[0030] The embodiment of the utility model provides a cabinet door, including: a mesh door 2 and a door curtain 1, the door curtain 1 is arranged parallel to the mesh door 2 and fixed to the mesh door 2; the door curtain 1 includes a plurality of door curtain pages 12, and some and / or all of the door curtain pages 12 can be opened and / or closed; when the door curtain pages 12 are closed, there is no gap between adjacent door curtain pages 12, and adjacent door curtain pages 12 are connected by a sealing connection part 13, and the sealing connection part 13 is used to connect and seal adjacent door curtain pages 12 to prevent external airflow from reaching the mesh door through the gap between adjacent door curtain pages 12; when the door curtain page 12 is opened, external airflow can pass through the mesh door 2. The cabinet door provided by the embodiment of the utility model solves the technical defect in the prior art that the ventilation volume of the cabinet door of the computer room cannot be adjusted, which further leads to poor cooling effect of the computer room.

[0031] See here Figure 1 , Figure 1 The left and right sides are schematic diagrams of the structure of the door curtain 1 being closed and opened respectively. In the technical solution provided by the embodiment of the utility model, the ventilation volume entering the mesh door 2 through the door curtain 1 can be adjusted by opening / closing part / all of the door curtain pages 12.

[0032] See also here for further information Figure 4 , Figure 4 The schematic diagram of the structure of the door curtain 1 after all the door curtain pages 12 are opened, at this time, the door curtain pages 12 are all opened, the door curtain pages 12 are overlapped, and the total width of the door curtain 1 is the width of a single door curtain page 12. At this time, the ventilation volume entering the mesh door 2 through the door curtain 1 reaches the maximum; when all the door curtain pages 12 are closed, there is no gap between adjacent door curtain pages 12, and the external cold air flow cannot pass through the door curtain pages 12 to reach and pass through the mesh door 2 due to the obstruction of the door curtain pages 12. At this time, the ventilation volume of the mesh door 2 is zero. Therefore, by adjusting the number of door curtain pages 12 opened, the ventilation volume entering the meshes through the door curtain 1 is adjusted.

[0033] Therefore, when the air reaching and passing through the door curtain 1 and the mesh door 2 is cold air, the door curtain leaves 12 can be opened and / or closed according to actual cooling needs, and the opening width of the door curtain 1 can be adjusted to adjust the ventilation volume of cold air entering the mesh door 2 through the door curtain 11, thereby effectively avoiding waste of cold air.

[0034] The sealing connection portion 13 can ensure good connection and sealing effect between adjacent door curtain pages 12, and effectively prevent the external cold air flow from passing through the gaps between the door curtain pages 12 and entering the mesh door 2 when the door curtain 1 is closed, causing waste of cold energy.

[0035] See here Figure 2The sealing connection part 13 includes: a first connection hook and a second connection hook, the first connection hook and the second connection hook are arranged opposite to each other, and the first connection hook and the second connection hook can be hooked together. The first connection hook and the second connection hook cooperate with each other to complete the sealing of adjacent door curtain pages 12, which is more convenient in use and has the advantages of simple structure and not easy to be damaged.

[0036] See here for further information Figure 3 In the technical solution provided by the embodiment of the utility model, the door curtain 1 also includes: a guide rail 11, and the end of the door curtain page 12 is slidably arranged in the guide rail 11. On the one hand, the guide rail 11 can provide a direction guide for the opening / closing of the door curtain page 12, ensuring that the door curtain page 12 can move in a preset direction when adjusting the position, further optimizing the stability of the position of the door curtain 1; at the same time, the guide rail 11 can also provide a certain support effect for the door curtain page 12, making the overall structure of the door curtain 1 more stable.

[0037] The technical solution is further optimized to further enhance the sealing effect of the sealing connection 13, especially when the height of the door curtain leaf 12 is high, to effectively ensure that the external cold air flow cannot enter the cabinet door. In a cabinet door provided by an embodiment of the utility model, the number of sealing connections 13 is greater than two, and the sealing connections 13 are arranged at longitudinal intervals.

[0038] To further optimize the technical solution, in the technical solution provided by the embodiment of the utility model, in one embodiment, the number of guide rails 11 is two groups, namely: a first guide rail and a second guide rail, the upper part of the door curtain page 12 is slidably arranged in the first guide rail, and the lower part of the door curtain page 12 is slidably arranged in the second guide rail. The first guide rail and the second guide rail arranged up and down can further effectively improve the directional guidance and support effect of the guide rail 11, so that the door curtain 1 can be more stable in the open / closed state, and the position is more accurate.

[0039] In order to further expand the application scenarios of the cabinet door, in a cabinet door provided by the embodiment of the utility model, a set of guide rails 11 is composed of two left and right sections of guide rails 11, and the length of the two sets of guide rails 11 sections after being horizontally connected is greater than the width of the mesh door 2. The structural design of the left and right sections can make the door curtain 1 adapt to different types of application scenarios, and can further reduce the size of the guide rails 11, which is convenient for the installation of the guide rails 11.

[0040] In a cabinet door provided by an embodiment of the utility model, a heat insulation layer is provided on the surface of the door curtain 12. After the heat insulation layer structure is provided, the heat insulation performance of the door curtain 1 will be further enhanced, especially when the door curtain 12 is closed, the cold air consumption through the door curtain 11 can be ignored.

[0041] To further optimize the technical solution, in order to minimize the impact on the refrigeration effect when high-speed refrigeration is required after the door curtain 1 is installed, in the technical solution provided by the embodiment of the utility model, the width of a single door curtain leaf 12 is smaller than the width of the unopened mesh at the edge of the mesh door 2. Figure 4 , Figure 4 When the door curtain 1 is fully opened, the width of the door curtain 1 (i.e., a single door curtain leaf 11) is a; Figure 1 , Figure 1 The width of the unopened hole at the edge of the middle mesh door is b. When the door curtain 12 is fully opened, if a≤b, the outside cold air can reach and pass through the mesh door 2 with the highest efficiency, and the existence of the door curtain 1 does not have any obstructive effect on the cooling effect.

[0042] In a cabinet door provided by an embodiment of the utility model, the mesh door 2 and the door curtain 1 are detachably connected. When there is no need to adjust the cooling effect, the door curtain 1 can be removed and installed in other areas where it is needed, so as to avoid the door curtain 1 being idle.

[0043] It can be concluded from the above specific embodiments that the cabinet door provided by the utility model has the following advantages:

[0044] (1) For idle cabinets, they can be completely closed to avoid "ineffective circulation" and waste of cooling capacity;

[0045] (2) For installed cabinets, the degree of enclosure can be adjusted according to the number of IT devices in a single cabinet and the power consumption, thereby adjusting the air supply volume of the entire cold channel to avoid excessive waste of cold sources;

[0046] (3) The cold channel is truly “closed”, which enables efficient air conditioning and refrigeration, thus truly solving the problem of local overheating of some high-power consumption equipment;

[0047] (4) It can realize the ability to meet the requirements of flexible cabinets, that is, flexible cabinets increase the power upper limit of a single cabinet while keeping the power threshold of the entire row unchanged, making server rack installation more flexible, thereby reducing power loss during the installation process and improving the utilization rate of rack installation resources; for example, the average power of the cabinet is 10KW, but the power of the cabinets in the row can fluctuate around 10KW, and the actual power used by the entire row does not exceed the average power of the cabinet 10KW, thereby improving the utilization rate of rack installation;

[0048] (5) The PUE (Power Usage Effectiveness) value of the entire computer room is reduced, meeting the requirements of "energy saving and emission reduction" and "green and low-carbon".
