Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0061] The present application provides a liquid cooling device 100, such as Figure 1 , 2 As shown, including:

[0062] The box body 1 may include a top plate, a bottom plate and side plates, and a node plug interface 10 is provided on one side of the box body 1;

[0063] A plurality of slots 2 are arranged in the box 1. One or more slots 2 can be formed in the box 1. The slots 2 can be arranged according to actual needs, and there is no limitation on this. One side of the slot 2 corresponds to the node plug interface 10, and the node can be inserted into the slot 2 from one side of the node plug interface 10.

[0064] A liquid cooling input connector 3 is arranged at a side of the slot 2 away from the node plug interface 10, and the liquid cooling input connector 3 is connected to a cooling liquid circulation device through a liquid cooling pipeline, and the cooling liquid circulation device may be, for example, a CDU (Cooling Distribution Units, cooling capacity distribution unit);

[0065] The node 4 is plugged into the slot 2 and locked in the box 1 by the electric self-locking part 40 provided on the node 4. The liquid cooling circulation connector 41 of the node 4 is connected to the liquid cooling input connector 3. The electric self-locking part 40 can be provided at a button of the node 4 located at the node plug interface 10, and the node 4 is locked in the box 1 by pressing the button inside the node 4. It can also be provided on the outside of the box 1, such as a handle provided at the node plug interface 10, and the node 4 is locked by operating the handle from the outside of the box 1. The specific method can be set according to actual needs. A slide 20 is provided on each slot 2, and the slide 20 can provide support for the inserted node 4.

[0066] Wherein, the node 4 also includes a BMC42, and the BMC42 is used to obtain the detection result of the liquid leakage detection in the node 4. If it is determined that the node 4 has a liquid leakage, the electric self-locking part 40 is triggered to unlock, so that the liquid cooling circulation connector 41 is separated from the liquid cooling input connector 3. The liquid leakage detection can be achieved by a liquid leakage detection device, which is electrically connected to the BMC42. After the liquid leakage detection device detects a cold liquid leakage, a liquid leakage signal is generated. If the BMC42 obtains the liquid leakage signal, it can be determined that the cold liquid has leaked in the node 4. If the liquid leakage signal is not detected, it indicates that there is no cold liquid leakage in the node 4. The liquid leakage detection device can be a liquid leakage detection rope, etc., which can be set according to actual needs and is not limited to this.

[0067] The electric self-locking part 40 can have a locked state and an unlocked state. When the node 4 is pushed into the slot 2, the staff can manually operate the electric self-locking part 40 to lock the node 4 in the box 1, or when the node 4 is pushed into the slot 2, the node 4 (such as the BMC) detects that it is pushed into place, and the electric self-locking part 40 is triggered to automatically lock; when the node 4 needs to be taken out, the staff can unlock it by manually operating the electric self-locking part 40 or by sending an unlocking instruction to the node 4 (such as the BMC) to trigger the electric self-locking part 40 to unlock. In other words, the electric self-locking part 40 can at least be unlocked by an electric signal drive, and when the node 4 is locked in the box 1, it can be locked by an electric signal drive, or it can be locked by manual operation of the staff, without restriction.

[0068] In order to realize automatic separation between the liquid cooling input connector 3 and the liquid cooling circulation connector 41, the electric self-locking part 40 needs to be configured to be unlocked by electric signal drive at least. The specific unlocking drive method may be motor drive, electromagnetic drive, etc.

[0069] It should be noted that the liquid cooling device 100 refers to an electronic device with a liquid cooling function, and the electronic device includes but is not limited to a personal computer that can be electrically connected by plugging, a routing device that can be electrically connected by plugging, a switching device, and a server that can be electrically connected by plugging. The node 4 can refer to a motherboard in a personal computer, a board in a routing device or a switching device, and a switching node, a computing node, and a storage node in a server, etc., without limitation.

[0070] The connection between the liquid-cooling input connector 3 and the liquid-cooling circulation connector 41 has a certain plugging force, which enables the liquid-cooling input connector 3 and the liquid-cooling circulation connector 41 to have a separation resilience when they are not locked by the electric self-locking part 40. Depending on the selected liquid-cooling input connector 3 and liquid-cooling circulation connector 41, the magnitude of the plugging force between the two will also be different. Since the node 4 is supported by the slide 20 of the slot 2 during the process of being pushed into the slot 2, there is a certain contact between the node 4 and the slide 20, which generates friction. The relationship between the friction and the above-mentioned resilience will affect the separation method between the liquid-cooling input connector 3 and the liquid-cooling circulation connector 41 controlled by BMC42.

[0071] After the node 4 is plugged into the slot 2 of the liquid cooling device 100, the node 4 is powered on and runs to realize the corresponding functions of the node 4. At this time, the BMC 42 in the node 4 performs liquid leakage detection through the liquid leakage detection device.

[0072] When BMC42 obtains the leakage signal generated by the leakage detection device, BMC42 can drive the electric self-locking part 40 to unlock. When the insertion force between the liquid-cooling input connector 3 and the liquid-cooling circulation connector 41 is greater than the friction force between the slide 20 and the node 4, after the electric self-locking part 40 is unlocked, the liquid-cooling input connector 3 and the liquid-cooling circulation connector 41 pop open and offset the friction force, so that the node 4 moves to the outside of the box 1. Since the liquid-cooling input connector 3 and the liquid-cooling circulation connector 41 are separated, the circulation of the cold liquid in the node 4 is blocked, and the hydraulic pressure in the cold liquid pipeline of the node 4 becomes smaller, which better prevents the continuous leakage of the cold liquid, avoids the cold liquid dripping onto the electronic devices and thus damages the electronic equipment such as the node, and improves the reliability of the electronic equipment with liquid cooling.

[0073] In some cases, when the insertion force between the selected liquid cooling input connector 3 and the liquid cooling circulation connector 41 is smaller than the friction force generated by the support node 4 of the slideway 20, the rebound force generated when the electric self-locking part 40 is unlocked cannot separate the liquid cooling input connector 3 and the liquid cooling circulation connector 41. In this case, other controllable force structures are required in the liquid cooling device 100 to assist in pushing the liquid cooling input connector 3 and the liquid cooling circulation connector 41 apart.

[0074] Optionally, the liquid cooling device 100, such as Figure 3 , 4As shown, it also includes RMC (Rack Management Controller) 5 and unlocking unit 6. In a liquid cooling device 100, an RMC 5 can be provided to control the push-out of all or part of the nodes 5 therein. The RMC 5 can interact with the BMC 42 in each node 4 for data. For example, the node 4 and the RMC 5 are respectively plugged into the backplane 8 of the liquid cooling device 100. The location in the liquid cooling device 100 can be set according to actual needs without limitation. The unlocking unit 6 is used to apply additional force to the node 4 to offset the friction between the slide 20 and the node 4, forcing the box 1 of the node 4 to be pushed out;

[0075] The BMC 42 is further configured to send a leakage notification to the RMC 5 if it is determined that leakage occurs in the node 4, wherein the leakage notification carries the slot number of the node 4;

[0076] The RMC5 is used to drive the unlocking part 6 at the position corresponding to the slot number to separate the liquid cooling circulation connector 41 and the liquid cooling input connector 3 if receiving the liquid leakage notification sent by the BMC42.

[0077] When node 4 is inserted into slot 2, BMC 42 can determine which slot 2 node 4 is connected to, for example, Figure 3 In the example, node 4 is inserted into slot 2A, and determines the slot number of slot 2A where the node is located by interacting with management node 7 or reading the value in the register set on backplane 8. The specific method of obtaining the slot number can be set according to actual needs. BMC 42 stores the obtained slot number.

[0078] When BMC42 detects leakage in node 4, BMC42 needs to perform two operations: unlocking electric self-locking unit 40 and driving unlocking unit 6. Since unlocking electric self-locking unit 40 belongs to node 4, it can be directly driven by BMC42, while unlocking unit 6 needs to be controlled by RMC5. Therefore, BMC42 needs to notify RMC5 which node 4 has leakage, that is, BMC42 sends leakage notification to RMC5.

[0079] The corresponding relationship between the slot number and the unlocking part 6 may be recorded in the RMC 5. The unlocking part 6 is turned on by an electric switch. Then the corresponding relationship may be formed by the slot number and the switch identification of the unlocking part 6.

[0080] After receiving the leakage notification, RMC5 obtains the slot number carried therein and determines the slot where the node 4 with the leakage problem is located. After obtaining the slot number, RMC5 can find the unlocking part 6 corresponding to the slot according to the slot number recorded by itself and drive it to assist in pushing out the corresponding node 4.

[0081] Optionally, the unlocking portion 6, such as Figure 4 , 5 As shown, including:

[0082] The push rod 6A is arranged on the side of the slot 2 away from the node plug-in interface 10 or on the box 1 on both sides of the slot 2 and the node plug-in interface 10, and is driven by the RMC5 to move in the opposite direction of the node 2 insertion direction;

[0083] The RMC5 is specifically used to drive the push rod 6A at the position corresponding to the slot number to push the node 4 inserted into the slot 2 to separate the liquid cooling circulation connector 41 and the liquid cooling input connector 3 if receiving the liquid leakage notification sent by the BMC42.

[0084] The force applied by the push rod 6A to push out the node 4 can be achieved by a spring. When the staff pushes in the node 4, the spring against the push rod 6A is compressed and can be locked. When the RMC5 receives a liquid leakage notification, the push rod 6A can be controlled to unlock. When the electric self-locking part 40 is also unlocked, the node 4 can be assisted to be pushed out under the action of the spring rebound force, thereby separating the liquid cooling circulation connector 41 and the liquid cooling input connector 3.

[0085] In another case, the push rod 6A can be driven by a motor or the like to apply force to the node 4 so that the node 4 is partially pushed out of the housing 1 , thereby achieving separation of the liquid cooling circulation connector 41 and the liquid cooling input connector 3 .

[0086] exist Figure 4 In the embodiment, the push rod 6A is arranged in the slot 2 and away from the node plug interface 10. After the node 4 is inserted into the slot 2, the push rod 6A abuts against the rear side plate 43 of the shell of the node 4. When the push rod 6A is driven by the RMC5, the node 4 is pushed from the rear side to move outside the box 1.

[0087] exist Figure 5 In the embodiment, the push rod 6A is arranged at a position close to the node plug interface 10 of the slot 2, and a folded edge 44 may be arranged on the front side of the shell of the node 4. When the node 4 is inserted into the slot 2, the folded edge 44 abuts against the push rod 6A. When the push rod 6A is driven by the RMC 5, the node 4 is pushed from the front side to move outside the box 1.

[0088] In order to achieve balanced pushing on both sides of node 4, push rod 6A can be respectively set on both sides of box 1. When push rod 6A is driven, both sides of node 4 are pushed evenly, thereby avoiding the problem of node 4 offset and hitting box 1 during the process of node 4, further improving the reliability of liquid cooling equipment.

[0089] Optionally, the unlocking portion 6, such as Figure 4 , 6 As shown, including:

[0090] The rotating wheel 6B is arranged on the slideway 20 of the slot 2 and abuts against the node 4 in the slot 2. The rotating wheel 6B can be driven by a motor to rotate;

[0091] The RMC5 is specifically used to drive the rotating wheel 6B at the position corresponding to the slot number to move the node 4 inserted into the slot 2 to the outside of the box 1 to separate the liquid cooling circulation connector 41 and the liquid cooling input connector 3 if a liquid leakage notification is received from the BMC42.

[0092] When the node 4 is pushed into the slot 2 , the rotating wheel 6B contacts the node 4 . Since the rotating wheel 6B will not be locked when not controlled, the rotating wheel 6B can rotate as the node 4 is pushed in, and will not limit the pushing in of the node 4 .

[0093] When BMC 42 detects that node 4 is leaking, it unlocks electric self-locking unit 40 and sends a leak notification to RMC 5. When RMC 5 receives the leak notification, it controls the rotation wheel 6B to rotate through the motor, and the rotation causes node 4 to move outside of the box 1, thereby separating the liquid cooling circulation connector 41 and the liquid cooling input connector 3.

[0094] In order to achieve balanced pushing of both sides of node 4, the rotating wheels 6B can be respectively arranged on the slides 20 on both sides of the box 1. When the rotating wheels 6B are driven, both sides of node 4 are pushed evenly, thereby avoiding the problem of node 4 offset and hitting the box 1 during the process of node 4, further improving the reliability of the liquid cooling equipment.

[0095] Correspondingly, the present application also provides a method for handling liquid leakage, such as Figure 7 As shown, it is applied to Figure 1 The liquid cooling device shown, wherein the liquid cooling device 100 comprises: a box body 1; a plurality of slots 2, arranged in the box body 1; a liquid cooling input connector 3, arranged on a side of the slot 2, away from the node plug interface 10; a node 4, plugged into the slot 2, and locked in the box body by an electric self-locking part 40 arranged on the node 4, and a liquid cooling circulation connector 41 of the node 4 is connected to the liquid cooling input connector 3;

[0096] The method comprises:

[0097] S700. The BMC obtains a detection result of a liquid leakage detection of the node where the BMC is located.

[0098] The BMC is arranged on the node, and the node is inserted into a slot.

[0099] S701: If it is determined that liquid leakage occurs in the node, the BMC triggers the electric self-locking unit to unlock, so that the liquid cooling circulation connector is separated from the liquid cooling input connector.

[0100] After the node 4 is plugged into the slot 2 of the liquid cooling device 100, the node 4 is powered on and runs to realize the corresponding functions of the node 4. At this time, the BMC 42 in the node 4 performs liquid leakage detection through the liquid leakage detection device.

[0101] When BMC42 obtains the leakage signal generated by the leakage detection device, BMC42 can drive the electric self-locking part 40 to unlock. When the insertion force between the liquid-cooling input connector 3 and the liquid-cooling circulation connector 41 is greater than the friction force between the slide 20 and the node 4, after the electric self-locking part 40 is unlocked, the liquid-cooling input connector 3 and the liquid-cooling circulation connector 41 pop open and offset the friction force, so that the node 4 moves to the outside of the box 1. Since the liquid-cooling input connector 3 and the liquid-cooling circulation connector 41 are separated, the circulation of the cold liquid in the node 4 is blocked, and the hydraulic pressure in the cold liquid pipeline of the node 4 becomes smaller, which better prevents the continuous leakage of the cold liquid, avoids the cold liquid dripping onto the electronic devices and thus damages the electronic equipment such as the node, and improves the reliability of the electronic equipment with liquid cooling.

[0102] When the plugging force is greater than the friction force, the liquid-cooling input connector 3 and the liquid-cooling circulation connector 41 can be separated by the rebound force corresponding to the plugging force generated by unlocking the electric self-locking part 40 .

[0103] In the case where the insertion force is smaller than the friction force, the liquid cooling input connector 3 and the liquid cooling circulation connector 41 can be separated by providing the RMC 5 and the unlocking portion 6 in the liquid cooling device 100 .

[0104] Optionally, the liquid cooling device 100 further includes an RMC 5 and an unlocking unit 6;

[0105] After the BMC obtains the detection result of the liquid leakage detection of the node where the BMC is located in step S700, the following further includes:

[0106] S702: If it is determined that leakage occurs in the node, the BMC sends a leakage notification to the RMC, wherein the leakage notification carries the slot number where the node is located.

[0107] S703: If the liquid leakage notification sent by the BMC is received, the RMC drives the unlocking part at the position corresponding to the slot number to separate the liquid cooling circulation connector and the liquid cooling input connector.

[0108] When node 4 is inserted into slot 2, BMC 42 can determine which slot 2 node 4 is connected to, for example, Figure 3In the example, node 4 is inserted into slot 2A, and determines the slot number of slot 2A where the node is located by interacting with management node 7 or reading the value in the register set on backplane 8. The specific method of obtaining the slot number can be set according to actual needs. BMC 42 stores the obtained slot number.

[0109] When BMC42 detects leakage in node 4, BMC42 needs to perform two operations: unlocking electric self-locking unit 40 and driving unlocking unit 6. Since unlocking electric self-locking unit 40 belongs to node 4, it can be directly driven by BMC42, while unlocking unit 6 needs to be controlled by RMC5. Therefore, BMC42 needs to notify RMC5 which node 4 has leakage, that is, BMC42 sends leakage notification to RMC5.

[0110] The corresponding relationship between the slot number and the unlocking part 6 may be recorded in the RMC 5. The unlocking part 6 is turned on by an electric switch. Then the corresponding relationship may be formed by the slot number and the switch identification of the unlocking part 6.

[0111] After receiving the leakage notification, RMC5 obtains the slot number carried therein and determines the slot where the node 4 with the leakage problem is located. After obtaining the slot number, RMC5 can find the unlocking part 6 corresponding to the slot according to the slot number recorded by itself and drive it to assist in pushing out the corresponding node 4.

[0112] Optionally, the unlocking portion 6 comprises:

[0113] The push rod 6A, which is arranged on the side of the slot 2 away from the node plug-in interface 10 or on the box 1 on both sides of the node plug-in interface 10 of the slot 2, is driven by the RMC5 to move in the opposite direction of the node insertion direction.

[0114] In step S702, if the liquid leakage notification sent by the BMC is received, the RMC drives the unlocking part at the position corresponding to the slot number to separate from the liquid cooling circulation connector and the liquid cooling input connector, specifically:

[0115] If the liquid leakage notification sent by the BMC is received, the RMC drives the push rod at the position corresponding to the slot number to push the node inserted into the slot to separate the liquid cooling circulation connector and the liquid cooling input connector.

[0116] The force applied by the push rod 6A to push out the node 4 can be achieved by a spring. When the staff pushes in the node 4, the spring against the push rod 6A is compressed and can be locked. When the RMC5 receives a liquid leakage notification, the push rod 6A can be controlled to unlock. When the electric self-locking part 40 is also unlocked, the node 4 can be assisted to be pushed out under the action of the spring rebound force, thereby separating the liquid cooling circulation connector 41 and the liquid cooling input connector 3.

[0117] In another case, the push rod 6A can be driven by a motor or the like to apply force to the node 4 so that the node 4 is partially pushed out of the housing 1 , thereby achieving separation of the liquid cooling circulation connector 41 and the liquid cooling input connector 3 .

[0118] Optionally, the unlocking portion 6 comprises:

[0119] The rotating wheel 6B is arranged on the slideway 20 of the slot 2 and abuts against the node 4 in the slot 2;

[0120] In step S702, if the liquid leakage notification sent by the BMC is received, the RMC drives the unlocking part at the position corresponding to the slot number to separate from the liquid cooling circulation connector and the liquid cooling input connector, specifically:

[0121] If the liquid leakage notification sent by the BMC is received, the RMC drives the rotating wheel at the position corresponding to the slot number to drive the node inserted into the slot to move outside the box to separate the liquid cooling circulation connector and the liquid cooling input connector.

[0122] When the node 4 is pushed into the slot 2 , the rotating wheel 6B contacts the node 4 . Since the rotating wheel 6B will not be locked when not controlled, the rotating wheel 6B can rotate as the node 4 is pushed in, and will not limit the pushing in of the node 4 .

[0123] When BMC 42 detects that node 4 is leaking, it unlocks electric self-locking unit 40 and sends a leak notification to RMC 5. When RMC 5 receives the leak notification, it controls the rotation wheel 6B to rotate through the motor, and the rotation causes node 4 to move outside of the box 1, thereby separating the liquid cooling circulation connector 41 and the liquid cooling input connector 3.

[0124] In order to achieve balanced pushing of both sides of node 4, the rotating wheels 6B can be respectively arranged on the slides 20 on both sides of the box 1. When the rotating wheels 6B are driven, both sides of node 4 are pushed evenly, thereby avoiding the problem of node 4 offset and hitting the box 1 during the process of node 4, further improving the reliability of the liquid cooling equipment.

[0125] Correspondingly, the present application also provides a leakage treatment device, such as Figure 8 As shown, a BMC for a node in a liquid cooling device, wherein the liquid cooling device 100 comprises: a box 1; a plurality of slots 2, which are arranged in the box 1; a liquid cooling input connector 3, which is arranged on a side of the slot 2 away from the node plug interface 10; a node 4, which is plugged into the slot 2 and locked in the box by an electric self-locking part 40 arranged on the node 4, and a liquid cooling circulation connector 41 of the node 4 is connected to the liquid cooling input connector 3;

[0126] The liquid leakage processing device comprises:

[0127] A detection unit, used to obtain the detection result of the leakage detection of the node where the detection unit is located;

[0128] The separation unit is used for, if it is determined that liquid leakage occurs in the node, the BMC triggers the electric self-locking part to unlock, so as to separate the liquid cooling circulation connector from the liquid cooling input connector.

[0129] In some cases, the liquid leakage processing device can be divided into two parts, namely, a first liquid leakage processing device executed in BMC42 and a second liquid leakage processing device executed in RMC5, wherein the detection unit and the separation unit are arranged in the first liquid leakage processing device.

[0130] Optionally, the liquid cooling device 100 further includes an RMC 5 and an unlocking unit 6;

[0131] The separation unit is also used to send a leakage notification carrying the slot number of the node to the RMC if it is determined that leakage occurs in the node, so that after the RMC receives the leakage notification, it drives the unlocking part at the position corresponding to the slot number to separate the liquid cooling circulation connector and the liquid cooling input connector.

[0132] The second liquid leakage processing device comprises:

[0133] The driving unit is configured to drive the unlocking part at the position corresponding to the slot number to separate from the liquid cooling circulation connector and the liquid cooling input connector if a liquid leakage notification sent by the BMC is received.

[0134] Optionally, the unlocking portion 6 comprises:

[0135] The push rod 6A is arranged on the side of the slot 2 away from the node plug-in interface 10 or on the box 1 on both sides of the slot 2 and the node plug-in interface 10, and is driven by the RMC5 to move in the opposite direction of the node 2 insertion direction;

[0136] The driving unit in the second liquid leakage processing device is further used to drive the push rod at the position corresponding to the slot number to push the node inserted into the slot if a liquid leakage notification sent by the BMC is received, so as to separate the liquid cooling circulation connector and the liquid cooling input connector.

[0137] Alternatively, the unlocking portion 6 comprises:

[0138] The rotating wheel 6B is arranged on the slideway 20 of the slot 2 and abuts against a node in the slot 2;

[0139] The driving unit in the second liquid leakage processing device is specifically used to drive the rotating wheel at the position corresponding to the slot number to drive the node inserted into the slot to move outside the box body to separate the liquid cooling circulation connector and the liquid cooling input connector if a liquid leakage notification sent by the BMC is received.
