Description

Technical Field

[0001] This invention relates to the field of data center cooling technology, specifically to a data center cold aisle with an evaporative condensation structure. Background Technology

[0002] Cold aisle layouts are a design strategy for optimizing airflow and reducing energy consumption in data centers. They improve thermal efficiency and energy utilization by isolating the flow paths of cold and hot air. In traditional data center layouts, cold air is supplied to the equipment behind the racks through floor aisles in front of the racks, creating a hot aisle behind the equipment before being exhausted. This layout easily leads to the mixing of hot and cold air, causing short-circuiting, energy waste, and hotspots. In a cold aisle layout, a closed aisle, called a cold aisle, is formed in front of the racks. The cold aisle contains only cold air, ensuring an effective supply of cold air to the equipment's air inlets and preventing the mixing of hot and cold air. Simultaneously, a hot aisle is formed behind the racks to collect the hot air exhausted from the equipment. However, existing data center cold aisle layouts still have some problems and cannot meet usage requirements.

[0003] Because existing data centers have long cold aisle lengths, data centers closer to the inlet will experience better cooling during the cooling airflow process, while those farther away will experience poorer cooling. This difference in cooling performance will result in differences in the lifespan of the data centers and will hinder synchronized maintenance. Summary of the Invention

[0004] The purpose of this invention is to provide a data center cold aisle with an evaporative condensation structure to solve the problems mentioned in the background art.

[0005] To address the aforementioned technical problems, this invention provides the following technical solution: a data center cold aisle with an evaporative condensation structure, comprising an input component, a cooling component, a diffusion component, an exhaust component, array mounting cabinets, and an arrangement channel. One end of the input component is connected to external air, and the other end is connected to the cooling component. The end of the cooling component furthest from the input component is connected to the diffusion component. The diffusion component is positioned above the center of the arrangement channel and is internally connected to the arrangement channel. Two sets of array mounting cabinets are provided, each set positioned on one side of the arrangement channel. The data center is located inside the array mounting cabinets, which are connected to the exhaust component. The exhaust component is securely connected to both sides of the arrangement channel. The input component draws external air into the cooling component, which cools the air to form cold air. This cold air is then fed into the diffusion component and evenly dispersed throughout the arrangement channel. The cold air diffuses from the center of the arrangement channel into each array mounting cabinet. The hot air generated by the array mounting cabinets is concentrated and transported from the rear to the exhaust component, which then outputs the hot air.

[0006] Furthermore, the input components include an air inlet, a filter, a fan, and a delivery pipe. The air inlet, filter, and fan are positioned above the arrangement channel. The air inlet is connected to the outside air. One end of the delivery pipe is securely connected to the air inlet, and the other end is connected to the cooling component. The filter and fan are connected in series on the delivery pipe, with the filter positioned closer to the air inlet and the fan positioned closer to the cooling component. External airflow enters the air inlet under the action of the fan, flows through the delivery pipe, is filtered by the filter, and is then input into the cooling component.

[0007] Furthermore, a guide cone is installed inside the air inlet. One end of the guide cone is tapered, and the other end is flat. The guide cone is securely connected to the side wall of the air inlet. The tapered surface of the guide cone faces the side of the air inlet away from the delivery pipe. Exhaust holes are provided on the side wall of the air inlet, evenly distributed around the tapered surface of the guide cone. Multiple inclined holes are provided inside the guide cone. One end of each inclined hole connects to the tapered surface of the guide cone, and the other end connects to the flat side of the guide cone. The side of the inclined hole closest to the guide cone is inclined towards the tip of the guide cone. Multiple inclined holes are provided, evenly distributed around the center of the guide cone. Airflow is drawn into the delivery pipe through each inclined hole, and the external airflow, guided by the inclined holes, tends to diffuse outwards along the tip of the guide cone. The guide cone of this invention guides the airflow, causing the airflow mixed with large impurities to generate an initial velocity along the guide cone when it comes into contact with its surface. During this sliding process, the airflow enters the various inclined holes, while the large impurities are thrown towards the edge of the guide cone due to their inertia. At the edge of the guide cone, the large impurities are discharged to the outside through the discharge holes. This design reduces the workload of the filter on large impurities and avoids clogging of the air inlet, greatly improving airflow smoothness.

[0008] Furthermore, the cooling assembly includes an evaporator, a condenser, a heat absorption chamber, a heat dissipation chamber, a distribution box, a setting box, and an output pipe. The setting box is securely connected to the top of the arrangement channel. The distribution box is located on both sides of the setting box, and a partition plate is provided in the middle of the setting box. The setting box is divided into a heat absorption chamber and a heat dissipation chamber. The evaporator is located inside the heat absorption chamber, and the condenser is located in the heat dissipation chamber. Both ends of the evaporator and condenser are connected to the distribution box, and the air inlet is connected to the distribution box. One end of the output pipe is connected to the evaporator, and the other end of the output pipe is connected to the diffusion assembly. Evaporator and condenser are conventional technologies in this field, and their specific structures are not described. The delivery pipe delivers external airflow to the distribution box, which in turn inputs the external airflow into the heat absorption chamber. Liquid refrigerant is delivered by the distribution box to the evaporator, where it evaporates from liquid to gas, absorbing heat from the external airflow. The refrigerant is then delivered from the other side of the distribution box to the condenser. The distribution box inputs a cooling medium into the heat dissipation chamber to condense the refrigerant. The condensed refrigerant is then returned to the evaporator, and the cooled air is output from the output pipe. The distribution and delivery structure inside the distribution box is a conventional technology in this field, and its specific structure is not described.

[0009] Furthermore, the diffusion assembly includes a diffusion box, an inlet, an outlet, an annular chamber, and an air supply unit. The diffusion box is securely connected to the distribution channel at its midpoint. Two annular chambers are symmetrically arranged about the midpoint of the diffusion box. Two air supply units are also provided, each located inside an annular chamber. The inlet is located at the top of the annular chamber, with one end connected to the outlet pipe and the other end connected to the interior of the annular chamber. The outlet is located on the side of the annular chamber, with one end connected to the distribution channel and the other end connected to the interior of the annular chamber. Cooling airflow enters the annular chamber from the inlet and converges. The air supply unit delivers the cooling airflow, distributing it evenly throughout the wide airflow channel and simultaneously outputting it from the outlet to various data centers.

[0010] Furthermore, the air supply unit includes an annular conveyor belt, a partition plate, a lifting rod, and an adjusting component. The annular conveyor belt and the annular bin are fastened together, forming an equally spaced annular channel between the surface of the annular conveyor belt and the annular bin. The partition plate is fastened to the surface of the annular conveyor belt, and multiple partition plates are provided, which are evenly distributed around the surface of the annular conveyor belt. The lifting rod is fastened to the partition plate, one end of the adjusting component is fastened to the partition plate, and the other end of the adjusting component is slidably connected to the surface of the annular conveyor belt. The air delivery unit of this invention drives the isolation plate to rotate via an annular conveyor belt, forming sealed areas in segments inside the annular chamber. When rotating to the inlet position, the inlet pushes the cooling airflow into this sealed area, compressing the adjusting component. When rotating to the outlet position, the adjusting component opens up on its own, synchronously outputting the cooling airflow. As the annular conveyor belt continues to rotate, the airflow is continuously pushed out synchronously by the adjusting component. This structure provides a diffusion buffer for the cooling airflow in a relatively wide output space, but does not significantly expand the installation space. Furthermore, by using the adjusting component to concentrate and synchronously push out the airflow inside the output space, it greatly improves the average cooling effect of each data center.

[0011] Furthermore, the adjustment components include a folding bladder, a surrounding plate, a pull rope, and a torsion spring. One end of the folding bladder is securely connected to the isolation plate, and the other end is securely connected to the surrounding plate. The surrounding plate is slidably connected to the surface of the annular conveyor belt. The torsion spring is located inside the isolation plate. One end of the pull rope is securely connected to the surrounding plate, and the other end is securely connected to the torsion spring. The torsion spring automatically winds up and tightens the pull rope. The torsion spring is a conventional technology in this field, and its specific structure will not be described. When the cooling airflow first enters from the inlet, the cooling airflow will squeeze the surrounding plate, and the surrounding plate will squeeze the folding bladder. The folding bladder has an independent airflow channel and external communication, and does not mix with the airflow inside the sealed area formed between the two surrounding plates. The folding bladder will pull out the pull rope. This part of the cooling airflow moves with the operation of the annular conveyor belt. When it reaches the outlet position, the cooling airflow obtains an outlet channel. The pull rope will pull the folding bladder to expand. After the folding bladder expands, it fills the empty area caused by the cooling airflow output. The cooling airflow is pushed out by the surrounding plate, and each data center obtains an equal amount of cooling airflow.

[0012] Furthermore, the exhaust assembly includes a connecting bend, a central chamber, and an exhaust plate. One end of the connecting bend is securely connected to the array mounting cabinet, and the other end is securely connected to the central chamber. The central chamber is securely connected to the inner wall of the arrangement channel, and the exhaust plate is securely connected to the outer wall of the arrangement channel. The central chamber and the exhaust plate are connected. Heat generated during data center operation is collected in the central chamber via the connecting bend and then discharged by the exhaust plate. The exhaust plate is a conventional technique in this field, and its specific structure is not described.

[0013] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: The guide cone of this invention guides the airflow, causing the airflow mixed with large impurities to generate an initial velocity along the guide cone when it contacts its surface. During this sliding process, the airflow enters the various inclined holes, while the large impurities are thrown towards the edge of the guide cone due to their inertia. At the edge of the guide cone, the large impurities are discharged to the outside through the discharge holes. This design reduces the workload of the filter on large impurities and avoids blockage of the air inlet, greatly improving airflow smoothness. The air delivery unit of this invention drives the isolation plate to rotate via an annular conveyor belt, forming sealed areas in segments inside the annular chamber. When rotating to the inlet position, the inlet pushes the cooling airflow into this sealed area, compressing the adjusting component. When rotating to the outlet position, the adjusting component opens up on its own, synchronously outputting the cooling airflow. As the annular conveyor belt continues to rotate, the airflow is continuously pushed out synchronously by the adjusting component. This structure provides a diffusion buffer for the cooling airflow in a relatively wide output space, but does not significantly expand the installation space. Furthermore, by using the adjusting component to concentrate and synchronously push out the airflow inside the output space, it greatly improves the average cooling effect of each data center.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1-3 As shown, a data center cold aisle with an evaporative condensation structure includes an input component 1, a cooling component 2, a diffusion component 3, an exhaust component 4, array mounting cabinets 5, and an arrangement channel 6. One end of the input component 1 is connected to the outside air, and the other end is connected to the cooling component 2. The end of the cooling component 2 away from the input component 1 is connected to the diffusion component 3. The diffusion component 3 is positioned above the center of the arrangement channel 6 and is internally connected to the arrangement channel 6. Two sets of array mounting cabinets 5 are provided, respectively positioned on both sides of the arrangement channel 6. The data center is located inside the array mounting cabinets 5. The array mounting cabinets 5 are connected to the exhaust component 4, and the exhaust component 4 is securely connected to both sides of the arrangement channel 6. The input component 1 inputs outside air into the cooling component 2, which cools the air to form cold air. The cold air is then sent into the diffusion component 3 and evenly dispersed throughout the middle of the arrangement channel 6. The cold air diffuses from the middle of the arrangement channel 6 into each array mounting cabinet 5. The hot air generated by the array mounting cabinets 5 is concentrated and transported from the rear to the exhaust component 4, which then outputs the hot air.

[0026] like Figure 4As shown, the input component 1 includes an air inlet 11, a filter 12, a fan 13, and a delivery pipe 14. The air inlet 11, filter 12, and fan 13 are arranged on the upper side of the arrangement channel 7. The air inlet 11 is connected to the outside air. One end of the delivery pipe 14 is fastened to the air inlet 11, and the other end of the delivery pipe 14 is connected to the cooling component 2. The filter 12 and fan 13 are connected in series on the delivery pipe 14. The filter 12 is located on the side closer to the air inlet 11, and the fan 13 is located on the side closer to the cooling component 2. The outside airflow enters the air inlet 11 under the action of the fan 13, flows through the delivery pipe 14, is filtered by the filter 12, and is input into the cooling component 2.

[0027] like Figure 4 , Figure 5 As shown, a guide cone 111 is provided inside the air inlet 11. One end of the guide cone 111 is a conical surface, and the other end is a flat surface. The guide cone 111 is fastened to the side wall of the air inlet 11. The conical surface of the guide cone 111 faces the side of the air inlet 11 away from the delivery pipe 14. An exhaust hole 112 is provided on the side wall of the air inlet 11. The exhaust holes 112 are evenly distributed around the conical surface of the guide cone 111. Multiple inclined holes 113 are provided inside the guide cone 111. One end of the inclined hole 113 is connected to the conical surface of the guide cone 111, and the other end of the inclined hole 113 is connected to the flat side of the guide cone 111. The side of the inclined hole 113 near the guide cone 111 is inclined towards the tip of the guide cone 111. Multiple inclined holes 113 are provided and are evenly distributed around the center of the guide cone 111. Airflow is drawn into the delivery pipe 14 through the inclined holes 113. Guided by the inclined holes 113, the external airflow tends to diffuse outward along the tip of the guide cone 111. The guide cone 111 of this invention guides the flow of air, causing the airflow mixed with large impurities to generate an initial velocity along the guide cone 111 when it contacts its surface. During this sliding process, the airflow enters the inclined holes 113, while the large impurities are thrown towards the edge of the guide cone 111 due to inertia. At the edge of the guide cone 111, the large impurities are discharged to the outside through the discharge hole 112. This design reduces the workload of the filter 12 on large impurities and avoids clogging of the air inlet 11, greatly improving airflow smoothness.

[0028] like Figure 6As shown, the cooling assembly 2 includes an evaporator 21, a condenser 22, a heat absorption chamber 23, a heat dissipation chamber 24, a distribution box 25, a setting box 26, and an output pipe 27. The setting box 26 is fastened to the top of the arrangement channel 6. The distribution box 25 is set on both sides of the setting box 26, and a partition plate is set in the middle of the setting box 26. The setting box 26 is divided into a heat absorption chamber 23 and a heat dissipation chamber 24. The evaporator 21 is set inside the heat absorption chamber 23, and the condenser 22 is set in the heat dissipation chamber 24. The two ends of the evaporator 21 and the condenser 22 are respectively connected to the distribution box 25. The air inlet 11 is connected to the distribution box. One end of the output pipe 27 is connected to the evaporator 21, and the other end of the output pipe 27 is connected to the diffusion assembly 3. Evaporator 21 and condenser 22 are conventional technologies in this field, and their specific structures are not described. Delivery pipe 14 delivers external airflow to distribution box 25, and distribution box 25 inputs external airflow into heat absorption chamber 23. Liquid refrigerant is delivered by distribution box 25 to evaporator 21, where it evaporates from liquid to gas, absorbing heat from the external airflow. The refrigerant is then delivered from distribution box 25 on the other side to condenser 22. Distribution box 25 inputs cooling medium into heat dissipation chamber 24 to condense the refrigerant. The condensed refrigerant is then sent back to evaporator 21, and the cooled air is output from output pipe 27. The distribution and delivery structure inside distribution box 25 is a conventional technology in this field, and its specific structure is not described.

[0029] like Figure 7 As shown, the diffusion assembly 3 includes a diffusion box 31, an inlet 32, an outlet 33, an annular chamber 34, and an air supply unit 35. The diffusion box 31 is securely connected to the arrangement channel 6 at the middle position. Two annular chambers 34 are symmetrically arranged about the middle position of the diffusion box 31. Two air supply units 35 are provided, each located inside an annular chamber 34. The inlet 32 ​​is located at the top of the annular chamber 34, with one end connected to the outlet pipe 27 and the other end connected to the interior of the annular chamber 34. The outlet 33 is located on the side of the annular chamber 34, with one end connected to the arrangement channel 6 and the other end connected to the interior of the annular chamber 34. Cooling airflow enters the annular chamber 34 from the inlet 32 ​​and converges. The air supply unit 35 delivers the cooling airflow, distributing it evenly throughout the wide airflow channel and simultaneously outputting it from the outlet 33 to various data centers.

[0030] like Figure 7 , Figure 8As shown, the air supply unit 35 includes an annular conveyor belt 351, a partition plate 352, a lifting rod 353, and an adjusting component 354. The annular conveyor belt 351 and the annular chamber 34 are fastened together, and an equally spaced annular channel is formed between the belt surface of the annular conveyor belt 351 and the annular chamber 34. The partition plate 352 is fastened to the belt surface of the annular conveyor belt 351. Multiple partition plates 352 are provided and are evenly distributed around the belt surface of the annular conveyor belt 351. The lifting rod 353 is fastened to the partition plate 352. One end of the adjusting component 354 is fastened to the partition plate 352, and the other end of the adjusting component 354 is slidably connected to the belt surface of the annular conveyor belt 351. The air supply unit 35 of the present invention drives the isolation plate 352 to rotate via the annular conveyor belt 351, forming a series of sealed areas inside the annular chamber 34. When rotating to the inlet 32 ​​position, the inlet 32 ​​pushes the cooling airflow into this sealed area, and the adjusting component 354 is compressed. When rotating to the outlet 33 position, the adjusting component 354 opens up on its own, and the cooling airflow is output synchronously. As the annular conveyor belt continues to rotate, the airflow is continuously pushed out synchronously by the adjusting component. This structure provides a diffusion buffer for the cooling airflow in a relatively wide output space, but does not significantly expand the installation space. Furthermore, by using the adjusting component 354 to concentrate and synchronously push out the airflow inside the output space, the average cooling effect of each data center is greatly improved.

[0031] like Figure 7 , Figure 8 As shown, the adjusting component 354 includes a folding bag 3541, a surrounding plate 3542, a pull rope 3543, and a torsion spring. One end of the folding bag 3541 is fastened to the isolation plate 352, and the other end of the folding bag 3541 is fastened to the surrounding plate 3542. The surrounding plate 3542 is slidably connected to the surface of the annular conveyor belt 351. The torsion spring is disposed inside the isolation plate 352. One end of the pull rope 3543 is fastened to the surrounding plate 3542, and the other end of the pull rope 3543 is fastened to the torsion spring. The torsion spring automatically winds up and tightens the pull rope 3543. The torsion spring is a conventional technology in this field, and its specific structure will not be described. When the cooling airflow is first introduced from the inlet 32, the cooling airflow will squeeze the surrounding plate 3542, and the surrounding plate 3542 will squeeze the folded bladder 3541. The folded bladder 3541 is provided with an independent airflow channel and external communication, and does not mix with the airflow inside the sealed area formed between the two surrounding plates 3542. The folded bladder 3541 will pull out the pull rope 3543. This part of the cooling airflow moves with the operation of the annular conveyor belt 351. When it moves to the outlet 33, the cooling airflow obtains an output channel. The pull rope 3543 will pull the folded bladder 3541 to expand. After the folded bladder 3541 expands, it fills the empty area caused by the cooling airflow output. The cooling airflow is pushed out by the surrounding plate, and each data center obtains an equal amount of cooling airflow.

[0032] like Figure 1As shown, the discharge assembly 4 includes a connecting bend 41, a central chamber 42, and a discharge plate 43. One end of the connecting bend 41 is securely connected to the array mounting cabinet 5, and the other end is securely connected to the central chamber 42. The central chamber 42 is securely connected to the inner wall of the arrangement channel 6, and the discharge plate 43 is securely connected to the outer wall of the arrangement channel 6. The central chamber 42 and the discharge plate 43 are connected. The heat generated during the operation of the data center is collected in the central chamber 42 through the connecting bend 41 and then discharged by the discharge plate 43. The discharge plate 43 is a conventional technical means in this field, and its specific structure is not described.

[0033] The working principle of this invention is as follows: External airflow enters the air inlet 11 under the action of the fan 13, flows through the delivery pipe 14, is filtered by the filter 12, and is input into the cooling assembly 2. The delivery pipe 14 delivers the external airflow to the distribution box 25, which in turn inputs the external airflow into the heat absorption chamber 23. Liquid refrigerant is delivered by the distribution box 25 to the evaporator 21, where it evaporates from liquid to gas, absorbing heat from the external airflow. The refrigerant is then delivered from the other side of the distribution box 25 to the condenser 22, where the distribution box 25 inputs a cooling medium into the heat dissipation chamber 24 to condense the refrigerant. The condensed refrigerant is then returned to the evaporator 21, and the cooled air is output from the output pipe 27. The cooling airflow enters the annular chamber 34 from the inlet 32 ​​and is collected. The air supply unit 35 delivers the cooling airflow, distributing it evenly throughout the wide airflow channel and simultaneously outputting it from the outlet 33 to various data centers. The heat generated during the operation of the data center is collected in the central chamber 42 through the connecting bend 41 and then discharged through the discharge plate 43.
