Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold aisle technology, specifically a cold aisle enclosure structure for data center cabinets. Background Technology
[0002] As IT equipment increasingly moves towards high-density centralized management, the heat dissipation problem faced by data centers is becoming more and more serious. Cold / hot aisle containment systems are energy-saving technologies used to improve the efficiency of data center cooling systems and reduce "hot spots" generated by the heat generated by high-power IT equipment. They are primarily used in data center server rooms. Data center server rooms generally face problems such as high equipment heat density, high power consumption, and insufficient space in server rooms and racks. The proper use of cold aisle solutions can significantly improve the heat dissipation capacity of data centers and make full and effective use of rack and server room space.
[0003] In the prior art, such as Chinese Patent Publication No. CN219042260U, a cold aisle enclosure structure for data center cabinets is disclosed, including cabinet rows. The front and rear ends of the two cabinet rows are provided with fixing plates. The top adjacent sides of the two cabinet rows are fixedly connected with sealing fasteners. The middle position of the opposite side of the two sealing fasteners is provided with a T-shaped groove. The top adjacent sides of the two sealing fasteners are provided with a sliding groove.
[0004] The aforementioned patented technology can ensure the airtightness of the cold aisle of the cabinet, avoiding leakage problems. It is also relatively easy to use to seal the aisle with this kind of sealing fastener. However, in actual use, multiple cabinets are usually combined. Since there is no good sealing structure between the cabinets, the cold air inside the cold aisle can easily leak from the gaps in the cabinet, thus affecting the heat dissipation effect of the cabinet. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a closed cold aisle structure for data center cabinets, solving the problems mentioned in the background section.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1
[0026] like Figures 1-7As shown, this utility model provides a technical solution: a cold aisle enclosure structure for a data center cabinet, including a cold aisle body 1, a cabinet 2, and an enclosure plate 3. The outer walls of the cabinet 2 are provided with slots 201 on both sides. Sealing plates 31 are fixedly connected to the upper and lower ends of the enclosure plate 3. A cavity 301 is provided inside the enclosure plate 3. A rotating rod 32 is rotatably mounted on the surface of the enclosure plate 3. A sliding rod 33 is slidably mounted inside the rotating rod 32. An elliptical cylinder 34 is fixedly mounted on the surface of the rotating rod 32. Two pulleys 35 are fixedly mounted on the surface of the rotating rod 32. A positioning block 36 is fixedly mounted inside the cavity 301. One end of the rotating rod 32 is rotatably mounted inside the positioning block 36. A first rotating shaft 4 and a second rotating shaft 5 are rotatably mounted inside the cavity 301. An elliptical cylinder 41 and a pulley 42 are fixedly connected to the surface of the first rotating shaft 4. The surface of the second rotating shaft 5... Elliptical cylinder 34 and pulley 352 are fixedly connected to the cavity 301. Four first mounting plates 6 and two second mounting plates 7 are slidably installed inside the cavity 301. A sealing block 61 is fixedly connected to one side of the first mounting plate 6 and a locking block 71 is fixedly connected to one side of the second mounting plate 7. A connecting block 8 is fixedly connected to the rear end of the rotating rod 32. A hollow cylinder 9 is fixedly installed at one end of the inner wall of the cavity 301. Two pulleys 35 are located on both sides of the elliptical cylinder 34. The two pulleys 35 are connected to the pulley 42 and the elliptical cylinder 35 with belts. A spring 62 is fixedly connected to one side of the first mounting plate 6. The other end of the spring 62 abuts against the inner wall of the cavity 301. One end of the sealing block 61 slides to the outside of the sealing plate 3. The top of the outer wall of the first mounting plate 6 abuts against the side of the elliptical cylinder 41.
[0027] In this embodiment, the sealing plates 31 installed at the upper and lower ends of the sealing plate 3 can improve the sealing performance of the cold aisle body 1. The two pulleys 35 are connected to pulleys 42 and 52 respectively, so that the rotating rod 32 can drive the first rotating shaft 4 and the second rotating shaft 5 to rotate. The positioning block 36 can ensure that the position and angle of the rotating rod 32 are fixed and prevent it from moving during rotation. Elliptical cylinders 41 and 51 abut against the top and bottom of the outer wall of the first mounting plate 6 respectively, so that when the first rotating shaft 4 and the second rotating shaft 5 rotate, they can push the first mounting plates 6 on both sides to slide outward. The sealing blocks 61 at both ends move outward and fit against the outer wall of the cabinet 2, which can fill and seal the gap between the two cabinets 2. The spring 62 can make the first mounting plate 6 and the sealing block 61 move back automatically when the rotating rod 32 is reset, so as to facilitate the removal of the sealing plate 3.
[0028] Example 2
[0029] like Figures 1-7As shown, a second spring 72 is fixedly connected to one side of the second mounting plate 7, and the other end of the second spring 72 abuts against the inner wall of the cavity 301. One end of the locking block 71 slides to the outside of the closed plate 3. One side of the second mounting plate 7 abuts against one side of the elliptical cylinder 34. The shape of the locking block 71 matches the shape of the slot 201. One end of the sliding rod 33 extends and is disposed on the surface of the rotating rod 32. The other end of the sliding rod 33 extends and is disposed inside the connecting block 8. A ratchet 81 is fixedly connected to the rear end of the connecting block 8. A third spring 91 is fixedly installed inside the hollow cylinder 9. A sliding block 92 is fixedly connected to the surface of the third spring 91. A second ratchet 93 is fixedly connected to the surface of the sliding block 92. The rear end of the connecting block 8 and the surface of the sliding block 92 mesh with each other.
[0030] In this embodiment, the two sides of the elliptical cylinder 34 abut against the second mounting plates 7 at both ends, so that when the rotating rod 32 rotates, it can simultaneously push the second mounting plates 7 at both ends outward, thereby causing the locking blocks 71 on the side of the second mounting plates 7 to move outward and embed into the slots 201, so that the enclosure plate 3 can be installed and connected to the cabinet 2, and the position of the enclosure plate 3 can be positioned. The spring 72 can cause the locking blocks 71 to move back automatically when the rotating rod 32 is reset. The locking blocks 71 can release the limiting fixation of the enclosure plate 3 by moving out of the slots 201, so as to facilitate the removal of the enclosure plate 3 later. The connecting block 8 and the sliding block 92 are connected by ratchet 81 and ratchet 93. The connection is made so that, due to the characteristics of ratchet 81 and ratchet 93, they can only rotate in one direction. This allows the rotating rod 32 to be automatically fixed after adjusting the angles of elliptical cylinder 34, elliptical cylinder 41, and elliptical cylinder 51, preventing the rotation of the rotating rod 32 from affecting the sealing performance between the sealing block 61 and the cabinet 2. One end of the sliding rod 33 is located inside the connecting block 8, so that pressing the sliding rod 33 on the surface of the rotating rod 32 can push the sliding block 92 to move. The separation of the connecting block 8 and the sliding block 92 can release the one-way limit on the rotating rod 32. The spring 91 can make the ratchet 81 and ratchet 93 mesh tightly, improving the stability of the connection between the connecting block 8 and the sliding block 92.
[0031] Working principle: By filling the gap between the two cabinets 2 with the sealing plate 3, the rotating rod 32 drives the elliptical cylinder 34, pulley 35, first shaft 4 and second shaft 5 to rotate respectively. The elliptical cylinders 41 and 51 on the surfaces of the first shaft 4 and second shaft 5 rotate and squeeze the first mounting plate 6 on both sides, causing the first mounting plate 6 and the sealing block 61 to move outward. The sealing blocks 61 on both sides of the sealing plate 3 are respectively attached to the outer walls of the cabinets 2 at both ends. At the same time, the sealing plate 31 seals the upper and lower ends of the sealing plate 3, thereby filling and sealing the gap between the two cabinets 2. Meanwhile, the elliptical cylinder 34 pushes the gap when it rotates. The second mounting plate 7 and the locking block 71 are moved outward, so that the locking block 71 is embedded in the locking groove 201 opened on the side of the cabinet 2, thereby fixing the position of the sealing plate 3. When the rotating rod 32 rotates, it can drive the connecting block 8 to rotate. Through the meshing of ratchet 1 81 and ratchet 2 93, it can prevent the rotating rod 32 from rotating and affecting the stability of the sealing block 61 and the locking block 71 during use. When the sliding rod 33 is pushed to move, one end of the sliding rod 33 pushes up the sliding block 92 to move. At this time, the connecting block 8 and the sliding block 82 move away from each other. Then the rotating rod 32 can be rotated to reset the sealing block 61 and the locking block 71, thereby allowing the sealing plate 3 to be removed from the middle of the cabinet 2.
