Description

Technical Field

[0001] This invention relates to the field of heat sink technology, specifically to a computer heat sink that achieves rapid cooling. Background Technology

[0002] As computer performance continues to improve, the integration and power consumption of central processing units (CPUs) and graphics processing units (GPUs) are increasing. Under high load, these processors generate a large amount of heat, causing their temperatures to rise rapidly. If this heat cannot be dissipated in time, the processor will trigger frequency throttling protection or even be damaged due to overheating. Currently, among mainstream cooling solutions, air cooling is simple in structure but has limited capacity. Water cooling, which transfers heat to the radiator through coolant circulation, offers superior cooling efficiency compared to air cooling and has become the preferred choice for high-performance computers.

[0003] However, existing water-cooling systems still have the following shortcomings: First, they have a lag in thermal response. The coolant has a long circulation path and high thermal inertia, so it cannot immediately remove heat when the processor experiences a momentary heat spike. Second, they lack active cooling and instantaneous compensation capabilities, and cannot actively inject low-temperature coolant into the circuit for forced cooling when the temperature rises sharply. Third, the heat exchange structure is simple. The coolant flows in a columnar shape in the pipes, with limited contact area with the fins, and the pipe layout is prone to creating local hot spots, affecting the overall heat dissipation efficiency.

[0004] Therefore, a computer heat sink that can respond quickly, has the ability to store and displace cold, and has high heat exchange efficiency is needed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a computer heat sink for achieving rapid cooling, including a chassis, in which a motherboard, a central processing unit, a graphics processing unit, a water-cooled heat sink, a rapid cooling device and a power supply are installed, and the water-cooled heat sink and the rapid cooling device are provided in two sets, each set of the water-cooled heat sink is connected to a set of rapid cooling devices, and the two sets of water-cooled heat sinks respectively dissipate heat from the central processing unit and the graphics processing unit. The water-cooled radiator includes a water pump, the outlet of which is connected to an output water-cooling pipe, the inlet of which is connected to a return water-cooling pipe, and the return water-cooling pipe is equipped with a rapid cooling device. The rapid cooling device includes a cooling fan, a first cooling fin, an annular cavity, a second cooling fin, and a cold storage and displacement assembly. The first cooling fin is arranged in an annular, equidistant configuration. The inner ring of the first cooling fin is connected to the outer ring of the annular cavity. The inner ring of the annular cavity is connected to the outer ring of the second cooling fin, which is also arranged in an annular, equidistant configuration. The inner ring of the second cooling fin is equipped with a cold storage and displacement assembly. The upper end of the annular cavity is connected to one end of a first branch conduit, and the lower end of the annular cavity is connected to one end of a second branch conduit. The other end of the first branch conduit is connected to the outer ring of the second branch conduit, and the other end of the second branch conduit is connected to the outer ring of one end of a return water cooling pipe. Cooling fans are respectively provided at the upper and lower ends of the first cooling fin.

[0006] Furthermore, the cold storage and displacement assembly includes a cylindrical cavity, a servo motor, a screw, a piston plate, a first water-cooled pipe, a second water-cooled pipe, a first pumping water-cooled pipe, and a thermal insulation check valve assembly. A screw is mounted on the central axis of the cylindrical cavity. The top of the screw passes through the cylindrical cavity and is connected to the output end of the servo motor. The servo motor is mounted on the top of the cylindrical cavity. A piston plate is threaded onto the outer ring of the screw, and the piston plate slides against the inner wall of the cylindrical cavity. The top of the cylindrical cavity is connected to one end of the first pumping water-cooled pipe, and the other end of the first pumping water-cooled pipe is connected to the return water-cooled pipe. The bottom of the screw is rotatably connected to the thermal insulation check valve assembly. The return water-cooled pipe passes through the bottom of the cylindrical cavity and is movably connected to the thermal insulation check valve assembly. One end of the first water-cooled pipe is connected to the top of the cylindrical cavity, and the other end of the first water-cooled pipe is connected to the outer ring of the second water-cooled pipe. Both ends of the second water-cooled pipe are connected to the bottom of the cylindrical cavity and the bottom of the annular cavity.

[0007] Furthermore, the heat insulation check valve assembly includes a telescopic elastic element. The lower outer ring of the telescopic elastic element slides with the inner ring of the sliding ring plate. The outer ring of the sliding ring plate slides with the inner wall of the cylindrical cavity. The sliding ring plate has equidistant perforations in an annular shape. The perforations slide with a sliding rod. The lower outer ring of the sliding rod has multiple rectangular grooves equidistantly formed in an annular shape. A first elastic element is sleeved on the outer ring of the sliding rod. The upper and lower ends of the first elastic element abut against the lower end of the sliding ring plate and the bottom surface of the inner wall of the cylindrical cavity, respectively.

[0008] Furthermore, an outer air guide shroud is provided between the two fans, and the inner ring of the outer air guide shroud is connected to the outer ring of the first heat dissipation fins arranged in an annular shape at equal intervals.

[0009] Furthermore, a first check valve is installed on the first water cooling pipe, and a second check valve is installed at the position where the second water cooling pipe communicates with the bottom of the annular cavity. Both the first check valve and the second check valve are thermal bridge blocking one-way valves.

[0010] Furthermore, the first branch conduit, the second branch conduit, the first water-cooling pipe, and the second water-cooling pipe are all arranged in a ring at equal intervals, while the second water-cooling pipe and the second branch conduit are arranged in an alternating pattern.

[0011] Furthermore, the telescopic elastic element includes a slidingly fitted inner piston rod and an outer piston ring. A through hole is opened at the bottom of the outer piston ring. A second elastic element is fitted on the outer piston ring. One end of the second elastic element abuts against the lower end of the outer piston ring, and the other end of the second elastic element abuts against the upper end of the inner piston rod. The bottom of the outer piston ring is in movable contact with the port of the return water cooling pipe.

[0012] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) By setting up a cold storage and replacement component, low-temperature coolant is pre-stored in the cylindrical cavity. When the central processing unit or graphics processor experiences a sudden temperature rise due to high load operation, the servo motor drives the piston plate to move, forcibly pressing the low-temperature coolant into the annular cavity (64) through the first water cooling pipe (when moving upward) or through the second water cooling pipe, directly mixing with the high-temperature coolant in the annular cavity to cool down. This can significantly reduce the circuit temperature in a very short time, preventing the processor from downclocking or being damaged due to thermal spikes, and significantly improving the heat dissipation effect under high load scenarios. (2) By placing the annular cavity between the first and second heat dissipation fins arranged at equal intervals in an annular shape, and forcing the coolant to flow into an annular liquid layer after entering the annular cavity, the coolant, which was originally concentrated in the pipe, spreads evenly in the annular cavity along the circumference, forming a thin-walled annular liquid flow, thereby significantly increasing the contact area between the coolant and the first and second heat dissipation fins. Forced air cooling is achieved by using two cooling fans to create a through-flow, allowing the heat of the annular liquid layer to be quickly transferred to the airflow and carried away through the fins. Simultaneously, the first branch pipe, second branch pipe, first water-cooling pipe, and second water-cooling pipe are arranged in an annular, equidistant, and staggered pattern, ensuring uniform distribution and efficient heat exchange of the annular coolant within the annular cavity. The overall structure is compact, further improving heat exchange efficiency. Attached Figure Description

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0017] like Figures 1 to 7As shown, the present invention provides a computer heat sink for rapid cooling, comprising a chassis 1, inside which are installed a motherboard 2, a central processing unit 3, a graphics processing unit 4, a water-cooled heat sink 5, a rapid cooling device 6, and a power supply. Two sets of water-cooled heat sinks 5 and rapid cooling devices 6 are provided, each set of water-cooled heat sinks 5 connected to one set of rapid cooling devices 6. The two sets of water-cooled heat sinks 5 independently cool the central processing unit 3 and the graphics processing unit 4 without interference, thereby meeting the heat dissipation requirements of a high-power dual-core system.

[0018] The water-cooled radiator 5 includes a water pump 51, with an output water-cooling pipe 52 connected to the outlet of the water pump 51 and a return water-cooling pipe 53 connected to the inlet of the water pump 51. A rapid cooling device 6 is installed on the return water-cooling pipe 53. This circuit allows the coolant to circulate continuously under the drive of the water pump 51, constantly carrying away the heat generated by the processor.

[0019] The rapid cooling device 6 includes a cooling fan 62, first heat dissipation fins 63, an annular cavity 64, second heat dissipation fins 65, and a cold storage and displacement assembly 66. The first heat dissipation fins 63 are arranged in annular equidistant configurations, with their inner ring connected to the outer ring of the annular cavity 64. The inner ring of the annular cavity 64 is connected to the outer ring of the second heat dissipation fins 65, which are also arranged in annular equidistant configurations. The cold storage and displacement assembly 66 is located within the inner ring of the second heat dissipation fins 65. The upper end of the annular cavity 64 is connected to one end of a first branch conduit 67, and the lower end of the annular cavity 64 is connected to one end of a second branch conduit 68. The other end of the first branch conduit 67 is connected to the outer ring of the second branch conduit 68, and the other end of the second branch conduit 68 is connected to the outer ring of one end of a return water cooling pipe 53. Cooling fans 62 are respectively located at the upper and lower ends of the first heat dissipation fins 63, and an outer air guide shroud 61 is located between the two fans. The inner ring of the outer air guide shroud 61 is connected to the outer ring of the first heat dissipation fins 63. This structure forces the coolant flowing through the annular cavity 64 to spread into a thin, circular layer, significantly increasing the contact area with the first heat dissipation fins 63 and the second heat dissipation fins 65. Combined with the forced convection formed by the upper and lower fans, this significantly improves the air-cooled heat exchange efficiency.

[0020] The cold storage and displacement assembly 66 includes a cylindrical cavity 667, a servo motor 661, a screw 662, a piston plate 663, a first water-cooling pipe 664, a second water-cooling pipe 665, a first extraction water-cooling pipe 666, and a thermal insulation check assembly 7. A screw 662 is mounted on the central axis of the cylindrical cavity 667. The top of the screw 662 passes through the cylindrical cavity 667 and is connected to the output end of the servo motor 661, which is mounted on the top of the cylindrical cavity 667. The piston plate 663 is threaded onto the outer ring of the screw 662 and slides against the inner wall of the cylindrical cavity 667. The top of the cylindrical cavity 667 is connected to one end of the first extraction water-cooling pipe 666, and the other end of the first extraction water-cooling pipe 666 is connected to the return water-cooling pipe 53. The bottom of the screw 662 is rotatably connected to the thermal insulation check assembly 7. The return water-cooling pipe 53 passes through the bottom of the cylindrical cavity 667 and is movably connected to the thermal insulation check assembly 7. One end of the first water-cooling pipe 664 is connected to the top of the cylindrical cavity 667, and the other end of the first water-cooling pipe 664 is connected to the outer ring of the second water-cooling pipe 665. The two ends of the second water-cooling pipe 665 are respectively connected to the bottom of the cylindrical cavity 667 and the bottom of the annular cavity 64.

[0021] The heat-insulating check valve assembly 7 includes a telescopic elastic element 71, a sliding ring plate 72, a slide rod 73, and a first elastic element 74. The lower outer ring of the telescopic elastic element 71 slides against the inner ring of the sliding ring plate 72, and the outer ring of the sliding ring plate 72 slides against the inner wall of the cylindrical cavity 667. The sliding ring plate 72 has annularly spaced perforations, which slide against the slide rod 73. The lower outer ring of the slide rod 73 has multiple annularly spaced rectangular grooves, and the first elastic element 74 is fitted onto the outer ring of the slide rod 73. The upper and lower ends of the first elastic element 74 abut against the lower end of the sliding ring plate 72 and the inner bottom surface of the cylindrical cavity 667, respectively. The telescopic elastic element 71 includes a slidingly fitted inner piston rod 711 and an outer piston ring 712. A through hole is formed at the bottom of the outer piston ring 712. A second elastic element 713 is fitted onto the outer piston ring 712. One end of the second elastic element 713 abuts against the lower end of the outer piston ring 712, and the other end abuts against the upper end of the inner piston rod 711. The bottom of the outer piston ring 712 movably abuts against the port of the return water cooling pipe 53.

[0022] To block heat transfer between the high-temperature and low-temperature coolant within the cylindrical cavity 667, the sliding ring plate 72, inner piston column 711, outer piston ring 712, and slide rod 73 in the thermal insulation check valve assembly 7 are all made of thermally insulating materials with low thermal conductivity (such as polyetheretherketone, ceramic, or reinforced nylon), or have a thermally insulating coating applied to the surface of the metal parts. Simultaneously, the sliding mating surfaces of the sliding ring plate 72 and slide rod 73, and the sliding mating surfaces of the inner piston column 711 and outer piston ring 712, are fitted with small clearances and filled with thermally insulating grease to reduce heat transfer through the contact surfaces. Through this thermal insulation design, when the upper end of the cylindrical cavity 667 stores low-temperature coolant and the lower end stores high-temperature coolant, the linkage mechanism consisting of the sliding ring plate 72, inner piston column 711, outer piston ring 712, and slide rod 73 itself becomes a thermal bridge blocking layer, effectively preventing heat transfer from the high-temperature side to the low-temperature side. This maintains the cooling effect of the low-temperature coolant for a long time, ensuring sufficient cooling capacity can be output during sudden high-temperature events.

[0023] Furthermore, a first check valve 668 is installed on the first water-cooling pipe 666, and a second check valve 669 is installed at the connection point between the second water-cooling pipe 665 and the bottom of the annular cavity 64. Both the first check valve 668 and the second check valve 669 are thermal bridge blocking one-way valves, preventing coolant backflow and blocking heat transfer along the pipe wall. The first branch pipe 67, the second branch pipe 68, the first water-cooling pipe 664, and the second water-cooling pipe 665 are all arranged in annular equidistant configurations, while the second water-cooling pipe 665 and the second branch pipe 68 are arranged in an alternating configuration to ensure uniform coolant flow within the annular cavity 64 and eliminate localized hot spots. Through the synergistic effect of the above structures, this invention can instantly inject low-temperature coolant when the processor temperature rises sharply, achieving rapid cooling, effectively suppressing thermal spikes, and ensuring the stable operation of the high-performance computer.

[0024] The working principle and usage process of this invention: After the computer is started, the water pump 51 draws the coolant from the inlet end of the return water cooling pipe 53, and presses it into the output water cooling pipe 52 through the outlet end. The coolant flows through the water cooling head corresponding to the central processing unit 3 or the graphics processor 4 and absorbs heat to become high-temperature coolant. The high-temperature coolant enters the rapid cooling device 6 through the return water cooling pipe 53.

[0025] Under normal operating conditions, the high-temperature coolant in the rapid cooling device 6 flows into the annular cavity 64 through the return water cooling pipe 53. The airflow passes through the gap between the first heat dissipation fins 63 and the second heat dissipation fins 65 via the cooling fan 62, carrying away the heat of the high-temperature coolant in the annular cavity 64 and cooling it down. The cooled coolant then enters the first branch pipe 67 and the return water cooling pipe 53, and from the return water cooling pipe 53 enters the water pump 51 to complete the normal heat dissipation.

[0026] When the CPU 3 or GPU 4 experiences a sudden temperature rise due to running a high-load program, the system triggers the cold storage and displacement assembly 66. The servo motor 661 drives the screw 662 to rotate, and the piston plate 663 moves upward along the inner wall of the cylindrical cavity 667. As the piston plate 663 moves upward, its upper volume decreases, forcibly pushing the low-temperature coolant at the upper end of the cylindrical cavity 667 out through the first water-cooling pipe 664 and into the second water-cooling pipe 665. From the second water-cooling pipe 665, the coolant enters the annular cavity 64 and merges with the high-temperature coolant inside the annular cavity 64, thus rapidly cooling down. At this time, the first check valve 668 on the first water-cooling pipe 666 is closed to prevent liquid from being discharged from the pipe.

[0027] During this process, when the piston plate 663 moves upward, the volume of the space at the lower end increases, generating negative pressure. Under the action of negative pressure, the outer piston ring 712 moves upward and disengages from the port of the return water cooling pipe 53, compressing the second elastic element 713. The outer piston ring 712 disengages from the inner ring of the sliding ring plate 72, opening the liquid channel. The lower end of the cylindrical cavity 667 draws in an equal amount of high-temperature coolant through the return water cooling pipe 53 connected at the bottom for air-cooled storage.

[0028] When the CPU 3 or GPU 4 experiences a sudden temperature rise due to running a high-load program, the system triggers the cold storage and displacement assembly 66 again. The servo motor 661 drives the screw 662 to rotate in the opposite direction, causing the piston plate 663 to move downward. As the piston plate 663 moves downward, its lower end volume decreases, and the pressure increases. This pressure acts on the sliding ring plate 72, pushing it downward along the slide rod 73, compressing the first elastic element 74, exposing the rectangular groove on the lower outer ring of the slide rod 73, opening the liquid channel. The coolant stored at the lower end of the cylindrical cavity 667, which has already been cooled by air cooling, flows into the second water-cooling pipe 665 through the rectangular groove, and then enters the annular cavity 64 from the second water-cooling pipe 665 to interact with the high temperature inside the annular cavity 64. The coolant flows together, rapidly merging and cooling down. Simultaneously, the piston plate 663 moves downwards, increasing the volume of its upper space and creating negative pressure. This opens the first check valve 668 on the first suction cooling pipe 666. This first check valve 668 is a thermal bridge blocking one-way valve, allowing only liquid to flow from the return cooling pipe 53 into the upper part of the cylindrical cavity 667. An equal amount of high-temperature coolant is drawn from the return cooling pipe 53 through the first suction cooling pipe 666, replenishing the upper part of the cylindrical cavity 667, thus completing the water replenishment. In this way, the downward movement of the piston plate 663 achieves a complete replacement process: the lower end discharges low-temperature coolant for rapid merging and cooling, while the upper end draws in high-temperature coolant for storage and later use.
