Description

Technical Field

[0001] The present invention relates to the technical field of liquid-cooled computer cases, and particularly to a liquid-cooled computer case with an internal and external double-circulation system. Background Art

[0002] A liquid-cooled computer case is a device that achieves efficient heat dissipation by means of liquid circulation. It is widely used in the field of electronic devices, especially suitable for high-heat-generating computers, servers, and industrial control devices, etc. It mainly consists of a circulation system, a radiator, a control system, and a computer case body. The liquid-cooled computer case has significant advantages. Compared with traditional air cooling, its heat dissipation efficiency is greatly improved, and it can effectively meet the heat dissipation requirements of high-power density devices, such as high-performance gaming computers and data center servers, and can prevent performance degradation and failures caused by overheating.

[0003] When the liquid-cooled computer case is applied as the key main structure of devices such as servers and computers, its cooling principle mainly relies on the coordinated operation of the cooling medium injected inside, heat dissipation fins, and fans to achieve the heat exchange process of the cooling medium. Under normal operating conditions, the cooling medium in the liquid-cooled computer case is usually in a relatively unified space environment without effective partitioning; when various structures in the computer case, such as the motherboard, CPU of the server, and components such as the graphics card and hard disk of the computer, generate heat during operation, since the cooling medium is distributed in the same space, these heats will quickly and without difference be transferred to all the cooling medium. When the internal structure of the computer case operates at a high load for a long time, heat is continuously released and incorporated into the cooling medium, and the temperature of the cooling medium will gradually rise accordingly; and the cooling efficiency of the cooling medium is closely related to its own temperature. As the temperature rises, the temperature difference between it and the heat-generating components gradually decreases. According to the heat transfer principle, the ability of the cooling medium to absorb heat weakens, thereby resulting in a deterioration of the overall cooling effect. For this reason, we propose a liquid-cooled computer case with an internal and external double-circulation system. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a liquid-cooled computer case with an internal and external double-circulation system, which solves the problem that the cooling medium in the existing liquid-cooled computer case is usually in a relatively unified space environment without effective partitioning. When components such as the motherboard, CPU, graphics card, and hard disk of the computer generate heat during operation, since the cooling medium is distributed in the same space, these heats will quickly and without difference be transferred to all the cooling medium. When the internal structure of the computer case operates at a high load for a long time, heat is continuously released and incorporated into the cooling medium, and the temperature of the cooling medium will gradually rise accordingly; and the cooling efficiency of the cooling medium is closely related to its own temperature. As the temperature rises, the temperature difference between it and the heat-generating components gradually decreases.

[0055] Working principle of the present invention: When using a liquid-cooled chassis as the housing, open the cover plate 4, install the motherboard structure composed of accessories such as the motherboard, graphics card, and CPU on the upper layer of the partition 611. After the installation is completed, inject the cooling medium into the lower layer space of the partition 611 through the round holes on the partition 611. After the injection of the cooling medium is completed, fix the guiding pipe 617 in the round hole, and then inject the cooling medium into the upper layer space of the partition 611. After the injection of the cooling medium in the upper layer space is completed, fix the cover plate 4 above the frame 2 again, and fix the water outlet pipe 711 into the installation hole. After the above operations are completed, inject the cooling medium into the second outer water tank 74 through the hole of the installation conduit two 78. After the injection of the cooling medium is completed, fix the conduit two 78 into the hole again;

[0056] After the above entire preparation process is completed, power on the chassis. When the temperature of the cooling medium in the upper layer of the partition 611 reaches 50 °C ± 5 °C, the temperature sensor 63 cooperates with the control panel 5 to control the operation of the first pump 613 and the second pump 616. The first pump 613 is powered on and pumps the cooling medium in the lower layer of the partition 611 into the connector 614 at a speed of 1.5 L / min through its input end. The connector 614 cooperates with the sprayer 612 to pressurize and send the cooling medium pumped by the first pump 613 into the cooling medium in the upper layer of the partition 611. When the next cooling medium pumped by the first pump 613 enters the upper layer cooling medium, the upper layer cooling medium is disturbed by the lower layer cooling medium, generating a flowing effect, and cools down the cover plate 4 above the partition 611 and the motherboard structure composed of accessories such as the motherboard, graphics card, and CPU in the flowing state;

[0057] When the second pump 616 is working, it pumps the upper layer cooling medium to the guiding pipe 617. The guiding pipe 617 cooperates with the spline heat conducting sheet 618 to transfer the heat in the flowing cooling medium to the heat dissipation frame 615. The heat dissipation frame 615 transfers the heat to the outside. At the same time, the heat dissipation fan 6110 is powered on and works under the control of the control panel 5, and blows air to the outside of the heat dissipation frame 615, so that the heat of the heat dissipation frame 615 is dissipated through the grid part under the protective cover 619;

[0058] When the temperature of the upper cooling medium reaches 65°C ± 5°C, the control panel 5 controls the first pump 613 to increase its working power so that the power of the first pump 613 reaches 2.5 L / min. At the same time, when the pumped cooling medium passes through the outlet of the sprayer 612, it pushes the load-bearing plate 625 upward. At this time, the acting force on the load-bearing plate 625 is greater than the adsorption force between the magnet 624 and the adsorption iron ring 622. Under the action of the cooling medium, the load-bearing plate 625 pushes the conical column 626 upward. The conical column 626 moves downward and blocks the outlet of the sprayer 612, reducing the outlet specification of the sprayer 612. Immediately, the spraying speed and pressure of the cooling medium increase to enhance the disturbance effect on the upper cooling medium and improve the fluidity and heat dissipation efficiency of the upper cooling medium;

[0059] When the temperature of the upper cooling medium reaches 75°C ± 5°C, the control panel 5 controls the first solenoid valve 73 to open. The first solenoid valve 73 is powered on and works, and cooperates with the connecting pipe 72 to connect the inside of the chassis and the first external water tank 71. Immediately, the upper cooling medium inside the chassis flows into the first external water tank 71. After the first solenoid valve 73 is opened for 5 minutes, the control panel 5 controls the first solenoid valve 73 to close. At the same time, the control panel 5 controls the second solenoid valve 76 and the third solenoid valve 79 so that the second conduit 78 and the water outlet pipe 711 are respectively connected to the third pump 75. Immediately, under the control of the control panel 5, the third pump 75 pumps the room-temperature cooling medium in the second external water tank 74 into the upper cooling medium of the chassis through the cooperation of the second solenoid valve 76, the third solenoid valve 79, the second conduit 78 and the water outlet pipe 711. When the upper cooling medium is mixed with the cooling medium in the second external water tank 74, the temperature of the upper cooling medium will decrease;

[0060] After the third pump 75 works for 5 minutes, the control panel 5 controls the second solenoid valve 76 and the third solenoid valve 79 so that the first conduit 77 and the water inlet pipe 710 are respectively connected to the third pump 75. The third pump 75 works and pumps the cooling medium in the first external water tank 71 into the second external water tank 74. After the cooling medium in the first external water tank 71 is pumped into the second external water tank 74, the control panel 5 controls the third pump 75, the second solenoid valve 76 and the third solenoid valve 79 to close, so that the replaced cooling medium is stored in the second external water tank 74. At the same time, the second external water tank 74 gradually transfers the heat in the cooling medium through its own heat conduction effect;

[0061] By setting the internal circulation component and the external circulation component, when the liquid-cooled chassis is working, the internal space of the chassis can be divided into upper and lower layers. At the same time, the cooling medium can circulate and convert between the upper and lower layers of the chassis to improve the cooling effect of the liquid-cooled chassis on components such as the motherboard.
