Description

Technical Field

[0001] This application relates to the field of air conditioning output technology, and in particular to an air conditioning output regulating device for computer rooms. Background Technology

[0002] In recent years, with the rapid development of IT technology, especially the large-scale application of new technologies such as artificial intelligence and cloud computing, the demand for data center construction and use has increased significantly. Servers and other electronic equipment in data center computer rooms generate a large amount of heat during operation; therefore, maintaining a suitable ambient temperature is crucial to ensuring the normal operation of the equipment and extending its lifespan. For this reason, air conditioning systems are widely used in data centers to provide the necessary cooling.

[0003] Traditional data center air conditioning systems typically have their air outlets located on the floor, with the air conditioning blowing air from bottom to top. Due to the natural upward movement of hot air and downward movement of cold air, the cooling effect of upper-level equipment is usually not as good as that of lower-level equipment. This results in uneven temperature distribution within the computer room, creating hot spots that affect the performance and reliability of the equipment. Utility Model Content

[0018] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0019] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0020] First, let me explain the terms used in this application:

[0021] Data Center: A data center is a building that centrally houses electronic information equipment and provides an operating environment, including main server rooms, auxiliary areas, support areas, and administrative areas. By providing a stable power supply, an efficient cooling system, and robust network connectivity, data centers can support the IT operations and data storage needs of enterprises and organizations.

[0022] Cold air aisle: A channel that directly delivers cool air from an air conditioner to the vicinity of the server racks is called a cold air aisle or air supply channel. A cold air aisle is an airflow design specifically for data centers or server rooms to optimize the distribution of cool air and the cooling efficiency of equipment. By delivering cool air directly to the air inlets of the server racks, cold air aisles effectively improve cooling efficiency and energy efficiency. This design not only ensures that equipment operates at optimal temperatures but also reduces the load on the air conditioning system, thereby reducing energy consumption and operating costs.

[0023] Hot air duct: The duct that sends hot air from near the server rack back to the air conditioner is called a hot air duct or return air duct. Hot air ducts are usually used in conjunction with cold air ducts. Physical barriers or partitions isolate the hot air duct from the cold air duct to ensure that hot air and cold air do not mix, forming an orderly airflow management system to optimize cooling efficiency and energy efficiency.

[0024] Fluid mechanics: The branch of science that studies the laws governing the motion of fluids (including liquids and gases) and their interactions with the surrounding environment. It involves analyzing the behavior of fluids under various conditions, the static and dynamic states of the fluid itself, and the interactions and flow laws when there is relative motion between the fluid and solid boundaries.

[0025] The Conanda effect, also known as the wall adhesion effect or boundary layer adsorption effect, refers to the phenomenon where fluids (such as water or gas) tend to deviate from their original flow direction and continue flowing along the surface of a convex object. When surface friction exists between the fluid and the surface of the object it flows over, the fluid will flow along that surface as long as the curvature of the surface is not too large. By utilizing the Conanda effect, more precise control of fluid flow can be achieved, thereby improving the overall efficiency and performance of the system.

[0026] Coanda surface: A curved surface designed using the Coanda effect, allowing fluid to adhere to and continue flowing over it. Coanda surfaces effectively guide fluid flow, prevent fluid separation, and enable fluid control and guidance, and can be used to optimize nozzle design or fluid delivery systems.

[0027] Bernoulli's principle states that under ideal conditions, for any cross-section within the same flow tube, the sum of the kinetic energy, potential energy, and pressure potential energy of a unit volume of fluid remains constant. A famous corollary of this principle is that, under conditions of constant elevation, the greater the fluid velocity, the lower the pressure. Bernoulli's principle can be used to explain many fluid phenomena and applications, such as the lift of aircraft wings, the working principle of sprayers, and the fluid flow behavior in pipes.

[0028] Viscosity of fluids: When there is relative motion between adjacent particles within a fluid, internal friction is generated at their contact surfaces, hindering this relative motion. This property of fluids is called viscosity.

[0029] The continuity equation in fluid mechanics: The continuity equation in fluid mechanics is a fundamental equation based on the law of conservation of mass, used to describe the conservation of mass in a fluid during flow.

[0030] Figure 1 This is a schematic diagram of the air guide component provided in this application. Figure 4 The schematic diagram of the computer room structure provided in this application is as follows: Figure 1 , Figure 4 As shown, the specific application scenario of this application is a data center computer room. The computer room is equipped with air conditioning. The air conditioning outlet is located at the bottom of the computer room, and the air conditioning return outlet is located at the top of the computer room. The computer room air conditioning outlet adjustment device is connected to the computer room air conditioning outlet to guide the cold air flow to the upper part of the computer room.

[0031] Based on the above scenarios, it can be seen that in existing technologies, air conditioning vents are usually placed on the floor. Due to the natural upward movement of hot air and the natural downward movement of cold air, the cooling effect of equipment on the upper level of the cabinet is generally worse than that of equipment on the lower level. This results in uneven temperature distribution within the computer room, forming hot spots, which in turn affects the performance and reliability of the equipment in the computer room.

[0032] This application provides a computer room air conditioning outlet regulating device, including at least one air guiding component. The air guiding component is provided with an air guiding channel, which is provided with an air guiding channel inlet and an air guiding channel outlet. The air guiding channel inlet is connected to the air conditioning outlet. By using the air guiding component to guide the cold air to flow towards a designated position above, the technical problem that the cooling effect of the upper equipment in the computer room is generally worse than that of the lower equipment is solved.

[0033] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. Exemplary embodiments are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0034] Figure 1 This is a schematic diagram of the air guide component 2 of the air outlet regulating device of the air conditioner 120 in the computer room 1 provided in this application. Figure 2 This is a side view of the air guide component 2 of the air conditioning unit 120 in the computer room 1 provided in this application. Figure 4 This is a structural diagram of the computer room 1 provided in this application.

[0035] like Figure 4 As shown, an air conditioner 120 is installed in the computer room 1, employing a bottom-supply, top-return air circulation system. Specifically, the air conditioner's air outlet 121 is located at the bottom of the computer room 1, while the air conditioner's return air outlet 122 is located at the top. Cool air flows from the bottom to the top of the computer room 1, ensuring temperature control throughout the space. The computer room air conditioner air outlet regulating device provided in this embodiment is applied to the computer room 1 and connected to the air conditioner's air outlet 121.

[0036] like Figure 1 , Figure 2 As shown, the air conditioning unit 120 of the computer room 1 includes at least one air guide component 2. The air guide component 2 is provided with an air guide channel 210. The air guide channel 210 is provided with an air guide channel inlet 211 and an air guide channel outlet 212. The air guide channel inlet 211 is connected to the air conditioning outlet 121. The air guide channel outlet 212 is set towards the upper part of the computer room. The air guide component 2 is used to guide the gas to flow towards the upper part of the computer room 1.

[0037] For example, the bottom of the computer room 1 uses a raised floor, such as an electrostatic floor, forming an airflow channel between the electrostatic floor and the floor of the computer room 1; at the same time, the top of the computer room 1 uses a suspended ceiling, forming an airflow channel between the suspended ceiling and the ceiling of the computer room 1. The air conditioning vent 121 is installed on the electrostatic floor.

[0038] The air conditioning unit 120 for computer room 1 is used in this computer room 1. The air conditioning unit 120 for computer room 1 includes at least one air guide component 2. The air guide component 2 is provided with an air guide channel 210. The air guide channel 210 is provided with an air guide channel inlet 211 and an air guide channel outlet 212. The air guide channel inlet 211 is connected to the air conditioning outlet 121.

[0039] The cool air discharged from the air conditioner 120 first flows through the airflow channel formed between the electrostatic floor and the floor of the computer room 1. The cool air is discharged through the air conditioner outlet 121, enters the air guide duct inlet 211, and then enters the air guide duct 210 through the air guide duct inlet 211. Subsequently, the air guide duct outlet 212 guides the cool air to a designated location in the computer room 1, thereby enhancing the cooling effect of the computer room 1.

[0040] In some embodiments, the air guide component 2 includes a first arc plate 220 and a second arc plate 221, which are arranged opposite to each other and have the same bending direction, forming an air guide channel 210 that is an arc-shaped channel.

[0041] The first arc-shaped plate 220 and the second arc-shaped plate 221 work together to achieve the Coanda effect. Specifically, when cold air flows through the second arc-shaped plate 221, due to the viscosity of the fluid, the cold air carries away some of the surrounding still air. Due to the obstruction effect of the second arc-shaped plate 221, the area where some air has been carried away by the cold air cannot receive sufficient air replenishment, resulting in a decrease in pressure at this location and the formation of a low-pressure area. Due to the pressure imbalance on both sides of the cold air, the cold air is forced towards the second arc-shaped plate 221 until it flows along the second arc-shaped plate 221.

[0042] Through the Coanda surface design, the cold air is smoothly guided to the designated area by the second arc plate 221. Furthermore, the cold air output by the Coanda surface has lower turbulence and a more linear airflow profile, which can reduce energy and velocity loss, thereby enhancing the directional cooling effect of the computer room 1 and balancing and optimizing the overall cooling effect of the computer room 1.

[0043] Furthermore, due to the strong low-pressure effect of the Coanda surface, the pressure difference through Bernoulli's principle can draw in more air and guide it to the designated area of ​​computer room 1, thereby enhancing the cooling effect of the upper part of computer room 1 and improving the uniformity of cooling between the upper and lower parts of computer room 1.

[0044] In some embodiments, the second arc-shaped plate 221 is adjacent to the cabinet 110 in the computer room 1. The end of the second arc-shaped plate 221 away from the air conditioner outlet 121 is bent toward the bottom of the computer room 1 to form a protective part 222, so as to prevent the second arc-shaped plate 221 from being too sharp and causing injury to the maintenance personnel of the computer room 1.

[0045] For example, the air guide component 2 includes a first arc plate 220 and a second arc plate 221. The first arc plate 220 and the second arc plate 221 have the same bending direction and are both bent toward the cabinet 110 adjacent to the second arc plate 221 to form an arc-shaped air guide channel 210.

[0046] The second arc-shaped plate 221 extends from the end opposite to the air conditioner outlet 121 at the air duct outlet 212, forming a Coanda surface. When cold air is ejected through the air duct outlet 212, it flows along this Coanda surface due to the Coanda effect. Furthermore, due to the strong low-pressure effect of the Coanda surface, the air near the Coanda surface is drawn into the vicinity of the output cold air by utilizing the pressure difference of Bernoulli's principle. Due to the viscosity of the fluid, the nearby air is also guided to the designated area of ​​the computer room 1, thereby increasing the cooling effect of the upper part of the computer room 1.

[0047] Furthermore, since the Coanda surface is too sharp and could easily injure maintenance personnel in computer room 1, the Coanda surface formed by the extension of the second arc-shaped plate 221 bends towards the bottom of computer room 1 to form a protective section 222. The protective section 222 has a large deflection angle. The bend can form rounded corners to avoid injury to maintenance personnel. In addition, the large deflection angle of the protective section 222 can prevent the airflow of cold air from being guided away by the protective section 222.

[0048] Furthermore, according to the arrangement of the cabinets 110 in the computer room 1, the air guiding component 2 may only include a first arc plate 220 and a second arc plate 221. The first arc plate 220 and the second arc plate 221 are connected to the walls of the computer room 1 at both ends in the width extension direction of the computer room 1, and the first arc plate 220 and the second arc plate 221 form an air guiding channel 210 with the walls at both ends.

[0049] Furthermore, according to the arrangement of the cabinets 110 in the computer room 1, the air guide component 2 may also include two side plates. The two side plates are respectively located at both ends of the first arc plate 220 and the second arc plate 221 in the width extension direction of the computer room 1. The two side plates, the first arc plate 220 and the second arc plate 221 together form an air guide channel 210.

[0050] In some embodiments, the area of ​​the air duct inlet 211 is larger than the area of ​​the air duct outlet 212. When cold air passes through a gradually narrowing air duct 210, the air velocity increases based on the continuity equation in fluid mechanics. The higher air velocity can improve the efficiency of heat exchange and enhance the cooling effect.

[0051] Furthermore, according to Bernoulli's principle, an increase in the velocity of cold air leads to a decrease in pressure. This pressure difference makes the direction of cold air flow easier to control and gives the cold air itself a weak low-pressure effect. By utilizing the strong low-pressure effect of the Coanda surface and the weak low-pressure effect of the cold air itself, more nearby air can be drawn towards the output cold air, further enhancing the cooling effect in the upper part of computer room 1.

[0052] For example, the air guide component 2 includes a first arc-shaped plate 220, a second arc-shaped plate 221, and two side plates. The first arc-shaped plate 220 and the second arc-shaped plate 221 bend in the same direction, both bending towards the cabinet 110 adjacent to the second arc-shaped plate 221. The two side plates are respectively located at both ends of the first arc-shaped plate 220 and the second arc-shaped plate 221 in the width extension direction of the computer room 1. The two side plates, the first arc-shaped plate 220, and the second arc-shaped plate 221 together form an arc-shaped air guide channel 210. The area of ​​the air guide channel inlet 211 is larger than the area of ​​the air guide channel outlet 212.

[0053] The second arc-shaped plate 221 extends from the end opposite to the air conditioner outlet 121 at the air duct outlet 212. The extended part forms a Coanda surface, and the extended part bends towards the bottom of the computer room 1 at a large deflection angle to form a protective part 222.

[0054] Cool air is discharged through the air conditioner outlet 121, enters the air guide channel inlet 211, and then enters the air guide channel 210. Subsequently, the cool air is ejected from the air guide channel outlet 212. Because the area of ​​the air guide channel outlet 212 is smaller than that of the air guide channel inlet 211, the cool air passes through a gradually narrowing air guide channel 210, increasing its velocity. This increased velocity leads to a decrease in pressure, resulting in a weak low-pressure effect. The cool air flows across the Coanda surface of the second curved plate 221. Due to the Coanda effect, the pressure at this location decreases, forming a low-pressure zone. Because of the pressure imbalance on both sides of the cool air, it is forced towards the second curved plate 221 until it flows along it. The cool air is smoothly guided to the designated area by the second curved plate 221, exhibiting lower turbulence and a more linear airflow profile. This not only enhances the cooling effect at the designated location of the cabinet 110 but also reduces energy and velocity losses.

[0055] Furthermore, by utilizing the strong low-pressure effect of the Coanda surface and the weak low-pressure effect of the output cold air itself, the cold air near the Coanda surface and the output cold air is drawn into the vicinity of the output cold air based on the pressure difference of Bernoulli's principle. At the same time, by utilizing the viscosity of the fluid, the nearby cold air is guided to the designated area of ​​the machine room 1, thereby enhancing the cooling effect.

[0056] like Figure 3As shown, in some embodiments, the air guiding component 2 further includes multiple baffles 3 disposed at the air guiding channel outlet 212. The baffles 3 are arranged at intervals along the extension direction of the air guiding channel outlet 212, dividing the air guiding channel outlet 212 into multiple independent air outlets. The multiple independent air outlets are arranged according to the position of the cabinet 110, concentrating the cool air into specific areas to ensure that it accurately reaches the target position, thereby achieving directional ventilation. Furthermore, the multiple independent air outlets formed by the multiple baffles 3 can also affect the pressure in local areas by changing the direction and speed of the cool air flow. The baffles 3 can help to straighten the airflow, reduce the generation of turbulence and eddies, thereby reducing pressure loss in the system and increasing the effective pressure of the system.

[0057] In addition, the position and angle of baffle 3 can be adjusted. By adjusting the position or angle of baffle 3, the direction and flow rate of cold air at each air outlet can be changed, further optimizing the flow path of cold air, reducing unnecessary flow resistance, and increasing the effective pressure of the air outlet. Furthermore, the pressure at other air outlets can be increased by closing some of the air outlets formed by baffle 3.

[0058] In some embodiments, multiple air guide components 2 are arranged side by side in the machine room 1.

[0059] For example, multiple air guide components 2 can be arranged side by side along the direction of the extension of the computer room 1; multiple air guide components 2 can also be arranged according to the position of the server rack 110 in the computer room 1, and arranged opposite to the server rack 110.

[0060] In some embodiments, the plurality of air guide components 2 include at least two different heights.

[0061] For example, the air guide component 2 can have three different heights to guide the cool air to the bottom, middle, and top of the cabinet 110, respectively, thereby solving the technical problem of poor cooling effect in the upper part of the cabinet 110. Furthermore, by adjusting the height, curvature, and distance between the air guide component 2 and the cabinet 110, the position of the cool air delivery can be flexibly adjusted. Specifically, the higher the height of the air guide component 2, the higher the cool air delivery position; the greater the curvature of the air guide component 2, the lower the cool air delivery position; and the greater the distance between the air guide component 2 and the cabinet 110, the higher the cool air delivery position.

[0062] like Figure 4 As shown in the illustration, this application embodiment also provides a computer room 1, which includes an air conditioner 120, multiple server racks, and air guide components 2. The air conditioner outlet 121 is located at the bottom of the computer room 1, while the air conditioner return air outlet 122 is located at the top. The air guide channel inlet 211 of the air guide component 2 is connected to the air conditioner outlet 121, and at least one air guide component 2 is provided between every two adjacent server racks 110.

[0063] In some embodiments, each cabinet group includes two rows of cabinets 110, with the side of the two rows of cabinets 110 facing away from each other being the air supply side 140 and the side adjacent to each other being the air return side 130. The air conditioning outlet 121 of the air conditioner 120 is located on the air supply side 140, and the air conditioning return air outlet 122 of the air conditioner 120 is located on the air return side 130.

[0064] For example, each rack group includes two rows of racks 110. The front of the racks 110 is used for air intake, and the back is used for air exhaust. The side of the two rows of racks 110 that is facing away from each other is the supply air side 140, and the side adjacent to each other is the return air side 130. The front of the racks 110 is located on the supply air side 140, and the fronts of the racks 110 in each pair of adjacent rack groups are arranged opposite each other to form a cold air aisle, and the air conditioning outlet 121 is located in the cold air aisle. The back of the racks 110 is located on the return air side 130, and the backs of the two rows of racks 110 in the rack group are adjacent to each other to form a hot air aisle.

[0065] The cabinet 110 and the ceiling are physically isolated. For example, a sealed door is added to the cabinet 110. The sealed door is seamlessly connected to the ceiling and the cabinet 110 to collect hot air and exhaust it through the air conditioner return air vent 122, thereby improving the cooling utilization rate.

[0066] The cold air flows through the cabinet 110 and forms hot air, which is then discharged into the hot air channel formed at the back of the two rows of cabinets 110. Finally, it is discharged through the air conditioner return air vent 122, which makes the airflow and energy flow in the entire computer room 1 smooth, improves the utilization rate of the air conditioner 120, and further improves the cooling effect.

[0067] In some embodiments, the air conditioning outlet 121 is partially connected to the air duct inlet 211 of the air guide component 2. Specifically, some air conditioning outlets 121 inside the computer room 1 are connected to the air guide component 2, and the air guide component 2 guides the cold air to the upper part of the computer room 1; some air conditioning outlets 121 directly deliver cold air to the computer room 1.

[0068] By connecting the air conditioning outlets 121 to the air duct inlet 211 of the air guide component 2, flexible distribution of cool air can be achieved. Unconnected sections can directly supply air to other areas, ensuring the cooling needs of the bottom of the computer room 1 and improving the flexibility and adaptability of the air conditioning system 120. Furthermore, if all air conditioning outlets 121 are connected to the air guide 210, the pressure within the air guide 210 may become too high, affecting airflow efficiency. The partially unconnected sections help reduce this pressure, improving the overall system efficiency. The partially unconnected air conditioning outlets 121 can also serve as backup or redundancy, ensuring sufficient cooling capacity is still provided even if some air guide components 2 malfunction or require maintenance.

[0069] For example, a computer room 1 includes an air conditioner 120, multiple server racks, and a computer room air conditioner air outlet regulating device. The computer room air conditioner air outlet regulating device includes at least one air guide component 2. The air guide component 2 is provided with an air guide channel 210. The air guide channel 210 is provided with an air guide channel inlet 211 and an air guide channel outlet 212.

[0070] The floor of computer room 1 uses a raised floor, such as an electrostatic floor, forming an airflow channel between the electrostatic floor and the floor of computer room 1. Simultaneously, the ceiling of computer room 1 uses a suspended ceiling, forming an airflow channel between the suspended ceiling and the ceiling of computer room 1. Air conditioning vents 121 are located on the electrostatic floor. The air duct inlet 211 is partially connected to the air conditioning vent 121.

[0071] Each rack group consists of two rows of racks 110. The front of the racks 110 is used for air intake, and the back is used for air exhaust. The side of the two rows of racks 110 facing away from each other is the supply air side 140, and the adjacent side is the return air side 130. The front of the racks 110 is located on the supply air side 140. The fronts of the racks 110 in each pair of adjacent rack groups are arranged opposite each other to form a cold air aisle, and the air conditioning outlet 121 is located in the cold air aisle. The back of the racks 110 is located on the return air side 130. The backs of the two rows of racks 110 in the rack group are adjacent, and a sealed door is installed between the racks and the mounting plates to form a hot air aisle.

[0072] At the connection between the air conditioner outlet 121 and the air guide component 2, the cold air discharged from the air conditioner 120 first flows through the airflow channel formed between the electrostatic floor and the floor of the machine room 1. The cold air is discharged through the air conditioner outlet 121, enters the air guide channel inlet 211, and then enters the air guide channel 210. Subsequently, the air guide channel outlet 212 ejects the cold air. Because the area of ​​the air guide channel outlet 212 is smaller than that of the air guide channel inlet 211, the cold air passes through a gradually narrowing air guide channel 210, increasing its velocity. This increased velocity leads to a decrease in pressure, resulting in a weak low-pressure effect. The cold air then flows through the Coanda surface of the second arc-shaped plate 221. Due to the Coanda effect, the pressure at this location decreases, forming a low-pressure area. Due to the uneven pressure on both sides of the cold air, the cold air is forced towards the second arc plate 221 until it flows along the second arc plate 221. The cold air is smoothly guided by the second arc plate 221 to the designated area, thereby enhancing the cooling effect of the upper part of the computer room 1.

[0073] Where the air conditioner outlet 121 is not connected to the air guide component 2, the cold air discharged from the air conditioner 120 passes through the airflow channel formed between the electrostatic floor and the floor of the computer room 1. The cold air is directly discharged through the air conditioner outlet 121, ensuring the cooling needs of the bottom of the computer room 1, improving the overall cooling efficiency of the system, and thus enhancing the overall cooling effect of the computer room.
