[0032] As an aspect of the embodiments of the present application, a server cabinet is provided. As shown in the drawings, Figures 1 to 3 The server cabinet includes a cabinet body 1, a partition plate 2, a heat dissipation mechanism 3, a support plate 5, and a driving mechanism 4. The cabinet body 1 forms an accommodating space inside, and the partition plate 2 is arranged in the cabinet body 1 along the height direction, which divides the accommodating space into an installation space and a heat dissipation space in the width direction. The heat dissipation mechanism 3 is at least partially arranged in the heat dissipation space. The support plate 5 is arranged in the installation space, and a cavity is formed inside the support plate 5, which is in communication with the heat dissipation space. The upper plate of the support plate 5 forms a plurality of ventilation holes 51, and a server 9 is arranged on the upper plate. The driving mechanism 4 is adapted to discharge the first air after the server 9 is cooled to the heat dissipation space, so that the first air exchanges heat with the heat dissipation mechanism 3 to form second air with lower temperature, and then the second air is discharged into the cavity to cool the server 9 through the plurality of ventilation holes 51.

[0033] According to the server cabinet of the embodiments of the present application, the cabinet body 1 is divided into the installation space and the heat dissipation space by the partition plate 2, so that the server 9 can be installed in the closed installation space to avoid dust accumulation caused by the exposed surface of the server 9. The driving mechanism 4 forms air circulation, and the first air (hot air) after cooling the server 9 is discharged to the heat dissipation space, so that the first air exchanges heat with the heat dissipation mechanism 3 in the heat dissipation space to form second air (cold air) with lower temperature, and then the second air returns to the installation space to cool the server 9, forming a complete closed-loop cooling system. Compared with simply introducing external cold air or using a traditional air conditioner, the cold energy can be more effectively utilized, the energy consumption is reduced, the uniform distribution of temperature in the installation space can be maintained, the local overheating phenomenon can be avoided, and the stability and reliability of the server 9 during long-time operation can be improved.

[0034] According to the embodiments of the present application, the server 9 can include a database server, a file server, an application server, etc. In other embodiments, the support plate 5 can be provided with a processor or other components of the server.

[0035] As Figure 1 , Figure 2 and Figure 3As shown, the cabinet body 1 comprises a top wall 14, a bottom wall 15 and two side walls 13 connected between the top wall 14 and the bottom wall 15, the two side walls 13 are arranged along the length direction. The cabinet body 1 further comprises a cabinet door 12 and a back wall 11 facing the cabinet door 12 in the width direction. The bottom wall 15, the side walls 13, the top wall 14, the back wall 11 and the cabinet door 12 enclose a containing space, the cabinet door 12 is pivotally arranged on the side walls 13 and has a closed state for closing the containing space and an open state for opening the containing space.

[0036] The back wall 11 can be detachably connected with at least one of the side walls 13, for example, through screwing, pivot connection or the like. By detaching the back wall 11 from at least one of the side walls 13, the heat dissipation space can be opened to install or maintain the heat dissipation mechanism 3 located in the heat dissipation space.

[0037] The partition plate 2 is connected (for example, through welding, riveting, screwing or the like) between the two side walls 13 to divide the containing space into an installation space facing the cabinet door 12 and a heat dissipation space separated from the cabinet door 12.

[0038] Figure 4 For Figure 3 The partial enlarged view of the partial exploded view of the server cabinet.

[0039] According to the embodiments of the present application, as shown in Figure 3 and Figure 4 The heat dissipation mechanism 3 comprises a cooling coil 31 and a driving assembly (not shown in the figure). The cooling coil 31 is arranged in the heat dissipation space. The driving assembly is arranged outside the cabinet body 1 and is suitable for driving the cooling liquid to flow into one end of the cooling coil 31, so that the cooling liquid exchanges heat with the first air in the heat dissipation space through the cooling coil 31 and then flows out from the other end of the cooling coil 31.

[0040] In such embodiments, the cooling coil 31 is arranged in the heat dissipation space, so that the heat dissipation space can be in a sealed state and can be isolated from the external dust. The driving assembly arranged outside the cabinet body 1 drives the cooling liquid to flow into one end of the cooling coil 31, so that the cooling liquid exchanges heat with the first air in the heat dissipation space through the cooling coil 31 and then flows out from the other end of the cooling coil 31. The large-area arranged cooling coil 31 provides sufficient heat exchange surface for the heat exchange with the first air, so that the cooling liquid can be in sufficient contact with the hot air in the heat dissipation space, and the heat exchange efficiency is improved.

[0041] The cooling liquid can include any one of water, ethylene glycol solution and the like.

[0042] The driving assembly can include a liquid inlet pipe, a liquid return pipe, a pump body, and a cooling liquid tank. One end of the liquid inlet pipe is in communication with one end of the cooling coil 31, the other end of the liquid inlet pipe is in communication with the liquid outlet end of the pump body, the liquid inlet end of the pump body is in communication with the cooling liquid tank, one end of the liquid return pipe is in communication with the other end of the cooling coil 31, and the other end of the liquid return pipe is in communication with the cooling liquid tank. In this way, the pump body can pump the cooling liquid in the cooling liquid tank to one end of the cooling coil 31 through the liquid inlet pipe, and make the cooling liquid flowing out of the other end of the cooling coil 31 return to the cooling liquid tank through the liquid outlet pipe.

[0043] The driving assembly can further include a heat sink (air-cooled or liquid-cooled, etc.). The heat sink is arranged on the liquid outlet pipe, and the heat sink is used to dissipate heat of the cooling liquid flowing through the heat sink, so as to ensure that the cooling liquid reaches a preset temperature threshold before returning to the cooling liquid tank.

[0044] According to the embodiments of the present application, the first air discharged from the installation space to the heat dissipation space can be configured to flow in from the top of the heat dissipation space, and the second air is discharged from the bottom of the heat dissipation space to the installation space after the cooling coil 31 located in the heat dissipation space dissipates heat of the first air.

[0045] According to the embodiments of the present application, as shown in Figure 3 and Figure 4 The cooling coil 31 includes a plurality of pipe body portions 311 and a bending portion 312. The plurality of pipe body portions 311 extend in the height direction and are arranged side by side in the length direction. The bending portion 312 is connected between adjacent two pipe body portions 311 to communicate the plurality of pipe body portions 311.

[0046] In such embodiments, the plurality of pipe body portions 311 extending in the height direction are arranged side by side in the length direction, and the bending portion 312 connects adjacent pipe body portions 311 to form a continuous channel, forming a three-dimensional heat exchange network, increasing the contact area with the first air in the heat dissipation space. The pipe body portion 311 extends in the height direction to form a heat exchange path matching the natural flow direction of the first air, reducing the air flow resistance, so that the hot air (first air) can flow uniformly through the surface of the cooling coil 31, avoiding air flow dead angle or turbulence phenomenon, and ensuring that the heat of the first air can be uniformly transferred to the cooling liquid.

[0047] In some alternative embodiments, the plurality of pipe body portions 311 extend in the length direction and are arranged side by side in the height direction. The bending portion 312 is connected between adjacent two pipe body portions 311 to communicate the plurality of pipe body portions 311.

[0048] In such an embodiment, the parallel arrangement of the cooling coil 31 in the height direction forms multiple levels of heat exchange surfaces, and when the hot air (first air) flows from top to bottom, the first air can be forced to pass through multiple horizontally stacked tube body portions 311, and compared to the case where the tube body portions 311 extend in the height direction, the residence time of the first air in the area of the cooling coil 31 can be prolonged, so that the heat of the first air can be more fully absorbed by the cooling liquid. At the same time, the hot air with a higher temperature in the upper layer first contacts the upper tube body portions 311 for preliminary cooling, and then continues to flow downward to further exchange heat with the lower tube body portions 311, thereby realizing a stepwise temperature reduction process. This gradual temperature adjustment effectively avoids potential damage to the cooling coil 31 caused by sudden temperature changes, and ensures the stability and reliability of the heat dissipation mechanism 3.

[0049] It should be understood that the embodiments of the present application are not limited thereto, for example, the extension direction of the tube body portions 311 can also be inclined to the height direction.

[0050] As an example, the cooling coil 31 can be held between the partition 2 and the rear wall 11 of the cabinet body 1 by the partition 2 and the rear wall 11. Alternatively, the cooling coil 31 can be connected (e.g., welded) between the top wall 14 and the bottom wall 15 of the cabinet body 1 by the bending portion 312.

[0051] According to the embodiments of the present application, as shown in Figure 3 and Figure 4 , the heat dissipation mechanism 3 further comprises a collection assembly 32 connected to the cooling coil 31 (specifically, the plurality of tube body portions 311), and the collection assembly 32 is adapted to collect condensate water generated during the heat exchange process of the first air with the cooling coil 31.

[0052] When the heat dissipation space and the installation space are closed, if the humidity of the air located in the heat dissipation space is too high, condensate water can be generated on the outer wall of the cooling coil 31 during the heat exchange process. If these condensate waters are not handled in time, they can be discharged from the heat dissipation space to the installation space, or even drip onto the server 9, causing the server 9 to short circuit or corrode.

[0053] The server cabinet provided by the embodiments of the present application can comprehensively and efficiently collect the condensate water generated by the tube body portions 311 during the heat exchange process with the first air by connecting the plurality of tube body portions 311 through the collection assembly 32, so as to ensure that the inside of the heat dissipation space remains dry, so that the server 9 can be in a more suitable working environment, and the safety of the server 9 is ensured, and the server 9 failure and safety hazards caused by accumulated water are avoided.

[0054] According to the embodiments of the present application, as shown in Figure 3 and Figure 4As shown, the collecting assembly 32 comprises a plurality of guide grooves 321 and a guide portion 322. The plurality of guide grooves 321 are respectively sleeved on the plurality of pipe body portions 311, and the slots of the guide grooves 321 are upward, so that the condensed water flowing along the pipe body portions 311 is collected in the guide grooves 321. The guide portion 322 is connected to the plurality of guide grooves 321, and is suitable for collecting the condensed water in the guide grooves 321 and discharging the condensed water out of the cabinet body 1.

[0055] In such an embodiment, the guide grooves 321 are respectively sleeved on the vertically arranged pipe body portions 311, and the condensed water flowing down along the outer wall of the pipe body portions 311 can be naturally collected in the guide grooves 321 by the action of gravity. The guide portion 322 is connected to the plurality of guide grooves 321, forming a complete condensed water collection network, which centrally guides and discharges the condensed water dispersed in the guide grooves 321 out of the cabinet body 1, thereby maintaining a dry environment inside the heat dissipation space.

[0056] In some illustrative embodiments, a plurality of guide grooves 321 can be arranged on each pipe body portion 311 in the height direction, so that the condensed water from each height of the pipe body portion 311 can be captured by the plurality of guide grooves 321, avoiding the condensed water drops from any position.

[0057] In such an embodiment, the opening of the guide groove 321 is upward, and the downward flowing hot air can also form a local turbulent flow upward, slowing down the flow rate of the first air flowing downward, prolonging the contact time between the first air and the pipe body portion 311, so that the first air can fully contact the pipe body portion 311, and the overall heat dissipation performance is improved.

[0058] According to the embodiments of the present application, as shown in Figure 3 and Figure 4 As shown, the guide groove 321 comprises a groove bottom 3211 and a groove wall 3212. The groove bottom 3211 is sleeved on the pipe body portion 311 and extends to the rear wall 11 of the cabinet body 1 facing away from the mounting space, and at least a portion of the groove bottom 3211 and the rear wall 11 form a flow channel in communication with the guide portion 322. The groove wall 3212 is configured in a U-shaped structure extending upward from the groove bottom 3211, and the opening of the U-shaped structure faces the rear wall 11 to cooperate with the groove bottom 3211 to make the condensed water flow through the flow channel and be collected by the guide portion 322.

[0059] In such an embodiment, the groove bottom 3211 is sleeved on the pipe body portion 311 and extends to the rear wall 11 of the cabinet body 1, so that the condensed water collected by the guide groove 321 is guided along the guide groove 321 to flow from the flow channel to the guide portion 322 and be captured by the guide portion 322. The flow channel formed between the groove bottom 3211 and the rear wall 11 enables the condensed water to naturally and smoothly flow to the guide portion 322 under the action of gravity without the need for additional power driving.

[0060] According to the embodiments of the present application, as shown inFigure 4 As shown, the groove bottom 3211 extends downward along the width direction (with the opening of the groove facing the inner side of the rear wall 11 of the cabinet 1), so that the condensed water in the guide groove 321 is accelerated to flow out under the action of gravity. Figure 4 As shown, the right side of the groove bottom 3211 is inclined downward, so that the condensed water in the guide groove 321 is accelerated to flow out under the action of gravity.

[0061] In such an embodiment, the groove bottom 3211 of the guide groove 321 extends downward along the width direction, so that the groove bottom 3211 can guide the condensed water to flow to the flow channel at a low position, reducing the residence time of the condensed water in the guide groove 321, and avoiding the accumulation of condensed water on the groove bottom 3211.

[0062] According to embodiments of the present application, as shown in Figure 3 and Figure 4 The guide portion 322 is configured as a groove-shaped structure with the opening of the groove facing upward, and is arranged below the groove bottom 3211 of the guide groove 321. The guide portion 322 extends obliquely along the length direction, and the rear wall 11 forms the first channel 111 communicating with the guide portion 322. The condensed water from the heat dissipation space is guided by the guide portion 322 and discharged from the first channel 111 to the outside of the cabinet 1.

[0063] According to embodiments of the present application, as shown in Figure 2 , Figure 3 and Figure 4 The collection assembly 32 can further include a collection pipe 34. The collection pipe 34 is in communication with the first channel 111 and is formed on the side (outer side) of the rear wall 11 of the cabinet 1 facing away from the heat dissipation space. The bottom of the collection pipe 34 forms a drain opening 341. The collection pipe 34 is used to collect the condensed water in the guide portion 322 arranged at different height positions, and allows the condensed water to be discharged from the drain opening 341 to the outside of the cabinet 1.

[0064] As an example, as shown in Figure 2 The collection pipe 34 is formed on the outer side of the rear wall 11 of the cabinet 1. The collection pipe 34 can be groove-shaped, with the opening of the groove facing the outer surface of the cabinet 1. The collection pipe 34 is formed with the outer surface of the cabinet 1, and guides the cooling liquid to be discharged from the drain opening 341 of the collection pipe 34.

[0065] According to embodiments of the present application, the heat dissipation mechanism 3 further includes fins 33 arranged on the cooling coil 31, which are suitable for increasing the contact area between the cooling coil 31 and the first air, and accelerating the heat transfer between the cooling coil 31 and the first air.

[0066] As an example, as shown in Figure 4As shown, the groove wall 3212 of the guide groove 321 is configured as a downwardly tapered U-shaped structure. With the downwardly tapered groove wall 3212, the condensed water condensed by the fins 33 can also be collected by the guide groove 321, and the condensed water is naturally compressed during the flow process, the flow rate gradually increases, forming a funnel effect, accelerating the collection of the condensed water to the flow channel, which can improve the collection efficiency of the condensed water, prevent the condensed water from forming droplets on the groove wall 3212. retention or splashing, and ensure the directional flow of the condensed water.

[0067] The fins 33 can be prisms or fins. The fins 33 can be arranged in a spiral array on the outer wall of the pipe body part 311 to lengthen the flow path of the first air, so that the first air can make more sufficient and lasting contact with the surface of the fins 33 when flowing through the pipe body part 311, thereby improving the heat exchange efficiency.

[0068] Figure 5 Figure 2 is a partial perspective view of a server cabinet according to an embodiment of the present application, Figure 6 Figure 3 is a partial perspective view of a tray according to an embodiment of the present application.

[0072] In such an embodiment, the cavity formed in the tray 5, together with the second channel 52 on the side plate, the vent hole 51 of the upper plate, and the third channel 21 on the partition plate 2, constitutes an air flow guiding system, so that the cold air from the heat dissipation space can flow in an orderly manner along a predetermined path, sequentially through the third channel 21, the second channel 52, the cavity of the tray 5, and the vent hole 51, and finally blow to the servers 9 on the tray 5 in a uniformly distributed manner, so as to provide the servers 9 on the tray 5 with directional and uniform cooling air flow, so as to ensure that each part of the server 9 can be fully cooled and local hot spots can be avoided. The cavity in the tray 5 plays a buffering and pressure equalizing role for the flow of the second air, so that the air flow speed and flow rate through each vent hole 51 are more balanced, and the cooling efficiency is improved.

[0073] For example, the number of the tray 5 can include any value among 2, 3, 4, and 5. It should be understood that the embodiments of the present application are not limited thereto.

[0088] According to the embodiments of the present application, as shown in Figure 1 , Figure 7 and Figure 8 , the driving mechanism 4 includes a return pipe 41, a connecting pipe 42 and a driving part 43. The return pipe 41 has a plurality of air inlet ends 411 respectively arranged above a plurality of subspaces, and an air outlet end communicating with the plurality of air inlet ends 411. The first end of the connecting pipe 42 communicates with the upper part of the heat dissipation space, and the driving part 43 communicates the air outlet end and the second end of the connecting pipe 42, and is suitable for driving the first air to flow from the air inlet ends 411 and from the air outlet end to the second end, so as to flow into the heat dissipation space under the guidance of the connecting pipe 42.

[0089] The plurality of air inlet ends 411 of the return pipe 41 are respectively arranged above each subspace, which can effectively capture the hot air (first air) after the server 9 is cooled, and avoid the problem of local hot spots caused by the disordered diffusion of the hot air in the cabinet. The driving part 43 serves as the power core to drive the hot air to flow from the air inlet ends 411 into the return pipe 41, and to be guided by the connecting pipe 42 to return to the heat dissipation space, forming a forced air circulation path, which ensures the stability and controllability of the air circulation. And through the circulation of the first air and the second air, the air in the cabinet 1 is reused, reducing the dependence on external fresh air, reducing the risk of dust, humidity and pollutants invading due to the introduction of external air, and improving the cleanliness and environmental adaptability of the server cabinet.

[0090] As shown in Figure 7 and Figure 8As shown, the driving part 43 comprises a driving motor 431. The driving motor 431 is provided with fins 432 on the outer wall thereof, which are used to provide a contact area of air and the driving motor 431, so that the heat generated by the driving motor 431 can be taken away in time, keeping the driving motor 431 within a working temperature range (e.g. not more than 75℃).

[0091] As shown in Figure 7 and Figure 8 , the driving part 43 further comprises a centrifugal assembly 437. The centrifugal assembly 437 comprises a housing and a vane arranged in the housing. The vane rotates under the driving of the driving motor 431, so that the first air is transported from the return pipe 41 to the connecting pipe 42.

[0092] As shown in Figure 7 and Figure 8 , the centrifugal assembly 437 and the driving motor 431 are further provided with a partition 435, which is sleeved on the periphery of the output shaft of the driving motor 431. The driving part 43 further comprises a fan blade 434, which is arranged between the partition 435 and the output shaft and connected to the output shaft of the driving motor 431. The fan blade 434 is configured to rotate with the output shaft of the driving motor 431 relative to the partition 435 to blow air to the centrifugal assembly 437 and cool the centrifugal assembly 437.

[0093] As shown in Figure 7 and Figure 8 , the driving part 43 further comprises a dispersion frame 433 and a heat conduction plate 436. The dispersion frame 433 is arranged between the partition 435 and the centrifugal assembly 437, and the heat conduction plate 436 is arranged between the dispersion frame 433 and the centrifugal assembly 437. The heat conduction plate 436 is adapted to conduct heat from the centrifugal assembly 437, and the dispersion frame 433 is used to disperse the heat from the heat conduction plate 436, so that the heat is transmitted to the surrounding air through the heat dissipation structure of the dispersion frame 433.

[0094] In such an embodiment, through the arrangement of the dispersion frame 433, the air inside the cabinet 1 is pumped and circulated by the centrifugal assembly 437, and the heat of the centrifugal assembly 437 is transmitted to the dispersion frame 433 through the heat conduction plate 436. The output shaft of the driving motor 431 can drive the fan blade 434 synchronously, which guides the airflow close to the ground to blow upwards. The airflow first cools the driving motor 431 through the fins 432, and then is branched by the dispersion frame 433 to make the air fully contact with the dispersion frame 433, so as to fully cool the centrifugal assembly 437, ensuring the stable operation of the centrifugal assembly 437 and the driving motor 431.
