Description

Technical Field

[0001] This application relates to the field of computer room cooling technology, and more particularly to a computer room system. Background Technology

[0002] The data center is equipped with multiple rack groups, each of which includes multiple racks arranged side by side. Adjacent rack groups are arranged in parallel, and the space between adjacent rack groups forms a cold aisle.

[0003] The cold aisle is managed in a fully enclosed manner. The sides of the cold aisle, corresponding to the racks at both ends of adjacent rack groups (e.g., row-end racks or start-up boxes), are equipped with enclosed doors for easy personnel access. The ceiling of the cold aisle has multiple openable skylights, and the plane of each skylight is parallel to the ceiling of the cold aisle when closed. The closed doors and skylights create a sealed environment for the corresponding cold aisle.

[0004] The skylight uses a magnetic attraction mechanism. When the cold aisle temperature reaches the set value, a fire emergency shut-off occurs, or the emergency window opening button is pressed, the electromagnet on the skylight is de-energized, causing the skylight to detach and rotate naturally along the corresponding axis under gravity until it comes to a stop. The skylight then rotates in reverse until it is perpendicular to the top of the cold aisle. Before restoring the cold aisle to its closed state, the fire emergency shut-off is released, and the power to the cold aisle controller is restored.

[0005] However, cold aisle controllers are typically powered by a single uninterruptible power supply (UPS) or dual mains power supplies. A power failure in the cold aisle controller or a malfunction in the skylight's magnetic closure can cause the skylight to detach, preventing the cold aisle from remaining closed and resulting in abnormal cold aisle control.

[0006] How to detect sunroof detachment in a timely manner and ensure the normal operation of the cold aisle is a technical problem that needs to be solved. Utility Model Content

[0007] The purpose of this application embodiment is to provide a computer room system to address the problem of abnormal cold aisle control caused by skylight detachment.

[0008] To solve the above-mentioned technical problems, this specification is implemented as follows:

[0009] Firstly, a data center system is provided, including:

[0010] Multiple rack groups, with two adjacent rack groups arranged in parallel, and the space between two adjacent rack groups forming a cold aisle. Each rack group includes multiple racks arranged side by side.

[0011] Multiple skylights are installed at the top of the cold aisle and connected to the two cabinet groups corresponding to the cold aisle. When the skylight is closed, the plane of each skylight is parallel to the top of the cold aisle; when it is detached, it rotates along the axis to be perpendicular to the top of the cold aisle.

[0012] Enclosed doors are installed at both ends of the cold aisle. When closed, the doors and skylights keep the corresponding cold aisles closed.

[0013] Photoelectric switches are installed on the cabinets at both ends of each cabinet group. They are used to trigger the output of the first switch signal when the target skylight rotates along the axis in the detached state.

[0014] The acquisition module is connected to the photoelectric switch and is used to acquire the first switch signal and send an alarm signal based on the acquired first switch signal.

[0015] Optionally, the photoelectric switch is a through-beam photoelectric switch, which includes a transmitter for emitting light and a receiver for receiving light. The transmitter is disposed on the cabinet at one end of the cabinets at both ends, and the receiver is disposed on the cabinet at the other end of the cabinets at both ends.

[0016] Optionally, the photoelectric switch is a reflective photoelectric switch, and the reflective photoelectric switch is installed on the cabinet at either end of the cabinets at both ends.

[0017] Optionally, the cabinets at both ends include a fixed plate parallel to the top of the cold aisle. The photoelectric switch is located on the inner side of the fixed plate facing the cold aisle and is triggered to output the first switch signal when the target skylight is rotated to the target position along the axis.

[0018] Optionally, it also includes:

[0019] Limit switches are installed on the cabinets at both ends or on the door frame of the closed door, and contact the closed door when the closed door is opened, so as to output a second switch signal after the closed door has been open for a preset time.

[0020] The acquisition module is also connected to the limit switch and is used to acquire the second switch signal and send an alarm signal based on the acquired second switch signal.

[0021] Optionally, the closed door is a sliding closed door, and the limit switch is installed on the door frame of the closed door adjacent to one of the movable doors of the sliding closed door; or

[0022] The closed door is a double-leaf closed door, and the limit switches are respectively installed on the slide rails of the closed door adjacent to the two movable leaves of the double-leaf closed door.

[0023] Optionally, the cabinets at both ends include a fixed plate parallel to the top of the cold aisle, and the limit switch is disposed on the inner side of the fixed plate facing the cold aisle and in an area adjacent to the movable target door in the closed door.

[0024] Optionally, it also includes:

[0025] A movable push rod is set on one side of the top of each cold aisle, parallel to the direction in which multiple cabinets of the cabinet group are arranged side by side. One end of the movable push rod is connected to the first end of a steel wire rope.

[0026] The wire rope has a second end connected to a wire rope tensioning wheel, which can rotate in a first direction to tighten the wire rope.

[0027] A flexible pull rope, the first end of which is fixed to each skylight, and the second end of which is fixed to the movable push rod;

[0028] When the wire rope tensioning wheel rotates along the first direction, the movable push rod drives the flexible pull rope to move along the direction in which the plurality of cabinets are arranged side by side, so that each skylight perpendicular to the top of the cold aisle rotates along the axis to be parallel to the top of the cold aisle.

[0029] Optionally, each skylight includes a first sub-skylight and a second sub-skylight that are symmetrical about the axis, and the first sub-skylight of one of two adjacent skylights is provided with a fixed pulley on the skylight side that is parallel to and away from the axis.

[0030] The first end of the flexible pull rope is fixed to the second sub-skylight of another skylight among two adjacent skylights, and the second end of the flexible pull rope passes through the fixed pulley and is fixed to the movable push rod.

[0031] Optionally, a spring is provided at the other end of the movable push rod, and the spring pushes the movable push rod to reset after the wire rope tensioning wheel is released.

[0032] In this embodiment, by setting photoelectric switches and corresponding acquisition modules on the cabinets at both ends of two adjacent cabinet groups, an alarm can be generated in a timely manner when any skylight falls off, reminding maintenance personnel to discover and quickly handle related problems. It has the advantages of simple structure, convenient operation and cost-saving manufacturing. Attached Figure Description

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. The drawing numbers in this application are only used to distinguish the various steps in the solution and are not used to limit the execution order of the various steps. The specific execution order is subject to the description in the specification.

[0038] To address the problems existing in the prior art, this application provides a data center system, combined with... Figures 1 to 3 The data center system includes: multiple rack groups 200, with adjacent rack groups 200 arranged in parallel, and the space between adjacent rack groups 200 forming a cold aisle. Each rack group 200 includes multiple racks 222 and 220 arranged side by side; multiple skylights 3, 7, and 9, located at the top of the cold aisle and connected to the two rack groups 200 corresponding to their respective cold aisles. The plane of each skylight is parallel to the top of the cold aisle when closed, and rotates along axis 8 to be perpendicular to the top of the cold aisle when detached; sealing doors 100, respectively located at both ends of the cold aisle, with the sealing doors 100 and each skylight in the closed state making the corresponding cold aisle closed; photoelectric switches 20, located on the racks 222 at both ends of each rack group 200, used to trigger and output a first switch signal when the target skylight rotates along axis 8 in the detached state; and a data acquisition module 40, connected to the photoelectric switches 20, used to acquire the first switch signal and send an alarm signal based on the acquired first switch signal.

[0039] Figure 1 This is a perspective view of the computer room system according to an embodiment of this application. Figure 2 It is along Figure 1 A cross-sectional view of the sunroof in the AA direction.

[0040] like Figure 1 and Figure 2As shown, the target data center is equipped with multiple rack groups 200. Each rack group 200 includes multiple racks arranged side by side, including racks 222 located at both ends of the rack group 200 and rack 220 in the middle. Adjacent rack groups 200 are arranged in parallel, and the space between adjacent rack groups 200 forms a cold aisle.

[0041] The cold aisle is managed in a fully enclosed manner. At both ends of the cold aisle, corresponding to the cabinets 222 at the ends of two adjacent cabinet groups 200, enclosed doors 100 are installed for easy personnel access. The top of the cold aisle is equipped with multiple openable skylights 3, 7, and 9. For example, when skylight 9 is closed, its plane is parallel to the top of the cold aisle. When skylights 3 and 7 are detached, they rotate along axis 8 to a state that is essentially perpendicular to the top of the cold aisle.

[0042] The closed doors and skylights in the closed state enclose the corresponding cold aisles, allowing for cooling of the corresponding cabinet group 200. Photoelectric switches 20 are installed on cabinets 222 adjacent to the closed doors 100 at both ends of the cold aisle. These switches are triggered to output a first switch signal when any skylight detaches and rotates along the axis. This first switch signal indicates that the skylight is in the detached and open state. When the skylight rotates along the axis in the detached state, it blocks the laser path of the photoelectric switch 20, causing the switch to activate and output the first switch signal.

[0043] The acquisition module 40, connected to the photoelectric switch 20, acquires the first switch signal and sends an alarm signal to prompt relevant personnel to promptly detect the detachment of the skylight and take appropriate measures to reclose the skylight and restore the cold aisle to normal operation.

[0044] The cause of the skylight detachment may be a power failure in the cold aisle controller or a magnetic malfunction in the skylight. Relevant personnel can detect and repair the corresponding faults to restore the normal operation of the cold aisle in a timely manner, avoid the high temperature risk of the server racks, and ensure that the server racks operate in a stable and safe environment.

[0045] In one embodiment, the photoelectric switch 20 is a through-beam photoelectric switch, which includes a transmitter for emitting light and a receiver for receiving light. The transmitter is disposed on the cabinet at one end of the cabinets at both ends, and the receiver is disposed on the cabinet at the other end of the cabinets at both ends.

[0046] Combination Figure 2An example of a through-beam photoelectric switch is given. In this example, the through-beam photoelectric switch includes a transmitter 22 for emitting light and a receiver 24 for receiving light. The transmitter 22 is disposed on a cabinet 222 at one end of the cabinets at both ends of the cabinet group 200, and the receiver 24 is disposed on a cabinet 222 at the other end of the cabinets at both ends of the cabinet group 200.

[0047] When there is no obstruction, the light emitted by the transmitter 22 of the through-beam photoelectric switch travels in a straight line and is received by the receiver 24 of the through-beam photoelectric switch. If the receiver 24 does not receive the light emitted by the transmitter 22, the through-beam photoelectric switch will activate and send a first switching signal.

[0048] Therefore, to accurately detect skylight detachment, in this embodiment, a through-beam photoelectric switch is installed on the cabinets 222 at both ends of the cabinet assembly 200. This switch can be triggered during rotation along the axis after any skylight detaches, for example, when the light emitted by the transmitter 22 travels along a straight path and passes a certain position during the rotation of the skylight along the axis after detachment. Therefore, when the skylight rotates to the corresponding position after detachment, the light emitted by the transmitter 22 is blocked by the non-transparent part of the skylight, causing the receiver 24 to be unable to receive the corresponding light, thus triggering the through-beam photoelectric switch to issue a first switching signal. The through-beam photoelectric switch is suitable for long-distance skylight detachment detection, with an effective distance of over 30 meters.

[0049] In another embodiment, the photoelectric switch 20 is a reflective photoelectric switch, which is disposed on the cabinet at either end of the cabinets at both ends.

[0050] A reflective photoelectric switch includes a transmitter and a receiver housed in one component. The transmitter emits light, and if there is an obstruction in the straight-line propagation path of the light, the receiver can receive the light reflected back from the obstructing object. If the obstructing object is a detached skylight, the reflected light indicates that the skylight is currently detached.

[0051] Therefore, to accurately detect skylight detachment, in this embodiment, a reflective photoelectric switch is installed on one of the cabinets 222 at both ends of the cabinet assembly 200. This switch can be triggered during the rotation along the axis after any skylight detaches. For example, the light emitted by the emitter of the reflective photoelectric switch travels along a straight path and passes a certain position during the rotation of the skylight along the axis after detachment. Therefore, when the skylight rotates to the corresponding position after detachment, the light emitted by the emitter is blocked by the non-transparent part of the skylight and reflected back. The corresponding light is received by the receiver of the reflective photoelectric switch, triggering the reflective photoelectric switch to issue a first switching signal. The reflective photoelectric switch is suitable for close-range skylight detachment detection.

[0052] Specifically, in combination Figure 1 The cabinets 222 at both ends include a fixed plate 2224 parallel to the top of the cold aisle. The photoelectric switch 20 is located on the inner side of the fixed plate 2224 facing the cold aisle, and is triggered to output the first switch signal when the target skylight is rotated to the target position along the axis.

[0053] On the two cabinets 222 on either side of the cold aisle, with their top mounting plates facing inwards, are installed transmitters 22 and receivers 24 of through-beam photoelectric switches, respectively. Alternatively, on the top mounting plate of one cabinet 222 on either side of the cold aisle, facing inwards, is installed a reflective photoelectric switch. Installing either through-beam or reflective photoelectric switches does not affect the opening of the enclosure door 100 or normal operation of the cabinet 222. If a skylight detaches and its non-transparent portion blocks light, the photoelectric switch will activate, triggering a first switch signal. This first switch signal is collected by the acquisition module 40 and transmitted to the environmental monitoring system via the corresponding branch channel of the cabinet 222 (the starting cabinet), triggering an environmental monitoring alarm.

[0054] In one example, the alarm can be triggered using the spare branch channel of cabinet 222 corresponding to the column head cabinet (starting box). Therefore, no major modifications are needed when an alarm occurs, and the alarm message can be modified to: "XX cold aisle skylight detachment". If you do not want a skylight detachment alarm to be generated, simply turn off the power to photoelectric switch 20. For example, one end of DC24V power switch 60 is connected to photoelectric switch 20, and the other end of DC24V power switch 60 is connected to cold aisle controller power switch 50. The cold aisle controller is powered by a UPS or dual AC power supply. By controlling DC24V power switch 60, you can power on or power off photoelectric switch 20. By controlling cold aisle controller power switch 50, you can power on or power off DC24V power switch 60.

[0055] Combination Figure 3 Photoelectric switch 20 is an NPN photoelectric switch. Brown represents the positive terminal of the NPN photoelectric switch, blue represents the negative terminal of the NPN photoelectric switch, and black represents the output of the NPN photoelectric switch. When there is a voltage difference between the positive terminal and the output, the current relay (KA) 26 closes, triggering the KA-type contact 28 to close. The NPN photoelectric switch generates the first switching signal of voltage, which is sent to the acquisition module 40 via the current relay 26, the DC24V power switch 60, and the contact 28. If the acquisition module 40 detects the voltage, it will issue an alarm signal for the backup branch.

[0056] In one embodiment, the photoelectric switch 20 is a PNP photoelectric switch, which operates on a similar principle to the NPN photoelectric switch, and will not be described in detail here.

[0057] In one embodiment, the data center system further includes: a limit switch, disposed on the racks at both ends or on the door frame of the closed door, and contacting the closed door when the closed door is opened, so as to output a second switch signal after the closed door has been open for a preset time; and a data acquisition module, which is also connected to the limit switch and is also used to acquire the second switch signal and send an alarm signal based on the acquired second switch signal.

[0058] The above embodiments can also realize an alarm for the closed door 100 not being closed. Specifically, a limit switch is installed on the cabinet 222 of the closed door 100 adjacent to the cold aisle. As long as the closed door 100 is closed in place, the limit switch will be activated, and it is determined that the closed door 100 of the cold aisle is closed normally.

[0059] Combination Figure 3 When the cold aisle enclosure door 100 is normally closed, it presses against the limit switch, causing the normally closed contact of the limit switch to open and the time relay 36 to be de-energized. When the cold aisle enclosure door 100 is opened, the normally closed contact of the limit switch closes, and the time relay (KT) 36 is energized. To avoid unnecessary alarms caused by normal access to the cold aisle, the enclosure door 100 is opened with a delayed alarm. That is, after a preset time after the enclosure door 100 is open, the KT contact 38 is triggered to close, and the limit switch generates a second switching signal with voltage. This signal is then sent to the acquisition module 40 via the time relay 36 and contact 38. If the acquisition module 40 detects the voltage, it issues an alarm signal for the backup branch.

[0060] Optionally, the closed door 100 is a sliding closed door, and the limit switch is disposed on the door frame of the closed door adjacent to one of the movable doors of the sliding closed door; or the closed door 100 is a double closed door, and the limit switches are respectively disposed on the slide rails of the closed door adjacent to the two movable doors of the double closed door.

[0061] If a sliding closed door has only one movable door, a limit switch is installed on the door frame adjacent to that movable door to detect if the closed door is in a normally closed state or has not closed after being opened for a preset time. If a double-leaf closed door has two movable doors, two limit switches are installed on the tracks of the two movable doors, which are the components that pull the doors open and close. If there are closed doors at both ends of the cold aisle, limit switches are installed on the corresponding door frames or tracks of the closed doors at both ends.

[0062] Figure 3An example of a double-leaf type closed door is given. Limit switches 42 and 44 are respectively installed on the door frames adjacent to the two movable doors of the double-leaf type closed door. When any door of the cold aisle closed door 100 is opened, the normally closed contact of the corresponding limit switch closes, the time relay 36 is energized, and after a preset time after any door of the closed door 100 has been opened, the trigger contact 38 closes, and the corresponding limit switch generates a second switching signal. The second switching signal is collected by the acquisition module 40 and transmitted to the environmental monitoring system through the corresponding branch channel of the cabinet 222 of the column head cabinet (starting box), triggering the environmental monitoring alarm.

[0063] In one example, the alarm can be triggered using the spare branch channel of the cabinet 222 corresponding to the column head cabinet (starting box). Therefore, no major modifications are needed when the alarm is triggered, and the alarm message is modified to: "XX cold aisle closed door has been opened".

[0064] Optionally, the cabinets at both ends include a fixed plate parallel to the top of the cold aisle, and the limit switch is disposed on the inner side of the fixed plate facing the cold aisle and in an area adjacent to the movable target door in the closed door.

[0065] On the two racks 222 on either side of the cold aisle, with their top mounting plates facing inwards towards the cold aisle, corresponding limit switches are installed above the inner side of the door frame of the cold aisle enclosure door 100. Whether it's a sliding or double-leaf enclosure door, as long as the enclosure door is fully closed, the limit switch will activate, indicating normal closure. After a delay, an alarm is triggered when the enclosure door opens, and the alarm is transmitted remotely to the environmental monitoring system via the backup branch of rack 222.

[0066] This application embodiment further utilizes limit switches to detect cold aisle closure anomalies caused by cold aisle doors not being closed in a timely manner. Once an anomaly is detected, an alarm is immediately generated to remind maintenance personnel to respond quickly and close the corresponding cold aisle door in a timely manner.

[0067] In one embodiment, combined Figure 1 and Figure 2The data center system also includes: a movable push rod 1, parallel to the direction in which multiple server racks of the rack group 200 are arranged side by side, and located on one side of the top of each cold aisle; one end of the movable push rod 1 is connected to the first end of a steel wire rope 11; the second end of the steel wire rope 11 is connected to a steel wire rope tensioning wheel 12, which can rotate in a first direction to tighten the steel wire rope 11; a flexible pull rope 4, the first end of which is fixed to each skylight, and the second end of which is fixed to the movable push rod 1; when the steel wire rope tensioning wheel 12 rotates in the first direction, the movable push rod 1 drives the flexible pull rope 4 to move along the direction in which the multiple server racks are arranged side by side, so that each skylight perpendicular to the top of the cold aisle rotates along the axis 8 to be parallel to the top of the cold aisle.

[0068] If the cold aisle controller experiences a power failure or the skylight magnetic malfunction causes the skylight to detach, automatic operation will be impossible. This application proposes a method to quickly close the detached skylight manually using a mechanical mechanism until a solution is found. This achieves rapid closure of the cold aisle, promptly restoring normal operation and avoiding the high-temperature risks associated with the server racks, ensuring the racks operate in a stable and safe environment.

[0069] Combination Figure 1 For example, on the left side of the fixed frame 6 of multiple skylights 3, 7, and 9 in the fixed cold aisle, a movable push rod 1 (the length depends on the length of the cold aisle) can be installed. A support can be installed at each end and the middle of the movable push rod 1 to prevent the movable push rod 1 from sagging during movement.

[0070] In one embodiment, each skylight includes a first sub-skylight and a second sub-skylight that are symmetrical about the axis. The first sub-skylight of one of the two adjacent skylights is provided with a fixed pulley on the skylight side that is parallel to and away from the axis. The first end of the flexible pull rope is fixed to the second sub-skylight of the other of the two adjacent skylights, and the second end of the flexible pull rope passes through the fixed pulley and is fixed to the movable push rod.

[0071] Combination Figure 1 and Figure 2 Skylights 3 and 7 are adjacent and symmetrical about axis 8, dividing them into two semi-windows. Skylight 3 includes a first sub-skylight 32 and a second sub-skylight 34, both symmetrical about axis 8. Skylight 7 includes a first sub-skylight 72 and a second sub-skylight 74, both symmetrical about axis 8.

[0072] The first sub-skylight 72 of skylight 7 has a fixed pulley 5 on its side parallel to and away from axis 8. The first end of the flexible pull rope 4 is fixed to the second sub-skylight 34 of skylight 3, and the second end of the flexible pull rope 4 passes through the fixed pulley 5 and is fixed to the movable push rod 1. When the movable push rod 1 moves forward in the direction shown by the arrow, the flexible pull rope 4 is tightened, and skylight 3 and skylight 7 rotate in opposite directions. Finally, the first sub-skylight 72 of skylight 7 and the second sub-skylight 34 of skylight 3 overlap at the crossbeam of the fixed frame 6.

[0073] Skylights 3 and 7 can each have a magnet in one and a notch in the other. The crossbeam of the fixing frame 6 has a magnetic attraction corresponding to the magnet's position. The positions of the magnet, the magnet itself, and the notch overlap after the first sub-skylight 72 and the second sub-skylight 34 of skylight 3 intersect. Therefore, when the magnet is energized, it holds the magnet, closing and fixing skylights 3 and 7 together, with their plane parallel to the top of the cooling aisle. If the skylight magnet is not energized due to a malfunction, the wire rope tightening wheel can be used to keep the skylight locked after it closes, preventing it from falling off again. Alternatively, a rotary lock can be installed at the corresponding position on the skylight fixing frame 6 to secure the currently closed skylight, keeping it closed even without the magnet. The skylight will remain closed until the magnet is energized, using magnetic force to maintain its closed state.

[0074] Optionally, a spring 102 is provided at the other end of the movable push rod 1, and the spring 102 pushes the movable push rod 1 to reset after the wire rope tensioning wheel 12 is released.

[0075] If the fault is cleared, the sunroof can be closed magnetically, which releases the wire rope tensioning wheel 12, and the movable push rod 1 engages with the spring 102. Figure 2 The system returns to its original position under the opposite force of the arrow, ready to quickly close the cooling aisle should the skylight detach again. Whether a single skylight or an entire row of skylights detaches, the skylights can be manually and mechanically closed using the above method until the magnetic attraction returns to normal, at which point the wire rope tensioning wheel 12 can be released. After releasing the wire rope tensioning wheel 12, the push rod 1 can be moved back to its original position under the tension of the spring 102. The ropes on each skylight are then relaxed, allowing the skylights to be opened again.

[0076] For example, when skylights 3 and 7 are open, both skylights are basically perpendicular to the top of the cold aisle, and the flexible pull ropes 4 installed on skylights 3 and 7 are basically taut. When skylights 3 and 7 are closed, the flexible pull ropes 4 are loose.

[0077] In this way, an alarm can be generated immediately when a skylight detaches, causing an abnormal cold aisle closure. This alerts maintenance personnel to respond quickly and easily, and allows for manual mechanical reclosing of the detached skylight until the magnetic energizing of the skylight is restored. This rapidly closes the cold aisle, ensuring the server racks operate in a stable and safe environment.

[0078] In this embodiment, by setting photoelectric switches and corresponding acquisition modules at both ends of the cold aisle formed by two adjacent cabinet groups, an alarm can be generated in time when any skylight falls off, reminding maintenance personnel to discover and quickly handle related problems. It has the advantages of simple structure, convenient operation and low manufacturing cost.
