Description

Technical Field

[0001] The utility model relates to the field of computer liquid cooling, in particular to a computer case liquid cooling circulation structure. Background Art

[0002] Desktop computers are a common tool in our lives today. When using a computer, especially when the CPU is running at high load, it will generate a lot of heat. If the heat is not dissipated in time, it will easily cause CPU damage or even crash. Common heat dissipation systems include air cooling and liquid cooling.

[0003] Air cooling uses fans to cause high-speed air flow to take away heat from computer components such as the CPU and graphics card. The heat dissipation effect is poor. For industries such as gaming, video editing, scientific computing, 3D modeling, etc. that need to process large amounts of data and perform complex calculations, air cooling can no longer meet the needs. These industries usually use liquid cooling.

[0004] Existing liquid cooling technology mainly utilizes liquid with high specific heat (such as water), which is stored in a liquid cooling box. A simple pressure device is used to make the liquid flow in the laid pipes. The pipes filled with liquid are in contact with the CPU, graphics card and other components. The heat in the CPU, graphics card and other components is introduced into the pipes through heat conduction, and the heat is taken away by the liquid in the pipes. The liquid then flows back to the liquid cooling box, thereby achieving a circulating cooling effect.

[0005] Although liquid cooling is better than air cooling, the liquid in the liquid pipe does not directly contact the CPU, memory, graphics card chip and other components. The liquid is in indirect contact with the heat-generating parts, resulting in limited heat being removed. After working for a long time, the liquid is prone to heat up, thus affecting the heat dissipation effect.

[0006] To this end, a computer case liquid cooling circulation structure is provided. Utility Model Content

[0028] See also Figures 1 to 7 , the utility model provides a technical solution:

[0029] A computer case liquid cooling circulation structure includes a water tank 1, a frame 16 is fixedly connected to the right side of the water tank 1, a fluorinated liquid is contained in the water tank 1, a motor 3 is fixedly connected to the outer side of the water tank 1 near the lower end, a volute 31 is fixedly connected to the front bottom of the water tank 1, a first impeller 32 is arranged inside the volute 31, a rotating shaft of the first impeller 32 passes through the volute 31 and the water tank 1 and is fixedly connected to the output shaft of the motor 3, and the rotating shaft of the first impeller 32 is rotatably connected to the volute 31 and the water tank 1 through a sealed bearing;

[0030] Thirty heat sinks 15 are evenly and fixedly connected in the middle of the front side of the water tank 1, a liquid outlet pipe 33 is connected to the upper side of the annular outer surface of the volute 31, a heat dissipation pipe 34 is plugged into the heat sink 15, the liquid outlet of the liquid outlet pipe 33 is connected to the liquid inlet at the lower end of the heat dissipation pipe 34, the upper end of the heat dissipation pipe 34 is connected to the transfer box 4, the upper side of the annular outer surface of the transfer box 4 is connected to the guide pipe 42, the liquid outlet of the guide pipe 42 penetrates into the water tank 1 and is connected to a branch pipe 43 of a U-shaped structure, and the branch pipe 43 is evenly distributed on the nozzle;

[0031] The upper end of the water tank 1 is provided with a cover plate 11, and a sealing strip 13 is fixedly connected to the lower end surface of the cover plate 11 corresponding to the upper end surface of the water tank 1. A groove matching the sealing strip 13 is provided on the upper end surface of the water tank 1. A screw hole penetrating to the bottom of the groove is provided on the upper end surface of the cover plate 11, and a screw is connected to the inner thread of the screw hole. A liquid filling port 12 is provided on the upper surface of the cover plate 11 near the center position;

[0032] A partition plate 14 is fixedly connected between the frame 16 and the volute 31 inside the water tank 1 , and five leakage holes are formed on the upper end surface of the partition plate 14 .

[0033] By adopting the above technical solution, the water tank 1 is installed inside the computer case, and the CPU, motherboard, graphics card and other components are installed on the rack 16, and then the coolant is poured in. The coolant is a fluorinated liquid, which is a colorless, odorless, non-flammable, insulating liquid that can be used for cooling electronic equipment. The coolant is submerged in the CPU, motherboard, graphics card and other components, and then the cover plate 11 is covered, and the screws are screwed into the screw holes on the cover plate 11 to complete the sealing of the water tank 1. The upper end surface of the cover plate 11 is also provided with a data line connector installation port, and the data line connectors of the motherboard, graphics card and other components are installed in the data line connector installation port, and sealed with a sealant, and the computer data cable is connected to the data line connector installation port on the cover plate 11. The computer can be used normally by connecting the data line connector. During the use of the computer, the CPU, motherboard, graphics card and other components will gradually generate heat, and the coolant is in direct contact with the CPU, motherboard, graphics card and other components, so that the heat can be fully absorbed into the coolant, thereby improving the heat dissipation effect. When the computer is running at a high load, the heat generated by the CPU, motherboard, graphics card and other components increases. At this time, the motor 3 can be started to drive the first impeller 32 to rotate, so that the coolant in the water tank 1 is sucked into the volute 31. The coolant entering the volute 31 enters the liquid outlet pipe 33 under the action of centrifugal force, and then enters the heat dissipation pipe 34 coiled inside the heat sink 15. The coolant is then transferred to the heat dissipation pipe 34 through the transfer The cooling liquid sprayed on the CPU, motherboard, graphics card and other components flows into the bottom of the water tank 1 through the leakage hole on the partition 14, and then enters the volute 31 again, and then is transported to the branch pipe 43 and sprayed on the CPU, motherboard, graphics card and other components through the nozzle, so as to form a liquid cooling cycle, improve the fluidity of the cooling liquid, improve the effect of the cooling liquid absorbing heat, and further improve the heat dissipation effect of the CPU, motherboard, graphics card and other components. The setting of the partition 14 can make the cooling liquid sprayed on the CPU, motherboard, graphics card and other components It flows back to the bottom of the water tank 1 through the leak hole at a slower speed, ensuring the fluidity of the coolant while extending the contact time between the coolant and the CPU, motherboard, graphics card and other components, so as to fully absorb the heat emitted by the CPU, motherboard, graphics card and other components and improve the heat dissipation effect. As the coolant continues to absorb heat, the temperature of the coolant itself will increase. When the coolant passes through the heat pipe 34, the heat in the coolant will be conducted to the heat sink 15, thereby reducing the temperature of the coolant, so that the temperature of the coolant when entering the water tank 1 is always maintained below 25 degrees Celsius, so as to continuously absorb the heat generated by the CPU, motherboard, graphics card and other components to ensure the normal operation of the CPU, motherboard, graphics card and other components.

[0034] like Figure 3 , Figure 4 , Figure 5 , Figure 7As shown: a trumpet-shaped cover shell 5 is fixedly inserted at a position below the upper branch pipe 43 near the front side of the interior of the water tank 1, a fixing frame 52 is fixedly connected to the interior of the cover shell 5, a fixed shaft 53 is rotatably inserted at the center of the fixing frame 52, a fan blade 51 is fixedly connected to the rear end of the fixed shaft 53, a front end of the fixed shaft 53 penetrates into the interior of the transfer box 4 and is fixedly connected to the second impeller 41, a front end of the cover shell 5 is connected to a return pipe 54, and a liquid outlet of the return pipe 54 penetrates through the heat sink 15 to the interior of the water tank 1.

[0035] By adopting the above technical solution, since the boiling point of the fluorinated liquid is between 50 and 60 degrees Celsius, and the temperature of the CPU, motherboard, graphics card and other components will exceed 60 degrees Celsius when running under high load, the fluorinated liquid will boil and evaporate into a gaseous state. In this process, a large amount of heat emitted by the CPU, motherboard, graphics card and other components can be taken away. When the coolant in the heat dissipation pipe 34 enters the transfer box 4, it will continuously impact the second impeller 41, thereby driving the second impeller 41 to rotate, and then driving the fan blades 51 to rotate. The rotation of the fan blades 51 generates suction to suck the gaseous coolant into the cover 5, and the gaseous coolant enters the return pipe 54. Since the liquid outlet at the lower end of the return pipe 54 penetrates into the water tank 1, and The position close to the volute 31 allows the suction generated by the first impeller 32 to suck the gaseous coolant into the bottom of the water tank 1, and the return pipe 54 is coiled inside the heat sink 15, so that when the gaseous coolant passes through the heat sink 15, the heat in the gaseous coolant can be conducted to the heat sink 15, thereby condensing the gaseous coolant into liquid coolant, so that the coolant can be reused. The cover plate 11 is sealed and connected to the water tank 1 with a sealing strip 13 to prevent the gaseous coolant from volatilizing, reduce the consumption of the coolant, and save costs. The inner thread of the liquid filling port 12 is connected with a sealing plug. When coolant needs to be added, the sealing plug can be unscrewed and coolant can be added through the liquid filling port 12, which facilitates the addition of coolant.

[0036] like Figure 5 As shown: four pillars are fixedly connected to the front side of the water tank 1 near the four corners, and a protective plate 2 is fixedly connected to the front end of the pillar by bolts. A through hole 21 is opened at the front side of the protective plate 2 corresponding to the heat sink 15, and a heat dissipation fan 22 is installed in the through hole 21.

[0037] By adopting the above technical solution, by installing a cooling fan 22 on the protective plate 2, the heat on the heat sink 15 is extracted out of the chassis through the cooling fan 22, so that the heat sink 15 always maintains a low temperature, thereby being able to continuously absorb the heat of the coolant inside the heat pipe 34 and the heat in the gaseous coolant in the return pipe 54, so as to ensure that the temperature of the coolant is always maintained below 25 degrees Celsius, thereby ensuring the ability to continuously dissipate heat for components such as the CPU, motherboard, and graphics card, and ensuring the normal operation of the computer.

[0038] Working principle: Pour the coolant directly into the water tank 1 until the CPU, motherboard, graphics card and other components on the rack 16 are submerged. When the computer is running at high load, the heat generated by the CPU, motherboard, graphics card and other components increases. At this time, the motor 3 can be started to drive the first impeller 32 to rotate, so that the coolant in the water tank 1 is sucked into the volute 31. The coolant entering the volute 31 enters the liquid outlet pipe 33 under the action of centrifugal force, and then enters the heat dissipation pipe 34 coiled inside the heat sink 15. The coolant then passes through the transfer box 4 and enters the guide pipe 42. Finally, it enters the U-shaped branch pipe 43 through the guide pipe 42, and is sprayed on the CPU, motherboard, graphics card and other components through the nozzle on the branch pipe 43. The coolant sprayed on the CPU, motherboard, graphics card and other components flows into the bottom of the water tank 1 through the leakage hole on the partition 14, and then enters the volute 31 again, and then is transported to the branch pipe 43 and sprayed on the CPU, motherboard, graphics card and other components through the nozzle, so as to form a liquid cooling cycle, improve the fluidity of the coolant, improve the effect of the coolant absorbing heat, and further improve the heat dissipation effect of the CPU, motherboard, graphics card and other components.
