Description

Technical Field

[0001] The present application relates to the technical field of server heat exchange, and in particular to a cooling circulation device. In addition, the present application also relates to an immersion liquid cooling cabinet including the above cooling circulation device and a control method applied to the above cooling circulation device. Background Art

[0002] With the continuous improvement of the power density of computing devices, the limitations of traditional air-cooled heat dissipation methods have gradually emerged, and immersion liquid cooling technology is an innovative heat dissipation solution.

[0003] In existing high-density immersion liquid cooling cabinets, the heat circulation system of the liquid cooling cabinet mainly adopts an independent cooling circulation system or a centralized cooling circulation system.

[0004] The initial layout cost of an independent cooling circulation system is relatively high. Each cabinet requires an independent pump and heat exchanger, increasing equipment and operation and maintenance costs; in addition, the independent cooling circulation system occupies a large space.

[0005] The centralized cooling circulation system has a risk of single-point failure. A single-node failure may affect the operation of other nodes in the centralized system; in addition, the centralized cooling circulation system is complex to operate and maintain. The maintenance and upgrade of the centralized system may affect the operation of the entire computer room; and the flexibility of the centralized cooling circulation system is relatively low, and it is difficult to make independent adjustments for a single liquid cooling cabinet. Summary of the Invention

[0006] The present application provides a cooling circulation device. In the normal refrigeration state, the control system controls the liquid control component to connect the mechanism to be cooled with the corresponding centralized cooling system; in the fault or maintenance state, the control system controls the liquid control component to connect the mechanism to be cooled with the corresponding independent cooling system; so as to at least solve the problems in the related art that only setting an independent cooling circulation system has high cost and large space occupation, and only setting a centralized cooling circulation system has risks of single-point failure, complex operation and maintenance, and low flexibility.

[0007] The present application provides a cooling circulation device, including a liquid control component, a control system, an independent cooling system, and a centralized cooling system;

[0008] The number of the liquid control components is at least two, and at least two of the liquid control components are used to be arranged in one-to-one correspondence with the mechanism to be cooled;

[0009] In the normal refrigeration state, the control system controls the liquid control component to act, so that the mechanism to be cooled is communicated with the corresponding centralized cooling system, and the corresponding centralized cooling system cools and dissipates heat from the mechanism to be cooled; and the same centralized cooling system is simultaneously communicated with at least two mechanisms to be cooled;

[0010] In the event of a fault or maintenance, the control system controls the hydraulic control component to act, so that the mechanism to be cooled is communicated with the corresponding independent cooling system, so as to repair or maintain the mechanism to be cooled that needs to be repaired or maintained; and the same independent cooling system is simultaneously communicated with one mechanism to be cooled.

[0011] The present application further provides an immersion liquid-cooled cabinet, including the cooling circulation device described in any one of the above and at least two mechanisms to be cooled. The mechanism to be cooled is a liquid-cooled cabinet, and a plurality of heating devices are arranged in the liquid-cooled cabinet.

[0012] The present application further provides a control method, which is applied to the cooling circulation device described in any one of the above. The control method includes:

[0013] Judge whether the mechanism to be cooled is in a fault or maintenance state. If so, control the hydraulic control component to act, so that the mechanism to be cooled is communicated with the corresponding independent cooling system, so as to repair or maintain the mechanism to be cooled that needs to be repaired or maintained; if not, proceed to the next step;

[0014] Control the hydraulic control component to act, so that the mechanism to be cooled is communicated with the corresponding centralized cooling system, and cool and dissipate heat from the mechanism to be cooled through the corresponding centralized cooling system.

[0015] Through the present application, since an independent cooling system and a centralized cooling system are both provided, and during actual use, when the liquid-cooled mechanism is in a normal working state, the cooling circulation device can start the normal refrigeration state, and the control system controls the hydraulic control component to act, so that the mechanism to be cooled is communicated with the corresponding centralized cooling system, and the mechanism to be cooled is cooled and dissipated heat through the corresponding centralized cooling system; when the mechanism to be cooled fails or needs maintenance, the cooling circulation device can start the fault or maintenance state; the control system controls the hydraulic control component to act, so that the mechanism to be cooled is communicated with the corresponding independent cooling system, so as to repair or maintain the mechanism to be cooled that needs to be repaired or maintained.

[0016] Compared with only setting a centralized cooling system, the setting of the independent cooling system in the present application can effectively solve the problem of single-point failure risk. For the situation where a single mechanism to be cooled fails, it is possible to specifically control the failed mechanism to be cooled to be communicated with the corresponding independent cooling system, without affecting the normal operation of other mechanisms to be cooled; when it is necessary to maintain the mechanism to be cooled, it is possible to specifically control the mechanism to be cooled that needs to be maintained to be communicated with the corresponding independent cooling system. During the maintenance process of the mechanism to be cooled that needs to be maintained, the normal operation of other mechanisms to be cooled is not affected; and during the maintenance operation process, multiple mechanisms to be cooled can be maintained sequentially to avoid the situation where the entire mechanism to be cooled is shut down for maintenance and affects the normal work.

[0017] Compared with only setting up an independent cooling system, in the present application, when the mechanism to be cooled is in the normal working state, the centralized cooling system is used to cool and lower the temperature of the mechanism to be cooled, which can effectively reduce the number of independent cooling systems set up and reduce costs.

[0018] Therefore, it can solve the technical problems that only setting up an independent cooling cycle system has high costs and occupies a large space, and only setting up a centralized cooling cycle system has risks of single-point failures, complex operation and maintenance, and low flexibility, and achieve the technical effects of reducing costs and avoiding the impact of single-point failures on the normal operation of other mechanisms to be cooled.

[0043] 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 belong to the protection scope of the present application.

[0044] 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. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, that the difference between the two equal ones is less than or equal to 5% of either one of them. 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 circumstances.

[0045] 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.

[0046] Embodiments of the present application provide a cooling cycle device, including a liquid control component 1, a control system 2, and a cooling system 3. The cooling system 3 includes an independent cooling system 31 and a centralized cooling system 32. The number of liquid control components 1 is at least two, and at least two liquid control components 1 are used to be arranged in one-to-one correspondence with the to-be-cooled mechanism 4 to be cooled. In the normal refrigeration state, the control system 2 controls the liquid control component 1 to act, so that the to-be-cooled mechanism 4 is communicated with the corresponding centralized cooling system 32, and the to-be-cooled mechanism 4 is cooled and dissipated heat through the corresponding centralized cooling system 32. And at the same time, the same centralized cooling system 32 is communicated with at least two to-be-cooled mechanisms 4. In the fault or maintenance state, the control system 2 controls the liquid control component 1 to act, so that the to-be-cooled mechanism 4 is communicated with the corresponding independent cooling system 31, so as to repair or maintain the to-be-cooled mechanism 4 that needs to be repaired or maintained. And at the same time, the same independent cooling system 31 is communicated with one to-be-cooled mechanism 4.

[0047] It should be noted that in the actual use process of the centralized cooling system 32 in this specific embodiment, the same centralized cooling system 32 can be communicated with multiple to-be-cooled mechanisms 4 at the same time, and cool and cool down multiple to-be-cooled mechanisms 4 at the same time. In the actual use process of the independent cooling system 31, at the same moment, the same independent cooling system 31 can only be connected to one to-be-cooled mechanism 4. After the fault or maintenance state of this to-be-cooled mechanism 4 ends, this to-be-cooled mechanism 4 can be switched to be communicated with the centralized cooling system 32. This independent cooling system 31 is switched to be communicated with other to-be-cooled mechanisms 4 in the fault or maintenance state.

[0048] It should be noted that the to-be-cooled mechanism 4 in this specific embodiment can be a liquid-cooled cabinet 41 or a liquid immersion cooling cabinet, or other heating devices that require liquid-cooled heat dissipation, which is specifically determined according to the actual situation and will not be elaborated here.

[0049] In this specific embodiment, an independent cooling system 31 and a centralized cooling system 32 are provided at the same time. And in the actual use process, when the liquid-cooled mechanism is in the normal working state, the cooling cycle device can start the normal refrigeration state, and the control system 2 controls the liquid control component 1 to act, so that the to-be-cooled mechanism 4 is communicated with the corresponding centralized cooling system 32, and the to-be-cooled mechanism 4 is cooled and dissipated heat through the corresponding centralized cooling system 32. When the to-be-cooled mechanism 4 fails or needs maintenance, the cooling cycle device can start the fault or maintenance state. The control system 2 controls the liquid control component 1 to act, so that the to-be-cooled mechanism 4 is communicated with the corresponding independent cooling system 31, so as to repair or maintain the to-be-cooled mechanism 4 that needs to be repaired or maintained.

[0050] Compared with only setting the centralized cooling system 32, the setting of the independent cooling system 31 in this application can effectively solve the problem of single-point failure risk. In the case of a failure of a single cooling mechanism 4 to be cooled, it is possible to specifically control the connection between the failed cooling mechanism 4 to be cooled and the corresponding independent cooling system 31, without affecting the normal operation of other cooling mechanisms 4 to be cooled; when maintenance needs to be carried out on the cooling mechanism 4 to be cooled, it is possible to control the connection between the cooling mechanism 4 to be maintained and the corresponding independent cooling system 31 according to the cooling mechanism 4 to be maintained. During the maintenance process of the cooling mechanism 4 to be maintained, it does not affect the normal operation of other cooling mechanisms 4 to be cooled; and during the maintenance operation process, multiple cooling mechanisms 4 to be cooled can be maintained in sequence to avoid the situation where the entire cooling mechanism 4 to be cooled is shut down for maintenance and affects normal work.

[0051] Compared with only setting the independent cooling system 31, in the normal working state of the cooling mechanism 4 to be cooled in this application, the centralized cooling system 32 is used to cool and lower the temperature of the cooling mechanism 4 to be cooled, which can effectively reduce the number of independent cooling systems 31 set and reduce costs.

[0052] Therefore, it is possible to solve the technical problems that only setting an independent cooling cycle system has high costs and occupies a large space, and only setting a centralized cooling cycle system has single-point failure risks, complex operation and maintenance, and low flexibility, and achieve the technical effects of reducing costs and avoiding single-point failures from affecting the normal operation of other cooling mechanisms 4 to be cooled.

[0053] In a specific embodiment, the liquid control component 1 includes an inlet pipeline 11 and an outlet pipeline 12; the inlet pipeline 11 is used to enable the liquid cooling working medium in the cooling mechanism 4 to enter the independent cooling system 31 or the centralized cooling system 32 through the inlet pipeline 11; the outlet pipeline 12 is used to enable the cooling working medium that has completed heat exchange in the independent cooling system 31 or the centralized cooling system 32 to flow back to the cooling mechanism 4 through the outlet pipeline 12.

[0054] It should be noted that the inlet pipeline 11 in this specific embodiment does not refer to a single pipeline, but a collection of a series of pipelines to realize the connection of different centralized cooling systems 32 or different independent cooling systems 31. The outlet pipeline 12 in this specific embodiment does not refer to a single pipeline, but a collection of a series of pipelines to realize the connection of different centralized cooling systems 32 or different independent cooling systems 31.

[0055] During the actual use process, in combination with the Figure 2, under the control of the liquid control component 1, in the normal refrigeration state, the liquid cooling working medium in the mechanism to be cooled 4 enters the centralized cooling system 32 through the liquid inlet pipeline 11. In the centralized cooling system 32, the liquid cooling working medium flowing out of the mechanism to be cooled 4 completes heat exchange, and the temperature of the liquid cooling working medium decreases. After completing heat exchange, the liquid cooling working medium returns to the mechanism to be cooled 4 through the liquid outlet of the centralized cooling system 32 and the liquid outlet pipeline 12, and continues to cool down the mechanism to be cooled 4. In the case of a fault or maintenance state, the liquid control component 1 controls the mechanism to be cooled 4 to communicate with the corresponding independent cooling system 31; the liquid cooling working medium in the mechanism to be cooled 4 enters the corresponding independent cooling system 31 through the liquid inlet pipeline 11. In the independent cooling system 31, the liquid cooling working medium flowing out of the mechanism to be cooled 4 completes heat exchange, and the temperature of the liquid cooling working medium decreases. After completing heat exchange, the liquid cooling working medium returns to the mechanism to be cooled 4 through the liquid outlet of the independent cooling system 31 and the liquid outlet pipeline 12, and continues to cool down the mechanism to be cooled 4.

[0056] In this specific embodiment, by setting the liquid inlet pipeline 11 and the liquid outlet pipeline 12, the connection between the mechanism to be cooled 4 and the centralized cooling system 32 or the independent cooling system 31 is realized. By controlling the on-off of the liquid inlet pipeline 11 and the liquid outlet pipeline 12, the circulation control of the liquid cooling working medium in the mechanism to be cooled 4 can be realized. The control process is convenient and easy to operate.

[0057] In a specific embodiment, as Figure 4 shown, the liquid inlet pipeline 11 can include a first pipeline 111 for connecting to the liquid outlet end of the mechanism to be cooled 4, a second pipeline 112 for connecting to the liquid inlet end of the independent cooling system 31, and a third pipeline 113 for connecting to the liquid inlet end of the centralized cooling system 32; a first control valve 114 for controlling its on-off is provided on the first pipeline 111, a second control valve 115 for controlling its on-off is provided on the second pipeline 112, and a third control valve 116 for controlling its on-off is provided on the third pipeline 113; the second pipeline 112 includes at least two second pipeline branches 1121, and at least two second pipeline branches 1121 are respectively connected to different independent cooling systems 31; the third pipeline 113 includes at least two third pipeline branches 1131, and at least two third pipeline branches 1131 are respectively connected to different said centralized cooling systems 32.

[0058] As Figure 4As shown, the liquid outlet pipeline 12 includes a fourth pipeline 121 for connecting to the liquid inlet end of the mechanism to be cooled 4, a fifth pipeline 122 for connecting to the liquid outlet end of the independent cooling system 31, and a sixth pipeline 123 for connecting to the liquid outlet end of the centralized cooling system 32; a fourth control valve 124 for controlling its on-off is provided on the fourth pipeline 121, a fifth control valve 125 for controlling its on-off is provided on the fifth pipeline 122, and a sixth control valve 126 for controlling its on-off is provided on the sixth pipeline 123; the fifth pipeline 122 includes at least two fifth pipeline branches 1221, and at least two fifth pipeline branches 1221 are respectively connected to different independent cooling systems 31; the sixth pipeline 123 includes at least two sixth pipeline branches 1231, and at least two sixth pipeline branches 1231 are respectively connected to different centralized cooling systems 32; the first control valve 114, the second control valve 115, the third control valve 116, the fourth control valve 124, the fifth control valve 125, and the sixth control valve 126 are all connected to the control system 2.

[0059] In this specific embodiment, the first control valve 114, the second control valve 115, the third control valve 116, the fourth control valve 124, the fifth control valve 125, and the sixth control valve 126 can all be set as electric control valves, or can be set as other types of valve bodies that meet the requirements, which are specifically determined according to the actual situation and will not be elaborated here.

[0060] During the actual use process, when the liquid cooling mechanism is in a normal working state, first, obtain the heat generation power of the mechanism to be cooled 4, control the liquid control component 1 to act according to the heat generation power of the mechanism to be cooled 4, and control the first control valve 114, the corresponding third control valve 116, the fourth control valve 124, and the corresponding sixth control valve 126 to open to connect to the corresponding centralized cooling system 32; as Figure 3 、 Figure 4 shown, the liquid cooling working medium in the mechanism to be cooled 4 enters the corresponding centralized cooling system 32 through the liquid outlet of the mechanism to be cooled 4, the first pipeline 111, the third pipeline 113, and the liquid inlet of the centralized cooling system 32. In the centralized cooling system 32, the liquid cooling working medium flowing out of the mechanism to be cooled 4 completes the heat exchange, the temperature of the liquid cooling working medium decreases, and the liquid cooling working medium after completing the heat exchange returns to the mechanism to be cooled 4 through the liquid outlet of the centralized cooling system 32, the sixth pipeline 123, the fourth pipeline 121, and the liquid inlet of the mechanism to be cooled 4, and continues to cool down the mechanism to be cooled 4.

[0061] When the liquid cooling mechanism is in a faulty or maintenance state, it is necessary to control the first control valve 114, the corresponding second control valve 115, the fourth control valve 124, and the corresponding fifth control valve 125 to open through the liquid control component 1 to connect to the corresponding independent cooling system 31; as Figure 3 、 Figure 4As shown, the liquid cooling working medium in the to-be-cooled mechanism 4 enters the corresponding independent cooling system 31 through the liquid outlet of the to-be-cooled mechanism 4, the first pipeline 111, the second pipeline 112, and the liquid inlet of the independent cooling system 31. Inside the independent cooling system 31, the liquid cooling working medium flowing out of the to-be-cooled mechanism 4 completes heat exchange, and the temperature of the liquid cooling working medium decreases. After completing heat exchange, the liquid cooling working medium returns to the to-be-cooled mechanism 4 through the liquid outlet of the independent cooling system 31, the fifth pipeline 122, the fourth pipeline 121, and the liquid inlet of the to-be-cooled mechanism 4, and continues to cool down the to-be-cooled mechanism 4.

[0062] In this specific embodiment, by setting at least two second pipeline branches 1121, at least two third pipeline branches 1131, at least two fifth pipeline branches 1221, and at least two sixth pipeline branches 1231, during actual use, different centralized cooling systems 32 can be matched according to the different heating powers of the to-be-cooled mechanism 4 to achieve targeted cooling and effectively save energy. Moreover, the same to-be-cooled mechanism 4 can be connected to different independent cooling systems 31. During actual use, when some of the independent cooling systems 31 are in working state, other independent cooling systems 31 can be switched and connected to ensure that the to-be-cooled mechanism 4 in a faulty or maintenance state can be cooled in time.

[0063] It should be noted that as Figure 3 , Figure 4 shown, the second control valve 115 can be set in the second pipeline branch 1121, the third control valve 116 can be set in the third pipeline branch 1131, the fifth control valve 125 can be set in the fifth pipeline branch 1221, and the sixth control valve 126 can be set in the sixth pipeline branch 1231 to realize the on-off control of the corresponding branches.

[0064] On the basis of the above embodiment, check valves can be set in the first pipeline 111, the second pipeline 112, the third pipeline 113, the fourth pipeline 121, the fifth pipeline 122, and the sixth pipeline 123; the check valves are connected to the control system 2. As Figure 3 , Figure 4 shown, the first pipeline 111 is provided with a first check valve 1111, the second pipeline 112 is provided with a second check valve 1122, the third pipeline 113 is provided with a third check valve 1132, the fourth pipeline 121 is provided with a fourth check valve 1211, the fifth pipeline 122 is provided with a fifth check valve 1222, and the sixth pipeline 123 is provided with a sixth check valve 1232.

[0065] The setting of the check valve can effectively prevent the reverse flow of the liquid cooling working medium, effectively limit the flow direction of the liquid cooling working medium, is beneficial to improving the heat exchange effect of the liquid cooling working medium, and further improves the cooling effect of the cooling circulation device.

[0066] Based on the above embodiments, the liquid control component 1 further includes a chamber, and a detection mechanism for detecting the liquid cooling working medium is arranged in the chamber. The detection mechanism includes a first detection mechanism 13 for detecting the liquid cooling working medium in the liquid inlet pipeline 11 and a second detection mechanism 14 for detecting the liquid cooling working medium in the liquid outlet pipeline 12; the detection mechanism is connected to the control system 2.

[0067] As Figure 3 , Figure 4 shown, the chamber includes a first installation chamber 131 and a second installation chamber 141. The first installation chamber 131 is communicated with the liquid inlet pipeline 11, and the first detection mechanism 13 is arranged in the first installation chamber 131. The second installation chamber 141 is communicated with the liquid outlet pipeline 12, and the second detection mechanism 14 is arranged in the second installation chamber 141.

[0068] It should be noted that the first detection mechanism 13 and the second detection mechanism 14 in this specific embodiment may both include at least one of a temperature sensor, a flow meter, a pressure sensor, a conductivity sensor, a pH value sensor, a particulate matter detector, a liquid level sensor, a chemical composition analyzer, and a microorganism detection module, or may also include other detection mechanisms, which are specifically determined according to the actual situation.

[0069] During actual use, when the liquid cooling working medium flows through the liquid inlet pipeline 11, the liquid cooling working medium can be detected by the first detection mechanism 13. When the liquid cooling working medium flows through the liquid outlet pipeline 12, the liquid cooling working medium can be detected by the second detection mechanism 14.

[0070] Specifically, as Figure 1 shown, the control system 2 includes an IC (Integrated Circuit, integrated circuit 22), a BMC (Baseboard Management Controller, baseboard management controller 21), a serial port 23, a display 24, and a network port 25. Among them, the serial port 23 is connected to the BMC through a UART (Universal Asynchronous Receiver / Transmitter, asynchronous transceiver), the display 24 is connected to the BMC through a VGA (Video Graphics Array, analog signal transmission standard interface), and the network port 25 is connected to the BMC through a network cable. During actual use, the detection results of the first detection mechanism 13 and the second detection mechanism 14 can be transmitted to the control system 2. The IC in the control system 2 receives the detection results of the first detection mechanism 13 and the second detection mechanism 14 and transmits the detection results to the BMC. The BMC processes the detection results and displays them through the display 24.

[0071] In this specific embodiment, the BMC management board is externally connected to a serial port 23, a display 24, and a network port 25, facilitating the staff to monitor the entire intelligent cooling circulation system in various ways. The control system 2IC communicates with the liquid control component 1, the cooling system 3, and the device to be cooled 4, receives signals, and issues control instructions.

[0072] In this specific embodiment, by setting the first detection mechanism 13 and the second detection mechanism 14, the liquid cooling working medium flowing into or out of the independent cooling system 31 or the centralized cooling system 32 can be detected, facilitating the timely acquisition of the quality information of the liquid cooling working medium and avoiding the influence of the quality problem of the liquid cooling working medium on the cooling effect.

[0073] In a specific embodiment, a position detection component can be set for any device to be cooled 4. The position detection component is used to obtain the position or number information of the corresponding device to be cooled 4. The control system 2 further includes a warning device; the liquid control component 1 further includes a filtering device. The filtering device is arranged on the liquid outlet pipeline 12 or the liquid inlet pipeline 11, or the filtering device is arranged in the second installation chamber communicated with the liquid outlet pipeline 12, or the filtering device is arranged in the first installation chamber 131 communicated with the liquid inlet pipeline 11.

[0074] During the actual use process, when the detection mechanism detects that the quality of the liquid cooling working medium does not meet the requirements, the control system 2 controls the warning device to send out corresponding warning information; and controls the filtering device to work for a preset time. If the quality of the liquid cooling working medium returns to meet the requirements within the preset time, the warning information of the warning device is cancelled; when the quality of the liquid cooling working medium still does not meet the requirements within the preset time, it is necessary to obtain the position information of the corresponding device to be cooled 4 through the position detection component, and perform maintenance or replacement of the cooling working medium on the device to be cooled 4 at the corresponding position.

[0075] In this specific embodiment, by setting the position detection component, the warning device, and the filtering device, the liquid cooling working medium that does not meet the requirements can be filtered, and warning information can be sent out in time when the liquid cooling working medium does not meet the requirements, facilitating the staff to timely know the quality situation of the liquid cooling working medium. In the case where the liquid cooling working medium still does not meet the requirements after the preset filtering time, the position of the device to be cooled 4 to be repaired can be timely obtained through the position detection component, facilitating the maintenance personnel to quickly determine the position of the device to be cooled 4 to be repaired, which is beneficial to shortening the maintenance time and improving the maintenance efficiency.

[0076] In a specific embodiment, it further includes a power detection mechanism for detecting the heating power of the mechanism to be cooled 4. The power detection mechanism is connected to the control system 2 and transmits the obtained power information to the control system 2. The centralized cooling system 32 includes a high-power consumption centralized cooling system 321, a medium-power consumption centralized cooling system 322, and a low-power consumption centralized cooling system 323. When the power detection mechanism detects that the heating power of the mechanism to be cooled 4 is within the high-power consumption range, the hydraulic control component 1 is controlled to act so that the mechanism to be cooled 4 is communicated with the high-power consumption centralized cooling system 321. When the power detection mechanism detects that the heating power of the mechanism to be cooled 4 is within the medium-power consumption range, the hydraulic control component 1 is controlled to act so that the mechanism to be cooled 4 is communicated with the medium-power consumption centralized cooling system 322. When the power detection mechanism detects that the heating power of the mechanism to be cooled 4 is within the low-power consumption range, the hydraulic control component 1 is controlled to act so that the mechanism to be cooled 4 is communicated with the low-power consumption centralized cooling system 323.

[0077] The refrigeration efficiencies of the high-power consumption centralized cooling system 321, the medium-power consumption centralized cooling system 322, and the low-power consumption centralized cooling system 323 decrease in sequence from high to low. The minimum heating power in the high-power consumption range is higher than or equal to the maximum heating power in the medium-power consumption range. The minimum heating power in the medium-power consumption range is higher than or equal to the maximum heating power in the low-power consumption range.

[0078] It should be noted that during actual use, when the power detection mechanism detects that the heating power of the mechanism to be cooled 4 is within the high-power consumption range, the refrigerant efficiency of the high-power consumption centralized cooling system 321 needs to be adjusted so that the refrigeration efficiency of the high-power consumption centralized cooling system 321 matches the heating power of the mechanism to be cooled 4, or by adjusting parameters such as the flow rate and temperature of the liquid cooling working medium, the refrigeration efficiency of the high-power consumption centralized cooling system 321 is made to match the heating power of the mechanism to be cooled 4. When the power detection mechanism detects that the heating power of the mechanism to be cooled 4 is within the medium-power consumption range, the refrigerant efficiency of the medium-power consumption centralized cooling system 322 needs to be adjusted so that the refrigeration efficiency of the medium-power consumption centralized cooling system 322 matches the heating power of the mechanism to be cooled 4, or by adjusting parameters such as the flow rate and temperature of the liquid cooling working medium, the refrigeration efficiency of the medium-power consumption centralized cooling system 322 is made to match the heating power of the mechanism to be cooled 4. When the power detection mechanism detects that the heating power of the mechanism to be cooled 4 is within the low-power consumption range, the refrigerant efficiency of the low-power consumption centralized cooling system 323 needs to be adjusted so that the refrigeration efficiency of the low-power consumption centralized cooling system 323 matches the heating power of the mechanism to be cooled 4, or by adjusting parameters such as the flow rate and temperature of the liquid cooling working medium, the refrigeration efficiency of the low-power consumption centralized cooling system 323 is made to match the heating power of the mechanism to be cooled 4.

[0079] In this specific embodiment, by setting up a power detection mechanism and configuring the centralized cooling system 32 to include a high-power consumption centralized cooling system 321, a medium-power consumption centralized cooling system 322, and a low-power consumption centralized cooling system 323, during actual use, different centralized cooling systems 32 can be matched according to the different heating powers of the mechanism 4 to be cooled, achieving the effect of energy conservation. Additionally, matching different centralized cooling systems 32 for different heating powers can also effectively improve the cooling effect of the mechanism 4 to be cooled.

[0080] The cooling cycle device in this application can automatically match and adjust the cooling system 3 and the heat dissipation strategy according to the dynamic power consumption changes of each mechanism 4 to be cooled, improving the heat dissipation efficiency in the case of the same cooling capacity unit and reducing the costs and energy consumption caused by high heat dissipation requirements; moreover, the method of mainly using the centralized cooling system 32 and supplemented by the independent cooling system also reduces the heat dissipation energy consumption of the entire computer room; the free switching between the centralized and independent cooling systems 31 can effectively avoid the disadvantages of low flexibility, high operation and maintenance costs, and complex operation and maintenance caused by single-node failures, maintenance, etc.

[0081] In addition to the above cooling cycle device, this application also provides an immersion liquid-cooled cabinet, which includes the cooling cycle device of any one of the above and at least two mechanisms 4 to be cooled. The mechanism 4 to be cooled is a liquid-cooled cabinet 41, and several heating devices are arranged in the liquid-cooled cabinet 41.

[0082] During actual use, when the liquid-cooled cabinet 41 is in a normal working state, the cooling cycle device can start the normal refrigeration state, and the control system 2 controls the hydraulic control component 1 to act, enabling the liquid-cooled cabinet 41 to communicate with the corresponding centralized cooling system 32, and cooling and dissipating heat from the liquid-cooled cabinet 41 through the corresponding centralized cooling system 32; when the liquid-cooled cabinet 41 fails or needs maintenance, the cooling cycle device can start the failure or maintenance state; the control system 2 controls the hydraulic control component 1 to act, so that the liquid-cooled cabinet 41 communicates with the corresponding independent cooling system 31 to repair or maintain the liquid-cooled cabinet 41 that needs to be repaired or maintained.

[0083] Compared with only setting a centralized cooling system 32 in the immersion liquid cooling cabinet, the setting of the independent cooling system 31 in this application can effectively solve the problem of single-point failure risk. In the case of a single liquid cooling cabinet 41 failing, it is possible to specifically control the failed liquid cooling cabinet 41 to communicate with the corresponding independent cooling system 31 without affecting the normal operation of other liquid cooling cabinets 41; when it is necessary to maintain the liquid cooling cabinet 41, it is possible to control the liquid cooling cabinet 41 to be maintained to communicate with the corresponding independent cooling system 31. During the maintenance process of the liquid cooling cabinet 41 to be maintained, it does not affect the normal operation of other liquid cooling cabinets 41; moreover, during the maintenance operation process, multiple liquid cooling cabinets 41 can be maintained sequentially to avoid the situation where the entire liquid cooling cabinet 41 needs to be shut down for maintenance and affects normal work.

[0084] Compared with only setting an independent cooling system 31 in the immersion liquid cooling cabinet, in the normal working state of the liquid cooling cabinet 41 in this application, the centralized cooling system 32 is used to cool and lower the temperature of the liquid cooling cabinet 41, which can effectively reduce the number of independent cooling systems 31 set and reduce costs.

[0085] This application also provides a control method, which is applied to the cooling cycle device in any of the above items. The control method includes:

[0086] Step S1, determine whether the mechanism 4 to be cooled is in a failure or maintenance state. If so, control the liquid control component 1 to act so that the mechanism 4 to be cooled communicates with the corresponding independent cooling system 31 to repair or maintain the mechanism 4 to be repaired or maintained; if not, proceed to step S2;

[0087] In the above step S1, the working state of the mechanism 4 to be cooled can be input into the control system 2 by means of button input or manual input, or the working state of the mechanism 4 to be cooled can be directly obtained through relevant detection structures in the control system 2, which is specifically determined according to the actual situation.

[0088] Step S2, control the liquid control component 1 to act so that the mechanism 4 to be cooled communicates with the corresponding centralized cooling system 32, and cool and dissipate heat from the mechanism 4 to be cooled through the corresponding centralized cooling system 32.

[0089] In this specific embodiment, by simultaneously setting the centralized cooling system 32 and the independent cooling system 31, in the normal refrigeration state, the control system 2 controls the liquid control component 1 to connect the mechanism 4 to be cooled with the corresponding centralized cooling system 32; in the failure or maintenance state, the control system 2 controls the liquid control component 1 to connect the mechanism 4 to be cooled with the corresponding independent cooling system 31; it can effectively solve the problems in the related art that only setting an independent cooling cycle system has high costs and occupies a large space, and only setting a centralized cooling cycle system has single-point failure risks, complex operation and maintenance, and low flexibility.

[0093] Step S23, determining whether the power information is within the medium-power range. If so, controlling the liquid control component 1 to act so that the mechanism 4 to be cooled is connected to the medium-power centralized cooling system 322; if not, proceed to step S24;

[0094] Step S24, controlling the liquid control component 1 to act so that the mechanism 4 to be cooled is connected to the low-power centralized cooling system 323.

[0098] When the mechanism 4 to be cooled is in a fault state, in step S1, controlling the liquid control component 1 to act so that the mechanism 4 to be cooled is connected to the corresponding independent cooling system 31 for repairing or maintaining the mechanism 4 to be repaired or maintained includes:

[0100] Step S12: According to the fault information, determine whether the fault information requires shutdown maintenance of the to-be-cooled mechanism 4; if not, control the hydraulic control component 1 to act so that the to-be-cooled mechanism 4 is communicated with the corresponding centralized cooling system 32, and cool and dissipate heat from the to-be-cooled mechanism 4 through the corresponding centralized cooling system 32; if so, proceed to step S13;

[0101] Step S13: Control the hydraulic control component 1 to act so that the to-be-cooled mechanism 4 is communicated with the corresponding independent cooling system 31 to repair the to-be-cooled mechanism 4 that needs to be repaired or maintained;

[0104] Step S16: Control the detection mechanism to detect the liquid cooling working medium in the chamber and obtain the detection information;

[0105] Step S17: According to the detected information, determine whether the liquid cooling working medium is qualified. If not, control the filter device to start and return to step S16; if so, proceed to step S18;

[0106] Step S18: Control the hydraulic control component 1 to act so that the to-be-cooled mechanism 4 is communicated with the corresponding centralized cooling system 32.
