Description

Technical Field

[0001] This utility model relates to the field of data center micro-modules, specifically a cold aisle structure for data center micro-modules with a maintenance window. Background Technology

[0002] The cold aisle of a data center micro-module is a key structure designed to optimize cooling efficiency. By efficiently sealing cold air within the aisle and precisely delivering it to the air inlet of the server rack, it effectively reduces the mixing of hot and cold air, thereby significantly reducing energy consumption.

[0003] Traditional data center cold aisle systems typically employ a fixed installation architecture: first, the skylight platform is fixed to the top of the server rack, and then the self-resetting skylight assembly or functional skylight assembly is fixed to the platform. However, this traditional installation method reveals shortcomings in adaptability and flexibility in practical applications:

[0004] Firstly, when installing the skylight mounting plate, it is impossible to operate inside the cold aisle; a ladder must be used to climb from the outside to the top of the cabinet. Due to the limited space in some projects, installers cannot operate upright and can only work by bending over or squatting, which not only significantly reduces work efficiency and increases labor intensity, but also directly affects installation accuracy and overall construction progress.

[0005] Secondly, during the installation of the skylight support plate on the top of the server rack, installers may step on the top plate area of ​​the rack, causing local deformation and thus damaging the visual aesthetics of the top of the rack.

[0006] Thirdly, similar operations are required for wiring connections (cabinet, skylight, monitoring, temperature sensing, etc., running along the skylight) and cold aisle maintenance, which also brings similar inconvenience to installation and maintenance personnel.

[0007] Therefore, it is of great significance to design a cold aisle installation frame structure that is both adaptable and easy to disassemble. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and provide a data center micro-module cold aisle structure with a maintenance window. This structure should have the characteristics of being structurally stable and easy to assemble and disassemble.

[0009] The technical solution of this utility model is:

[0010] A data center micro-module cold aisle structure with a maintenance window includes server racks on both sides of a cold aisle corridor and a skylight above the cold aisle corridor; the skylight is fixed to the server racks via raised windows on both sides; the raised window includes a frame connecting the server racks and the skylight and a maintenance window installed in the frame; the inner side of the maintenance window is flush with the inner side of the frame.

[0011] The frame includes horizontally arranged beams and several vertically arranged columns; the beams and columns are made of 4040 aluminum profiles.

[0012] The inspection window is a sheet metal part; the top and side edges of the inspection window are provided with L-shaped bends; the bottom edge of the inspection window is provided with Z-shaped bends that insert into the groove of the lower crossbeam; the two sides of the inspection window are provided with concealed handle buckles that insert into the grooves of the two side columns.

[0013] The L-shaped bend and Z-shaped bend are located on the side of the inspection window facing away from the cold aisle corridor; the height of the L-shaped bend is 10mm, and the height of the Z-shaped bend is 16-24mm.

[0014] The concealed handle latch includes a concealed box fixed to the inspection window, a pull block slidably positioned in the concealed box, a spring disposed between the concealed box and the pull block, and a pin connecting the pull block and capable of being pushed into the groove of the column; the handle groove of the pull block is disposed on the side of the inspection window facing the cold aisle corridor.

[0015] The latch is wedge-shaped, narrower at the front and wider at the back; the distance between the latch and the inspection window is greater than the height of the L-shaped bend.

[0016] The inspection window is equipped with tempered glass.

[0017] The skylights include functional skylights and resetting skylights arranged along the length of the cold aisle corridor.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a data center micro-module cold aisle structure with a maintenance window. The detachable maintenance window is installed on the aluminum profile of the frame, which not only strengthens the installation strength of the raised window and improves the light transmittance of the cold aisle corridor, but also allows the maintenance window to be installed and removed in the cold aisle corridor, facilitating line connection and cold aisle maintenance operations. This significantly improves the work convenience of installation and maintenance personnel, reduces the risk of deformation of the top of the rack, and enhances the overall maintainability and flexibility of the equipment. It is particularly suitable for cold aisle areas of data centers and server rooms. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0037] like Figure 1 As shown, a data center micro-module cold aisle structure with a maintenance window includes a cabinet 1, a skylight 2, and a raised window 3.

[0038] The server racks are arranged on both sides, with the cold aisle corridor A in the middle. The skylights are located above the cold aisle corridor, and the skylights and server racks are arranged in a triangular structure. End doors are set at the front and rear of the cold aisle corridor (omitted in the figure).

[0039] The skylight maintains a certain vertical distance from the top of the cabinet, and the skylight is fixed to the cabinet via the raised window 3. The skylight (existing technology) includes functional skylights and reset skylights arranged along the length of the cold aisle corridor, and the combination of functional skylights and reset skylights is set as needed.

[0040] The raised windows are installed on both sides of the cold aisle corridor and located between the server racks and the skylights, including a frame 4 and an inspection window 5. The frame is fixed to the top of the server rack and supports the skylight. The frame has multiple window frames arranged along the length of the cold aisle corridor, and an inspection window is installed in each window frame.

[0041] The frame includes horizontal beams 4-1 and vertical columns 4-2. The two horizontal beams are arranged horizontally, and multiple vertical columns are fixed between the upper and lower horizontal beams. The rectangular area enclosed by the beams and columns forms the window frame 4-3 for installing the inspection window. Figure 5 As shown, a total of 4 columns are set to form 3 window frames. The beams and columns are made of 4040 aluminum profiles with a cross-sectional dimension of 40×40mm, and each of the four sides of the aluminum profiles has an axially extending groove with a groove width of 8.5mm.

[0042] The inspection window is detachably installed in the window frame of the frame. The inspection window is a sheet metal part, and its four edges are all bent, including L-shaped bends 5-1 at the top edge and the two side edges and Z-shaped bends 5-2 at the bottom edge.

[0043] To improve the light transmittance of the inspection window and increase the brightness of the cold aisle corridor, a window 5-5 can be made in the middle of the inspection window, with tempered glass 7 fixed inside. Apply 3M double-sided tape (omitted in the diagram) to the edges of the window, then neatly align the tempered glass and place it on the 3M double-sided tape. Apply 3M double-sided tape to the pressing surface of the pressure plate 5-3 (the side facing the tempered glass), and use M4 nuts and screws to press the pressure plate and inspection window firmly into place, ensuring the tempered glass is tightly pressed into position. Be careful to maintain gaps between the 3M double-sided tape and the edges to prevent tape overflow.

[0044] To prevent cold air leakage inside the cold aisle corridor, sealing strips (omitted in the figure) need to be installed on the side of the L-shaped bend and Z-shaped bend facing the window frame to ensure a good seal.

[0045] To meet the requirements of sheet metal bending process and to match the installation width of sealing strip, the height h1 of L-shaped bend is 10mm, and the height h2 of Z-shaped bend is 16-24mm.

[0046] To ensure aesthetics, the inner side of the inspection window is flush with the inner side of the frame (the inner side facing the cold aisle corridor), and the inner side of the frame is flush with the inner side of the cabinet. The L-shaped bends and Z-shaped bends are located on the outer side of the inspection window (the side facing away from the cold aisle corridor). At the same time, the flat sealing strip 8 is inserted into the grooves of the crossbeam and the column located on the inner side of the inspection window.

[0047] To enable a detachable connection between the inspection window and the window frame, a Z-shaped bend is inserted downwards into the lower horizontal beam groove 4-1-1. Concealed handle clips 6 are installed on both sides of the inspection window. The pins of the concealed handle clips are inserted horizontally into the vertical column grooves 4-2-1 on both sides, so that the inspection window is completely fixed to the window frame.

[0048] The concealed handle latch includes a concealed box 6-1, a pull block 6-2, a spring, and a pin 6-3. The concealed box is fixed to the inspection window, which has a mounting hole 5-4. The concealed box is inserted into the mounting hole, and the edge of the mounting hole is embedded in the fixing slot 6-1-1 and the elastic slot 6-1-2 of the concealed box. The pull block with a handle groove 6-2-1 is slidably positioned in the concealed box. The spring is located between the concealed box and the pull block, and the pin is located outside the concealed box and connects to the pull block. This structure is the same as the existing concealed handle latch (DK725). Since the existing concealed handle latch utilizes the barb of the pin to engage with an external locking hole, and the aluminum profile used in this invention makes it difficult to manufacture locking holes for connecting the barb, this invention makes the following improvements to the concealed handle latch:

[0049] The handle groove of the pull block is located on the side of the inspection window facing the cold aisle corridor, and the latch is located on the side of the inspection window facing away from the cold aisle corridor. The latch is wedge-shaped, narrow at the front and wide at the back. The front end of the latch is an arc surface 6-3-1, which facilitates the alignment of the latch with the column groove. The width of the front end of the latch is less than the spacing between the grooves. There are inclined surfaces 6-3-2 on both sides of the latch to press against the column groove. The width of the rear end of the latch (9-11mm) is greater than the spacing between the column grooves. The latch will not be fully inserted into the column groove. The latch can hold against the columns on both sides. To avoid the L-shaped bend, the distance h3 between the bottom of the latch and the inspection window is greater than the height of the L-shaped bend.

[0050] The installation method for the inspection window is as follows: hook the two handle grooves with your fingers, causing the latches on both sides to retract inwards. Lift the inspection window and tilt it so that the Z-shaped bend downwards is inserted into the horizontal beam groove for initial positioning. Then, push the inspection window completely into the window frame, release your fingers, and the latches will pop out to both sides and push into the column grooves. The inspection window will then be fully locked into the window frame, and the installation is complete. The window frame can be removed by reversing the operation.

[0051] This innovative design integrates a detachable inspection window, allowing technicians quick access to internal equipment for routine inspections, troubleshooting, or component replacement, while maintaining the airtightness of the cold aisle corridor to ensure uninterrupted cooling. This design not only improves system reliability and maintenance efficiency but also meets the energy-saving and operability requirements of high-density data centers.

[0052] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
