[0027] 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.

[0028] Example 1

[0029] Please see Figures 1-6 The present invention provides the following technical solution:

[0030] A data center computer room cooling aisle device, comprising:

[0031] Refrigeration fan 1;

[0032] Dust filter fixing plate 2 is fixedly connected to the lower end of the refrigeration fan 1;

[0033] The dustproof assembly consists of two sets. Each set includes an installation slide 3, a fixed insertion slot 4, an installation filter plate 5, a fixed insert block 6, a spring push plate 7, a fixed spring 8, and a fixed insert block 9. The installation slide 3 is located at the lower end of the dust filter fixing plate 2. The fixed insertion slot 4 is located on one side of the inner wall of the installation slide 3. The installation filter plate 5 is slidably connected to the dust filter fixing plate 2. The fixed insert block 6 is fixedly connected to one side of the installation filter plate 5. The spring push plate 7 is slidably connected to the fixed insert block 6. The fixed spring 8 is fixedly connected to one side of the inner wall of the fixed insert block 6 and one side of the spring push plate 7. The fixed insert block 9 is fixedly connected to one side of the spring push plate 7 and slides within the fixed insertion slot 4. The upper end of the fixed insert block 9 is an inclined surface.

[0034] In a specific embodiment of this utility model, the dust filter fixing plate 2 is fixedly connected to the lower end of the refrigeration fan 1 to support and guide the cold air into the machine room. The device also includes two sets of dustproof components, which are respectively arranged on both sides of the dust filter fixing plate 2 to achieve efficient filtration of the cold air. The filter plate 5 is installed in the mounting groove 3 by sliding, which is convenient for disassembly, cleaning or replacement. A fixing block 6 is fixedly connected to one side of the filter plate 5. The fixing block 6 has a slidingly connected spring push plate 7 inside. A fixing spring 8 is arranged between the inner wall of one side of the fixing block 6 and the spring push plate 7 to provide a restoring force for the spring push plate 7. One side of the spring push plate 7 is fixed. The connecting fixed insertion block 9 can slide within the fixed insertion groove 4, and its upper end is designed as an inclined surface to automatically guide and lock into the fixed insertion groove 4 during insertion, thereby achieving quick locking of the filter plate 5. When it is necessary to replace or clean the filter plate 5, the fixed insertion block 9 can be disengaged from the fixed insertion groove 4 by manually pushing the spring push plate 7 to compress the fixed spring 8, so that the filter plate 5 can be slid out of the installation slide 3 for maintenance. During the maintenance process, since the dustproof component on the other side is still in working condition, it can ensure a continuous supply of cold air and prevent dust from entering the machine room, thus ensuring a clean and stable operating environment for the equipment.

[0035] Please refer to the details. Figures 1-6 The lower inner wall of the fixed insert 6 is provided with a disassembly groove 10, and the lower end of the spring push plate 7 is fixedly connected with a disassembly pull plate 11, which slides in the disassembly groove 10.

[0036] In this embodiment: when the filter plate 5 needs to be replaced or cleaned, the disassembly plate 11 is pulled outward, causing the spring push plate 7 to move synchronously and compressing the fixing spring 8, so that the fixing insertion block 9 disengages from the fixing insertion groove 4. At this time, the filter plate 5 can be slid out along the mounting slide groove 3, achieving quick disassembly. During the disassembly process, this structure effectively reduces the difficulty of operation, improves maintenance efficiency, and ensures smooth and reliable operation.

[0037] Please refer to the details. Figures 1-6 The filter plate 5 is equipped with a dust filter pad 22. The upper end of the dust filter pad 22 is provided with an air inlet 12. The lower inner wall of the air inlet 12 is provided with a loop dust filter hopper 13. The lower end of the loop dust filter hopper 13 is provided with an air outlet 14.

[0038] In this embodiment: the upper end of the dust filter pad 22 is provided with an air inlet 12, which serves as the first channel for cold air to enter the dust filter structure. The lower inner wall of the air inlet 12 is provided with a loop dust filter hopper 13. The loop dust filter hopper 13 adopts a tortuous structure design, which extends the airflow path when passing through, thereby improving the settling and filtration efficiency of dust particles and enhancing the overall dust removal effect. The lower end of the loop dust filter hopper 13 is provided with an air outlet 14, through which the cold air after multi-stage filtration is discharged and continues to be transported to the cold aisle, and finally sent into the server rack area to achieve a stable and clean cooling cycle.

[0039] Please refer to the details. Figures 1-6 Two air vents 21 are provided at the upper end of the dust filter fixing plate 2, and the two sets of dustproof components are respectively provided in the two air vents 21.

[0040] In this embodiment: when a set of dustproof components is disassembled and replaced, the corresponding air vent 21 can be covered by another set of dustproof components and continue to provide clean airflow, while preventing unfiltered air from directly entering the cold aisle, ensuring the cleanliness of the computer room environment. This structure not only improves the redundancy and continuous operation capability of the system, but also enhances the safety and practicality of the equipment during daily maintenance.

[0041] Please refer to the details. Figures 1-6 Each air vent 21 is equipped with an air vent assembly. Each air vent assembly includes a misaligned slide groove 15, a fixed air vent plate 16, a movable air vent plate 17, an air vent sealing spring 18, and a pressure block 19. The misaligned slide groove 15 is located on one side inner wall of the air vent 21. The movable air vent plate 17 is slidably connected in the misaligned slide groove 15. The fixed air vent plate 16 is fixedly connected to the side inner wall of the air vent 21. The fixed air vent plate 16 matches the movable air vent plate 17 to seal the upper opening of the air vent 21. The air vent sealing spring 18 is fixedly connected to the upper inner wall of the misaligned slide groove 15 and the upper end of the movable air vent plate 17. The pressure block 19 is fixedly connected to the lower end of the movable air vent plate 17. When the dustproof assembly is installed, the pressure block 19 contacts the filter plate 5 and squeezes the fixed air vent plate 16 and the movable air vent plate 17 to become misaligned.

[0042] In this embodiment: the misaligned groove 15 is formed on one inner wall of the wind deflector 21 to guide and restrict the sliding trajectory of the movable wind deflector 17, enabling it to move stably in a set direction. The movable wind deflector 17 is slidably connected within the misaligned groove 15 and is matched with the fixed wind deflector 16 fixedly connected to the inner wall of the wind deflector 21. The two work together to completely seal the upper opening of the wind deflector 21, preventing cold air leakage or external dust from entering. One end of the air vent sealing spring 18 is fixedly connected to the upper inner wall of the misaligned groove 15, and the other end is connected to the upper end of the movable wind deflector 17, providing upward reset for the movable wind deflector 17. The elastic force allows the air vent sealing spring 18 to push the movable baffle 17 upward when the dustproof component is not installed or is removed, so that it fits tightly against the fixed baffle 16, thereby effectively sealing the air vent 21. The lower end of the movable baffle 17 is fixedly connected to a pressure block 19, which contacts the filter plate 5 during the installation of the dustproof component and is subjected to pressure from the filter plate 5, thereby pushing the movable baffle 17 downward to compress the air vent sealing spring 18, causing the movable baffle 17 and the fixed baffle 16 to be relatively misaligned, thereby opening the air vent 21 and allowing the filtered cold air to pass through.

[0043] Please refer to the details. Figures 1-6 The lower end of the refrigeration fan 1 is provided with a cold air outlet 20, and the dust filter fixing plate 2 is fixedly connected to the output end of the cold air outlet 20.

[0044] In this embodiment: After the cold air is output from the internal cold air vent 1 through the cold air outlet 20, it first enters the dustproof component supported by the dust filter fixing plate 2. After being filtered by the dust filter cotton pad 22 in the filter plate 5, the dust and impurities in the air are removed. Then, it passes through the air inlet 12, the loop dust filter hopper 13 and the air outlet 14 in sequence into the baffle 21, and is finally sent into the cold aisle for cooling the server equipment.

[0045] The working principle and usage process of this utility model: The dust filter fixing plate 2 is fixedly connected to the lower end of the refrigeration fan 1 to support and guide the cold air into the machine room. The device also includes two sets of dustproof components, which are respectively set on both sides of the dust filter fixing plate 2 to achieve efficient filtration of the cold air. The filter plate 5 is installed in the mounting groove 3 by sliding, which is convenient for disassembly, cleaning or replacement. A fixing block 6 is fixedly connected to one side of the filter plate 5. The fixing block 6 has a slidingly connected spring push plate 7 inside. A fixing spring 8 is set between the inner wall of one side of the fixing block 6 and the spring push plate 7 to provide a restoring force for the spring push plate 7. The spring push plate 7 is fixed to one side of the filter plate 5. A fixed insertion block 9 is connected and can slide within the fixed insertion slot 4. Its upper end is designed as an inclined surface to automatically guide and lock into the fixed insertion slot 4 during insertion, thereby achieving quick locking of the filter plate 5. When it is necessary to replace or clean the filter plate 5, the fixed insertion block 9 is disengaged from the fixed insertion slot 4 by manually pushing the spring push plate 7 to compress the fixed spring 8. The filter plate 5 can then be slid out of the installation slide 3 for maintenance. During maintenance, since the dustproof component on the other side is still in working condition, it can ensure a continuous supply of cold air and prevent dust from entering the machine room, thus ensuring a clean and stable operating environment for the equipment.

[0046] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
