Description

Technical Field

[0001] This application relates to the technical field of heat dissipation, and particularly to a cabinet, a control method and an electronic device. Background Art

[0002] Current cabinets all use fixed nozzles. During the spray cooling process, coolant is sprayed on different heat dissipation areas with the same spray intensity, which cannot ensure that all areas can be evenly contacted with the coolant, and is not suitable for the situation where the heat dissipation requirements of components in different areas of the server system are different.

[0003] When the temperature of a local area of the server is relatively high and the heat dissipation intensity needs to be increased, the overall spray intensity needs to be increased, resulting in waste of resources. When the temperature of a local area of the server is relatively low and the heat dissipation intensity needs to be reduced, considering the heat dissipation requirements of other areas, the spray intensity cannot be directly reduced, also resulting in waste of resources. Summary of the Invention

[0004] This application provides a cabinet to at least solve the problem of resource waste caused by using the same spray intensity for heating areas with different temperatures in related technologies.

[0005] This application provides a cabinet, including: A cabinet body for placing heating devices; A liquid storage device with coolant stored inside; A spray device, one end of which is located inside the liquid storage device, and the other end sprays coolant towards the heating devices inside the cabinet body; the spray device includes a movable spray assembly and a rotating spray assembly. The movable spray assembly is movably arranged inside the cabinet body in at least one direction to adjust the spray position; the spraying end of the rotating spray assembly is rotatably arranged around the central axis.

[0006] This application also provides a control method applied to the cabinet described in any one of the above. A plurality of first temperature detectors are arranged inside the cabinet body, and the first temperature detectors are used to detect the first temperature information at different positions of the heating devices; the control method includes: Obtain the first temperature information detected by all the first temperature detectors; Judge whether there is a warning temperature value exceeding the first preset temperature in the first temperature information. If so, obtain the position information of the first temperature detector corresponding to the warning temperature value; if not, return to the previous step; Judge whether the position information belongs to the spraying area of the movable spray assembly. If so, control the movable spray assembly to move to the area corresponding to the position information for spraying; if not, control the rotating spray assembly to increase the spray flow rate.

[0007] The present application also provides a control method, which is applied to the cabinet described in any one of the above. The mobile spraying assembly is provided with a first pressure sensor for detecting the spraying pressure and a first warning device; the rotating spraying assembly is provided with a second pressure sensor for detecting the spraying pressure and a second warning device; the control method includes: Obtain a first pressure value detected by the first pressure sensor and a second pressure value detected by the second pressure sensor; Determine whether the first pressure value is greater than a first preset pressure value. If so, control the first warning device to send a warning message and proceed to the next step; if not, return to the previous step; Determine whether the first pressure value is greater than a second preset pressure value, and the second preset pressure value is greater than the first preset pressure value.

[0009] The beneficial effects of the present application are as follows. Since the spraying device includes a mobile spraying assembly and a rotating spraying assembly, during actual use, the heat dissipation areas corresponding to the mobile spraying assembly and the rotating spraying assembly can be reasonably allocated according to the different heat dissipation requirements of different positions of the heating device. Specifically, the rotating spraying assembly can correspond to the heat dissipation area with higher heat dissipation requirements, and the mobile spraying assembly can correspond to the heat dissipation area with lower heat dissipation requirements. In addition, when the temperature at a certain position in the heat dissipation area corresponding to the mobile spraying assembly in the heating device rises and the heat dissipation requirement increases, the mobile spraying assembly can be controlled to move to the position corresponding to this area and spray the area with the increased temperature intensively, thereby improving the heat dissipation effect and meeting the heat dissipation requirements. When the temperature at a certain position in the heat dissipation area corresponding to the rotating spraying assembly in the heating device rises and the heat dissipation requirement increases, the heat dissipation effect can be improved by increasing the spraying flow rate of the rotating spraying assembly to meet the heat dissipation requirements. Therefore, the technical problem of resource waste caused by using the same spraying intensity for heating areas with different temperatures in the related art can be solved, and the technical effect of reasonably arranging the spraying components for heating areas with different heat dissipation requirements and focusing on heat dissipation for areas with higher heat dissipation requirements can be achieved.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] It should be noted that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. The terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. The terms "parallel", "perpendicular", and "equal" include the described situations and situations similar to the described situations, and the range of the similar situations is within an acceptable deviation range, where the acceptable deviation range is determined by those of ordinary skill in the art considering the measurements being discussed and the errors associated with the measurements of specific quantities (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, within 5° deviation; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, within 5° deviation.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0028] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0029] The length direction and width direction of the cabinet body 1 mentioned in the present application document are two mutually perpendicular directions in the cabinet body. In the case where the shape of the cabinet body 1 changes, the length direction and width direction of the cabinet body 1 can change.

[0030] Embodiments of the present application provide a cabinet, including a cabinet body 1, a liquid storage device 2 and a spraying device; the cabinet body 1 is used for placing heat-generating devices; the interior of the liquid storage device 2 stores a coolant; one end of the spraying device is located inside the liquid storage device 2, and the other end sprays the coolant towards the heat-generating devices inside the cabinet body 1; the spraying device includes a movable spraying component and a rotating spraying component, and the movable spraying component is movably arranged inside the cabinet body 1 in at least one direction to adjust the spraying position; the spraying end of the rotating spraying component is rotatably arranged around the central axis.

[0031] The heat-generating device in this embodiment can be a server or a heat-generating device that meets the requirements, which is specifically determined according to the actual situation and will not be elaborated here. The heat-generating devices can be arranged in multiple layers along the height direction inside the cabinet body 1, and the movable spraying component and the rotating spraying component are both provided with nozzles for the heat-generating devices on the corresponding layers to dissipate heat from the heat-generating devices on different layers.

[0032] During actual use, generally, the heat dissipation requirements for the heat dissipation area of the heat-generating devices corresponding to the movable spraying component are relatively low; the heat dissipation requirements for the heat dissipation area of the heat-generating devices corresponding to the rotating spraying component are relatively high. According to the heat dissipation requirements of different positions of the heat-generating devices, the different heat dissipation areas of the heat dissipation devices are reasonably divided so that the different heat dissipation areas correspond to the movable spraying component or the rotating spraying component respectively. According to the size of the heat-generating devices and the distribution requirements of different heat dissipation areas, the number of the movable spraying component and the rotating spraying component can be reasonably adjusted.

[0033] The liquid storage device 2 can be arranged on the lower side of the cabinet body 1. During use, the spraying device pumps out the coolant in the liquid storage device 2 and sprays it onto the surface of the heat-generating devices inside the cabinet body 1, and the sprayed coolant can flow back to the liquid storage device 2 under the action of gravity to realize the recycling of the coolant.

[0034] In this specific embodiment, it can be that the same movable spraying component is movably arranged in at least one direction, or different movable spraying components are respectively movably arranged in different directions, which is specifically determined according to the actual situation and will not be elaborated here. During actual use of the rotating spraying component, since the spraying end of the rotating spraying component rotates around the central axis, the coolant can be evenly sprayed onto the corresponding heat dissipation area, and in the case where some spray holes of the rotating spraying component are blocked, due to the rotation of the spraying end around the central axis, the coolant can still be evenly sprayed onto the corresponding heat dissipation area, without affecting the heat dissipation effect of the heat-generating devices.

[0035] For the cabinet provided in this specific embodiment, since the spraying device includes a movable spraying assembly and a rotating spraying assembly, during actual use, the heat dissipation areas corresponding to the movable spraying assembly and the rotating spraying assembly can be reasonably allocated according to the different heat dissipation requirements of different positions of the heat-generating device. Specifically, the rotating spraying assembly can correspond to the heat dissipation area with higher heat dissipation requirements, and the movable spraying assembly can correspond to the heat dissipation area with lower heat dissipation requirements. In addition, when the temperature at a certain position in the heat dissipation area corresponding to the movable spraying assembly in the heat-generating device rises and the heat dissipation requirement increases, the movable spraying assembly can be controlled to move to the position corresponding to this area to spray the area with the increased temperature intensively, thereby improving the heat dissipation effect and meeting the heat dissipation requirements. When the temperature at a certain position in the heat dissipation area corresponding to the rotating spraying assembly in the heat-generating device rises and the heat dissipation requirement increases, the heat dissipation effect can be improved by increasing the spraying flow rate of the rotating spraying assembly to meet the heat dissipation requirements. Therefore, the technical problem of resource waste caused by using the same spraying intensity for heat-generating areas with different temperatures in the related art can be solved, and the technical effect of reasonably arranging the spraying assembly for heat-generating areas with different heat dissipation requirements and intensively dissipating heat for the areas with higher heat dissipation requirements can be achieved.

[0036] In a specific embodiment, the movable spraying assembly includes a movable pipeline 8, a plurality of first nozzles 10, and a driving mechanism 9. Among them, one end of the movable pipeline 8 is located in the liquid storage device 2, and the other end of the movable pipeline 8 extends out of the liquid storage device 2, and the length direction of the movable pipeline 8 located in the cabinet body 1 is arranged along the height direction of the cabinet body 1; a plurality of first nozzles 10 are installed in the part of the movable pipeline 8 located in the cabinet body 1, and the spraying direction of the first nozzles 10 faces the heat-generating device in the cabinet body 1; the driving mechanism 9 is installed in the liquid storage device 2 or the cabinet body 1, and the movable end of the driving mechanism 9 is connected to the movable spraying assembly to drive the movable spraying assembly to adjust the spraying position.

[0037] As Figure 1 shown, the number of the first nozzles 10 is multiple, 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 the heat-generating devices at different height positions in the cabinet body 1, so that different first nozzles 10 correspond to the heat-generating devices at different height positions.

[0038] During actual use, when the first nozzles 10 are installed, the installation angles of the first nozzles 10 can be adjusted so that the first nozzles 10 can spray to the required heat dissipation area. When the local temperature at a certain position of the heat-generating device rises, the driving mechanism 9 drives the movable pipeline 8 to move to the position where the first nozzles 10 can spray the area with the increased temperature, and sprays the coolant intensively on the area with the increased temperature to achieve key heat dissipation for the area with the increased temperature and meet the heat dissipation requirements when the local temperature of the heat-generating device rises.

[0039] In this specific embodiment, by setting the movable pipeline 8 and several first nozzles 10, during actual use, the driving mechanism 9 can drive the movable pipeline 8 to move, so as to adjust the spraying position of the first nozzles 10, meeting the purpose of focusing on heat dissipation at positions with higher heat dissipation requirements for heat-generating devices. In addition, in this specific embodiment, multiple first nozzles 10 can be arranged on the same movable pipeline 8, and during the movement of the movable pipeline 8, the spraying positions of the multiple first nozzles 10 can be adjusted.

[0040] On the basis of the above embodiment, the movable pipeline 8 can extend along the length direction of the cabinet body 1 inside the cabinet body 1. A plurality of 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 heat-generating devices at the same height position; during actual setting, corresponding movable pipelines 8 can be arranged for each layer of heat-generating devices, and any movable pipeline 8 can move independently. The moving direction of the movable pipeline 8 is along the length direction of the movable pipeline 8.

[0041] During actual use, when it is detected that the temperature of a local area in a certain layer of heat-generating devices in the cabinet body 1 is relatively high, the corresponding movable pipeline 8 of this heat-generating device can be adjusted to move along its length direction, so that the first nozzles 10 can focus on spraying the area with a higher temperature in the heat-generating device, meeting the heat dissipation requirements when the local temperature of the heat-generating device rises.

[0042] In this specific embodiment, the cabinet sets different movable pipelines 8 for heat-generating devices at different height positions. During actual use, the corresponding movable pipelines 8 can be adjusted for heat-generating devices at different height positions, avoiding the situation that the first nozzles 10 in the same movable pipeline 8 cannot take into account heat-generating devices at different height positions.

[0043] 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 limiting member 95; the mounting frame 91 is arranged outside the liquid storage device 2; the driving power member 92 is installed inside 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 in threaded cooperation with the lead screw 93; the threaded sleeve 94 is connected to the movable pipeline 8; the limiting member 95 is arranged at the end of the lead screw 93.

[0044] Such as Figure 2 、 Figure 3As shown in the figure, the installation frame 91 is fixedly installed on one side of the liquid storage device 2. The rear part of the inner cavity of the installation frame 91 is fixedly connected to the driving power component 92. The driving power component 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 component 92 is fixedly connected to the lead screw 93 through a coupling. The lead screw 93 can be set as a reciprocating lead screw. One end of the reciprocating lead screw is rotatably connected to the installation frame 91 through a bearing 282. A threaded sleeve 94 is slidably connected to the surface of the reciprocating lead screw. The surface of the threaded sleeve 94 is fixedly connected to the left moving pipe through a fixing block. A limit block is arranged at the end of the reciprocating lead screw. The setting of the limit block can effectively limit the moving range of the moving pipe and avoid the interference between the over-moving of the moving pipe and the rotary spraying assembly. When the lead screw 93 is a reciprocating lead screw, continuous spiral grooves are machined on the surface of the reciprocating lead screw, and internal threads matching the spiral grooves are machined in the inner hole of the threaded sleeve 94. The spiral grooves and the internal threads transmit motion and force through the sliding contact of the tooth surfaces of the threads. When the reciprocating lead screw rotates around its axis, the threaded sleeve 94 cannot rotate due to external constraints and is forced to make a linear reciprocating motion along the axis of the reciprocating lead screw. When the lead screw 93 is a common lead screw, external threads are arranged on the outer circumference of the lead screw 93, and internal threads matching the external threads are machined in the inner hole of the threaded sleeve 94. The threaded sleeve 94 and the lead screw 93 are connected through the external threads and the internal threads. When the lead screw 93 rotates around its axis, the threaded sleeve 94 cannot rotate due to external constraints and is forced to make a linear reciprocating motion along the axis of the lead screw 93.

[0045] During the actual use process, the driving power component 92 drives the reciprocating lead screw to rotate. During the rotation of the reciprocating lead screw, the moving pipe is driven by the threaded sleeve 94 to move along the axial direction of the reciprocating lead screw, realizing the adjustment of the spraying position of the first nozzle 10. When the temperature of a certain area in the heating device rises and the heat dissipation requirement increases, the driving power component 92 can be controlled to drive the reciprocating lead screw to rotate until the first nozzle 10 moves to the position for spraying the area with increased temperature and heat dissipation requirement. When the temperature of this area drops to the normal temperature, the driving power component 92 can be controlled to drive the reciprocating lead screw to rotate until the first nozzle 10 moves to the initial position.

[0046] In this specific embodiment, the mounting frame 91 is located outside the liquid storage device 2, achieving the physical separation of the drive mechanism 9 from the main body of the liquid storage device 2, simplifying the structural design and sealing requirements of the main body of the liquid storage device 2, and reducing the risk of internal contamination or leakage. Moreover, the entire drive mechanism 9 forms a relatively independent module, facilitating installation, commissioning, maintenance, and replacement without affecting the main body of the liquid storage device 2. Additionally, the cooperative transmission mode of the lead screw 93 and the threaded sleeve 94 can achieve small and precise displacement control. When the power is off or the drive stops, it can effectively maintain the position of the moving pipeline 8, preventing accidental movement caused by the load gravity or external force, being able to bear a large axial load, and having a relatively stable movement process with less impact and vibration. Furthermore, the limiting member 95 is arranged at the end of the lead screw 93. When the threaded sleeve 94 moves to the end of the lead screw 93, the limiting member 95 can effectively prevent it from continuing to move forward, preventing the lead screw 93 and the threaded sleeve 94 from disengaging or being damaged due to excessive movement. When the stroke limit is reached, the limiting member 95 can trigger the control system 31 to stop driving the power component 92, preventing the motor from being blocked and damaged or the mechanism from being overloaded and damaged.

[0047] Based on the above embodiment, as Figure 1 shown, the number of the moving pipelines 8 can be set to two, and the two moving pipelines 8 are respectively arranged on the opposite sides of the heating device, and the two moving pipelines 8 are driven to move by the same drive mechanism 9.

[0048] As Figure 3 shown, one of the moving pipelines 8 is connected to the threaded sleeve 94, and the other moving pipeline 8 is connected to this moving pipeline 8 through the connecting plate 17. As Figure 1 shown, the two moving pipelines 8 are respectively arranged on the opposite sides of the heating device. During actual use, the driving power component 92 can be driven to drive the reciprocating lead screw to rotate. During the rotation of the reciprocating lead screw, the moving pipe is driven to move along the axial direction of the reciprocating lead screw through the threaded sleeve 94, thereby driving the two moving pipelines 8 to move synchronously. During the movement of the two moving pipelines 8, the first nozzles 10 mounted thereon will be driven to move synchronously.

[0049] Of course, the number and layout position of the moving pipelines 8 can also be other solutions that meet the requirements, which are specifically determined according to the actual situation.

[0050] In this specific embodiment, the movement is driven by the same driving mechanism 9, which significantly simplifies the power system and the control system 31, reduces the hardware cost and system complexity, and at the same time ensures the synchronization of the movement of the two moving pipelines 8. In addition, the two moving pipelines 8 can spray on both sides of the heating device at the same time, covering the heat dissipation surface more evenly, eliminating the problem of excessive temperature on the side far from the spray side that may be caused by single-sided spraying; synchronous heat dissipation on both sides helps to maintain the balance of the overall temperature distribution of the device, preventing thermal stress concentration or local performance degradation caused by uneven heat dissipation. In addition, the impact, spreading and confluence of the spray fluids on both sides can form a more effective forced convection field, enhancing the disturbance and heat exchange intensity between the fluid and the device surface. Symmetrical spraying helps to reduce the flow dead zone formed on the back or corners of the device during single-sided spraying, making the heat dissipation more comprehensive; according to the spray angle design, the fluids on both sides may converge in the middle or a specific area of the device, further enhancing the heat exchange effect in this area.

[0051] In a specific embodiment, the first nozzle 10 can be rotatably arranged on the moving pipeline 8. During actual use, by adjusting the installation angle of the first nozzle 10 relative to the moving pipeline 8, the spraying angle of the first nozzle 10 can be adjusted.

[0052] The mobile spraying assembly can further include a first telescopic pipe. One end of the first telescopic pipe is connected to the moving pipeline 8, and the other end of the first telescopic pipe is connected to the first nozzle 10; the telescopic direction of the first telescopic pipe is perpendicular to both the extending direction and the moving direction of the moving pipeline 8.

[0053] During actual use, by adjusting the telescopic length of the first telescopic pipe, the position of the first nozzle 10 in the length direction of the first telescopic pipe can be adjusted, and then the spraying position of the first nozzle 10 in the length direction of the first telescopic pipe can be adjusted.

[0054] In this specific embodiment, by rotatably arranging the first nozzle 10 on the movable pipeline 8, after the types or models of the heating devices in the cabinet body 1 change, 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, so that the spraying angle of the first nozzle 10 can adapt to different heating devices, and a specific spraying heat dissipation solution for different heating devices can be realized. In addition, when there are multiple layers of heating devices in the cabinet body 1 and the types or models of the heating devices on different layers are different, the installation angles of the first nozzles 10 corresponding to the heating devices on different layers in the movable pipeline 8 can be adjusted respectively to adapt to the situation where the heat dissipation areas of the heating devices on different layers are different. In addition, by setting the first telescopic pipe, the position of the first nozzle 10 in the length direction of the first telescopic pipe can be adjusted. After the types or models of the heating devices in the cabinet body 1 change, the elongation distance of the first telescopic pipe corresponding to the corresponding layer can be adjusted to adjust the position of the first nozzle 10 in the length direction of the first telescopic pipe, so that the first nozzle 10 can adapt to the change of the required heat dissipation area in the length direction of the first telescopic pipe.

[0055] On the basis of the above embodiment, at least two movable spraying components can be set, and the moving directions of at least two movable spraying components are different.

[0056] Specifically, two movable spraying components can be set, one of the movable spraying components moves along Figure 2 the length direction of the cabinet body 1 in the middle, and the other movable spraying component moves along Figure 2 the width direction of the cabinet body 1 in the middle; in the actual use process, 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 this area with increased heat dissipation requirement, obtain the position information, and control one of the movable spraying components to move along the length direction of the cabinet body 1 to the heat dissipation position corresponding to this position information, and control the other movable spraying component to move along the width direction of the cabinet body 1 to the heat dissipation position corresponding to this position information, so that the two movable spraying components simultaneously dissipate heat from the area with increased heat dissipation requirement, improving the heat dissipation effect. Or, the heat dissipation areas responsible for the two movable spraying components can also be independent of each other. In the actual use process, 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 this area with increased heat dissipation requirement, obtain the position information, judge which movable spraying component's heat dissipation area this heat dissipation area belongs to according to the position information, and control the corresponding movable spraying component to move to the position corresponding to this position information to realize the heat dissipation of the area with increased heat dissipation requirement.

[0057] In this specific embodiment, at least two movable spray components are provided, and the spray components in different directions can cover different surfaces of the heating device or penetrate the complex internal structure of the device from different angles. A single-direction movable spray component may form a "heat dissipation blind area" at the concave part, leeward side or geometric dead corner of the device. Multi-directional collaborative spraying can ensure that the cooling medium covers the entire heat source surface without dead corners; the overlap of the movement trajectories can form a denser and more uniform "cooling grid" on the device surface, significantly improving the overall heat dissipation uniformity and avoiding local hot spots. In addition, for heating devices with irregular shapes, movable paths in different directions can be designed to precisely fit their contours to ensure the optimal spraying distance and angle. Furthermore, the jets from different directions can form an "impact flow" effect, generating intense turbulence in the intersection area and greatly enhancing the local heat transfer coefficient; the moving speed, flow rate or start / stop of each movable spray component can be independently controlled according to the real-time temperature of different regions of the device to preferentially cool the high-temperature regions and achieve intelligent thermal management.

[0058] In a specific embodiment, the rotating spray component includes a rotating main pipeline 26, a plurality of rotating branch pipelines 27 and a plurality of second nozzles 28. Among them, one end of the rotating main pipeline 26 is located in the liquid storage device 2, and the other end of the rotating main pipeline 26 extends from the liquid storage device 2 into the cabinet body 1, and the length direction of the rotating main pipeline 26 located in the cabinet body 1 is arranged along the height direction of the cabinet body 1; one end of the rotating branch pipeline 27 is connected to the part of the rotating main pipeline 26 located in the cabinet body 1, and the extending direction of the rotating branch pipeline 27 is perpendicular to the length direction of the rotating main pipeline 26; the second nozzle 28 is installed at the end of the rotating branch pipeline 27, and the spraying direction of the second nozzle 28 faces the heating device in the cabinet body 1; the second nozzle 28 is rotatably arranged around its central axis direction.

[0059] The rotating spray component in this specific embodiment is used to transfer the coolant in the liquid storage device 2 to the second nozzle 28 through the liquid guide pipe, so that the coolant is evenly sprayed on the surface of the heating device with high heat dissipation requirements. Here, the heating device 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 direction without external force. Therefore, when some spray holes are blocked, the blocked spray holes can be flushed open by increasing the flow rate without affecting the heat dissipation effect.

[0060] During actual use, as Figure 1 shown, the coolant in the liquid storage device 2 is sprayed out by the second nozzle 28 through the rotating main pipeline 26 and the rotating branch pipeline 27. The second nozzle 28 will rotate around its own central axis while spraying the coolant, and during the rotation, the spraying of the coolant on the surface of the heating device can be realized, thereby dissipating heat from the surface of the heating device.

[0061] In this specific embodiment, the rotating main pipeline 26 can be fixed on the inner side wall of the cabinet body 1 through Figure 1 the fastening clip 29 therein, only occupying the narrow space on the side of the cabinet body 1, and releasing more volume of the cabinet body 1 for electronic devices.

[0062] Since the second nozzle 28 in this specific embodiment can rotate around its own central axis, during actual use, generally the second nozzle 28 is used to dissipate heat from areas with higher heat dissipation requirements. During the rotation of the second nozzle 28, the uniformity of the coolant spraying can be improved, and at the same time, the heat dissipation effect can be enhanced.

[0063] The rotating branch pipeline 27 in this specific embodiment can be set as a rotating nozzle liquid guiding pipe made of metal material, and a valve can be additionally installed.

[0064] In this specific embodiment, the rotating main pipeline 26 runs through along the height direction of the cabinet to achieve longitudinal full coverage, and the rotating branch pipeline 27 radiates to both sides perpendicular to the main pipeline to form a transverse expansion, which can achieve a dead - angle - free coverage of the three - dimensional space inside the cabinet; in addition, the second nozzle 28 rotates around its axis, and the spraying flow can dynamically sweep the surface of the heating device to avoid local dry - burning areas of fixed spraying; furthermore, the rotation speed of the nozzle is dynamically adjusted according to the device temperature: it accelerates rotation in the high - temperature area to enhance heat dissipation and decelerates in the low - temperature area to save cooling capacity, effectively saving energy.

[0065] On the basis of the above - mentioned 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 buckle 281; wherein, the first end of the nozzle body is connected to the rotating branch pipeline 27; a variable - speed section and a Y - shaped frame 283 and a rotating fan 284 installed in the variable - speed section are arranged in the nozzle body, and the radial dimension of the cross - section of the variable - speed section is smaller than the radial dimension of other positions of the nozzle body; the second end of the nozzle body is provided with a spraying part 285 for spraying out the 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 buckle 281 is fixedly connected to the outer ring of the bearing 282, and the buckle 281 is connected to the rotating branch pipeline 27.

[0066] In this specific embodiment, the rotating fan 284 is suspended on the Y - shaped frame 283.

[0067] As Figure 4 shown, the buckle 281 is sleeved on the outer ring of the bearing 282, and at the same time, the buckle 281 is connected to the rotating branch pipeline 27 to realize the fixed installation of the second nozzle 28. As Figure 5 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, the rotating fan 284, and the spraying part 285 arranged in the nozzle body can all rotate synchronously with the nozzle body.

[0068] During actual use, the coolant enters the nozzle body through the first end of the nozzle body via the rotating branch pipeline 27. When the coolant flows through the variable-speed section, since the radial dimension of the cross-section of the variable-speed section decreases, the flow rate of the coolant in the variable-speed section increases, thereby driving the rotation of the rotating fan 284. The rotating fan 284, the Y-shaped frame 283, and the nozzle body are all of an integral structure. Therefore, during the rotation of the rotating fan 284, the nozzle body will be driven to rotate. During the rotation of the nozzle body, the spraying part 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 far from the first end.

[0069] 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 variable-speed section into three parts, further increasing the flow rate of the coolant flowing through the variable-speed section and increasing the rotation speeds of the rotating fan 284 and the spraying part 285.

[0070] In this specific embodiment, when the coolant flows through the variable-speed section with a suddenly reduced cross-section, according to Bernoulli's principle, the flow rate increases sharply, forming a high-speed jet impact on the rotating fan 284. More potential energy of the coolant will be converted into mechanical energy to drive the rotation of the rotating fan 284; the Y-shaped frame 283 located in the variable-speed section conducts tangential flow guidance on the fluid, forming a high-speed swirling flow impact on the fan blades, which can effectively increase the torque.

[0071] Based on the above embodiment, the second nozzle 28 can be rotatably arranged on the rotating branch pipeline 27. During actual use, by adjusting the installation angle of the second nozzle 28 relative to the rotating branch pipeline 27, the spraying angle of the second nozzle 28 can be adjusted.

[0072] The rotating spray assembly can further include a second telescopic pipe. One end of the second telescopic pipe is connected to the rotating branch pipeline 27, and the other end of the second telescopic pipe is connected to the second nozzle 28; the telescopic direction of the second telescopic pipe is along the central axis direction of the second nozzle 28.

[0073] During actual use, by adjusting the telescopic length of the second telescopic pipe, the position of the second nozzle 28 in the length direction of the second telescopic pipe can be adjusted, and the distance between the second nozzle 28 and the surface of the heating device can be adjusted.

[0074] In this specific embodiment, the second nozzle 28 is rotatably arranged on the rotating branch pipeline 27. After the types or models of the heat-generating devices in the cabinet body 1 change, 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 pipeline 27, so that the spraying angle of the second nozzle 28 can adapt to different heat-generating devices, realizing a specific spraying heat dissipation scheme for different heat-generating devices. In addition, when there are multiple layers of heat-generating devices in the cabinet body 1 and the types or models of the heat-generating devices in different layers are different, the installation angles of the second nozzles 28 corresponding to the heat-generating devices in different layers in the rotating branch pipeline 27 can be adjusted respectively to adapt to the situation where the heat dissipation areas of the heat-generating devices in different layers are different. In addition, by setting the second telescopic pipe, the position of the second nozzle 28 in the length direction of the second telescopic pipe can be adjusted. After the types or models of the heat-generating devices in the cabinet body 1 change, the elongation distance of the second telescopic pipe corresponding to the corresponding layer can be adjusted to adjust the distance between the second nozzle 28 and the surface of the corresponding heat-generating device, so that the second nozzle 28 can adapt to the change in the height direction size of the heat-generating device.

[0075] In a specific embodiment, the number of the rotating branch pipelines 27 is multiple, and the multiple rotating branch pipelines 27 are arranged at intervals along the length direction of the rotating main pipeline 26; and / or, one end of the rotating branch pipeline 27 connected to the rotating main pipeline 26 is rotatably arranged around the rotating main pipeline 26.

[0076] When there are multiple layers of heat-generating devices in the cabinet body 1, the multiple rotating branch pipelines 27 can be arranged at intervals along the length direction of the rotating main pipeline 26, so that different rotating branch pipelines 27 correspond to the heat-generating devices in different layers, so that all heat-generating devices have corresponding second nozzles 28 for spraying heat dissipation.

[0077] During actual use, when the positions of the high-requirement heat dissipation areas in the heat-generating devices in different layers are different, the rotation angle of the rotating branch pipeline 27 relative to the rotating main pipeline 26 can be adjusted to realize the adjustment of the heat dissipation area corresponding to the second nozzle 28 to adapt to the heat dissipation requirements of different heat-generating devices.

[0078] In this specific embodiment, one end of the rotating branch pipeline 27 connected to the rotating main pipeline 26 is rotatably arranged around the rotating main pipeline 26, breaking through the rigid limitation of traditional fixed spraying; the installation angle of the rotating branch pipeline 27 relative to the rotating main pipeline 26 can be adjusted according to the actual situation, which can be applicable to different heat-generating devices and meet diverse heat dissipation requirements.

[0079] In a specific embodiment, the mobile spraying assembly is provided with a first pressure sensor for detecting the spraying pressure; the rotating spraying assembly is provided with a second pressure sensor for detecting the spraying pressure.

[0080] 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 spraying assembly is in a normal working state; 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 there may be a blockage in the mobile spraying assembly, and the spraying flow rate is affected. At this time, the heat dissipation situation of the heating device 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 there is a relatively serious blockage in the mobile spraying assembly or the spraying flow rate is seriously insufficient. At this time, the normal heat dissipation of the heating device has been affected, and it is necessary to control the mobile spraying assembly to stop working and perform relevant repairs.

[0081] When the second pressure value detected by the second pressure sensor is less than the third preset pressure value, it indicates that the rotating spraying assembly is in a normal working state; 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 there may be a blockage in the rotating spraying assembly. However, since the spraying end of the rotating spraying assembly can rotate around its own central axis, it can still achieve uniform spraying of the heat dissipation area, and the influence on heat dissipation is relatively small. At this time, the spraying flow rate can be increased to observe whether the blocked spraying holes can be flushed open by increasing the spraying flow rate, and the heat dissipation situation of the heating device can be further observed, or relevant warning information can be issued; 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 there is a relatively serious blockage in the rotating spraying assembly or the spraying flow rate is seriously insufficient. At this time, the normal heat dissipation of the heating device has been affected, and it is necessary to control the rotating spraying assembly to stop working and perform relevant repairs.

[0082] In this specific embodiment, by setting the first pressure sensor on the mobile spraying assembly, the real-time monitoring of the spraying pressure of the spraying holes of the mobile spraying assembly can be realized, so as to conveniently obtain the spraying pressure information in a timely manner, and then make timely adjustments when the spraying pressure of the mobile spraying assembly does not meet the requirements, avoiding affecting the heat dissipation effect; the rotating spraying assembly is provided with a second pressure sensor for detecting the spraying pressure, which can realize the real-time monitoring of the spraying pressure of the spraying holes of the rotating spraying assembly, so as to conveniently obtain the spraying pressure information in a timely manner, and then make timely adjustments when the spraying pressure of the rotating spraying assembly does not meet the requirements, and flush open the spraying holes by adjusting the flow rate in the initial stage of the spraying pressure increase, avoiding affecting the heat dissipation effect.

[0083] On the basis of the above embodiments, a plurality of first temperature detectors may be provided in the cabinet body 1, and the first temperature detectors are used to detect the first temperature information at different positions of the heating device. And position information corresponds to each position where the first temperature detector is provided.

[0084] During actual use, first, it is necessary to obtain all the first temperature information detected by the plurality of first temperature detectors. Then, according to the obtained first temperature information, it is determined whether there is a warning temperature value exceeding the first preset temperature. If so, the position information of the first temperature detector corresponding to the warning temperature value is obtained, and according to the position information, it is determined whether the area detected by the first temperature detector belongs to the heat dissipation area corresponding to the mobile spray assembly or the heat dissipation area corresponding to the rotary spray assembly, or the area detected by the first temperature detector belongs to the overlapping area of the heat dissipation area corresponding to the mobile spray assembly and the heat dissipation area corresponding to the rotary spray assembly; when the area detected by the first temperature detector belongs to the heat dissipation area corresponding to the mobile spray assembly, the mobile spray assembly is controlled to move to the area corresponding to this position information for spraying; when the area detected by the first temperature detector belongs to the heat dissipation area corresponding to the rotary spray assembly, the rotary spray assembly is controlled to increase the spraying flow rate; when the area detected by the first temperature detector belongs to the overlapping area of the heat dissipation area corresponding to the mobile spray assembly and the heat dissipation area corresponding to the rotary spray assembly, the mobile spray assembly is controlled to move to the area corresponding to this position information for spraying while the rotary spray assembly is controlled to increase the spraying flow rate.

[0085] In this specific embodiment, by providing a plurality of first temperature detectors at different positions of the heating device, during actual use, the temperature information at different positions of the heating device can be obtained in real time. When the temperature of a certain area of the heating device rises and the heat dissipation requirement increases, the mobile spray assembly or the rotary spray assembly can be timely controlled to make relevant adjustments, so as to implement a corresponding heat dissipation solution for different heat dissipation requirement areas in the heating device, meet the heat dissipation requirements and reduce the waste of energy at the same time.

[0086] 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 provided on the liquid storage box body; a water pumping power member 4 and a transfer pipe 6 are provided in the liquid storage box body. The first end of the transfer pipe 6 is connected to the water pumping power member 4, the second end of the transfer pipe 6 is connected to the mobile spray assembly, and the third end of the transfer pipe 6 is connected to the rotary spray assembly; the parts of the mobile spray assembly and the rotary spray assembly used for connecting to the transfer pipe 6 are all deformable hoses.

[0087] The liquid storage device 2 in this specific embodiment is used to discharge the coolant with a higher temperature in the liquid storage box body and introduce low-temperature coolant, enhance the heat dissipation effect, and on the other hand, provide coolant for the entire cabinet.

[0088] To avoid the situation of uneven temperature of the coolant in the liquid storage device 2, as Figure 2 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.

[0089] As Figure 1 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 a liquid outlet pipe 5, and the other end of the liquid outlet pipe 5 is connected with a transfer pipe 6. Two interfaces are provided at the second end of the transfer pipe 6, which are respectively connected to two first hoses 7. The other ends of the two first hoses 7 are respectively connected to two movable pipelines 8, and the movable pipelines 8 can be made of metal; the third end of the transfer pipe 6 is connected to one end of a second hose 25, and the other end of the second hose 25 is connected to a rotating main pipeline 26 made of metal.

[0090] As Figure 1 shown, the two first hoses 7 are symmetrically arranged with respect to the middle section of the cabinet body 1. The second hose 25 is provided with a bend and is located below the first hose 7. During actual use, when the movable pipeline 8 is driven by the driving mechanism 9 to move, the set position of the second hose 25 effectively avoids the first hose 7, and interference between the first hose 7 and the second hose 25 can be avoided.

[0091] In this specific embodiment, both the movable spraying assembly and the rotating spraying assembly are connected to the water pumping power component 4 through hoses. During actual use, when the movable spraying assembly moves, the hose connecting the movable spraying assembly and the water pumping power component 4 deforms, so that the movable spraying assembly has a sufficient moving stroke to meet the moving requirements of the movable spraying assembly. In addition, the rotating spraying assembly is connected to the water pumping power component 4 through a hose. When the rotating spraying assembly is displaced or vibrates, the connection part can be effectively prevented from being damaged, and the connection reliability is improved.

[0092] On the basis of the above embodiments, a second temperature detection component for detecting the temperature of the coolant, a liquid level sensor for detecting the liquid level height in the liquid storage box body, and a water quality detection mechanism for detecting the quality of the coolant in the liquid storage box body can be provided in the liquid storage box body.

[0093] During actual use, when the second temperature detection component detects that the temperature of the coolant in the liquid storage device 2 is higher than the preset temperature value, coolant with a lower temperature can be input through the liquid inlet hole 2B, and the coolant with a higher temperature can be discharged through the liquid outlet hole 2A, so that the temperature of the coolant in the liquid storage device 2 meets the requirements. When the liquid level sensor detects that the liquid level of the coolant in the liquid storage device 2 is lower than the minimum liquid level standard, the liquid inlet hole 2B is controlled to input coolant. When the liquid level sensor detects that the liquid level of the coolant in the liquid storage device 2 is higher than or reaches the maximum liquid level standard, the liquid inlet hole 2B is controlled to stop inputting coolant, or the liquid outlet hole 2A is controlled to discharge coolant.

[0094] The water quality detection mechanism may include a conductivity sensor and a pH detection component. The conductivity sensor is mainly used to detect ionic contamination, and the pH detection component 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 specifically determined according to the actual situation.

[0095] In this specific embodiment, the second temperature detection component can monitor the core temperature of the coolant in the liquid storage tank in real time, which is beneficial to realizing dynamic adjustment of the coolant temperature. The liquid level sensor can monitor the liquid level of the coolant in the liquid storage tank in real time, facilitating timely replenishment of the coolant. In addition, the water quality detection mechanism monitors the quality of the coolant in the liquid storage tank. When the quality of the coolant does not meet the requirements, the coolant can be replaced in time or relevant treatments can be made.

[0096] In a specific embodiment, the cabinet further includes a filtering device 3. The filtering device 3 includes a filtering box body and a filtering plate 12 arranged in the filtering box body. 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 filtering plate 12.

[0097] The filtering device 3 is mainly used to clean the coolant, thereby reducing the risk of blockage of the spray holes and the liquid guiding pipes. As Figure 9 shown, rectangular slots 23 adapted to the moving pipeline 8 and the rotating main pipeline 26 are respectively opened on both sides of the top of the filtering device 3. As Figure 1 shown, a guiding slot 22 is arranged on the side surface of the cabinet body 1. During actual installation, both the moving pipeline 8 and the rotating main pipeline 26 extend into the cabinet body 1 through the guiding slot 22 and the rectangular slot 23. The rotating main pipeline 26 is at the forefront of the rectangular slot 23, and the moving pipeline 8 reciprocates in other spaces of the rectangular slot 23. A limiting member 95 is provided at the end of the lead screw 93 away from the driving power member 92 to prevent the moving pipeline 8 and the rotating main pipeline 26 from interfering with each other.

[0098] In this specific embodiment, by providing a filtering device 3, the coolant flowing back into the liquid storage device 2 can be filtered to prevent impurities from entering the liquid storage device 2, effectively avoiding pipeline blockage. Additionally, the filtering device 3 is arranged between the cabinet body 1 and the liquid storage device 2, which can effectively and reasonably utilize the space. The coolant sprayed by the spraying device can flow through the filtering device 3 under the action of gravity and then flow back into the liquid storage device 2, achieving effective utilization of the space.

[0099] Based on the above embodiment, a sliding groove 11 can be provided on the side wall of the filtering box body. An end limiting component is arranged outside the sliding groove 11. The filter plate 12 is detachably inserted into the sliding groove 11. The end limiting component includes an end limiting plate 14 and an end limiting screw 15 passing through the end limiting plate 14 and rotatable relative to the end limiting plate 14. A limiting screw hole 16 for cooperating with the end limiting screw 15 is provided on the part of the filter plate 12 extending out of the sliding groove 11.

[0100] As Figure 9 shown, a sliding groove 11 is opened at the front part of the filtering box body. A filter plate 12 is arranged inside the sliding groove 11. A limiting groove 13 adapted to the filter plate 12 is opened at the rear part of the inner cavity of the filtering box body. An end limiting plate 14 is fixedly connected to the front part of the filtering box body and in front of the sliding groove 11. The top of the end limiting plate 14 is slidably connected to the filtering box body through an opening. A limiting screw hole 16 adapted to the end limiting screw 15 is opened at the top of the filter plate 12. By rotating the end limiting screw 15 to move out of the limiting screw hole 16, the filter plate 12 can be regularly pulled out and disassembled from the filtering box body for cleaning.

[0101] In this specific embodiment, by providing an end limiting component, the installation position of the filter plate 12 can be fixed, and the filter plate 12 can be disassembled. The detachable setting method of the filter plate 12 is convenient for taking 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.

[0102] Based on the above embodiment, the moving spraying component is provided with a connecting piece facing the filter plate 12 and a cleaning brush 19 at the end of the connecting piece. The cleaning brush 19 is in contact with the filter plate 12. The moving spraying component drives the cleaning brush 19 to move relative to the filter plate 12 to clean the filter plate 12.

[0103] As Figure 3 shown, the connecting piece includes a connecting plate 17 for connecting two moving pipelines 8 and a connecting block 18 with one end connected to the connecting plate 17 and the other end connected to the cleaning brush 19. During actual use, when the moving spraying component is driven by the driving mechanism 9 to move, the cleaning brush 19 will move relative to the filter plate 12 to clean the filter plate 12.

[0104] In this specific embodiment, the movement of the movable spraying assembly drives the cleaning brush 19 to move relative to the filter plate 12, realizing the cleaning of the filter plate 12. The structure is compact, and there is no need to additionally set a power structure for driving the cleaning brush 19 to move, which can effectively reduce the number of components and lower the cost.

[0105] In a specific embodiment, as Figure 1 shown, a tray 24 for carrying heat-generating devices is provided in the cabinet body 1; a plurality of liquid discharge holes 21 are provided at the bottom of the tray 24, and a first baffle that is completely enclosed in the circumferential direction is provided on the outer peripheral side surface of the tray 24, and the protruding height of the first baffle is higher than the height of the surface of the tray 24 for carrying heat-generating devices.

[0106] As Figure 10 shown, the tray 24 is fixed to the cabinet body 1 through four lugs 20.

[0107] 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 both ends; along the width direction of the cabinet body 1, second baffles are provided on both sides of the liquid guide plate 30, and the protruding height of the second baffles is higher than the height of the highest position of the bottom surface of the liquid guide plate 30.

[0108] The cabinet body 1 is located above the filtering device 3, and the heat-generating device is located on the tray 24 of the cabinet body 1. During actual use, an insulating coolant can be used. To avoid corrosion caused by the long-term contact between the coolant and the heat-generating device, an insulating material can be coated on the surface of the heat-generating device, which will not affect heat dissipation. Here, the heat-generating device can be a server system without a chassis.

[0109] During actual use, the heat-generating device is placed in the tray 24, and the coolant sprayed by the spraying device flows through the surface of the heat-generating device and then converges into the tray 24, and is discharged from the liquid discharge holes 21 of the tray 24 to the liquid guide plate 30. In this specific embodiment, a first baffle that is completely enclosed in the circumferential direction is provided on the outer peripheral side surface of the tray. When the flow rate of the coolant sprayed by the spraying device is relatively large, a certain height of coolant can be temporarily stored in the tray 24, and it can ensure that the coolant in the tray 24 is constantly updated, further enhancing the heat dissipation effect.

[0110] In addition, in this specific embodiment, along the length direction of the cabinet body 1, the middle of the liquid guide plate 30 is high and both sides are low, which can make the coolant flow out from the middle of the liquid guide plate 30 to both sides. And along the width direction of the cabinet body 1, second baffles are provided on both sides of the liquid guide plate 30, which can prevent the coolant from flowing out of the cabinet body 1, so that the coolant flows back to the filtering device 3 according to the guiding of the liquid guide plate 30, and finally flows back to the liquid storage device 2.

[0111] In addition to the above-mentioned cabinet, the present application also provides a control method applied to the above-mentioned cabinet. A plurality of first temperature detection components are arranged in the cabinet body 1 of the cabinet. The first temperature detection components are used to detect the first temperature information at different positions of the heating equipment. The control method includes: Step S1, obtaining the first temperature information detected by all the first temperature detection components.

[0112] Step S2, judging whether there is a warning temperature value exceeding the 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.

[0113] Step S3, judging whether the position information belongs to the spraying area of the mobile spraying component. If so, controlling the mobile spraying component to move to the area corresponding to the position information for spraying; if not, controlling the rotating spraying component to increase the spraying flow rate.

[0114] In this specific embodiment, by setting the first temperature detection component, the first temperature information at different positions of the heating equipment can be obtained in real time. When the first temperature information is higher than the warning temperature value, the mobile spraying component can be timely controlled to spray and dissipate heat on this area emphatically, or the rotating spraying device can be controlled to increase the spraying flow rate, so as to implement different heat dissipation schemes for different positions with different heat dissipation requirements in the heating equipment, focus on spraying in the area with higher heat dissipation requirements, and effectively reduce energy consumption while ensuring the heat dissipation effect.

[0115] In addition to the above-mentioned cabinet, the present application also provides a control method applied to the above-mentioned cabinet. The mobile spraying component is provided with a first pressure sensor for detecting the spraying pressure and a first warning device; the rotating spraying component is provided with a second pressure sensor for detecting the spraying pressure and a second warning device; the control method includes: Step S01, obtaining the first pressure value detected by the first pressure sensor and the second pressure value detected by the second pressure sensor.

[0116] Step S02, judging whether the first pressure value is greater than the first preset pressure value. If so, controlling the first warning device to send a warning message and entering step S03; if not, returning to step S01.

[0117] Step S03, judging 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 spraying component to stop working, if not, maintaining the current working state of the mobile spraying component.

[0118] Step S04, judging whether the second pressure value is greater than the third preset pressure value. If so, controlling the second warning device to send a warning message, controlling to increase the flow rate of the rotating spraying component, and entering step S05; if not, returning to step S03.

[0119] In step S05, it is determined whether the second pressure value is greater than the fourth preset pressure value, and the fourth preset pressure value is greater than the third preset pressure value; if so, the rotary spray assembly is controlled to stop working, and if not, the current working state of the rotary spray assembly is maintained.

[0120] In this specific embodiment, by setting the first pressure sensor and the first warning device, the injection pressure of the spray holes of the mobile spray assembly can be monitored in real time, so as to facilitate timely acquisition of the spray pressure information, and then make timely adjustments when the injection pressure of the mobile spray assembly does not meet the requirements, avoiding affecting the heat dissipation effect; the rotary spray assembly is provided with a second pressure sensor for detecting the injection pressure, which can realize the real-time monitoring of the injection pressure of the spray holes of the rotary spray assembly, so as to facilitate timely acquisition of the spray pressure information, and then make timely adjustments when the injection pressure of the rotary spray assembly does not meet the requirements, and flush the spray holes by adjusting the flow rate in the initial stage of the spray pressure increase, avoiding affecting the heat dissipation effect.

[0121] In addition to the above cabinet, the present application also provides a control method applied to the above cabinet.
