Description

Technical Field

[0001] This invention belongs to the field of liquid-cooled radiator technology, specifically relating to a liquid-cooled radiator and its liquid-cooled heat dissipation and temperature control method. Background Technology

[0002] As electronic devices become increasingly high-performance, the heat generated by CPUs continues to rise, posing a significant challenge to the design of heat dissipation structures that fit the CPU. Currently, common liquid cooling radiators mainly consist of components such as a cold block (which contacts the CPU to transfer heat), a water pump (which provides the power for coolant circulation), water pipes (which connect various components to form a circulation channel), and a radiator (which expands the heat dissipation area and accelerates heat dissipation through a fan). The cold block usually has microchannels inside, through which the coolant flows under the action of the water pump, absorbing the heat generated by the CPU, then flows to the radiator for heat dissipation, and then circulates back to the cold block.

[0003] However, existing designs have significant flaws in the crucial aspect of heat dissipation where the cold block contacts the CPU. In most current liquid cooling radiators, the flow channel layout is often simple and arbitrary, with common channel shapes being straight lines or simple serpentine arrangements. The coolant entering from the inlet flows along these fixed-shape channels. Because straight channels are too direct, the coolant passes through certain areas too quickly, resulting in insufficient contact time with surrounding heat-conducting components and inadequate heat absorption. While serpentine channels increase the flow path of the coolant to some extent, changes in the channel cross-section and flow direction at bends can easily lead to poor flow. These unreasonable channel layouts ultimately result in uneven heat distribution on the CPU surface, creating localized high-temperature "hot spots," affecting CPU performance and stability, and hindering further improvements in the heat dissipation efficiency of liquid cooling radiators.

[0004] Therefore, it is of great importance to design a liquid-cooled radiator and its liquid-cooled heat dissipation and temperature control method to solve the above-mentioned defects. Summary of the Invention

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a liquid-cooled heat sink and its liquid-cooled heat dissipation and temperature control method. This heat sink aims to solve the technical problem that the unreasonable internal flow channel layout of the cold head of existing liquid-cooled heat sinks leads to uneven heat distribution on the CPU surface, easy formation of local high-temperature "hot spots", which in turn affects CPU performance and stability and restricts the improvement of heat dissipation efficiency.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, the present invention provides a liquid-cooled radiator, which includes a coolant tank and a cold head. Cooling fans are fixedly installed on both the left and right ends of the front of the coolant tank. The cold head is composed of a pump body, a liquid guiding assembly and a CPU positioning bracket from top to bottom. The pump body is composed of a delivery pipe and a return pipe.

[0009] The liquid guiding assembly includes a fixed head fixedly installed at the bottom of the pump body, a liquid guiding plate fixedly installed at the bottom of the fixed head, a metal heat-conducting substrate fixedly installed at the bottom of the liquid guiding plate, an inlet hole at the center of the fixed head, a cooling cavity inside the metal heat-conducting substrate, a spiral guide plate fixedly connected inside the cooling cavity, forming a spiral flow channel between the spiral guide plate and the cooling cavity, the bottom end of the inlet hole connecting to the center of the spiral flow channel, outlet holes at positions corresponding to the end of the spiral flow channel inside the fixed head and the liquid guiding plate, and both the outlet holes and the inlet holes communicating with the inside of the pump body, and a one-way valve installed at the connection between the outlet holes and the inlet holes and the pump body.

[0010] When using the radiator of this technical solution, the cold head is first assembled. The mounting edge of the liquid guiding assembly fixing head is fixed to the pump body using multiple sets of first assembly screws. Simultaneously, ensure that the first sealing groove at the connection between the pump body and the fixing head is fitted with a first rubber sealing ring to prevent coolant leakage. Next, during the internal assembly of the liquid guiding assembly, a second rubber sealing ring is fitted into the second sealing groove on the side opposite to the liquid guiding plate and the metal heat-conducting substrate. A third rubber sealing ring is fitted into the positioning hole at the connection between the liquid guiding plate and the inlet hole, and the connection with the fixing head, to enhance the sealing between the parts. Then, the metal heat-conducting substrate is fixedly connected to the fixing head using multiple sets of second assembly screws. This completes the assembly of the cold head. After the cold head assembly is completed, the coolant tank and the radiator are then connected... The connection of the head involves threading the assembly connectors, which are fixed at both ends of the delivery pipe and return pipe, to the coolant tank and pump body respectively, thus establishing a coolant circulation channel. A filler cap is threaded onto one end of the coolant tank; unscrew the cap to add coolant. Then, secure the two sets of cooling fans to the left and right ends of the front of the coolant tank using the third assembly screws at the four corners, and install the protective nets to ensure proper fan operation. The CPU positioning bracket has a CPU positioning slot inside. Before installing the CPU positioning bracket under the pump body, align the CPU positioning slot inside the bracket with the CPU, ensuring it fits precisely into the slot. This guarantees a tight fit between the assembled cold head and the CPU, allowing for efficient heat transfer from the CPU to the cold head. Then, using the fourth assembly screw and positioning sleeve, the mounting feet at the four corners of the pump body are threaded to the CPU positioning bracket, ensuring the pump body and CPU positioning bracket are properly positioned and assembled. This ensures precise contact between the bottom of the metal heat-conducting substrate and the CPU coated with thermal paste. After installation, the cooling fan and pump body are started. The cooling fan continuously cools the coolant tank, and the pump body draws the coolant from the tank into the cold head through the delivery pipe. After the coolant enters the pump body, the liquid guiding assembly begins to operate. The coolant first enters the cooling chamber inside the metal heat-conducting substrate through the inlet hole at the center of the fixing head. Inside the cooling chamber, a spiral guide plate guides the coolant to flow along the spiral flow channel. During this process, the coolant fully absorbs the heat transferred from the CPU by the metal heat-conducting substrate. During operation, the heat-conducting columns within the spiral flow channel increase the contact area between the coolant and the metal heat-conducting substrate, further enhancing the heat absorption effect. After absorbing heat, the coolant reaches the end of the spiral flow channel and then flows back into the pump body through outlet holes located at corresponding positions inside the fixed head and guide plate. One-way valves installed at the connection points between the outlet holes and inlet holes and the pump body ensure that the coolant flows only in the specified direction, effectively preventing backflow. After absorbing heat from the CPU, the coolant is returned to the coolant tank via the return pipe, forming a complete circulating heat dissipation process. During heat dissipation, a temperature sensor inside the control box on top of the pump body monitors the temperature information in real time and transmits it to the controller. The controller intelligently adjusts the pump's operating status based on the temperature information and displays the temperature information on the display screen.This ensures the cooling system operates efficiently and stably at all times, providing reliable heat dissipation support for the CPU.

[0011] Preferably, the outer side of the fixed head is fixedly connected to an installation edge, which is fixedly connected to the pump body by multiple sets of first assembly screws. A first sealing groove is provided at the connection between the pump body and the fixed head, and a first rubber sealing ring is embedded inside the first sealing groove.

[0012] Furthermore, a second sealing groove is provided on the side of the fixed head and the metal heat-conducting substrate opposite to the liquid guiding plate. A second rubber sealing ring is embedded inside the two sets of second sealing grooves. A positioning hole is provided at the connection between the liquid guiding plate and the inlet hole. A third rubber sealing ring is embedded at the connection between the positioning hole and the fixed head.

[0013] Furthermore, the metal thermally conductive substrate is fixedly connected to the fixing head by multiple sets of second mounting screws, and multiple sets of thermally conductive pillars are fixedly connected inside the spiral flow channel.

[0014] Furthermore, the coolant tank has liquid storage chambers at both ends, and multiple sets of connecting pipes are fixedly connected inside the coolant tank and between the two sets of liquid storage chambers. Multiple sets of heat dissipation fins are fixedly connected inside the coolant tank and between the multiple sets of connecting pipes.

[0015] Furthermore, the four corners of both cooling fans are fixedly connected to the coolant tank via third mounting screws, and protective nets are fixedly installed on the outside of both cooling fans.

[0016] Furthermore, a control box is fixedly installed on the top of the pump body. The control box integrates a temperature sensor and a controller. A display screen is embedded on the top of the control box, and the pump body, temperature sensor, and display screen are all electrically connected to the controller.

[0017] Furthermore, mounting feet are fixedly installed at the four corners of the pump body, and a fourth mounting screw is inserted inside each of the mounting feet. The bottom of each of the fourth mounting screws is threaded to the CPU positioning bracket. A positioning sleeve is fitted on the outside of each of the fourth mounting screws and between the mounting feet and the CPU positioning bracket. A CPU positioning groove is opened inside the CPU positioning bracket.

[0018] Furthermore, both ends of the delivery pipe and the return pipe are fixedly equipped with assembly joints, and multiple sets of assembly joints are threadedly connected to the coolant tank and the pump body.

[0019] To address the aforementioned technical problems, this invention also provides a liquid cooling heat dissipation and temperature control method, the specific operation steps of which are as follows:

[0020] S1. Assemble the cold head, fix the liquid guiding assembly to the pump body and seal it. Then assemble the components inside the liquid guiding assembly and enhance the sealing. Finally, fix the metal heat-conducting substrate to the fixing head 501.

[0021] S2. Connect the coolant tank and the cold head. Thread the assembly connectors at both ends of the delivery pipe and return pipe to the coolant tank and pump body respectively to build a coolant circulation channel. After adding coolant to the coolant tank 1, install the cooling fan.

[0022] S3. Make the CPU precisely embedded in the CPU positioning slot in the CPU positioning bracket. Use the fourth assembly screw and positioning sleeve to position and assemble the pump body with the CPU positioning bracket, ensuring that the bottom of the metal heat-conducting substrate is precisely attached to the CPU coated with thermal paste.

[0023] S4. Start the cooling fan and pump body to circulate the coolant and dissipate heat. At the same time, the temperature sensor monitors the temperature in real time and transmits it to the controller. The controller intelligently adjusts the working status of the pump body and displays the temperature information.

[0024] (3) Beneficial effects

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] The radiator of this invention, through the cooperative design of the pump body and the liquid guiding assembly, during the assembly of the cold head, fixes the mounting edge of the liquid guiding assembly fixing head to the pump body with multiple sets of first assembly screws. At the same time, it ensures that the first sealing groove at the connection between the pump body and the fixing head is embedded with a first rubber sealing ring to prevent coolant leakage. Then, during the internal assembly of the liquid guiding assembly, the second sealing groove located on the side opposite to the fixing head and the metal heat-conducting substrate and the liquid guiding plate is embedded with a second rubber sealing ring. The positioning hole at the connection between the liquid guiding plate and the inlet hole is embedded with a third rubber sealing ring at the connection between the fixing head and the liquid guiding plate to enhance the sealing between the parts. After that, the metal heat-conducting substrate and the fixing head are fixedly connected with multiple sets of second assembly screws, thus completing the assembly of the cold head. The modular design of the liquid guiding assembly greatly facilitates assembly and maintenance while ensuring the sealing effect.

[0027] After installing the cold block on the CPU, start the cooling fan and pump. The cooling fan continuously cools the coolant tank, while the pump draws coolant from the tank into the cold block through delivery pipes. Once inside the pump, the coolant guiding assembly begins operation. The coolant first enters the cooling chamber inside the metal thermally conductive substrate through the inlet hole at the center of the mounting head. Inside the cooling chamber, spiral guide plates guide the coolant along spiral flow channels. During this process, the coolant fully absorbs the heat transferred from the CPU to the metal thermally conductive substrate. Simultaneously, the heat-conducting pillars within the spiral flow channels increase the contact area between the coolant and the metal thermally conductive substrate, further enhancing heat absorption. The coolant, after absorbing heat, reaches the end of the spiral flow channel and then flows back into the pump body through the outlet holes opened at corresponding positions inside the fixed head and guide plate. The one-way valve installed at the connection between the outlet hole and the inlet hole and the pump body ensures that the coolant can only flow in the specified direction, effectively preventing coolant backflow. The spiral flow channel design allows the coolant to flow slowly in a spiral path, effectively solving the problems of insufficient heat absorption in existing straight flow channels and flow obstruction in serpentine flow channels. Combined with the one-way valve, it ensures stable unidirectional circulation of coolant, significantly improving heat dissipation uniformity, completely eliminating "hot spots" on the CPU surface, and greatly improving heat dissipation efficiency and CPU operating stability.

Detailed Implementation

[0039] This specific embodiment is a liquid-cooled radiator, and its structural schematic diagram is shown below. Figure 1-10 As shown, the radiator includes a coolant tank 1 and a cold head 2. Cooling fans 3 are fixedly installed on both the left and right ends of the front of the coolant tank 1. The cold head 2 consists of a pump body 4, a liquid guiding assembly 5 and a CPU positioning bracket 6 from top to bottom. The pump body 4 is composed of a delivery pipe 7 and a return pipe 8.

[0040] First, in this embodiment, the specific structure of the liquid guiding component 5 is as follows:

[0041] The liquid guiding assembly 5 includes a fixed head 501 fixedly installed at the bottom of the pump body 4. A liquid guiding plate 502 is fixedly installed at the bottom of the fixed head 501, and a metal heat-conducting substrate 503 is fixedly installed at the bottom of the liquid guiding plate 502. An inlet hole 504 is opened at the center of the fixed head 501. A cooling cavity 505 is opened inside the metal heat-conducting substrate 503. A spiral guide plate 506 is fixedly connected inside the cooling cavity 505. A spiral flow channel 507 is formed between the spiral guide plate 506 and the cooling cavity 505. The bottom end of the inlet hole 504 is connected to the center of the spiral flow channel 507. The fixed head 501 and the guide plate 504 are connected to the center of the spiral flow channel 507. An outlet hole 508 is provided inside the liquid plate 502 at a position corresponding to the end of the spiral flow channel 507. Both the outlet hole 508 and the inlet hole 504 are connected to the inside of the pump body 4. A one-way valve 509 is installed at the connection between the outlet hole 508 and the inlet hole 504 and the pump body 4. The cooling fan 3 continuously dissipates heat from the coolant tank 1. The pump body 4 draws the coolant from the coolant tank 1 into the cold head 2 through the delivery pipe 7. After the coolant absorbs heat from the CPU in the cold head 2, it is returned to the coolant tank 1 through the return pipe 8, forming a circulation for heat dissipation. After the coolant enters the pump body 4, the liquid guiding assembly 5 starts to work. After the coolant is drawn into the pump body 4, the liquid guiding assembly 5 begins to operate. The coolant first enters the cooling chamber 505 inside the metal heat-conducting substrate 503 through the inlet hole 504 at the center of the fixed head 501. Inside the cooling chamber 505, the spiral guide plate 506 guides the coolant to flow along the spiral flow channel 507. During the flow, the coolant fully absorbs the heat transferred from the CPU to the metal heat-conducting substrate 503. Subsequently, the coolant, after absorbing heat, reaches the end of the spiral flow channel 507 and then flows back to the pump through the outlet holes 508 opened at corresponding positions inside the fixed head 501 and the liquid guiding plate 502. Inside the pump body 4, the one-way valve 509 installed at the connection between the outlet hole 508 and the inlet hole 504 and the pump body 4 ensures that the coolant can only flow in the specified direction and prevents the coolant from flowing back. The spiral flow channel 507 of the liquid guiding assembly 5 allows the coolant to flow slowly in a spiral path through the spiral guide structure. It does not flow too quickly like the existing straight flow channel, which leads to insufficient local heat absorption, nor does it avoid the flow obstruction caused by the change of cross section at the bend of the existing serpentine flow channel. Together with the one-way valve 509, it ensures one-way circulation, so that the coolant can stably carry away the heat of the CPU, significantly improve the heat dissipation uniformity, and completely eliminate the "hot spot" problem.

[0042] Furthermore, an mounting edge 510 is fixedly connected to the outer side of the fixing head 501. The mounting edge 510 is fixedly connected to the pump body 4 by multiple sets of first mounting screws 511. A first sealing groove 512 is provided at the connection between the pump body 4 and the fixing head 501. A first rubber sealing ring 513 is embedded inside the first sealing groove 512. When the liquid guiding component 5 is installed to the pump body 4, the mounting edge 510 on the outer side of the fixing head 501 is fixedly connected to the pump body 4 by multiple sets of first mounting screws 511. At the same time, the first rubber sealing ring 513 is embedded in the first sealing groove 512 at the connection between the pump body 4 and the fixing head 501, which plays a sealing role. The first mounting screws 511 ensure a stable connection between the liquid guiding component 5 and the pump body 4, preventing loosening during operation. The first rubber sealing ring 513 effectively prevents the leakage of coolant, ensuring the sealing and stability of the heat dissipation system.

[0043] Then, a second sealing groove 514 is provided on the side of the fixing head 501 and the metal heat-conducting substrate 503 opposite to the liquid guiding plate 502. A second rubber sealing ring 515 is embedded inside each of the two sets of second sealing grooves 514. A positioning hole 516 is provided at the connection between the liquid guiding plate 502 and the inlet hole 504. A third rubber sealing ring 517 is embedded at the connection between the inner side of the positioning hole 516 and the fixing head 501. During the assembly of the liquid guiding assembly 5, the second sealing groove 514 on the side of the fixing head 501 and the metal heat-conducting substrate 503 opposite to the liquid guiding plate 502 is... The second sealing groove 514 is embedded with a second rubber sealing ring 515. The positioning hole 516 at the connection between the liquid guide plate 502 and the inlet hole 504 is embedded with a third rubber sealing ring 517 at the connection between the fixed head 501 and the positioning hole 516. The second rubber sealing ring 515 and the third rubber sealing ring 517 further enhance the sealing between the various parts of the liquid guide assembly 5. This facilitates the assembly between the liquid guide assembly 5 and the pump body 4, while preventing coolant leakage from the connection of various parts, ensuring that the coolant flows along the prescribed path, and improving heat dissipation efficiency.

[0044] Furthermore, the metal thermally conductive substrate 503 is fixedly connected to the fixing head 501 by multiple sets of second mounting screws 518, and multiple sets of heat-conducting pillars 519 are fixedly connected inside the spiral flow channel 507. The metal thermally conductive substrate 503 is fixedly connected to the fixing head 501 by multiple sets of second mounting screws 518. The second mounting screws 518 ensure a reliable connection between the metal thermally conductive substrate 503 and the fixing head 501, while the heat-conducting pillars 519 increase the contact area between the coolant and the metal thermally conductive substrate 503, enabling the coolant to more fully absorb the heat transferred from the metal thermally conductive substrate 503 and improve the heat dissipation effect.

[0045] The coolant tank 1 has storage chambers 101 at both its left and right ends. Multiple sets of connecting pipes 102 are fixedly connected inside the coolant tank 1 and between the two sets of storage chambers 101. Multiple sets of heat dissipation fins 103 are fixedly connected inside the coolant tank 1 and between the multiple sets of connecting pipes 102. The storage chambers 101 at both ends of the coolant tank 1 are connected through the multiple sets of connecting pipes 102. The multiple sets of heat dissipation fins 103 are fixed in the gaps between the multiple sets of connecting pipes 102. When the cooling fan 3 is working, it dissipates heat from the coolant tank 1. The heat is dissipated through the heat dissipation fins 103. The design of the storage chambers 101 and connecting pipes 102 increases the storage capacity and flow range of the coolant, enabling the coolant to circulate and dissipate heat better. The heat dissipation fins 103 increase the heat dissipation area. Together with the cooling fan 3, they ensure the heat dissipation efficiency of the coolant tank 1.

[0046] Furthermore, the two sets of cooling fans 3 are fixedly connected to the coolant tank 1 at the four corners by the third mounting screw 301, and the two sets of cooling fans 3 are fixedly installed with protective nets 302 on the outside. The two sets of cooling fans 3 are fixedly connected to the coolant tank 1 by the third mounting screw 301 at the four corners. The protective nets 302 on the outside play a protective role and also ensure the heat dissipation effect. After the cooling fans 3 are started, they blow air to cool the coolant tank 1.

[0047] Furthermore, a control box 401 is fixedly installed on the top of the pump body 4. The control box 401 integrates a temperature sensor 402 and a controller 403. A display screen 404 is embedded on the top of the control box 401. The pump body 4, the temperature sensor 402, and the display screen 404 are all electrically connected to the controller 403. The temperature sensor 402 monitors the temperature information in real time and transmits it to the controller 403. The controller 403 controls the working state of the pump body 4 according to the temperature information and displays the temperature information on the display screen 404. The temperature sensor 402 can monitor the temperature of the heat dissipation system in real time. The controller 403 intelligently controls the pump body 4 according to the temperature information to achieve a balance between energy saving and efficient heat dissipation. The display screen 404 allows users to intuitively understand the system temperature.

[0048] Secondly, mounting feet 405 are fixedly installed at the four corners of the pump body 4. Each of the mounting feet 405 has a fourth mounting screw 406 inserted inside. The bottom of each of the fourth mounting screws 406 is threaded to the CPU positioning bracket 6. A positioning sleeve 407 is fitted on the outside of each of the fourth mounting screws 406, located between the mounting feet 405 and the CPU positioning bracket 6. The CPU positioning bracket 6 has a CPU positioning groove 601 inside. The pump body 4 is threaded to the CPU positioning bracket 6 via the mounting feet 405 at the four corners and the fourth mounting screws 406. The positioning sleeve 407 on the outside of the fourth mounting screws 406 serves a positioning and buffering function. The fourth mounting screws 406 ensure a stable connection between the pump body 4 and the CPU positioning bracket 6. The positioning sleeve 407 prevents excessive squeezing and loosening during installation, ensuring the installation accuracy and stability of the pump body 4. When installing the CPU, the CPU positioning groove 601 inside the CPU positioning bracket 6 is aligned with the CPU for installation. The shape and size of the CPU positioning groove 601 match the CPU, ensuring that the cold head 2 is accurately installed in the predetermined position.

[0049] Finally, assembly joints 701 are fixedly installed at both ends of the delivery pipe 7 and the return pipe 8. Multiple sets of assembly joints 701 are threadedly connected to the coolant tank 1 and the pump body 4. The assembly joints 701 fixedly installed at both ends of the delivery pipe 7 and the return pipe 8 are threadedly connected to the coolant tank 1 and the pump body 4 respectively, forming a circulation channel for the coolant. The assembly joints 701 facilitate the connection and disassembly of the delivery pipe 7 and the return pipe 8 to the coolant tank 1 and the pump body 4, ensuring the sealing and reliability of the coolant circulation channel, and facilitating the installation and maintenance of the system.

[0050] When using the device of this technical solution, the cold head 2 is first assembled. The mounting edge 510 on the outside of the fixing head 501 of the liquid guiding assembly 5 is fixed to the pump body 4 by multiple sets of first mounting screws 511. At the same time, ensure that the first sealing groove 512 at the connection between the pump body 4 and the fixing head 501 is fitted with a first rubber sealing ring 513 to prevent coolant leakage. Next, when assembling inside the liquid guiding assembly 5, the second sealing groove 514 on the side opposite to the fixing head 501 and the metal heat-conducting substrate 503 and the liquid guiding plate 502 is fitted with a second rubber sealing ring 515. The third rubber sealing ring 517 is fitted inside the positioning hole 516 at the connection between the liquid guiding plate 502 and the inlet hole 504 and the fixing head 501 to enhance the sealing between the parts. After that, multiple The second assembly screw 518 secures the metal heat-conducting substrate 503 to the fixing head 501, thus completing the assembly of the cold head 2. After the cold head 2 is assembled, the coolant tank 1 is connected to the cold head 2. The assembly connectors 701, which are fixedly installed at both ends of the delivery pipe 7 and the return pipe 8, are threaded to the coolant tank 1 and the pump body 4, respectively, to establish a coolant circulation channel. One end of the coolant tank 1 is threaded with a filling cap. Unscrew the filling cap to add coolant. Then, the two sets of cooling fans 3 are fixedly installed on the left and right ends of the front of the coolant tank 1 using the third assembly screws 301 at the four corners, and the protective nets 302 are installed to protect the cooling fans 3 so that they can operate normally. The CPU positioning bracket 6 has a CPU positioning slot 601 inside. The CPU positioning bracket 6 is not installed yet. Position the pump body 4 below the CPU, aligning the CPU positioning slot 601 in the CPU positioning bracket 6 with the CPU, ensuring precise insertion into the CPU positioning slot 601. This guarantees that the assembled cold head 2 will fit tightly against the CPU, allowing efficient heat transfer from the CPU to the cold head 2. Then, using the fourth mounting screw 406 and positioning sleeve 407, thread the mounting feet 405 at the four corners of the pump body 4 to the CPU positioning bracket 6, positioning the pump body 4 and CPU positioning bracket 6. This ensures precise contact between the bottom of the metal heat-conducting substrate 503 and the CPU coated with thermal paste. After installation, start the cooling fan 3 and the pump body 4. The cooling fan 3 continuously cools the coolant tank 1, while the pump body 4 draws coolant from the coolant tank 1 into the cold head 2 through the delivery pipe 7. After the coolant enters the pump body 4, the liquid guiding assembly 5 begins to operate. The coolant first enters the cooling chamber 505 inside the metal heat-conducting substrate 503 through the inlet hole 504 at the center of the fixed head 501. Inside the cooling chamber 505, the spiral guide plate 506 guides the coolant to flow along the spiral flow channel 507. During this process, the coolant fully absorbs the heat transferred from the CPU by the metal heat-conducting substrate 503. At the same time, the heat-conducting pillars 519 in the spiral flow channel 507 increase the contact area between the coolant and the metal heat-conducting substrate 503, further improving the heat absorption effect. After absorbing heat, the coolant reaches the end of the spiral flow channel 507 and then flows back into the pump body 4 through the outlet holes 508 opened at corresponding positions inside the fixed head 501 and the liquid guiding plate 502.The one-way valve 509 installed at the connection between the outlet hole 508 and the inlet hole 504 and the pump body 4 ensures that the coolant can only flow in the specified direction, effectively preventing coolant backflow. After absorbing heat from the CPU, the coolant is sent back to the coolant tank 1 through the return pipe 8, forming a complete circulating heat dissipation process. During the heat dissipation process, the temperature sensor 402 in the control box 401 on the top of the pump body 4 monitors the temperature information in real time and transmits it to the controller 403. The controller 403 intelligently adjusts the working status of the pump body 4 based on the temperature information and displays the temperature information on the display screen 404, ensuring that the heat dissipation system always operates efficiently and stably, providing reliable heat dissipation support for the CPU. The entire operation process is simple and convenient. Through the modular design of the liquid guiding component 5, this invention greatly facilitates assembly and maintenance while ensuring the sealing effect. The core spiral flow channel 507 design allows the coolant to flow slowly in a spiral path, effectively solving the problems of insufficient heat absorption in existing straight flow channels and flow obstruction in serpentine flow channels. Combined with the one-way valve 509, it ensures stable one-way circulation of coolant, significantly improves heat dissipation uniformity, completely eliminates "hot spots" on the CPU surface, and greatly improves heat dissipation efficiency and CPU operating stability. ,

[0051] This invention also provides a liquid cooling heat dissipation and temperature control method, the specific operation steps of which are as follows:

[0052] S1. Assemble the cold head 2, fix the liquid guiding component 5 to the pump body 4 and seal it. Then assemble the components inside the liquid guiding component 5 and enhance the sealing. Finally, fix the metal heat-conducting substrate 503 to the fixing head 501.

[0053] S2. Connect the coolant tank 1 and the cold head 2. Thread the assembly joints 701 at both ends of the delivery pipe 7 and the return pipe 8 to the coolant tank 1 and the pump body 4 respectively to form a coolant circulation channel. After adding coolant to the coolant tank 1, install the cooling fan 3.

[0054] S3. The CPU is precisely embedded into the CPU positioning slot 601 in the CPU positioning bracket 6. The pump body 4 is positioned and assembled with the CPU positioning bracket 6 using the fourth assembly screw 406 and the positioning sleeve 407, ensuring that the bottom of the metal heat-conducting substrate 503 is precisely attached to the CPU coated with thermal paste.

[0055] S4. Start the cooling fan 3 and pump body 4 to circulate the coolant for heat dissipation. At the same time, the temperature sensor 402 monitors the temperature in real time and transmits it to the controller 403. The controller 403 intelligently adjusts the working status of the pump body 4 and displays the temperature information.

[0056] Furthermore, the control method of the present invention is controlled by the controller 403. The control circuit of the controller 403 can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since the present invention is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
