Description

Technical Field

[0001] This invention belongs to the field of liquid cooling fluid distribution technology, specifically relating to a liquid cooling fluid distribution system with deionized water treatment function. Background Technology

[0002] In high-efficiency heat dissipation scenarios such as electronic equipment and industrial machinery, liquid cooling systems are widely used due to their excellent heat dissipation efficiency. The purity of the coolant directly affects the operational stability and service life of the cooling system. Among them, deionized water treatment is a key link to ensure the purity of the coolant. By removing ionic impurities from the coolant, problems such as scaling and corrosion in pipelines and equipment can be avoided, thereby extending the maintenance cycle and service life of the entire cooling system. In the prior art, there are already solutions for deionized water treatment in liquid cooling systems. For example, Chinese invention patent CN222916459U discloses a cooling capacity distribution unit system with a deionization bypass. This system mainly includes a CDU forming a circulation loop and a load device. To achieve deionization treatment of the coolant, a deionization bypass is formed between the front and rear pipes of the load device. The deionization bypass consists of a flow meter and a deionization tank connected in sequence by pipes. The inlet of the flow meter is connected to the front pipe, and the outlet of the deionization tank is connected to the rear pipe. At the same time, a first switch is set on the pipe between the flow meter and the front pipe, an inlet filter is set on the pipe between the flow meter and the deionization tank, and an outlet filter is set on the pipe between the deionization tank and the rear pipe. The aforementioned existing technology, by setting inlet and outlet filters, can filter the coolant entering and leaving the deionizer, intercepting solid impurities and particulate matter in the coolant. This prevents impurities from entering the deionizer and affecting the treatment effect of the deionizing resin, and also prevents impurities from flowing into the load equipment or circulation pipeline with the coolant, causing blockages and wear. However, in actual use, the filter screen will gradually accumulate a large amount of impurities over time, causing blockage of the filter pores, which in turn affects the flow efficiency and filtration performance of the coolant. Therefore, the filter screen needs to be cleaned or replaced regularly. However, the existing filter structure design has obvious defects. The installation method of the filter screen is relatively fixed, usually using bolts or welding to connect the filter screen to the filter housing as one piece. When the filter screen needs to be cleaned, multiple fixed parts need to be disassembled with special tools. The disassembly process is cumbersome and time-consuming, which not only increases the labor intensity of operators, but also leads to the extended downtime maintenance time of the cooling system, affecting the normal operation efficiency of the equipment. In addition, the sealing structure design of the existing filter is not perfect. After long-term use or repeated disassembly and cleaning, the sealing performance between the filter housing and the end cap is prone to decline, which can easily lead to coolant leakage. This not only wastes coolant, but may also affect the normal operation of surrounding equipment and even cause safety hazards. Summary of the Invention

[0003] The purpose of this invention is to provide a liquid cooling fluid distribution system with deionized water treatment function, which solves the problems of cumbersome filter cleaning and poor sealing performance in the prior art, and ensures the stable and efficient operation of the liquid cooling system.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a liquid cooling coolant distribution system with deionized water treatment function, including a deionization bypass and a CDU and a load device forming a circulation loop. A front pipeline is provided between the CDU and the load device, and a rear pipeline is provided on the load device. The deionization bypass includes a filter and a deionization tank connected in sequence through the pipeline. The filter includes a filter body and a protective cover connected to the filter body by a locking device. A sealing gasket is provided at the bottom of the protective cover, which is tightly fitted to the opening end of the filter body. A filter screen is provided at the bottom of the protective cover, extending into the interior of the filter body, and both ends of the filter screen are fitted to the inner side of the sealing gasket.

[0005] Preferably, the locking device includes an insert plate disposed on the side surface of the protective cover, a fastening frame disposed on the side surface of the filter body, a fastening groove formed on the top of the fastening frame for the insert plate to be inserted, and a locking component disposed on the fastening frame.

[0006] Preferably, the locking component includes a threaded hole inside the fastening frame, a threaded abutment threadedly connected to the threaded hole, and a clamping plate disposed at one end of the threaded abutment and capable of pressing against the insert plate.

[0007] Preferably, the insert plate is an inverted "L" shaped structure, and the clamping plate is a cuboid structure.

[0008] Preferably, the deionization bypass further includes a first check valve and a flow meter installed on the pipeline, and the first check valve and the flow meter are spaced apart.

[0009] Preferably, the first check valve is an electromagnetic flow meter, which is electrically connected to the control system of the CDU.

[0010] Preferably, an electric ball valve switch is also provided on the deionization bypass, which is electrically connected to the control system of the CDU.

[0011] Compared with the prior art, the beneficial effects of the present invention are: The filter body and protective cover are detachably connected, and a locking device enables quick assembly and separation. The filter screen is fixedly installed on the protective cover. When cleaning the filter screen, simply loosen the protective cover using the locking device to separate it from the filter body, allowing the filter screen to be removed along with it. This eliminates the need to disassemble complex fixing components, making the operation convenient and efficient. It significantly reduces filter screen cleaning time, lowers the workload of operators, and minimizes downtime for cooling system maintenance, ensuring the normal operation efficiency of the equipment. The sealing gasket directly adheres to the opening end of the filter body, filling the gap between the protective cover and the filter body to form a reliable sealing structure. This effectively prevents coolant leakage from the connection point during filtration, avoiding coolant waste and damage to surrounding components due to moisture. It also ensures stable internal pressure within the filter, without affecting coolant flow efficiency. Attached Figure Description

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Please see Figures 1 to 5 This invention provides a liquid cooling fluid distribution system with deionized water treatment function, including a deionization bypass and a CDU1 and a load device 2 forming a circulation loop. A front pipe 11 is provided between the CDU1 and the load device 2, and a rear pipe 21 is provided on the load device 2. The CDU1 and the load device 2 form a closed loop circulation through the front pipe 11 and the rear pipe 21, ensuring that the coolant can flow stably between the core heat dissipation components and providing a basic loop guarantee for subsequent deionization treatment and cooling. The clear division of the front pipe 11 and the rear pipe 21 facilitates the precise access of the deionization bypass and ensures that the deionization treatment does not interfere with the process. For the main circulation to operate normally, the deionization bypass includes a filter and a deionization tank 6 connected sequentially through pipelines. The filter first filters impurities from the coolant, and then the deionization tank 6 removes ionic impurities, forming a dual treatment process of "filtration plus deionization." This prevents solid impurities from entering the deionization tank 6 and affecting the performance of the ion exchange resin, while ensuring the purity of the coolant after deionization treatment and extending the service life of CDU1, the load device 2, and the pipelines. The filter includes a filter body 4 and a protective cover 5 connected to the filter body 4 via a locking device. It adopts a detachable structure of "filter body 4 plus protective cover 5 plus locking device." This new structure replaces the traditional fixed connection method, allowing for quick separation of the protective cover 5 and the filter body 4 without the need for complex tools. This provides a convenient operational basis for subsequent cleaning and replacement of the filter screen 52, reducing maintenance difficulty and downtime. The bottom of the protective cover 5 is equipped with a sealing gasket 51 that fits tightly against the opening of the filter body 4. The sealing gasket 51 directly adheres to the opening of the filter body 4, filling the gap between the protective cover 5 and the filter body 4, forming a reliable sealing structure. This effectively prevents coolant leakage from the connection point during filtration, avoiding coolant waste and damage to surrounding components due to moisture, while also ensuring the internal pressure of the filter. The filter screen 52 extends into the filter body 4 at the bottom of the protective cover 5, ensuring stable power and not affecting the coolant flow efficiency. Both ends of the filter screen 52 are attached to the inner side of the sealing gasket 51. The filter screen 52 extends into the filter body 4, which can fully cover the coolant flow path and ensure that there are no dead angles for impurity interception. The two ends of the filter screen 52 are attached to the inner side of the sealing gasket 51. On the one hand, the sealing gasket 51 positions and fixes the filter screen 52 to prevent it from shifting or shaking under the flushing of coolant. On the other hand, it further optimizes the sealing effect and prevents impurities from leaking through the gap between the filter screen 52 and the sealing gasket 51, thereby improving the reliability of filtration.

[0015] In this embodiment, the locking device includes an insert plate 53 disposed on the side surface of the protective cover 5, a fastening bracket 41 disposed on the side surface of the filter body 4, a fastening groove 410 opened on the top of the fastening bracket 41 for the insert plate 53 to be inserted, and a locking component disposed on the fastening bracket 41. The device adopts a plug-in mating structure of "insert plate 53 plus fastening bracket 41 plus fastening groove 410". When installing the protective cover 5, only inserting the insert plate 53 into the fastening groove 410 is required to complete the initial positioning, without the need to repeatedly align the mounting holes, thus simplifying the assembly process. The side-mounted design of the fastening bracket 41 and the insert plate 53 reduces the space occupied by the filter body 4, making the overall structure more compact, and at the same time, it facilitates the operator to operate the locking component from the side, improving the ease of use.

[0016] In this embodiment, the locking component includes a threaded hole inside the fastening frame 41, a threaded abutment 8 threadedly connected to the threaded hole, and a clamping plate 7 disposed at one end of the threaded abutment 8 and capable of pressing against the insert plate 53. The threaded transmission structure has self-locking properties. By rotating the threaded abutment 8, the clamping plate 7 can be pushed to press against the insert plate 53, thereby achieving a firm lock between the protective cover 5 and the filter body 4. The locking force can be adjusted by the thread to adapt to the sealing requirements under different pressure conditions. The clamping plate 7 increases the contact area between the threaded abutment 8 and the insert plate 53, avoiding excessive local pressure that could cause deformation of the insert plate 53, while also improving the stability of the locking and preventing loosening of the lock due to vibration during long-term use.

[0017] In this embodiment, the insert plate 53 is an inverted "L"-shaped structure, and the clamping plate 7 is a cuboid structure. After the inverted "L"-shaped insert plate 53 is inserted into the fastening groove 410, the transverse section can form a hook-and-loop fit with the bottom of the fastening groove 410, further improving the stability of the initial positioning and preventing the protective cover 5 from accidentally falling off. The contact between the cuboid clamping plate 7 and the insert plate 53 is a surface contact, which is more uniform and stable in terms of locking compared to point contact or line contact. At the same time, the cuboid structure is easy to process, has reliable strength, and can withstand the tightening force of the threaded rod 8 for a long time without being easily damaged.

[0018] In this embodiment, the deionization bypass also includes a first check valve 31 and a flow meter 32 installed on the pipeline. The first check valve 31 and the flow meter 32 are distributed at intervals. The first check valve 31 can prevent the coolant from flowing back in the deionization bypass, avoid the mixing of treated coolant and untreated coolant, and ensure the stability of the deionization treatment effect. The flow meter 32 monitors the coolant flow rate of the deionization bypass in real time, which makes it easy for operators to grasp the treatment progress and system operating status. The two are distributed at intervals to avoid mutual interference, ensure the accuracy of their respective function detection, and optimize the pipeline layout for easy later inspection and maintenance.

[0019] In this embodiment, the first one-way valve 31 is an electromagnetic flow meter, which is electrically connected to the control system of CDU1. The electromagnetic flow meter has high measurement accuracy and fast response speed. It can accurately capture changes in coolant flow and convert them into electrical signals, which are then transmitted to the CDU1 control system to realize real-time monitoring and data feedback of flow. After being electrically connected to the control system, it can work with the automated control logic to trigger an alarm or adjust the operating status of relevant components when the flow is abnormal, thereby improving the intelligence and automation level of the system and reducing the cost of manual operation.

[0020] In this embodiment, an electric ball valve switch is also provided on the deionization bypass. This electric ball valve switch is electrically connected to the control system of CDU1. The electric ball valve switch has a rapid response and good sealing performance. Its start-up, shutdown and opening adjustment can be remotely controlled by the CDU1 control system without the need for manual on-site operation, thus improving the convenience of operation. Combined with the monitoring data of the control system, the automatic start-up and shutdown of the deionization bypass can be realized. For example, when the purity of the coolant meets the standard, the bypass is closed to reduce energy consumption, and when the purity does not meet the standard, it is automatically opened to ensure the stability of the cooling system operation and achieve a balance between energy saving and reliability.

[0021] The working principle and usage process of this invention: When CDU1 is started, the control system automatically opens the main circulation loop. The coolant flows from CDU1 into the load device 2 through the front pipe 11. After heat dissipation, it flows back through the rear pipe 21 to form an initial closed loop circulation. The CDU1 control system monitors the purity of the coolant. When the purity does not meet the preset standard, it automatically opens the electric ball valve switch, and the coolant is diverted into the deionization bypass. The coolant first enters the filter and intercepts solid impurities through the filter screen 52 that extends from the bottom of the protective cover 5 to the inside of the filter body 4. The filter screen 52 fully covers the flow path and, together with the sealing gasket 51, ensures that there are no dead angles in the interception of impurities. After filtration, the coolant flows sequentially through the first one-way valve 31 and the flow meter 32. The flow meter 32 captures the flow data in real time and transmits it to the CDU1 control system. The coolant finally enters the deion tank 6, where ion impurities are removed by ion exchange resin, completing the dual treatment of "filtration and deionization". The purified coolant, after deionization treatment, is reintroduced into the main circulation loop, mixes with the main circulation coolant, and continues to dissipate heat for the load device 2, ensuring the stability of the equipment operation.

[0022] Although embodiments of the invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
