Description

Technical Field

[0001] This application relates to the field of server cooling technology, and in particular to a high-density immersion liquid cooler. Background Technology

[0002] Most existing immersion coolers can only accommodate one row of servers, mainly because the arrangement of multiple servers can lead to poor coolant flow or localized overheating. Multiple rows of servers can also cause uneven coolant circulation, affecting heat dissipation efficiency. Furthermore, existing immersion coolers generally lack effective mounting points for multiple rows of servers.

[0003] Therefore, since existing liquid cooling cabinets can only accommodate one row of servers, each cabinet has a certain wall thickness, and necessary passage space needs to be reserved between cabinets, the number of servers that can be installed in a unit space is limited, resulting in a low overall installation density. Utility Model Content

[0004] In order to enable the immersion liquid cooler to accommodate two rows of servers and thus increase the installation density, this application provides an immersion liquid cooler with high installation density.

[0005] The high-density immersion liquid cooler provided in this application adopts the following technical solution:

[0006] A high-density immersion cooler includes an immersion chamber with a receiving cavity and a reflux cavity inside. The receiving cavity is connected to an inlet pipe and a drain pipe. Liquid overflows from the top of the reflux cavity into the receiving cavity. The receiving cavity can accommodate two rows of servers. A reinforcing beam is installed at the bottom of the immersion chamber, located inside the receiving cavity and between the two rows of servers. The reinforcing beam has a hollow internal structure. The inlet pipe is connected to the middle of the reinforcing beam. Several drain holes are provided on both sides of the reinforcing beam along its length.

[0007] Each of the receiving cavities has a first suspension beam at its top. The first suspension beam is positioned opposite to the reinforcing beam. The mounting ears on both sides of the server are respectively hung on the first suspension beam and the top of the receiving cavity. The first suspension beam is located between the two rows of servers.

[0008] By adopting the above technical solution, the mounting ears of the two rows of servers are respectively hung on the first suspension beam and the top of the housing cavity, realizing the suspended installation of the servers and solving the installation problem of two rows of servers. While the housing volume is increased, the design of the reinforcing beam ensures the structural stability and load-bearing capacity of the enclosure. The suspended design also allows the bottom of the servers to be suspended, enabling the drain pipe to extend into the housing cavity and connect to the reinforcing beam. This allows the coolant to be evenly discharged from the bottom of the housing cavity through multiple drain holes, ensuring that each server receives sufficient cooling. Therefore, this technical solution allows two rows of servers to be accommodated in the immersion enclosure and operate stably, thereby facilitating the increase of data center installation density.

[0009] Optionally, a second suspension beam is installed on the top of the receiving cavity. The second suspension beam is parallel to the first suspension beam, and the hanging ears on both sides of the server are respectively hung on the first suspension beam and the second suspension beam.

[0010] By adopting the above technical solution, the second suspension beam provides a larger support area for the server's mounting ears, allowing the server to be stably installed in the housing cavity. At the same time, the second suspension beam also helps to further strengthen the strength of the immersion enclosure.

[0011] Optionally, the reinforcing beam is connected to at least two support columns, which are connected to the first suspension beam.

[0012] By adopting the above technical solution, the support column supports the first suspension beam, which can reduce the deformation of the first suspension beam caused by supporting multiple servers at the same time.

[0013] Optionally, the number of reflux chambers is two, and the receiving chamber is located between the two reflux chambers.

[0014] By adopting the above technical solution, the two return chambers are located on opposite sides of the receiving chamber, allowing the coolant to overflow into both chambers simultaneously after heat exchange. This bidirectional flow design ensures that the coolant is discharged more evenly from the top of the server. This reduces the occurrence of high temperatures in certain areas, stabilizes heat dissipation for each server, and ensures normal system operation.

[0015] Optionally, it also includes a housing, the immersion enclosure is installed inside the housing, the top of the housing is higher than the top of the immersion enclosure, and a wiring mechanism and a power connection module are installed on the inner peripheral wall of the housing. The wiring mechanism and the power connection module are both set higher than the immersion enclosure.

[0016] By adopting the above technical solution, signal cables are routed through a wiring mechanism installed on the inner wall of the housing. The cables connect to the power connection module, allowing power and signal lines to be arranged clearly and neatly along the inner wall of the housing, avoiding cable clutter. This makes server installation and maintenance more efficient.

[0017] Optionally, a cable hiding space is provided between the end wall of the immersion enclosure and the end wall of the housing. The wiring mechanism includes several cable guide rings. A sealing plate is provided between the top of the end wall of the immersion enclosure and the end wall of the housing. The sealing plate seals the top of the cable hiding space. The cable guide rings are installed on both the sealing plate and the top of the end wall of the housing.

[0018] By adopting the above technical solution, cables are concealed within a cable management space, resulting in a cleaner and more aesthetically pleasing system appearance and preventing messy cable distribution. The orderly guidance of cables through cable loops improves cable management and facilitates wiring and maintenance.

[0019] Optionally, the power connection module is a PDU socket, which is installed on the top of the side wall of the housing. The top of the side wall of the housing has a first through hole for passing cables and a second through hole for passing signal cables. Each row of servers is connected to the PDU socket on the same side.

[0020] By adopting the above technical solution, each row of servers can be easily connected to its corresponding PDU socket on the same side, and the proximity of the PDU socket improves the neatness of cable management. Power cables and signal cables are guided to the first and second cable entry holes respectively, avoiding signal interference caused by messy arrangement of power and signal cables. Furthermore, both signal cables and power cables can extend from the side wall of the housing for easy external connection.

[0021] Optionally, two sets of PDU sockets are installed on each of the two side walls of the housing.

[0022] By adopting the above technical solution, the two sets of PDU sockets are used in a backup manner. By adding redundancy design, it is ensured that the server can always obtain a stable power supply, thereby improving the reliability and continuity of the system.

[0023] Optionally, a pipe concealment space is provided between the side wall of the immersion tank and the side wall of the shell. The side wall of the immersion tank is provided with a mounting protrusion plate, which is arranged along the length of the immersion tank. The mounting protrusion plate seals the top of the pipe concealment space. A support portion extends from the top of the side wall of the immersion tank. The support portion is supported on the mounting protrusion plate and bolted to it. The end of the sealing plate is bolted to the mounting protrusion plate.

[0024] By adopting the above technical solution, the installation of the raised plate takes into account both the functions of shielding and supporting, simplifies the structural design, reduces the need for additional support components, simplifies the overall structure, and thus reduces the assembly difficulty.

[0025] Optionally, the side wall of the housing is provided with an inspection port, which is detachably connected to an inspection plate. Both the inlet pipe and the outlet pipe can pass through the inspection plate.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The mounting ears for the two rows of servers are respectively hung on the first suspension beam and the top of the housing cavity, enabling suspended installation of the servers and solving the installation problem for two rows of servers. While the housing volume is increased, the design of the reinforcing beam ensures the structural stability and load-bearing capacity of the enclosure. The suspended design also allows the bottom of the servers to be suspended, enabling the drain pipe to extend into the housing cavity and connect to the reinforcing beam. This allows coolant to be evenly discharged from the bottom of the housing cavity through multiple drain holes, ensuring that each server receives sufficient cooling. Therefore, this technical solution allows two rows of servers to be accommodated in an immersion enclosure and operate stably, thus facilitating increased data center server density.

[0028] 2. Two return chambers are located on opposite sides of the receiving chamber, allowing the coolant to overflow into both chambers simultaneously after heat exchange. This bidirectional flow design ensures more even coolant discharge from the top of the server, reducing the occurrence of overheating in certain areas, stabilizing heat dissipation for each server, and ensuring normal system operation.

[0029] 3. Signal cables are routed via a cabling mechanism installed on the inner wall of the housing. The cables connect to the power supply module, allowing power and signal lines to be neatly and clearly arranged along the inner wall of the housing, avoiding cable clutter. This makes server installation and maintenance more efficient.

[0030] 4. Each row of servers can be easily connected to its corresponding PDU socket on the same side, improving the neatness of cable management. Power and signal cables are guided to the first and second cable entry holes respectively, avoiding signal interference caused by messy arrangement of power and signal cables. Furthermore, both signal and power cables can extend from the side wall of the housing for easy external connection. Attached Figure Description

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0040] This application discloses a high-density immersion liquid cooler.

[0041] like Figure 1 , Figure 2 and Figure 3 The high-density immersion cooler includes a shell 1 and an immersion chamber 2. In this embodiment, the immersion chamber 2 is T-shaped; in other embodiments, it can be an inverted L-shape. The two protruding portions of the immersion chamber 2 have reflux chambers 21, and the middle portion is a receiving chamber 23. The bottom of the receiving chamber 23 is connected to an inlet pipe 24, and the bottom of the reflux chamber 21 is connected to a drain pipe 22. The receiving chamber 23 can accommodate two rows of servers. In this embodiment, only one reflux chamber 21 has a drain pipe 22 at its bottom; the other reflux chamber 21 can be sealed with a connecting plate.

[0042] A reinforcing beam 3 is installed inside the immersion enclosure 2. The reinforcing beam 3 is arranged along the length of the receiving cavity 23 and is centrally located at the bottom of the receiving cavity 23. The interior of the reinforcing beam 3 is a hollow structure, and several drainage holes 31 are equidistantly opened on both sides of the reinforcing beam 3 along its length. The liquid inlet pipe 24 is connected to the side of the reinforcing beam 3 and is connected to the middle of the side wall of the reinforcing beam 3. In other embodiments, depending on the installation method of the server, the reinforcing beam 3 may also be arranged along the width of the receiving cavity 23.

[0043] The reinforcing beam 3 has support columns 32 at both ends, and the two support columns 32 are bolted together to a first suspension beam 41. The first suspension beam 41 is parallel to the reinforcing beam 3 and is located at the top of the submersible enclosure 2. The tops of the two side walls of the submersible enclosure 2 are bolted to second suspension beams 42, and the first suspension beam 41 and the second suspension beam 42 are flush with each other.

[0044] Figure 4 and Figure 5 The immersion enclosure 2 is installed inside the housing 1. The top of the housing 1 is higher than the top of the immersion enclosure 2. The inner peripheral wall of the housing 1 is equipped with a wiring mechanism 5 and a power connection module 6. Both the wiring mechanism 5 and the power connection module 6 are set higher than the immersion enclosure 2.

[0045] like Figure 6 A pipe concealment space 11 is provided between the side wall of the submersible tank 2 and the side wall of the shell 1. The side wall of the submersible tank 2 is provided with a mounting protrusion 12, which is arranged along the length of the submersible tank 2 and seals the top of the pipe concealment space 11. An inspection port 13 is provided on the side wall of the shell 1. An inspection plate 14 is detachably connected to the inspection port 13. In this embodiment, the inspection plate 14 is connected to the shell 1 by an elastic snap-fit ​​block. In other embodiments, the inspection plate 14 can be bolted to the shell 1. The outer side wall of the return liquid chamber is opposite to the side wall of the shell 1. The inlet pipe 24 and the outlet pipe 22 can both pass through the inspection plate 14 on the same side.

[0046] A support portion 25 extends from the top of the side wall of the immersion chamber 2 (i.e., the top of the outer side wall of the reflux chamber 21). The support portion 25 is arranged along the length direction of the immersion chamber 2 and is supported on the mounting protrusion 12 and bolted together. A sealing plate 15 is bolted to the same end of the two mounting protrusions 12. The sealing plate 15 is arranged along the width direction of the housing 1.

[0047] like Figure 7A cable hiding space 16 is left between the end wall of the submersible enclosure 2 and the end wall of the housing 1. The wiring mechanism 5 includes several cable guide rings 51. The sealing plate 15 seals the top of the cable hiding space 16. Cable guide rings 51 are installed on the top of both the sealing plate 15 and the end wall of the housing 1. On the sealing plate 15, several cable guide rings 51 are arranged in several columns and several rows at equal intervals. On the inner wall of the end of the housing 1, several rows of cable guide rings 51 are arranged in several columns and several rows at equal intervals.

[0048] The power connection module 6 is a PDU socket 61, which is installed on the top of the side wall of the housing 1. The top of the side wall of the housing 1 has a first through hole 17 for cable routing and a second through hole 18 for signal cable routing. Each row of servers is connected to the PDU socket 61 on the same side. Two sets of PDU sockets 61 are installed on each of the two side walls of the housing 1. Two first through holes 17 and two through holes 18 are provided on each of the two side walls of the housing 1.

[0049] Both second wiring holes 18 are centrally located in the middle of the side wall of the housing 1. The second wiring holes 18 are located between the two sets of PDU sockets 61. The two first wiring holes 17 are located at one end of the side wall of the housing 1, that is, the PDU sockets 61 are located between the two first wiring holes 17.

[0050] In other embodiments, the wiring mechanism 5 may be a cable guide plate, and the power connection module 6 may be an IPDU.

[0051] The implementation principle of this application embodiment is as follows: the mounting ears of the two rows of servers are respectively hung on the first suspension beam 41 and the top of the receiving cavity 23, realizing the suspended installation of the servers and solving the installation problem of two rows of servers. With the increased volume of the receiving cavity 23, the design of the reinforcing beam 3 ensures the structural stability and load-bearing capacity of the enclosure. The suspended design also allows the bottom of the servers to be suspended, enabling the drain pipe 22 to extend into the receiving cavity 23 and connect to the reinforcing beam 3. This allows the coolant to be evenly discharged from the bottom of the receiving cavity 23 through multiple drain holes 31, ensuring that each server receives sufficient cooling. Therefore, this technical solution allows two rows of servers to be accommodated in the immersion enclosure 2, and the two rows of servers can operate stably, thereby improving the installed capacity of the data center.

[0052] Each row of servers can be easily connected to its corresponding PDU socket 61 and cable guide ring 51 on the same side. Proximity to the PDU socket 61 improves the neatness of cable management. Proximity to the cable guide ring 51 improves the neatness of signal cable management. Power cables and signal cables are guided to the first cable pass-through hole 17 and the second cable pass-through hole 18 respectively, avoiding signal interference caused by messy arrangement of power and signal cables. Furthermore, both signal and power cables can extend from the side wall of the housing 1 for easy external connection. Signal cables are routed through the cable guide ring 51 installed on the inner peripheral wall of the housing 1, and the cables connect to the PDU socket 61, allowing power and signal cables to be clearly and neatly arranged along the inner wall of the housing 1, avoiding cable clutter. This makes server installation and maintenance more efficient.

[0053] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
