Description
Technical Field
[0001] This utility model relates to the field of data center infrastructure technology, specifically to a sliding door for hot and cold aisles in a computer room. Background Technology
[0002] With the rapid development of cloud computing and big data technologies, data center computer rooms commonly adopt hot and cold aisle layouts to optimize airflow and reduce energy consumption. As a key isolation component of hot and cold aisles, the condensate treatment capacity and sealing reliability of sliding doors directly affect the energy efficiency of the computer room and the operational stability of equipment.
[0003] According to a public announcement (Publication No.: CN219773969U), an automatic sliding door suitable for computer room passageways includes: two door frame skeletons and a top beam. The two door frame skeletons are symmetrically spaced and installed at intervals on the front face of the computer room, forming an open area between them. The top beam is installed across the top of the two door frame skeletons. This utility model utilizes sliding door panels to seal the open area formed between the two door frame skeletons, ensuring the airtightness of the computer room. By concealing a door closing component on the top beam and covering it with a decorative cover, the overall aesthetics of the sliding door are improved. Simultaneously, the door closing component enables the synchronized automatic closing of the two sliding door panels after opening, eliminating the need for an external power source or manual closing, saving time and effort, and is energy-efficient and environmentally friendly. It also prevents the problem of cold air leakage in the computer room due to staff forgetting to close the door, thus avoiding resource waste.
[0004] In the aforementioned application, the door closing component can automatically and synchronously close the double sliding door panels after they have been opened, without the need for an external power source or manual closing. However, fluctuations in the air humidity in the computer room can easily cause condensation on the surface of the sliding door. Existing dehumidification devices are mostly single-point manual scraping or natural diversion. Therefore, we propose a sliding door for hot and cold aisles in computer rooms. Utility Model Content
[0005] To overcome the above-mentioned defects, this utility model provides a sliding door for hot and cold aisles in computer rooms, which solves the technical problems of inefficient condensate removal, sealing failure and high maintenance costs in the prior art.
[0006] According to one aspect, at least one embodiment of the present invention provides a sliding door for a hot and cold aisle in a computer room, comprising: a sealing plate outer frame, a sliding door slidably connected to the inner wall of the sealing plate outer frame, a skylight switch and a lighting switch provided on the side of the sealing plate outer frame, a lower cover fixedly connected to the side of the sealing plate outer frame, a column fixedly connected to the top of the lower cover, an upper cover fixedly connected to one end of the column, a reversing skylight fixedly connected to the top of the upper cover, and a water removal device provided on the side of the sliding door; The dewatering device includes a motor base, the side of which is fixedly connected to the side of the sealing plate frame. A motor is fixedly connected to the top of the motor base. The output end of the motor passes through and is rotatably connected to the top of the motor base. A drive pulley one is fixedly connected to the output end of the motor. A drive pulley two is fixedly connected to the circumferential surface of the motor output shaft. A pulley shaft one and a pulley shaft two are rotatably connected to the bottom of the motor base. A belt one is provided on the circumferential surface of drive pulley one. Drive pulley one is driven and connected to pulley shaft one through belt one. A belt two is provided on the circumferential surface of drive pulley two. Drive pulley two is driven and connected to pulley shaft two through belt two. A threaded rod is provided at the bottom of the motor base. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A dewatering scraper is fixedly connected to the circumferential surface of the threaded sleeve. The side of the dewatering scraper is in contact with the side of the sliding door.
[0007] For example, in at least one embodiment of this utility model, a sliding door for hot and cold aisles in a computer room further includes: two threaded rods, one end of which is fixedly connected to one end of pulley shaft one and one end of pulley shaft two. The double threaded rod design allows the dewatering scraper to rise and fall synchronously on both sides of the sliding door, resulting in balanced force and improved reliability of the dewatering device.
[0008] The first and second pulley shafts are symmetrical about each other along the vertical central axis of the motor, and the diameter of the first pulley shaft is equal to the diameter of the second pulley shaft. The symmetry and equal diameter of the first and second pulley shafts along the central axis of the motor ensure consistent transmission ratios in the dual-drive system, avoiding asynchronous speeds or belt slippage caused by differences in shaft diameters.
[0009] The diameter of the threaded sleeve's displacement trajectory is equal to the height of the sliding door, and the width of the dewatering scraper is equal to half the width of the sliding door. The threaded sleeve's displacement trajectory is aligned with the height of the sliding door, allowing the dewatering scraper to cover the entire height of the sliding door and thoroughly remove condensation from the door surface.
[0010] The bottom of the dewatering scraper is equipped with a water collection trough, the width of which is equal to the width of the scraper. This integrated water collection trough at the bottom of the scraper allows for real-time collection of condensate, preventing water droplets from falling directly onto the machine room floor or equipment surface and maintaining a dry environment in the passageway.
[0011] According to another aspect, at least one embodiment of the present invention also provides a sliding door for hot and cold aisles in a computer room, comprising: a sealing device, the sealing device including a sealing strip, the sealing strip being disposed on the side of the sliding door, a transmission rod first fixedly connected to the side of the sealing strip, a transmission plate rotatably connected to one end of the transmission rod first, an eccentric rod rotatably connected to one end of the transmission plate, a gear fixedly connected to one end of the eccentric rod, a support shaft rotatably connected to the inner wall of the gear, one end of the support shaft fixedly connected to the side of the sealing plate outer frame, a transmission shaft second fixedly connected to the side of the sliding door, a rack fixedly connected to one end of the transmission shaft second, a groove provided on the side of the rack, a support rod slidably connected to the inner wall of the groove, and one end of the support rod fixedly connected to the side of the sliding door.
[0012] For example, in at least one embodiment of this utility model, a sliding door for a hot and cold aisle in a computer room further includes: two sealing devices symmetrically arranged along the vertical central axis of the sliding door, with the rack and gear meshing with each other. The sealing devices are symmetrically arranged on both sides of the sliding door, forming a double-sealing structure, thus reducing air conditioning energy consumption.
[0013] The diameter of the sealing strip is equal to half the width of the sliding door, and the sealing strip is located at the bottom of the sliding door. The sealing strip diameter matching half the width of the sliding door and its location at the bottom of the door specifically addresses the problems of water ingress and air leakage at the bottom of the hot and cold aisles in the computer room.
[0014] When the support rod is located at one end of the slide groove, the top of the sealing strip is in contact with the side of the outer frame of the sealing plate. When the support rod is located at the end of the slide groove, the top of the sealing strip is in close contact with the outer frame of the sealing plate, forming a dual guarantee of mechanical limiting and elastic sealing.
[0015] The sealing strip is rotatably connected to a pivot at one end near the outer frame of the sealing plate, and the pivot is fixedly connected to the side of the outer frame of the sealing plate. The sealing strip is connected to the door frame via the pivot, ensuring that the displacement trajectory of the sealing device is unique and improving the reliability and stability of the sealing device.
[0016] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, the water removal device achieves efficient removal and diversion of condensate on the surface of the sliding door through a synchronous drive of double threaded rods and a symmetrical pulley shaft design. The two threaded rods are respectively connected to pulley shaft one and pulley shaft two, which rotate synchronously under the drive of the motor, ensuring that the water removal scraper scrapes back and forth along the entire height range of the sliding door, without any dead corners in cleaning. The width of the scraper is set to half the width of the door to avoid uneven force or jamming caused by single drive. The equal-width water collection tank integrated at the bottom collects the scraped condensate in real time.
[0017] 2. In this utility model, the sealing device, through its symmetrical layout, mechanical limiting, and rotating shaft connection structure, significantly improves the airtightness and sealing reliability of the hot and cold passages. Two symmetrically arranged sealing devices simultaneously counteract the lateral force during door opening and closing, ensuring the sealing strip evenly adheres to the outer frame of the sealing plate, reducing hot and cold air leakage, lowering air conditioning energy consumption, and ensuring the bottom sealing strip diameter matches half the door width to meet the sealing requirements of raised floor air supply passages.

[0027] like Figures 1-5This invention illustrates a sliding door for a hot and cold aisle in a computer room according to one embodiment of the present invention, comprising: a sealing plate outer frame 1, a sliding door 2 slidably connected to the inner wall of the sealing plate outer frame 1, a skylight switch 3 and a lighting switch 4 provided on the side of the sealing plate outer frame 1, a lower cover 5 fixedly connected to the side of the sealing plate outer frame 1, a column 6 fixedly connected to the top of the lower cover 5, an upper cover 7 fixedly connected to one end of the column 6, a reversing skylight 8 fixedly connected to the top of the upper cover 7, and a water removal device 9 provided on the side of the sliding door 2; The dewatering device 9 includes a motor base 901, the side of which is fixedly connected to the side of the sealing plate outer frame 1. A motor 902 is fixedly connected to the top of the motor base 901. The output end of the motor 902 passes through and is rotatably connected to the top of the motor base 901. A first drive pulley 903 is fixedly connected to the output end of the motor 902, and a second drive pulley 904 is fixedly connected to the circumferential surface of the output shaft of the motor 902. The bottom of the motor base 901 is rotatably connected to a pulley shaft 1 905 and a pulley shaft 2 906. A belt 1 907 is provided on the circumferential surface of the drive pulley 1 903. The drive pulley 1 903 is connected to the pulley shaft 1 905 through the belt 1 907. A belt 2 908 is provided on the circumferential surface of the drive pulley 2 904. The drive pulley 2 904 is connected to the pulley shaft 2 906 through the belt 2 908. A threaded rod 909 is provided at the bottom of the motor base 901. A threaded sleeve 910 is threadedly connected to the circumferential surface of the threaded rod 909. A water-removing scraper 911 is fixedly connected to the circumferential surface of the threaded sleeve 910. The side of the water-removing scraper 911 is in contact with the side of the sliding door 2.
[0028] In some examples, there are two threaded rods 909, one end of which is fixedly connected to one end of pulley shaft 905 and one end of pulley shaft 906. The double threaded rod 909 design allows the water removal scraper 911 to rise and fall synchronously on both sides of the sliding door 2, resulting in balanced force and improving the reliability of the water removal device 9.
[0029] Pulley shaft 1 (905) and pulley shaft 2 (906) are symmetrical about each other along the vertical central axis of motor 902, and the diameter of pulley shaft 1 (905) is equal to the diameter of pulley shaft 2 (906). The symmetry and equal diameter of pulley shaft 1 (905) and pulley shaft 2 (906) along the central axis of motor 902 ensure consistent transmission ratios in the dual-drive system, avoiding asynchronous speeds or belt slippage caused by differences in shaft diameters.
[0030] The diameter of the displacement trajectory of the threaded sleeve 910 is equal to the height of the sliding door 2, and the width of the water-removing scraper 911 is equal to half the width of the sliding door 2. The displacement trajectory of the threaded sleeve 910 is consistent with the height of the sliding door 2, so that the water-removing scraper 911 can cover the entire height range of the sliding door 2 and thoroughly remove condensate from the door surface.
[0031] The bottom of the water removal scraper 911 is equipped with a water collection trough, the width of which is equal to the width of the water removal scraper 911. The water removal scraper 911 integrates a water collection trough of equal width at the bottom, which can collect the scraped condensate in real time, preventing water droplets from dripping directly onto the machine room floor or equipment surface, and keeping the passageway dry.
[0032] For example, such as Figures 1-5 When condensation occurs on the surface of the sliding door 2 in the hot and cold aisle of the machine room due to temperature difference, the staff activates the dewatering device 9. After the motor 902 is powered on, the output end drives the first drive pulley 903 and the second drive pulley 904 to rotate synchronously. Through the first belt 907 and the second belt 908, the pulley shaft 905 and the pulley shaft 906 are driven to rotate respectively. The threaded rod 909 at the end of the pulley shaft 905 and the pulley shaft 906 rotates with the shaft. The threaded sleeve 910 moves up and down along the threaded trajectory of the threaded rod 909, which drives the dewatering scraper 911 fixed on the threaded sleeve 910 to rise and fall synchronously. The width of the dewatering scraper 911 is half the width of the sliding door 2. Driven by the double threaded rod 909, it scrapes back and forth from the middle of the door to both sides or from both sides to the middle to remove the condensation on the surface of the door. The scraped water is collected along the equal-width water collection trough at the bottom of the scraper.
[0033] like Figures 1-5 This illustration shows a sliding door for a hot and cold aisle in a computer room, according to another embodiment of the present invention. The door includes a sealing device 10, comprising a sealing strip 1001 disposed on the side of the sliding door 2. A transmission rod 1002 is fixedly connected to the side of the sealing strip 1001. One end of the transmission rod 1002 is rotatably connected to a transmission plate 1003. One end of the transmission plate 1003 is rotatably connected to an eccentric rod 1004. One end of the eccentric rod 1004 is fixedly connected to... Gear 1005, with a support shaft 1006 rotatably connected to the inner wall of gear 1005. One end of the support shaft 1006 is fixedly connected to the side of the outer frame 1 of the sealing plate. A second transmission shaft 1007 is fixedly connected to the side of the sliding door 2. A rack 1008 is fixedly connected to one end of the second transmission shaft 1007. A groove 1009 is provided on the side of the rack 1008. A support rod 1010 is slidably connected to the inner wall of the groove 1009. One end of the support rod 1010 is fixedly connected to the side of the sliding door 2.
[0034] In some examples, two sealing devices 10 are provided, symmetrically arranged along the vertical central axis of the sliding door 2, with rack 1008 and gear 1005 meshing with each other. The sealing devices 10 are symmetrically arranged on both sides of the sliding door 2, forming a double-sealing structure, which reduces air conditioning energy consumption.
[0035] The diameter of the sealing strip 1001 is equal to half the width of the sliding door 2, and the sealing strip 1001 is located at the bottom of the sliding door 2. The sealing strip 1001, with its diameter matching half the width of the sliding door 2 and located at the bottom of the door, specifically addresses the problem of water ingress and air leakage at the bottom of the hot and cold aisles in the computer room.
[0036] When the support rod 1010 is located at one end of the slide groove 1009, the top of the sealing strip 1001 is in contact with the side of the sealing plate outer frame 1. When the support rod 1010 is located at the end of the slide groove 1009, the top of the sealing strip 1001 is in close contact with the sealing plate outer frame 1, forming a dual guarantee of mechanical limiting and elastic sealing.
[0037] The sealing strip 1001 is rotatably connected to a pivot at one end near the outer frame 1 of the sealing plate, and the pivot is fixedly connected to the side of the outer frame 1 of the sealing plate. The sealing strip 1001 is connected to the door frame through the pivot, ensuring that the displacement trajectory of the sealing device 10 is unique and improving the reliability and stability of the sealing device 10.
[0038] For example, such as Figures 1-5 When the sliding door 2 is opened or closed, the sealing device 10 achieves dynamic sealing through mechanical linkage. When the sliding door 2 slides, the transmission shaft 1007 fixed on its side drives the rack 1008 to move synchronously. The rack 1008 meshes with the gear 1005, driving the gear 1005 to rotate around the support shaft 1006. When the gear 1005 rotates, the eccentric rod 1004 rotates accordingly, pulling the transmission rod 1002 through the transmission plate 1003, causing the sealing strip 1001 to adhere to or move away from the outer frame 1 of the sealing plate. When the sliding door 2 is closed, the support rod 1010 slides to the end of the groove 1009 of the rack 1008, and the mechanical limit makes the top of the sealing strip 1001 in close contact with the outer frame 1 of the sealing plate.
[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
