Description

Technical Field

[0001] This invention relates to the field of heat sink technology, and more specifically, to an integrated liquid cooling assembly and method for server fasteners with integrated heat sink fins. Background Technology

[0002] Server fastener integrated liquid cooling is an innovative heat dissipation solution that integrates liquid cooling pipes or structures directly into critical fasteners inside the server. This design conducts heat through microchannels within the fasteners, achieving more efficient and compact heat dissipation, making it particularly suitable for high-density data centers and high-performance computing scenarios. It not only improves cooling efficiency and reduces energy consumption but also simplifies the internal layout of the server, providing reliable assurance for stable operation under high loads.

[0003] Patent application number CN202421057504.2 discloses a server-grade liquid cooling test verification device, including a test shell, a liquid cooling test circulation component, a controller, a power distribution control module, a data acquisition module, and a power supply module. The test shell is set in a liquid cooling cabinet. The liquid cooling test circulation component is set on the upper side of the inside of the test shell. The power supply module, controller, power distribution control module, and data acquisition module are set on the lower side of the inside of the test shell. The power supply module is connected to the power distribution control module for power supply. The liquid cooling circulation test component is connected to the data acquisition module and the controller.

[0004] However, the existing equipment's cooling system is usually loosely composed of independent liquid pumps, electronically controlled regulating valves, and fans, resulting in a complex structure that occupies a large amount of internal server space. The liquid cooling circuit often uses a fixed flow rate or relies on external electrical signals for regulation, lacking a dynamic turbulence mechanism that adapts to the liquid flow velocity. This leads to a stable flow field inside the cold plate and stagnation of the thermal boundary layer, limiting further improvement in heat exchange efficiency. At the same time, liquid cooling and air cooling modules often work independently, failing to achieve synergistic utilization of kinetic energy and organic complementarity of heat dissipation efficiency. Overall energy efficiency and space utilization need to be improved.

[0005] In view of this, we propose an integrated liquid cooling component for server fasteners with integrated heat dissipation fins and a method thereof. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated liquid cooling component and method for server fasteners with integrated heat dissipation fins. By periodically moving the liquid guide plate up and down and generating airflow through the rotation of the fan blades, a composite cooling mechanism is formed, which is mainly liquid cooling, enhanced by dynamic turbulence, and supplemented by air cooling, thus improving the peak heat dissipation capacity of the cooling plate in a limited space and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An integrated liquid cooling assembly for server fasteners with integrated heat dissipation fins includes a cooling system, the cooling system including a driver and a main cooling assembly;

[0009] The driver includes a liquid inlet pipe, a propeller rotating inside the liquid inlet pipe, a toggle assembly positioned above the propeller, a blower chamber positioned at the top of the toggle assembly, and fan blades rotating inside the blower chamber. The end of the central shaft on the bottom surface of the fan blades is snapped and fixed to the propeller. In this configuration, after the refrigerant passes through the liquid inlet pipe, it drives the propeller to rotate, which in turn drives the fan blades to rotate and generate airflow in the blower chamber.

[0010] The actuation assembly includes a cam that is snapped and fixed to the outer wall of the central shaft on the bottom surface of the fan blade, a slide rod whose end abuts against the cam, a spring sleeved on the outside of the slide rod, and a lever that moves with the slide rod. In this configuration, after the cam rotates, it works with the spring to drive the slide rod and the lever to move back and forth laterally.

[0011] The main cooling component includes a cooling plate with two layers of channels inside: the upper layer is a ventilation channel for airflow and the lower layer is a liquid channel for refrigerant flow.

[0012] The main cooling assembly also includes several first fins distributed in the liquid passage, several second fins distributed in the liquid passage and ventilation passage, and a liquid guide plate that slides at the liquid inlet of the liquid passage. The bottom surface of the liquid guide plate is provided with two grooves. In this configuration, when the lever moves back and forth horizontally, the end of the lever moves along the groove, driving the liquid guide plate to move up and down, thereby adjusting the inflow section of the coolant.

[0013] In the technical solution of the present invention, the cooling system further includes a pipe mounting head, a first auxiliary cooling component and a second auxiliary cooling component disposed outside the main cooling component, a liquid-passing pipe connected between the pipe mounting head, the driver, the main cooling component, the first auxiliary cooling component and the second auxiliary cooling component, a fastening plate welded to the outer wall of the main cooling component, the first auxiliary cooling component and the second auxiliary cooling component, and two heat-conducting copper pipes snapped and fixed to the top surface of the second auxiliary cooling component.

[0014] The cooling system is modularized and functionally partitioned. The main cooling component targets the core heat source, while the first and second auxiliary cooling components extend the heat dissipation coverage. Combined with the structural reinforcement of the fastening plate and the auxiliary heat dissipation of the heat-conducting copper pipes, it forms an efficient, complete, and structurally stable integrated heat dissipation module.

[0015] In the technical solution of the present invention, the driver further includes a liquid passage chamber, the top surface of which is welded with a liquid inlet that communicates with the liquid inlet end of the tube mounting head, the liquid passage pipe is snapped and fixed inside the round hole on the top surface of the liquid passage chamber, and the outer wall of the liquid passage pipe is provided with a liquid outlet for snapping and fixing the liquid passage pipe.

[0016] In the technical solution of the present invention, the actuating group further includes a sealing chamber that is snapped and fixed at the top opening of the liquid inlet pipe and a cover plate that is fixedly connected to the top surface of the sealing chamber by screws. The cam is rotatably connected to the inner bottom surface of the sealing chamber, and the slide rod is slidably connected to the circular protrusion on the outer wall of the sealing chamber and its end extends to the outside of the sealing chamber.

[0017] In the technical solution of the present invention, the outer wall of the slide rod is integrally formed with a circular baffle, the two ends of the spring abut against the inner wall of the circular protrusion of the outer wall of the sealing chamber and the circular baffle of the outer wall of the slide rod, the elastic force provided by the spring pushes the slide rod to move in the direction of the cam, and the transverse cross section of the lever is T-shaped and one end is fixedly engaged with the slide rod.

[0018] In the technical solution of the present invention, the blower chamber is snapped and fixed on the top surface of the sealed chamber, a filter screen is snapped into the round hole opened above the fan blade on the top surface of the blower chamber, and a ventilation chamber is snapped and fixed on the outside of the air outlet of the blower chamber.

[0019] The core of the above setup is that the actuator converts the kinetic energy of the fluid into mechanical reciprocating motion through the cam and spring mechanism and drives the fan blades to generate cooling airflow, thus realizing a multi-functional, highly integrated self-driven operation.

[0020] In the technical solution of the present invention, liquid inlet and liquid outlet are respectively provided on the outer walls of the left and right sides of the cooling plate and are connected to the liquid passage groove. Liquid passage pipes are fixedly connected to the inner side of the liquid inlet and liquid outlet. The outer side of the air inlet of the ventilation groove is fixedly connected to the end opening of the ventilation chamber. A filter screen is fixedly connected to the outer side of the air outlet of the ventilation groove.

[0021] In the technical solution of the present invention, the main cooling assembly further includes a heat-conducting plate fixedly connected to the bottom surface of the cooling plate by screws. The first fin is integrally formed with the heat-conducting plate, the second fin is welded and fixed to the cooling plate, and the longitudinal section of the liquid guide plate is bent. When the liquid guide plate is in the lowest position, the horizontal height of its end is higher than the maximum height when the refrigerant passes through.

[0022] The above configuration achieves composite heat dissipation and intelligent adjustment of the main cooling component. Through the physical integration and synergy of liquid cooling and air cooling, combined with the periodic dynamic turbulence of the liquid guide plate, the heat dissipation efficiency and thermal balance in a compact space are significantly improved.

[0023] In the technical solution of the present invention, the bottom of the cooling system is fixedly connected to a base plate by screws, the top of the base plate is snapped and fixedly connected to a top plate, and a computing power card is also snapped and fixed between the base plate and the cooling system. The inside of the base plate is fixedly connected to a liquid supply system that is connected to an external refrigerant circulation system by screws. Two pipes for refrigerant circulation in the liquid supply system are respectively fixedly connected to the inlet and outlet ends in the pipe body mounting head by sealing bolts.

[0024] The above setup constitutes the basic support and liquid supply framework for the server liquid cooling functional module. Through the cooperation of the base plate, top plate and liquid supply system, it provides a stable and reliable installation platform and liquid cooling circulation inlet for the computing card and integrated cooling system.

[0025] On the other hand, the present invention also provides a method for an integrated liquid cooling assembly for server fasteners with integrated heat dissipation fins, comprising the following steps:

[0026] S1. First, install and fix the computing card to the designated position inside the base plate, and fix the fastening plate of the cooling system to the inside of the base plate with screws, ensuring that the bottom surfaces of the main cooling component, the first auxiliary cooling component, and the second auxiliary cooling component are in close contact with the key heat-generating chip positions on the computing card; then complete the installation of the liquid supply system, and connect the circulation pipe of the liquid supply system to the inlet and outlet ends of the pipe body mounting head with sealing bolts; finally, install the top plate on the top of the base plate to complete the assembly of a single liquid cooling functional component;

[0027] S2. Subsequently, several sets of assembled liquid cooling functional components are inserted side by side into the corresponding slots of the server chassis, and the main pipe of the external refrigerant circulation system is connected in parallel with the liquid supply system in each component to complete the integrated installation of the entire liquid cooling system in the server.

[0028] S3. Then, the external refrigerant circulation system is started, and the refrigerant circulates in the cooling system. The refrigerant flows from the liquid inlet into the liquid pipe, drives the propeller to rotate by fluid kinetic energy, and then flows into the liquid pipe through the liquid outlet, and finally enters the main cooling component.

[0029] S4. When the propeller rotates, it drives the cam above to rotate synchronously through its central shaft. During the rotation, the cam periodically pushes against the slide rod, and combined with the reset action of the spring, the slide rod drives the lever to perform horizontal reciprocating motion. The end of the lever is embedded in the groove on the bottom surface of the liquid guide plate, thereby converting the horizontal motion into the vertical motion of the liquid guide plate, thus dynamically adjusting the opening of the liquid inlet of the liquid channel. This periodic change in opening disturbs the flow field of the coolant flowing through the liquid channel, thereby destroying the stagnant heat boundary layer on the surface of the first fin, thereby improving the instantaneous heat exchange efficiency.

[0030] S5. At the same time, the propeller drives the fan blades to rotate synchronously in the blower chamber through the central shaft. The airflow generated is introduced into the ventilation slots of the cooling plate through the ventilation chamber, and forced convection cooling is performed on the second fins distributed in the ventilation slots. This achieves auxiliary air cooling of the cooling plate and further improves the overall heat dissipation performance through synergy with liquid cooling.

[0031] S6. After carrying heat, the coolant flowing through the main cooling component enters the first and second auxiliary cooling components in sequence through the outlet head and the liquid flow pipe, expanding the cooling of the heat-generating area on the computing card; the heat-conducting copper pipe further directs the locally accumulated heat to an area with a larger heat dissipation area, thereby ensuring that the heat is quickly dissipated.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. The integrated liquid cooling component and method for server fasteners with integrated heat dissipation fins integrates the propeller, cam, and fan blades in series within the driver via the same central axis. Through mechanical linkage between the lever and the liquid guide plate, the kinetic energy of the single refrigerant flow is simultaneously converted into automatic regulation of refrigerant flow and forced air cooling. This eliminates traditional external components such as independent motors, electrically controlled valves, and fans, greatly simplifying the system configuration and saving valuable space inside the server. In addition, the mechanical linkage ensures that the flow regulation and air cooling start / stop are strictly synchronized with the system liquid flow speed, achieving adaptive control of heat dissipation on demand.

[0034] 2. The integrated liquid cooling assembly and method for server fasteners with integrated heat dissipation fins achieves dynamic and rhythmic adjustment of the inlet cross-sectional area of ​​the liquid channel by periodically moving the liquid guide plate up and down. This causes periodic flow velocity and pressure fluctuations in the coolant flowing through the first fin, effectively disrupting the stable stagnant thermal boundary layer on the fin surface and significantly enhancing the instantaneous convective heat transfer coefficient on the liquid cooling side. Simultaneously, the airflow generated by the fan blade rotation provides auxiliary air cooling for the second fin, forming a composite cooling mechanism with liquid cooling as the main component, dynamic turbulence enhancement, and air cooling as a supplement, thus jointly improving the peak heat dissipation capacity of the cooling plate in a limited space.

[0052] 500. Liquid supply system. Detailed Implementation

[0053] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this invention. All embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0054] Please see Figures 1-2As shown, this embodiment provides the following technical solution:

[0055] The integrated liquid cooling assembly for server fasteners with integrated heat dissipation fins includes a cooling system 400. A base plate 100 is fixedly connected to the bottom of the cooling system 400 by screws. A top plate 200 is snapped onto the top of the base plate 100. A computing card 300 is also snapped onto the base plate 100 and the cooling system 400. A liquid supply system 500 connected to an external refrigerant circulation system is fixedly connected to the inside of the base plate 100 by screws. Two pipes for refrigerant circulation in the liquid supply system 500 are fixedly connected to the inlet and outlet ends of the pipe mounting head 410 by sealing bolts.

[0056] Furthermore, the base plate 100, together with the top plate 200, provides a placement area for the computing card 300, the cooling system 400, and the liquid supply system 500. After the liquid supply system 500 is connected to the external refrigerant circulation system, the refrigerant can circulate in the cooling system 400.

[0057] The above configuration constitutes the basic support and liquid supply framework of the server liquid cooling functional module. Through the cooperation of the base plate 100, the top plate 200 and the liquid supply system 500, a stable and reliable installation platform and liquid cooling circulation inlet are provided for the computing card 300 and the integrated cooling system 400.

[0058] Please see Figure 3 As shown, in this embodiment, the cooling system 400 includes a pipe mounting head 410, a driver 420, a main cooling assembly 430, a first auxiliary cooling assembly 440 and a second auxiliary cooling assembly 450 disposed outside the main cooling assembly 430, a liquid-passing pipe 460 connected between the pipe mounting head 410, the driver 420, the main cooling assembly 430, the first auxiliary cooling assembly 440 and the second auxiliary cooling assembly 450, a fastening plate 470 welded to the outer wall of the main cooling assembly 430, the first auxiliary cooling assembly 440 and the second auxiliary cooling assembly 450, and two heat-conducting copper pipes 480 snapped and fixed to the top surface of the second auxiliary cooling assembly 450.

[0059] Furthermore, after the computing card 300 is installed and fixed in the designated position inside the base plate 100, the fastening plate 470 in the cooling system 400 is fixedly connected to the inside of the base plate 100 by screws. The bottom surfaces of the main cooling component 430, the first auxiliary cooling component 440, and the second auxiliary cooling component 450 are in close contact with the key heat-generating chip positions on the computing card 300. After the external coolant circulation system is started, the coolant can circulate between the main cooling component 430, the first auxiliary cooling component 440, and the second auxiliary cooling component 450 through the liquid pipe 460, expanding the cooling of the heat-generating areas on the computing card 300. The heat-conducting copper pipe 480 further directs the locally accumulated heat to an area with a larger heat dissipation area, thereby ensuring that the heat is rapidly dissipated.

[0060] The above configuration realizes the modularity and functional zoning of the cooling system 400. The main cooling component 430 targets the core heat source, while the first auxiliary cooling component 440 and the second auxiliary cooling component 450 expand the heat dissipation coverage. Combined with the structural reinforcement of the fastening plate 470 and the auxiliary heat dissipation of the heat-conducting copper pipe 480, it forms an efficient, complete and structurally stable integrated heat dissipation module.

[0061] Please see Figures 4-6 As shown, in this embodiment, the driver 420 includes a liquid passage pipe 422, a propeller 423 rotating inside the liquid passage pipe 422, a toggle assembly 424 disposed above the propeller 423, a blower chamber 425 disposed on the top of the toggle assembly 424, and a fan blade 426 rotating inside the blower chamber 425. The end of the central shaft on the bottom surface of the fan blade 426 is engaged and fixed to the propeller 423. After the refrigerant passes through the liquid passage pipe 422, it drives the propeller 423 to rotate, which in turn drives the fan blade 426 to rotate and generate airflow in the blower chamber 425.

[0062] Specifically, the actuator 420 also includes a liquid passage chamber 421. The top surface of the liquid passage chamber 421 is welded with an inlet 4210 that communicates with the liquid inlet end of the pipe body mounting head 410. The liquid passage pipe 422 is snapped and fixed inside the round hole on the top surface of the liquid passage chamber 421. The outer wall of the liquid passage pipe 422 is provided with an outlet 4220 for the liquid passage pipe 460 to be snapped and fixed.

[0063] Furthermore, the actuation assembly 424 includes a cam 4242 that is snapped and fixed to the outer wall of the central shaft at the bottom surface of the fan blade 426, a slide rod 4243 whose end abuts against the cam 4242, a spring 4244 sleeved on the outside of the slide rod 4243, and a lever 4245 that moves with the slide rod 4243. After the cam 4242 rotates, it cooperates with the spring 4244 to drive the slide rod 4243 and the lever 4245 to reciprocate laterally.

[0064] Furthermore, the actuating assembly 424 also includes a sealing chamber 4240 that is snapped and fixed at the top end of the liquid inlet 422, and a cover plate 4241 that is fixed to the top surface of the sealing chamber 4240 by screws. The cam 4242 is rotatably connected to the inner bottom surface of the sealing chamber 4240, and the slide rod 4243 is slidably connected to the circular protrusion on the outer wall of the sealing chamber 4240 and its end extends to the outside of the sealing chamber 4240.

[0065] Furthermore, the outer wall of the slide rod 4243 is integrally formed with a circular baffle. The two ends of the spring 4244 abut against the inner wall of the circular protrusion on the outer wall of the sealing chamber 4240 and the circular baffle on the outer wall of the slide rod 4243. The elastic force provided by the spring 4244 pushes the slide rod 4243 to move towards the cam 4242. The transverse section of the lever 4245 is T-shaped and one end is locked and fixed to the slide rod 4243.

[0066] Furthermore, the blower chamber 425 is snapped and fixed to the top surface of the sealing chamber 4240, and a filter screen is snapped into the round hole opened above the fan blade 426 on the top surface of the blower chamber 425. A ventilation chamber 427 is also snapped and fixed to the outside of the air outlet of the blower chamber 425.

[0067] Furthermore, the refrigerant circulates within the cooling system 400; the refrigerant flows from the liquid inlet 421 into the liquid inlet pipe 422, drives the propeller 423 to rotate by fluid kinetic energy, then flows through the liquid outlet 4220 into the liquid inlet pipe 460, and finally enters the main cooling component 430.

[0068] When the propeller 423 rotates, it drives the cam 4242 above it to rotate synchronously via its central shaft. During the rotation, the cam 4242 periodically pushes against the slide rod 4243, and in conjunction with the restoring action of the spring 4244, causes the slide rod 4243 to drive the lever 4245 to perform horizontal reciprocating motion. At the same time, the propeller 423 drives the fan blades 426 to rotate synchronously within the blower chamber 425 via its central shaft, and the resulting airflow is introduced into the main cooling assembly 430 through the ventilation chamber 427.

[0069] The core of the above setup is that the driver 420 converts the kinetic energy of the fluid into mechanical reciprocating motion through the mechanism of cam 4242 and spring 4244, and drives the fan blades 426 to generate cooling airflow, thus realizing a multi-functional, highly integrated self-driven operation.

[0070] Please see Figures 7-12 As shown, in this embodiment, the main cooling component 430 includes a cooling plate 431. The cooling plate 431 has two layers of channels inside, the upper layer being a ventilation channel 4313 for airflow and the lower layer being a liquid channel 4312 for refrigerant flow.

[0071] Specifically, the main cooling assembly 430 also includes several first fins 433 distributed in the liquid channel 4312, several second fins 434 distributed in the liquid channel 4312 and the ventilation channel 4313, and a liquid guide plate 435 sliding at the liquid inlet of the liquid channel 4312. The bottom surface of the liquid guide plate 435 is provided with two grooves 4350. When the lever 4245 moves back and forth, the end of the lever 4245 moves along the groove 4350, driving the liquid guide plate 435 to move up and down, thereby adjusting the inflow section of the coolant.

[0072] Furthermore, on the outer walls of the left and right sides of the cooling plate 431, liquid inlet head 4310 and liquid outlet head 4311 are respectively provided, which are connected to the liquid passage 4312. Liquid passage pipes 460 are fixedly connected to the inner side of the liquid inlet head 4310 and the liquid outlet head 4311. The outer side of the air inlet of the ventilation slot 4313 is fixedly connected to the end opening of the ventilation chamber 427. A filter screen is fixedly connected to the outer side of the air outlet of the ventilation slot 4313.

[0073] Furthermore, the main cooling assembly 430 also includes a heat-conducting plate 432 that is fixedly connected to the bottom surface of the cooling plate 431 by screws. The first fin 433 is integrally formed with the heat-conducting plate 432, the second fin 434 is welded and fixed to the cooling plate 431, and the longitudinal section of the liquid guide plate 435 is bent. When the liquid guide plate 435 is in the lowest position, the horizontal height of its end is higher than the maximum height when the refrigerant passes through.

[0074] Furthermore, the refrigerant enters the liquid channel 4312 through the inlet 4310 of the cooling plate 431 and then flows out through the outlet 4311. The airflow generated by the rotation of the propeller 423 is guided into the ventilation slot 4313 of the cooling plate 431 through the ventilation chamber 427, and forced convection cooling is performed on the second fins 434 distributed in the ventilation slot 4313; thus, auxiliary air cooling of the cooling plate 431 is achieved. The heat-conducting plate 432 is used to contact the main chip in the computing card 300. The end of the lever 4245 is embedded in the lever groove 4350 on the bottom surface of the liquid guide plate 435, thereby converting the horizontal movement into the vertical movement of the liquid guide plate 435, thereby dynamically adjusting the opening of the liquid inlet of the liquid channel 4312. This periodic change in opening disturbs the flow field of the coolant flowing through the liquid channel 4312, thereby destroying the stagnant thermal boundary layer on the surface of the first fin 433, thereby improving the instantaneous heat exchange efficiency.

[0075] The above configuration enables the main cooling component 430 to achieve composite heat dissipation and intelligent adjustment. Through the physical integration and synergy of liquid cooling and air cooling, combined with the periodic dynamic turbulence of the liquid guide plate 435, the heat dissipation efficiency and thermal balance in a compact space are significantly improved.

[0076] The integrated liquid cooling method for server fasteners with integrated heat dissipation fins of the present invention, using the above-mentioned integrated liquid cooling assembly for server fasteners with integrated heat dissipation fins, includes the following steps:

[0077] S1. First, install and fix the computing card 300 to the designated position inside the base plate 100, and fix the fastening plate 470 in the cooling system 400 to the inside of the base plate 100 with screws, ensuring that the bottom surfaces of the main cooling component 430, the first auxiliary cooling component 440 and the second auxiliary cooling component 450 are in close contact with the key heat-generating chip positions on the computing card 300; then complete the installation of the liquid supply system 500, and connect the circulation pipe in the liquid supply system 500 to the inlet and outlet ends of the pipe mounting head 410 with sealing bolts; finally, install the top plate 200 on the top of the base plate 100 to complete the assembly of a single liquid cooling functional component;

[0078] S2. Subsequently, several sets of assembled liquid cooling functional components are inserted side by side into the corresponding slots of the server chassis, and the main pipe of the external refrigerant circulation system is connected in parallel with the liquid supply system 500 in each component to complete the integrated installation of the entire liquid cooling system in the server.

[0079] S3. Then, the external refrigerant circulation system is started, and the refrigerant circulates in the cooling system 400. The refrigerant flows from the liquid inlet 421 into the liquid inlet pipe 422, drives the propeller 423 to rotate by the fluid kinetic energy, and then flows into the liquid outlet 4220 into the liquid inlet pipe 460, and finally enters the main cooling component 430.

[0080] S4. When the propeller 423 rotates, it drives the cam 4242 above it to rotate synchronously through its central shaft. During the rotation, the cam 4242 periodically pushes against the slide rod 4243, and combined with the reset action of the spring 4244, the slide rod 4243 drives the lever 4245 to perform horizontal reciprocating motion. The end of the lever 4245 is embedded in the groove 4350 on the bottom surface of the liquid guide plate 435, thereby converting the horizontal motion into the vertical motion of the liquid guide plate 435, thereby dynamically adjusting the opening of the liquid inlet of the liquid channel 4312. This periodic change in opening disturbs the flow field of the coolant flowing through the liquid channel 4312, thereby destroying the stagnant thermal boundary layer on the surface of the first fin 433, thereby improving the instantaneous heat exchange efficiency.

[0081] S5. At the same time, the propeller 423 drives the fan blades 426 to rotate synchronously in the blower chamber 425 through the central shaft. The airflow generated is introduced into the ventilation slots 4313 of the cooling plate 431 through the ventilation chamber 427, and forced convection cooling is performed on the second fins 434 distributed in the ventilation slots 4313.

9. The integrated liquid cooling method of server fastener with heat dissipation fins, using the integrated liquid cooling device of server fastener with heat dissipation fins according to claim 8, characterized in that, Includes the following steps: S1. First, install and fix the computing card to the designated position inside the base plate, and fix the fastening plate of the cooling system to the inside of the base plate with screws, ensuring that the bottom surfaces of the main cooling component, the first auxiliary cooling component, and the second auxiliary cooling component are in close contact with the key heat-generating chip positions on the computing card; then complete the installation of the liquid supply system, and connect the circulation pipe of the liquid supply system to the inlet and outlet ends of the pipe body mounting head with sealing bolts; finally, install the top plate on the top of the base plate to complete the assembly of a single liquid cooling functional component; S2. Subsequently, several sets of assembled liquid cooling functional components are inserted side by side into the corresponding slots of the server chassis, and the main pipe of the external refrigerant circulation system is connected in parallel with the liquid supply system in each component to complete the integrated installation of the entire liquid cooling system in the server. S3. Then, the external refrigerant circulation system is started, and the refrigerant circulates in the cooling system. The refrigerant flows from the liquid inlet into the liquid pipe, drives the propeller to rotate by fluid kinetic energy, and then flows into the liquid pipe through the liquid outlet, and finally enters the main cooling component. S4. When the propeller rotates, it drives the cam above to rotate synchronously through its central shaft. During the rotation, the cam periodically pushes against the slide rod, and combined with the reset action of the spring, the slide rod drives the lever to perform horizontal reciprocating motion. The end of the lever is embedded in the groove on the bottom surface of the liquid guide plate, thereby converting the horizontal motion into the vertical motion of the liquid guide plate, so as to dynamically adjust the opening of the liquid inlet of the liquid channel. This periodic change in opening disturbs the flow field of the coolant flowing through the liquid channel, thereby destroying the stagnant thermal boundary layer on the surface of the first fin. S5. At the same time, the propeller drives the fan blades to rotate synchronously in the blower chamber through the central shaft. The airflow generated is introduced into the ventilation slots of the cooling plate through the ventilation chamber, and forced convection cooling is performed on the second fins distributed in the ventilation slots. This achieves auxiliary air cooling of the cooling plate and improves the overall heat dissipation performance through synergy with liquid cooling. S6. After carrying heat, the coolant flowing through the main cooling component enters the first and second auxiliary cooling components in sequence through the outlet head and the liquid flow pipe, expanding the cooling of the heat-generating area on the computing card; the heat-conducting copper pipe directs the locally accumulated heat to an area with a larger heat dissipation area, thereby ensuring that the heat is quickly dissipated.
