[0001] This application relates to the field of computer room heat dissipation technology, and in particular to a computer room heat dissipation system. Background Technology

[0002] In the field of communications, a data center is an infrastructure that centrally deploys communication equipment and provides communication services, such as data transmission, signal processing, and network operation.

This equipment generates significant heat during operation, and if not properly cooled, it can lead to equipment malfunctions. Related technologies address this by installing air conditioning in the server room to cool the equipment.

[0004] However, because communication equipment generates a lot of heat when it is working, it requires a large amount of air conditioning cooling capacity, which results in high energy consumption for cooling and increases operating costs. Utility Model Content

[0005] To solve the above-mentioned technical problems, or at least partially solve them, embodiments of this application provide a data center cooling system that can reduce cooling energy consumption and operating costs.

[0006] This application provides a data center heat dissipation system, including a data center and an antenna tower, wherein a cabinet is installed in the data center and equipment is installed in the cabinet; The computer room has a first air inlet that connects to the outside, and the bottom of the side wall of the cabinet is provided with a second air inlet that connects to the first air inlet; the top of the cabinet has an air outlet, and the top of the computer room is provided with a ventilation opening at a position corresponding to the air outlet, and the edge of the air outlet is sealed with the edge of the ventilation opening so that the air outlet and the ventilation opening are connected. The antenna tower is installed on the top of the equipment room and located outside the equipment room; the antenna tower has a hollow ventilation channel, which is vertically arranged. The bottom end of the ventilation channel is connected to the ventilation opening, and the top end of the ventilation channel forms an exhaust vent connected to the outside, so that the hot air in the cabinet is discharged sequentially through the exhaust vent, the ventilation opening and the ventilation channel.

[0007] Optionally, an air regulating component is provided at the second air inlet, which can move relative to the second air inlet to adjust the opening size of the second air inlet.

[0008] Optionally, a temperature sensor is provided at the air outlet, and the temperature sensor is used to detect the air temperature at the air outlet; The computer room is also equipped with a controller, and the temperature sensor and the air conditioning unit are electrically connected to the controller respectively; The air regulating component is rotatably connected to the second air inlet. The controller is used to control the rotation angle of the air regulating component according to the temperature detected by the temperature sensor, so as to adjust the opening size of the second air inlet.

[0009] Optionally, the cabinet contains a plurality of the devices, which are spaced apart along the height of the cabinet; each device has an air inlet side and an air outlet side. In all of the aforementioned devices, at least two adjacent devices are provided with an air guide, with the air inlet side and the air outlet side located on opposite sides of the air guide.

[0010] Optionally, the air guide is a plate-shaped component.

[0011] Optionally, a rainproof component is provided inside the ventilation duct; The rain shield is located above the vent, and there is an exhaust gap between the rain shield and the inner wall of the ventilation channel.

[0012] Optionally, the rain shield is a rain shield plate installed on the inner wall of the ventilation channel. The rain shield plate is inclined downward in the direction from the top to the bottom of the ventilation channel, and the antenna tower is provided with a drainage hole at the position corresponding to the lower end of the rain shield plate.

[0013] Optionally, the computer room cooling system may also include a protective top cover; The protective top cover is located above the exhaust vent and there is a gap between them. The vertical projection of the exhaust vent is located within the area enclosed by the outer contour of the vertical projection of the protective top cover.

[0014] Optionally, in the direction from the top of the computer room toward the direction away from the computer room, the ventilation duct includes a connected tapering guide section and a vertical section; The inner diameter of the tapering guide section gradually decreases along the direction close to the vertical section.

[0015] Optionally, a guide fan is provided at the first air inlet; And / or, an air filter is provided at the first air inlet.

[0016] The computer room cooling system provided in this application embodiment includes a first air inlet connected to the outside in the computer room, a second air inlet connected to the first air inlet at the bottom of the side wall of the server rack inside the computer room, an air outlet at the top of the server rack, and a ventilation opening at the top of the computer room corresponding to the air outlet, with the edges of the air outlet and the ventilation opening sealed together to connect the air outlet and the ventilation opening. Simultaneously, an antenna tower is installed outside the computer room, located at the top of the computer room, and has a vertically arranged hollow ventilation channel. The bottom end of the ventilation channel connects to the ventilation opening at the top of the computer room, i.e., the ventilation channel connects to the air outlet of the server rack, and the top end of the ventilation channel forms an exhaust vent connected to the outside. This allows cool air from the outside to enter the computer room through the first air inlet and then exit through the second air outlet of the server rack. The air enters the cabinet through the second air inlet. Since the second air inlet is located at the bottom of the cabinet and the air outlet is located at the top, the air entering through the second air inlet can carry away the heat from the equipment. Hot air is relatively lighter, and the hot air that carries away the heat from the equipment is promptly discharged through the air outlet located at the top, and then discharged to the outside through the exhaust vent of the ventilation channel. In other words, by improving the cabinet and antenna tower, the antenna tower is made into a chimney-like structure, which allows hot air to be discharged in time. Cool air enters the computer room through the first air inlet under the negative pressure of the computer room, and then enters the cabinet to cool the equipment. The chimney effect creates an airflow effect, which achieves forced ventilation of the computer room. The operating temperature in the computer room can be reduced without energy consumption, achieving the purpose of energy saving and emission reduction, effectively reducing the cooling energy consumption of the computer room and reducing operating costs.

[0017] Moreover, since the ventilation channel is formed on the antenna tower, by improving the antenna tower, the antenna tower can achieve the chimney exhaust effect while meeting the antenna installation requirements, further reducing operating costs. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0021] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to". The concepts of "first," "second," etc., used in this application are only used to distinguish different devices, modules, or units, and are not intended to limit the order of functions performed by these devices, modules, or units or their interdependencies. It should be noted that the modifications "a" or "a plurality of" used in this application are illustrative rather than restrictive, and those skilled in the art should understand that, unless explicitly stated in the context, they should be understood as "one or more".

[0022] A data center is an infrastructure for the centralized deployment of communication equipment and the provision of communication services, such as data transmission, signal processing, and network operation. Data centers contain server racks, and communication equipment is housed within these racks. This equipment generates significant heat during operation; if not properly cooled, it can lead to equipment malfunctions. For example, each kilowatt of power consumption from communication equipment generates 0.8 kilowatts of heat. A standard communication data center (one OLT5800 unit at 600 watts each, six 5GBBU units at 800 watts each, and one SPN980 unit at 1152 watts each), under typical configuration, requires a total energy consumption of 6.552 kilowatts and generates 5.241 kilowatts of heat. If air conditioning were installed in the data center to cool the equipment, a 5-kilowatt cooling capacity would be required, significantly increasing operating costs.

[0023] This application provides a data center cooling system for cooling the data center, which can reduce cooling energy consumption and save operating costs.

[0024] Reference Figures 1 to 8 As shown in the figure, the data center cooling system provided in this application embodiment includes: a data center 1 and an antenna tower 4. The data center 1 contains a server rack 2, and the server rack 2 contains equipment 3.

[0025] The computer room 1 can be a traditional communication computer room, a container computer room, an integrated computer room, etc. For example, when the computer room 1 is a container computer room, a standard 20-foot container can be used: external dimensions 6.058 meters × 2.438 meters × 2.591 meters, internal dimensions 5.898 meters × 2.352 meters × 2.390 meters.

[0026] For example, one or more server racks 2 can be installed in server room 1. Server rack 2 can be installed against a wall, and server rack 2 can be a standard 600×600×2200mm server rack, for example.

[0027] Each rack 2 can house one or more devices 3. Devices 3 can be, for example, wireless devices, home broadband devices, or transmission equipment. Devices 3 generate considerable heat during operation, therefore timely heat dissipation is necessary to ensure their proper functioning.

[0028] It is understood that the antenna 10 can be mounted on the antenna tower 4. For example, the antenna tower 4 has an antenna mast on which the antenna 10 is mounted.

[0029] Reference Figures 1 to 8 As shown, the computer room 1 has a first air inlet 11 that connects to the outside. For example, the first air inlet 11 can be located at the lower part of the side wall of the computer room 1.

[0030] The bottom of the side wall of the cabinet 2 is provided with a second air inlet 21 that communicates with the first air inlet 11. The top of the cabinet 2 has an air outlet 22, and the top of the computer room 1 is provided with a ventilation opening 12 at a position corresponding to the air outlet 22. The edge of the air outlet 22 and the edge of the ventilation opening 12 are sealed together so that the air outlet 22 and the ventilation opening 12 are connected.

[0031] Understandably, outside air can enter the computer room 1 through the first air inlet 11, and then enter the server rack 2 through the second air inlet 21. There, it exchanges heat with the equipment 3, carrying away the heat from the equipment 3, and then exits through the air outlet 22 at the top of the server rack 2. Since hot air is lighter, by placing the second air inlet 21 at the bottom of the side wall of the server rack 2 and the air outlet 22 at the top of the server rack 2, cool air enters from the bottom of the side wall of the server rack 2, thus exchanging heat effectively with the equipment 3. The lighter hot air, having absorbed the heat from the equipment 3, then flows out through the air outlet 22.

[0032] In practice, the server rack 2 can be placed against a wall, and the first air inlet 11 can be placed at the lower part of the side wall of the server room 1 facing the server rack 2. For example, there can be two first air inlets 11, and the size of the first air inlet 11 can be, for example, 0.8 meters × 0.8 meters.

[0033] For example, an annular sealing plate can be installed on the top outer side of the cabinet 2 at the position corresponding to the air outlet 22. The bottom edge of the annular sealing plate is sealed to the air outlet 22, and the top edge of the annular sealing plate is sealed to the edge of the ventilation opening 12. This can effectively ensure that the heat discharged from the air outlet 22 of the cabinet 2 is directly discharged through the ventilation opening 12 at the top of the computer room 1, and will not re-enter the computer room 1, thereby improving the cooling and heat dissipation effect.

[0034] The antenna tower 4 is located on top of the equipment room 1 and outside the equipment room 1. The antenna tower 4 has a hollow ventilation channel 41, which is vertically arranged. The bottom end of the ventilation channel 41 is connected to the vent 12, and the top end of the ventilation channel 41 forms an exhaust vent 410 that is connected to the outside, so that the hot air in the cabinet 2 is discharged sequentially through the exhaust vent 22, the vent 12 and the ventilation channel 41.

[0035] In other words, the antenna tower 4 can be modified to form a hollow ventilation channel 41 with open ends on the antenna tower 4, so that the bottom end of the ventilation channel 41 is connected to the ventilation opening 12 on the top of the equipment room 1, that is, the ventilation channel 41 is connected to the air outlet 22. In this way, the lighter hot air rises and enters the ventilation channel 41 through the air outlet 22 and the ventilation opening 12 in sequence. The vertical setting of the ventilation channel 41 forms a chimney effect, so that the hot air is discharged to the outside of the equipment room 1 through the ventilation channel 41. The chimney effect realizes the forced ventilation of the equipment room 1. The cold air outside enters the equipment room 1 from the first air inlet 11 under the negative pressure of the equipment room 1, thereby realizing the air flow inside and outside the equipment room 1, realizing the heat dissipation of the equipment room 1, reducing the operating temperature inside the equipment room 1 without energy consumption, and reducing cooling energy consumption and operating costs.

[0036] For example, the ventilation opening 12 at the top of the server room 1 can be a large opening, corresponding to the air outlet 22 of all server racks 2. Alternatively, there can be multiple ventilation openings 12 at the top of the server room 1, with each ventilation opening 12 corresponding to one air outlet 2 of a server rack 2. As long as the edge of the air outlet 22 is sealed to the edge of the ventilation opening 12, the hot air exhausted from the air outlet 22 can directly enter the ventilation channel 41 through the ventilation opening 12, preventing the hot air exhausted from the air outlet 22 from re-entering the server room 1.

[0037] In practice, an air filter can be installed at the first air inlet 11 to filter the incoming air, thereby improving the cleanliness of the incoming air and preventing dust, debris, and other contaminants from entering the computer room 1 and causing pollution to the equipment 3 inside the computer room 1. This ensures the normal operation and service life of the equipment 3.

[0038] The computer room cooling system provided in this application embodiment includes a first air inlet 11 connected to the outside on the computer room 1, a second air inlet 21 connected to the first air inlet 11 on the bottom side wall of the cabinet 2 inside the computer room 1, an air outlet 22 on the top of the cabinet 2, and a ventilation opening 12 on the top of the computer room 1 corresponding to the air outlet 22, with the edges of the air outlet 22 and the ventilation opening 12 sealed together to connect the air outlet 22 and the ventilation opening 12. Simultaneously, an antenna tower 4 is installed outside the computer room 1, positioned at the top of the computer room 1, and has a vertically arranged hollow ventilation channel 41. The bottom end of the ventilation channel 41 connects to the ventilation opening 12 on the top of the computer room 1, i.e., the ventilation channel 41 connects to the air outlet 22 of the cabinet 2. The top end of the ventilation channel 41 forms an exhaust vent 410 connected to the outside, allowing cool air from the outside to enter the computer room 1 through the first air inlet 11. The air enters the cabinet 2 through the second air inlet 21. Since the second air inlet 21 is located at the bottom of the cabinet 2 and the air outlet 22 is located at the top of the cabinet 2, the air entering through the second air inlet 21 can carry away the heat of the equipment 3. The hot air is relatively light, and the hot air that carries away the heat of the equipment 3 is discharged in time through the air outlet 22 located at the top, and then discharged to the outside through the exhaust vent 410 of the ventilation channel 41. In other words, by improving the cabinet 2 and the antenna tower 4, the antenna tower 4 is made into a chimney-like structure, so that the hot air can be discharged in time. The cold air enters the computer room 1 through the first air inlet 11 under the negative pressure of the computer room 1, and then enters the cabinet 2 to cool down the equipment 3. The air flow effect is formed through the chimney effect, and forced ventilation is achieved in the computer room 1. The operating temperature in the computer room 1 can be reduced without energy consumption, so as to achieve the purpose of energy saving and emission reduction, effectively reducing the cooling energy consumption of the computer room 1 and reducing operating costs.

[0039] Moreover, since the ventilation channel 41 is formed on the antenna tower 4, by improving the antenna tower 4, the antenna tower 4 can achieve the chimney exhaust effect while meeting the installation requirements of the antenna 10, further reducing operating costs.

[0040] In practice, a battery 13 for power supply is also installed in the computer room 1.

[0041] Combination Figure 1 and Figure 2 As shown, in some embodiments, an air regulating component 5 is provided at the second air inlet 21. The air regulating component 5 can move relative to the second air inlet 21 to adjust the opening size of the second air inlet 21.

[0042] This configuration allows for flexible adjustment of the opening size of the second air inlet 21 according to actual usage, thereby flexibly adjusting the air intake of the cabinet 2. For example, when the temperature of the equipment 3 is too high, the air regulating component 5 can be moved to enlarge the opening of the second air inlet 21, thereby increasing the air intake and improving cooling efficiency; when the temperature of the equipment 3 is too low, the air regulating component 5 can be moved to reduce the opening of the second air inlet 21, thereby reducing the air intake and improving the flexibility of use and the accuracy of cooling.

[0043] Continue to refer to Figure 1 and Figure 2 As shown, in some embodiments, a temperature sensor 6 is provided at the air outlet 22, and the temperature sensor 6 is used to detect the air temperature at the air outlet 22.

[0044] The computer room 1 is also equipped with a controller, and the temperature sensor 6 and the air regulating component 5 are electrically connected to the controller. The air regulating component 5 is rotatably connected to the second air inlet 21. The controller is used to control the rotation angle of the air regulating component 5 according to the temperature detected by the temperature sensor 6, so as to adjust the opening size of the second air inlet 21.

[0045] For example, the air regulating component 5 includes an air deflector, which is rotatably connected to the second air inlet 21.

[0046] The controller detects the air temperature at the air outlet 22 in real time or at certain intervals using the temperature sensor 6. When the temperature is higher than the preset temperature threshold, the controller controls the air regulating component 5 to rotate at a preset angle away from the second air inlet 21, thereby increasing the opening of the second air inlet 21. When the temperature is equal to or lower than the preset temperature threshold, the controller controls the air regulating component 5 to rotate at a preset angle closer to the second air inlet 21, thereby decreasing the opening of the second air inlet 21. This achieves precise temperature control and further protects the equipment.

[0047] The preset temperature threshold and preset angle can be preset according to actual conditions, and this application embodiment does not specifically limit them.

[0048] Of course, in other implementations, the air regulating component 5 can also be moved by translation. For example, the air regulating component 5 can be a telescopic structure. By controlling the extension and retraction of the air regulating component 5, the degree of obstruction of the second air inlet 21 by the air regulating component 5 can be changed, thereby changing the opening size of the second air inlet 21. In addition, the air regulating component 5 can also be other structures such as an air regulating block.

[0049] Reference Figure 1 , Figures 6 to 8 As shown, in some embodiments, the cabinet 2 has multiple devices 3, which are spaced apart along the height of the cabinet 2. Each device 3 has an air inlet side 31 and an air outlet side 32.

[0050] Understandably, the cold air entering the computer room 1 enters the computer cabinet 2 through the second air inlet 21, and then enters the equipment 3 through the air inlet side 31, carrying away the heat of the equipment 3. The hot air is discharged from the air outlet side 32 of the equipment 3, and then discharged from the air outlet 22 at the top of the computer cabinet 2 to the outside of the computer cabinet 2. Finally, it is discharged to the outside of the computer room 1 through the ventilation channel 41, thereby achieving heat dissipation for the equipment 3.

[0051] In some embodiments, among all devices 3, at least two adjacent devices 3 are provided with an air guide 7, with the air inlet side 31 and the air outlet side 32 respectively located on both sides of the air guide 7.

[0052] Reference Figure 7 and Figure 8 As shown, for example, the left side of device 3 is the air inlet side 31, and the right side of device 3 is the air outlet side 32. By setting the air guide 7 between two adjacent devices 3, the air inlet side 31 and the air outlet side 32 of any device 3 are separated by the air guide 7. That is, the hot and cold air ducts of device 3 are separated, thereby avoiding to a certain extent the situation where the hot air discharged from the air outlet side 32 of device 3 re-enters device 3 through the air inlet side 31, thus affecting the heat exchange efficiency of device 3.

[0053] Continue to refer to Figures 6 to 8 As shown, in some embodiments, the air guide 7 is a plate-shaped component. This not only achieves effective isolation between the hot and cold air ducts of the device 3, but also simplifies the structure.

[0054] In practice, for example, the air guide 7 can be connected between the two devices 3 using fasteners.

[0055] In addition, in other implementations, the air guide 7 can also be a non-plate structure, as long as it can separate the hot and cold air ducts of the equipment 3.

[0056] In practical use, if rainwater or dust or other debris accidentally enters the ventilation duct 41 through the exhaust vent 410, the rainwater or debris will enter the server rack 2 through the ventilation vent 12, causing contamination or malfunction of the server rack 2 and equipment 3. (Refer to...) Figure 1 and Figure 3 As shown, in some embodiments, a rain shield 8 is provided inside the ventilation channel 41. The rain shield 8 is located above the ventilation opening 12, and there is an exhaust gap 81 between the rain shield 8 and the inner wall of the ventilation channel 41.

[0057] The rain shield 8 blocks rainwater and debris to a certain extent, preventing them from entering the computer room 1 and affecting the equipment 3. The exhaust gap 81 ensures that the exhaust is not affected.

[0058] Continue to refer to Figure 1 and Figure 3 As shown, in some embodiments, the rain shield 8 is a rain shield plate installed on the inner wall of the ventilation channel 41. The rain shield plate is inclined downward along the direction from the top to the bottom of the ventilation channel, and the antenna tower 4 is provided with a drainage hole 42 at the lower end of the corresponding rain shield plate. The drainage hole 42 is in communication with the external environment.

[0059] If rainwater or other accidental water enters the ventilation duct 41 from the exhaust vent 410, the rainwater will fall onto the rain shield. Since the rain shield is tilted downwards, the rainwater will flow down the rain shield to the drain hole 42, and then be discharged from the drain hole 42 to the outside of the computer room 1. This avoids rainwater accumulating on the rain shield and causing leaks, and ensures the safety of the computer room 1.

[0060] Reference Figure 1 , Figure 4 and Figure 5 As shown, the computer room cooling system also includes a protective top cover 9, which is located above the exhaust vent 410 and has a gap between it and the exhaust vent 410. The vertical projection of the exhaust vent 410 is located within the area enclosed by the outer contour of the vertical projection of the protective top cover 9.

[0061] By setting a protective cover 9, the outer contour dimension of the protective cover 9 is not less than the opening size of the exhaust port 410. The above setting can prevent rainwater, dust and other debris from entering the ventilation channel 41 to a certain extent, ensuring the smoothness of exhaust and effectively protecting the computer room 1 and equipment 3.

[0062] Reference Figure 1 As shown, in some embodiments, in the direction from the top of the computer room 1 toward the direction away from the computer room 1, the ventilation duct 41 includes a connected tapering guide section 411 and a vertical section 412. Along the direction approaching the vertical section 412, the inner diameter of the tapering guide section 411 gradually decreases. Here, the inner diameter is... Figure 1The dimension a in the middle.

[0063] By configuring the ventilation duct 41 to include a tapered guide section 411 and a vertical section 412, the tapered guide section 411 can gather and concentrate hot air, increasing the rate at which hot air flows out, thereby further improving the exhaust efficiency of the entire computer room 1 and thus improving the cooling efficiency.

[0064] In some embodiments, a guide fan 111 can be installed at the first air inlet 11 to better introduce cold air from the external environment into the computer room 1, thereby achieving heat dissipation for the equipment 3 in the cabinet 2.

[0065] For example, the air guide fan 111 can be electrically connected to the controller. When the temperature sensor 6 detects that the air temperature at the air outlet 22 is too high, the controller controls the air guide fan 111 to operate, drawing in cool external air into the machine room 1 for forced ventilation. When the temperature sensor 6 detects that the air temperature at the air outlet 22 is too low, the air guide fan 111 does not operate, and the chimney structure of the ventilation duct 41 is sufficient for cooling. This configuration further improves the flexibility of use and the cooling efficiency.

[0066] For example, the power of the wireless device in cabinet 2 is 800W, the power of the home broadband device is 600W, and the power of the transmission device is 1152W.

[0067] Air volume = Equipment power / P × CP × T, where the equipment power is, for example, 800W; P is the air density, usually taken as 1.2 kg / m³ (under standard conditions); CP is the specific heat capacity of air, approximately 1005 J / (kgK). T is the temperature difference between the second air inlet 21 and the air outlet 22, set at 20K.

[0068] The airflow of the wireless device is approximately 118.8 m³ / hour. 3 / h, the air volume of home broadband equipment is approximately 90m³ / h. 3 / h, the transmission equipment has an air volume of approximately 171m³ / h. 3 / h. Therefore, in order to meet the heat dissipation needs of 1 home broadband device, 6 wireless devices, and 1 transmission device, an exhaust / intake air volume of 1000 m³ / h is required.

[0069] For example, when the height of antenna tower 4 is set to 20 meters, it achieves 1000 m. 3 The required chimney (ventilation duct) cross-sectional area for a given exhaust volume of / h is calculated as follows: Change the exhaust volume Q from m 3 / h converted to m 3 / s: 1000 m 3 / h is approximately equal to 0.278m 3 / s.

[0070] If the airflow velocity V is calculated to be 0.238 m / s, then the cross-sectional area of ​​the chimney is A = Q / V = ​​1.168 square meters.

[0071] In other words, when the antenna tower 4 is 20 meters high, a hollow ventilation channel 41 with an internal area of ​​1.168 square meters is sufficient to meet an exhaust / intake volume of 1000 m³ / h. When the antenna tower 4 is 10 meters high, a hollow ventilation channel 41 with an internal area of ​​1.536 square meters is sufficient to meet an exhaust volume of 1000 m³ / h.

[0072] Compared to using air conditioning to cool the computer room, the embodiments of this application improve the antenna tower 4 and other components by setting them as described above, which can achieve good energy-saving ventilation and save considerable electricity costs.
