Description
Technical Field
[0001] This utility model belongs to the field of liquid cooling pipeline technology, and more specifically, it relates to a liquid cooling pipeline with impurity removal function. Background Technology
[0002] Immersion liquid cooling systems are gaining popularity due to their high heat dissipation efficiency, precise temperature control, effective suppression of thermal runaway, and fire suppression capabilities, and are gradually becoming a major area of future development. In immersion liquid cooling systems, since the immersion fluid is in direct contact with the battery cells, the safety and performance of the immersion fluid directly affect the safety of the immersion energy storage system.
[0003] In immersion liquid cooling systems, the immersion fluid is used in large volumes and quantities. During prolonged immersion and operation, impurities are generated in contact with various components. These impurities may affect the system's conductivity and insulation performance, threatening system safety. Currently, many immersion liquid cooling systems still use the original piping from the original system. This piping cannot effectively remove impurities generated during operation, causing the immersion fluid to carry increasing amounts of impurities during circulation, further threatening the safety of the immersion system. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a liquid cooling pipe with impurity removal function is provided, including a first liquid cooling pipe, a diversion valve, a filter, a U-shaped pipe, a shut-off valve, and a second liquid cooling pipe connected end to end. The end of the first liquid cooling pipe away from the diversion valve is used to connect to a liquid cooling unit. The U-shaped pipe is U-shaped and used to store impurities. The end of the second liquid cooling pipe away from the shut-off valve is used to connect to an immersion chamber.
[0006] The filter is adapted to filter impurities and prevent impurities from entering the first liquid cooling pipe. The diversion valve is adapted to lead the immersion liquid in the U-shaped pipe to the first liquid cooling pipe. The shut-off valve is adapted to control the flow of immersion liquid between the U-shaped pipe and the second liquid cooling pipe. Impurities in the immersion liquid inside the immersion tank flow into the U-shaped pipe after passing through the shut-off valve. The impurities in the immersion liquid are removed by discharging the impurities in the U-shaped pipe.
[0007] In one possible implementation, the second liquid cooling pipe is connected to a conductivity meter adapted to measure the conductivity of the immersion liquid inside the second liquid cooling pipe in real time.

One end of each of the multiple branch pipes is connected to the second liquid cooling pipe, and the other end is used to connect to multiple immersion tanks.
[0009] In one possible implementation, the conductivity meter is electrically connected to a battery monitoring and management system. The battery monitoring and management system receives conductivity parameter information measured by the conductivity meter. The battery monitoring and management system is equipped with a conductivity alarm threshold. When the conductivity of the immersion liquid measured by the conductivity meter exceeds the conductivity alarm threshold, the battery monitoring and management system issues an alarm signal.
[0010] In one possible implementation, the liquid-cooled pipe with impurity removal function further includes a valve, one end of which is connected to the U-shaped pipe and the other end of which is connected to a flexible hose. The flexible hose is used to discharge impurities from the U-shaped pipe, and the valve is used to control the opening and closing of the flexible hose.

[0012] In one possible implementation, both the first liquid cooling pipe and the second liquid cooling pipe are detachably connected to a connector, which is used to fix the first liquid cooling pipe and the second liquid cooling pipe.
[0013] In one possible implementation, the connector is a snap-fit or a clamp.
[0014] In one possible implementation, the second liquid cooling pipe is evenly connected to a plurality of tee fittings along its extension direction, and one end of each of the plurality of tee fittings is connected to one end of a plurality of branch pipes.
[0015] In one possible implementation, both the end of the branch pipe away from the second liquid cooling pipe and the end of the first liquid cooling pipe away from the diversion valve are connected to pipe fittings.
[0016] The beneficial effects of the liquid cooling pipe with impurity removal function provided by this utility model are as follows: Compared with the prior art, the liquid cooling pipe with impurity removal function of this utility model includes a first liquid cooling pipe, a diversion valve, a filter, a U-shaped pipe, a shut-off valve, and a second liquid cooling pipe connected end to end.

[0023] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] Please refer to the following: Figures 1 to 3 This invention provides a liquid-cooled pipe with impurity removal function. The liquid-cooled pipe with impurity removal function includes a first liquid-cooled pipe 1, a diversion valve 2, a filter 3, a U-shaped pipe 4, a shut-off valve 5, and a second liquid-cooled pipe 6 connected end-to-end. The end of the first liquid-cooled pipe 1 away from the diversion valve 2 is connected to a liquid-cooling unit. The U-shaped pipe 4 is U-shaped and used to store impurities. The end of the second liquid-cooled pipe 6 away from the shut-off valve 5 is connected to an immersion chamber. The filter 3 is adapted to filter impurities and prevent them from entering the first liquid-cooled pipe 1. The diversion valve 2 is adapted to lead the immersion liquid in the U-shaped pipe 4 to the first liquid-cooled pipe 1. The shut-off valve 5 is adapted to control the flow of immersion liquid between the U-shaped pipe 4 and the second liquid-cooled pipe 6. Impurities in the immersion liquid inside the immersion chamber flow into the U-shaped pipe 4 after passing through the shut-off valve 5. The impurities in the immersion liquid are removed by discharging the impurities from the U-shaped pipe 4.
[0025] This utility model provides a liquid cooling pipe with impurity removal function. Compared with the prior art, the shut-off valve 5 can trap impurities in the U-shaped pipe 4, the diversion valve 2 can divert the immersion liquid in the U-shaped pipe 4 to the first liquid cooling pipe 1, the filter 3 can filter impurities, and the discharge of impurities in the U-shaped pipe 4 can achieve the effect of removing impurities from the immersion liquid. This solves the technical problem that the pipes currently in use do not have the function of cleaning impurities, which threatens the safety of the immersion liquid cooling system. It can remove impurities in the immersion liquid and prevent it from affecting the safety of the immersion liquid cooling system.
[0026] In existing technologies, the immersion fluid is used in large quantities and is expensive. When there are many impurities in the immersion fluid, the entire fluid needs to be replaced, resulting in material waste and high maintenance costs. This application addresses this by incorporating a diversion valve 2, a filter 3, a U-shaped pipe 4, and a shut-off valve 5. This allows impurities in the immersion fluid to accumulate in the U-shaped pipe 4 for temporary storage and discharge, facilitating targeted cleaning of impurities. Only the portion containing impurities needs replacement, extending the immersion fluid's lifespan without material waste or increased maintenance costs, thus reducing the overall maintenance cost of the liquid cooling system. During impurity removal, a portion of the immersion fluid is allowed to drain out of the U-shaped pipe 4 along with the impurities. While this may not completely remove all impurities, it effectively removes most of them. The remaining small amount of impurities will not affect the overall quality and condition of the immersion fluid, including its conductivity. The purpose of setting up the U-shaped pipe 4 is: the U-shaped pipe 4 can retain a certain amount of impurities, allowing them to be temporarily stored inside. By making the bottom or top height of the U-shaped pipe 4 different from the height of the second liquid cooling pipe 6, the impurities can be retained. The length of the U-shaped pipe 4 can be reasonably selected according to actual needs.
[0027] In some embodiments, please refer to Figure 1 and Figure 3 The second liquid cooling pipe 6 is connected to a conductivity meter 7, which is suitable for real-time measurement of the conductivity of the immersion fluid inside the second liquid cooling pipe 6. Currently, the verification of immersion fluids mostly involves periodically extracting the immersion fluid from the immersion liquid cooling system for testing. This testing process is cumbersome, cannot monitor the immersion fluid status in real time, and also poses safety risks. In this application, by installing the conductivity meter 7 inside the second liquid cooling pipe 6, the conductivity of the immersion fluid can be measured in real time, thereby determining the quality and status of the immersion fluid. The testing process is simpler, reducing safety risks. The conductivity meter 7 is placed inside the second liquid cooling pipe 6. The selection of the conductivity meter 7 should be based on the inner diameter of the second liquid cooling pipe 6 to ensure that the conductivity meter 7 can be installed or fixed inside the second liquid cooling pipe 6. Specifically, connecting parts, such as screws, can be installed inside the second liquid cooling pipe 6 to fix the conductivity meter 7 inside. Both the first liquid cooling pipe 1 and the second liquid cooling pipe 6 are L-shaped. The filter 3 in this application is a pipe fitting with an internal filter screen, which can filter impurities and prevent impurities from flowing into the first liquid cooling pipe 1. The diversion valve 2 can also control the flow or shut-off of the immersion liquid.
[0028] Specifically, the conductivity measuring instrument 7 or its measuring end is placed inside the second liquid cooling pipe 6, which can measure the conductivity of the immersion liquid in real time and export the measured information to the outside of the second liquid cooling pipe 6, that is, the measured conductivity can be observed outside the second liquid cooling pipe 6.
[0029] In some embodiments, please refer to Figure 1 and Figure 3 The conductivity meter 7 is connected to the other end of the second liquid cooling pipe 6. Multiple branch pipes 8 are evenly distributed along the side of the second liquid cooling pipe 6, with one end connected to the second liquid cooling pipe 6 and the other end connected to multiple immersion chambers. The branch pipes 8 are arranged side-by-side with intervals, and do not affect the setting of the conductivity meter 7. The length of the branch pipes 8 can be adjusted according to actual needs. The diameter of the branch pipes 8 can be the same as or close to the diameter of the first liquid cooling pipe 1. When impurities enter the U-shaped pipe 4, the shut-off valve 5 can be closed to prevent impurities from entering the second liquid cooling pipe 6, at which point the impurities can be discharged.
[0030] In some embodiments, please refer to Figure 1 and Figure 3The conductivity meter 7 is electrically connected to the battery monitoring and management system 9. The battery monitoring and management system 9 receives conductivity parameter information measured by the conductivity meter 7. The battery monitoring and management system 9 is equipped with a conductivity alarm threshold. When the conductivity of the immersion fluid measured by the conductivity meter 7 exceeds the conductivity alarm threshold, the battery monitoring and management system 9 issues an alarm signal. The battery monitoring and management system 9 is a BMS system. The conductivity meter 7 is electrically connected to the battery monitoring and management system 9 via a wiring harness. The wiring harness can pass through the second liquid cooling pipe 6 and is sealed to prevent leakage of the immersion fluid. The conductivity parameters can be exported to the battery monitoring and management system 9 via the wiring harness for easy viewing by staff and to provide parameter support for subsequent measures. The conductivity alarm threshold is preset on the battery monitoring and management system 9 and can be adjusted reasonably according to actual conditions. When the conductivity parameter measured by the conductivity meter 7 exceeds the preset conductivity alarm threshold, the battery monitoring and management system 9 will issue an alarm signal to remind staff to replace the immersion fluid in time to ensure the safety of the liquid cooling system.
[0031] Preferably, the battery monitoring and management system 9 is located near the conductivity measuring instrument 7. It has a display screen, a threshold setting module, an alarm module, and a controller. The display screen can display the measured conductivity parameters of the immersion liquid, the alarm module can issue an alarm signal, and the threshold setting module can set the conductivity alarm threshold appropriately.
[0032] In order to remove impurities from the U-shaped pipe 4, in some embodiments, please refer to Figure 2 The liquid-cooled pipeline with impurity removal function also includes a valve 10. One end of the valve 10 is connected to the U-shaped pipeline 4, and the other end is connected to a flexible hose 11. The flexible hose 11 is used to discharge impurities from the U-shaped pipeline 4, and the valve 10 is used to control the opening and closing of the flexible hose 11. After opening the valve 10, impurities and a portion of the immersion liquid in the U-shaped pipeline 4 can be discharged into the flexible hose 11. The end of the flexible hose 11 away from the valve 10 can be connected to a discharge tank or an impurity tank (a container for storing discharged impurities and immersion liquid), which can then guide the impurities and a portion of the immersion liquid into the discharge tank. After the impurities are discharged, the valve 10 can be closed, at which point the immersion liquid in the U-shaped pipeline 4 will no longer flow out.
[0033] In some embodiments, please refer to Figures 1 to 3 The diameter of the first liquid cooling pipe 1 is smaller than that of the U-shaped pipe 4, and the diameter of the U-shaped pipe 4 is the same as that of the second liquid cooling pipe 6. In specific use, the appropriate diameters of the first liquid cooling pipe 1, the U-shaped pipe 4, and the second liquid cooling pipe 6 should be selected according to the actual application scenario, the compatibility with the diversion valve 2, the shut-off valve 5, and the flow rate of the immersion liquid.
[0034] To ensure an effective and stable connection between the first liquid cooling pipe 1 and the second liquid cooling pipe 6 and the immersion liquid cooling system, in some embodiments, please refer to... Figure 1 Both the first liquid cooling pipe 1 and the second liquid cooling pipe 6 are detachably connected to connectors 12, which are used to fix the first liquid cooling pipe 1 and the second liquid cooling pipe 6. By using connectors 12, the first liquid cooling pipe 1 and the second liquid cooling pipe 6 can be fixed to the immersion liquid cooling system or other objects, preventing movement of the first liquid cooling pipe 1 and the second liquid cooling pipe 6 during operation, effectively ensuring operational stability and quality. Multiple connectors 12, evenly or at equal intervals along the extension direction of the first liquid cooling pipe 1 and the second liquid cooling pipe 6, can effectively fix the first liquid cooling pipe 1 and the second liquid cooling pipe 6.
[0035] Preferably, in this embodiment, the connector 12 is a buckle or a clamp. Of course, other structures or forms of connector 12 can also be selected, which can facilitate detachable connection with immersion liquid cooling systems or other objects, making the connection operation more convenient and improving the efficiency of connection and fixed installation.
[0036] To achieve the connection between the second liquid cooling pipe 6 and multiple branch pipes 8, in some embodiments, please refer to... Figure 1 The second liquid cooling pipe 6 is evenly connected to multiple tee fittings 13 along its extension direction. One end of each tee fitting 13 is connected to one end of a branch pipe 8. This can be seen as dividing the second liquid cooling pipe 6 into multiple shorter sections. Along the extension direction of the second liquid cooling pipe 6, these sections and tee fittings 13 are alternately arranged, with one tee fitting 13 installed between adjacent sections. This forms a combined structure of the second liquid cooling pipe 6 and multiple tee fittings 13, creating a unified structure that facilitates connection to the branch pipes 8. Each tee fitting 13 has three ports. Two coaxial ports are connected to the adjacent ends of two adjacent sections, and the other port of the tee fitting 13 is connected to one port of a branch pipe 8. In this embodiment, there are five branch pipes 8, and therefore five tee fittings 13, connected in a one-to-one correspondence. The tee fittings 13 and branch pipes 8 must be mutually compatible.
[0037] In some embodiments, please refer to Figure 1 The branch pipe 8, at the end furthest from the second liquid cooling pipe 6, and the first liquid cooling pipe 1, at the end furthest from the diversion valve 2, are both connected to pipe fittings 14. Pipe fittings 14 can communicate with the submerged tank and with the liquid cooling unit, ensuring that the submerged liquid does not leak when flowing.
[0038] The main beneficial effects of this application are: 1) By setting up a diversion valve 2, a filter 3, a U-shaped pipe 4, and a shut-off valve 5, impurities generated during operation are removed from the liquid cooling system, ensuring the service life and operational safety of the immersion liquid and reducing maintenance costs. 2) By using a conductivity meter 7 to monitor and control the conductivity signal of the immersion liquid in real time, the safety of the immersion liquid can be determined in real time, ensuring the safety of the liquid cooling system during operation.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
