[0002] Current cabinets all have fixed nozzles. During the spray cooling process, coolant is sprayed to different cooling areas with the same spray intensity, which cannot guarantee that all areas can be evenly exposed to the coolant. It is also not suitable for situations where different areas of the server system have different cooling requirements.

[0003] When a server's local temperature is high and the cooling intensity needs to be increased, the overall spray intensity needs to be increased, resulting in a waste of resources. When a server's local temperature is low and the cooling intensity needs to be reduced, the spray intensity cannot be directly reduced to take into account the cooling needs of other areas, which also results in a waste of resources.

[0038] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0040] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0041] The length direction and width direction of the cabinet body 1 mentioned in this application document are two mutually perpendicular directions in the cabinet body. When the shape of the cabinet body 1 changes, the length direction and width direction of the cabinet body 1 may change.

[0042] An embodiment of the present application provides a cabinet, including a cabinet body 1, a liquid storage device 2 and a spray device; the cabinet body 1 is used to place heat-generating equipment; the liquid storage device 2 stores coolant inside; one end of the spray device is located in the liquid storage device 2, and the other end sprays coolant toward the heat-generating equipment in the cabinet body 1; the spray device includes a movable spray component and a rotating spray component, and the movable spray component is movably arranged in at least one direction in the cabinet body 1 to adjust the spray position; the spray end of the rotating spray component is rotatable around the central axis.

[0043] The heat generating device in this embodiment can be a server or any other heat generating device that meets the requirements. The specific determination is based on actual conditions and will not be elaborated here. The heat generating devices can be arranged in multiple layers along the height direction within the cabinet body 1. The movable spray assembly and the rotating spray assembly are each provided with a nozzle on the heat generating device at the corresponding layer to dissipate heat from the heat generating devices at different layers.

[0044] In actual use, the heat dissipation area of ​​the heating equipment corresponding to the mobile spray assembly generally has lower heat dissipation requirements, while the heat dissipation area of ​​the heating equipment corresponding to the rotary spray assembly has higher heat dissipation requirements. Based on the heat dissipation requirements of different locations on the heating equipment, the heat dissipation area of ​​the heating equipment can be rationally divided into different areas, so that different heat dissipation areas correspond to mobile spray assemblies or rotary spray assemblies respectively. The number of mobile spray assemblies and rotary spray assemblies can be appropriately adjusted based on the size of the heating equipment and the distribution requirements of different heat dissipation areas.

[0045] The liquid storage device 2 can be arranged on the lower side of the cabinet body 1. During use, the spraying device draws out the coolant in the liquid storage device 2 and sprays it onto the surface of the heating equipment in the cabinet body 1. The sprayed coolant can flow back to the liquid storage device 2 under the action of gravity to realize the recycling of the coolant.

[0046] In this specific embodiment, the same movable spray assembly can be movable in at least one direction, or different movable spray assemblies can be movable in different directions, respectively. The specific embodiment is determined according to actual conditions and will not be described in detail here. During actual use of the rotary spray assembly, since the spray end of the rotary spray assembly rotates around the central axis, the coolant can be evenly sprayed to the corresponding heat dissipation area. In addition, if some of the spray holes of the rotary spray assembly are blocked, the spray end rotates around the central axis, so the coolant can still be evenly sprayed to the corresponding heat dissipation area, without affecting the heat dissipation effect of the heating device.

[0047] In the cabinet provided by this specific embodiment, since the spray device includes a mobile spray assembly and a rotating spray assembly, in actual use, the heat dissipation areas corresponding to the mobile spray assembly and the rotating spray assembly can be reasonably allocated according to the different heat dissipation requirements of different positions of the heating device. Specifically, the rotating spray assembly can be allocated to the heat dissipation area with higher heat dissipation requirements, while the mobile spray assembly can be allocated to the heat dissipation area with lower heat dissipation requirements. In addition, when the temperature of a certain position of the heat dissipation area corresponding to the mobile spray assembly in the heating device increases and the heat dissipation requirement increases, the mobile spray assembly can be controlled to move to the position corresponding to the area, focusing on spraying the area with increased temperature, thereby improving the heat dissipation effect and meeting the heat dissipation requirement. When the temperature of a certain position of the heat dissipation area corresponding to the rotating spray assembly in the heating device increases and the heat dissipation requirement increases, the heat dissipation effect can be improved by increasing the spray flow rate of the rotating spray assembly, thereby meeting the heat dissipation requirement. Therefore, the technical problem of resource waste caused by using the same spray intensity for heating areas of different temperatures in the related art can be solved, and the technical effect of reasonably arranging the spray assemblies for heating areas with different heat dissipation requirements and focusing on cooling the area with higher heat dissipation requirements can be achieved.

[0048] In a specific embodiment, the mobile spray assembly includes a mobile pipeline 8, a plurality of first nozzles 10 and a driving mechanism 9, wherein one end of the mobile pipeline 8 is located in the liquid storage device 2, the other end of the mobile pipeline 8 extends from the liquid storage device 2, and the length direction of the mobile pipeline 8 located in the cabinet body 1 is arranged along the height direction of the cabinet body 1; the plurality of first nozzles 10 are installed in the part of the mobile pipeline 8 located in the cabinet body 1, and the spraying direction of the first nozzle 10 is toward the heating equipment in the cabinet body 1; the driving mechanism 9 is installed in the liquid storage device 2 or the cabinet body 1, and the moving end of the driving mechanism 9 is connected to the mobile spray assembly to drive the mobile spray assembly to adjust the spraying position.

[0049] like Figure 1 As shown, there are multiple first nozzles 10, and the multiple first nozzles 10 are arranged at intervals along the length direction of the movable pipeline 8, so that different first nozzles 10 can correspond to heating devices at different heights in the cabinet body 1, so that different first nozzles 10 can correspond to heating devices at different heights.

[0050] In actual use, when the first nozzle 10 is installed, the installation angle of the first nozzle 10 can be adjusted so that the first nozzle 10 can spray the desired heat dissipation area. When the temperature of a certain location of the heating device increases locally, the driving mechanism 9 drives the movable pipe 8 to move to a position where the first nozzle 10 can spray the area with the increased temperature. The first nozzle 10 then sprays the coolant more specifically on the area with the increased temperature, thereby achieving focused heat dissipation in the area with the increased temperature and meeting the heat dissipation requirements of the heating device when the temperature increases locally.

[0051] In this embodiment, by providing a movable pipeline 8 and a plurality of first nozzles 10, during actual use, the movable pipeline 8 can be moved by the driving mechanism 9 to adjust the spraying position of the first nozzle 10, thereby facilitating the heat dissipation of locations with higher heat dissipation requirements for heat-generating equipment. Furthermore, in this embodiment, multiple first nozzles 10 can be provided in the same movable pipeline 8, and the spraying positions of the multiple first nozzles 10 can be adjusted during the movement of the movable pipeline 8.

[0052] On the basis of the above embodiment, the movable pipeline 8 can be extended in the cabinet body 1 along the length direction of the cabinet body 1, and multiple first nozzles 10 are arranged at intervals in the length direction of the movable pipeline 8. The first nozzles 10 on the same movable pipeline 8 dissipate heat for the heating equipment at the same height position; in the actual setting process, a corresponding movable pipeline 8 can be set for each layer of heating equipment, and any movable pipeline 8 can be moved independently, and the moving direction of the movable pipeline 8 is along the length direction of the movable pipeline 8.

[0053] During actual use, when it is detected that a local area of ​​a heating device on a certain layer in the cabinet body 1 has a higher temperature, the movable pipe 8 corresponding to the heating device can be adjusted to move along its length direction so that the first nozzle 10 can focus on spraying the area with higher temperature in the heating device to meet the heat dissipation requirements when the local temperature of the heating device rises.

[0054] The cabinet in this specific embodiment is provided with different mobile pipelines 8 corresponding to heating devices at different heights. During actual use, the corresponding mobile pipelines 8 can be adjusted for heating devices at different heights to avoid the situation where the first nozzle 10 in the same mobile pipeline 8 cannot take into account heating devices at different heights.

[0055] In a specific embodiment, the driving mechanism 9 includes a mounting frame 91, a driving power member 92, a lead screw 93, a threaded sleeve 94 and a limit member 95; the mounting frame 91 is arranged on the outside of the liquid storage device 2; the driving power member 92 is installed in the mounting frame 91; the lead screw 93 is connected to the output end of the driving power member 92 and is driven to rotate by the driving power member 92; the threaded sleeve 94 is sleeved on the outer periphery of the lead screw 93 and is threadedly matched with the lead screw 93; the threaded sleeve 94 is connected to the moving pipeline 8; and the limit member 95 is arranged at the end of the lead screw 93.

[0056] like Figure 2 、 Figure 3As shown, the mounting frame 91 is fixedly mounted on one side of the liquid storage device 2, and the rear portion of the inner cavity of the mounting frame 91 is fixedly connected to the driving power member 92. The driving power member 92 can be set as a servo motor, which is electrically connected to an external power supply and controlled by the control system 31. The output shaft of the driving power member 92 is fixedly connected to the screw 93 through a coupling. The screw 93 can be set as a reciprocating screw. One end of the reciprocating screw is rotatably connected to the mounting frame 91 through a bearing 282. The surface of the reciprocating screw is slidably connected to a threaded sleeve 94. The surface of the threaded sleeve 94 is fixedly connected to the moving tube on the left side by a fixed block. A limit block is set at the end of the reciprocating screw. The setting of the limit block can effectively limit the moving range of the moving tube and prevent the moving tube from excessively moving and interfering with the rotating spray assembly. When the lead screw 93 is a reciprocating lead screw, a continuous spiral groove is machined on its surface, and the inner hole of the threaded sleeve 94 is machined with an internal thread that matches the spiral groove. The spiral groove and the internal thread transmit motion and force through sliding contact between the thread tooth surfaces. When the reciprocating lead screw rotates about its axis, the threaded sleeve 94 cannot rotate due to external constraints and is forced to perform linear reciprocating motion along the axis of the reciprocating lead screw. When the lead screw 93 is a conventional lead screw, the outer periphery of the lead screw 93 is provided with an external thread, and the inner hole of the threaded sleeve 94 is machined with an internal thread that matches the external thread. The threaded sleeve 94 and the lead screw 93 are connected by the external and internal threads. When the lead screw 93 rotates about its axis, the threaded sleeve 94 cannot rotate due to external constraints and is forced to perform linear reciprocating motion along the axis of the lead screw 93.

[0057] During actual use, the reciprocating screw is driven to rotate by the driving power member 92, and during the rotation of the reciprocating screw, the movable tube is driven by the threaded sleeve 94 to move along the axial direction of the reciprocating screw to adjust the spraying position of the first nozzle 10; when the temperature of a certain area in the heating device rises and the heat dissipation demand increases, the driving power member 92 can be controlled to drive the reciprocating screw to rotate until the first nozzle 10 moves to the position for spraying the area with increased temperature and increased heat dissipation demand; when the temperature of this area drops to normal temperature, the driving power member 92 can be controlled to drive the reciprocating screw to rotate until the first nozzle 10 moves to the initial position.

[0058] In this embodiment, the mounting frame 91 is located outside the liquid storage device 2, physically separating the drive mechanism 9 from the liquid storage device 2. This simplifies the structural design and sealing requirements of the liquid storage device 2 and reduces the risk of internal contamination or leakage. Furthermore, the entire drive mechanism 9 forms a relatively independent module, making it easy to install, debug, maintain, and replace without affecting the liquid storage device 2. Furthermore, the coordinated transmission method of the lead screw 93 and the threaded sleeve 94 enables small and precise displacement control. When power is off or the drive is stopped, it effectively maintains the position of the movable pipe 8, preventing accidental movement caused by load gravity or external forces. It can withstand large axial loads and has a relatively smooth movement process with minimal impact and vibration. Furthermore, a stopper 95 is provided at the end of the lead screw 93. When the threaded sleeve 94 moves to the end of the lead screw 93, the stopper 95 effectively stops it from moving further, preventing the lead screw 93 and threaded sleeve 94 from dislodging or being damaged due to excessive movement. When the travel limit is reached, the stopper 95 triggers the control system 31 to stop driving the power element 92, preventing damage to the motor or mechanism from overload.

[0059] Based on the above embodiments, Figure 1 As shown, the number of the movable pipelines 8 can be set to two, and the two movable pipelines 8 are respectively arranged on opposite sides of the heating device, and the two movable pipelines 8 are driven to move by the same driving mechanism 9.

[0060] like Figure 3 As shown, one of the moving pipes 8 is connected to the threaded sleeve 94, and the other moving pipe 8 is connected to the moving pipe 8 through the connecting plate 17, as shown in FIG. Figure 1 As shown, the two movable pipelines 8 are respectively arranged on the opposite sides of the heating device. During actual use, the reciprocating screw can be driven to rotate by the driving power part 92. During the rotation of the reciprocating screw, the threaded sleeve 94 drives the movable tube to move along the axial direction of the reciprocating screw, thereby driving the two movable pipelines 8 to move synchronously. During the movement, the two movable pipelines 8 will drive the first nozzle 10 installed thereon to move synchronously.

[0061] Of course, the number and layout positions of the mobile pipelines 8 can also be other solutions that meet the requirements, which are determined according to actual conditions.

[0062] In this specific embodiment, the movement is driven by the same driving mechanism 9, which significantly simplifies the power system and control system 31, reduces hardware costs and system complexity, and ensures the synchronization of the movement of the two movable pipelines 8. In addition, the two movable pipelines 8 can spray on both sides of the heat-generating device at the same time, which can more evenly cover the heat dissipation surface and eliminate the problem of excessive temperature on the side away from the spraying that may be caused by unilateral spraying; synchronous heat dissipation on both sides helps to maintain the balance of the overall temperature distribution of the device and prevents thermal stress concentration or local performance degradation caused by uneven heat dissipation. In addition, the impact, spreading and convergence of the spraying fluid on both sides can form a more effective forced convection field, enhance the disturbance and heat exchange intensity between the fluid and the device surface, and symmetrical spraying helps to reduce the flow dead zone formed on the back or corner of the device during unilateral spraying, making the heat dissipation more comprehensive; according to the spray angle design, the fluids on both sides may intersect in the middle of the device or a specific area, further enhancing the heat exchange effect in that area.

[0063] In a specific embodiment, the first nozzle 10 can be rotatably arranged on the movable pipeline 8. During actual use, the spraying angle of the first nozzle 10 can be adjusted by adjusting the installation angle of the first nozzle 10 relative to the movable pipeline 8.

[0064] The mobile spray assembly can also include a first telescopic tube, one end of which is connected to the mobile pipeline 8, and the other end of the first telescopic tube is connected to the first nozzle 10; the telescopic direction of the first telescopic tube is perpendicular to both the extension direction and the moving direction of the mobile pipeline 8.

[0065] In actual use, by adjusting the telescopic length of the first telescopic tube, the position of the first nozzle 10 in the length direction of the first telescopic tube can be adjusted, and then the spraying position of the first nozzle 10 in the length direction of the first telescopic tube can be adjusted.

[0066] In this specific embodiment, by rotatably mounting the first nozzle 10 on the movable pipe 8, when the type or model of the heating device in the cabinet body 1 changes, the spraying angle of the first nozzle 10 can be adjusted by adjusting the installation angle of the first nozzle 10 relative to the movable pipe 8, thereby enabling the spraying angle of the first nozzle 10 to adapt to different heating devices, thereby achieving a specific spraying heat dissipation solution for different heating devices. In addition, when multiple layers of heating devices are installed in the cabinet body 1, and the types or models of the heating devices in different layers are different, the installation angles of the first nozzles 10 corresponding to the heating devices in different layers in the movable pipe 8 can be adjusted separately to accommodate the different heat dissipation areas of the heating devices in different layers. In addition, by providing a first telescopic tube, the position of the first nozzle 10 in the length direction of the first telescopic tube can be adjusted. When the type or model of the heating device in the cabinet body 1 changes, the position of the first nozzle 10 in the length direction of the first telescopic tube can be adjusted by adjusting the extension distance of the first telescopic tube in the corresponding layer, thereby enabling the first nozzle 10 to adapt to the change in the required heat dissipation area in the length direction of the first telescopic tube.

[0067] On the basis of the above embodiment, at least two movable spraying assemblies may be provided, and the moving directions of the at least two movable spraying assemblies are different.

[0068] Specifically, two mobile spraying assemblies can be provided, one of which moves along Figure 2 The middle cabinet body 1 moves in the length direction, and the other moving spray assembly moves along Figure 2 The mobile spray assemblies move in the width direction of the cabinet body 1; in actual use, when the temperature of a certain area of ​​the heating device rises and the heat dissipation requirement increases, it is first necessary to determine the specific position of the area with increased heat dissipation requirement, obtain the position information, and control one of the mobile spray assemblies to move along the length direction of the cabinet body 1 to the heat dissipation position corresponding to the position information according to the position information, and control the other mobile spray assembly to move along the width direction of the cabinet body 1 to the heat dissipation position corresponding to the position information, so that the two mobile spray assemblies can dissipate heat for the area with increased heat dissipation requirement at the same time, thereby improving the heat dissipation effect. Alternatively, the heat dissipation areas that the two mobile spray assemblies are responsible for can be independent of each other. In actual use, when the temperature of a certain area of ​​the heating device rises and the heat dissipation requirement increases, it is first necessary to determine the specific position of the area with increased heat dissipation requirement, obtain the position information, and determine which mobile spray assembly's heat dissipation area the heat dissipation area belongs to according to the position information, and control the corresponding mobile spray assembly to move to the position corresponding to the position information, thereby achieving heat dissipation for the area with increased heat dissipation requirement.

[0069] In this specific embodiment, at least two mobile spray assemblies are provided, and spray assemblies in different directions can cover different surfaces of the heating device, or penetrate the complex internal structure of the device from different angles. The spray assembly moving in one direction may form a "heat dissipation blind spot" in the recessed part, leeward side or geometric dead angle of the device. Multi-directional coordinated spraying can ensure that the cooling medium covers the entire heat source surface without dead angles; the overlapping of motion trajectories can form a denser and more uniform "cooling grid" on the surface of the device, significantly improving the overall heat dissipation uniformity and avoiding local hot spots. In addition, for irregularly shaped heating devices, moving paths in different directions can be designed to precisely fit their contours to ensure the optimal spray distance and angle. In addition, jets from different directions can form an "impact flow" effect, generating violent turbulence in the intersection area, greatly enhancing the local heat transfer coefficient; the moving speed, flow rate or start and stop of each mobile spray assembly can be independently controlled according to the real-time temperature of different areas of the equipment, giving priority to cooling high-temperature areas to achieve intelligent thermal management.

[0070] In a specific embodiment, the rotary spray assembly includes a rotary main line 26, a plurality of rotary branch lines 27 and a plurality of second nozzles 28, wherein one end of the rotary main line 26 is located in the liquid storage device 2, and the other end of the rotary main line 26 extends from the liquid storage device 2 to the cabinet body 1, and the length direction of the rotary main line 26 located in the cabinet body 1 is arranged along the height direction of the cabinet body 1; one end of the rotary branch line 27 is connected to the part of the rotary main line 26 located in the cabinet body 1, and the extension direction of the rotary branch line 27 is perpendicular to the length direction of the rotary main line 26; the second nozzle 28 is installed at the end of the rotary branch line 27, and the spraying direction of the second nozzle 28 is toward the heating equipment in the cabinet body 1; the second nozzle 28 is rotatable around its central axis.

[0071] The rotary spray assembly in this specific embodiment is used to transfer the coolant in the liquid storage device 2 to the second nozzle 28 through the liquid conduit, so that the coolant is evenly sprayed on the surface of the heat-generating device with high heat dissipation requirements. The heat-generating device here can be the CPU (Central Processing Unit) of the server system; the second nozzle 28 is a structure that can automatically rotate around its own central axis without the aid of external force. Therefore, when some nozzle holes are blocked, the blocked nozzle holes can be flushed by increasing the flow rate without affecting the heat dissipation effect.

[0072] In actual use, Figure 1 As shown, the coolant in the liquid storage device 2 is sprayed out by the second nozzle 28 through the rotating main line 26 and the rotating branch line 27. The second nozzle 28 rotates around its own central axis while spraying the coolant. During the rotation process, the coolant can be sprayed on the surface of the heating device, thereby dissipating the heat from the surface of the heating device.

[0073] The rotating main line 26 in this embodiment can be Figure 1 The fastening clip 29 is fixed to the inner wall of the cabinet body 1 , occupying only the narrow space on the side of the cabinet body 1 , thereby releasing more volume of the cabinet body 1 for electronic equipment.

[0074] Since the second nozzle 28 in this specific embodiment can rotate around its own central axis, in actual use, the second nozzle 28 is generally used to dissipate heat in areas with higher heat dissipation requirements. During the rotation process, the second nozzle 28 can improve the uniformity of coolant spraying and improve the heat dissipation effect.

[0075] The rotating branch pipe 27 in this specific embodiment can be set as a rotating nozzle liquid guide pipe made of metal material, and a valve can be added.

[0076] In this specific embodiment, the rotating main line 26 penetrates along the height direction of the cabinet to achieve full longitudinal coverage, and the rotating branch line 27 radiates to both sides perpendicular to the main line to form a lateral expansion, which can achieve dead-angle coverage of the three-dimensional space in the cabinet; in addition, the second nozzle 28 rotates around the axis, and the jet flow can dynamically sweep the surface of the heating equipment to avoid the local dry burning area of ​​fixed spraying; in addition, the nozzle speed is dynamically adjusted according to the temperature of the equipment: the high-temperature area accelerates the rotation to enhance heat dissipation, and the low-temperature area decelerates to save cooling capacity, effectively saving energy.

[0077] On the basis of the above embodiment, in order to enable the second nozzle 28 to rotate around its own central axis, the second nozzle 28 can include a nozzle body, a bearing 282 and a snap 281; wherein, the first end of the nozzle body is connected to the rotating branch pipe 27; a speed change section and a Y-shaped frame 283 and a rotating fan 284 installed on the speed change section are provided in the nozzle body, and the radial dimension of the cross section of the speed change section is smaller than the radial dimension of the cross section of other positions of the nozzle body; the second end of the nozzle body is provided with a spraying part 285 for spraying coolant; the bearing 282 is sleeved on the outer periphery of the nozzle body, and the inner ring of the bearing 282 is fixedly connected to the nozzle body; the snap 281 is fixedly connected to the outer ring of the bearing 282, and the snap 281 is connected to the rotating branch pipe 27.

[0078] In this specific embodiment, the rotating fan 284 is suspended on the Y-shaped frame 283.

[0079] like Figure 4 As shown, the buckle 281 is sleeved on the outer ring of the bearing 282, and the buckle 281 is connected to the rotating branch pipe 27 to achieve the fixed installation of the second nozzle 28. Figure 5 As shown, the bearing 282 is sleeved on the outer periphery of the nozzle body, and the inner ring of the bearing 282 is fixedly connected to the nozzle body. The nozzle body and the Y-shaped frame 283, rotating fan 284 and spraying part 285 arranged in the nozzle body can all rotate synchronously with the nozzle body.

[0080] During actual use, coolant enters the nozzle body through the rotating branch line 27 and the first end of the nozzle body. As the coolant flows through the speed-changing section, the radial dimension of the cross-section of the speed-changing section decreases, increasing the flow of coolant in the speed-changing section, thereby driving the rotation of the rotating fan 284. The rotating fan 284, the Y-shaped frame 283, and the nozzle body are all integrated structures. Therefore, the rotation of the rotating fan 284 drives the nozzle body to rotate. During the rotation of the nozzle body, the spraying portion 285 located at the second end of the nozzle body rotates synchronously with the nozzle body. In this specific embodiment, the second end of the nozzle body is the end of the nozzle body away from the first end.

[0081] It should be noted that the main function of the Y-shaped frame 283 in this specific embodiment is to divide the coolant flowing through the speed change section into three parts, further increase the flow rate of the coolant flowing through the speed change section, and increase the rotation speed of the rotating fan 284 and the spraying part 285.

[0082] In this specific embodiment, when the coolant flows through the speed-changing section with a suddenly reduced cross-section, the flow velocity increases sharply according to the Bernoulli principle, forming a high-speed jet to impact the rotating fan 284, and more potential energy of the coolant is converted into mechanical energy, driving the rotating fan 284 to rotate; the Y-shaped frame 283 located in the speed-changing section performs tangential guidance on the fluid, forming a high-speed vortex to impact the fan blades, which can effectively increase the torque.

[0083] On the basis of the above embodiment, the second nozzle 28 can be rotatably arranged on the rotating branch pipe 27. During actual use, the spraying angle of the second nozzle 28 can be adjusted by adjusting the installation angle of the second nozzle 28 relative to the rotating branch pipe 27.

[0084] The rotary spray assembly may further include a second telescopic tube, one end of which is connected to the rotary branch pipe 27 , and the other end of which is connected to the second nozzle 28 ; the telescopic direction of the second telescopic tube is along the central axis of the second nozzle 28 .

[0085] In actual use, by adjusting the telescopic length of the second telescopic tube, the position of the second nozzle 28 in the length direction of the second telescopic tube can be adjusted, and the distance between the second nozzle 28 and the surface of the heating device can be adjusted.

[0086] In this specific embodiment, by rotatably mounting the second nozzle 28 on the rotating branch pipe 27, when the type or model of the heating device within the cabinet body 1 changes, the spraying angle of the second nozzle 28 can be adjusted by adjusting the mounting angle of the second nozzle 28 relative to the rotating branch pipe 27. This allows the spraying angle of the second nozzle 28 to adapt to the different heating devices, thereby achieving a specific spraying and cooling solution for each heating device. Furthermore, when the cabinet body 1 is equipped with multiple layers of heating devices, and the types or models of the heating devices on different layers differ, the mounting angles of the second nozzles 28 on the rotating branch pipe 27 corresponding to the heating devices on different layers can be adjusted to accommodate the differences in the heat dissipation areas of the heating devices on different layers. Furthermore, by providing a second telescopic tube, the position of the second nozzle 28 along its length can be adjusted. When the type or model of the heating device within the cabinet body 1 changes, the distance between the second nozzle 28 and the surface of the corresponding heating device can be adjusted by adjusting the extension distance of the second telescopic tube on the corresponding layer, thereby adapting the second nozzle 28 to the changes in the height dimension of the heating device.

[0087] In a specific embodiment, there are multiple rotating branch pipes 27, and the multiple rotating branch pipes 27 are arranged at intervals along the length direction of the rotating main pipe 26; and / or, one end of the rotating branch pipe 27 connected to the rotating main pipe 26 is rotatable around the rotating main pipe 26.

[0088] When multiple layers of heating equipment are installed in the cabinet body 1, multiple rotating branch pipes 27 can be spaced apart along the length direction of the rotating main pipe 26, so that different rotating branch pipes 27 correspond to different layers of heating equipment, so that all heating equipment have corresponding second nozzles 28 for spraying and dissipating heat.

[0089] During actual use, when there are differences in the positions of high-requirement heat dissipation areas in heating devices at different layers, the heat dissipation area corresponding to the second nozzle 28 can be adjusted by adjusting the rotation angle of the rotating branch pipe 27 relative to the rotating main pipe 26 to adapt to the heat dissipation requirements of different heating devices.

[0090] In this specific embodiment, one end of the rotating branch pipe 27 connected to the rotating main pipe 26 can be rotatably arranged around the rotating main pipe 26, breaking through the rigid limitations of traditional fixed sprinklers; the installation angle of the rotating branch pipe 27 relative to the rotating main pipe 26 can be adjusted according to actual conditions, and can be applied to different heating equipment to meet diverse heat dissipation needs.

[0091] In a specific embodiment, the movable spray assembly is provided with a first pressure sensor for detecting the spray pressure; and the rotary spray assembly is provided with a second pressure sensor for detecting the spray pressure.

[0092] During actual use, when the first pressure value detected by the first pressure sensor is less than the first preset pressure value, it indicates that the mobile spray assembly is in normal working condition; when it is detected that the first pressure value detected by the first pressure sensor is greater than the first preset pressure value and less than the second preset pressure value, and the second preset pressure value is greater than the first preset pressure value, it indicates that the mobile spray assembly may be blocked and the spray flow is affected. The heat dissipation of the heating equipment can be further observed, or relevant warning information can be issued; when it is detected that the first pressure value detected by the first pressure sensor is greater than the second preset pressure value, it indicates that the mobile spray assembly is seriously blocked or the spray flow is seriously insufficient, which has affected the normal heat dissipation of the heating equipment. It is necessary to control the mobile spray assembly to stop working and perform relevant maintenance.

[0093] When the second pressure value detected by the second pressure sensor is less than the third preset pressure value, it indicates that the rotary spray assembly is in normal working condition; when it is detected that the second pressure value detected by the second pressure sensor is greater than the third preset pressure value and less than the fourth preset pressure value, and the fourth preset pressure value is greater than the third preset pressure value, it indicates that the rotary spray assembly may be blocked, but because the spray end of the rotary spray assembly can rotate around its own central axis, it can still achieve uniform spraying of the heat dissipation area, and the impact on heat dissipation is small. At this time, the spray flow rate can be increased to observe whether the blocked spray hole can be flushed by increasing the spray flow rate, and further observe the heat dissipation of the heating equipment, or issue relevant warning information; when it is detected that the second pressure value detected by the second pressure sensor is greater than the fourth preset pressure value, it indicates that the rotary spray assembly is seriously blocked or the spray flow rate is seriously insufficient, which has affected the normal heat dissipation of the heating equipment. It is necessary to control the rotary spray assembly to stop working and perform relevant maintenance.

[0094] In this specific embodiment, by arranging a first pressure sensor in the mobile spray assembly, real-time monitoring of the spray pressure of the spray hole of the mobile spray assembly can be achieved, so as to facilitate timely acquisition of spray pressure information, and then timely adjustment can be made when the spray pressure of the mobile spray assembly does not meet the requirements, so as to avoid affecting the heat dissipation effect; the rotary spray assembly is provided with a second pressure sensor for detecting the spray pressure, so as to achieve real-time monitoring of the spray pressure of the spray hole of the rotary spray assembly, so as to facilitate timely acquisition of spray pressure information, and then timely adjustment can be made when the spray pressure of the rotary spray assembly does not meet the requirements, and the spray hole can be flushed open by adjusting the flow rate in the initial increase stage of the spray pressure, so as to avoid affecting the heat dissipation effect.

[0095] Based on the above embodiment, multiple first temperature detection elements can be provided in the cabinet body 1, and the first temperature detection elements are used to detect first temperature information at different positions of the heat-generating device.

[0096] During actual use, first, it is necessary to obtain all the first temperature information detected by multiple first temperature detection members, and then, based on the obtained first temperature information, determine whether there is a warning temperature value exceeding the first preset temperature. If so, obtain the position information of the first temperature detection member corresponding to the warning temperature value, and determine based on the position information whether the area detected by the first temperature detection member belongs to the heat dissipation area corresponding to the mobile spray component or the heat dissipation area corresponding to the rotary spray component, or whether the area detected by the first temperature detection member belongs to the overlapping area of ​​the heat dissipation area corresponding to the mobile spray component and the heat dissipation area corresponding to the rotary spray component; when the area detected by the first temperature detection member belongs to the heat dissipation area corresponding to the mobile spray component, the mobile spray component is controlled to move to the area corresponding to this position information for spraying; when the area detected by the first temperature detection member belongs to the heat dissipation area corresponding to the rotary spray component, the rotary spray component is controlled to increase the spray flow rate; when the area detected by the first temperature detection member belongs to the overlapping area of ​​the heat dissipation area corresponding to the mobile spray component and the heat dissipation area corresponding to the rotary spray component, the mobile spray component is controlled to move to the area corresponding to this position information for spraying and the rotary spray component is controlled to increase the spray flow rate.

[0097] In this specific embodiment, by setting multiple first temperature detection components at different positions of the heating device, temperature information at different positions of the heating device can be obtained in real time during actual use. When the temperature of a certain area of ​​the heating device rises and the heat dissipation demand increases, the mobile spray component or the rotary spray component can be controlled in time to make relevant adjustments, so as to implement corresponding heat dissipation solutions for areas with different heat dissipation demands in the heating device, thereby meeting the heat dissipation requirements while reducing energy waste.

[0098] In a specific embodiment, the liquid storage device 2 includes a liquid storage box body and a liquid inlet hole 2B and a liquid outlet hole 2A arranged in the liquid storage box body; a water pumping power component 4 and a transfer tube 6 are provided in the liquid storage box body, the first end of the transfer tube 6 is connected to the water pumping power component 4, the second end of the transfer tube 6 is connected to the movable spray assembly, and the third end of the transfer tube 6 is connected to the rotary spray assembly; the parts of the movable spray assembly and the rotary spray assembly used to connect with the transfer tube 6 are both deformable hoses.

[0099] The liquid storage device 2 in this specific embodiment is used to discharge the coolant with a higher temperature in the liquid storage box and introduce low-temperature coolant to enhance the heat dissipation effect, and on the other hand provide coolant for the entire cabinet.

[0100] In order to avoid the situation where the coolant temperature in the liquid storage device 2 is uneven, as shown in FIG. Figure 2 As shown, two liquid outlet holes 2A can be provided on the upper side of the front end of the liquid storage box body, and two liquid inlet holes 2B can be provided on the lower side of the front end of the liquid storage box body.

[0101] like Figure 1 As shown, the water-pumping power component 4 can be set as a submersible pump, which is electrically connected to an external power supply and controlled by a control system 31. The liquid outlet end of the submersible pump is connected to one end of the liquid outlet pipe 5, and the other end of the liquid outlet pipe 5 is connected to a transfer pipe 6. The second end of the transfer pipe 6 is provided with two interfaces, which are respectively connected to two first hoses 7. The other ends of the two first hoses 7 are respectively connected to two mobile pipelines 8. The mobile pipelines 8 can be set to be made of metal; the third end of the transfer pipe 6 is connected to one end of the second hose 25, and the other end of the second hose 25 is connected to a rotating main pipeline 26 made of metal.

[0102] like Figure 1 As shown, the two first hoses 7 are symmetrically arranged about the middle section of the cabinet body 1, the second hose 25 is provided with a bend, and the second hose 25 is located on the lower side of the first hose 7. During actual use, when the movable pipeline 8 is driven to move by the driving mechanism 9, the setting position of the second hose 25 effectively avoids the first hose 7, thereby avoiding interference between the first hose 7 and the second hose 25.

[0103] In this embodiment, both the mobile spray assembly and the rotary spray assembly are connected to the pumping element 4 via a hose. During actual use, when the mobile spray assembly moves, the hose connecting the mobile spray assembly and the pumping element 4 deforms, thereby ensuring sufficient travel for the mobile spray assembly to meet its movement requirements. Furthermore, the hose connecting the rotary spray assembly to the pumping element 4 effectively prevents damage to the connection when the rotary spray assembly is displaced or vibrates, thereby improving connection reliability.

[0104] Based on the above embodiment, a second temperature detection member for detecting the coolant temperature, a liquid level sensor for detecting the liquid level height in the liquid storage tank, and a water quality detection mechanism for detecting the coolant quality in the liquid storage tank can be set in the liquid storage tank.

[0105] During actual use, when the second temperature sensing element detects that the temperature of the coolant in liquid storage device 2 is higher than a preset temperature value, coolant at a lower temperature can be introduced through liquid inlet 2B, and coolant at a higher temperature can be discharged through liquid outlet 2A, so that the coolant temperature in liquid storage device 2 meets the required level. When the liquid level sensor detects that the coolant level in liquid storage device 2 is lower than the minimum level, liquid inlet 2B is controlled to introduce coolant. When the liquid level sensor detects that the coolant level in liquid storage device 2 is higher than or reaches the maximum level, liquid inlet 2B is controlled to stop introducing coolant, or liquid outlet 2A is controlled to discharge coolant.

[0106] The water quality detection mechanism may include a conductivity sensor and a pH detection element. The conductivity sensor is mainly used to detect ion contamination, and the pH detection element is mainly used to detect the pH value of the coolant. Of course, the water quality detection mechanism may also include other detection structures, which are determined according to actual conditions.

[0107] In this embodiment, the second temperature sensor monitors the core temperature of the coolant in the reservoir in real time, facilitating dynamic adjustment of the coolant temperature. The liquid level sensor monitors the coolant level in the reservoir in real time, facilitating timely refilling. Furthermore, the water quality sensor monitors the quality of the coolant in the reservoir, enabling prompt replacement or other appropriate action if the coolant quality does not meet requirements.

[0108] In a specific embodiment, the cabinet also includes a filtering device 3, which includes a filtering box and a filter plate 12 arranged in the filtering box; the filtering device 3 is located between the cabinet body 1 and the liquid storage device 2, and the liquid sprayed by the spraying device flows back to the liquid storage device 2 through the filter plate 12.

[0109] The filter device 3 is mainly used to clean the coolant, thereby reducing the risk of blockage of the spray hole and the liquid guide tube. Figure 9 As shown, both sides of the top of the filter device 3 are provided with rectangular grooves 23 adapted to the mobile pipeline 8 and the rotating main pipeline 26. Figure 1 As shown, a guide groove 22 is provided on the side of the cabinet body 1. During the actual installation process, the mobile pipeline 8 and the rotating main pipeline 26 are extended into the cabinet body 1 through the guide groove 22 and the rectangular groove 23. The rotating main pipeline 26 is at the front end of the rectangular groove 23, and the mobile pipeline 8 reciprocates in the other space of the rectangular groove 23. A limit member 95 is provided at the end of the lead screw 93 away from the driving power member 92 to prevent the mobile pipeline 8 and the rotating main pipeline 26 from interfering with each other.

[0110] In this embodiment, the filter device 3 is provided to filter the coolant flowing back into the liquid storage device 2, preventing impurities from entering the liquid storage device 2 and effectively preventing pipe blockage. Furthermore, the filter device 3 is disposed between the cabinet body 1 and the liquid storage device 2, effectively and rationally utilizing space. The coolant sprayed by the spray device flows through the filter device 3 under the action of gravity and flows back into the liquid storage device 2, achieving efficient use of space.

[0111] On the basis of the above embodiment, a slide groove 11 can be provided on the side wall of the filter box, a limiting component is provided on the outside of the slide groove 11, and the filter plate 12 is detachably inserted into the slide groove 11; the limiting component includes a limiting plate 14 and a limiting screw 15 that passes through the limiting plate 14 and is rotatable relative to the limiting plate 14, and the part of the filter plate 12 extending out of the slide groove 11 is provided with a limiting screw hole 16 for cooperating with the limiting screw 15.

[0112] like Figure 9 As shown, a chute 11 is provided at the front of the filter housing, a filter plate 12 is disposed within the chute 11, a retaining groove 13 is provided at the rear of the filter housing inner cavity, and the retaining plate 12 is adapted to fit within the filter plate 12. A retaining plate 14 is fixedly connected to the front of the filter housing, located in front of the chute 11. The top of the retaining plate 14 is slidably connected to the filter housing via an opening. A retaining screw hole 16 is provided at the top of the filter plate 12, which is adapted to fit within a retaining screw 15. By rotating the retaining screw 15 to move it out of the retaining screw hole 16, the filter plate 12 can be periodically removed from the filter housing for cleaning.

[0113] In this specific embodiment, the installation position of the filter plate 12 can be fixed by setting a limit component, and the filter plate 12 can be disassembled. The detachable setting of the filter plate 12 makes it convenient to take out the filter plate 12 when the filter plate 12 needs to be cleaned or replaced during actual use, and the operation process is convenient.

[0114] Based on the above embodiment, the mobile spray assembly is provided with a connecting piece facing the filter plate 12 and a cleaning brush 19 located at the end of the connecting piece, and the cleaning brush 19 is provided in contact with the filter plate 12; the mobile spray assembly drives the cleaning brush 19 to move relative to the filter plate 12 to clean the filter plate 12.

[0115] like Figure 3 As shown, the connecting part includes a connecting plate 17 for connecting the two movable pipes 8 and a connecting block 18 connected to the connecting plate 17 at one end and the cleaning brush 19 at the other end. During actual use, when the mobile spray assembly is driven to move by the driving mechanism 9, the cleaning brush 19 will move relative to the filter plate 12 to clean the filter plate 12.

[0116] In this specific embodiment, the movement of the mobile spray assembly drives the cleaning brush 19 to move relative to the filter plate 12, thereby cleaning the filter plate 12. The structure is compact and does not require an additional power structure to drive the cleaning brush 19 to move, which can effectively reduce the number of parts and reduce costs.

[0117] In a specific embodiment, if Figure 1 As shown, a tray 24 for carrying heating equipment is provided in the cabinet body 1; a plurality of drainage holes 21 are provided at the bottom of the tray 24, and a first baffle that is completely closed along the circumferential direction is provided on the outer peripheral side of the tray 24, and the protrusion height of the first baffle is higher than the height of the surface of the tray 24 for carrying the heating equipment.

[0118] like Figure 10 As shown, the tray 24 is fixed to the cabinet body 1 via four hanging ears 20 .

[0119] A liquid guide plate 30 is provided on the lower side of the tray 24. Along the length direction of the cabinet body 1, the height of the bottom surface of the liquid guide plate 30 gradually decreases from the middle to the two ends; along the width direction of the cabinet body 1, a second baffle is provided on both sides of the liquid guide plate 30, and the protrusion height of the second baffle is higher than the height of the highest position of the bottom surface of the liquid guide plate 30.

[0120] The cabinet body 1 is located above the filtering device 3, and the heating device is located on the tray 24 of the cabinet body 1. During actual use, insulating coolant can be used. In order to avoid corrosion caused by long-term contact between the coolant and the heating device, a layer of insulating material can be coated on the surface of the heating device, which will not affect the heat dissipation. The heating device here can be a server system without a chassis.

[0121] During actual use, the heat-generating device is placed within the tray 24. The coolant sprayed by the spray device flows through the surface of the heat-generating device and then converges into the tray 24. It is then discharged through the drainage holes 21 of the tray 24 to the liquid guide plate 30. In this embodiment, a first baffle is provided on the outer side of the tray, completely enclosing the entire tray along the circumference. When the coolant flow rate from the spray device is relatively high, the tray 24 can temporarily store a certain level of coolant, ensuring that the coolant in the tray 24 is constantly refreshed, further enhancing the heat dissipation effect.

[0122] In addition, in this specific embodiment, along the length direction of the cabinet body 1, the liquid guide plate 30 is higher in the middle and lower on both sides, so that the coolant can flow out from the middle of the liquid guide plate 30 to both sides, and along the width direction of the cabinet body 1, a second baffle is provided on both sides of the liquid guide plate 30 to prevent the coolant from flowing out of the cabinet body 1, so that the coolant can flow back to the filter device 3 according to the guidance of the liquid guide plate 30, and finally flow back to the liquid storage device 2.

[0123] In addition to the above-mentioned cabinet, the present application also provides a control method applied to the above-mentioned cabinet. The cabinet body 1 of the cabinet is provided with multiple first temperature detection elements, and the first temperature detection elements are used to detect first temperature information at different positions of the heating device. The control method includes:

[0124] Step S1: Acquire first temperature information detected by all first temperature detection components.

[0125] Step S2, determining whether there is a warning temperature value exceeding a first preset temperature in the first temperature information, if so, obtaining the position information of the first temperature detection component corresponding to the warning temperature value; if not, returning to step S1.

[0126] Step S3, determining whether the position information belongs to the spraying area of ​​the mobile spray component, if so, controlling the mobile spray component to move to the area corresponding to the position information for spraying; if not, controlling the rotating spray component to increase the spray flow rate.

[0127] In this specific embodiment, by setting up a first temperature detection component, the first temperature information of different positions of the heating device can be obtained in real time. When the first temperature information is higher than the warning temperature value, the mobile spray component is promptly controlled to focus on spraying heat in this area or the rotating spray device is controlled to increase the spray flow rate. Different heat dissipation schemes can be implemented for positions with different heat dissipation requirements in the heating equipment, and key spraying can be performed on areas with higher heat dissipation requirements, effectively reducing energy consumption while ensuring the heat dissipation effect.

[0128] In addition to the above cabinet, the present application also provides a control method applied to the above cabinet, wherein the mobile spray assembly is provided with a first pressure sensor for detecting the spray pressure and a first early warning device; the rotary spray assembly is provided with a second pressure sensor for detecting the spray pressure and a second early warning device; the control method includes:

[0130] Step S02, determining whether the first pressure value is greater than a first preset pressure value, if so, controlling the first warning device to issue a warning message, and proceeding to step S03; if not, returning to step S01.

[0131] Step S03, determining whether the first pressure value is greater than the second preset pressure value, and the second preset pressure value is greater than the first preset pressure value; if so, controlling the mobile spray component to stop working, if not, maintaining the current working state of the mobile spray component.

[0132] Step S04, determining whether the second pressure value is greater than the third preset pressure value, if so, controlling the second warning device to issue a warning message, controlling to increase the flow rate of the rotary spray assembly, and entering step S05; if not, returning to step S03.

[0133] Step S05, determining whether the second pressure value is greater than a fourth preset pressure value, and the fourth preset pressure value is greater than the third preset pressure value; if so, controlling the rotary spray assembly to stop working, if not, maintaining the current working state of the rotary spray assembly.

[0134] In this specific embodiment, by setting a first pressure sensor and a first warning device, real-time monitoring of the spray pressure of the spray hole of the mobile spray assembly can be achieved, so as to facilitate timely acquisition of spray pressure information, and then make timely adjustments when the spray pressure of the mobile spray assembly does not meet the requirements, so as to avoid affecting the heat dissipation effect; the rotary spray assembly is provided with a second pressure sensor for detecting the spray pressure, so as to achieve real-time monitoring of the spray pressure of the spray hole of the rotary spray assembly, so as to facilitate timely acquisition of spray pressure information, and then make timely adjustments when the spray pressure of the rotary spray assembly does not meet the requirements, and flush the spray hole by adjusting the flow rate in the initial increase stage of the spray pressure, so as to avoid affecting the heat dissipation effect.

[0135] In addition to the above cabinet, the present application also provides a control method applied to the above cabinet, the cabinet is provided with Figure 12 The control system 31 shown in the figure includes a single-chip microcomputer 33, a display 34, a sensor 35, a WIFI module 36 and a cloud platform 37. The sensors in this specific embodiment include a first temperature detection component in the cabinet body 1 for detecting the temperature of different positions of the heating equipment, a second temperature detection component arranged in the liquid storage device 2, a first pressure sensor arranged in the mobile spray assembly for detecting the injection pressure, and a second pressure sensor arranged in the rotary spray assembly for detecting the injection pressure. The mobile spray assembly is provided with a first valve 38 for controlling its flow rate, and the rotary spray device is provided with a second valve 39 for controlling its flow rate. The control system 31 is used to control the opening and closing of the first valve 38 and the second valve 39, the operation of the pumping power component 4, the action of the drive mechanism 9, and the filling and discharge 32 of the water tank.

[0136] In actual use, the control methods applied to the above cabinets include:

[0137] Step S001 , controlling and starting the water pumping power component 4 and the driving power component 92 .
