Description

Technical Field

[0001] This invention relates to the field of server rack technology, specifically to a multi-airflow heat dissipation information room network server rack. Background Technology

[0002] Information server room network cabinets are standard rack-type structures used for centralized installation, management and protection of network equipment. They are the core infrastructure of modern data centers, server rooms and network equipment rooms. Multi-airflow cooling information server room network cabinets are designed by dividing the interior of the cabinet into multiple independent or interconnected airflow channels, breaking away from the traditional single air intake and exhaust channel design. The internal space of the cabinet is divided into multiple airflow channels through components such as partitions and air guides. In existing server racks, air intake channels are usually set on both sides of the rack to allow outside air to enter the rack from both sides. At the same time, the devices inside the rack are close together, with little gap for air circulation. When the air enters from both sides, it flows horizontally without guidance and is directly driven by the fan to flow upward from both sides, resulting in the inability to dissipate heat in the center of the rack. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multi-airflow heat dissipation information room network cabinet, comprising: The cabinet has slots on both sides and an internal support mechanism installed inside. An air inlet mechanism and an air outlet mechanism are provided. The air outlet mechanism is installed on the top of the cabinet, and the air inlet mechanism is installed in the slots on both sides of the cabinet. The air intake mechanism includes a fixed frame, which is fixedly installed in the slot of the cabinet. The inner wall of the fixed frame is fixedly installed with a slot plate. The outer side of the slot plate is evenly provided with rectangular slots from top to bottom. An air intake hood is fixedly installed in each of the rectangular slots of the slot plate. The end of the air intake hood away from the slot plate is bent vertically downwards. The inner wall of the air intake hood is fixedly installed with a through slot plate. The outer side of the through-slot plate is evenly provided with through slots, and the through-slot plate is inclined from top to bottom towards one side of the cabinet inside the air inlet hood. The side of the through-slot plate away from the cabinet has a plate groove, and a filter plate is fixedly installed in the plate groove of the through-slot plate. An air guide plate is fixedly installed on the inner wall of the air inlet hood. The air guide plate is inclined from top to bottom towards one side of the cabinet. Through the air guide plate, the filter plate and the through-slot plate, the filter plate filters the incoming air. After the air is filtered, it passes through the filter plate and then through the through slot of the through-slot plate, entering the gap between the air guide plate and the through-slot plate. The air guide plate restricts the air, causing the air to be guided obliquely downwards, so that the air enters the cabinet at an oblique angle. With the help of the internal support mechanism to separate the internally installed equipment, the incoming air flows obliquely downwards and enters the gap between the equipment. This avoids the air entering the cabinet only staying on the sides of the cabinet and then flowing directly upwards to be discharged, which would prevent the center of the cabinet from being effectively cooled. The air guide plate is located on the side of the through-slot plate closer to the cabinet.

[0004] Preferably, a grooved plate is fixedly installed at the bottom of the inner wall of the air inlet hood. The bottom end of the grooved plate is inclined towards one side of the cabinet, and grooves are evenly opened on the outer side of the grooved plate. The grooved plate is located directly below the filter plate. A dust collection hood is fixedly installed at the bottom of the inner wall of the air inlet hood. The side of the dust collection hood near the grooved plate is inclined from bottom to top towards the grooved plate. Through the cooperation of the dust collection hood and the grooved plate, after the air is initially filtered by the grooves of the grooved plate, it enters the interior of the air inlet hood. During the upward flow, the inclination of the side of the dust collection hood near the grooved plate guides the incoming air, preventing the air from directly rushing into the interior of the dust collection hood and causing the dust collected by the dust collection hood to be blown away and scattered. The bottom of the side of the dust collection hood near the grooved plate is in contact with the bottom of the grooved plate.

[0005] Preferably, the air outlet mechanism includes a fixed cylinder, which is fixedly installed on the top of the cabinet, with its bottom end penetrating the cabinet and extending into its interior. A top cover plate is fixedly installed on the top of the fixed cylinder, and the top of the top cover plate has symmetrically formed circular slots. Air guide tubes are fixedly installed in each of the circular slots of the top cover plate. An air outlet ring is fixedly installed on the top of the air guide tube, and a top cover plate is fixedly installed on the top of the air outlet ring. A slotted plate is fixedly installed on the inner wall of the air guide tube, and a motor is fixedly installed at the center of the bottom of the slotted plate. The output end of the motor passes through… The motor output end is fixedly equipped with a fan wheel, which extends through the slotted tray to its top. The outer side of the air outlet ring is evenly provided with air outlet holes. The air outlet ring cooperates with the top cover plate. By utilizing the characteristic that the outer diameter of the air outlet ring gradually decreases from top to bottom, and the characteristic that the outer diameter of the top cover plate is larger than the outer diameter of the air outlet ring, it is possible to prevent dust or foreign objects falling from the top from being blocked by the top cover plate. At the same time, when there are dripping water droplets, it is possible to limit the entry of water droplets, preventing foreign objects or water droplets from entering the cabinet and causing damage to the internal equipment. The outer diameter of the air outlet ring gradually decreases from top to bottom, and the outer diameter of the top cover plate is larger than the outer diameter of the air outlet ring.

[0006] Preferably, the internal support mechanism includes a support frame, the bottom of which is fixedly connected to the bottom of the inner wall of the cabinet. A partition plate is fixedly installed on the inner wall of the support frame. The partition plate is evenly installed from top to bottom inside the support frame. A rectangular groove is formed at the center of the top of the partition plate, and grooves are evenly formed at the rectangular groove. By cooperating with the grooves, the rectangular groove forms an airflow gap at the bottom of the equipment during equipment installation. When air enters from both sides, the air can pass through the grooves at the bottom of the partition plate, contact the bottom of the equipment, and absorb the heat at the bottom of the equipment, thus preventing the bottom of the equipment from being unable to dissipate heat. A wire-passing frame is fixedly installed on both sides of the support frame. The wire-passing frame is evenly installed on both sides of the support frame and is located between the partition plates.

[0007] Preferably, a groove is provided at the bottom of the inner wall of the wire threading frame, and a rotating shaft is rotatably installed on the side of the inner wall of the wire threading frame near the partition plate. A rotating cylinder is fixedly installed on the outer side of the rotating shaft. An inner slide strip is slidably installed at the groove of the wire threading frame. A rubber pad is fixedly installed between the bottom of the inner slide strip and the inner wall of the wire threading frame. Through the cooperation of the top wire plate and the rubber plate, after the wire harness is installed, the rubber pad lifts the inner slide strip, so that the top wire plate lifts the wire harness and cooperates with the rubber plate to clamp the wire harness. At the same time, when the wire harness is pulled, the pressure is transmitted to the rubber pad through the top wire plate to buffer the pulling force and protect the wire harness. A top wire plate is fixedly installed on the top of the inner slide strip. The top of the top wire plate is a sloping surface with a central protrusion. A rubber plate is fixedly installed on the top of the inner wall of the wire threading frame. The rubber plate is located directly above the top wire plate.

[0008] This invention provides a multi-airflow heat dissipation network cabinet for information data centers. It has the following beneficial effects: (i) This multi-channel heat dissipation information room network cabinet uses air guide plates, filter plates, and through slot plates. The filter plates filter the incoming air, and the filtered air passes through the filter plates and through the slot plates, entering the gap between the air guide plates and the through slot plates. The air guide plates restrict the airflow, causing the air to flow downwards and into the cabinet. Combined with the internal support mechanism that separates the internal equipment, the incoming air flows downwards and into the gaps between the equipment. This prevents the air from only staying on the sides of the cabinet and then flowing upwards, which would otherwise prevent effective heat dissipation in the center of the cabinet.

[0009] (ii) The information room network cabinet with multi-channel heat dissipation uses a dust collection hood and a slotted plate to cooperate. After the air passes through the slots of the slotted plate for preliminary filtration, it enters the interior of the air intake hood. During the upward flow, the tilt of the dust collection hood near the slotted plate guides the incoming air, preventing the air from rushing directly into the dust collection hood and causing the dust collected by the dust collection hood to be blown away and scattered.

[0010] (III) The multi-airflow cooling information room network cabinet, through the cooperation of the exhaust ring and the top cover plate, takes advantage of the characteristic that the outer diameter of the exhaust ring gradually decreases from top to bottom, and the characteristic that the outer diameter of the top cover plate is larger than the outer diameter of the exhaust ring, to prevent dust or foreign objects falling from the top from being blocked by the top cover plate. At the same time, when there are dripping water droplets, it restricts the water droplets from entering, preventing foreign objects or water droplets from entering the cabinet and causing damage to the internal equipment.

[0011] (iv) The multi-channel heat dissipation information room network cabinet, through the cooperation of the rectangular groove and the slot of the partition plate, forms an air flow gap at the bottom of the equipment when the equipment is installed. When air is introduced from both sides, the air can pass through the partition plate through the slot at the bottom of the partition plate and contact the bottom of the equipment to absorb the heat at the bottom of the equipment, thus avoiding the bottom of the equipment from being unable to dissipate heat.

[0012] (v) The multi-airflow heat dissipation information room network cabinet uses a top cable plate and a rubber plate to cooperate. After the wire harness is installed, the rubber pads lift the inner sliding strips, so that the top cable plate lifts the wire harness and cooperates with the rubber plate to clamp the wire harness. At the same time, when the wire harness is pulled, the pressure is transmitted to the rubber pads through the top cable plate to buffer the pulling force and protect the wire harness.

After the air is filtered, it passes through the filter plate 25 and then through the through slot of the through-slot plate 26, and enters the space between the through-slot plate 26 and the air guide plate 27. Finally, under the restriction of the air guide plate 27, the air is guided so that the air enters the interior of the cabinet 1 obliquely downward. The filter plate 25 is fixedly installed at the plate groove of the through-slot plate 26, and the air guide plate 27 is fixedly installed on the inner wall of the air inlet hood 23.

[0017] A grooved plate 24 is fixedly installed at the bottom of the inner wall of the air inlet hood 23. The bottom end of the grooved plate 24 is inclined towards one side of the cabinet 1, and grooves are evenly opened on the outer side of the grooved plate 24. The grooved plate 24 is located directly below the filter plate 25. When the outside air flows inside the cabinet 1, the air is initially filtered by the grooved plate 24 at the bottom of the air inlet hood 23. After the air passes through the grooves of the grooved plate 24, it enters the interior of the air inlet hood 23. After entering the interior of the air inlet hood 23, the inclined surface of the dust collection hood 28 near the grooved plate 24 cooperates with the grooved plate 24 to guide the incoming air, so that the air flows obliquely upward to contact the filter plate 25. A dust collection hood 28 is fixedly installed at the bottom of the inner wall of the air inlet hood 23. The side of the dust collection hood 28 near the grooved plate 24 is inclined from bottom to top towards the grooved plate 24, and the bottom of the side of the dust collection hood 28 near the grooved plate 24 is in contact with the bottom of the grooved plate 24.

[0018] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 7As shown, the air outlet mechanism 3 includes a fixed cylinder 31, which is fixedly installed on the top of the cabinet 1. The bottom end of the fixed cylinder 31 penetrates the cabinet 1 and extends into the interior of the cabinet 1. A top cover plate 34 is fixedly installed on the top of the fixed cylinder 31. A circular groove is symmetrically opened on the top of the top cover plate 34. An air guide tube 32 is fixedly installed in each of the circular grooves of the top cover plate 34. The fan wheel 37 is driven by the motor 38 to rotate inside the air guide tube 32, causing the air inside the cabinet 1 to move upward under the drive of the fan wheel 37, pass through the fixed cylinder 31 and enter the interior of the air guide tube 32. An air outlet ring 33 is fixedly installed on the top of the air guide tube 32, and a top cover plate 35 is fixedly installed on the top of the air outlet ring 33. A through groove plate 36 is fixedly installed on the inner wall of the air guide tube 32.

The plate 36 extends to its top, and the output end of the motor 38 is fixedly equipped with a fan wheel 37. The outer side of the air outlet ring 33 is evenly provided with air outlet holes, and the outer diameter of the air outlet ring 33 gradually decreases from top to bottom. After the air enters the air guide tube 32, it first passes through the through slot plate 36, and then the air flows to the bottom of the top cover plate 35. Then, under the restriction of the top cover plate 35, it flows to all sides. During the flow, it contacts the inner wall of the air outlet ring 33, and then is discharged through the evenly provided air outlet holes on the outer side of the air outlet ring 33. At the same time, during the operation, the top cover plate 35 cooperates with the air outlet ring 33. The characteristic that the outer diameter of the air outlet ring 33 gradually decreases from top to bottom, and the characteristic that the outer diameter of the top cover plate 35 is larger than the outer diameter of the air outlet ring 33, to block the dust falling from the top and restrict the dust and foreign objects from entering the cabinet 1. The outer diameter of the top cover plate 35 is larger than the outer diameter of the air outlet ring 33.

[0019] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 10 As shown, the internal support mechanism 4 includes a support frame 41. The bottom of the support frame 41 is fixedly connected to the bottom of the inner wall of the cabinet 1. A partition plate 42 is fixedly installed on the inner wall of the support frame 41. The partition plate 42 is evenly installed from top to bottom inside the support frame 41. A rectangular groove is opened at the center of the top of the partition plate 42, and a groove is evenly opened in the rectangular groove of the partition plate 42. A wire-passing frame 43 is fixedly installed on both sides of the support frame 41. When installing equipment, the equipment is installed on the top of the partition plate 42, and the partition plate 42 separates the equipment. At the same time, when installing equipment, the rectangular groove at the center of the top of the partition plate 42 cooperates with the groove to form an air flow gap at the bottom of the equipment. When the air intake mechanism 2 on both sides introduces outside air into the interior of the cabinet 1, the air between the partition plates 42 flows upward, passes through the groove, enters the rectangular groove, and contacts the bottom of the equipment. The wire-passing frame 43 is evenly installed on both sides of the support frame 41 and is located between the partition plates 42.

[0020] A groove is provided at the bottom of the inner wall of the wire guide frame 43, and a rotating shaft 45 is rotatably installed on the side of the inner wall of the wire guide frame 43 near the partition plate 42. A rotating cylinder 46 is fixedly installed on the outside of the rotating shaft 45. An inner slide strip 48 is slidably installed at the groove of the wire guide frame 43. A rubber pad 49 is fixedly installed between the bottom of the inner slide strip 48 and the inner wall of the wire guide frame 43. When installing the equipment wiring, the wiring passes through the wire guide frames 43 on both sides and cooperates with the top wire plate 44 through the rubber pad 49. The rubber pad 49 lifts the inner slide strip 48, so that the inner slide strip 48 drives the top wire plate 44 to cooperate with the rubber plate 47 at the top of the inner wall of the wire guide frame 43 to clamp the wiring. The top wire plate 44 is fixedly installed on the top of the inner slide strip 48. The top of the top wire plate 44 is a sloping surface with a central protrusion. The rubber plate 47 is fixedly installed on the top of the inner wall of the wire guide frame 43. The rubber plate 47 is located directly above the top wire plate 44.

[0021] When in use, the equipment that needs to be installed inside the cabinet is installed and supported and fixed by the internal support mechanism 4. When the equipment is working, the air inside the cabinet is driven out to the outside by the air outlet mechanism 3, which reduces the air pressure inside the cabinet 1. The outside air flows into the inside of the cabinet 1 through the air inlet mechanisms 2 on both sides under atmospheric pressure, so that the air inside and outside the cabinet 1 is exchanged, and the heat generated by the internal equipment during operation is carried away for heat dissipation.

[0022] In the air intake mechanism 2, when the outside air flows inside the cabinet 1, the air is initially filtered by the grooved plate 24 at the bottom of the air intake hood 23. After passing through the grooves of the grooved plate 24, the air enters the interior of the air intake hood 23. After entering the interior of the air intake hood 23, the inclined surface of the dust collection hood 28 near the grooved plate 24 cooperates with the grooved plate 24 to guide the incoming air, causing the air to flow obliquely upward to contact the filter plate 25. The air is filtered again by the filter plate 25. After the air is filtered, it passes through the filter plate 25 and passes through the groove of the through plate 26, entering the space between the through plate 26 and the air guide plate 27. Finally, under the restriction of the air guide plate 27, the air is guided to enter the interior of the cabinet 1 obliquely downward.

[0023] In the air outlet mechanism 3, the fan wheel 37 is driven by the motor 38 to rotate inside the air guide tube 32, causing the air inside the cabinet 1 to move upward under the drive of the fan wheel 37, pass through the fixed tube 31 and enter the interior of the air guide tube 32. After entering the interior of the air guide tube 32, the air first passes through the through slot plate 36, and then the air flows to the bottom of the top cover plate 35. Then, under the restriction of the top cover plate 35, it flows to all sides. During the flow, it comes into contact with the inner wall of the air outlet ring 33, and then is discharged through the air outlet holes evenly opened on the outer side of the air outlet ring 33. At the same time, during the operation, the top cover plate 35 cooperates with the air outlet ring 33. The outer diameter of the air outlet ring 33 gradually decreases from top to bottom, and the outer diameter of the top cover plate 35 is larger than the outer diameter of the air outlet ring 33, which blocks the dust falling from the top and restricts the entry of dust and foreign objects into the interior of the cabinet 1.

[0024] In the internal support mechanism 4, when installing equipment, the equipment is installed on top of the partition plate 42, which separates the equipment. At the same time, when installing equipment, a rectangular groove and a slot are provided at the center of the top of the partition plate 42 to form an airflow gap at the bottom of the equipment. When the air intake mechanism 2 on both sides introduces outside air into the cabinet 1, the air between the partition plates 42 flows upward, passes through the slot, enters the rectangular groove, and contacts the bottom of the equipment. At the same time, when installing the equipment wiring, the wiring passes through the wire guide frame 43 on both sides and cooperates with the top wire plate 44 through the rubber pad 49. The rubber pad 49 lifts the inner slide 48, causing the inner slide 48 to drive the top wire plate 44, which cooperates with the rubber plate 47 on the top of the inner wall of the wire guide frame 43 to clamp the wiring.
