Description

Technical Field

[0001] The present invention belongs to the technical field of electronic equipment heat dissipation, and in particular relates to a liquid cooling door device for auxiliary heat dissipation of a server cabinet. Background Art

[0002] Server cabinets play a vital role in data centers. They are responsible for accommodating and cooling key equipment such as servers. As server performance continues to improve, the heat generated by them also increases, which requires the cabinet cooling system to be more efficient. Existing cooling technologies mainly include air cooling and liquid cooling.

[0003] Among them, the liquid cooling system absorbs heat through circulating liquid and has higher heat dissipation efficiency, but the traditional liquid cooling system usually requires a complex liquid cooling pipeline layout and a large space occupancy, and the difficulty and cost of installation and maintenance are relatively high. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a liquid cooling door device for auxiliary heat dissipation of a server cabinet, so as to solve the problems of complex layout of liquid cooling pipes and large space occupied in the liquid cooling system in the prior art, as well as the relatively high difficulty and cost of installation and maintenance.

[0005] One of the schemes of the present invention provides a liquid cooling door device for auxiliary heat dissipation of a server cabinet, comprising a base plate installed at an air outlet of the server cabinet, the base plate comprising a fixed partition and a movable door, a liquid cooling cavity is provided between the fixed partition and the movable door, a liquid cooling adjustment component is installed in the liquid cooling cavity, the liquid cooling adjustment component comprises a liquid cooling component and an adjustment component, the liquid cooling component is detachably connected to the fixed partition; the adjustment component comprises a temperature sensing module, a liquid leakage detection module and a control component;

[0006] The liquid cooling component comprises a liquid inlet pipe and a liquid outlet pipe, the liquid inlet pipe is connected with the liquid outlet pipe, and the connecting part of the liquid inlet pipe and the liquid outlet pipe extends from the fixed partition plate to the air outlet of the server cabinet, and the liquid inlet pipe and the liquid outlet pipe are connected to a cold source externally;

[0007] The liquid cooling component is used to adjust the working state according to the instruction of the regulating component to control the external cold source to enter the liquid cooling component, thereby assisting the heat dissipation of the server cabinet;

[0008] The temperature sensing module is used to obtain the temperature of the air outlet of the server cabinet and convert it into a temperature signal to transmit to the control component;

[0009] The liquid leakage detection module is used to detect whether there is leakage in the liquid inlet pipe and the liquid outlet pipe, and convert the leakage into a liquid leakage signal and transmit it to the control component;

[0010] The control component is used to receive and process the temperature signal and the liquid leakage signal to control the operation of the liquid cooling component;

[0011] It should be noted that, in actual use, the temperature sensing module and the leakage detection module are both provided with corresponding sensors to obtain the ambient temperature and the pipeline leakage respectively. The control component is internally provided with corresponding signal transceivers, processors, controllers and working equipment. The signal transceivers and processors can receive and process temperature signals and leakage signals, convert them into working signals and output them to the liquid cooling components, thereby controlling the working state of the liquid cooling components; wherein, the leakage sensor in the leakage detection module can be specifically a pressure sensor, which detects the pressure inside the hose to realize leakage detection; the cold source starts from the cold source in the form of coolant, flows through the liquid inlet pipe and the liquid outlet pipe, and then flows back to the cold source;

[0012] It should be additionally explained that the connecting portion of the liquid inlet pipe and the liquid outlet pipe in the liquid cooling component specifically extends from the fixed partition plate toward the air outlet of the server cabinet, and the cooling liquid flowing through the connecting portion exchanges heat with the hot air emitted from the air outlet of the server cabinet, thereby achieving the effect of assisting the heat dissipation of the server cabinet; the liquid cooling component is detachably connected to the fixed partition plate, specifically by providing a hole on the fixed partition plate for the liquid inlet pipe and the liquid outlet pipe to extend therethrough, and providing a detachable connector of the same type as a hose clamp on the corresponding hole of the liquid outlet pipe, so that when the staff needs to perform routine maintenance or replacement of the liquid cooling component, the detachable connector at the infusion pipe can be directly removed to separate the liquid cooling component as a whole from the fixed partition plate;

[0013] In addition, the liquid cooling component at least includes a start-stop device for controlling the input of the cold source. The start-stop device can be a liquid pump. In actual use, the start-stop device is controlled by the control component, and controls the input of the coolant in the cold source according to the working signal output by the control component, that is, the coolant is input through the start-stop device through a continuous cycle, and flows through the liquid inlet pipe and the liquid outlet pipe in sequence, and finally returns to the cold source, so as to assist the heat dissipation of the server;

[0014] Specifically, when the server is working, the server dissipates hot air through the air outlet on the server cabinet to achieve the purpose of heat dissipation, and the liquid cooling adjustment component is also in a working state. The temperature sensing module and the leakage detection module start to continuously obtain the ambient temperature and pipeline leakage respectively, and convert them into temperature signals and leakage signals to transmit to the control component. The control component receives and processes the temperature signal and leakage signal, and finally converts them into working signals and outputs them to the liquid cooling component to control the output power of the start-stop device in the liquid cooling component, thereby controlling the flow of the coolant at the liquid inlet pipeline and the liquid outlet pipeline to control the auxiliary heat dissipation effect;

[0015] More specifically, the control component is preset with a standard temperature of the air outlet of the server cabinet. When receiving and processing the temperature signal and the leakage signal, the control component first determines the leakage state of the liquid inlet pipe and the liquid outlet pipe according to the obtained leakage signal. If it is in a leakage state, a corresponding working signal is directly sent to the start-stop device to control the start-stop device to stop the delivery of the coolant. If it is not in a leakage state, the temperature value corresponding to the leakage signal is further obtained. When the temperature value is lower than the standard temperature of the air outlet of the server cabinet, the control component sends a corresponding working signal to the start-stop device to reduce the delivery flow of the coolant. When the temperature value is lower than the standard temperature of the air outlet of the server cabinet, the delivery flow of the coolant is increased.

[0016] Since the base plate in the liquid cooling adjustment component is installed at the air outlet of the cabinet, when the hot air is continuously dissipated from the air outlet of the cabinet, the hot air continues to pass through the liquid inlet pipe and the liquid outlet pipe in the liquid cooling component. When the continuously circulating coolant flows through the liquid inlet pipe and the liquid outlet pipe, the coolant continuously exchanges heat with the hot air through the liquid inlet pipe and the liquid outlet pipe to absorb the heat in the hot air, and circulates back to the cold source from the liquid outlet pipe to achieve the effect of assisting the heat dissipation of the server cabinet.

[0017] It should be noted that in actual use, the staff can increase the number of liquid inlet pipes and liquid outlet pipes according to the actual auxiliary cooling needs, and then increase the number of connecting parts, or increase the diameter of the connecting parts of the liquid inlet pipes and liquid outlet pipes, so as to enhance the overall auxiliary cooling effect by increasing the heat transfer area.

[0018] In this solution, by extending the connecting part of the liquid inlet pipe and the liquid outlet pipe in the liquid cooling component, and using the cooling liquid circulating in the liquid inlet pipe and the liquid outlet pipe to perform heat exchange with the hot air blown to the connecting part of the liquid inlet pipe and the liquid outlet pipe at the air outlet of the server cabinet, the heat at the air outlet of the server cabinet can be taken away, and the effect of assisting the heat dissipation of the server is achieved with a simple liquid cooling pipe layout and a small occupied space;

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The liquid cooling pipeline layout designed by the present invention is simple. By arranging the liquid cooling component on the fixed partition, and extending the connecting part of the liquid inlet pipeline and the liquid outlet pipeline in the liquid cooling component to the air outlet of the server cabinet, the effect of assisting the heat dissipation of the server is achieved with a simple liquid cooling pipeline layout and a small occupied space;

[0021] 2. The liquid cooling component designed in the present invention has a relatively low cost and can be directly disassembled as a whole from the fixed partition, which is convenient for workers to install, perform routine maintenance and replace the liquid cooling components, thereby improving the installation and maintenance work efficiency of workers and reducing installation and maintenance costs;

[0022] 3. The regulating component designed in the present invention can, on the one hand, adaptively adjust the coolant flow rate of the connecting part of the liquid inlet pipe and the liquid outlet pipe according to the temperature of the air outlet of the server cabinet, so as to adaptively adjust the cooling effect to avoid the situation where the temperature at the air outlet is too low or too high, which may affect the server. On the other hand, it can control the start and stop of the start-stop device according to the leakage of the liquid inlet pipe and the liquid outlet pipe in the liquid cooling component to prevent the cold source from continuously passing the coolant when leakage occurs, resulting in the accumulation of coolant in the server cabinet.

[0023] In one of the solutions, the liquid outlet pipe is connected to a storage branch pipe, a suction pump is installed on the storage branch pipe, the storage branch pipe is connected to a reservoir, and the suction pump is electrically connected to the control component.

[0024] It should be noted that the suction pump can receive a working signal from the control component and work according to the corresponding working signal;

[0025] Specifically, when the leakage signal obtained by the control component determines that the liquid inlet pipe and the liquid outlet pipe are in a leakage state, and sends a working signal to the start-stop device to control the start-stop device to stop the delivery of the coolant, synchronously, the control component sends a working signal to the suction pump to control the suction pump to work briefly. The specific working time is 1-2 seconds. The suction pump can quickly absorb the remaining coolant in the liquid outlet pipe into the storage branch pipe during the working time, so as to avoid the coolant flowing out of the liquid outlet pipe during subsequent maintenance or replacement of liquid cooling components by the staff.

[0026] In this solution, through the storage branch pipe and the suction pump electrically connected to the control component, the remaining coolant in the liquid outlet pipe can be quickly sucked into the storage branch pipe when the liquid cooling component leaks, thereby reducing the situation where the coolant flows out of the liquid cooling component when the subsequent staff maintains or replaces the liquid cooling component.

[0027] In one of the solutions, a delivery branch pipe is connected between the liquid inlet pipe and the liquid outlet pipe, an isolation valve is installed at one end of the delivery branch pipe connected to the liquid inlet pipe, and the isolation valve is electrically connected to the control component.

[0028] It should be noted that the isolation valve is capable of receiving a working signal from the control component and operates according to the corresponding working signal;

[0029] Specifically, when the leakage signal obtained by the control component determines that the liquid inlet pipeline and the liquid outlet pipeline are in a leakage state, and sends a working signal to the start-stop device to control the start-stop device to stop the delivery of the coolant, the synchronous control component sends a working signal to the isolation valve to control the isolation valve to close, thereby isolating the liquid inlet pipeline and the delivery branch, thereby achieving the effect of stopping the delivery of coolant to the delivery branch where the leakage occurs.

[0030] In this solution, through the delivery branch pipe and the isolation valve electrically connected to the control component, the coolant in the liquid inlet pipe can be isolated from the delivery branch pipe when leakage occurs in the liquid cooling component, thereby achieving the effect of stopping the delivery of coolant to the delivery branch pipe where the leakage occurs.

[0031] In one of the solutions, the other end of the delivery branch pipe is connected to the liquid outlet pipe through an intermediate piece.

[0032] In one of the solutions, a plurality of liquid cooling grooves are provided on the fixed partition plate, and the delivery branch pipe is connected to the liquid inlet pipe and the liquid outlet pipe through the plurality of liquid cooling grooves.

[0033] It should be noted that the intermediate piece can be a detachable connector of the same type as a hose clamp, so that when the staff needs to perform routine maintenance or replacement of the liquid cooling component, they can directly separate the delivery branch pipe from the liquid outlet pipe by disassembling the detachable connector at the infusion pipe;

[0034] It should be additionally explained that the two ends of the delivery branch pipe pass through two liquid cooling grooves respectively to be connected to the liquid inlet pipe and the liquid outlet pipe respectively, which can play a role of limiting support for the delivery branch pipe to prevent the delivery branch pipe from sagging under the action of gravity, thereby affecting the auxiliary cooling effect.

[0035] In one of the solutions, a sliding groove is provided inside the fixed partition, the sliding groove is located below the liquid cooling groove, and a blocking member is slidably connected inside the sliding groove.

[0036] It should be noted that the blocking member is adapted to the liquid cooling groove, and the blocking member is used to limit and fasten the delivery branch pipe in the liquid cooling groove.

[0037] In this solution, through the cooperation of the sliding groove and the blocking member, on the one hand, the blocking member can slide in the sliding groove to limit and tighten the delivery branch pipe in the liquid cooling groove; on the other hand, it can prevent the hot air emitted from the air outlet of the server cabinet from blowing from the liquid cooling groove to the liquid cooling component and affecting the working state of the liquid cooling component.

[0038] In one of the schemes, at least two delivery branches are provided, a temperature sensor is provided at the connection end between the delivery branch and the liquid outlet pipe, flow distributors are installed on the two delivery branches, the temperature sensor is connected to the flow distributor, and the flow distributor is electrically connected to the control component.

[0039] It should be noted that a temperature sensor is installed at the connecting end of the delivery branch pipe and the liquid outlet pipe. The temperature sensor can obtain the temperature information of the connecting end of the delivery branch pipe and the liquid outlet pipe and feed it back to the flow distributor. The flow distributor transmits the temperature information to the control component, and then the control component controls the coolant flow rate of each delivery branch in the flow distributor according to the temperature information, that is, reduces the coolant flow rate of the delivery branch with a temperature lower than the standard temperature, and increases the coolant flow rate of the delivery branch with a temperature higher than the standard temperature, so as to improve the cooling efficiency of the overall cooling components.

[0040] In this solution, by means of at least two delivery branches, a temperature sensor and a flow distributor electrically connected to the control component, the coolant flow in each delivery branch can be controlled according to the temperature of each delivery branch to improve the cooling efficiency of the overall cooling component.

[0041] In one of the solutions, the movable door is movably connected to the base plate via a connecting member.

[0042] In one of the schemes, an inclined bracket is also installed inside the liquid cooling chamber, the liquid cooling adjustment assembly is installed on the inclined bracket, one end of the inclined bracket is connected to the movable door, and the other end is located at the bottom of the liquid cooling chamber, and the connecting piece is located at the bottom of the movable door.

[0043] In this solution, through the cooperation of the connecting parts and the tilt bracket, the baseboard can be taken out as a whole by opening the movable door, and then the liquid cooling adjustment components inside the server cabinet or the baseboard can be maintained or replaced daily, thereby improving the work efficiency of the staff in installation or daily maintenance.

[0044] In one of the solutions, a horizontal guide rail is also installed at the bottom of the liquid cooling chamber, the liquid cooling adjustment assembly is movably connected to the horizontal guide rail, and the connecting piece is located on the side of the movable door.

[0045] In this solution, through the cooperation of the connecting parts and the horizontal guide rails, the movable door can be opened and the entire baseboard can be taken out horizontally from the liquid cooling chamber, and then the liquid cooling adjustment components inside the server cabinet or the baseboard can be maintained or replaced daily, thereby improving the work efficiency of the staff in installation or daily maintenance.

[0056] Please refer to Figure 1-4 One embodiment of the present invention provides a liquid cooling door device for auxiliary heat dissipation of a server cabinet, comprising a base plate 1 installed at an air outlet of the server cabinet, the base plate 1 comprising a fixed partition plate 2 and a movable door 3, a liquid cooling cavity 4 is provided between the fixed partition plate 2 and the movable door 3, a liquid cooling adjustment component is installed in the liquid cooling cavity 4, the liquid cooling adjustment component comprises a liquid cooling component and an adjustment component 44, the liquid cooling component is detachably connected to the fixed partition plate 2; the adjustment component 44 comprises a temperature sensing module, a liquid leakage detection module and a control component;

[0057] The liquid cooling component includes a liquid inlet pipe 41 and a liquid outlet pipe 42, the liquid inlet pipe 41 is connected to the liquid outlet pipe 42, and the connecting portion of the liquid inlet pipe 41 and the liquid outlet pipe 42 extends from the fixed partition 2 to the air outlet of the server cabinet, and the liquid inlet pipe 41 and the liquid outlet pipe 42 are connected to a cold source externally;

[0058] The liquid cooling component is used to adjust the working state according to the instruction of the regulating component 44, so as to control the external cold source to enter the liquid cooling component, thereby assisting the heat dissipation of the server cabinet;

[0059] The temperature sensing module is used to obtain the temperature of the air outlet of the server cabinet and convert it into a temperature signal to transmit to the control component;

[0060] The liquid leakage detection module is used to detect whether there is leakage in the liquid inlet pipe 41 and the liquid outlet pipe 42, and convert the leakage into a liquid leakage signal and transmit it to the control component;

[0061] The control component is used to receive and process the temperature signal and the liquid leakage signal to control the operation of the liquid cooling component;

[0062] It should be noted that, in actual use, the temperature sensing module and the leakage detection module are both provided with corresponding sensors to obtain the ambient temperature and the pipeline leakage respectively, and the control component is provided with corresponding signal transceivers, processors, controllers and working equipment. The signal transceivers and processors can receive and process temperature signals and leakage signals, convert them into working signals and output them to the liquid cooling components, thereby controlling the working state of the liquid cooling components; the cold source starts from the cold source in the form of coolant, flows through the liquid inlet pipe 41 and the liquid outlet pipe 42, and then flows back to the cold source;

[0063] It should be additionally explained that the connecting portion of the liquid inlet pipe 41 and the liquid outlet pipe 42 in the liquid cooling component specifically extends from the fixed partition 2 toward the air outlet of the server cabinet, and the cooling liquid flowing through the connecting portion exchanges heat with the hot air emitted from the air outlet of the server cabinet, thereby achieving the effect of assisting the heat dissipation of the server cabinet; the liquid cooling component is detachably connected to the fixed partition 2, specifically by providing a hole on the fixed partition 2 for the liquid inlet pipe 41 and the liquid outlet pipe 42 to extend, and providing a detachable connector 31 of the same type as a hose clamp on the corresponding hole of the liquid outlet pipe 42, so that when the staff needs to perform daily maintenance or replacement of the liquid cooling component, the detachable connector 31 at the infusion pipe can be directly removed to separate the liquid cooling component as a whole from the fixed partition 2;

[0064] In addition, the liquid cooling component at least includes a start-stop device for controlling the input of the cold source. The start-stop device can be a liquid pump. In actual use, the start-stop device is controlled by the control component, and controls the input of the coolant in the cold source according to the working signal output by the control component, that is, the coolant is input through the start-stop device through a continuous cycle, and flows through the liquid inlet pipe 41 and the liquid outlet pipe 42 in sequence, and finally returns to the cold source, so as to assist the server in heat dissipation;

[0065] Specifically, when the server is working, the server dissipates hot air through the air outlet on the server cabinet to achieve the purpose of heat dissipation, and the liquid cooling adjustment component is also in working state, the temperature sensing module and the leakage detection module start to continuously obtain the ambient temperature and pipeline leakage respectively, and convert them into temperature signals and leakage signals to transmit to the control component, the control component receives and processes the temperature signal and leakage signal, and finally converts them into working signals and outputs them to the liquid cooling component to control the output power of the start-stop device in the liquid cooling component, and then controls the flow of the coolant at the liquid inlet pipe 41 and the liquid outlet pipe 42 to control the auxiliary heat dissipation effect;

[0066] More specifically, the control component is preset with a standard temperature of the air outlet of the server cabinet. When receiving and processing the temperature signal and the leakage signal, the control component first determines the leakage state of the liquid inlet pipe 41 and the liquid outlet pipe 42 according to the obtained leakage signal. If it is in a leakage state, a corresponding working signal is directly sent to the start-stop device to control the start-stop device to stop the delivery of the coolant. If it is not in a leakage state, the temperature value corresponding to the leakage signal is further obtained. When the temperature value is lower than the standard temperature of the air outlet of the server cabinet, the control component sends a corresponding working signal to the start-stop device to reduce the delivery flow of the coolant. When the temperature value is lower than the standard temperature of the air outlet of the server cabinet, the delivery flow of the coolant is increased.

[0067] Since the base plate 1 in the liquid cooling adjustment component is installed at the air outlet of the cabinet, when the hot air is continuously dissipated from the air outlet of the cabinet, the hot air continues to pass through the liquid inlet pipe 41 and the liquid outlet pipe 42 in the liquid cooling component. When the continuously circulating coolant flows through the liquid inlet pipe 41 and the liquid outlet pipe 42, the coolant passes through the liquid inlet pipe 41 and the liquid outlet pipe 42 to continuously exchange heat with the hot air to absorb the heat in the hot air, and circulates back to the cold source from the liquid outlet pipe 42 to achieve the effect of assisting the heat dissipation of the server cabinet.

[0068] It should be further explained that, in actual use, the staff can increase the number of liquid inlet pipes 41 and liquid outlet pipes 42 according to the actual auxiliary cooling needs, thereby increasing the number of connecting parts, or increasing the diameter of the connecting parts of the liquid inlet pipes 41 and the liquid outlet pipes 42, so as to enhance the overall auxiliary cooling effect by increasing the heat transfer area.

[0069] In this embodiment, by extending the connecting portion of the liquid inlet pipe 41 and the liquid outlet pipe 42 in the liquid cooling component, and using the cooling liquid circulating in the liquid inlet pipe 41 and the liquid outlet pipe 42 to perform heat exchange with the hot air blown to the connecting portion of the liquid inlet pipe 41 and the liquid outlet pipe 42 at the air outlet of the server cabinet, the heat at the air outlet of the server cabinet can be taken away, and the effect of assisting the heat dissipation of the server is achieved with a simple liquid cooling pipe layout and a small occupied space;

[0070] Compared with the prior art, the present invention has the following advantages:

[0071] 1. The liquid cooling pipeline layout designed by the present invention is simple. By arranging the liquid cooling component on the fixed partition 2 and extending the connecting part of the liquid inlet pipeline 41 and the liquid outlet pipeline 42 in the liquid cooling component to the air outlet of the server cabinet, the effect of assisting the heat dissipation of the server is achieved with a simple liquid cooling pipeline layout and a small occupied space;

[0072] 2. The liquid cooling component designed in the present invention has a relatively low cost and can be directly disassembled from the fixed partition 2 as a whole, which is convenient for workers to install, perform routine maintenance and replace the liquid cooling component, thereby improving the installation and maintenance work efficiency of workers and reducing installation and maintenance costs;

[0073] 3. The regulating component 44 designed in the present invention can, on the one hand, adaptively adjust the coolant flow rate of the connecting part of the liquid inlet pipe 41 and the liquid outlet pipe 42 according to the temperature of the air outlet of the server cabinet, so as to adaptively adjust the cooling effect to avoid the situation where the temperature at the air outlet is too low or too high, which may affect the server. On the other hand, it can control the start and stop of the start-stop device according to the leakage of the liquid inlet pipe 41 and the liquid outlet pipe 42 in the liquid cooling component to prevent the cooling source from continuously passing the cooling liquid when leakage occurs, resulting in the accumulation of cooling liquid in the server cabinet.

[0074] In one embodiment, the liquid outlet pipe 42 is connected to a storage branch pipe 421 , a suction pump 422 is installed on the storage branch pipe 421 , the storage branch pipe 421 is connected to a reservoir, and the suction pump 422 is electrically connected to the control component.

[0075] It should be noted that the suction pump 422 can receive a working signal from the control component and work according to the corresponding working signal;

[0076] Specifically, when the leakage signal obtained by the control component determines that the liquid inlet pipe 41 and the liquid outlet pipe 42 are in a leakage state, and sends a working signal to the start-stop device to control the start-stop device to stop the delivery of the coolant, the control component synchronously sends a working signal to the suction pump 422 to control the suction pump 422 to work briefly. The specific working time is 1-2 seconds. The suction pump 422 can quickly absorb the remaining coolant in the liquid outlet pipe 42 into the storage branch pipe 421 during the working time, so as to avoid the coolant flowing out of the liquid outlet pipe 42 during the subsequent maintenance or replacement of liquid cooling components by the staff.

[0077] In this embodiment, through the storage branch pipe 421 and the suction pump 422 electrically connected to the control component, the remaining coolant in the liquid outlet pipe 42 can be quickly sucked into the storage branch pipe 421 when the liquid cooling component leaks, thereby reducing the situation where the coolant flows out of the liquid cooling component when the subsequent staff maintains or replaces the liquid cooling component.

[0078] In one embodiment, a delivery branch pipe 43 is connected between the liquid inlet pipe 41 and the liquid outlet pipe 42 , and an isolation valve 431 is installed at one end of the delivery branch pipe 43 connected to the liquid inlet pipe 41 , and the isolation valve 431 is electrically connected to the control component.

[0079] It should be noted that the isolation valve 431 can receive a working signal from the control component and work according to the corresponding working signal;

[0080] Specifically, when the leakage signal obtained by the control component determines that the liquid inlet pipeline 41 and the liquid outlet pipeline 42 are in a leakage state, and sends a working signal to the start-stop device to control the start-stop device to stop the delivery of the coolant, the synchronous control component sends a working signal to the isolation valve 431 to control the isolation valve to close, thereby isolating the liquid inlet pipeline 41 and the delivery branch pipe 43, thereby achieving the effect of stopping the delivery of coolant to the delivery branch pipe 43 where the leakage occurs.

[0081] In this embodiment, through the delivery branch pipe 43 and the isolation valve 431 electrically connected to the control component, the coolant in the liquid inlet pipe 41 can be isolated from the delivery branch pipe 43 when leakage occurs in the liquid cooling component, thereby achieving the effect of stopping the delivery of coolant to the delivery branch pipe 43 where the leakage occurs.

[0082] In one embodiment, the other end of the delivery branch pipe 43 is connected to the liquid outlet pipe 42 through a middle piece 432 .

[0083] In one embodiment, a plurality of liquid cooling grooves 21 are formed on the fixed partition plate 2 , and the delivery branch pipe 43 is connected to the liquid inlet pipe 41 and the liquid outlet pipe 42 through the plurality of liquid cooling grooves 21 .

[0084] It should be noted that the intermediate piece 432 can be a detachable connector 31 of the same type as a hose clamp, so that when the staff needs to perform routine maintenance or replacement of the liquid cooling component, the delivery branch pipe 43 can be directly separated from the liquid outlet pipe 42 by disassembling the detachable connector 31 at the liquid delivery pipe;

[0085] It should be additionally explained that the two ends of the delivery branch pipe 43 pass through two liquid cooling grooves 21 respectively to be connected with the liquid inlet pipe 41 and the liquid outlet pipe 42 respectively, which can play a role of limiting support for the delivery branch pipe 43 to prevent the delivery branch pipe 43 from sagging under the action of gravity, thereby affecting the auxiliary cooling effect.

[0086] In one embodiment, a sliding groove is provided inside the fixed partition plate 2 , and the sliding groove is located below the liquid cooling groove 21 . A blocking member 22 is slidably connected inside the sliding groove.

[0087] It should be noted that the blocking member 22 is adapted to the liquid cooling groove 21 , and the blocking member 22 is used to limit and fasten the delivery branch pipe 43 in the liquid cooling groove 21 .

[0088] In this embodiment, through the cooperation of the sliding groove and the blocking member 22, on the one hand, the blocking member 22 can slide in the sliding groove to limit and tighten the delivery branch pipe 43 in the liquid cooling groove 21; on the other hand, it can prevent the hot air emitted from the air outlet of the server cabinet from blowing from the liquid cooling groove 21 to the liquid cooling component and affecting the working state of the liquid cooling component.

[0089] In one embodiment, at least two delivery branches 43 are provided, and a temperature sensor is provided at the connection end between the delivery branch 43 and the liquid outlet pipe 42. A flow distributor 433 is installed on the two delivery branches 43, and the temperature sensor is connected to the flow distributor 433, and the flow distributor 433 is electrically connected to the control component.

[0090] It should be noted that a temperature sensor is installed at the connection end between the delivery branch pipe 43 and the liquid outlet pipe 42. The temperature sensor can obtain the temperature information of the connection end between the delivery branch pipe 43 and the liquid outlet pipe 42, and feed it back to the flow distributor 433. The flow distributor 433 transmits the temperature information to the control component, and then the control component controls the coolant flow rate delivered by each delivery branch pipe 43 in the flow distributor 433 according to the temperature information, that is, reduces the coolant flow rate of the delivery branch pipe 43 whose temperature is lower than the standard temperature, and increases the coolant flow rate of the delivery branch pipe 43 whose temperature is higher than the standard temperature, so as to improve the cooling efficiency of the overall cooling component.

[0091] In this embodiment, through at least two delivery branches 43, a temperature sensor and a flow distributor 433 electrically connected to the control component, the coolant flow in each delivery branch 43 can be controlled according to the temperature of each delivery branch 43 to improve the cooling efficiency of the overall cooling component.

[0092] In one embodiment, the movable door 3 is movably connected to the base plate 1 via a connecting member 31 .

[0093] In one embodiment, an inclined bracket is also installed inside the liquid cooling chamber 4, and the liquid cooling adjustment assembly is installed on the inclined bracket. One end of the inclined bracket is connected to the movable door 3, and the other end is located at the bottom of the liquid cooling chamber 4. The connecting member 31 is located at the bottom of the movable door 3.

[0094] In this embodiment, through the cooperation of the connecting piece 31 and the tilt bracket, the base plate 1 can be taken out as a whole by opening the movable door 3, and then the liquid cooling adjustment components inside the server cabinet or the base plate 1 can be maintained or replaced daily, thereby improving the work efficiency of the staff in installation or daily maintenance.

[0095] In one embodiment, a horizontal guide rail 32 is further installed at the bottom of the liquid cooling chamber 4 , the liquid cooling adjustment assembly is movably connected to the horizontal guide rail 32 , and the connecting member 31 is located on the side of the movable door 3 .

[0096] In this embodiment, through the cooperation of the connecting piece 31 and the horizontal guide rail 32, the movable door 3 can be opened and the substrate 1 can be horizontally taken out of the liquid cooling chamber 4 as a whole, so as to perform daily maintenance or replacement of the liquid cooling adjustment components inside the server cabinet or the substrate 1, thereby improving the work efficiency of the staff in installation or daily maintenance.

[0097] The following is a detailed description of how the control components work in the complete workflow:

[0098] Preferably, a plurality of delivery branches 43 are provided between the liquid inlet pipe 41 and the liquid outlet pipe 42 in the liquid cooling component, temperature sensors are provided on the connection ends of the plurality of delivery branches 43 and the liquid outlet pipe 42, and a liquid leakage detection sensor is provided on the delivery branch pipe 43. The temperature sensor and the liquid leakage detection sensor are both indirectly electrically connected to the processor in the control component through the signal transceiver in the control component to receive the working signal from the processor or transmit the corresponding signal to the processor; the components electrically connected to the control component include the start-stop device, the suction pump 422, the isolation valve 431 and the flow distributor 433;

[0099] In actual use, when the liquid cooling component is working, the control component continuously obtains the temperature signal from the temperature sensing module, the leakage signal from each leakage detection sensor and the temperature information from the temperature sensor, among which the leakage signal is processed first to determine whether it is in a leakage state:

[0100] When it is determined that the liquid is leaking, it will be further determined which leakage detection sensor the leaking delivery branch pipe 43 belongs to, so as to distinguish the normal delivery branch pipe 43 from the leaking delivery branch pipe 43, and control the isolation valve 431 at the leaking delivery branch pipe 43 to start, so as to isolate the liquid inlet pipe 41 from the leaking delivery branch pipe 43:

[0101] If there is a normal delivery branch pipe 43, the control component will give priority to processing the temperature signal, so as to control the power of the start-stop device according to the temperature signal to control the rate at which the coolant enters the liquid inlet pipe 41, and then control the flow distributor 433 to evenly distribute the coolant to the normal delivery branch pipe 43 to start the auxiliary cooling work. When the temperature information at each delivery branch pipe 43 is different, the processor in the control component compares the temperature information at each delivery branch pipe 43 with the standard temperature, and then controls the flow distributor 433 to adaptively distribute the coolant in the normal delivery branch pipe 43 according to the temperature difference;

[0102] If there is no normal delivery branch pipe 43 and all detection sensors are in a leaking state, the control component controls the start-stop device not to work and controls the suction pump 422 to start working.

[0103] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
