Description

Technical Field

[0001] This utility model relates to the field of cold plate cleaning technology for liquid cooling systems, and in particular to an automated cold plate cleaning device. Background Technology

[0002] The cold plate is a key heat dissipation device in liquid cooling technology, which is directly installed on the surface of heat-generating electronic components. The cold plate has liquid channels inside, through which coolant flows to absorb and carry away the heat generated by heat-generating electronic components such as CPU, GPU, and power semiconductors, thereby achieving efficient heat transfer.

[0003] After cold-rolled steel plates are manufactured or used for a long period of time, their internal fine channels are prone to retaining metal powder, welding slag, and other processing debris, as well as contaminants such as grease, dust, and even microorganisms. These residues can clog the channels, hindering coolant flow, significantly reducing heat dissipation efficiency, and causing localized overheating, leading to equipment damage risks such as electronic component burnout or battery thermal runaway. Therefore, it is necessary to clean the liquid channels of cold-rolled steel plates to ensure their heat dissipation performance and service life. However, the currently commonly used manual cleaning methods or single-function semi-automatic cleaning methods suffer from low cleaning efficiency, poor cleaning effect, high consumable costs, and difficulty in effectively recycling cleaning wastewater, making it difficult to meet the needs of modern large-scale production.

[0023] The programmable controller is used to interface with the MES server to collect and monitor rinsing data in real time, generate a unique ID tag for each product, and execute the cleaning procedure.

[0024] The technical solution of this utility model has the following beneficial effects:

[0025] (1) Before the automated cold plate cleaning device cleans the cold plate body, or during the interval when the staff replaces the cold plate body, the control unit detects the water quality in the water storage tank through a water quality detector. When the water quality exceeds the set upper limit value, the control unit controls the drain valve to open and discharge sewage through the drain outlet.

[0026] (2) When the control unit detects that the water storage tank is at a low level, or after completing the above-mentioned sewage discharge operation (based on the feedback signal of the sewage discharge valve closing), the control unit controls the replenishment pump 9 to start, replenishing the water filtered from the sewage tank into the water storage tank. In addition, the control unit can also control the water injection valve 1 to open based on the feedback from the water level detector (such as when the water filtered from the sewage tank is insufficient to fill the water storage tank), allowing pure water to be injected into the water storage tank through the water source interface and the water injection valve. When the water level detector detects that the water storage tank 3 is at a high level, the water injection valve 1 is immediately closed.

[0027] (3) When the above-mentioned sewage discharge operation is completed and the water in the storage tank is sufficient, the staff can simultaneously install ten cold plate bodies to be rinsed into the cold plate cleaning structure, so that the liquid flow channel inside the cold plate body becomes part of the forward primary rinsing channel, the forward rinsing circulation channel, the reverse rinsing circulation channel and the purging cleaning channel, thereby cleaning ten cold plate bodies simultaneously through the automated cold plate cleaning device.

[0028] (4) The following is the complete process of cleaning the cold plate body by the automated cold plate cleaning device: First, the cold plate body is rinsed for a certain period of time using the forward initial rinsing passage. The wastewater discharged from the forward initial rinsing is discharged into the wastewater tank through the drain valve. Second, the cold plate body is rinsed for a certain period of time using the forward rinsing circulation passage. The water discharged from the rinsing is circulated into the water storage tank through the pipeline. Third, the cold plate body is rinsed for a certain period of time using the reverse rinsing circulation passage. The water discharged from the rinsing is also circulated into the water storage tank through the pipeline. Finally, the water inside the cold plate body is blown into the wastewater tank using the purging cleaning passage to empty and dry the liquid flow channel of the cold plate body. After purging for a certain period of time, the operator can remove the cold plate body and replace it with a new cold plate body to be rinsed.

[0029] (5) During the rinsing of the cold plate body using both forward and reverse rinsing circulation modes, the water discharged from the cold plate body circulates through pipes to the water storage tank. At this time, the pH and conductivity of the water are measured by pH and conductivity sensors in the pipes. The control unit then processes and analyzes the pH and conductivity, and uses the processing and analysis results (mainly the difference between the pH and conductivity before cleaning the cold plate body and the currently collected pH and conductivity) to help determine whether to switch modes, i.e., switch the forward rinsing circulation mode to the reverse rinsing circulation mode, or switch the reverse rinsing circulation mode to the purging cleaning mode. In addition, the control unit can also use the pH and conductivity to help determine the degree of cleaning completion, thereby helping to confirm whether the cleaning has been completed.

[0030] (6) Compared with manual or semi-automatic cleaning methods, this design can complete the corresponding rinsing operation through the cooperation of control unit, detection component and cleaning component after the cold plate body is installed. After rinsing is completed, the cold plate body is removed and replaced with a new cold plate body to be rinsed. The degree of automation is higher, the cleaning efficiency is higher and the cleaning effect is better. By setting up a sewage tank and replenishment pump, water loss can be reduced and sewage can be recycled, thereby meeting the needs of modern large-scale production. Attached Figure Description

[0039] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0040] This invention proposes an automated cold plate cleaning device.

[0041] like Figures 1 to 2As shown in Embodiment 1 of this utility model, the automated cold plate cleaning device includes a cleaning unit and a control unit. The cleaning unit includes several pipes and a water source interface 14, a flushing pump 4, a forward and reverse flushing assembly, and a drain assembly connected sequentially through the pipes. The input end of the water source interface 14 is connected to a cleaning water source, and the output end of the drain assembly is connected to a drain outlet 16. Specifically, the forward and reverse flushing assembly includes a cold plate cleaning structure 15 and multiple cold plate flushing valves. The multiple cold plate flushing valves, the cold plate cleaning structure 15, and the pipes form a forward flushing passage and a reverse flushing passage. The control unit is electrically connected to the flushing pump 4 and the cold plate flushing valves.

[0042] When rinsing the cold plate body, the operator can install the cold plate body to be rinsed in the cold plate cleaning structure 15, so that the liquid flow channels inside the cold plate body are connected to the rinsing pump 4 and the drainage assembly, thus becoming part of the forward rinsing path and the reverse rinsing path. Then, the control unit executes the cleaning program, thereby controlling the rinsing pump 4 and the cold plate rinsing valve to open or close according to a certain pattern, so as to perform forward and reverse rinsing of the liquid flow channels inside the cold plate body through the forward rinsing path and the reverse rinsing path. The residue discharged during rinsing can be discharged through the drainage assembly to the drain port 16 for appropriate treatment. Compared with manual or semi-automatic cleaning methods, this design, after the cold plate body is installed, can complete the corresponding rinsing operation in cooperation with the control unit and the cleaning assembly until the rinsing is completed, and then remove the cold plate body and replace it with a new cold plate body to be rinsed. The degree of automation is higher, the cleaning efficiency is higher, and the cleaning effect is better.

[0043] In this embodiment, the automated cold plate cleaning device further includes a detection unit, which comprises several detection sensors disposed within the cleaning unit. The control unit is electrically connected to the detection sensors. Specifically, the detection sensors are a flow meter 5, a pH sensor, and a conductivity sensor. Further, the flow meter 5 is disposed between the flushing pump 4 and the forward and reverse flushing assembly to measure the pumping flow rate of the flushing pump 4. The control unit adjusts the frequency of the flushing pump 4 based on the measurement data from the flow meter 5 until it stabilizes at its rated operating condition. Once the flushing pump 4 stabilizes at its rated operating condition, it maintains a constant pumping frequency until the control unit issues a new frequency adjustment command based on new measurement data from the flow meter 5 or new cleaning parameters input by the operator. It is worth noting that the rated operating condition of the flushing pump 4 is determined by actual usage conditions and will not be elaborated upon in this embodiment.

[0044] Additionally, the pH sensor and conductivity sensor are located between the forward and reverse rinsing components and the drainage component, specifically within the pipe connecting the cold plate cleaning structure 15 to the water storage tank 3 described below. When water flows out from the liquid flow channel of the cold plate body and circulates through the pipe to the water storage tank 3, the pH sensor and conductivity sensor measure the pH value and conductivity of the water. The control unit then processes and analyzes the pH value and conductivity, and uses the processing and analysis results to help determine whether to execute the corresponding cleaning procedure. The corresponding cleaning procedure is as follows: controlling the opening or closing of the corresponding cold plate rinsing valve, air blowing valve 8, and drainage valve 12 to perform switching operations for forward circulation rinsing, reverse circulation rinsing, and purging cleaning; and after purging cleaning is completed, notifying the staff to replace the cold plate body via voice or other means.

[0045] Optionally, the automated cold plate cleaning device also includes an air blowing valve 8 and an air source, with the control unit electrically connected to the air blowing valve 8. In this embodiment, the air source, air blowing valve 8, cold plate cleaning structure 15, drain valve 12, and wastewater tank 13 are sequentially connected via pipelines to form a purging cleaning path. Cleaning the cold plate body using this purging cleaning path is the purging cleaning mode. After the cold plate body completes forward and reverse rinsing operations, the control unit can open the air blowing valve 8 and drain valve 12 to purge the water inside the cold plate body into the wastewater tank 13 to drain and dry the liquid flow channels of the cold plate body, facilitating subsequent processes after cleaning.

[0046] Optionally, the cleaning unit also includes a water injection valve 1 and a water storage tank 3. The water storage tank 3 includes a water volume detector, a water quality analyzer, and a drain valve 2. The water volume detector and the water quality analyzer are both installed inside the water storage tank 3. The drain valve 2 is connected to the drain outlet 16. The control unit is electrically connected to the water injection valve 1, the water quality analyzer, and the drain valve 2, respectively. The drainage assembly includes a drain valve 12, a wastewater tank 13, and a replenishment pump 9. A filter structure is provided inside the wastewater tank 13. The control unit is electrically connected to the drain valve 12 and the replenishment pump 9. In this embodiment, the water source interface 14 is connected to a pure water source. Pure water is input into the water storage tank 3 through the water source interface 14 for temporary storage and use for rinsing the cold plate body. The drain outlet 16 can be connected to a wastewater treatment device or wastewater treatment station as needed.

[0047] like Figure 1As shown, water source interface 14, water injection valve 1, water storage tank 3, flushing pump 4, flow meter 5, first forward flushing valve 6, cold plate cleaning structure 15, drain valve 12, and wastewater tank 13 are connected sequentially through pipelines to form the following forward initial flushing path; furthermore, wastewater tank 13, replenishment pump 9, and water storage tank 3 are connected sequentially through pipelines, and the filtered wastewater in wastewater tank 13 can be pumped to water storage tank 3 for recycling by replenishment pump 9. Further, water source interface 14, water injection valve 1, water storage tank 3, flushing pump 4, flow meter 5, first forward flushing valve 6, cold plate cleaning structure 15, second forward flushing valve 11, and water storage tank 3 are connected sequentially through pipelines to form the following forward flushing circulation path. Similarly, water source interface 14, water injection valve 1, water storage tank 3, flushing pump 4, flow meter 5, first reverse flushing valve 7, cold plate cleaning structure 15, second reverse flushing valve 10, and water storage tank 3 are connected sequentially through pipelines to form the following reverse initial flushing path.

[0048] In this embodiment, the control unit monitors the water quality in the storage tank 3 in real time using a water quality detector. When the water quality exceeds the set upper limit, the control unit controls the drain valve 2 to open and discharge wastewater through the drain port 16. Additionally, the control unit monitors the water level in the storage tank 3 in real time using a water level detector. When the storage tank 3 is detected to be at a low level, or after the aforementioned discharge operation is completed (based on the feedback signal of the drain valve 2 closing), the control unit controls the replenishment pump 9 to open and replenish the storage tank 3 with the water filtered from the wastewater tank 13. Furthermore, the control unit can also control the water injection valve 1 to open based on feedback from the water level detector (e.g., the water filtered from the wastewater tank 13 is insufficient to fill the storage tank 3), allowing pure water to be injected into the storage tank 3 through the water source interface 14 and the water injection valve 1. When the water level detector detects that the storage tank 3 is at a high level, the water injection valve 1 is immediately closed.

[0049] It is worth noting that the sewage discharge operation must be performed before cleaning the cold plate body, or during the interval when the staff replaces the cold plate body. The liquid replenishment operation can be performed during the cleaning of the cold plate (i.e., in the forward initial flush mode, forward flush circulation mode, reverse flush circulation mode, or purging cleaning mode).

[0050] Optionally, the multiple cold plate rinsing valves are distributed as a first forward rinsing valve 6, a second forward rinsing valve 11, a first reverse rinsing valve 7, and a second reverse rinsing valve 10. The control unit is electrically connected to the first forward rinsing valve 6, the second forward rinsing valve 11, the first reverse rinsing valve 7, and the second reverse rinsing valve 10, respectively, so that when the corresponding cleaning program is executed, the first forward rinsing valve 6, the second forward rinsing valve 11, the first reverse rinsing valve 7, and the second reverse rinsing valve 10 are opened or closed respectively.

[0051] Specifically, the flushing pump 4, the first forward flushing valve 6 (open), the cold plate cleaning structure 15, and the second forward flushing valve 11 (open) are connected in sequence to form a forward flushing circulation path. The water in the water storage tank 3 is used to flush the cold plate body in a forward direction along the forward flushing circulation path and circulates back into the water storage tank 3, which is the forward flushing circulation mode.

[0052] Furthermore, the flushing pump 4, the first forward flushing valve 6 (open), the cold plate cleaning structure 15, the drain valve 12 (open), and the sewage tank 13 are connected in sequence to form a forward primary flushing passage. The water in the water storage tank 3 is used to flush the cold plate body in a forward manner along the forward primary flushing passage and is discharged into the sewage tank 13 (the sewage is then filtered by the filter structure of the sewage tank 13 and pumped into the water storage tank 3 by the replenishment pump 9), which is the forward primary flushing mode.

[0053] Furthermore, the flushing pump 4, the first backflushing valve 7 (open), the cold plate cleaning structure 15, and the second backflushing valve 10 (open) are connected in sequence to form a backflushing circulation path. The water in the water storage tank 3 backflushes the cold plate body along the backflushing circulation path and circulates back into the water storage tank 3, which is the backflushing circulation mode.

[0054] In this embodiment, when rinsing the cold plate body, firstly, a forward initial rinsing channel is used to perform a forward initial rinsing of the cold plate body for a certain period of time. The wastewater discharged from the forward initial rinsing is discharged into the wastewater tank 13 through the drain valve 12. Secondly, a forward circulating rinsing channel is used to perform a forward circulating rinsing of the cold plate body for a certain period of time. The water discharged from the rinsing is circulated through a pipe into the water storage tank 3. Thirdly, a reverse circulating rinsing channel is used to perform a reverse circulating rinsing of the cold plate body for a certain period of time. The water discharged from the rinsing is also circulated through a pipe into the water storage tank 3. Finally, a purging cleaning channel is used to purge the water inside the cold plate body into the wastewater tank 13 to empty and dry the liquid flow channels of the cold plate body. After purging for a certain period of time, the operator can remove the cold plate body and replace it with a new cold plate body to be rinsed. It is worth noting that during the process of the discharged water circulating to the water storage tank 3, the pH value and conductivity of the water are measured by pH sensor and conductivity sensor. Then, the control unit processes and analyzes the pH value and conductivity, and uses the processing and analysis results to help determine whether to execute the corresponding cleaning program (mainly based on the preset cleaning time).

[0055] In other embodiments, the installation position of the corresponding valves can be adjusted to form a reverse primary flushing passage so that the cold plate body can be reversed and initially flushed before reverse circulation flushing is performed using the reverse primary flushing passage. The wastewater discharged from the reverse primary flushing is discharged into the wastewater tank 13 through the drain valve 12.

[0056] Optionally, the aforementioned cold plate cleaning structure 15 includes multiple branch pipes, with the cold plate body to be rinsed installed in each branch pipe. Specifically, the cold plate cleaning structure 15 includes ten branch pipes (the number of branch pipes can also be eight, twelve, or other numbers). Workers can simultaneously install ten cold plate bodies to be rinsed, making the liquid flow channels inside the cold plate body part of the aforementioned forward rinsing circulation path, forward initial rinsing path, and reverse rinsing circulation path, thereby simultaneously rinsing ten cold plate bodies.

[0057] like Figure 2 As shown, the control unit includes a main power supply, a main control switch, an AC contactor, a programmable logic controller (PLC), a flushing pump, a solid-state relay, a replenishment pump, a touch screen, a DC power supply, a valve relay, a frequency converter, and a switch. Specifically, the switch has a first communication interface, through which the PLC and the touch screen are electrically connected, and the PLC also interfaces with the MES server via the switch. Additionally, the touch screen has a second communication interface, through which staff can download programs or export / import data. Furthermore, the connection relationship and function of the flushing pump and the replenishment pump have been described above, while the main power supply, main control switch, AC contactor, solid-state relay, and DC power supply are all mature existing technologies, and their principles and functions will not be elaborated further in this embodiment.

[0058] In this embodiment, the frequency converter is electrically connected to the programmable controller and the flushing pump respectively. The frequency converter is used to adjust the pumping frequency of the flushing pump according to the PID instruction of the programmable controller.

[0059] The valve relay module is electrically connected to the programmable controller and the aforementioned water injection valve, drain valve, first forward flush valve, first reverse flush valve, air blowing valve, second reverse flush valve, second forward flush valve, and drain valve. The valve relay module is used to control the opening or closing of the aforementioned valves according to the instructions of the programmable controller.

[0060] The touchscreen is electrically connected to the programmable controller via a switch. It serves as an interactive window for users to set cleaning parameters and displays real-time flow fluctuations, pH / conductivity trends, and valve status. Furthermore, operators can monitor the monitoring data in real-time via the touchscreen, which displays the data as curves, showing time, flow rate, and real-time cleaning results. Additionally, operators can store, export, and query historical data via the touchscreen.

[0061] The aforementioned programmable controller is used to execute the cleaning process and also to interface with the MES server to collect and monitor rinsing data in real time, generate a unique ID tag for each product, and achieve full traceability.

[0062] Specifically, the working principle and process of this utility model are as follows:

[0063] (1) Before the automated cold plate cleaning device cleans the cold plate body, or during the interval when the staff replaces the cold plate body, the control unit detects the water quality in the water storage tank 3 through the water quality detector. When the water quality exceeds the set upper limit value, the control unit controls the drain valve 2 to open and discharge sewage through the drain port 16.

[0064] (2) When the control unit detects that the water storage tank 3 is at a low level, or after the above-mentioned sewage discharge operation is completed (based on the feedback signal of the closing of the sewage discharge valve 2), the control unit controls the replenishment pump 9 to start, replenishing the water filtered from the sewage tank 13 into the water storage tank 3. In addition, the control unit can also control the water injection valve 1 to open according to the feedback from the water level detector (such as when the water filtered from the sewage tank 13 is insufficient to fill the water storage tank 3), allowing pure water to be injected into the water storage tank 3 through the water source interface 14 and the water injection valve 1. When the water level detector detects that the water storage tank 3 is at a high level, the water injection valve 1 is immediately closed.

[0065] (3) When the above-mentioned sewage discharge operation is completed and the water in the water tank 3 is sufficient, the staff can simultaneously install ten cold plate bodies to be rinsed in the cold plate cleaning structure 15, so that the liquid flow channel inside the cold plate body becomes part of the forward primary rinsing channel, the forward rinsing circulation channel, the reverse rinsing circulation channel and the purging cleaning channel, thereby cleaning ten cold plate bodies simultaneously through the automated cold plate cleaning device.

[0066] (4) The following is the complete process of cleaning the cold plate body using the automated cold plate cleaning device: First, the cold plate body is rinsed for a certain period of time using the forward initial rinsing channel. The wastewater discharged from the forward initial rinsing is discharged into the wastewater tank 13 through the drain valve 12. Second, the cold plate body is rinsed for a certain period of time using the forward rinsing circulation channel. The water discharged from the rinsing is circulated into the water storage tank 3 through the pipeline. Third, the cold plate body is rinsed for a certain period of time using the reverse rinsing circulation channel. The water discharged from the rinsing is also circulated into the water storage tank 3 through the pipeline. Finally, the water inside the cold plate body is blown into the wastewater tank 13 using the purging cleaning channel to empty and dry the liquid flow channels of the cold plate body. After purging for a certain period of time, the operator can remove the cold plate body and replace it with a new cold plate body to be rinsed.

[0067] (5) During the rinsing of the cold plate body using both forward and reverse rinsing circulation modes, the water discharged from the cold plate body circulates through pipes to the water storage tank 3. At this time, the pH and conductivity of the water are measured by pH and conductivity sensors in the pipes. The control unit then processes and analyzes the pH and conductivity, and uses the processing and analysis results (mainly the difference between the pH and conductivity before cleaning the cold plate body and the currently collected pH and conductivity) to help determine whether to switch modes, i.e., switch the forward rinsing circulation mode to the reverse rinsing circulation mode, or switch the reverse rinsing circulation mode to the purging cleaning mode. In addition, the control unit can also use the pH and conductivity to help determine the degree of cleaning completion, thereby helping to confirm whether the cleaning has been completed.

[0068] (6) Compared with manual or semi-automatic cleaning methods, this design can complete the corresponding rinsing operation through the cooperation of control unit, detection component and cleaning component after the cold plate body is installed. After rinsing is completed, the cold plate body is removed and replaced with a new cold plate body to be rinsed. The degree of automation is higher, the cleaning efficiency is higher and the cleaning effect is better. By setting up wastewater tank 13 and replenishment pump 9, water loss can be reduced and wastewater can be recycled, thereby meeting the needs of modern large-scale production.

[0069] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
