Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a filter and a computer room air conditioner. Background Technology

[0002] Data center air conditioning is an air conditioning device specifically designed for data center environments. It features high precision, high reliability, energy saving, and environmental protection. It is used to maintain parameters such as temperature, humidity, cleanliness, and airflow distribution in the data center, ensuring the normal operation of equipment and extending its service life. It is widely applicable to high-precision environments such as computer rooms, program-controlled exchange rooms, satellite mobile communication stations, large medical equipment rooms, laboratories, testing rooms, and precision electronic instrument production workshops.

[0003] Current computer room air conditioner filters generally use diamond-shaped filters. The unique design of the diamond-shaped filter, with its mesh spacing arranged in a diamond pattern, results in a larger filtration area than ordinary filters. This allows it to process more water flow in the same amount of time, leading to higher filtration efficiency and effectively filtering out fine particulate matter with very high filtration precision. However, because computer room air conditioner filters are typically large, to prevent deformation, bending, and detachment during transportation and use, current filters generally employ a splicing design, dividing the filter into several pieces. However, due to current technological limitations, the connection strength of this splicing design is relatively low, and problems such as deformation, bending, and detachment still occur, resulting in relatively low filter reliability. Utility Model Content

[0004] The purpose of this utility model is to provide a filter and a computer room air conditioner. The filter sheet inside the outer frame is divided into grids by using multiple reinforcing ribs, which improves the overall strength of the filter, enhances its resistance to deformation, reduces the risk of bending deformation, and solves the technical problem of low reliability of existing filters.

[0005] To achieve the above objectives, this utility model provides a filter screen, including an outer frame and a plurality of filter screen pieces. The outer frame is fixedly provided with reinforcing ribs to divide the frame opening of the outer frame into at least two sub-frame openings, and each filter screen piece is embedded in each sub-frame opening. The inner sidewall of the sub-frame opening is provided with a snap-fit ​​groove, and the edge of the filter screen piece is respectively inserted into the corresponding snap-fit ​​groove.

[0006] Preferably, it also includes a mesh screen that covers all the filter screens, and the mesh screen has a smaller aperture than the filter screens.

[0007] Preferably, the outer frame includes four frame strips connected end to end in sequence, and angle iron is provided at the connection of any two adjacent frame strips; reinforcing ribs are intersecting and arranged inside the outer frame.

[0008] Preferably, the angle iron and the frame strip are connected by rivets, and any two adjacent reinforcing ribs are connected by rivets.

[0009] Preferably, the side of the frame strip away from the snap-fit ​​groove and the side of the reinforcing rib away from the snap-fit ​​groove are both provided with receiving grooves, and the angle iron and rivets are located in the receiving grooves.

[0010] Preferably, the cross-section of the snap-fit ​​groove is C-shaped.

[0011] Preferably, any reinforcing rib is fixed with a handle.

[0012] Preferably, the reinforcing rib has a recessed groove, and the handle is located in the recessed groove.

[0013] Preferably, the cross-section of the filter screen is wavy, and the wire diameter of the filter screen is greater than or equal to 0.5 mm.

[0014] This utility model provides a computer room air conditioner, including the above-mentioned filter.

[0015] Compared to the prior art, this invention optimizes the structure of the filter screen by fixing several reinforcing ribs inside the outer frame. All the reinforcing ribs divide the frame opening of the outer frame into at least two sub-frame openings, and each filter screen is embedded in its respective sub-frame opening. This invention uses the reinforcing ribs to divide the frame opening of the outer frame into a grid, enabling the filter screen to achieve a grid design. Compared to the existing filter screens that are set as a single piece, the grid design makes each reinforcing rib a supporting skeleton for the filter screen, providing sufficient support for each filter screen and enabling each filter screen to withstand stronger load impacts, thereby improving the mechanical strength of each filter screen. Moreover, in addition to supporting the filter screens, each reinforcing rib provides stable support for the frame opening of the outer frame, improving the deformation resistance and mechanical connection strength of the outer frame, reducing the risk of bending deformation of the outer frame, and improving reliability.

[0016] In addition, the inner wall of the sub-frame opening is provided with a snap-fit ​​groove. The edges of the filter screen are respectively inserted into the corresponding snap-fit ​​grooves, so that the filter screen is fully opened by the sub-frame opening and the filter screen is restricted from falling out of the sub-frame opening. This ensures that the filter screen is reliably fixed in the sub-frame opening, improves the connection strength between the filter screen and the sub-frame opening, and avoids problems such as shrinkage or falling off of the filter screen due to load impact, thus further improving reliability.

[0026] 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.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] This utility model discloses a filter screen, as shown in the attached figure. Figure 1 As shown, the device includes an outer frame 1 and multiple filter sheets 3. Several reinforcing ribs 2 are fixed inside the outer frame 1 to divide the frame opening of the outer frame 1 into at least two sub-frame openings, with each filter sheet 3 embedded in its respective sub-frame opening. The reinforcing ribs 2 are used to create a grid-like division of the frame opening of the outer frame 3, enabling the filter sheets 3 to achieve a grid-like design. Compared to existing single-piece filter sheets, the grid-like design makes each reinforcing rib 2 a supporting skeleton for the filter sheets 3, providing sufficient support for each filter sheet 3 and enabling it to withstand stronger load impacts, thereby improving the mechanical strength of each filter sheet 3. Furthermore, in addition to supporting the filter sheets 3, each reinforcing rib 2 provides stable support for the frame opening of the outer frame 1, improving the deformation resistance and mechanical connection strength of the outer frame 1, reducing the risk of bending deformation of the outer frame 1, and improving reliability.

[0029] The inner wall of the sub-frame opening is provided with a snap-fit ​​groove 4. The edge of the filter screen 3 is inserted into the corresponding snap-fit ​​groove 4, so that the filter screen is fully opened by the sub-frame opening and the filter screen is restricted from leaving the sub-frame opening. This ensures that the filter screen is reliably fixed in the sub-frame opening, improves the connection strength between the filter screen and the sub-frame opening, and avoids problems such as shrinkage or falling off of the filter screen due to load impact, thus further improving reliability.

[0030] This utility model uses multiple reinforcing ribs 2 to divide the filter mesh 3 inside the outer frame 1 into a grid, which improves the overall strength of the filter mesh, enhances its resistance to deformation, reduces the risk of bending deformation, and improves its reliability.

[0031] Please refer to the above as well. Figures 1 to 6 In a preferred embodiment, the outer frame 1 is a rectangular frame with a rectangular opening at its center. The outer frame 1 includes four frame strips 11 connected end to end in sequence. Specifically, each frame strip 11 includes two parallel horizontal frame strips and two parallel vertical frame strips, with the horizontal and vertical frame strips connected perpendicularly to each other. Three reinforcing ribs 2 are provided inside the opening of the outer frame 1, including one vertical reinforcing rib perpendicularly connected between two horizontal frame strips and two parallel horizontal reinforcing ribs perpendicularly connected between two vertical frame strips. The three reinforcing ribs 2 divide the opening of the outer frame 1 into six sub-openings, each sub-opening being square, and each filter element 3 correspondingly being square. To ensure that each filter element 3 is subjected to uniform force, the two ends of the vertical reinforcing rib are fixedly connected to the center of the two horizontal frame strips, and the two horizontal reinforcing ribs and the two horizontal frame strips are evenly spaced. It is important to note that the vertical and horizontal reinforcing ribs are connected at an intersection. One of the vertical and horizontal reinforcing ribs has a clearance groove in its center, which mates with the other to ensure that the vertical and horizontal reinforcing ribs are on the same plane. Specifically, each vertical and horizontal reinforcing rib has the same structure, consisting of two aluminum alloy profiles joined together. Adjacent sides of the two aluminum alloy profiles have receiving grooves, allowing the rivets connecting the two profiles to be recessed within these grooves. Opposite sides of the two aluminum alloy profiles each have snap-fit ​​grooves for embedding the filter screen 3. Of course, the structure of the reinforcing rib 2 is not limited to this.

[0032] The filter also includes a mesh screen, which covers all the filter screen pieces 3. The mesh screen has a smaller aperture than the filter screen pieces 3 to prevent larger impurities such as willow catkins from clogging the filter screen pieces 3, reducing the maintenance frequency and cost of the filter screen pieces 3. As a preferred embodiment, the mesh screen can also be divided into several mesh screen pieces, with each filter screen piece 3 covered by one mesh screen piece. Each mesh screen piece is fixed to the filter screen piece 3 by adhesive bonding, or the edge of the mesh screen piece is pressed into the gap between the snap-fit ​​groove and the filter screen piece 3. Of course, the structure of the mesh screen is not limited to this; for example, a single piece of mesh screen can cover all the filter screen pieces 3 to achieve the filtration purpose. This reduces the difficulty of mesh screen installation. The specific structure of the mesh screen can be flexibly selected according to the working scenario of the filter.

[0033] To enhance the mechanical strength of the outer frame 1, angle irons 12 are provided at the joints of any two adjacent frame strips 11 to ensure a reliable connection between them. The angle iron 12 is L-shaped and fixedly connected to the two frame strips 11 at its two ends. The angle iron 12 includes a horizontal connecting piece fixedly connected to the horizontal frame strip and a vertical connecting piece fixedly connected to the vertical frame strip; the horizontal and vertical connecting pieces are integrally and vertically connected. It should be noted that the length and thickness of the horizontal and vertical connecting pieces are adjusted according to the specifications of the outer frame 1 and are not specifically limited here.

[0034] The cross-section of the snap-fit ​​groove can be roughly C-shaped; therefore, C-shape includes C-shape, U-shape, V-shape, H-shape, and similar shapes. Both the frame strip 11 and the reinforcing rib 2 can be integrally formed aluminum alloy profiles, making the entire filter lighter and more easily meeting lightweight design requirements.

[0035] Angle iron 12 is riveted to frame strip 11 by rivets 13, ensuring reliable connection between adjacent frame strips 11 and improving the mechanical strength of outer frame 1. Adjacent reinforcing ribs 2 are also riveted to each other by rivets 13, ensuring reliable connection between adjacent reinforcing ribs 2, so that reinforcing ribs 2 can both firmly fix the filter screen 3 and provide reliable support for outer frame 1. Of course, it is not limited to rivet connections.

[0036] The side of the frame strip 11 away from the snap-fit ​​groove 4 and the side of the reinforcing rib 2 away from the snap-fit ​​groove 4 are both provided with receiving grooves 5. Angle iron 12 and rivets 13 are all located in the receiving grooves 5 to avoid gaps caused by interference between the sides of the outer frame 1 or between two adjacent reinforcing ribs 2, ensuring that the overall structure of the filter screen is compact. The receiving grooves 5 and snap-fit ​​grooves 4 are respectively provided on two opposite sides of the reinforcing rib 2. The depth of the snap-fit ​​groove 4 is greater than the depth of the receiving groove 5, so that the snap-fit ​​groove 4 can both secure the filter screen 3 and ensure that the material consumption of the reinforcing rib 2 is minimized, which helps to reduce costs.

[0037] A handle 21 is fixed to any reinforcing rib 2 for easy lifting of the filter screen. In a preferred embodiment, the handle 21 is specifically fixed to the reinforcing rib 2 located at the center of the outer frame 1 by screw connection to ensure that the filter screen is evenly stressed. The handle 21 adopts a recessed design, with the reinforcing rib 2 having a recessed groove, and the handle 21 is located in the recessed groove to avoid the handle 21 being too high and causing interference.

[0038] Each filter screen 3 has a square structure and measures 500*500mm, although the specifications are not limited to this. The cross-section of the filter screen 3 is wavy to ensure sufficient strength. The filter screen 3 is preferably made of galvanized or stainless steel mesh to improve its corrosion resistance. The wire diameter of the filter screen 3 is greater than or equal to 0.5mm; increasing the wire diameter further enhances the strength of the filter.

[0039] This utility model embodiment also provides a computer room air conditioner, including the above-mentioned filter screen. The filter screen is installed inside the outdoor unit of the computer room air conditioner and is used to filter outdoor air. The filter screen has high strength, low failure rate, and the overall reliability of the unit is also improved.

[0040] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0041] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
