Description

Technical Field

[0001] This invention relates to the field of liquid cooling radiator technology, specifically an integrated liquid cooling radiator. Background Technology

[0002] A water-cooled radiator uses a liquid that is forced to circulate under the drive of a pump to remove heat from the radiator. Compared with air cooling, it has advantages such as quiet operation, stable cooling, and less dependence on the environment. The heat dissipation performance of a water-cooled radiator is directly proportional to the flow rate of the coolant (water or other liquid), which in turn is related to the power of the water pump in the refrigeration system.

[0003] The existing patent (publication number: CN116931698B) discloses an integrated liquid cooling radiator, which divides the interior of the second liquid box at the lower end of the liquid cooling radiator into a cold liquid chamber and a hot liquid chamber using a heat-insulating space. This prevents the hot working fluid in the hot liquid chamber from transferring heat to the cold working fluid in the cold liquid chamber, thereby improving the cooling effect of the liquid cooling radiator.

[0004] However, the above technical solution still has certain defects. When the device circulates coolant, it relies on a single circulation path. Under high load operation, although the coolant flow rate increases due to the increase in water pump power, the heat dissipation path is fixed and cannot be flexibly adjusted according to load changes. This results in some areas having excessive coolant flow and others having insufficient flow, causing uneven heat dissipation of the radiator as a whole. It cannot effectively cope with the heat generated by high load and is prone to equipment damage or performance degradation due to local overheating. Therefore, an integrated liquid-cooled radiator is proposed. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes an integrated liquid-cooled heat sink that can flexibly switch between single-tube circulation or multi-tube parallel operation modes according to actual heat dissipation requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated liquid-cooled radiator, comprising a radiator body, an upper liquid box at the top of the radiator body, a lower liquid box at the bottom of the radiator body, and a circulating heat dissipation component inside the radiator body; The circulating heat dissipation assembly includes a three-way liquid pump installed inside the upper liquid box. The three-way liquid pump has a first liquid port at its bottom end, and a second liquid port and a third liquid port on its two sides, respectively. The bottom end of the first liquid port is connected to a vertical pipe, which extends into the interior of the radiator body. Multiple sets of first flow tubes are arrayed on one side of the vertical pipe, and multiple sets of second flow tubes are arrayed on the side of the vertical pipe away from the first flow tubes. Both the first and second flow tubes are installed inside the radiator body. The side of the first flow tube away from the vertical pipe has an inlet pipe, and the side of the second flow tube away from the vertical pipe has an outlet pipe. Diverter pipes are installed alternately between the vertical pipe, the first flow tube, the inlet pipe, and the second flow tubes. Vertical shafts are provided inside the first flow tube, the inlet pipe, and the second flow tubes. Three sets of interlocking spiral blades are fixed to the outer wall of the multiple sets of vertical shafts. The length of the spiral blades gradually decreases from the inside to the outside around the vertical pipe as the axis.

[0007] As a preferred technical solution, the upper liquid box is provided with a first chamber, and the lower liquid box is provided with a second chamber. Two sets of first electromagnets are installed in both the first and second chambers. A matching second electromagnet is provided on one side of the first electromagnet. The second electromagnets are respectively installed on the upper and lower ends of the first and second flow tubes.

[0008] As a preferred technical solution, the upper and lower ends of the vertical pipe, the first flow pipe, the inlet pipe, the second flow pipe, and the outlet pipe are all connected to the upper liquid box and the lower liquid box.

[0009] As a preferred technical solution, an electromagnetic valve is installed on the first liquid port, and a first partition plate fixed inside the first chamber is provided on the outside of the second and third liquid ports.

[0010] As a preferred technical solution, a one-way valve is installed at the bottom end of the vertical pipe and the connection end of the second chamber, a cooling liquid device is installed at the bottom of the lower liquid box, a first liquid inlet is provided on both sides of the bottom of the lower liquid box, a second liquid inlet is provided between the two sets of first liquid inlets and the bottom of the lower liquid box, both the first liquid inlet and the second liquid inlet are connected to the cooling liquid device, and a second partition plate fixed to the inside of the second chamber is provided on both sides of the top of the second liquid inlet.

[0011] As a preferred technical solution, the bottom of the vertical tube is located between two sets of second partitions, and heat dissipation fins installed on the radiator body are provided between the multiple sets of first flow tubes and the multiple sets of second flow tubes.

[0012] As a preferred technical solution, the first electromagnet is connected to an external power source, and the second electromagnet is provided with a sealing ring on the side near the shunt tube for sealing the upper and lower ports of the first and second shunt tubes.

[0013] As a preferred technical solution, flow-breaking blocks are fixed at both the upper and lower ends of the multiple sets of spiral blades.

[0014] In summary, the present invention has the following main beneficial effects: This invention utilizes a three-way liquid pump. Under normal operating conditions, coolant is drawn into the vertical pipe through the first liquid port, allowing it to flow into both sides of the first chamber through the second and third liquid ports. Subsequently, the coolant flows from the first chamber into the first flow pipe, the second flow pipe, the inlet pipe, and the outlet pipe. When the load inside the radiator is high, closing the first liquid port and sealing the upper and lower ports of the first and second flow pipes allows the coolant to continue circulating through the branch pipe into the connected pipes. This circulation method forms a bent circulation loop, effectively handling the heat generated by high loads and ensuring that the radiator maintains stable heat dissipation performance under high load conditions, preventing equipment damage or performance degradation due to overheating.

[0015] This invention uses coolant to drive the internal spiral blades to rotate, which can agitate and propel the coolant, creating a turbulent flow state within the pipe. This greatly increases the contact area and contact time between the coolant and the pipe wall and the spiral blades, thereby significantly improving heat exchange efficiency. At the same time, due to the variation in the length of the spiral blades, the coolant entering from different pipe positions has a differentiated flow path, making the flow of coolant in each pipe more uniform and avoiding local overheating or insufficient cooling.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of the present invention will now be described.

[0020] An integrated liquid-cooled heat sink, such as Figures 1 to 8 As shown, it includes a radiator body 100, an upper liquid box 120 at the top of the radiator body 100, a lower liquid box 130 at the bottom of the radiator body 100, and a circulating heat dissipation assembly 200 inside the radiator body 100. The circulating heat dissipation assembly 200 includes a three-way liquid pump 210 installed inside the upper liquid box 120. The three-way liquid pump 210 has a first liquid port 211 at its bottom end, and a second liquid port 212 and a third liquid port 213 on its two sides, respectively. The bottom end of the first liquid port 211 is connected to a vertical pipe 240, which extends into the heat sink body 100. Multiple sets of first flow tubes 250 are arrayed on one side of the vertical pipe 240, and the vertical pipe 240 is far away from the first flow tubes 250. One side of the 0 array has multiple sets of second flow tubes 260. Both the first flow tube 250 and the second flow tube 260 are installed inside the radiator body 100. The first flow tube 250 has an inlet pipe 251 on the side away from the vertical pipe 240, and the second flow tube 260 has an outlet pipe 261 on the side away from the vertical pipe 240. Flow dividers 290 are installed alternately between the vertical pipe 240, the first flow tube 250, the inlet pipe 251, and the second flow tube 260. The first flow tube 250... Both the inlet pipe 251 and the second flow pipe 260 are equipped with vertical shafts 2910. Three sets of interlocking spiral blades 2920 are fixed on the outer wall of each set of vertical shafts 2910. The length of the spiral blades 2920 gradually decreases from the inside to the outside around the vertical pipe 240. Flow-breaking blocks 2930 are fixed at both the upper and lower ends of each set of spiral blades 2920. The upper liquid box 120 is equipped with a first chamber 121, and the lower liquid box 130 is equipped with a second chamber 131. Two sets of first electromagnets 270 are installed in both the first chamber 121 and the second chamber 131. A matching second electromagnet 280 is provided on one side of the first electromagnet 270. The second electromagnets 280 are respectively installed on one side of the upper and lower ends of the first flow pipe 250 and the second flow pipe 260. The bottom of the vertical pipe 240 is located between two sets of second partitions 241. Heat dissipation fins 110 installed on the radiator body 100 are provided between each set of first flow pipes 250 and each set of second flow pipes 260.

[0021] When the device is in operation, by starting the three-way liquid pump 210, under normal operating conditions, coolant is drawn into the vertical pipe 240 through the first liquid port 211, and the coolant flows into both sides of the first chamber 121 through the second liquid port 212 and the third liquid port 213. Then, it flows from the first chamber 121 into the first flow pipe 250, the second flow pipe 260, the inlet pipe 251 and the outlet pipe 261 respectively. The coolant will be divided into three streams and flow in the inter-channel. While flowing, it will drive the internal spiral blades 2920 to rotate, which can generate a stirring and spiral propulsion effect on the coolant, so that the coolant forms a turbulent state in the pipe. This greatly increases the contact area and contact time between the coolant and the pipe wall and the spiral blades 2920, thereby significantly improving the heat exchange efficiency. Meanwhile, the flow-breaking blocks 2930 fixed at both ends of the spiral blade 2920 can further break the laminar boundary layer during coolant flow, reduce thermal resistance, and allow heat to be transferred from the radiator body 100 to the coolant more quickly. At the same time, since multiple sets of pipes are arranged horizontally in the radiator body 100, the flow rate and velocity of the coolant entering the pipes are different. When the coolant comes into contact with the spiral blade 2920, due to the change in the length of the spiral blade 2920 (the staff designed the length of the spiral blade 2920 according to the experimental conditions to ensure that the flow velocity in each set of pipes reaches a relatively balanced state), the coolant entering from different pipe positions will have a differentiated flow path, making the flow of coolant in each pipe more uniform and avoiding local overheating or insufficient cooling. When the load inside the radiator body 100 is large, the first liquid port 211 is closed by controlling the solenoid valve 220. Simultaneously, the first electromagnet 270 is energized, generating magnetism that attracts the cooperating second electromagnet 280. The second electromagnet 280 then moves the sealing ring 281, thereby sealing the upper and lower ports of the first and second flow pipes 250 and 260. At this time, coolant is pumped from the outlet pipe 261 by the three-way pump 210 and then discharged from the third liquid port 213 into the inlet pipe 251. Because each set of pipes is connected by a branch pipe 290, the coolant will... The diverter pipe 290 enters the connected pipe to continue circulating. This circulation method can form a bent circulation loop, which can effectively deal with the heat generated by high load and ensure that the radiator body 100 can maintain stable heat dissipation performance under high load operation. It will not cause equipment damage or performance degradation due to overheating. The device can flexibly switch between single-pipe circulation or multi-pipe parallel operation mode according to actual heat dissipation needs. At the same time, it works in conjunction with the heat dissipation fins 110 to improve the heat dissipation performance of the entire radiator body 100, ensuring that the equipment can maintain a stable temperature during long-term operation and guaranteeing the normal operation and service life of the equipment.

[0022] Please refer to this carefully. Figure 3 and Figure 4The vertical pipe 240, the first flow pipe 250, the inlet pipe 251, the second flow pipe 260 and the outlet pipe 261 are all connected to the upper liquid box 120 and the lower liquid box 130 at both ends. A solenoid valve 220 is installed on the first liquid port 211. The second liquid port 212 and the third liquid port 213 are provided with a first partition 230 fixed inside the first chamber 121 on the outside.

[0023] By setting the first partition 230 to divide the first chamber 121 into different areas, the coolant flowing out from the second liquid port 212 and the third liquid port 213 can flow along a predetermined path, avoiding chaotic flow of coolant in the first chamber 121, and ensuring that the coolant can enter the first flow pipe 250 and the second flow pipe 260 and other pipes in an orderly manner, further improving the stability and reliability of the entire heat dissipation system.

[0024] Please refer to this carefully. Figures 1 to 4 A one-way valve is installed at the bottom end of the vertical pipe 240 and the connection end of the second chamber 131. A cooling liquid device 140 is installed at the bottom of the lower liquid box 130. First liquid inlets 242 are provided on both sides of the bottom of the lower liquid box 130. A second liquid inlet 243 is provided between the two sets of first liquid inlets 242 at the bottom of the lower liquid box 130. Both the first liquid inlets 242 and the second liquid inlets 243 are connected to the cooling liquid device 140. Second partitions 241 fixed inside the second chamber 131 are provided on both sides of the top of the second liquid inlet 243.

[0025] After completing heat exchange, the coolant enters the second chamber 131 of the lower liquid box 130. The one-way valve installed at the connection end between the bottom of the vertical pipe 240 and the second chamber 131 can prevent the coolant from flowing back and ensure that the coolant flows in the set direction. The cooling device 140 installed at the bottom of the lower liquid box 130 can cool the heated coolant in time, so that the coolant can regain its efficient heat dissipation capacity. Then the coolant can be drawn again by the three-way liquid pump 210 to enter the circulating heat dissipation process, thus forming a continuous and stable heat dissipation cycle.

[0026] Please refer to this carefully. Figures 2 to 8 The first electromagnet 270 is connected to an external power source, and the second electromagnet 280 is provided with a sealing ring 281 on the side near the shunt tube 290 for sealing the upper and lower ports of the first shunt tube 250 and the second shunt tube 260.

[0027] By setting a sealing ring 281 on the second electromagnet 280, when the first electromagnet 270 is energized, it can be made to fit tightly against the ports of the first flow tube 250 and the second flow tube 260, thus achieving a good sealing effect.

[0028] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
