Abstract
Description
Technical Field
[0001] This application relates to the field of server cooling technology, and in particular to a compact immersion liquid cooler. Background Technology
[0002] With the improvement of server performance, liquid cooling technology has gradually become one of the mainstream heat dissipation methods, especially for high-density server clusters, where liquid cooling can dissipate heat more efficiently. However, in existing liquid cooling systems, uneven distribution of coolant often leads to poor heat dissipation in some areas, thus affecting the overall operating efficiency and stability of the server.
[0003] In addition, the electrical connections of existing servers mostly rely on wire connections, especially in high-density installation environments. The wiring is complex and takes up a lot of space, so the cabinet usually needs to have enough installation space inside, which makes the existing liquid-cooled cabinets take up a lot of space. Utility Model Content
[0004] In order to optimize the coolant distribution of the liquid cooling system while making the internal structure of the liquid cooler more compact and reducing the space occupied by the liquid cooler, this application provides a compact immersion liquid cooler.
[0005] The compact immersion liquid cooler provided in this application adopts the following technical solution:
[0006] A compact immersion liquid cooler includes an immersion chamber. A flow divider is installed at the bottom of the immersion chamber. The flow divider has several flow divider holes and a recessed mounting groove. A stacked busbar is installed in the mounting groove. The flow divider, the bottom wall of the immersion chamber, and the inner side wall of the immersion chamber enclose a liquid inlet space. A drain pipe is connected to the reflux chamber of the immersion chamber, and a liquid inlet pipe is connected to the liquid inlet space.
[0007] By adopting the above technical solution, the multiple distribution holes on the distribution plate allow the coolant to overflow evenly to each cooling area of the server. Through the uniform distribution of coolant, the problem of insufficient heat dissipation in local areas is avoided, and the overall heat dissipation efficiency of the server is improved.
[0008] Furthermore, by installing stacked busbars in the mounting grooves of the distributor plate, the use of cabling is reduced and the electrical connection method is simplified. Therefore, there is no need to reserve space for cabling, which can appropriately reduce the space occupied by the liquid cooling cabinet.
[0009] Meanwhile, by using the mounting groove formed by the distribution plate to embed the stacked busbars, the cooling and electrical connection functions are integrated on the distribution plate, eliminating the need for other connection plates for mounting the stacked busbars. This makes the entire liquid cooler cabinet design more compact and helps to further reduce the space occupied by the liquid cooler cabinet.
[0010] Optionally, a stiffening plate is installed in the reflux chamber of the immersion tank, the stiffening plate is located above the drain pipe, and a diversion port is opened on the stiffening plate.
[0011] By adopting the above technical solution, the installation of the stiffening plate provides an additional support structure, which can enhance the overall strength of the immersion tank, especially the return cavity, and reduce the possibility of dents and deformations in the return cavity caused by impacts to the immersion tank. Secondly, the diversion port can be connected to a diversion pipe, and connecting the diversion pipe to the drain pipe at the same time can speed up the drainage process.
[0012] Optionally, the diverter plate has support plates extending downward on both sides, and the support plates and the outer bottom wall of the mounting groove are supported on the inner bottom wall of the immersion chamber.
[0013] By adopting the above technical solution, the mounting groove not only serves as the installation space for the stacked busbars but also supports the distributor plate, allowing for more stable installation of the distributor plate within the immersion enclosure. Furthermore, when connecting the server and pressing it down to connect it to the stacked busbars, the mounting groove, supported by the immersion enclosure, reduces the likelihood of distributor plate deformation.
[0014] Optionally, the mounting groove is provided along the length of the flow divider and extends to the end of the flow divider. The end wall of the immersion tank has two liquid inlets. The liquid inlet pipe is connected to the two liquid inlets. The liquid inlets are located below the flow divider, and the two liquid inlets are respectively located on both sides of the mounting groove.
[0015] By adopting the above technical solution, the mounting groove design allows for the installation of more stacked busbars, thereby enabling the installation of more servers within the immersion enclosure. However, this mounting groove design divides the liquid inlet space into two spaces, thus requiring two liquid inlets to simultaneously drain liquid into both spaces, ensuring even distribution of coolant while accommodating more servers.
[0016] Optionally, the end wall of the immersion tank is provided with a discharge port, and the discharge port is connected to a discharge pipe.
[0017] By adopting the above technical solution, when the cabinet needs maintenance, the coolant inside the cabinet can be completely drained through the drain pipe, making maintenance convenient.
[0018] Optionally, the top front side and both sides of the immersion enclosure have protrusions extending outwards. A terminal block is installed in the protrusion, and the cable can pass through the bottom of the protrusion. A front sealing plate is provided on the front side of the immersion enclosure. The protrusion on the front side of the immersion enclosure is supported on the front sealing plate. Support columns are installed on both sides of the front sealing plate. The support columns, the front sealing plate, and the immersion enclosure together enclose a cable hiding space. The support columns have cable insertion holes.
[0019] Both ends of the immersion box are provided with end sealing plates. The protrusion at the end of the immersion box is supported on the end sealing plates. The support column, the end sealing plates and the immersion box together enclose the end tube storage space.
[0020] The rear side of the immersion box is provided with a rear sealing plate, and the top wall of the reflux chamber of the immersion box is supported on the rear sealing plate. The support, the end sealing plate, the immersion box and the rear sealing plate together enclose the end pipe storage space, and the rear sealing plate is provided with multiple pipe through ports.
[0021] By adopting the above technical solution, signal transmission cables can be centrally housed within the protruding section, resulting in a clearer and neater internal layout of the liquid cooler. Furthermore, cable maintenance and management become more convenient. The cable concealment space provides a dedicated area for storing and hiding cables, ensuring not only the cleanliness of the liquid cooler's interior but also effectively preventing potential safety hazards caused by exposed cables.
[0022] The concealed pipe space at the end effectively hides the drain pipe, inlet pipe, and outlet pipe, making the liquid cooler look simpler and reducing the impact of exposed pipes on operation and maintenance.
[0023] The protrusion, front panel, rear panel, and end panel form the outer wall of the cabinet. At the same time, the protrusion and the front panel form a cable concealment space, and the protrusion and the end panel and rear panel form a pipe concealment space, which optimizes the use of internal space and improves the compactness of the cabinet.
[0024] Optionally, a number of limiting connecting blocks are installed on the periphery of the immersion tank, and the end sealing plate and the rear end are bolted to the corresponding limiting connecting blocks.
[0025] By adopting the above technical solution, the limiting block facilitates the connection between the end sealing plate and the rear sealing plate and the submersible box, and the limiting connecting block abutting against the end sealing plate and the rear sealing plate helps to ensure sufficient space for pipe storage.
[0026] Optionally, the bottom of the immersion enclosure is connected to a mounting bracket, the mounting bracket is equipped with rollers, and several positioning guide rails are provided on both sides of the immersion enclosure, the side of the server can be inserted into the positioning guide rails.
[0027] By adopting the above technical solution, the roller design at the bottom of the mounting bracket allows the entire immersion liquid cooler to be moved easily. The positioning guide rail design allows the server to be installed by insertion; after the side of the server is inserted into the guide rail, it can be stably fixed in the immersion enclosure.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. The multiple distribution holes on the distribution plate allow the coolant to overflow evenly to all cooling areas of the server. Through uniform coolant distribution, the problem of insufficient heat dissipation in local areas is avoided, and the overall heat dissipation efficiency of the server is improved.
[0030] 2. By installing the stacked busbar in the mounting groove of the distributor plate, the use of cabling is reduced and the electrical connection method is simplified. Therefore, there is no need to reserve cabling space, which can appropriately reduce the space occupied by the liquid cooling cabinet.
[0031] 3. The mounting grooves formed by the manifold plate are used to embed the stacked busbars, integrating cooling and electrical connection functions on the manifold plate. There is no need to set up other connection plates for mounting the stacked busbars, which makes the entire liquid cooling cabinet design more compact and helps to further reduce the space occupied by the liquid cooling cabinet.
[0032] 4. The mounting groove not only serves as the installation space for the stacked busbars but also supports the distributor plate, allowing for more stable installation within the immersion enclosure. Furthermore, when connecting the server and pressing it down to connect it to the stacked busbars, the mounting groove's support on the immersion enclosure reduces the likelihood of distributor plate deformation.
[0033] 5. Signal transmission cables can be centrally housed within the protruding section, resulting in a clearer and neater internal layout for the liquid cooler. Furthermore, cable maintenance and management become more convenient. The concealed cable space provides a dedicated area for storing and hiding cables, ensuring not only the cleanliness of the liquid cooler's interior but also effectively preventing potential safety hazards caused by exposed cables. The end-pipe concealment space effectively hides the drain pipe, inlet pipe, and outlet pipe, resulting in a cleaner appearance for the liquid cooler and reducing the impact of exposed pipes on operation and maintenance.
[0034] 6. The protrusion, front panel, rear panel, and end panel form the outer wall of the cabinet. At the same time, the protrusion and the front panel form a cable concealment space, and the protrusion and the end panel and rear panel form a pipe concealment space, which optimizes the use of internal space and improves the compactness of the cabinet.

[0043] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0044] This application discloses a compact immersion liquid cooler.
[0045] like Figure 1 and Figure 2The compact immersion liquid cooler includes an immersion chamber 1, with a protruding rear side forming a reflux chamber 11 inside. Protrusions 12 extend from the front of the top and from both sides of the top of the immersion chamber 1, connecting with protrusions 12 at the ends of the immersion chamber 1. The protrusions 12 at the ends of the immersion chamber 1 connect with the reflux chamber 11. A flow divider 2 is installed at the bottom of the immersion chamber 1, adapting to the immersion chamber 1, and has several flow divider holes 21. The flow divider 2, along with the inner bottom and side walls of the immersion chamber 1, encloses a liquid inlet space 13.
[0046] The diverter plate 2 has a recessed mounting groove 22, which is symmetrically arranged about the center line of the diverter plate 2 along its length. The mounting groove 22 extends along the length of the diverter plate 2 to the end of the diverter plate 2. Support plates 23 extend downward from both sides of the diverter plate 2. The support plates 23 and the outer bottom wall of the mounting groove 22 are supported on the inner bottom wall of the immersion housing 1. A stacked busbar 24 is installed in the mounting groove 22. In this embodiment, the stacked busbar 24 is a copper busbar (BUSBAR).
[0047] Two liquid inlets 14 are provided at the bottom of one end wall of the submersible tank 1, and two discharge outlets 15 are provided at the bottom of the other end wall of the submersible tank 1. The liquid inlets 14 are connected to an inlet pipe 31, and the discharge outlets 15 are connected to a discharge pipe 32. A drain pipe 33 is connected to the bottom of the return chamber 11 of the submersible tank 1. A stiffening plate 16 is installed inside the return chamber 11 of the submersible tank 1. The stiffening plate 16 is located above the drain pipe 33, and a diversion port 161 is provided on the stiffening plate 16. A diversion pipe can be connected to the diversion port 161 and then connected to the drain pipe 33. Several positioning guide rails 17 are provided on both sides of the submersible tank 1, and the positioning guide rails 17 are arranged equidistantly along the length of the submersible tank 1.
[0048] like Figure 3 The two sides of the submersible chamber 1 are positioned by guide rails 17, and the bottom of the submersible chamber 1 is bolted to a mounting bracket 4. The bottom of the mounting bracket 4 is rotatably connected to a roller 41.
[0049] like Figure 3 , Figure 4 and Figure 5 A terminal block 18 is installed inside the protrusion 12, and cables can pass through the bottom of the protrusion 12. A front end plate 61 is provided on the front side of the submersible enclosure 1, and the protrusion 12 on the front side of the submersible enclosure 1 is supported on the front end plate 61. Support columns 62 are bolted to both sides of the front end plate 61, and the front end plate 61 is bolted to the mounting bracket 4.
[0050] like Figure 3 and Figure 6The support column 62, the front sealing plate 61 and the submersible box 1 together enclose the cable storage space 65, and the support column 62 has a cable threading port 621.
[0051] like Figure 6 and Figure 7 Both ends of the submersible enclosure 1 are provided with end sealing plates 63. The protrusions 12 at the ends of the submersible enclosure 1 are supported on the end sealing plates 63. The end sealing plates 63 are bolted to the limiting connecting blocks 5. The support column 62, the end sealing plates 63, the submersible enclosure 1 and the support frame together enclose the end pipe storage space 66.
[0052] like Figure 4 and Figure 6 The rear side of the submersible tank 1 is provided with a rear sealing plate 64, which is bolted to the limiting connecting block 5. The top wall of the reflux chamber 11 of the submersible tank 1 is supported on the rear sealing plate 64. The support column 62, the end sealing plate 63, the submersible tank 1 and the rear sealing plate 64 together enclose the end pipe storage space 66. The rear sealing plate 64 has three through-holes 641, which correspond to the inlet pipe 31, the outlet pipe 32 and the drain pipe 33 respectively.
[0053] The implementation principle of this application embodiment is as follows: Several diversion holes 21 on the diversion plate 2 allow the coolant to overflow evenly to each cooling area of the server. This uniform coolant distribution avoids insufficient heat dissipation in localized areas, improving the overall heat dissipation efficiency of the server. By installing the stacked busbar 24 in the mounting groove 22 of the diversion plate 2, the use of cabling is reduced, simplifying the electrical connection method. Therefore, there is no need to reserve space for cabling, which can appropriately reduce the space occupied by the liquid-cooled cabinet. The stacked busbar 24 is embedded in the mounting groove 22 formed by the diversion plate 2, integrating cooling and electrical connection functions onto the diversion plate 2. No other connecting plates for installing the stacked busbar 24 are required, making the entire liquid-cooled cabinet design more compact and further reducing the space occupied by the liquid-cooled cabinet.
[0054] Furthermore, the signal transmission cables can be centrally housed within the protrusion 12, making the internal layout of the liquid cooler clearer and neater. In addition, cable maintenance and management become more convenient. The cable concealment space 65 provides a dedicated area for storing and hiding cables, ensuring not only the cleanliness of the liquid cooler's interior but also effectively preventing potential safety hazards caused by exposed cables.
[0055] The end-mounted pipe space 66 effectively conceals the drain pipe 33, inlet pipe 31, and outlet pipe 32, making the liquid cooler's appearance more concise and reducing the impact of exposed pipes on operation and maintenance.
[0056] The protrusion 12, the front side panel 61, the rear side panel 64, and the end panel 63 form the outer wall of the cabinet. At the same time, the protrusion 12 and the front side panel 61 form a cable hiding space 65, and the protrusion 12, the end panel 63, and the rear side panel 64 form a pipe hiding space 66, which optimizes the use of internal space and improves the compactness of the cabinet.
[0057] 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.
