Description

[0001] The utility model relates to the technical field of air - conditioning energy conservation and emission reduction, and particularly relates to a directional cooling air - supply device and a cooling system. Background Art

[0002] BBU is the baseband unit equipment of a base station. With the large - scale construction of 5G networks, the scale of the centralized computer room of the BBU of mobile communication base stations has expanded rapidly, and the equipment density in the cabinet has been increasing continuously, resulting in increasingly serious heat - dissipation problems. Traditional cabinet cooling methods include ordinary upper - air - supply air conditioners, lower - air - supply air conditioners combined with floor openings, liquid cooling, etc. Among them, the methods of lower - air - supply air conditioners combined with floor openings and liquid cooling are suitable for large computer rooms and have high requirements for the design and construction of the computer room itself. They are not suitable for the transformation of existing small computer rooms. Moreover, the above - mentioned methods usually adopt a unified air - supply method, which is difficult to achieve precise cooling of specific areas in the cabinet. In addition, the cooling devices in the prior art often have problems such as uneven air supply and low cooling efficiency. These problems lead to poor heat - dissipation effects of the equipment inside the cabinet, which may cause problems such as equipment overheating, performance degradation, and even damage.

[0003] Although the prior art can achieve a certain degree of directional cooling, there are still problems such as uneven cold - air distribution and low energy efficiency. Specifically, common directional cooling air - supply devices also mostly adopt a unified air - supply method. They send cold air into the cabinet through connecting pipes. Although the cooling effect is improved to a certain extent, there are still problems such as uneven air supply and low cold - air utilization efficiency. In addition, when cold air passes through the connecting pipes and horizontal main pipes, due to the limitations of the pipe structure and air - flow characteristics, it is often impossible to achieve uniform distribution, resulting in excessive cold air in some areas and insufficient cold air in some areas.

Specific embodiments

[0034] In order to make the purposes, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] The technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0036] Embodiment 1:

[0037] Please refer to Figure 1 - Figure 2 and Figure 6 , the present utility model provides a technical solution:

[0038] Overall structure

[0039] This embodiment relates to a directional cooling air supply device. Specifically, refer to Figure 1 - Figure 2 , which includes a connecting pipe 1 and a terminal air supply device. One end of the connecting pipe 1 is connected to a refrigeration fan 5 for generating cold air, and the other end is communicated with the terminal air supply device. The connecting pipe 1 horizontally extends along the top wall of the cabinet 4 towards the air inlet side opposite to the cabinet 4. The terminal air supply device includes a fixed-point air supply pipe 3. The fixed-point air supply pipe 3 is located on the air inlet side opposite to the cabinet 4 and extends along the vertical direction of the cabinet 4. The fixed-point air supply pipe 3 includes a plurality of air outlet pipes 31 arranged along the length direction. The plurality of air outlet pipes 31 are used to send cold air into the gap between two BBU units.

[0040] This structure enables the cold air to accurately and evenly blow towards the BBU units inside the cabinet 4, improves the utilization efficiency of the cold air, realizes efficient heat dissipation, has a higher cooling effect and lower energy consumption. At the same time, the structure design of this directional cooling air supply device is simple and practical, which is convenient for production and maintenance.

[0041] According to the size and heat dissipation requirements of the cabinet 4, design appropriate connecting pipe 1 and terminal air supply device. During the actual operation process, according to the heat dissipation situation of the equipment inside the cabinet 4, adjust the structural parameters of the connecting pipe 1 and the terminal air supply device, such as the length and caliber of the connecting pipe, etc., to achieve the best cooling effect and realize the accurate distribution of cold air inside the cabinet 4. At the same time, the connecting pipe 1 and the terminal air supply device can be cleaned and maintained regularly to ensure the normal operation of the system and extend the service life.

[0042] In order to further ensure that the cold air flow can pass through the BBU device to the greatest extent, a wind guiding member can be installed in the gap between two BBU units. The wind guiding member includes a partition. The partition divides the gap between two BBU units into an air inlet guiding chamber and an air outlet guiding chamber along the diagonal, and corresponds the air outlet pipe to the air inlet guiding chamber. The arrangement position and specific structure of the wind guiding member belong to the prior art and will not be elaborated here.

[0043] By arranging air guiding components in the gaps of the BBU device, the cold air blown out from the fixed-point air supply duct 3 enters the cabinet 4 centrally through the air inlet guiding chamber. Under the guidance of the air guiding components, it enters the interior of the device through the air inlets on the side of the BBU device. After cooling the device, the hot air enters the air outlet guiding chamber from the air outlets on the opposite side of the BBU device and is sent out of the cabinet 4. Through the cooperation of the fixed-point air supply duct 3 and the air guiding components, the formation of an effective air flow organization is further fully improved and strengthened, enabling the cold air flow to pass through the BBU device to the greatest extent, avoiding the problem of local overheating of the device caused by the backflow short circuit of the hot air flow inside the cabinet 4, and greatly improving the heat dissipation efficiency of the device;

[0044] Terminal air supply device

[0045] As Figure 1 shown, in this embodiment, the terminal air supply device further includes an air supply adapter 2. The air supply adapter 2 is a bent pipe structure, including a horizontal part and a vertical part. The horizontal part is used to connect with the connecting pipe 1, and the vertical part is used to connect with the fixed-point air supply duct 3. A flow guiding plate is arranged in the fixed-point air supply duct 3. The flow guiding plate extends downward along the vertical direction towards the air outlet side, and the end of the flow guiding plate is connected to the end of the fixed-point air supply duct 3.

[0046] When the cross-section of the fixed-point air supply duct 3 is consistent, the dynamic pressure of the internal air flow gradually decreases along the gas flow direction, and the static pressure gradually increases. By arranging a flow guiding plate in the fixed-point air supply duct 3, the volume of the fixed-point air supply duct 3 can be gradually reduced in the gas flow direction, so as to make up for the difference caused by the gradual increase of the static pressure, thereby ensuring that the air pressure and air speed of each air outlet duct 31 are relatively uniform. At the same time, the arrangement of the flow guiding plate has a good flow guiding effect, making the air flow enter the air outlet duct 31 more smoothly.

[0047] In addition, according to the different layout heights of the BBU device in the cabinet 4, the air supply adapter 2 and the fixed-point air supply duct 3 can be connected through an auxiliary connecting pipe. The auxiliary connecting pipe is composed of a plurality of modular pipe modules connected end to end. According to the layout requirements of different cabinets 4 and internal devices, an appropriate number of pipe modules can be selected to form a connecting pipe to adjust the height of the fixed-point air supply duct 3 to adapt to the layout of the BBU device.

[0048] Connecting pipe structure

[0049] The connecting pipe 1 includes a first pipe 11 and a second pipe 12. Refer to Figure 1 and Figure 6 , the first pipe 11 extends vertically upward from above the refrigeration fan 5, the second pipe 12 is horizontally arranged and is slightly higher than the cabinet 4 in the vertical direction. The first pipe 11 and the second pipe 12 form an "L" shape through a pipe elbow, so that the cold air can smoothly enter the air supply adapter 2 of the terminal air supply device.

[0050] The connecting pipe 1 includes a plurality of modular pipe modules and pipe elbows. Among them, the number of pipe modules can be selected according to the height of the cabinet 4, the layout height of the BBU unit, etc. The plurality of modular pipe modules and pipe elbows are connected end to end through connectors to form connecting pipes 1 of different heights to adapt to the layout requirements of different cabinets 4 and internal devices.

[0051] Since the horizontal space in the computer room is relatively narrow, setting the connecting pipe 1 on the top of the computer room instead of on the ground is conducive to saving space, effectively solving the problem of narrow horizontal space, improving the space utilization rate, facilitating later maintenance and management, reducing the maintenance cost and work difficulty. By optimizing the structure and layout of the connecting pipe 1, a more uniform and efficient air supply effect can be achieved, and the overall operation efficiency of the computer room is improved.

[0052] According to the actual layout and requirements of the computer room, the path and direction of the connecting pipe 1 can be reasonably designed. The connecting pipe 1 can be fixed above the computer room in a suspended or supported manner to ensure the stability and safety of the pipe; at the same time, in order to facilitate maintenance, inspection ports or observation windows can be set at key nodes of the pipe to facilitate maintenance personnel to check and maintain the pipe at any time; in addition, appropriate thermal insulation materials and sound insulation materials can be set on the pipe to reduce energy loss and noise generation.

[0053] The specific operation process can be carried out in the following way: First, determine the specific position and direction of the connecting pipe 1 according to the actual size and layout requirements of the computer room; then, select appropriate materials and connection methods to construct the main structure of the connecting pipe 1. In the design process of the pipe, means such as streamline design or adding flow disturbing elements can be considered to optimize the air supply effect; finally, connect the connecting pipe 1 to the refrigeration fan 5 and carry out necessary debugging and testing to ensure the normal operation of the connecting pipe 1 and the air supply effect meets the expected requirements.

[0054] In this embodiment, a pipe elbow is provided at the connection of the first pipe 11 and the second pipe 12, which has a rounded corner transition. See Figure 6 . The rounded corner transition design can reduce the impact and vortex generation of the fluid at the pipe connection, thereby reducing the fluid resistance and improving the smoothness of the fluid flow. In addition, the rounded corner transition design also has good machinability and assemblability. During the manufacturing process, the rounded corner design makes the connection part of the pipe easier to machine and form, reducing the manufacturing cost. At the same time, during the assembly process, the rounded corner transition can also provide a larger assembly space, making the assembly more convenient and accurate.

[0055] In this embodiment, the directional cooling air supply device may further include a support frame 5, which is fixedly arranged on the top wall of the cabinet 4, and fixes the connecting pipe 1 and the terminal air supply device on the top wall of the cabinet 4, ensuring a more firm and stable connection between the connecting pipe 1 and the terminal air supply device and the cabinet 4, avoiding accidents and losses that may be caused by the shaking or falling off of the connecting pipe 1 or the terminal air supply device, and improving the safety and stability of the entire system.

[0056] Cooling system

[0057] The present invention also relates to a cooling system, including the above-mentioned directional cooling air supply device and the refrigeration fan 5. The cooling system formed by the supporting use of the above-mentioned directional cooling air supply device and the refrigeration fan 5 has the advantages of high cooling efficiency and saving machine room space. Through directional cooling air supply, the key hot spot temperature of the BBU unit can be quickly reduced, improving the overall operation stability. The compact system design makes the machine room space more reasonably utilized. Therefore, this cooling system can achieve efficient and energy-saving cooling of the BBU unit, improving the overall operation efficiency and stability of the machine room.

[0058] In this embodiment, the refrigeration fan 5 is arranged on the floor of the machine room. Refer to Figure 1 , the air outlet of the refrigeration fan 5 is arranged at the top cover of the casing of the refrigeration fan 5. The connecting pipe 1 includes a connecting pipe air inlet 13 and a connecting pipe air outlet 14. The connecting pipe air inlet 13 is connected to the air outlet of the refrigeration fan 5, and the connecting pipe air outlet 14 is connected to the terminal air supply device.

[0059] Arranging the air outlet of the refrigeration fan 5 at the top cover of the casing of the refrigeration fan 5, and connecting the connecting pipe air inlet 13 to the upper surface of the refrigeration fan 5 instead of the bottom of the refrigeration fan 5, avoiding complex connecting pipes on the floor of the machine room, not occupying the maintenance passage, being beneficial to saving space, effectively solving the problem of narrow horizontal space, and improving the space utilization rate; moreover, this design is beneficial to directly introducing cold air from above the refrigeration fan 5 into the terminal air supply device located at the top of the cabinet 4, and finally blowing towards the air inlet side of the cabinet 4 to form a more uniform and efficient air curtain; in addition, this setting can achieve precise control of the cold air flow. Specifically, according to the heat distribution inside the cabinet 4 and the cold air flow characteristics, the position and size of the connecting pipe air outlet 14 can be accurately designed and adjusted to ensure that the cold air can be accurately blown to the area that needs to be cooled. This setting can better adapt to the layout requirements of different cabinets 4 and internal devices, improving the versatility and flexibility of the overall device. For example, in the case of a relatively high cabinet 4, the connecting pipe air outlet 14 can be set higher through different numbers of pipe modules to ensure that the cold air can cover the entire air inlet side of the cabinet 4.

[0060] Embodiment 2:

[0061] Please refer to Figure 3 - Figure 5 , the present utility model provides another technical solution. The difference between the directional cooling air supply device involved in this technical solution and that of the first embodiment lies only in the different structure of the terminal air supply device.

[0062] Other forms of the terminal air supply device

[0063] In this embodiment, a plurality of cabinets 4 are arranged side by side, and a plurality of BBU units are placed horizontally in their respective cabinets 4.

[0064] The terminal air supply device includes an air supply adapter 2. The air supply adapter 2 includes a horizontal main pipe 21 and a horizontal main pipe branch 22. The horizontal main pipe 21 is connected to the connecting pipe 1 and horizontally extends along the top wall of the cabinet 4 towards the back air inlet side of the cabinet 4. Multiple branches are formed at the end of the horizontal main pipe 21, and each branch is connected to a horizontal main pipe branch 22. Each horizontal main pipe branch 22 is respectively connected to a fixed-point air supply pipe 3 for supplying cold air to the multiple cabinets 4.

[0065] Specifically, in this embodiment, the end of the horizontal main pipe 21 is divided into two branches, and the end of the horizontal main pipe 21 is connected to two horizontal main pipe branches 22. A plurality of branch pipes 221 are provided in each horizontal main pipe branch 22, and arc-shaped air distribution plates 222 are provided between adjacent branch pipes 221. The two horizontal main pipe branches 22 respectively correspond to a cabinet 4. Through the fixed-point air supply pipes 3 connected thereto, the correspondence between the cooling air flow and the BBU unit is stronger, and the cooling air flow can contact each BBU unit more directly and evenly, improving the overall cooling effect. During implementation, the length, width, turning diameter change, etc. of each horizontal main pipe branch 22 can be adjusted as needed to ensure that the cooling air flow can directly cover each BBU unit.

[0066] In this embodiment, a plurality of the branch pipes 221 have cross-sectional shapes with similar sizes, improving the uniform distribution of cold air inside the cabinet 3 and avoiding the occurrence of local overheating in the computer room. By precisely controlling the cross-section of the branch pipes 221, it can better adapt to the cooling requirements of different cabinets 3, improving the versatility and flexibility of the device. Specifically, by adjusting the size and shape of the cross-section of the branch pipes 221, the flow direction and flow rate of the cold air can be precisely controlled to better adapt to the cooling requirements inside the cabinet 3.

[0067] In addition, flow guiding vanes are provided at multiple branch positions at the end of the horizontal main pipe 21. The flow guiding vanes can be one, two or more. They are provided at the bending part of the horizontal main pipe 21 and can divide the air duct into multiple air passages at the turning radius of the bending part is too small to reduce resistance.

[0068] It should be noted that the arrangement position of the refrigeration fan 5 in the cooling system is not limited to the floor of the machine room. For example, Figure 7 as shown, the refrigeration fan 5 can also be firmly installed on the top of the machine room using a fixing device. This arrangement not only further reduces the floor area occupied by the refrigeration fan in the machine room, making the space utilization of the machine room more reasonable and efficient, but also significantly improves the cooling efficiency and shortens the distance of the cold air from the generation end to the output end, thereby reducing the energy loss during the transportation of the cold air. In addition, using the fixing device to firmly install the refrigeration fan 5 on the roof of the machine room ensures the stability and reliability of the refrigeration fan 5, and can effectively prevent the refrigeration fan 5 from shaking or shifting due to external factors (such as wind force, vibration, etc.), thus ensuring the continuous and stable cooling of the machine room and enabling it to continuously provide stable and efficient cooling effects for the machine room. Therefore, this setting not only improves the cooling efficiency of the machine room, but also reduces the energy consumption and operation cost, providing a strong guarantee for the long-term stable operation of the machine room.

[0069] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
