Abstract
Description
A type of server rack
[0001] This application claims priority to Chinese Patent Application No. 202420853748.5, filed on April 23, 2024, entitled "A Server Room Cabinet", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of equipment room technology, and in particular to a server room cabinet. Background Technology
[0003] Fire protection measures for single-row micro-module cabinets (hereinafter referred to as cabinets) in data centers typically include: installing rack-mounted fire extinguishing racks inside the cabinets, setting up a separate control cabinet outside the cabinets to house fire extinguishing gas cylinders, and using cabinet fans to deliver fire extinguishing gas supplied by the computer room building into the cabinets.
[0004] Of the three fire-fighting measures mentioned above, the first one is costly and slow, the second one takes up server space and can increase costs, and the third one is difficult to guarantee the efficiency of fire-fighting gas intake.
[0005] Currently, some technologies are being modified to address the shortcomings of the first two fire-fighting measures and improve the air intake efficiency of the third method. For example, the cabinet door is equipped with an electromagnetic lock. After a fire alarm is triggered, the electromagnetic lock is de-energized, causing the cabinet door to open slightly. Maintenance personnel can then manually open the door, allowing the fire-fighting gas to circulate rapidly and in large quantities inside and outside the cabinet. While the aforementioned fire-fighting measures improve the air intake efficiency to some extent, they require manual operation of the cabinet door, posing a personal safety risk to maintenance personnel. Furthermore, the manual operation introduces a certain delay, hindering the timely effectiveness of the fire-fighting measures.
[0006] In conclusion, how to better utilize the fire-fighting gases in the computer room to protect the server racks from fire has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0040] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0041] Please refer to Figures 1 to 7. Figure 1 is a structural schematic diagram of the data center cabinet provided in the embodiment of this application in the first direction; Figure 2 is a structural schematic diagram of the lighting limit switch provided in the embodiment of this application; Figure 3 is a partial structural schematic diagram of the data center cabinet provided in the embodiment of this application at the pop-up door device; Figure 4 is a structural schematic diagram of the data center cabinet provided in the embodiment of this application in the second direction; Figure 5 is a structural schematic diagram of the data center cabinet provided in the embodiment of this application in the third direction; Figure 6 is a structural schematic diagram of the self-resetting limit switch provided in the embodiment of this application; Figure 7 is a structural schematic diagram of the data center cabinet provided in the embodiment of this application in the fourth direction.
[0042] Please refer to Figures 1 and 3. This application provides a data center cabinet, including a cabinet body 1 with a cabinet body 11 and a cabinet door 12, a smoke sensor disposed inside the cabinet body 11, an electric drive locking device disposed between the cabinet body 11 and the cabinet door 12, and a spring-loaded door device 3 disposed between the cabinet body 11 and the cabinet door 12. The aforementioned smoke sensor is disposed inside the cabinet body 11, specifically on the inner side of the top plate of the cabinet near the cabinet door 12, and is used to monitor the fire situation inside the cabinet body 11. It can send a signal when smoke appears inside the cabinet body 11. The aforementioned electric drive locking device is disposed between the cabinet body 11 and the cabinet door 12. It can be used to lock the cabinet body 11 and the cabinet door 12, so that the cabinet body 1 is in a closed state. Of course, it can also unlock the cabinet body 11 and the cabinet door 12, so that the cabinet body 1 is in an open state. The aforementioned spring-loaded door device 3 is disposed between the cabinet body 11 and the cabinet door 12. It can use its own elasticity to drive the cabinet body 11 and the cabinet door 12 to move relative to each other, so as to open the cabinet door 12.
[0043] In this embodiment, the cabinet body 1 includes a cabinet body 11 and a cabinet door 12. The cabinet door 12 is rotatably connected to the cabinet body 11. The pivot of the cabinet door 12 is distributed along the height direction of the cabinet body 1. For example, the cabinet body 1 is placed vertically in the computer room, and the aforementioned pivot is located on one side of the cabinet body 11 along the width direction. At the same time, the aforementioned pivot is vertically distributed. It can be seen that the cabinet door 12 can be opened and closed by rotating around the pivot relative to the cabinet body 11.
[0044] In this embodiment, the spring-loaded door device 3 is located between the cabinet body 11 and the cabinet door 12. It utilizes its own elasticity to drive the cabinet door 12 to rotate relative to the cabinet body 11 around a pivot, thereby opening and closing the cabinet door 12. The aforementioned spring-loaded door device 3 may include a mounting base 31 and an elastic energy storage portion 32 disposed on the mounting base 31. The mounting base 31 can slide along the width direction of the cabinet body 1 and be locked to either the cabinet body 11 or the cabinet door 12. The elastic energy storage portion 32 can abut against the other of the cabinet body 11 and the cabinet door 12. For example, the mounting base 31 can slide along the width direction of the cabinet body 1 and be connected to the cabinet body 11 and can be locked at any position along the sliding path. Simultaneously, one end of the elastic energy storage portion 32 is connected to the mounting base 31 and the other end abuts against the cabinet door 12. The elastic energy storage portion 32 is configured to be in a compressed energy storage state when the cabinet body 11 and the cabinet door 12 are locked together.
[0045] Since the mounting base 31 slides along the width direction of the cabinet body 1 and is locked to the cabinet body 11 or the cabinet door 12, and the pivot of the cabinet door 12 is distributed along the height direction of the cabinet body 1, the distance between the aforementioned mounting base 31 and the aforementioned pivot is adjustable.
[0046] Taking Figure 1 as an example, the vertical direction of Figure 1 represents the height of the cabinet body 1, and the horizontal direction represents the width of the cabinet body 1. The pivot is located on the right edge of the cabinet body 1, and the mounting base 31 is located between the cabinet body 11 and the cabinet door 12. Typically, the mounting base 31 is located at the top edge of the cabinet body 11. When the mounting base 31 slides to the right along the width direction of the cabinet body 1, the distance between the pop-up door device 3 and the pivot decreases; conversely, when the mounting base 31 slides to the left along the width direction of the cabinet body 1, the distance between the pop-up door device 3 and the pivot increases. In the aforementioned example, changing the distance between the pop-up door device 3 and the pivot can adjust the effect of the pop-up door device 3 on the cabinet door 12 when it opens the cabinet door 12. For example, when the distance between the spring-loaded door device 3 and the pivot is small, the spring force applied by the spring-loaded door device 3 to the cabinet door 12 results in a smaller opening range for the cabinet door 12. Conversely, when the distance between the spring-loaded door device 3 and the pivot is large, the spring force applied by the spring-loaded door device 3 to the cabinet door 12 results in a larger opening range for the cabinet door 12. Based on the aforementioned settings, the operator can adjust the installation position of the spring-loaded door device 3 according to the location of the cabinet body 1 and its cabinet door 12 to ensure that the cabinet door 12 can automatically open with an appropriate opening range under the action of the spring-loaded door device 3.
[0047] In this embodiment, a smoke sensor is located inside the cabinet body 11, and an electric locking device 2 is located between the cabinet body 11 and the cabinet door 12. The electric locking device 2 is configured to cut off power when the smoke sensor detects smoke. Furthermore, the electric locking device 2 is coupled to the smoke sensor. Therefore, when the smoke sensor detects smoke inside the cabinet body 11, the electric locking device 2 can perform a power-off operation based on the monitoring signal from the smoke sensor. After power-off, the electric locking device 2 releases the locking state of the cabinet body 11 and the cabinet door 12, allowing the cabinet body 11 and the cabinet door 12 to separate. Conversely, when the smoke sensor does not detect smoke inside the cabinet body 11, the electric locking device 2 is energized and can lock the cabinet body 11 and the cabinet door 12, preventing them from separating. As mentioned above, a spring-loaded door device 3 is provided between the cabinet body 11 and the cabinet door 12. Once the electric drive locking device 2 is de-energized, the spring-loaded door device 3, which was originally in a compressed and stored state, releases its spring force. This spring force can push the cabinet door 12 to rotate relative to the cabinet body 11, thereby opening the cabinet door 12. The electric drive locking device 2 can be an electromagnetic lock or other similar components.
[0048] In summary, the server rack provided in this application utilizes a smoke sensor, an electric locking device 2, and a spring-loaded door device 3 to achieve smoke detection and automatic door opening. This enables the rapid opening of the cabinet door 12 when smoke rises inside the cabinet body 11, facilitating the entry of fire-fighting gases and other fire-fighting materials into the cabinet body 11, controlling the smoke and fire situation of the server rack, and extinguishing the smoke and fire points of the server rack. The server rack provided in this application can flexibly adjust the specific installation position of the spring-loaded door device 3 on each cabinet body 1 according to parameters such as the specific distribution position of the cabinet body 1 in the server room, the relative positional relationship between different cabinet bodies 1, and the relative positional relationship between the cabinet body 1 and the fire-fighting equipment in the server room. This allows the spring-loaded door device 3 to drive the cabinet door 12 to open to a suitable degree, ensuring that fire-fighting gases and other fire-fighting materials enter the cabinet body 11, while also preventing the cabinet door 12 from colliding or rebounding due to excessive opening, avoiding affecting the actual opening effect of the cabinet door 12, avoiding noise, and avoiding damage to the cabinet door 12 or other equipment in the server room.
[0049] The data center cabinets provided in this application will be further described below with reference to the accompanying drawings and embodiments.
[0050] Please refer to Figures 1 and 5. In some embodiments, the server rack provided in this application also includes a rack lock 5. The rack lock 5 is located between the rack body 11 and the rack door 12, and is used to control the power-on and power-off states of the electric drive locking device 2. In other words, the electric drive locking device 2 is connected to the rack lock 5, and the electric drive locking device 2 is configured to de-energize when the rack lock 5 is opened. In this embodiment, the operator can manually adjust the power-on and power-off states of the electric drive locking device 2 using the rack lock 5. For example, when the entire server rack is normally powered on, when the operator opens the rack lock 5, the rack lock 5 de-energizes the electric drive locking device 2. After the electric drive locking device 2 is de-energized, it releases the locking state of the rack body 11 and the rack door 12, allowing the rack body 11 and the rack door 12 to separate from each other. Conversely, when the operator does not operate the rack lock 5, the electric drive locking device 2 is not controlled by the rack lock 5, and the power-on and power-off states of the electric drive locking device 2 depend on the monitoring signal of the smoke sensor.
[0051] In the above embodiment, the electric locking device 2 can be powered by the sunroof control box; the aforementioned sunroof control box is linked with the smoke sensor. When the smoke sensor transmits a fire alarm signal to the sunroof control box, the relay in the sunroof control box will cut off the circuit of the electric locking device 2, thereby realizing remote automatic door opening.
[0052] In the above embodiments, the cabinet door 12 of the server room cabinet can be opened in two ways: First, the electric drive locking device 2 and the spring-loaded door device 3 automatically open the cabinet door 12 based on the monitoring signal of the smoke sensor; second, the operator manually operates the cabinet lock 5 to cut off the power to the electric drive locking device 2, and then the spring-loaded door device 3 opens the cabinet door 12, or the spring-loaded door device 3 and the operator open the cabinet door 12 together. Obviously, when smoke or fire starts inside the cabinet body 11, the cabinet door 12 of the server room cabinet will automatically open in the first way mentioned above, which facilitates the fire-fighting equipment in the server room to extinguish the smoke and fire in the cabinet body 11 and its components; when there is no smoke or fire inside the cabinet body 11, the cabinet door 12 of the server room cabinet will be manually opened in the second way mentioned above, which facilitates the operator to observe and maintain the cabinet body 11 and its components.
[0053] Based on the above embodiments, the server rack provided in this application also includes a lighting device. The lighting device is installed inside the rack body 11 and is linked to the rack lock 5 switch. The lighting device is configured to provide power and illumination when the rack lock 5 is open. Specifically, the linkage between the lighting device and the rack lock 5 switch means that the lighting device is configured to turn on when the rack lock 5 is open and turn off when the rack lock 5 is closed. Based on the aforementioned linkage between the lighting device and the rack lock 5, when an operator manually opens the rack door 12, the rack lock 5 can not only de-energize the electric drive locking device 2 but also turn on the lighting device, providing illumination to the interior of the rack body 11, facilitating the operator's observation and maintenance of the components inside the rack body 11.
[0054] In the above embodiments, the lighting device can be linked not only to the cabinet lock 5 but also to the electric drive locking device 2. For example, the lighting device is configured to close when the electric drive locking device 2 is powered on and open when the electric drive locking device 2 is de-powered. Based on the aforementioned linkage between the lighting device and the electric drive locking device 2, regardless of whether the cabinet door 12 is opened using the first or second opening method mentioned above, the lighting device will turn on when the cabinet door 12 is opened, providing illumination to the interior of the cabinet body 11.
[0055] Referring to Figures 1 and 2, in order to enable the lighting device to be linked with the cabinet lock 5 or the electric drive locking device 2, the cabinet door 12 can be equipped with a lighting limit switch 6. The lighting limit switch 6 can be connected to the cabinet lock 5 or the electric drive locking device 2. When the cabinet door 12 is opened, the lighting limit switch 6 is turned on, and the lighting device, such as a lamp, is powered on. When the cabinet door 12 is closed, the lighting limit switch 6 is turned off, and the lamp is powered off.
[0056] The lighting fixtures can serve both the initial server mounting and the subsequent operation and maintenance of the server rack. The specific structure of the lighting fixtures can refer to relevant settings in existing technologies. The specific installation location of the lighting fixtures inside the cabinet 11 includes, but is not limited to, the internal top surface of the cabinet 11. Depending on the actual installation location of various electrical components inside the cabinet 11, the lighting fixtures can also be installed on the internal rear side, internal left and right sides, etc. of the cabinet 11.
[0057] Referring to Figures 1 and 6, based on some of the embodiments provided above, the server rack provided in this application also includes a self-resetting limit switch 7; the self-resetting limit switch 7 is located between the cabinet body 11 and the cabinet door 12, and the electric drive locking device 2 is connected to the cabinet lock 5 through the self-resetting limit switch 7.
[0058] The self-resetting limit switch 7 is located between the cabinet body 11 and the cabinet door 12. Simultaneously, the self-resetting limit switch 7 is located between the cabinet lock 5 and the electric drive locking device 2. The cabinet lock 5, the self-resetting limit switch 7, and the electric drive locking device 2 are connected by a transmission mechanism. The operator can activate the self-resetting limit switch 7 through the cabinet lock 5, thereby de-energizing the electric drive locking device 2. For the specific structure of the self-resetting limit switch 7 and the specific connection method of the cabinet lock 5, the self-resetting limit switch 7, and the electric drive locking device 2, please refer to Figure 6 or relevant settings in existing technology.
[0059] Referring to Figures 1 to 5, in some embodiments, the server rack provided in this application includes a rack body 11 and a rack door 12. The rack door 12 is provided with a handle 4, which is connected to a rack lock 5 and used to operate the rack lock 5. Typically, the handle 4 and the rack lock 5 are located on the inner and outer sides of the rack door 12, respectively. For example, the handle 4 is located on the outer side of the rack door 12, and the rack lock 5 is located on the inner side of the rack door 12. Operators can use the handle 4 to drive the rack lock 5 to open and close. In this embodiment, the handle 4 serves as both an input to the rack lock 5, facilitating operation of the rack lock 5 located on the inner side of the rack door 12, and an auxiliary structure for pushing and pulling the rack door 12, facilitating rotation of the rack door 12 around a pivot. In the aforementioned example, when the rack lock 5 is driven by the handle 4, the operating principle of the handle 4 includes, but is not limited to, rotation and pressing.
[0060] As shown in Figure 1, based on the above embodiments, the server rack provided in this application is equipped with a rack lock 5 and two electric drive locking devices 2; the two electric drive locking devices 2 are located between the rack body 11 and the rack door 12 and are respectively located at both ends of the rack door 12 along the height direction; the rack lock 5 is located in the middle of the rack door 12 along the height direction. In the aforementioned example, the rack body 11 and the rack door 12 are locked to each other by the two electric drive locking devices 2, which is compatible with the shape and size of the common rack body 1, and can ensure the locking effect of the electric drive locking devices 2 on the rack body 11 and the rack door 12; in the aforementioned example, viewed along the height direction of the rack body 1, the rack lock 5 is located between the two electric drive locking devices 2, which is compatible with the relative height of the operator and the rack body 1, making it convenient for the operator to operate the rack lock 5 or the handle 4 connected to the rack lock 5.
[0061] In some embodiments, the server rack is provided with a spring-loaded door device 3, which includes a mounting base 31 and an elastic energy storage unit 32. Referring to Figures 1 and 3, the elastic energy storage unit 32 may include torsion springs. Typically, the elastic energy storage unit 32 includes multiple torsion springs, which are arranged side by side between the rack body 11 and the rack door 12; in other words, these torsion springs are connected in parallel.
[0062] In addition, in some embodiments, the server rack provided in this application also includes a cabinet door limiting device for maintaining the maximum opening of the cabinet door 12; the cabinet door limiting device is disposed between the cabinet body 11 and the cabinet door 12. When the cabinet door 12 is opened to the maximum opening, the cabinet door limiting device connects to the cabinet door 12 and maintains the current opening of the cabinet door 12, preventing the cabinet door 12 from shaking and avoiding noise or affecting the actual opening of the cabinet door 12 due to shaking.
[0063] The aforementioned cabinet door limiting device can utilize magnetic attraction, negative pressure attraction, and latching force to position the cabinet door 12 to its maximum opening. For example, the cabinet door limiting device is located on the outside of the cabinet body 1 and on the cabinet body 11. Simultaneously, the cabinet door limiting device is located at one end of the cabinet door 12's rotation trajectory. When the cabinet door 12 rotates open relative to the cabinet body 11 around its pivot axis, the cabinet door 12 gradually approaches the cabinet door limiting device along its rotation trajectory. Once the cabinet door 12 rotates to its maximum opening, the cabinet door 12 and the cabinet door limiting device come into contact with each other. The cabinet door limiting device can magnetically attract the cabinet door 12, preventing the cabinet door 12 from continuing to rotate, thus maintaining the current opening of the cabinet door 12. Of course, in the aforementioned embodiment, the cabinet door limiting device has magnetic attraction properties, and the cabinet door 12 is provided with a magnetic attraction part that matches the cabinet door limiting device.
[0064] Referring to Figures 5 and 7, in some embodiments, the server room cabinet provided in this application includes a cabinet body 11 and a cabinet door 12. The cabinet body 11 is equipped with a guide fan, which can drive gas to flow in and out of the cabinet body 11. For example, the guide fan can drive the fire-fighting gas in the server room to flow in and out of the cabinet body 11, ensuring that the fire-fighting gas can flow into and out of the cabinet body 1 efficiently and quickly after the cabinet door 12 is opened, so as to control the smoke or fire in the cabinet body 1.
[0065] In the above embodiments, the airflow fan may include an intake fan and an exhaust fan; the intake fan and the exhaust fan have opposite airflow directions. For example, the intake fan is configured to draw gas into the cabinet 11, and the exhaust fan is configured to exhaust the gas inside the cabinet 11 outwards. Taking Figure 1 as an example, the vertical direction of Figure 1 represents the height of the cabinet body 1, and the horizontal direction of Figure 1 represents the width direction of the cabinet body 1. The pivot is located on the right edge of the cabinet body 1. In the aforementioned example, the intake fan is close to the pivot, which is beneficial for drawing as much external gas, such as fire-fighting gas, as possible into the right-side cavity inside the cabinet body 11 when the cabinet door 12 is not fully open, thus avoiding affecting the fire-fighting effect inside the cabinet body 11 due to insufficient opening of the cabinet door 12. At the same time, the exhaust fan is far from the pivot, which is beneficial for allowing external gas, such as fire-fighting gas, to fully diffuse inside the cabinet body 11 before being discharged. The reasons for insufficient opening of the cabinet door 12 include, but are not limited to, abnormalities in the spring-loaded door device 3, abnormalities in the connection between the cabinet door 12 and the cabinet body 11, and special distribution positions of the cabinet body 1 in the computer room.
[0066] Based on the above embodiments, as shown in Figure 7, the cabinet body 11 is provided with an exhaust mesh plate; the exhaust mesh plate has holes, which can provide a certain degree of air circulation to the cabinet body 1 when the cabinet door 12 is not opened, so as to dissipate heat and cool down the cabinet body 1, and can also improve the flow performance of fire-fighting gas inside and outside the cabinet body 1 when the cabinet door 12 is opened.
