Description

Technical Field

[0001] This utility model relates to the field of computer room ventilation technology, specifically a computer room constant temperature ventilation component. Background Technology

[0002] As computer rooms become more widely used and the number of devices inside them continues to increase, the heat inside the computer room will rise rapidly as the devices operate for a long time. Therefore, ventilation components are needed to ventilate and cool the computer room.

[0003] Chinese utility model patent CN221081845U discloses a constant temperature ventilation component for data centers. By installing a fan and a dust filter inside the ventilation duct, cool air from outside is guided into the data center by the fan. An adjustment component is installed at the duct opening to adjust the size of the opening into the ventilation duct, thus maintaining a constant temperature inside the data center. However, during use, the dust filter easily accumulates impurities, and cleaning can only be done by disassembling it. If cleaning is too frequent, it will increase the workload. If the dust is cleaned too infrequently, the fan will operate under overload for too long, which may cause damage. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a computer room constant temperature ventilation component.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The dustproof component includes a dustproof net that is rotatably installed inside the ventilation channel, and the dustproof net always covers the cross section of the ventilation channel during rotation.

[0007] A cleaning mechanism that can reciprocate along the dustproof net is installed on the outside of the dustproof net. The cleaning mechanism is located below the dustproof net and in contact with the surface of the dustproof net. A dust collection channel is installed below the cleaning mechanism to collect the dust that falls during cleaning.

[0008] Furthermore, the dustproof net is ring-shaped, and a first control component is provided on the inner side of the dustproof net to drive the dustproof net to rotate and adjust its position.

[0009] Furthermore, the cleaning mechanism includes a first cleaning plate disposed at the bottom of the outer side of the dustproof net, and the shape of the first cleaning plate is adapted to the side of the dustproof net that is in contact with it. A second control component is disposed on the first cleaning plate for driving the first cleaning plate to slide back and forth along a straight line on the surface of the dustproof net to clean the outer side of the dustproof net.

[0010] Furthermore, the cleaning mechanism also includes a second cleaning plate disposed at the bottom inner side of the dustproof net, and the shape of the second cleaning plate is adapted to the end of the dustproof net that is in contact with it. One side of the second cleaning plate is connected to a third control component, which is used for the second cleaning plate to slide back and forth along a straight line on the surface of the dustproof net to clean the inner side of the dustproof net.

[0011] Furthermore, the second control component and the third control component each include two sets of threaded rods and limiting rods disposed at the entrance of the dust collection channel. The two sets of limiting rods pass through one side of the first cleaning plate and the second cleaning plate respectively, and are used to limit the rotation of the first cleaning plate and the second cleaning plate. The first cleaning plate and the second cleaning plate are respectively threadedly connected to the corresponding threaded rods. The end of the threaded rod is provided with a second driving structure, which is used to drive the first cleaning plate and the second cleaning plate to reciprocate along the axis of the threaded rod.

[0012] Furthermore, protective covers are provided at both ends of the limiting rod, the top of the protective covers are fixedly connected to the side wall of the dust collection channel, and the second drive structure is located inside the protective cover. The protective cover is rotatably connected to the end of the threaded rod.

[0013] Furthermore, the interior of the outer casing is provided with a first partition to divide the interior of the outer casing into two channels, namely a storage channel located below and a ventilation channel located above.

[0014] The first partition has a second opening on its surface directly below the dustproof net, forming a dust collection channel to connect the storage channel and the ventilation channel, so that the cleaned dust can enter the storage channel.

[0015] The second opening is also equipped with a flow guide structure that extends upward through the ventilation channel. The dustproof net is located on the flow guide structure so that air can pass through the dustproof net and enter the computer room.

[0016] Furthermore, the flow guiding structure includes a closed limiting frame, the bottom and top of which are connected to the second opening and the top of the outer shell, respectively. The limiting frame has a third opening that runs through the ventilation channel. The dustproof net is located inside the third opening and its two ends are rotatably connected to the inner wall of the limiting frame, respectively.

[0017] The inner wall of the limiting frame is provided with two symmetrical second partitions, both of which are located inside the dustproof net, and the two opposite edges of the second partitions are slidably connected to the inner wall of the dustproof net.

[0018] The bottom of the limiting frame has a first opening so that the interior of the limiting frame can communicate with the dust collection channel through the first opening;

[0019] The width of the limiting bracket is the same as the width of the ventilation channel, used to restrict airflow so that air can move through the dustproof net.

[0020] Furthermore, the first control component includes a gear ring, the outer side of which is fixedly connected to the inner wall of the dustproof net, and a gear meshing with the inner side of the gear ring. A first drive structure is provided on one side of the gear, and the bottom of the first drive structure is fixedly connected to the top of the upper second partition plate for driving the dustproof net to rotate and adjust its position.

[0022] Compared with existing technologies, this computer room temperature control and ventilation system has the following advantages:

[0023] I. This utility model uses a rotating dustproof net to adjust the area of ​​the dustproof net facing the direction of the airflow, moving the used area to the corresponding position of the cleaning mechanism. The cleaning mechanism moves on the surface of the dustproof net to wipe and clean it, causing the dust to fall off, thereby achieving self-cleaning of the dustproof net. This solves the problem that existing dustproof nets easily attract impurities, and cleaning can only be done by disassembly, which is inconvenient.

[0024] Second, this utility model divides the outer shell into two different areas, upper and lower, through the first partition, and sets a storage box at the bottom, so that when cleaning dust, the dust falls into the storage box. The storage box can be taken out and emptied by disassembling the mounting plate, so as to facilitate long-term cleaning and collection and improve the use effect. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] like Figure 1-5 As shown, this utility model provides a technical solution: a computer room constant temperature ventilation component, including a housing 1, with a ventilation channel inside the housing 1, and a dustproof component inside the ventilation channel. The dustproof component includes a dustproof net 7 rotatably disposed inside the ventilation channel, which always covers the cross-section of the ventilation channel during rotation; a cleaning mechanism that can reciprocate along the dustproof net 7 is disposed on the outside of the dustproof net 7, and the cleaning mechanism is located below the dustproof net 7 and in contact with the surface of the dustproof net 7; a dust collection channel is disposed below the cleaning mechanism for collecting the dust that falls during cleaning; the dustproof net 7 is annular in shape, and a first control component is disposed on the inner side of the dustproof net 7 for... The dustproof net 7 is rotated to adjust its position; the cleaning mechanism includes a first cleaning plate 11 located at the bottom outer side of the dustproof net 7, and the shape of the first cleaning plate 11 is adapted to the side of the dustproof net 7 that is in contact with it. A second control component is provided on the first cleaning plate 11 for driving the first cleaning plate 11 to slide back and forth along a straight line on the surface of the dustproof net 7 to clean the outer side of the dustproof net 7; a second cleaning plate is provided on the inner side of the dustproof net 7, and the shape of the second cleaning plate is adapted to the end of the dustproof net 7 that is in contact with it. One side of the second cleaning plate is connected to a third control component for the second cleaning plate to slide back and forth along a straight line on the surface of the dustproof net 7 to clean the inner side of the dustproof net 7.

[0033] When in use, the dustproof net 7 is a ring that spans the ventilation channel. When it is used to prevent dust, air enters from one side of the ventilation channel, then passes through the small holes on the side of the dustproof net 7 and enters the middle of the ring. Dust and impurities are blocked on one side of the dustproof net 7, and then continue to flow through the small holes on the opposite side of the ring and enter the computer room.

[0034] During cleaning: The dust filter 7 is driven to move by the first control component, causing the dust filter 7 to rotate around its own axis. The surface of the dust filter 7 facing the air intake is adjusted. As it rotates, the part that originally served as a filter moves to the position of the first cleaning plate 11 and the second cleaning plate. The second control component and the third control component control the first cleaning plate 11 and the second cleaning plate to reciprocate, wiping and cleaning the surface of the dust filter 7 and removing the dust.

[0035] In each rotation, since the length of the dustproof side of the dustproof net 7 is greater than the length of the contact area between the first cleaning plate 11 and the second cleaning plate and the dustproof net 7, and the second cleaning plate is located on the inside, the length adjusted in each rotation is less than the length of the second cleaning plate. For example, when the central angle corresponding to the arc of the second cleaning plate is 60 degrees, the rotation angle does not exceed 60 degrees each time to prevent the uncleaned part from moving to the other side of the second cleaning plate. The parts of the first cleaning plate 11 and the second cleaning plate that contact the dustproof net 7 are made of flexible bristles to reduce damage to the dustproof net 7 and facilitate long-term use.

[0036] The interior of the outer casing 1 is provided with a first partition 2, which is used to divide the interior of the outer casing 1 into two channels, namely the storage channel located below and the ventilation channel located above. The surface of the first partition 2 directly below the dustproof net 7 has a second opening, forming a dust collection channel, which is used to connect the storage channel and the ventilation channel so that the cleaned dust can enter the interior of the storage channel. A guide structure is also provided at the second opening, which extends upward and penetrates the ventilation channel. The dustproof net 7 is located on the guide structure so that air can pass through the dustproof net 7 and enter the computer room.

[0037] In use, the outer casing 1 is in the shape of a rectangular tube. A fan structure is installed at one port, and an adjustment component is installed at the other port to adjust the size of the opening so as to regulate the temperature in the computer room and maintain a constant temperature effect in the computer room. Its principle and structure can be referred to in CN221081845U, a constant temperature ventilation component for data center, which will not be elaborated on here.

[0038] The airflow guiding structure includes a closed limiting frame 5. The bottom and top of the limiting frame 5 are connected to the second opening and the top of the outer shell 1, respectively. The limiting frame 5 has a third opening that runs through the ventilation channel. The dustproof net 7 is located inside the third opening, and its two ends are rotatably connected to the inner wall of the limiting frame 5. The inner wall of the limiting frame 5 is provided with two symmetrical second partitions 6. Both second partitions 6 are located inside the dustproof net 7, and the two opposite edges of the second partitions 6 are slidably connected to the inner wall of the dustproof net 7. The bottom of the limiting frame 5 has a first opening 8, so that the interior of the limiting frame 5 can communicate with the dust collection channel through the first opening 8. The width of the limiting frame 5 is the same as the width of the ventilation channel, which is used to restrict the passage of air so that the air can move through the dustproof net 7.

[0039] In use, the two sides of the middle of the limiting frame 5 are disc-shaped, with a diameter slightly larger than that of the dustproof net 7. Sealing strips, in annular shape, are installed at the contact points with both ends of the dustproof net 7 to achieve a sealing effect. The width of the contact surfaces between the second partition 6 and the limiting frame 5 and the curved surface of the dustproof net 7 is greater than the diameter of a small hole in the dustproof net 7 and the gap between that small hole and the small holes on both sides. This ensures that the contact points between the second partition 6 and the limiting frame 5 and the dustproof net 7 always maintain a sealed position, preventing airflow. Simultaneously, at the lower... At the two contact points between the square limiting frame 5 and the dustproof net 7, a small gap is left between the position closer to the airflow direction and the dustproof net 7, so that the dust on the dustproof net 7 can move to the first cleaning plate 11 as the dustproof net 7 rotates, and then be cleaned, allowing the dust to enter the storage channel; at the same time, the contact parts of the other three positions with the dustproof net 7 are all equipped with sealing strips to improve the sealing effect and restrict the airflow, so that the air entering passes through the corresponding dustproof net 7 between the two second partitions 6, so that the dustproof net 7 can play the role of blocking dust.

[0040] The first control component includes a toothed ring 10, the outer side of which is fixedly connected to the inner wall of the dust filter 7. A gear 9 is meshed with the inner side of the toothed ring 10. A first drive structure is provided on one side of the gear 9. The bottom of the first drive structure is fixedly connected to the top of the upper second partition 6, which is used to drive the dust filter 7 to rotate and adjust its position. In use, the first drive structure is an electric motor. The output end of the electric motor drives the gear 9 to rotate, the gear 9 drives the toothed ring 10 to rotate, and the toothed ring 10 further drives the dust filter 7 to rotate, thereby adjusting the area of ​​the dust filter 7 facing the airflow direction. The used part is moved to the bottom for cleaning, and the cleaned part moves back to the airflow direction after multiple rotations, avoiding the need for frequent disassembly and cleaning. At the same time, an arc-shaped L-shaped sealing gasket is provided at the part of the bottom toothed ring 10 that contacts the second partition 6. The length of the gasket is at least greater than the length of two teeth, which further enhances the sealing between the toothed ring 10 and the second partition 6. The toothed ring 10 is much smaller than the width of the dust filter 7 to avoid affecting the filtration effect.

[0041] The bottom of the limiting frame 5 has a first opening 8; the second control component and the third control component include two sets of threaded rods 12 and limiting rods 13 set at the entrance of the dust collection channel. The two sets of limiting rods 13 pass through one side of the first cleaning plate 11 and the second cleaning plate respectively, and are used to limit the rotation of the first cleaning plate 11 and the second cleaning plate. The first cleaning plate 11 and the second cleaning plate are respectively threadedly connected to the corresponding threaded rods 12. The end of the threaded rod 12 is provided with a second driving structure, which is used to drive the first cleaning plate 11 and the second cleaning plate to reciprocate along the axis of the threaded rod 12.

[0042] In use, the bottom of the first cleaning plate 11 can be fixedly connected to an L-shaped plate, extending its bottom towards the outside of the dust collection channel. Then, a threaded rod 12 is positioned at the end of the L-shaped plate, placing it outside the dust collection channel to prevent dust from falling directly onto the threaded rod 12. Alternatively, a downward-opening arc-shaped cover can be installed on the threaded rod 12 to shield it, and then the cover is fixedly connected to the first cleaning plate 11 below. The second drive structure is a forward and reverse motor. There are two threaded rods 12, distributed vertically, located on the inner and outer sides of the bottom curved surface of the dustproof net 7, respectively. The bristles on the upper and lower first cleaning plates 11 and the second cleaning plate are staggered to facilitate the movement of dust from the first cleaning plate 11 and the second cleaning plate. During its movement, the second cleaning plate's bristles wipe the surface of the dustproof net 7, causing dust to fall downwards. The length of the first cleaning plate 11's movement is greater than the width of the small holes on the dustproof net 7, so that both the first and second cleaning plates can thoroughly wipe the dustproof area of ​​the dustproof net 7. The motor drives the threaded rod 12 to rotate in both directions, and under the positioning of the limit rod 13, the first cleaning plate 11 reciprocates on the rotating threaded rod 12, cleaning the dust on the dustproof net 7. The threaded rod 12 can be a bidirectional threaded rod, with a first cleaning plate 11 or a second cleaning plate on each of the two threaded parts to improve the cleaning efficiency of the dustproof net 7. A unidirectional threaded rod can also be used.

[0043] The two ends of the limiting rod 13 are respectively provided with protective covers 14. The top of the protective cover 14 is fixedly connected to the top of the first opening 8, and the second driving structure is located inside the protective cover 14. The protective cover 14 is rotatably connected to the end of the threaded rod 12.

[0044] In use, the protective cover 14 is equipped with pulleys and belts for power transmission. The first pulley is fixedly connected to the output end of the motor. The second and third pulleys are respectively mounted on the protective cover 14 at positions corresponding to the lower and upper threaded rods 12 via rotating shafts. The rotating shafts are collinear with the axes of the corresponding threaded rods 12. When there are two second drive structures, the two second drive structures output power to the upper and lower threaded rods 12 respectively. Specifically, in one protective cover 14, the lower rotating shaft is fixedly connected to the lower threaded rod 12, while the upper rotating shaft is in contact with it. In the other protective cover 14, the lower rotating shaft is in contact with the lower threaded rod 12, while the upper rotating shaft is fixedly connected to the upper threaded rod 12. When there is only one motor, power is output to two threaded rods 12 simultaneously. Specifically, the motor is installed inside one of the protective covers 14, and the two rotating shafts are fixedly connected to the two threaded rods 12 respectively, so that the motor drives the two threaded rods 12 to rotate via belt transmission.

[0045] The storage channel is equipped with a storage box 3 with a top opening, located below the first opening 8. Mounting plates 4 are detachably connected to both ends of the storage channel, with the sides of the two mounting plates 4 close to each other contacting the ends of the storage box 3 for positioning and fixing. During use, dust that falls through the cleaning process drops down through the first opening 8 and enters the storage box 3. After prolonged use, the storage box 3 can be removed by disassembling one of the mounting plates 4, and the dust can be emptied. The mounting plate 4 is connected to the outer casing 1 by a snap-fit ​​connection, and a sealing gasket is provided at the connection point to improve the sealing effect.
