[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0038] The core of the present invention is to provide a filter structure that can ensure the reliable fixation of the filter, ensure the structural strength of the filter structure as a whole, and improve the efficiency of installation and maintenance. Another core of the present invention is to provide a cooling unit including the filter structure.
[0039] The filter structure provided by the present invention includes a filter 11 and a filter frame 12. Please refer to Figure 1 .
[0040] Each filter frame 12 has a hollow area. Specifically, the filter frame 12 can be a square structure, a circular structure, a polygonal structure, an irregular structure, etc., and can be set according to the occasion to which the filter structure is to be used and the installation scenario of the filter structure.
[0041] For example, the filter frame 12 is set to be square and the hollow area is also set to be square, so that the square filter 11 can be installed and fixed on the filter frame 12, and the square filter frame 12 is fixed on the overall frame of the filter component.
[0042] For example, the filter frame 12 is set to be square and the hollow area is set to be circular, so that the circular filter 11 can be installed and fixed on the filter frame 12, and the square filter frame 12 can be fixed on the overall frame of the filter component.
[0043] The edge of the filter frame 12 is provided with a dead edge structure, and the filter 11 is provided in the hollow area of the filter frame 12. The edge of the filter 11 is connected to the corresponding dead edge structure.
[0044] The specific processing of the dead edge structure is as follows: the first method is to bend the edge of the plate with a bending knife, and then flatten the bent part on the plane of the plate to form a dead edge structure by one dead edge pressing; the second method is to bend the plate at a certain angle with a bending knife to form a bent edge, and then put a pad between the plate plane and the bent edge, flatten the bent edge, and pull out the pad to form a dead edge structure by bending 180 degrees; the third method is to press the dead edge by triple folding, which specifically refers to the process of pressing the dead edge after bending three times, which can also form a dead edge structure. The plate in the above process specifically refers to the plate used to process the filter frame 12.
[0045] In a specific embodiment, when the dead edge structure and the filter 11 are connected, the filter 11 can be first placed in the bent part of the filter frame 12, and then the bent part can be directly pressed through a pressing mold to press the filter 11 directly into the dead edge structure, thereby ensuring that the filter 11 is reliably and effectively fixed, reducing the possibility of the filter 11 falling off from the filter frame 12, and ensuring the overall strength and reliability of the filter structure, so as to facilitate the installation and disassembly of the filter structure.
[0046] The edge of the filter frame 12 is provided with a dead edge structure. There are many specific implementations of providing the dead edge structure on the edge of the filter frame 12, such as providing the dead edge structure on all or part of a certain edge of the filter frame 12.
[0047] In a specific embodiment, the filter frame 12 is a square structure with a hollow area, and each edge of the square structure has a dead edge structure, and the edge of the filter 11 is pressed against the dead edge structure by the dead edge structure, ensuring the reliable fixation of the filter 11 and the strength and reliability of the filter structure as a whole. In another specific embodiment, the edges of the filter frame 12 are respectively provided with a wavy structure, and the multiple waves included in the wavy structure can be partially provided with a dead edge structure, such as the wave structures at the two end positions are provided with dead edges, and the waves at other positions remain flush with the plane of the filter frame 12. Part of the edge of the filter 11 is fixed by the dead edge structure at the end, and the position of the dead edge structure corresponds to the end position of the filter 11 in the circumferential direction.
[0048] In addition, the filter frame 12 is a sheet metal part. The light weight and high strength of the sheet metal part are used to ensure the reliability of the filter frame 12. The specific sheet metal part can be stainless steel, alloy structural steel, carbon steel, etc., and can be flexibly selected based on the actual usage scenario.
[0049] On the basis of setting the filter frame 12 as a sheet metal part, since the dead edge structure can clamp and fix the filter 11 in the gap of the dead edge structure, the fixing strength of the filter 11 can be improved. Therefore, the dead edge structure of the filter frame 12 also has good structural strength, ensuring the reliable fixation of the edge of the filter 11, ensuring the structural strength of the filter structure as a whole, improving the service life of the filter structure, and improving the efficiency of installation and maintenance. When the filter structure is used in a specific way, such as when it is applied to a cooling unit or other settings that require filtering, it is convenient to install and disassemble the components. Based on the good service life of the filter structure, even if it is affected by the vibration of the unit or is pulled quickly, the components are not easily damaged, thereby improving the efficiency of installation and maintenance.
[0050] Based on the above embodiment, the number of filter frames 12 is at least two, and any two adjacent filter frames 12 are rotatably connected. The edge of each filter frame 12 is provided with a dead edge structure, and the hollow area of each filter frame 12 is provided with a filter 11. The edge of the filter 11 is connected to the corresponding dead edge structure, which improves the fixing strength of the filter 11, ensures the stable and reliable installation of each filter 11 relative to the filter frame 12, and guarantees the service life of the filter structure.
[0051] Any two adjacent filter frames 12 are rotatably connected, and the rotatable connection can be achieved through a rotating shaft. Through the rotatable connection between at least two filter frames 12, the filter structure can be relatively rotated to facilitate disassembly or transportation and transfer; the filter 11 is arranged in the hollow area of the filter frame 12, and the filter structure can be folded or unfolded by rotating the filter frame 12, that is, the filter 11 is folded or unfolded.
[0052] In a specific embodiment, when at least two filters 11 and the filter frame 12 are removed as a whole from the mounting frame of the component to be filtered, the rotating connection method can make the filter structure more flexible, so that the filter frame 12 can be rotated appropriately according to the actual disassembly situation, so that the filter structure as a whole is in a folded or unfolded state, thereby improving the disassembly efficiency and enhancing the structural strength.
[0053] In another specific embodiment, when at least two filters 11 and a filter frame 12 are installed as a whole on the mounting frame of the component, the filter structure as a whole can first be entered in a retracted state. Under the rotational connection mode, the filter structure has greater flexibility. After loosening, the filter structure can be quickly unfolded from the retracted state, thereby improving the installation efficiency and enhancing the structural strength.
[0054] On the premise that the strength of the filter frame 12 is high, the overall size of the filter 11 can be set larger, thereby improving the integrity of the filter structure and facilitating the connection between the overall filter structure components and the component installation frame.
[0055] The mounting frame of the components in the above process specifically refers to the location where the filter structure is to be installed. For example, when applied to a cooling unit, the mounting frame is the frame of the entire unit.
[0056] The setting of at least two rotatably connected filter frames 12 can improve the efficiency of installing and disassembling the filter structure. The setting of a dead edge structure on the edge of the filter frame 12 can improve the overall strength and reliability of the filter structure, so that the filter structure has better flexibility and effectively improves the service life of the filter structure.
[0057] Based on any of the above embodiments, the dead edge structure includes a folded edge, which is pressed onto the edge of the corresponding filter frame 12 , and the edge of each filter 11 is pressed between the corresponding folded edge and the edge of the corresponding filter frame 12 .
[0058] In this embodiment, the dead edge structure can specifically satisfy the effect of pressing the filter 11 onto the edge of the filter frame 12 by folding the edge, and does not limit the specific number of bending times and the specific bending angle of the folded edge.
[0059] By pressing the edge of the filter 11 between the folded edge of the corresponding dead edge structure and the edge of the corresponding filter frame 12, the filter 11 is ensured not to fall off easily, thereby ensuring the service life and structural strength of the entire filter structure and facilitating disassembly and maintenance operations.
[0060] Based on any of the above embodiments, please refer to Figure 1 、 Figure 5 Any two adjacent filter frames 12 are rotatably connected via a hinge axis, and the filter frames 12 can rotate around the hinge axis to be in an expanded state or a folded state. At least two filter frames 12 are rotatably connected, and the filter screens 11 connected by the dead edge structures corresponding to at least two filter frames 12 can rotate relative to each other, that is, the filter screens 11 corresponding to any two adjacent filter frames 12 can be relatively expanded or relatively folded, that is, the filter screen structure can have an expanded state and a folded state, so as to facilitate flexible assembly and disassembly operations. For example, in a smaller working space, the filter screen structure can be quickly disassembled and maintained by switching between the expanded state and the folded state, thereby improving the efficiency of installation and disassembly and reducing the risk of damage to the filter screen structure.
[0061] Taking a specific implementation as an example, if two filter screens 11 are set, a cylindrical structure can be set on the side of the filter frame 12 corresponding to the two filter screens 11 to facilitate the placement of the hinge shaft. This cylindrical structure can be bent to form a curling edge at the part of the side of the filter frame 12 where no dead edge is set, that is, the dead edge structure and the curling edge structure are formed on a piece of plate at the same time, and the curling edges formed by bending the two filter frames 12 are coaxially connected through the hinge shaft to achieve the effect that the filter structure can have an expanded state and a folded state.
[0062] Taking a specific implementation as an example, if two filters 11 are set, the filter frames 12 corresponding to the two filters 11 are connected by a hinge, the edge of the filter 11 is fixed to the dead edge structure of the filter frame 12, and the hinge is provided on the two adjacent filter frames 12 so that the hinge can rotate without interference, thereby ensuring the reliability and effectiveness of the overall folding and retracting state of the filter structure.
[0063] In a specific embodiment, a hinge shaft is provided between any two adjacent filter frames 12, and the axes of the hinge shafts are arranged in parallel. Figure 1 、 Figure 5 The filter frame 12 includes two oppositely disposed first ends and two oppositely disposed second ends. The first ends of any two adjacent filter frames 12 are hinged via a hinge shaft, and the second ends are used to connect to the support assembly 2 .
[0064] If the filter frame 12 is a rectangular structure for example, the first end is the length direction of the rectangular structure, and the second end is the width direction of the rectangular structure.
[0065] By arranging the axes of the hinge shafts in parallel, the sides of the filter frame 12 can be reliably supported by the support assembly 2, and the edges of the filter 11 are pressed against the dead-edge structure of the filter frame 12. This also provides reliable support for the filter 11, preventing damage to the filter 11 and ensuring the service life and reliable operation of the filter 11. For example, when used in a cooling unit, the edges of each filter 11 can be reliably supported by the filter frame 12 and the support assembly 2, preventing damage and detachment of the filter structure during unit operation vibration, which could affect the normal operation of the unit.
[0066] Based on any of the above embodiments, please refer to Figure 1 Any two adjacent filter frames 12 are connected by a hinge 13, and the hinge 13 specifically includes a first hinge piece, a second hinge piece and a hinge axis. The first hinge piece is hingedly connected to the second hinge piece through the hinge axis. The first hinge piece is connected to the first end of one of the two adjacent filter frames 12, and the second hinge piece is connected to the first end of the other of the two adjacent filter frames 12.
[0067] The specific location of the hinge 13 can be determined based on ensuring the reliable stability of the overall rotation of the entire filter structure, such as being located in the middle and end of the filter frame 12 , or at both ends of the filter frame 12 .
[0068] Based on any of the above embodiments, multiple hinges 13 are arranged along the first end of the filter frame 12 to ensure reliable stability of rotation between two adjacent filter frames 12 and ensure smoothness and speed of installation and disassembly operations.
[0069] The width of the first hinge piece and the second hinge piece are both smaller than the frame width of the filter screen frame 12, so that the first hinge piece and the second hinge piece will not interfere with the filter screen 11, will not fold or block the filter screen 11, and ensure the reliable operation effect of the filter screen 11.
[0070] In addition to the above-mentioned filter structure 1, the present invention also provides a cooling unit including the filter structure 1 disclosed in the above-mentioned embodiment.
[0071] Based on any of the above embodiments, please refer to Figure 2-4 The cooling unit also includes: a frame 3; a core 4, which is arranged on the frame 3; a support assembly 2, which is connected to the frame 3 and is located on the upper side of the core 4; a condenser 5, which is located on the upper side of the support assembly 2, that is, the core 4, the support assembly 2, and the condenser 5 are arranged in sequence from bottom to top.
[0072] The filter structure 1 is installed in the installation cavity of the support assembly 2. After the filter structure 1 is installed in the support assembly 2, it is located between the core 4 and the condenser 5 to achieve the effect of filtering and removing impurities from the airflow passing through the core 4.
[0073] like Figure 3 A maintenance access 8 is provided on the frame 3. This access 8 is a specific arrangement for operators to stand and remove and install the filter structure 1 installed in the mounting cavity of the support assembly 2. With the filter structure 1 provided in this application, only one set of filter structures 1 is required for each core 4, and the filter screens 11 of each set of filter structures 1 are reliably supported, giving the filter structure 1 good structural strength and effectively avoiding the problem of the connection points being unable to be fixed and supported during the actual installation of conventional multiple filter screens.
[0074] On the basis of any of the above embodiments, the cooling unit further includes a filter maintenance port 6 provided on the frame 3 , and the filter structure 1 can be extended into or removed from the installation cavity through the filter maintenance port 6 .
[0075] During installation, the installation and maintenance personnel stand on the maintenance channel 8 and install the filter structure 1 and the water collector 9 in the installation cavity corresponding to the support component 2; during maintenance, the installation and maintenance personnel stand on the maintenance channel 8 and remove the filter structure 1 from the filter maintenance port 6 for repair or replacement. After repair and replacement, the intact filter structure 1 can be installed from the filter maintenance port 6 into the installation cavity corresponding to the support component 2.
[0076] Since the filter structure 1 is foldable as a whole, the installation and maintenance personnel can stand on the maintenance channel 8 to extend the filter structure 1 into or remove it from the installation cavity of the support assembly 2 from the filter maintenance port 6 to realize the installation and disassembly of the filter structure 1. The installation and maintenance personnel can perform rapid disassembly and maintenance in a small space, thereby improving the installation and disassembly efficiency.
[0077] Based on any of the above embodiments, please refer to Figure 2 、 Figure 5 The support assembly 2 includes a main body, a transverse connecting portion 22, and an installation portion 21. The transverse connecting portion 22 is provided in the transverse direction of the main body. The transverse connecting portion 22 is provided with an opening connected to the filter maintenance port 6. The filter structure 1 is moved into or out of the installation cavity of the support assembly 2 from the opening of the transverse connecting portion 22, and the filter structure 1 is further taken out or put into the filter maintenance port 6 to perform installation and disassembly operations of the filter structure 1.
[0078] The main body is longitudinally connected to the frame 3 and is provided with a mounting portion 21, which is slidably connected to the second end of the filter frame 12. The sliding connection between the second end of the filter frame 12 and the mounting portion 21 facilitates pushing and pulling the filter structure 1, achieving rapid installation and removal of the filter structure 1.
[0079] Specifically, a slide groove can be set in the installation part 21, and the filter frame 12 of the filter structure 1 is connected to the slide groove. It can be quickly slid into place during installation. After sliding into place, the filter structure 1 is relatively fixed on the support assembly 2; when disassembling, the filter structure 1 is manually pulled to make it slide quickly out of the slide groove and removed from the filter maintenance port 6.
[0080] On the basis of any of the above embodiments, the frame 3 is connected to a sealing plate 7 , and the sealing plate 7 is provided with a filter maintenance port 6 .
[0081] By setting a sealing plate 7, a sealing effect is achieved in the space where the condenser 4 at the upper end of the core 4 is located. When the cooling unit is in use, the air duct from the outdoor air through the core 4 to the filter structure 1 to the condenser 5 is relatively closed, ensuring reliable heat exchange for the condenser 5. The airflow after heat exchange is blown out through the fan or other components on the upper side of the condenser 5.
[0082] During installation and maintenance work, the filter maintenance port 6 on the sealing plate 7 is opened; when the cooling unit is operating normally, the filter maintenance port 6 is closed to ensure the sealing effect.
[0083] The filter maintenance port 6 can be closed and opened by a component of the sealing plate 7 (the sealing plate 7 itself has a component for sealing or opening the filter maintenance port 6), or by other components (such as a sealing plate provided independently of the sealing plate 7).
[0084] On the basis of the above embodiment, further, the sealing plate 7 includes a first sealing plate and a second sealing plate connected thereto, please refer to Figure 2 、 Figure 4 The first sealing plate is detachably connected to the frame 3 and is mainly used for disassembly and maintenance of the water collector 9. The filter maintenance port 6 is provided on the first sealing plate, and the second sealing plate is detachably connected to the first sealing plate to block or open the filter maintenance port 6 to realize disassembly and maintenance of the filter structure 1.
[0085] When disassembling and repairing the filter structure 1 , the installation and maintenance personnel stand on the maintenance channel 8 and remove the second sealing plate to expose the filter maintenance port 6 , thereby achieving the effect of disassembling the filter structure 1 on the support assembly 2 .
[0086] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0087] The above is a detailed introduction to the filter structure and cooling unit provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention. It should be pointed out that, for those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
