[0031] See again Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 The immersion liquid cooling server and liquid cooling system provided by the embodiment of the present invention include several 1U server units; each of the several 1U server units includes several 1U servers 100, several power modules 200 and a power backplane 300; the bottom end of each of the 1U servers 100 and the bottom end of each of the power modules 200 in the several 1U server units are connected to the power backplane 300, and the 1U server 100 and the power module 200 are arranged adjacent to each other; a gap is provided between the bottom of the several 1U servers and the several power modules and the power backplane; each of the 1U servers 100 in the several 1U server units includes a chassis 110, an upper panel 130 and a hard disk assembly 140; the upper panel 130 is fixed to the top of the chassis 110, and the hard disk assembly 140 is arranged adjacent to the upper panel 130; the chassis 110 contains cooling liquid.

[0032] In this embodiment, the bottom end of the power module 200 is electrically connected to the power backplane 300 to provide power to the power backplane 300. The 1U server 100 is connected to the power backplane 300 through the power interface at the bottom to obtain electrical energy, wherein the 1U server 100 is connected to the power backplane 300 through the power interface, specifically the power interface is connected to the output line of the power module 200 through the power backplane 300. Since the height of the 1U server 100 is only 1.75 inches (about 4.45 cm), the space inside the 1U server 100 is extremely limited. The power module 200 is set outside the 1U server 100 and connected through the power backplane 300 at the bottom, which can maximize the use of limited space and avoid wasting the internal space of the 1U server 100. The chassis 110 of the 1U server 100 is not provided with a top cover, which is convenient for technicians to operate and maintain the 1U server 100, and is also conducive to improving the heat dissipation effect. In addition, the power module 200 is one of the components that generates the most heat in the liquid cooling system. Placing it outside the 1U server 100 can reduce the heat load on the internal space of the 1U server 100, which is beneficial to the heat dissipation of other components inside the 1U server 100, thereby maintaining the stable operation of the 1U server 100 system.

[0033] In one embodiment, if Figure 3 As shown, the upper panel 130 includes an upper panel body 131, and the upper panel body 131 is provided with a first functional area and a second functional area. The first functional area is provided with an Mgt RJ45 network port 1311, an OCP3.0 interface 1312, an HHHL PCIe Slot plug 1313, several USB interfaces 1314, a VGA interface 1315, a power button 1316, a display digital tube 1317, and several EDSFF E1.SSSD slots 1318;

[0034] The Mgt RJ45 network port 1311, the OCP3.0 interface 1312, the HHHL PCIe Slot pin 1313, the multiple USB interfaces 1314, the VGA interface 1315, the power button 1316, and the display digital tube 1317 are all arranged around the outer edge of the upper panel body; the multiple EDSFF E1.SSSD slots 1318 are arranged in the second functional area.

[0035] In this embodiment, Mgt RJ45 (Management Registered Jack 45) refers to an Ethernet interface on the server used for remote management and control, which is connected to other network devices through an RJ45 connector. OCP3.0 (Open Compute Project) refers to the third edition interface specification of the Open Compute Project. Specifically, OCP3.0 in the embodiment of this application refers to a network card interface that complies with the OCP 3.0 specification. HHHL PCIe Slot (Half-Height Half-Length PCI Express Slot) refers to a hardware device with a height and length that is only half the standard size pin, which is used to connect to the high-speed serial computer expansion bus standard. USB (Universal Serial Bus) interface refers to an interface for communication, connection and data transmission. VGA (Video Graphics Array) interface refers to an interface standard mainly used to connect a 1U server 100 and a display device (such as a monitor, projector, etc.) to realize the transmission of video signals. The EDSFFE1.S SSD (Enterprise & Data Center SSD Form Factor E1.S) slot is primarily used in data centers and enterprise-class servers. It supports high-speed data transmission and achieves higher storage capacity within a limited space.

[0036] Specifically, in this embodiment, the upper panel body 131 is equipped with one Mgt RJ45 management network port, one OCP3.0 interface 1312, one HHHL PCIe slot latch 1313, two USB ports 1314, one VGA port 1315, a power button 1316, a display 1317 (dual digital display), and eight EDSFF E1.S SSD slots 1318. The eight EDSFF E1.S SSD slots 1318 can be expanded by one OCP3.0 and one PCIe slot. By selecting high-performance E1.S hard drives, fewer hard drives can meet computing power requirements, leaving more space for other interface designs. The more rational layout of the various interfaces on the upper panel 130, combined with the hard drive backplane 141 design, reduces the space occupied by hard drives within the 1U server 100, making the internal layout of the 1U server 100 more compact and saving internal space. At the same time, all interfaces are designed on the upper panel 130 , making it more convenient for operation and maintenance personnel to operate and manage the 1U server 100 .

[0037] It should be noted that the number of various interfaces, buttons and display digital tubes set on the upper panel body 131 is only used to illustrate this embodiment. In this embodiment, the specific number of the various interfaces, buttons and display digital tubes involved is not limited and can be set according to actual needs.

[0038] In one embodiment, if Figure 2 as well as Figure 3 As shown, the upper panel 130 also includes a first hanging ring 132, a handle 133 and a plurality of liquid holes 134; the first hanging ring 132 is arranged on both sides of the upper panel body 131; the handle 133 is arranged in the middle of the upper panel body 131; the plurality of liquid holes 134 are used to pass the cooling liquid.

[0039] In this embodiment, maintenance personnel can pull out the 1U server 100 using the first lifting ring 132 or directly using the handle 133, greatly facilitating maintenance and operation of the 1U server 100. The upper panel 130 is provided with a plurality of liquid holes 134 to facilitate the flow of coolant, reducing the resistance of the coolant through the 1U server 100. This allows more coolant to flow through the interior of the 1U server 100 with less resistance, cooling the internal components of the 1U server 100 and improving the heat dissipation efficiency of the 1U server 100.

[0040] In one embodiment, if Figure 4 As shown, the 1U server also includes a motherboard 120; the motherboard 120 is provided with a plurality of CPUs 121, a plurality of memory DIMM slots 122, a first PCIe CONN 123, a riser card 124, an OCP network card interface 125 and a plurality of M.2 slots 126; the plurality of CPUs 121 are arranged on the motherboard 120 at intervals on the horizontal direction and are connected to the plurality of memory DIMM slots 122 and the first PCIe CONN 123; the plurality of memory DIMM slots 122 are evenly arranged on both sides of the plurality of CPUs 121; the riser card 124 is connected to the first PCIe CONN 123; the OCP network card interface 125 is arranged above the plurality of M.2 slots 126.

[0041] In this embodiment, by horizontally disposing CPU 121 (Central Processing Unit) on motherboard 120 and evenly distributing memory DIMM (Dual-Inline Memory Module) slots on both sides of each CPU 121 (shown as a schematic diagram and not representing a specific number), dual-channel or multi-channel memory configuration can be more easily implemented and helps achieve balanced load distribution. In addition, due to the close physical distance between CPU 121 and memory, the liquid cooling system can more effectively remove the heat generated by these components, improving the heat removal efficiency and maintaining stable system operation.

[0042] The CPU 121 is connected to the memory DIMM and the first PCIe CONN (Peripheral Component Interconnect Express Connector) signal through the PCB (Printed Circuit Board) of the motherboard 120 and communicates. Specifically, the number of PCIe CONNs varies depending on the 1U server 100 platform. For example, in the Intel Whiltley platform, a single CPU has a total of 80 PCIe Lanes (Peripheral Component Interconnect Express Lanes), of which 48 are on the north side. If a PCIe CONN that supports 8 lane connections is used, 6 PCIe CONNs can be supported; if a PCIe CONN that supports 8 lane connections is used, 2 PCIe CONNs can be supported. The first PCIe CONN 123 can be docked with a riser card 124 with a cable to achieve flexible expansion of PCIe devices, and can also be connected to the backplane.

[0043] The motherboard 120 is also provided with two M.2 slots, which are compatible with PCIe signals and SATA (Serial Advanced Technology Attachment, hard disk interface specification) signals. They can support NVMe SSD (Non-Volatile Memory Express Solid State Drive, non-volatile memory host controller interface specification solid state drive) and SATA SSD (Serial Advanced Technology Attachment Solid State Drive, solid state drive using SATA interface), which helps to improve system performance, enhance system scalability, and improve system stability and compatibility.

[0044] It should be noted that the two M.2 slots provided on the motherboard 120 are only used to illustrate this embodiment. In this embodiment, the specific number of M.2 slots is not limited and can be set according to actual needs.

[0045] In one embodiment, if Figure 2 as well as Figure 4 As shown, a first Power CONN 127 is provided on the mainboard 120 near the bottom of the chassis; a first positioning pin 111 and a second positioning pin 112 are provided on the bottom of the chassis 110 .

[0046] In this embodiment, the first Power CONN 127 provided on the mainboard 120 is used to connect to the power backplane 300 to provide the power required for the normal operation of the mainboard 120. The first Power CONN 127 is provided on the mainboard 120 in an area close to the bottom of the chassis. The power supply is connected to the power backplane 300 through the first Power CONN 127, thereby avoiding the introduction of power lines and busbars, reducing the design risk of the liquid cooling system, and improving the reliability of the power supply. The bottom of the chassis 110 is provided with a first positioning pin 111 and a second positioning pin 112 to facilitate positioning of the 1U server 100 when it is inserted into the liquid cooling box. In addition, the bottom of the chassis 110 of the 1U server 100 is also provided with a plurality of liquid holes (not shown in the figure) to facilitate the flow of cooling liquid, thereby achieving a better heat dissipation effect.

[0047] In one embodiment, if Figure 4 As shown, the hard disk assembly 140 includes a hard disk, a hard disk backplane 141, an EDSFF CONN 142 and a second PCIe CONN; the hard disk is connected to the multiple M.2 slots 126; the EDSFF CONN 142 and the second PCIe CONN are both located on the hard disk backplane 141, wherein the second PCIe CONN is connected to the first PCIe CONN 123.

[0048] In this embodiment, the hard drive is not shown due to viewing angles. In addition to the EDSFF CONN (Enterprise and Data center SSD Form Factor, a connector for enterprise-class and data center-class solid-state drives), the hard drive backplane 141 is also provided with a PCIe CONN of the same type (i.e., a second PCIe CONN, not shown) that is connected to the PCIe CONN (i.e., the first PCIe CONN 123) of the motherboard 120. Therefore, the first PCIe CONN 123 on the motherboard 120 can be connected to different hard drive backplanes 141, thereby achieving flexible configuration of the storage capacity of the 1U server 100. The number of second PCIe CONNs on the hard drive backplane 141 varies depending on the number of E1.S hard drives supported (e.g., if an E1.S hard drive supports 4 PCIe Lanes, a PCIe CONN supporting 8 Lane connections is placed on the backplane, then two E1.S hard drives can be supported), thereby reducing costs and energy consumption and effectively improving storage density and capacity.

[0049] In one embodiment, if Figure 5 As shown, the power module 200 includes a power module body 210, a second hanging ring 220, a power interface 230, a third positioning pin 240 and a second Power CONN 250; the second hanging ring 220 and the power interface 230 are both arranged at the top of the power module body 210, wherein the power interface 230 is used to connect to the power wiring; the third positioning pin 240 and the second Power CONN 250 are both arranged at the bottom of the power module body 210; the second Power CONN 250 is connected to the power backplane 300; and the outer wall of the power module body 210 is provided with a plurality of honeycomb holes.

[0050] In this embodiment, since the height of the liquid cooling box does not exceed 1 meter, the server adopts a 1U highly modular design, making the server depth no more than 0.5 meters. Therefore, operation and maintenance personnel can easily remove the power module 200 from the liquid cooling box using the second lifting ring 220. In addition, the 1U server 100 can also be removed from the liquid cooling box using the handle 133 without the need for overhead crane equipment, greatly simplifying operation and maintenance and saving operation and maintenance costs.

[0051] The top of the power module body 210 is provided with a power interface 230 to facilitate power wiring; the bottom is provided with a second Power CONN 250 for connecting to the power backplane 300, so that the power cord does not need to be wrapped around the bottom of the liquid cooling box, which is convenient for operation and maintenance. The provision of the third locating pin 240 prevents misalignment when the power module 200 is inserted into the liquid cooling box. Since a number of honeycomb holes (not shown in the figure) are provided on the outer wall of the power module body 210, the effective contact area between the power module 200 and the coolant can be increased, which is beneficial to improving the overall heat dissipation efficiency.

[0052] In one embodiment, if Figure 6 As shown, the power backplane 300 is provided with a reinforcement frame, a first positioning hole 310, a second positioning hole 320, a third positioning hole 330, a third Power CONN 340 and a fourth Power CONN 350; the reinforcement frame is used to fix the power backplane 300; the first positioning pin 111 is aligned with the first positioning hole 310, the second positioning pin 112 is aligned with the second positioning hole 320, and the third positioning pin 240 is aligned with the third positioning hole 330; the first Power CONN 127 is connected to the third Power CONN 340, and the second Power CONN 250 is connected to the fourth Power CONN 350.

[0053] In this embodiment, holes are opened on the power backplane 300 (not shown in the figure) to avoid the internal wiring of the PCB, and the coolant circulates through the holes, which can achieve an effective heat dissipation effect. By setting a reinforcing frame (not shown in the figure), the power backplane 300 can be effectively fixed to the bottom of the liquid cooling box. In addition, the power backplane 300 can appropriately increase the opening rate on the power backplane 300 according to actual needs. The increase in the opening rate can improve the circulation of the coolant and accelerate the heat dissipation rate, thereby effectively reducing the operating temperature of the power backplane 300. By matching the first positioning pin 111 with the first positioning hole 310, the second positioning pin 112 with the second positioning hole 320, and the third positioning pin 240 with the third positioning hole 330, the accuracy of the insertion and positioning of the 1U server 100 and the power module 200 with the power backplane 300 can be effectively improved.

[0054] The second Power CONN 250 on the power module body 210 is connected to the fourth Power CONN 350 on the power backplane 300 to provide power to the power backplane 300. The first Power CONN 127 on the mainboard 120 is connected to the third Power CONN 340 on the power backplane 300 to obtain power.

[0055] In one embodiment, a partition plate is further included. The partition plate is provided between the 1U server 100 and the power module 200 and is used to fix the 1U server 100 and the power module 200 .

[0056] In this embodiment, the 1U server 100 power module 200 is secured by a partition plate (not shown in the figure), which can improve the overall strength of the liquid cooling system and provide greater stability when the 1U server 100 power module 200 is placed in the liquid cooling box. Because the 1U server 100 and power module 200 generate a large amount of heat during operation, a plurality of honeycomb holes are also provided on the partition plate. The honeycomb hole design allows the coolant to circulate and fully contact the 1U server 100 and power module 200, effectively dissipating heat and achieving a good heat dissipation effect.

[0057] The present invention also provides a liquid cooling system. Figure 7 As shown, the liquid cooling system includes an immersion liquid cooling server as in any of the aforementioned embodiments, and also includes a liquid cooling box 400. The immersion liquid cooling server is arranged in the liquid cooling box 400.
