Description

Technical Field

[0001] This utility model relates to the technical field of cooling auxiliary devices for OTN equipment, and in particular to an air guide cabinet for OTN equipment. Background Technology

[0002] OTN (Optical Transport Network) equipment is currently the mainstream equipment for Internet communication. OTN equipment is typically installed in OTN cabinets, which are equipped with air conditioning to prevent overheating.

[0003] Air ducts are typically installed inside server racks to assist in the cooling of OTN equipment. These air ducts are usually installed between two adjacent racks or between an air conditioner and a rack. They guide the cold airflow from the air conditioner vents into the racks, while the hot airflow generated inside the racks flows back to the air conditioner inlets. Existing air ducts have the following problems: the mixing of hot and cold airflows causes cross-contamination within the racks, thus affecting the cooling effect of the OTN equipment; and the high energy consumption of the air conditioners cannot meet the normal operating requirements of the OTN equipment. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the lack of isolation between cold and hot airflow in the existing cabinets, which affects the heat dissipation of OTN equipment, the purpose of this utility model is to provide a cabinet for OTN equipment that effectively isolates cold and hot airflow, improves heat dissipation, reduces air conditioning energy consumption, and meets the heat dissipation requirements of OTN equipment.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A ventilation cabinet for OTN equipment includes a frame, a first horizontal plate, a second horizontal plate, a first vertical plate, a second vertical plate, and a first exhaust component; The enclosure is shaped like an opening, and the first and second horizontal plates are both located inside the enclosure, dividing the enclosure into an upper section, a middle section and a lower section. The first vertical plate is located in the upper section and divides the upper section into an upper left channel and an upper right channel; The second vertical plate is located in the central area, dividing the central area into a left-center passage and a right-center passage; The first exhaust fan is located in the lower section and divides the lower section into a lower left channel and a lower right channel.

[0006] Furthermore, the air guide cabinet also includes a second exhaust component. The second vertical plate is provided with a first through hole, which connects the middle left channel and the middle right channel. The second exhaust component is located inside the first through hole.

[0007] Furthermore, the air guide cabinet also includes an upper air guide hood and a lower air guide hood. The upper air guide hood is located in the upper right channel, and the first horizontal plate has a first through hole, which connects the upper right channel and the middle right channel. The lower air guide hood is located in the lower right channel, and the second horizontal plate has a second through hole, which connects the lower right channel and the middle right channel.

[0008] Furthermore, the air guide cabinet also includes a first air baffle, which is located in the middle left channel and intersects with the second vertical plate.

[0009] Furthermore, both the upper and lower air guide hoods include an air gathering part, a connecting part, and an air outlet part connected in sequence. The air gathering part is slidably connected to the connecting part, and the connecting part is slidably connected to the air outlet part.

[0010] Furthermore, the air-gathering part has a concave arc surface, which is located away from the connecting part, and the air-discharging part has a convex arc surface, which is located away from the connecting part.

[0011] Furthermore, the air guide cabinet also includes a first baffle plate and a second baffle plate. The first baffle plate is located in the middle right channel and is connected to the surrounding frame, the first horizontal plate, and the second horizontal plate. The second baffle plate is located in the upper right channel and is connected to the surrounding frame and the first horizontal plate.

[0012] Furthermore, the air guide cabinet also includes a third air baffle, which is located in the lower left channel and is connected to the surrounding frame and the second horizontal plate.

[0013] One of the beneficial effects of this utility model is that by installing a first horizontal plate, a second horizontal plate, a first vertical plate, a second vertical plate, and a first exhaust fan inside the frame, the frame is divided into an upper left channel and an upper right channel, a middle left channel and a middle right channel, and a lower left channel and a lower right channel. The cold airflow enters the first and second set of cabinets through the middle right channel, while the hot airflow enters the return air vents of the external air conditioner through the upper left channel and the lower left channel, respectively. This effectively isolates the cold and hot airflows in the OTN equipment and improves the cooling effect.

[0014] The second beneficial effect of this utility model is that by setting a second exhaust component, an upper air guide hood, and a lower air guide hood inside the air guide cabinet, the cold airflow from the external air conditioning outlet is effectively diverted, ensuring that the cold airflow enters the middle right channel, improving the cooling effect, and increasing the flow rate of the cold airflow in the middle zone. The setting of the first baffle plate prevents the cold airflow from entering the air conditioner's return air vent, effectively isolating the cold and hot airflows.

[0015] The third beneficial effect of this utility model is that by installing a first baffle plate and a second baffle plate in the air guide cabinet, with the first baffle plate located in the middle right channel and the second baffle plate located in the upper right channel, the cold airflow is prevented from flowing upward from the lower right channel to the middle right channel and the upper right channel, ensuring that the cold airflow flows along the lower right channel to the external second set of mechanisms and the first set of cabinets, thus effectively guiding the cold airflow.

Detailed Implementation

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0019] Example 1.

[0020] Please see Figure 1a , Figure 1b and Figure 4a The present invention provides an air duct for OTN equipment, comprising a frame 1, a first horizontal plate 21, a second horizontal plate 22, a first vertical plate 31, a second vertical plate 32, and a first exhaust component 41. The frame 1 is shaped like an opening, and the first horizontal plate 21 and the second horizontal plate 22 are both located inside the frame 1, dividing the frame 1 into an upper section, a middle section and a lower section; The first vertical plate 31 is disposed in the upper region and divides the upper region into an upper left channel 1011 and an upper right channel 1012; The second vertical plate 32 is located in the middle area and divides the middle area into a left-middle channel 1021 and a right-middle channel 1022; The first exhaust component 41 is located in the lower area and divides the lower area into a lower left channel 1031 and a lower right channel 1032.

[0021] Specifically, in this embodiment, the air guide cabinet is placed between the first set of cabinets 100 and the second set of cabinets 200. The first set of cabinets 100, the air guide cabinet, and the second set of cabinets 200 are connected sequentially along the X direction. Both the first set of cabinets 100 and the second set of cabinets 200 are used to house external servers and other equipment. The air guide cabinet includes an opening-shaped frame 1, a first horizontal plate 21, and a second horizontal plate 22. The first horizontal plate 21 and the second horizontal plate 22 are installed in a parallel state at the top and bottom within the frame 1, dividing the frame 1 into an upper section, a middle section, and a lower section. A first vertical plate 31 is vertically arranged in the upper section, dividing the upper section into an upper left channel 1011 and an upper right channel 1012. A second vertical plate 32 is vertically arranged in the middle section, dividing the middle section into a middle left channel 1021 and a middle right channel 1022. The first exhaust component... 41 is vertically arranged in the lower area and the lower area is divided into the lower left channel 1031 and the lower right channel 1032. Preferably, the middle area is the cold air flow channel, and the upper and lower areas are the hot air flow channels. The working principle is as follows: the external air conditioner outlet corresponds to the middle right channel 1022. The cold air from the air conditioner outlet flows along the X direction through the middle right channel 1022. The cold air cools the server in the first set of cabinets 100 and the second set of cabinets 200. The hot air generated during the operation of the server flows upward and downward at the same time. Under the action of the first exhaust fan 41, the hot air flows to the air conditioner return air vent through the lower left channel 1031. Exhaust fans are installed on the top of the first set of cabinets 100 and the second set of cabinets 200 respectively so that the hot air at the top flows to the air conditioner return air vent through the upper left channel 1011.

[0022] By installing a first horizontal plate 21, a second horizontal plate 22, a first vertical plate 31, a second vertical plate 32, and a first exhaust fan 41 inside the enclosure 1, the enclosure 1 is divided into an upper left channel 1011 and an upper right channel 1012, a middle left channel 1021 and a middle right channel 1022, and a lower left channel 1031 and a lower right channel 1032. Cold air flows into the first set of cabinets 100 and the second set of cabinets 200 through the middle right channel 1022, while hot air flows into the return air vents of the external air conditioner through the upper left channel 1011 and the lower left channel 1031, respectively. This effectively isolates the cold and hot air in the OTN equipment inside the cabinets, improving the cooling effect.

[0023] Example 2.

[0024] Please see Figures 2a to 2d and Figure 4a The air guide cabinet of this utility model is placed between the air conditioner 300 and the second set of cabinets 200. The air conditioner 300, the air guide cabinet and the second set of cabinets 200 are connected in sequence along the X direction. The air guide cabinet also includes a second exhaust component 42. The second vertical plate 32 is provided with a first through hole 321. The first through hole 321 connects the middle left channel 1021 and the middle right channel 1022. The second exhaust component 42 is located in the first through hole 321. The working principle is as follows: The setting of the second exhaust component 42 diverts the cold air entering the middle right channel 1022 to the middle left channel 1021, effectively cooling the middle part of the second set of cabinets 200 in the height direction, increasing the flow rate of the cold air in the second set of cabinets 200 and improving the cooling effect.

[0025] The air guide cabinet also includes an upper air guide hood 51 and a lower air guide hood 52. The upper air guide hood 51 is located in the upper right channel 1012. The first horizontal plate 21 is provided with a first through hole 211, which connects the upper right channel 1012 and the middle right channel 1022. The lower air guide hood 52 is located in the lower right channel 1032. The lower air guide hood 52 is spaced apart from the first exhaust component 41. The second horizontal plate 22 is provided with a second through hole 221, which connects the lower right channel 1032 and the middle right channel 1022. When the air guide cabinet is close to the external air conditioner 300, the upper air guide hood 51 is installed in the upper right channel 1012 and the lower air guide hood 52 is installed in the lower right channel 1032. This effectively gathers the cold airflow blown out of the air outlet of the air conditioner 300. The cold airflow flowing upward from the air outlet of the air conditioner 300 is gathered by the upper air guide hood 51 and flows to the middle right channel 1022. The cold airflow flowing downward from the air outlet of the air conditioner 300 is gathered by the lower air guide hood 52 and flows to the middle right channel 1022, ensuring that all the cold airflow flows to the middle right channel 1022, reducing the energy consumption of the air conditioner 300 and improving the cooling effect.

[0026] The air guide cabinet also includes a first baffle plate 61, which is located in the middle left channel 1021. The first baffle plate 61 is spaced apart from the second vertical plate 32 and intersects with the second vertical plate 32. When the air guide cabinet is close to the external air conditioner 300, the first baffle plate 61 is installed in the middle left channel 1021 to prevent the cold airflow from the middle right channel 1022 from being diverted to the middle left channel 1021 and directly returning to the air conditioner's return air vent, thus ensuring the direction of the cold airflow.

[0027] By installing a second exhaust fan 42, an upper air guide hood 51, and a lower air guide hood 52 inside the air duct, the cold airflow from the air outlet of the external air conditioner 300 is effectively diverted, ensuring that the cold airflow enters the middle right channel 1022, improving the cooling effect, and increasing the flow rate of the cold airflow in the middle zone. The setting of the first baffle 61 prevents the cold airflow from directly entering the return air vent of the air conditioner, effectively isolating the cold and hot airflows.

[0028] Both the upper air guide hood 51 and the lower air guide hood 52 include an air gathering part 5011, a connecting part 5012, and an air outlet part 5013 connected in sequence. The air gathering part 5011 is slidably connected to the connecting part 5012, and the connecting part 5012 is slidably connected to the air outlet part 5013, so as to meet the needs of OTN equipment of different height specifications for on-site installation. By adjusting the overall height specifications of the air gathering part 5011, the connecting part 5012, and the air outlet part 5013, the upper air guide hood 51 and / or the lower air guide hood 52 can be matched with the corresponding OTN equipment. The air gathering part 5011 gathers the cold air from the air conditioning outlet, so that the cold air flows along the connecting part 5012 to the air outlet part 5013, and finally all flows to the middle right channel 1022.

[0029] The air-gathering part 5011 is provided with a concave arc surface 50111, which is located away from the connecting part 5012. The air-discharging part 5013 is provided with a convex arc surface 50131, which is located away from the connecting part 5012. The concave arc surface 50111 further effectively gathers the cold airflow, allowing the cold airflow to flow through the concave arc surface 50111 to the air-discharging part 5013. The convex arc surface 50131 increases the flow rate of the cold airflow into the middle right channel 1022, ensuring that the cold airflow enters the middle right channel 1022.

[0030] Example 3.

[0031] Please see Figure 3a , Figure 3b and Figure 4aThe air guide cabinet of this utility model is placed between the air conditioner 300 and the second set of cabinets 200. The air conditioner 300, the air guide cabinet and the second set of cabinets 200 are connected in sequence along the X direction. The air conditioner 300 adopts the method of air outlet at the bottom and air return at the middle and top of the return air outlet. The air guide cabinet includes a frame 1, a first horizontal plate 21, a second horizontal plate 22, a first vertical plate 31, a second vertical plate 32 and a first exhaust component 41. The frame 1 is shaped like an opening, and the first horizontal plate 21 and the second horizontal plate 22 are both located inside the frame 1, dividing the frame 1 into an upper section, a middle section and a lower section; The first vertical plate 31 is disposed in the upper region and divides the upper region into an upper left channel 1011 and an upper right channel 1012; The second vertical plate 32 is located in the middle area and divides the middle area into a left-middle channel 1021 and a right-middle channel 1022; The first exhaust component 41 is located in the lower area and divides the lower area into a lower left channel 1031 and a lower right channel 1032.

[0032] The air guide cabinet also includes a first baffle plate 61 and a second baffle plate 62. The first baffle plate 61 is located in the middle right passage 1022 and is connected to the frame 1, the first horizontal plate 21 and the second horizontal plate 22 respectively. The second baffle plate 62 is located in the upper right passage 1012 and is connected to the frame 1 and the first horizontal plate 21 respectively.

[0033] The working principle is as follows: The air outlet of the external air conditioner 300 corresponds to the lower right channel 1032. The cold air from the air outlet of the air conditioner 300 flows along the X direction through the lower right channel 1032. The cold air cools the server in the first set of cabinets 100 and the second set of cabinets 200. The hot air generated during the operation of the server flows upward. The hot air returns to the return air vent of the air conditioner 300 through the upper left channel 1011 and the middle left channel 1021. The setting of the first baffle 61 and the second baffle 62 prevents the cold air in the middle and upper part of the air outlet of the air conditioner 300 from directly entering the middle right channel 1022 and the upper right channel 1012. It ensures that all the cold air from the air conditioner 300 enters the lower right channel 1032 from the lower part of the air outlet. In addition, the setting of the first exhaust component 41 draws the cold air from the lower right channel 1032 to the lower left channel 1031, increasing the flow rate of the cold air in the lower area of ​​the frame 1, reducing the impact of the hot air on the cold air, and improving the cooling effect.

[0034] By installing a first baffle plate 61 and a second baffle plate 62 in the air distribution cabinet, with the first baffle plate 61 located in the middle right channel 1022 and the second baffle plate 62 located in the upper right channel 1012, the cold airflow is prevented from flowing directly to the middle right channel 1022 and the upper right channel 1012, and the cold airflow is ensured to flow along the lower right channel 1032 to the second set of cabinets 200 and the first set of cabinets 100, thus effectively guiding the cold airflow.

[0035] The air duct also includes a third baffle plate 63, which is located in the lower left channel 1031. The third baffle plate 63 is connected to the frame 1 and the second horizontal plate 22 respectively. The setting of the third baffle plate 63 prevents the cold airflow in the lower left channel 1031 from directly entering the air return vent of the air conditioner, effectively isolates the cold and hot airflows, effectively guides the flow direction of the cold airflow, and improves the cooling effect.

[0036] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
