Description

Technical Field

[0001] This invention relates to the field of radiator technology, and more particularly to a water leakage protection device for a water-cooled radiator in a computer host. Background Technology

[0002] When using a home computer, the CPU is typically cooled by either an air cooler or a liquid cooler. Liquid coolers primarily utilize coolant in the heat pipes to cool the heatsink, and a pump circulates the coolant through the heat pipes, thus cooling the heatsink. While liquid coolers offer better cooling than air coolers, the connections in the circulation pipes are prone to leakage after prolonged use. If a liquid cooler leaks, the dripping water may cause a short circuit in the motherboard or other hardware.

[0003] In existing water-cooled chassis structures, most only have fixed leak detection or simple collection structures at key locations in the circulation piping. This limited detection range often makes it difficult to pinpoint specific leaks promptly and accurately. When even a small leak occurs, the coolant can easily spread along the piping or structural surfaces, directly contacting core components such as the motherboard and power supply, causing potential short circuits and corrosion. Furthermore, traditional solutions lack proactive containment or sealing measures for leaks, typically requiring only a reactive shutdown. The leak's spread during this process already negatively impacts equipment safety and stability. Summary of the Invention

The baffle is made of a material that can be magnetically attracted. Multiple first springs are connected between the baffle and the inner wall of the protective housing.

The bracket is magnetically connected to the side wall of the chassis through the second electromagnet. A through groove is provided in the middle section of the bracket, and two rubber sheets are provided inside the through groove. A rotating rod is installed on the side of the bracket away from the chassis, and the rotating rod is driven to rotate by a first motor fixedly installed at the end of the bracket.

[0009] Preferably, both ends of the bracket are provided with cavities, and a second spring is provided in the cavity. The end of the second spring near the chassis is connected to a stop block, and the length of the second spring in its normal state is greater than the depth of the cavity.

[0010] Preferably, both ends of the bracket are covered with rubber pads to prevent damage to the bracket when it falls.

[0011] Preferably, the position adjustment mechanism includes a first ball screw horizontally installed inside the chassis, a second ball screw arranged longitudinally mounted on the moving end of the first ball screw via a support plate, a first electric telescopic rod arranged horizontally fixedly connected to the moving end of the second ball screw, and the telescopic end of the first electric telescopic rod fixedly connected to the folding plate.

[0012] Preferably, the driving mechanism includes a third motor, an arc-shaped rack, and a gear.

[0014] Preferably, a plastic film is rolled up inside the semi-circular shell, and a through groove is provided on the top of the semi-circular shell near the side of the semi-cylinder. One end of the plastic film is connected to a magnetic block after passing through the through groove. A fourth electromagnet is installed on one side of the upper end of the through groove, and a third electromagnet is installed on the top of the semi-cylinder near the side of the semi-circular shell. The third electromagnet and the magnetic block are located on the same horizontal plane and their positions correspond to each other.

[0015] Compared with existing technologies, the advantages of this invention are: 1. This invention features a rapidly responsive baffle structure at the chassis ventilation opening, which, in conjunction with an electromagnet and spring, achieves normal fixation and abnormal ejection. When leakage from the circulation pipe causes a short circuit and sparks, the baffle can cover the ventilation opening in a very short time, forming a physical barrier that isolates the air, effectively inhibiting the contact between open flame and external oxygen, reducing the risk of flame spread and propagation. At the same time, it can also prevent dust, moisture, and foreign objects from entering during daily downtime or transportation, improving the overall safety and reliability of the chassis.

[0016] 2. This invention, through the cooperation of a bracket, electromagnet, spring, motor and rotating rod, can actively disconnect the power cord and pop out the bracket when a fire occurs inside the chassis, cutting off the power supply from the source and preventing the fire from spreading along the cable, significantly reducing the risk of secondary combustion; at the same time, the position of the bracket can be flexibly adjusted as needed, which is convenient for cable management and fixation, and the outer rubber pad plays a buffering and protective role during ejection or movement, taking into account both safety protection and daily use convenience.

[0017] 3. The chassis of this invention adopts a reasonable fan arrangement to form a natural convection heat dissipation path with bottom inlet and top outlet. Combined with the water cooling system, it achieves efficient and stable heat conduction and release. The water cooling head is in direct contact with the CPU, and the coolant circulates in the circulation pipe and radiator, fully exchanging heat with the air. This ensures that the heat dissipation effect can still be maintained under high load conditions, avoiding accelerated component aging or safety hazards caused by local overheating, and improving the overall stability of the machine.

[0018] 4. This invention uses a ball screw and an electric telescopic mechanism to drive the humidity sensor to move along the circulation pipe, achieving accurate detection of the leakage location and triggering a response in the early stages of leakage; the sponge sheet can quickly absorb the leaking liquid and, with the help of glue, housing and gear structure, tightly wrap the leak point, effectively isolating the liquid from the motherboard, power supply and other key components, avoiding short circuits and corrosion problems, and significantly reducing the damage caused by the failure of the water cooling system.

[0019] 5. The plastic film of this invention is used in conjunction with a magnetic structure to further form an outer sealed barrier after the sponge sheet is fully covered, locking the absorbed liquid inside and preventing it from dripping and spreading after saturation; at the same time, through the rotating structure of the irregular plate and the folded plate, the sponge sheet can adapt to circulation pipes with different bending shapes, and with the addition of a water storage tank to collect trace amounts of leakage liquid, multiple protections are superimposed, improving the integrity and reliability of the overall emergency response.

[0020] In summary, this invention focuses on chassis fire prevention, water-cooling leakage monitoring and emergency response. Through the coordinated operation of multi-level mechanical, electromagnetic and monitoring structures, it achieves rapid fire suppression, active power cut-off, precise leakage coverage and secondary protection, effectively reducing the risks of short circuits, combustion and corrosion, and significantly improving the safety and stability of host operation while ensuring efficient heat dissipation.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Reference Figures 1 to 10 A water leakage protection device for a computer host using a water-cooled radiator includes a chassis 1. The chassis 1 has ventilation openings at the top, bottom, front, and right ends. Inside the chassis 1, there is a first fan 15 at the top, a second fan 16 at the front, a third fan 17 at the bottom, and a radiator 18 on the right side. The first fan 15, the second fan 16, the third fan 17, and the radiator 18 together form an air duct for cooling the interior of the chassis 1. The working end of the radiator 18 is connected to a circulation pipe 19. The end of the circulation pipe 19 away from the radiator 18 is connected to a water cooling head 20. The water cooling head 20 is detachably installed on the motherboard of the computer host and is in contact with the CPU for cooling the CPU.

[0025] Protective housings 2 are detachably installed on both sides of the top ventilation opening of chassis 1. A baffle 6 is slidably connected inside the protective housing 2. The baffle 6 is made of a material that can be magnetically attracted. Multiple first springs 8 are connected between the baffle 6 and the inner wall of the protective housing 2. Several first electromagnets 7 are fixedly installed inside the protective housing 2 on the side away from the top ventilation opening of chassis 1. In the initial state, the first electromagnets 7 attract the baffle 6 by magnetic force, thereby compressing the first springs 8. After the first electromagnets 7 are de-energized, the magnetic attraction force on the baffle 6 disappears. Under the elastic force of the first springs 8, the baffle 6 pops out from inside the protective housing 2, thereby sealing the top ventilation opening of chassis 1.

[0026] A bracket 5 is provided at the rear of the chassis 1. A second electromagnet 11 is fixedly connected to both ends of the bracket 5 near the chassis 1. The bracket 5 is magnetically connected to the side wall of the chassis 1 through the second electromagnet 11. A through groove is opened in the middle section of the bracket 5. Two rubber sheets 9 are provided inside the through groove. The plug and wires used for powering the computer host pass through the two rubber sheets 9. A rotating rod 4 is installed on the side of the bracket 5 away from the chassis 1. The rotating rod 4 is driven to rotate by a first motor 12 fixedly installed at the end of the bracket 5. A cavity is provided inside both ends of the bracket 5. A second spring 10 is provided inside the cavity. A stop block 43 is connected to the end of the second spring 10 near the chassis 1. The length of the second spring 10 in the normal state is greater than the length of the cavity. Rubber pads 3 are wrapped on both ends of the bracket 5 to prevent the bracket 5 from being damaged when it falls.

[0027] Inside the chassis 1, a horizontally arranged first ball screw 13 is installed. A longitudinally arranged second ball screw 14 is mounted on the moving end of the first ball screw 13 via a support plate. A horizontally arranged first electric telescopic rod 21 is fixedly connected to the moving end of the second ball screw 14. A folding plate 22 is fixedly connected to the telescopic end of the first electric telescopic rod 21. A shaped plate 24 is rotatably mounted above the folding plate 22. The shaped plate 24 is driven by a second motor 25 fixedly mounted at the bottom of the folding plate 22. A humidity sensor 23 is installed above the shaped plate 24. A horizontally arranged second electric telescopic rod 29 is installed on one side of the top of the shaped plate 24. A second arc-shaped housing 36 is fixedly connected to the telescopic end of the second electric telescopic rod 29. A semi-circular housing 30 is rotatably mounted inside the second arc-shaped housing 36. A first arc-shaped housing 35 is installed on the other side of the top of the shaped plate 24. A semi-cylinder 31 is rotatably mounted inside the first arc-shaped housing 35. The semi-circular housing 30 is located on the second... Arc-shaped racks 41 are fixedly connected to the side walls inside the arc-shaped housing 36 and the side walls inside the first arc-shaped housing 35 of the semi-cylinder 31. A gear 42 is meshed with one side of the arc-shaped rack 41. The gear 42 is driven by a third motor 34 fixedly installed on the first arc-shaped housing 35 or the second arc-shaped housing 36. When the third motor 34 is running, it can drive the semi-circular housing 30 and the semi-cylinder 31 to rotate through the meshing action of the gear 42 and the arc-shaped rack 41. A U-shaped sponge sheet 27 is provided between the semi-circular housing 30 and the semi-cylinder 31. The upper two sides of the sponge sheet 27 are respectively snapped with the corresponding semi-circular housing 30 or semi-cylinder 31 by rubber blocks 40. A film bag 28 is glued to the inner walls of the upper two sides of the sponge sheet 27. The two film bags 28 are staggered and filled with glue. The lower side of the film bag 28 is provided with an easy-tear opening, so that the glue inside the film bag 28 can be squeezed out from the lower opening when the film bag 28 is squeezed.

[0028] A plastic film 39 is rolled up inside the semi-circular shell 30. A through groove 38 is provided on the top of the semi-circular shell 30 near the semi-cylinder 31. One end of the plastic film 39 is connected to a magnetic block 32 after passing through the through groove 38. A fourth electromagnet 37 is installed on the upper side of the through groove 38. In the initial state, the magnetic block 32 and the fourth electromagnet 37 are magnetically attracted together. A third electromagnet 33 is installed on the top of the semi-cylinder 31 near the semi-circular shell 30. The third electromagnet 33 and the magnetic block 32 are located on the same horizontal plane and their positions correspond to each other.

[0029] A water storage tank 26 is provided below the sponge sheet 27. The water storage tank 26 is located inside the irregular plate 24 and is movably connected to it.

[0030] In use, the first electromagnet 7 fixes the baffle 6 inside the protective housing 2. When the circulation pipe 19 inside the chassis 1 leaks and comes into contact with electronic components, causing a short circuit and sparks, the first electromagnet 7 is disconnected. Under the action of the first spring 8, the baffle 6 quickly extends, covering the ventilation opening on the chassis 1, forming a physical barrier to prevent the flame from contacting the outside air and preventing the fire from spreading. Furthermore, when the main unit is not in use or needs to be moved, the baffle 6 can also be used to cover the ventilation opening to prevent dust, moisture, or foreign objects from entering the chassis 1, protecting the internal components.

[0031] The bracket 5 can be fixed to the chassis 1 by the second electromagnet 11 on the bracket 5, at which time the second spring 10 is in a compressed state. Then, the power cord is wound around the rotating rod 4, and the plug is inserted into the chassis 1 through the rubber sheet 9. When the chassis 1 catches fire, the first motor 12 is started first to drive the rotating rod 4 to rotate. The power cord wound on the rotating rod 4 will also rotate, thereby driving the plug away from the chassis 1. At the same time, the second electromagnet 11 is disconnected. Under the action of the second spring 10, the bracket 5 will pop out of the chassis 1, preventing the fire source from continuing to spread along the power cord and avoiding further damage from the fire. By using the second electromagnet 11 to directly attach the bracket 5 to the chassis 1, the position of the bracket 5 can be easily adjusted according to different host needs, thus facilitating the quick and easy organization and fixing of power cords or other connecting wires. In addition, the bracket 5 is wrapped with a rubber pad 3 on the outside, which can reduce the damage to the plug or the first motor 12 during ejection.

[0032] Inside the chassis 1, the third fan 17 blows air from the outside in, while the first fan 15, the second fan 16, and the radiator 18 blow air from the inside out. This design draws in cool air from the bottom, while hot air, being less dense, rises naturally and is then expelled through the first fan 15, the second fan 16, and the radiator 18, creating a natural convection path that improves cooling efficiency. The water block 20 is fixed to the CPU on the motherboard and is connected to the radiator 18 via a circulation tube 19. The water block 20 directly contacts the CPU and quickly absorbs heat through its metal base. As the coolant flows through the circulation tube 19 and passes through the water block 20, it absorbs heat and its temperature rises. It then flows through the radiator 18, where it exchanges heat with the air. The heat is dissipated to the outside of the chassis 1 through air convection and radiation, thus completing continuous cooling.

[0033] Inside the chassis 1, the humidity sensor 23 can be moved via the first ball screw 13, the second ball screw 14, and the first electric telescopic rod 21, allowing the humidity sensor 23 to move along the circulation pipe 19. When water leaks at a certain point in the circulation pipe 19, the humidity sensor 23 will detect the increased humidity at that point. At this time, the sponge sheet 27 below the humidity sensor 23 is located in the leaking area. This device triggers a response at the initial stage of leakage, preventing the leakage from spreading to critical components such as the motherboard and power supply, and reducing the risk of short circuits and corrosion. The two ends of the sponge sheet 27 are respectively secured to the semi-circular shell 30 and the semi-cylinder 31 by rubber blocks 40, ensuring that the sponge sheet 27 does not slip during rotation. Both the semi-circular shell 30 and the semi-cylinder 31 are equipped with arc-shaped racks 41, and the semi-circular shell 30 and the second arc-shaped shell 36 are rotatably connected, as are the semi-cylinder 31 and the first arc-shaped shell 35. After the sponge sheet 27 moves to the leaking area, the second electric telescopic rod 29 extends, driving the semi-circular housing 30 towards the semi-cylinder 31 until the semi-circular housing 30 and the semi-cylinder 31 are in contact. When the semi-circular housing 30 and the semi-cylinder 31 are in contact, the mechanical pressure will break the film bag 28, releasing the glue inside. The released glue will bond the two ends of the sponge sheet 27, preventing the sponge sheet 27 from loosening and allowing it to better wrap around the leaking circulation pipe 19. Then, the third motor 34 is started, driving the semi-circular housing 30 and the semi-cylinder 31 to rotate through the arc rack 41 and gear 42. During the rotation of the semi-circular housing 30 and the semi-cylinder 31, the two ends of the sponge sheet 27 will also rotate. Under the action of the glue, the rotating sponge sheet 27 will finally wrap around the leaking area of ​​the circulation pipe 19, effectively preventing the leaked liquid from contacting the motherboard, power supply and other critical components, avoiding secondary damage such as short circuits and corrosion.

[0034] After the sponge sheet 27 is fixed, the fourth electromagnet 37 is disconnected, the third electromagnet 33 is activated to attract the magnetic block 32, and then the second electric telescopic rod 29 is retracted. At this time, the plastic film 39 inside the semi-circular shell 30 will be pulled out. Then the second ball screw 14 is activated to drive the semi-circular shell 30 and the semi-cylinder 31 to move downward. During this process, the plastic film 39 will continue to be pulled out, thus wrapping around the sponge sheet 27. When the semi-circular shell 30 and the semi-cylinder 31 move below the circulation tube 19, the second electric telescopic rod 29 is extended again, so that the semi-circular shell 30 and the semi-cylinder 31 are in contact. At this time, the fourth electromagnet 37 is activated, the third electromagnet 33 is disconnected, so that the magnetic block 32 is attracted to the semi-circular shell 30, and then the second arc-shaped shell 36 is retracted, thus causing the plastic film 39 to completely wrap around the sponge sheet 27. A plastic film 39 wraps around the sponge sheet 27 to form a physical barrier. After the leaked liquid is absorbed by the sponge sheet 27, the plastic film 39 locks the liquid inside the sponge sheet 27, preventing the liquid from dripping out once the sponge sheet 27 is saturated. Furthermore, the irregularly shaped plate 24 and the folded plate 22 are rotatably connected. A second motor 25 drives the irregularly shaped plate 24 to rotate, thereby driving the sponge sheet 27 to rotate, allowing the sponge sheet 27 to adapt to the bending of the circulation pipe 19. A water storage tank 26 is also installed on the irregularly shaped plate 24 to collect trace amounts of leaked liquid, further preventing the leak from spreading.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
