Description

Technical Field

[0001] This disclosure relates to the field of liquid cooling technology, and in particular to a liquid cooling distribution unit and cabinet. Background Technology

[0002] The cooling distribution unit (CDU) internally includes primary and secondary piping. The primary piping connects to the liquid cooling source, while the secondary piping supplies coolant to the liquid cooling plates in electronic devices. The coolant in the primary and secondary piping exchanges heat within the CDU.

[0003] In related technologies, a liquid-cooled distribution unit includes a main body and an outer frame. The main body includes primary and secondary piping, and a first liquid-cooled quick-connect fitting for connecting the primary and secondary piping to external systems. The outer frame is equipped with a second liquid-cooled quick-connect fitting, which connects to external piping, such as corresponding piping connecting an external liquid cooling source and corresponding piping connecting an external liquid cooling plate. When the first and second liquid-cooled quick-connect fittings are connected, the primary and secondary piping are connected to the external piping.

[0004] However, the connection resistance was significant during the docking of the first and second liquid-cooled quick connectors, making it difficult for a single person to complete the operation. Summary of the Invention

[0005] This disclosure provides a liquid-cooled distribution unit and a cabinet. The liquid-cooled distribution unit is equipped with a magnetic component, and the magnetic force generated by the magnetic component can offset part of the docking resistance of the liquid-cooled quick connector, thereby assisting maintenance personnel in docking the liquid-cooled quick connector. The technical solutions of the liquid-cooled distribution unit and the cabinet are described below.

[0006] In a first aspect, this disclosure provides a cooling distribution unit (CDU). The cooling distribution unit includes a main body, an outer frame, a first liquid cooling quick connector, a second liquid cooling quick connector, a first magnetic component, and a second magnetic component. The first liquid cooling quick connector is fixed to the main body, and the second liquid cooling quick connector is fixed to the outer frame. The outer frame and the cooling distribution unit slide relative to each other along a first direction. The first liquid cooling quick connector is used to engage with the second liquid cooling quick connector, and the engagement direction of the first and second liquid cooling quick connectors is the first direction. The first magnetic component is fixed to the main body, and the second magnetic component is fixed to the outer frame. The first and second magnetic components are arranged opposite each other in the first direction, and a magnetic attraction force is generated between the first and second magnetic components.

[0007] The technical solution provided in this disclosure, during the process of connecting the first liquid-cooled quick connector and the second liquid-cooled quick connector, uses the magnetic attraction force generated between the first magnetic component and the second magnetic component to drive the first liquid-cooled quick connector and the second liquid-cooled quick connector to approach each other, which can offset part or all of the connection resistance, thereby helping maintenance personnel to connect the first liquid-cooled quick connector and the second liquid-cooled quick connector.

[0008] In one implementation, the outer frame includes a first end plate, and the liquid-cooled distribution unit body includes a second end plate. The second end plate and the first end plate are arranged opposite each other along a first direction. A first liquid-cooled quick-connect fitting and a first magnetic element are disposed on the second end plate, and a second liquid-cooled quick-connect fitting and a second magnetic element are disposed on the first end plate. Thus, the magnetic attraction force generated between the first and second magnetic elements drives the first and second liquid-cooled quick-connect fittings to approach each other, thereby offsetting some or all of the docking resistance.

[0009] In one implementation, the first magnetic component is fixed to the second end plate and arranged side by side with the first liquid-cooled quick connector.

[0010] In one implementation, the first magnetic component and the second end plate are the same part, with the second end plate made of a magnetic material and forming the first magnetic component. This eliminates the need to modify the structure of the main body of the liquid-cooled distribution unit; only the material of the second end plate needs to be modified. The second end plate and the second magnetic component are used to generate a magnetic attraction force.

[0011] In one implementation, the second magnetic component is fixed to the first end plate and arranged side by side with the second liquid-cooled quick connector.

[0012] In one implementation, the second magnetic component and the first end plate are the same part, with the first end plate made of a magnetic material and forming the second magnetic component. This eliminates the need to modify the structure of the outer frame; only the material of the first end plate needs to be changed. The first end plate and the first magnetic component are used to generate magnetic attraction.

[0013] In one implementation, the first magnetic component and the first liquid-cooled quick connector are the same part, with the first liquid-cooled quick connector being made of a magnetic material and forming the first magnetic component. Similarly, the second magnetic component and the second liquid-cooled quick connector are the same part, with the second liquid-cooled quick connector being made of a magnetic material and forming the second magnetic component. This way, only the materials of the first and second liquid-cooled quick connectors need to be modified, without requiring any changes to the other structural designs of the liquid-cooled distribution unit.

[0014] In one implementation, both the first and second magnetic components are magnets. This results in a larger magnetic force between the first and second magnetic components, further reducing the force required from maintenance personnel during the docking operation of the first and second liquid-cooled quick-connect couplings.

[0015] In one implementation, one of the first and second magnetic components is a magnet, and the other is a magnetic part that can be attracted by the magnet. This reduces the cost of the magnetic components.

[0016] In one implementation, the magnet is a permanent magnet. This reduces the cost of the magnetic components.

[0017] In one implementation, the magnet is an electromagnet, which is energized during the docking operation of the first and second liquid-cooled quick-connect couplings and de-energized during the disengagement operation. Thus, during the docking operation, the magnetic force generated by the first and second magnetic components assists the user's operation. During the disengagement operation, no magnetic force is generated between the first and second magnetic components, thus not hindering the separation of the first and second liquid-cooled quick-connect couplings.

[0018] In one implementation, the liquid-cooled distribution unit includes two pairs of first liquid-cooled quick-connect couplings and two pairs of second liquid-cooled quick-connect couplings. The two pairs of first liquid-cooled quick-connect couplings are fixed to the main body of the liquid-cooled distribution unit. The interior of the main body of the liquid-cooled distribution unit includes primary-side piping and secondary-side piping, with one pair of first liquid-cooled quick-connect couplings connecting to both ends of the primary-side piping, and the other pair connecting to both ends of the secondary-side piping. The two pairs of second liquid-cooled quick-connect couplings are fixed to the external frame, with one pair connecting to the primary-side inlet and outlet piping, and the other pair connecting to the secondary-side outlet and inlet piping. Along a first direction, the pair of second liquid-cooled quick-connect couplings is used to connect with the pair of first liquid-cooled quick-connect couplings, and the other pair connecting with the other pair of first liquid-cooled quick-connect couplings.

[0019] Secondly, this disclosure provides a cabinet. The cabinet includes a cabinet body and a liquid-cooled distribution unit as described in any of the first aspects.

[0020] In one implementation, the rack also includes servers. Attached Figure Description

[0042] Figure 1 A schematic diagram of a server rack 100 is shown. (As shown) Figure 1 As shown, the server rack 100 includes a cabinet 110 and a server 120, with the server 120 installed in the cabinet 110. The server 120 provides computing or application services to other client machines (such as smartphones) on the network. The server 120 generates a significant amount of heat during operation; therefore, it is typically equipped with a liquid cooling plate. Correspondingly, as... Figure 1 As shown, the rack 100 also includes a cooling distribution unit (CDU). The cooling distribution unit 130 is used to provide a cooling source for the liquid cooling plates in each server 120.

[0043] In some examples, such as Figure 1 As shown, the liquid cooling distribution unit 130 includes a primary side pipe 11 and a secondary side pipe 12. The two ends of the primary side pipe 11 are connected to a primary side liquid inlet pipe 400 and a primary side liquid outlet pipe 500, respectively. The primary side liquid inlet pipe 400 is connected to the liquid supply channel 200, and the primary side liquid outlet pipe 500 is connected to the liquid return channel 300. The two ends of the secondary side pipe 12 are connected to a secondary side liquid outlet pipe 600 and a secondary side liquid inlet pipe 700, respectively. The secondary side liquid outlet pipe 600 is connected to the liquid inlet of the liquid cooling plate in the server 120, and the secondary side liquid inlet pipe 700 is connected to the liquid outlet of the liquid cooling plate in the server 120.

[0044] During the operation of the liquid cooling distribution unit 130, the low-temperature coolant supplied by the supply channel 200 flows into the primary side pipeline 11 through the primary side inlet pipe 400. The low-temperature coolant in the primary side pipeline 11 exchanges heat with the coolant in the secondary side pipeline 12, and then heats up. The heated coolant flows into the return channel 300 through the primary side outlet pipe 500. The secondary side pipeline 12 supplies low-temperature coolant to the liquid cooling plate through the secondary side outlet pipe 600. After heating up in the liquid cooling plate, the low-temperature coolant flows back to the secondary side pipeline 12 through the secondary side inlet pipe 700. The heated coolant in the secondary side pipeline 12 is cooled down by the coolant in the primary side pipeline 11, and then the secondary side pipeline 12 continues to supply low-temperature coolant to the liquid cooling plate through the secondary side outlet pipe 600. This cycle is repeated continuously, thus achieving liquid cooling heat dissipation for the server 120.

[0045] In practical applications, the two ends of the primary side pipe 11 need to be connected to the primary side inlet pipe 400 and the primary side outlet pipe 500 through a liquid-cooled quick-connect assembly, and the two ends of the secondary side pipe 12 need to be connected to the secondary side outlet pipe 600 and the secondary side inlet pipe 700 through a liquid-cooled quick-connect assembly. This liquid-cooled quick-connect assembly can also be referred to as a fluid connector, etc.

[0046] For example, refer to Figures 2-4 The liquid-cooled distribution unit 130 includes a liquid-cooled distribution unit body 1, an outer frame 2, two pairs of first liquid-cooled quick connectors 3, and two pairs of second liquid-cooled quick connectors 4. The liquid-cooled distribution unit body 1 internally includes a primary side pipe 11 and a secondary side pipe 12. One pair of first liquid-cooled quick connectors 3 connects to both ends of the primary side pipe 11, and the other pair of first liquid-cooled quick connectors 3 connects to both ends of the secondary side pipe 12. The outer frame 2 is slidable relative to the liquid-cooled distribution unit body 1. The two pairs of second liquid-cooled quick connectors 4 are fixed to the outer frame 2. One pair of second liquid-cooled quick connectors 4 connects to the primary side inlet pipe 400 and the primary side outlet pipe 500, respectively, and the other pair of second liquid-cooled quick connectors 4 connects to the secondary side outlet pipe 600 and the secondary side inlet pipe 700, respectively. Maintenance personnel can push the outer frame 2 to allow the two pairs of second liquid cooling quick connectors 4 to connect with the two pairs of first liquid cooling quick connectors 3 respectively, and can pull the outer frame 2 to separate the two pairs of second liquid cooling quick connectors 4 from the two pairs of first liquid cooling quick connectors 3.

[0047] When the first liquid-cooled quick-connect connector 3 and the second liquid-cooled quick-connect connector 4 are connected, they immediately become conductive. When the first liquid-cooled quick-connect connector 3 and the second liquid-cooled quick-connect connector 4 are separated, the first liquid-cooled quick-connect connector 3 can also lock or close the connected pipeline (such as the primary side pipeline 11), and the second liquid-cooled quick-connect connector 4 can also lock or close the connected pipeline (such as the primary side liquid inlet pipeline 400). This allows for quick plugging and unplugging maintenance of modules such as liquid-cooled servers.

[0048] To achieve the aforementioned functions, the structures of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 are relatively complex. In practical applications, maintenance personnel need to exert considerable force to push the outer frame 2 to overcome the mating resistance between the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4, and to allow them to align. This mating resistance includes the friction between the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4, the elastic force of the internal elastic elements of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4, and the liquid pressure provided by the coolant at the moment of connection (before they are fully aligned). This liquid pressure is used to drive the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 to separate. The mating resistance increases rapidly with the increase of the pipe diameter of the liquid-cooled quick connector assembly, making it difficult for a single operator to perform quick plug-and-play maintenance.

[0049] In view of the above-mentioned technical problems, this disclosure provides a liquid-cooled distribution unit 130. Figures 2-4 A schematic diagram of a liquid-cooled distribution unit 130 provided in an embodiment of this disclosure is shown. Figures 2-4 As shown, the liquid-cooled distribution unit 130 includes a liquid-cooled distribution unit body 1, an outer frame 2, a first liquid-cooled quick connector 3, a second liquid-cooled quick connector 4, a first magnetic component 5, and a second magnetic component 6. The first liquid-cooled quick connector 3 is fixed to the liquid-cooled distribution unit body 1, and the second liquid-cooled quick connector 4 is fixed to the outer frame 2. The outer frame 2 and the liquid-cooled distribution unit body 1 are slidably connected along the first direction X (i.e., the outer frame 2 and the liquid-cooled distribution unit body 1 can slide relative to each other along the first direction X). The first liquid-cooled quick connector 3 is used to connect with the second liquid-cooled quick connector 4, and the connection direction is the first direction X. The first magnetic component 5 is fixed to the liquid-cooled distribution unit body 1, and the second magnetic component 6 is fixed to the outer frame 2. The first magnetic component 5 and the second magnetic component 6 are arranged opposite each other in the first direction X, and a magnetic attraction force is generated between them.

[0050] In this embodiment, one of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 is a male connector, and the other is a female connector. For example, the first liquid-cooled quick connector 3 is a female connector, and the second liquid-cooled quick connector 4 is a male connector. In some examples, after the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 are connected, the liquid-cooled distribution unit body 1 and the outer frame 2 are snapped together to ensure stable electrical connection between the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4. The first direction X can be the length direction of the liquid-cooled distribution unit body 1 and the outer frame 2. The first direction X is the insertion / removal direction of the outer frame 2. In addition to the first direction X, this embodiment also defines a second direction Y and a third direction Z, where the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The third direction Z can be understood as the height direction of the cabinet 100.

[0051] The technical solution provided in this disclosure involves setting a first magnetic element 5 and a second magnetic element 6 on the main body 1 of the liquid-cooled distribution unit and the outer frame 2, respectively. This allows the magnetic attraction between the first magnetic element 5 and the second magnetic element 6 to offset some or all of the docking resistance during the docking of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4. This facilitates the docking of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 by maintenance personnel. The docking operation of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 can also be referred to as the insertion or pushing operation of the outer frame 2.

[0052] It should be noted that during the separation of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4, the elastic force of the elastic element and the liquid pressure in the aforementioned docking resistance, since their directions do not change, become separation aids. Therefore, even if magnetic attraction is still generated between the first magnetic element 5 and the second magnetic element 6 during the separation process, the separation operation of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 will not be difficult to complete. The separation operation of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 can also be referred to as the pulling out or removing operation of the outer frame 2.

[0053] This disclosure does not limit the type of the liquid-cooled distribution unit 130; in some examples, such as... Figure 1 As shown, the liquid-cooled distribution unit 130 includes two pairs of first liquid-cooled quick connectors 3 and two pairs of second liquid-cooled quick connectors 4. The two pairs of first liquid-cooled quick connectors 3 are fixed to the main body 1 of the liquid-cooled distribution unit. The main body 1 includes a primary side pipe 11 and a secondary side pipe 12. One pair of first liquid-cooled quick connectors 3 connects to both ends of the primary side pipe 11, and the other pair connects to both ends of the secondary side pipe 12. The two pairs of second liquid-cooled quick connectors 4 are fixed to the outer frame 2. One pair of second liquid-cooled quick connectors 4 connects to the primary side inlet pipe 400 and the primary side outlet pipe 500, respectively, and the other pair connects to the secondary side outlet pipe 600 and the secondary side inlet pipe 700, respectively. Along the first direction X, one pair of second liquid-cooled quick connectors 4 connects to one pair of first liquid-cooled quick connectors 3, and the other pair connects to the other pair of first liquid-cooled quick connectors 3. Of course, the liquid cooling distribution unit 130 can also adopt other structures, such as including more or fewer liquid cooling quick connectors.

[0054] The types of the first magnetic element 5 and the second magnetic element 6 described in this disclosure are not limited. In some examples, both the first magnetic element 5 and the second magnetic element 6 are magnets. In this way, the attraction between the two magnets helps to increase the magnetic attraction between the first magnetic element 5 and the second magnetic element 6.

[0055] In other examples, the first magnetic component 5 is a magnet, and the second magnetic component 6 is a magnetic part that can be attracted by a magnet. Alternatively, the second magnetic component 6 is a magnet, and the first magnetic component 5 is a magnetic part that can be attracted by a magnet. The magnetic part that can be attracted by a magnet can be a component made of magnetic materials such as iron, cobalt, or nickel.

[0056] The magnets mentioned above can be permanent magnets. These permanent magnets may include rare-earth permanent magnet materials, neodymium iron boron, samarium cobalt, ferrite permanent magnet materials, barium ferrite, strontium ferrite, or other permanent magnet alloys.

[0057] The magnets mentioned above can also be electromagnets. Electromagnets generate magnetic attraction when energized and do not generate magnetic attraction when de-energized. Furthermore, the greater the current, the stronger the magnetic attraction. Thus, by controlling the on / off state and magnitude of the current, the magnitude and direction of the magnetic attraction can be more easily controlled.

[0058] For example, the electromagnet is energized during the docking operation of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4. This generates a magnetic attraction between the first magnetic element 5 and the second magnetic element 6, offsetting some of the insertion resistance and facilitating the insertion of the outer frame 2. The electromagnet is also de-energized during the disassembly operation of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4. Thus, when separating the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4, the magnetic attraction is absent, and separation is not hindered. This facilitates the removal of the outer frame 2.

[0059] In some examples, after the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 are mated, the first magnetic element 5 and the second magnetic element 6 come into contact. This helps to increase the magnetic attraction between the first magnetic element 5 and the second magnetic element 6.

[0060] The positions and implementation of the first magnetic element 5 and the second magnetic element 6 will be described below by way of example.

[0061] In some examples, such as Figure 5 As shown, the main body 1 of the liquid-cooled distribution unit includes a second end plate 13. (As indicated...) Figure 6 As shown, the outer frame 2 includes a first end plate 23. (As indicated...) Figure 3 As shown, along the first direction X, the second end plate 13 and the first end plate 23 are arranged opposite to each other. The first liquid-cooled quick connector 3 and the first magnetic element 5 are disposed on the second end plate 13, and the second liquid-cooled quick connector 4 and the second magnetic element 6 are disposed on the first end plate 23. In this way, the magnetic attraction force generated between the first magnetic element 5 and the second magnetic element 6 can drive the first end plate 23 and the second end plate 13 to move closer to each other, thereby facilitating the docking of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4.

[0062] In some examples, such as Figure 6As shown, the outer frame 2 also includes two side plates 21 and a bottom plate 22. The two side plates 21 are arranged opposite each other and are both parallel to the first direction X. The bottom plate 22 is located between the two side plates 21 and is parallel to the first direction X. A first end plate 23 is located at one end of the side plates 21 and the bottom plate 22 and is perpendicular to the first direction X. Figures 2-4 As shown, at least a portion of the liquid-cooled distribution unit body 1 is located in the space enclosed by two side plates 21 and a bottom plate 22. The two side plates 21 are arranged opposite each other along a second direction Y. The side plates 21 are parallel to a first direction X and a third direction Z. The bottom plate 22 is parallel to the first direction X and the second direction Y. The first end plate 23 is parallel to the second direction Y and the third direction Z.

[0063] This disclosure does not limit the implementation of the first magnetic element 5 being disposed on the second end plate 13 and the second magnetic element 6 being disposed on the first end plate 23. Several possible implementations are described below by way of example.

[0064] (1) In some examples, such as Figure 5 As shown, the first magnetic component 5 is fixed to the second end plate 13 of the liquid-cooled distribution unit body 1 and is arranged side by side with the first liquid-cooled quick connector 3. Figure 6 As shown, the second magnetic component 6 is fixed to the first end plate 23 and is arranged side by side with the second liquid-cooled quick connector 4.

[0065] In some examples, such as Figure 7 As shown, the first magnetic element 5 or the second magnetic element 6 includes two fixing ears 51 for screws to pass through, so that the screws fix the magnetic element to the first end plate 23 or the second end plate 13.

[0066] (2) In some examples, such as Figure 8 As shown, the first end plate 23 and the second magnetic component 6 of the outer frame 2 are the same component. The first end plate 23 is made of magnetic material and forms the second magnetic component 6. The first magnetic component 5 is independent of the second end plate 13. Thus, during the docking process of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4, a magnetic attraction force is generated between the first magnetic component 5 and the first end plate 23, which can offset some of the insertion resistance, facilitating the docking operation of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 for maintenance personnel.

[0067] in, Figure 8 The illustrated technical solution can also be described as follows: the liquid-cooled distribution unit 130 includes a liquid-cooled distribution unit body 1, an outer frame 2, a first liquid-cooled quick connector 3, a second liquid-cooled quick connector 4, and a first magnetic component 5. The outer frame 2 includes a first end plate 23, which is made of magnetic material. The first magnetic component 5 is fixed to the liquid-cooled distribution unit body 1 and is disposed opposite to the first end plate 23. A magnetic attraction force is generated between the first magnetic component 5 and the first end plate 23.

[0068] (3) In some examples, such as Figure 9 As shown, the second end plate 13 and the first magnetic component 5 of the liquid-cooled distribution unit body 1 are the same component. The second end plate 13 is made of magnetic material and forms the first magnetic component 5. The second magnetic component 6 is independent of the first end plate 23. Thus, during the docking process of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4, a magnetic attraction force is generated between the second end plate 13 and the second magnetic component 6, which can offset some of the insertion resistance, facilitating the docking operation of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 by maintenance personnel.

[0069] in, Figure 9 The illustrated technical solution can also be described as follows: the liquid-cooled distribution unit 130 includes a liquid-cooled distribution unit body 1, an outer frame 2, a first liquid-cooled quick connector 3, a second liquid-cooled quick connector 4, and a second magnetic component 6. The liquid-cooled distribution unit body 1 includes a second end plate 13, which is made of magnetic material. The second magnetic component 6 is fixed to the outer frame 2 and is disposed opposite to the second end plate 13. A magnetic attraction force is generated between the second end plate 13 and the second magnetic component 6.

[0070] (4) In some examples, such as Figure 10 As shown, the second magnetic component 6 and the first end plate 23 are the same part. The first end plate 23 is made of magnetic material and forms the second magnetic component 6. The first magnetic component 5 and the second end plate 13 of the liquid-cooled distribution unit body 1 are the same part; the second end plate 13 is made of magnetic material and forms the first magnetic component 5. This reduces the need for structural modifications to the liquid-cooled distribution unit 130, requiring only changes to the materials of the first end plate 23 and / or the second end plate 13. Simultaneously, during the docking process of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4, a magnetic attraction force is generated between the second end plate 13 and the first end plate 23, which can offset some of the insertion resistance, facilitating the docking operation of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 for maintenance personnel.

[0071] in, Figure 10 The illustrated technical solution can also be described as follows: the liquid-cooled distribution unit 130 includes a liquid-cooled distribution unit body 1, an outer frame 2, a first liquid-cooled quick connector 3, and a second liquid-cooled quick connector 4. The outer frame 2 includes a first end plate 23, and the liquid-cooled distribution unit body 1 includes a second end plate 13. The first end plate 23 and the second end plate 13 are arranged opposite to each other along a first direction X. The first end plate 23 and the second end plate 13 are made of magnetic material, and a magnetic attraction force is generated between them.

[0072] (5) In some examples, such as Figure 11As shown, the first magnetic component 5 and the first liquid-cooled quick connector 3 are the same part. The first liquid-cooled quick connector 3 is made of magnetic material and forms the first magnetic component 5. The second magnetic component 6 and the second liquid-cooled quick connector 4 are the same part. The second liquid-cooled quick connector 4 is made of magnetic material and forms the second magnetic component 6. Thus, during the mating process of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4, a magnetic attraction force is generated between them, which can offset some of the insertion resistance, facilitating the mating operation of the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 by maintenance personnel.

[0073] in, Figure 11 The illustrated technical solution can also be described as follows: the liquid-cooled distribution unit 130 includes a liquid-cooled distribution unit body 1, an outer frame 2, a first liquid-cooled quick connector 3, and a second liquid-cooled quick connector 4. The first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4 are made of magnetic material, and magnetic attraction is generated between the first liquid-cooled quick connector 3 and the second liquid-cooled quick connector 4.

[0074] In some examples, such as Figure 12 As shown, the first liquid-cooled quick connector 3 includes a tube body 31 and a mounting plate 32. The mounting plate 32 is located around the tube body 31 and is used to fix the first liquid-cooled quick connector 3 to the main body 1 of the liquid-cooled distribution unit. Wherein, as... Figure 11 As shown, since the mounting plate 32 is opposite to the end of the second liquid cooling quick connector 4, the mounting plate 32 can be made of magnetic material and form a first magnetic element 5 to attract the second liquid cooling quick connector 4.

[0075] This disclosure also provides a cabinet 100. For example... Figure 1 As shown, the server rack 100 includes a cabinet 110 and the aforementioned liquid cooling distribution unit 130. Additionally, the server rack 100 may also include a server 120. For details on the specific implementation of the server rack 100, please refer to the foregoing content; further details will not be repeated here.

[0076] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
