply capacity of all power supply modules and the server's power consumption, which can easily result in wasted energy or affect the normal operation of the server.

[0089] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this disclosure.

[0090] This disclosure provides a server power supply device, which allows for the selection of the number of DC power supply devices to be installed according to the actual needs of the server, thereby avoiding a mismatch between the actual power supply capacity of the power module and the power consumption of the server.

[0091] In addition, this disclosure also provides a server including the aforementioned server power supply equipment.

[0092] This specific embodiment discloses a server power supply device, including a device housing 1, a power supply board 2, and at least one DC power supply device 3. The power supply board 2 is installed inside the device housing 1 and is provided with an external power connector 2-4 for connecting to an external power source, a connection part 2-1 for electrically connecting to a server motherboard, and at least two DC power connectors. The DC power supply device 3 is provided with a plug-in part for plugging into the DC power connectors. The DC power module is used to convert the DC power connected to the external power connector 2-4 into DC power of another voltage. The DC power supply can be selectively plugged into the DC power connectors.

[0093] It should be noted that in this specific embodiment, the DC power supply device 3 can be selectively inserted into the DC power connector, which means that in actual use, the number of DC power supply devices 3 inserted into the DC power connector can be selected according to actual needs.

[0094] In actual use, the device casing 1 needs to be assembled first, and the power supply board 2 needs to be installed inside the device casing 1. Then, according to the actual power supply requirements of the server, the appropriate number of DC power supply devices 3 to be inserted is selected, and the plug-in part of the DC power supply device 3 is inserted into the DC power connector.

[0095] In this specific embodiment, the number of DC power supply devices 3 to be installed can be selected according to the actual power supply needs of the server during actual use. When the actual power consumption of the server increases, the number of DC power supply devices 3 can be appropriately increased to avoid affecting the normal use of the server due to insufficient power supply; when the actual power consumption of the server decreases, the number of DC power supply devices 3 can be appropriately reduced to avoid energy waste. Compared with the prior art of directly adding or removing power modules as a whole, in this disclosure, the number of DC power supply devices 3 installed in the same power supply equipment can be selected according to actual needs, which can effectively avoid energy waste while meeting the power consumption requirements of the server.

[0096] Based on the above embodiments, the DC power supply device 3 can include a PCB module 3-1 and a heat sink module 3-2. The PCB module 3-1 includes a gold finger board 3-1-1 and a power board 3-1-2 soldered to the gold finger board 3-1-1. The plug-in part is the gold finger provided on the gold finger board 3-1-1. The heat sink module 3-2 includes a first heat sink 3-2-1 located outside the power board 3-1-2, a second heat sink 3-2-3 located outside the gold finger board 3-1-1, and a third heat sink 3-2-2 disposed between the gold finger board 3-1-1 and the power board 3-1-2. The heat sink module 3-2 is connected to the PCB module 3-1.

[0097] The specific structure of the DC power supply device 3 is shown in Figure 10. The gold finger plate 3-1-1 and the power board 3-1-2 have the same length, but the width of the power board 3-1-2 is greater than the width of the gold finger plate 3-1-1. In actual installation, the top ends of the gold finger plate 3-1-1 and the power board 3-1-2 are aligned and connected as a whole by welding with copper busbars. As shown in Figures 11 and 12, the front end of the gold finger plate 3-1-1 corresponds to the gold finger of the primary high-voltage connector 2-5, and the rear end corresponds to the gold finger of the secondary low-voltage connector 2-6. The gold finger plate 3-1-1 has one screw hole at each end for fixing. Magnetic cores are provided on both sides of the power board 3-1-2 in the thickness direction. The gold finger plate 3-1-1 has a first clearance hole to avoid one of the magnetic cores, and the third heat sink 3-2-2 has a second clearance hole to avoid the other magnetic core. The power board 3-1-2 has two screw holes at each end for fixing.

[0098] As shown in Figure 13, the outer side of the first heat sink 3-2-1 is provided with a first horizontal heat dissipation tooth, and the two ends of the first heat sink 3-2-1 along its length are provided with a first heat dissipation vent. The inner side of the first heat sink 3-2-1 is provided with a stepped post, which is used to position the power board 3-1-2. The stepped post is provided with a screw through hole, and the screw passes through the screw through hole and connects to the screw hole of the power board 3-1-2. Specifically, for other devices installed on the power board 3-1-2, a clearance recess can be provided in the first heat sink 3-2-1.

[0099] The third heat sink 3-2-2 is installed between the power board 3-1-2 and the gold finger board 3-1-1. The third heat sink 3-2-2 is provided with positioning holes, which are used to engage with the claws on the first heat sink 3-2-1 for positioning. The third heat sink 3-2-2 is provided with studs, and the gold finger board 3-1-1 is fixedly connected to the third heat sink 3-2-2 by screws.

[0100] The outer side of the second radiator 3-2-3 is provided with a second horizontal heat dissipation tooth.

[0101] In this specific embodiment, by setting a first heat sink 3-2-1, a second heat sink 3-2-3, and a third heat sink 3-2-2, with the third heat sink 3-2-2 positioned between the power board 3-1-2 and the gold finger board 3-1-1, the second heat sink 3-2-3 positioned on the outside of the gold finger board 3-1-1, and the first heat sink 3-2-1 positioned on the outside of the power board 3-1-2, the heat dissipation efficiency of the power board 3-1-2 can be effectively improved, thus enhancing the heat dissipation effect.

[0102] Based on the above embodiments, the DC power supply device 3 may further include a guide module 3-3 and an operation module 3-4. The guide module 3-3 includes a first guide device 3-3-2 and a second guide device 3-3-1. The first guide device 3-3-2 is fixed to the operation module 3-4 and is slidably disposed relative to the device housing 1 along a first direction. The first direction is disposed along the extension direction of the DC power connector. The second guide device 3-3-1 includes an active guide and a first slide groove 3-3-1-3. One of the active guide and the first slide groove 3-3-1-3 is disposed on the heat sink module 3-2, and the other is disposed on the operation module 3-4. The length direction of the active guide has extensions in both the first direction and the second direction. The second direction is parallel to the insertion direction of the DC power connector. When the second guide device 3-3-1 moves along the first direction, the first guide device 3-3-2 slides along the first direction. The movement direction of the PCB module 3-1 has components along both the first and second directions.

[0103] Specifically, the first guide device 3-3-2 may include a crossbeam 3-3-2-1 and a longitudinal beam 3-3-2-2. The length of the crossbeam 3-3-2-1 extends along a first direction, and the length of the longitudinal beam 3-3-2-2 extends along a second direction. The equipment housing 1 is provided with a first slide rail for cooperating with the crossbeam 3-3-2-1 and a positioning stop provided at the end of the first slide rail. The crossbeam 3-3-2-1 is slidably disposed along the first slide rail. When the crossbeam 3-3-2-1 slides to contact the positioning stop, the plug-in part is plugged into and cooperates with the corresponding DC power connector. The second radiator 3-2-3 is provided with a second slide rail for cooperating with the longitudinal beam 3-3-2-2. The longitudinal beam 3-3-2-2 is slidable relative to the second slide rail.

[0104] As shown in Figure 18, the first guide device 3-3-2 includes a crossbeam 3-3-2-1 and two longitudinal beams 3-3-2-2 perpendicular to the crossbeam 3-3-2-1. The first slide is a C-shaped slide rail 1-2-2 set on the inner side wall of the top cover 1-2. The specific structure of the C-shaped slide rail 1-2-2 is shown in Figures 7 and 8. In actual use, the crossbeam 3-3-2-1 needs to be inserted into the C-shaped slide rail 1-2-2. By pushing the operation module 3-4, the crossbeam 3-3-2-1 slides along the C-shaped slide rail 1-2-2. The end of the C-shaped slide rail 1-2-2 is provided with a positioning stop. When the plug-in part is plugged into the corresponding DC power connector, the crossbeam 3-3-2-1 slides along the C-shaped slide rail 1-2-2 to the position of contact with the positioning stop.

[0105] As shown in Figure 8, the inner surface of the C-shaped slide rail 1-2-2 is provided with a raised structure. Correspondingly, the crossbeam 3-3-2-1 needs to be provided with a guide groove for cooperating with the raised structure. The setting of the raised structure and the guide groove can fix the relative position of the crossbeam 3-3-2-1 with respect to the C-shaped slide rail 1-2-2 in a plane perpendicular to the sliding direction.

[0106] Furthermore, the active guide can include a connecting guide rod 3-3-1-1 and an inclined guide rod 3-3-1-2. One end of the connecting guide rod 3-3-1-1 is connected to the operation module 3-4, and the other end of the connecting guide rod 3-3-1-1 is connected to the inclined guide rod 3-3-1-2. The inclined guide rod 3-3-1-2 has extensions along both a first direction and a second direction in its length direction. A first slide groove 3-3-1-3 is disposed on the second radiator 3-2-3 and is sleeved on the outer periphery of the inclined guide rod 3-3-1-2. The inclined guide rod 3-3-1-2 is slidably disposed relative to the first slide groove 3-3-1-3.

[0107] In practical use, when installing the DC power supply device 3, firstly, the crossbeam 3-3-2-1 of the DC power supply device 3 needs to be aligned with the first slide rail of the top cover 1-2. Then, the DC power supply device 3 is pushed towards the inside of the equipment housing 1, causing the crossbeam 3-3-2-1 to slide along the first slide rail. Simultaneously, the DC power supply device 3 moves towards the inside of the equipment housing 1. During this process, the inclined guide rod 3-3-1-2 slides relative to the first slide groove 3-3-1-3. Since the extension direction of the inclined guide rod 3-3-1-2 has components of both the first and second directions, during the sliding process of the inclined guide rod 3-3-1-2 relative to the first slide groove 3-3-1-3, the first slide groove 3-3-1-3 will be... -3-1-3 moves along the first direction and downwards along the second direction. Since the first slide groove 3-3-1-3 is set on the second heat sink 3-2-3, the second heat sink 3-2-3 moves along the first direction and downwards along the second direction towards the DC power connector. During the movement of the second heat sink 3-2-3 along the second direction, the second slide rail slides relative to the longitudinal beam 3-3-2-2 along the second direction. The cooperation between the second slide rail and the longitudinal beam 3-3-2-2 plays a guiding role. The second heat sink 3-2-3 drives the gold finger plate 3-1-1 to move along the first and second directions, thereby realizing the insertion and engagement of the gold finger and the DC power connector.

[0108] As shown in Figure 15, one end of the second radiator 3-2-3 is provided with a Z-shaped bending structure. The Z-shaped bending structure is provided with an inclined surface. The first slide groove 3-3-1-3 is an annular structure. The annular first slide groove 3-3-1-3 can be fitted onto the outer periphery of the inclined guide rod 3-3-1-2.

[0109] In this specific embodiment, the cooperation between the inclined guide rod 3-3-1-2 and the first sliding groove 3-3-1-3 drives the second heat sink 3-2-3 to move along the inclined direction of the inclined guide rod 3-3-1-2, thereby making the moving direction of the second heat sink 3-2-3 simultaneously have components of the first direction and the second direction; and because the second heat sink 3-2-3 is fixedly connected to the gold finger plate 3-1-1, the moving direction of the gold finger plate 3-1-1 simultaneously has components of the first direction and the second direction, realizing the movement along the first direction... When the operation module 3-4 is pushed inward, the gold finger plate 3-1-1 moves towards the inside of the device housing 1 in the first direction and towards the side closer to the DC power connector in the second direction, thereby realizing the insertion and engagement of the gold finger plate 3-1-1 and the DC power connector; when the operation module 3-4 is pulled outward in the first direction, the gold finger plate 3-1-1 moves towards the outside of the device housing 1 in the first direction and towards the side farther away from the DC power connector in the second direction, thereby realizing the disengagement of the gold finger plate 3-1-1 and the DC power connector.

[0110] In this specific embodiment, during the insertion and disengagement of the DC power supply device 3 and the DC power connector, it is not necessary to push the DC power supply device 3 inward or pull it outward in the first direction. It is not necessary to disassemble the device housing 1 before operation, making the installation and disassembly of the DC power supply device 3 more convenient and easier to operate.

[0111] Based on the above embodiments, the operation module 3-4 may include an operation housing 3-4-1 and a locking assembly; a crossbeam 3-3-2-1 is fixedly connected to the operation housing 3-4-1; an active guide is movably disposed in the operation housing 3-4-1 along a first direction between a first position and a second position; when the active guide moves to the first position, the plug-in part is disconnected from the DC power connector; when the active guide moves to the second position, the plug-in part is plugged into the DC power connector; the locking assembly is disposed in the operation housing 3-4-1, and when the active guide moves to the first position, the locking assembly is unlocked from the active guide; when the active guide moves to the second position, the locking assembly is locked and fixed to the active guide.

[0112] Specifically, the locking assembly may include a locking latch 3-4-3, a first elastic reset member 3-4-4, and an unlocking button 3-4-5; wherein, the locking latch 3-4-3 is rotatably mounted on the operating housing 3-4-1, one of the locking latch 3-4-3 and the active guide member is provided with a locking protrusion 3-4-3-1, and the other of the locking latch 3-4-3 and the active guide member is provided with a locking groove 3-3-1-4 for engaging with the locking protrusion 3-4-3-1 for locking; one end of the first elastic reset member 3-4-4 abuts against the operating housing 3-4-1, and the other end abuts against the locking latch 3-4-3; the unlocking button 3-4-5 follows the first elastic reset... The telescopic direction of component 3-4-4 is movably disposed on the operating housing 3-4-1 between the third and fourth positions, and the unlocking button 3-4-5 is connected to the locking buckle 3-4-3; the locking buckle 3-4-3 is rotatably disposed between the first angular position and the second angular position; when the locking buckle 3-4-3 is in the first angular position, the unlocking button 3-4-5 is in the third position, and the locking protrusion 3-4-3-1 and the locking groove 3-3-1-4 cooperate to lock; when the locking buckle 3-4-3 is in the second angular position, the unlocking button 3-4-5 is in the fourth position, and the locking protrusion 3-4-3-1 and the locking groove 3-3-1-4 are released from locking.

[0113] Based on the above embodiments, the operation module 3-4 may further include a guide assembly. The operation housing 3-4-1 includes a first housing and a second housing that are fastened together. The inner sides of both the first housing and the second housing are provided with a second slide groove 3-4-9 extending in a first direction. The guide assembly includes a roller 3-4-6, a guide post 3-4-7, and a second elastic reset member 3-4-2. The roller 3-4-6 is disposed at one end of the active guide member and is slidably disposed along the extension direction of the second slide groove 3-4-9. The length direction of the guide post 3-4-7 is disposed along the extension direction of the second slide groove 3-4-9. One end of the second elastic reset member 3-4-2 abuts against the inner wall of the second slide groove 3-4-9, and the other end abuts against the guide post 3-4-7.

[0114] As shown in Figures 16 and 17, the inclined guide rod 3-3-1-2, the connecting guide rod 3-3-1-1, and the rod-shaped part of the guide assembly are an integral structure. The rod-shaped part of the guide assembly is provided with a mounting block. Rollers 3-4-6 are provided on opposite sides of the mounting block. The axial direction of the rollers 3-4-6 is perpendicular to the first direction. The axial direction of the guide post 3-4-7 is provided along the first direction. The operating housing 3-4-1 is provided with an operating handle 3-4-8 connected to the active guide. The operating handle 3-4-8 has a C-shaped structure, and the inner side of the operating handle 3-4-8 is provided with a contoured recess for easy gripping.

[0115] As shown in Figure 19, the operating housing 3-4-1 is provided with a snap-fit ​​part for fixed connection with the crossbeam 3-3-2-1 of the first guide device 3-3-2, so that the first guide device 3-3-2 can move synchronously with the operating housing 3-4-1; the operating housing 3-4-1 is provided with a mounting position for installing the second guide device 3-3-1, so that the operating housing 3-4-1 includes a first housing and a second housing that are snapped together. In actual use, the second guide device 3-3-1 can be sandwiched between the first housing and the second housing.

[0116] As shown in Figures 22 and 25, the DC power supply device 3 is not plugged into the DC power connector at this time. In actual use, firstly, the crossbeam 3-3-2-1 needs to be aligned with the C-shaped slide rail 1-2-2 of the top cover 1-2. Then, hold the operating handle 3-4-8 and push the operating module 3-4 inward. The operating module 3-4 drives the second guide device 3-3-1 to move along the first direction. During the movement of the second guide device 3-3-1 along the first direction, due to the cooperation between the first slide groove 3-3-1-3 and the inclined guide rod 3-3-1-2 in the second guide device 3-3-1, the second guide device 3- During the movement of 3-1 along the first direction, the second heat sink 3-2-3, which is equipped with the first slide groove 3-3-1-3, will move along the first direction. At the same time, the second heat sink 3-2-3 moves downward along the second direction until the gold finger plate 3-1-1 is plugged into the DC power connector. At this time, as shown in Figures 23 and 24, the locking recess of the second guide device 3-3-1 and the locking protrusion 3-4-3-1 on the locking buckle 3-4-3 cooperate to lock. Under the elastic force of the first elastic reset member 3-4-4, the locking cooperation between the second guide device 3-3-1 and the locking buckle 3-4-3 is realized.

[0117] When it is necessary to release the locking engagement between the second guide device 3-3-1 and the locking latch 3-4-3, press the unlock button 3-4-5 in the first direction. The position where the unlock button 3-4-5 contacts the locking latch 3-4-3 is offset from the rotation axis of the locking latch 3-4-3. Therefore, during the process of pressing the unlock button 3-4-5, the locking latch 3-4-3 in Figure 23 overcomes the elastic force of the first elastic reset member 3-4-4 and rotates clockwise until the locking protrusion 3-4-3-1 of the locking latch 3-4-3 disengages from the locking groove 3-3-1-4 of the second guide device 3-3-1. At this time, the operating handle 3-4-8 can be pulled outward in the first direction. At the same time, under the action of the elastic force of the second elastic reset member 3-4-2, the second guide device 3-3-1 moves outward in the first direction. During the movement of the second guide device 3-3-1 outward in the first direction, the first slide groove 3-3-1-3 cooperates with the inclined guide rod 3-3-1-2 in the second guide device 3-3-1, which will drive the second heat sink 3-2-3, which is equipped with the first slide groove 3-3-1-3, to move outward in the first direction. At the same time, the second heat sink 3-2-3 moves upward in the second direction. Since the second heat sink 3-2-3 is fixedly connected to the gold finger plate 3-1-1, it will drive the gold finger plate 3-1-1 to move outward in the first direction. At the same time, the gold finger plate 3-1-1 moves upward in the second direction, so that the gold finger plate 3-1-1 is disconnected from the DC power connector. By continuing to pull the operating handle 3-4-8 outward, the DC power device 3 can be taken out from the equipment housing 1.

[0118] It should be noted that, as shown in Figures 22 and 23, in this specific embodiment, the rotation axis of the locking latch 3-4-3 is not collinear with the position of the locking latch 3-4-3 in contact with the unlocking button 3-4-5, and the rotation axis of the locking latch 3-4-3 is not collinear with the position of the first elastic reset member 3-4-4 in contact with the locking latch 3-4-3. Therefore, under the elastic force of the first elastic reset member 3-4-4, the locking latch 3-4-3 will generate a counterclockwise downward movement in the direction shown in Figures 22 and 23. The tendency of the needle to rotate causes the first elastic reset member 3-4-4 to provide locking force for the engagement of the locking protrusion 3-4-3-1 of the locking buckle 3-4-3 and the locking recess of the second guide device 3-3-1; during the pressing of the unlock button 3-4-5, the locking buckle 3-4-3 will rotate clockwise in the direction shown in Figures 22 and 23, thereby releasing the locking protrusion 3-4-3-1 of the locking buckle 3-4-3 from the locking recess of the second guide device 3-3-1.

[0119] In this specific embodiment, by setting the unlocking button 3-4-5, the locking buckle 3-4-3 and the second guide device 3-3-1 can be easily engaged, making operation convenient. Furthermore, the setting of the locking buckle 3-4-3 can limit the position of the gold finger plate 3-1-1 in the first direction, preventing the gold finger plate 3-1-1 from accidentally disengaging from the DC power connector.

[0120] In one specific embodiment, the power supply substrate 2 may include a substrate body, an external power connector 2-4, a capacitor 2-3, a relay 2-2, a connecting part 2-1, and a DC power connector; wherein, the external power connector 2-4 is mounted on the substrate body; the capacitor 2-3 is mounted on the substrate body for filtering and energy storage, and the capacitor 2-3 is electrically connected to the external power connector 2-4; the relay 2-2 is mounted on the substrate body for controlling the on / off state of the circuit; the connecting part 2-1 is a power gold finger disposed on the substrate body; the DC power connector is disposed on one side of the substrate body in the thickness direction, and the DC power connector includes a primary high-voltage connector 2-5 and a secondary low-voltage connector 2-6; the external power connector 2-4, the capacitor 2-3, and the relay 2-2 are arranged sequentially along the same straight line.

[0121] As shown in Figure 9, in this specific embodiment, the external power connector 2-4, capacitor 2-3, and relay 2-2 are arranged sequentially along the same straight line, making the structural layout of the power supply board 2 more reasonable.

[0122] On the one hand, along the thickness direction of the substrate body, the power gold finger is located on the side of the substrate body where the DC power connector is disposed; and the upper surface of the power gold finger is higher than the surface of the substrate body where the DC power connector is mounted, and the lower surface of the power gold finger is higher than the surface of the substrate body that is away from the DC power connector.

[0123] In this specific embodiment, the power supply gold fingers are higher than the substrate body and are connected to the substrate body via copper busbars. This ensures that the position of the gold fingers in the server power supply device is the same as that of the standard CRPS power module, allowing for direct replacement. This reduces the height of the substrate body within the server power supply device and increases the space above the substrate body. While ensuring the compatibility of the server power supply device, this improves the utilization rate of the internal space of the device casing 1.

[0124] As shown in Figure 9, a clearance groove 2-7 is provided between adjacent DC power connectors. The clearance groove 2-7 includes a middle groove and end grooves located at both ends of the middle groove. The end grooves are connected to the middle groove, and the width of the end grooves is smaller than the width of the middle groove. The clearance groove 2-7 extends along the length of the DC power connector. The middle groove is located between the primary high-voltage connector 2-5 and the secondary low-voltage connector 2-6 in the same DC power connector. When the plug is inserted into the DC power connector, the power board 3-1-2 is located in the clearance groove 2-7.

[0125] During the actual assembly process, as shown in Figure 12, the dimension of the power board 3-1-2 in the direction perpendicular to the main body of the substrate is larger than the dimension of the gold finger board 3-1-1 in the direction perpendicular to the main body of the substrate. The top of the power board 3-1-2 is aligned with the top of the gold finger board 3-1-1. When the gold finger board 3-1-1 is inserted into the DC power connector, the power board 3-1-2 is located in the recess 2-7, and the magnetic core installed on the power board 3-1-2 is not in the position of the middle slot.

[0126] In this specific embodiment, by setting the clearance slot 2-7, the power board 3-1-2 can be installed in a better way to avoid interference.

[0127] In one specific embodiment, the device housing 1 may include a device base 1-1 and a detachable top cover 1-2 with an upper opening on the base 1-1. The power supply board 2 is fixed to the device base 1-1, and the DC power connector of the power supply board 2 is disposed facing the top cover 1-2. At least one side of the device housing 1 is provided with an opening, and the DC power supply device 3 is inserted into the device housing 1 through the opening.

[0128] As shown in Figure 4, the bottom of the base 1-1 is provided with a riveting stud 1-1-2, and the two sides of the base 1-1 are provided with riveting nuts 1-1-1. In the actual assembly process, the riveting stud 1-1-2 is used to fix and connect with the power supply board 2 to realize the positioning and installation of the power supply board 2; the top cover 1-2 is fixedly connected to the base 1-1 through the riveting nuts 1-1-1.

[0129] A ventilation hole 1-2-1 is provided on the side opposite to the opening in the device housing 1. The first slide is a C-shaped slide rail 1-2-2 set on the inner side wall of the top cover 1-2. The ventilation hole 1-2-1 can make airflow flow smoothly through the device housing 1, which is beneficial to the heat dissipation of the server power supply equipment.

[0130] On the other hand, the height of the DC power supply device 3 can be less than 1U. During the installation of the DC power supply device 3, it can be directly installed from the opening side of the equipment housing 1 without disassembling the equipment housing 1, which simplifies the installation and disassembly process and makes it convenient to operate.

[0131] During the installation and removal of DC power supply devices 3, generally only one DC power supply device 3 can be installed or removed at a time. When the power consumption of the server is high and a large number of DC power supply devices 3 need to be installed, if only one DC power supply device 3 can be installed at a time, it will take a long time and easily affect work efficiency. Therefore, the server power supply equipment can also include a connecting component for connecting adjacent DC power supply devices 3. The connecting component is provided with a fixing buckle for fixed connection with the DC power supply device 3. When the plug-in part is plugged into the DC power connector, the part of the DC power supply device 3 located outside the equipment shell 1 is provided with a fixing slot for engaging with the fixing buckle. The connecting component is used to connect multiple DC power supply devices 3 into a whole. At the same time, the part of the connecting component used to connect with the DC power supply device 3 is connected to the part of the DC power supply device 3 that does not need to extend into the equipment shell 1, so as not to affect the normal installation and removal of the DC power supply device 3.

[0132] In actual use, when multiple DC power supply devices 3 need to be installed, multiple DC power supply devices 3 can be connected into an integrated structure in advance through the connecting components. Then, the crossbeams 3-3-2-1 of multiple DC power supply devices 3 are simultaneously aligned with multiple first slides, and multiple DC power supply devices 3 are pushed inward at the same time, so that multiple DC power supplies move synchronously and realize the synchronous installation of multiple DC power supplies.

[0133] In this specific embodiment, by setting a connecting component to combine multiple DC power supply devices 3 into an integrated structure, the synchronous installation of multiple DC power supply devices 3 can be realized, which can effectively improve the installation efficiency of DC power supply devices 3.

[0134] In one specific embodiment, the server power supply device further includes a first controller. The device housing 1 is provided with a positioning detection element, and the DC power connector is provided with a depth detection element for detecting the insertion depth of the plug-in part. The positioning detection element is used to obtain the distance information between the part of the DC power device 3 extending into the device housing 1 and a preset position, and transmits the obtained distance information to the first controller. The depth detection element is used to obtain the insertion depth information of the plug-in part inserted into the DC power connector, and transmits the insertion depth information to the first controller. The first controller determines whether the plug-in part is inserted into the preset position based on the distance information and the insertion depth information.

[0135] Specifically, the positioning detection component can be set as a distance sensor, which can acquire the distance between the DC power supply device 3 and the target position in real time. When the distance between the DC power supply device 3 and the target position is zero, it indicates that the DC power supply device 3 has moved to the preset position. The depth detection component can be set as a pressure sensor. In actual use, when the plug is inserted into the DC power connector, the plug contacts the pressure sensor. The pressure sensor is installed at the preset insertion position of the plug. When the pressure detected by the pressure sensor changes significantly, indicating that the plug contacts the pressure sensor, it indicates that the plug has been inserted to the preset depth.

[0136] In this specific embodiment, by setting up a positioning detection component and a depth detection component, the distance information of the DC power supply device 3 extending into the equipment housing 1 and the insertion information of the plug-in part can be obtained in a timely manner, so as to provide timely feedback on the installation status of the DC power supply device 3 and facilitate the installation.

[0137] In one specific embodiment, the server power supply device further includes a display module disposed on the outside of the device housing 1 and a camera module disposed inside the device housing 1. The display modules are configured one-to-one with the DC power connectors. It should be noted that in this specific embodiment, the one-to-one configuration of display modules with DC power connectors can be configured as multiple display modules, each with a one-to-one configuration with the DC power connectors, or it can be configured as a single display module. However, the area in the display module used for displaying information is divided into different display areas, each with a one-to-one configuration with the DC power connectors. The specific configuration is determined according to the actual situation and will not be elaborated here.

[0138] The imaging module is used to acquire first image information of the DC power connector and second image information of the DC power device 3 inserted into the DC power connector, and transmits the first image information and the second image information to the first controller; the first controller obtains the insertion depth information of the insertion part in the corresponding DC power connector and the status information of the DC power connector according to the first image information and the second image information, and controls the display module to display the insertion depth information and status information.

[0139] It should be noted that the status information of the DC power connector mentioned in this specific embodiment includes: whether the DC power connector has a plug, the plug position information of the plug in the DC power connector, and whether there are impurities in the slot of the DC power connector, etc., which are determined according to the actual situation and will not be elaborated here. The plug position mentioned here includes the plug position and plug angle of the plug.

[0140] In actual use, the first controller obtains the insertion depth information of the plug part in the corresponding DC power connector and the status information of the DC power connector based on the first image information and the second image information. The display module displays the insertion depth information and the status information of the DC power connector, so that the operator can intuitively observe the insertion depth information and the status information of the DC power connector, which is conducive to timely feedback.

[0141] On the other hand, a display module can be set on an external device and connected to the first controller. The first controller controls the display module of the external device to display the insertion depth information and the status information of the DC power connector. Operators can intuitively observe the insertion depth information and the status information of the DC power connector without opening the server.

[0142] Based on the above embodiments, relevant warning devices can also be set up. In the event of an error such as the DC power supply device 3 not being properly plugged in, the warning devices can issue warning information in a timely manner so as to provide timely feedback to the operator.

[0143] In addition to the server power supply equipment described above, this disclosure also provides a server that includes the server power supply equipment provided in the above embodiments. Other structures of this server can be found in the prior art and will not be described in detail here.

[0144] In actual use, the part of the motherboard used to connect to the power supply in this specific embodiment can retain its original structure, and the server power supply equipment provided in the above embodiment can directly replace the original power supply.

[0145] In actual use, the number of server power supply devices to be installed and the number of DC power supply devices 3 to be installed in the server power supply devices can be selected according to the actual power consumption of the server to avoid the situation where the actual power supply capacity of the power module does not match the power consumption of the server.

[0146] It should also be noted that, in this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
