Description

Technical Field

[0001] The utility model relates to the technical field of water cooling, in particular to a liquid flow structure, a water cooling head and a radiator. Background Art

[0002] A water cooling head refers to a component that uses forced circulation of liquid to remove heat. Water cooling heads are mainly used for small heating components, such as server chips, laser equipment, etc.

[0003] The water cooling head is an important component in the water cooling system. Its main function is to transfer heat to the water cooling head through direct contact with the heat-generating electronic components, and take away the heat through the coolant inside the water cooling head. The integrated water cooling head integrates the water cooling head, water pump and control circuit into one, with the characteristics of compact structure and layout. The use of an integrated heat dissipation water cooling head can greatly simplify the water cooling system. A simple water cooling system can be composed of an integrated water cooling head, a connecting hose and a water cooling radiator with an integrated fan.

[0004] The Chinese invention with publication number CN116075125A discloses an integrated water-cooled head, comprising: a motor assembly, a fixed base, a heat exchange plate, an impeller, and a return pipe; the motor assembly is fixedly connected and sealed to the upper end surface of the fixed base, the heat exchange plate is fixedly connected and sealed to the lower end surface of the fixed base, a cavity is formed after the fixed base and the heat exchange plate are fixedly connected, and a circumferentially arranged guide vane is fixedly connected to the heat exchange plate, and the guide vane divides the cavity into an inner ring impeller operating area and an outer ring annular water pressure chamber; the impeller is fixedly connected to the output shaft of the motor assembly and is located in the impeller operating area; the return pipe connects the annular water pressure chamber and the motor assembly from the outside of the integrated water-cooled head; an inlet channel and an outlet channel of the coolant are arranged on the fixed base, the inlet channel is connected to the inlet of the impeller, and the outlet channel is connected to the annular water pressure chamber.

[0005] In the above scheme, the impeller is arranged in the cavity, and all the water-cooling channels are formed in the cavity. During the heat dissipation process, the negative pressure is generated in the cavity by the rotation of the impeller to realize the flow of liquid. Since the impeller comes into contact with the liquid when it rotates, the liquid collides with the heat sink in the cavity to produce a large amount of cavitation, and the contact area with the impeller is large, which is easy to corrode the impeller and cause damage to the impeller.

[0036] The utility model is described in detail below with reference to the accompanying drawings.

[0037] like Figure 1-5 As shown, the liquid flow structure includes a fixed base 11, the fixed base 11 is formed with a first flow chamber 12 and a second flow chamber 13, the first flow chamber 12 is equipped with a rotatable impeller 14; the fixed base 11 is formed with a first inlet 15 and a first outlet 16 connected to the first flow chamber 12, and a second inlet 17 and a second outlet 18 are formed between the first flow chamber 12 and the second flow chamber 13.

[0038] The water-cooling liquid flows into the first flow chamber 12 through the first inlet 15, and is discharged through the first outlet 16 under the drive of the impeller part 14, so as to realize the heat dissipation of the water-cooling liquid. In this scheme, after the water-cooling liquid enters the first flow chamber 12, it will flow into the second flow chamber 13 through the second inlet 17, and then flow to the first outlet 16 through the second outlet 18 for discharge. During the heat dissipation process, the contact area between the water-cooling liquid and the impeller part 14 is reduced, which is beneficial to the protection of the impeller part 14. Secondly, since the flow area of ​​the water-cooling liquid in the first flow chamber 12 is reduced, the cavitation phenomenon generated by it will be reduced, and the corrosion to the impeller part 14 will be greatly reduced, and it is not easy to damage the impeller part 14. In addition, the water-cooling liquid also flows through the second flow chamber 13. Compared with the traditional single flow chamber, the flow area is increased, the heat dissipation effect of the water-cooling liquid is further increased, and the overall heat dissipation effect is better.

[0039] The first flow chamber 12 is provided with an impeller area 2, a first temporary storage area 21 and a second temporary storage area 22 separated from the impeller area 2. After the first temporary storage area 21 and the second temporary storage area 22 are separated from the impeller area 2, the water-cooling liquids in the corresponding areas will not be interconnected.

[0040] The first temporary storage area 21 is connected to the first inlet 15, and the second temporary storage area 22 is connected to the first outlet 16. The water-cooling liquid flows into the first flow cavity 12 through the first inlet 15 and is collected in the first temporary storage area 21. Correspondingly, the water-cooling liquid that needs to be discharged is collected in the second temporary storage area 22 and then discharged through the first outlet 16.

[0041] The second temporary storage area 22 is also connected to the second outlet 18. The water-cooling liquid passing through the second flow cavity 13 will be discharged to the second temporary storage area 22 through the second outlet 18. The first outlet 16 connected to the second temporary storage area 22 will discharge the water-cooling liquid to achieve liquid exchange.

[0042] One of the embodiments: a water-cooled head 1 includes a liquid flow structure and a sealing cover body 23 connected to a fixed base 11. The sealing cover body 23 is formed by copper material and has good thermal conductivity. A copper bottom contact surface 24 is formed on the front of the sealing cover body 23, and a heat dissipation serration 25 is formed on the back of the sealing cover body 23. The heat dissipation serration 25 is coaxially aligned with the first flow cavity 12. The first flow cavity 12 is provided with a heat dissipation copper part 3 for liquid to pass through. The water-cooled head 1 contacts the electronic components that need heat dissipation through the copper bottom contact surface 24, and has a good thermal conductivity. After the water-cooled liquid enters the first flow cavity 12, it will pass through the heat dissipation serration 25 on the back of the sealing cover body 23. The heat dissipation serration 25 is fully in contact with the water-cooled liquid, thereby cooling the sealing cover body 23 and guiding the liquid to the impeller area 2 through the heat dissipation copper part 3.

[0043] Specifically, the heat dissipation copper part 3 includes a first support plate 31 and a second support plate 32 stacked in sequence from the inside to the outside, and the first support plate 31 is provided with a bottom access hole 37 connected to the first flow chamber 12; the first support plate 31 is formed with a flow area 36 connected to the bottom access hole 37, and the second support plate 32 is formed with a top access hole 35 connected to the flow area 36 of the first support plate 31; the water-cooling liquid entering the water-cooling head 1 will pass through the top access hole 35 of the second support plate 32 and then enter the flow area 36 of the first support plate 31, and then flow into the impeller area 2 through the bottom access hole 37, and the impeller part 14 of the impeller area 2 rotates to discharge the water-cooling liquid into the second flow chamber 13 to realize the flow of the water-cooling liquid. When flowing, it passes through the heat dissipation serrations 25 on the back of the sealing cover body 23 to dissipate heat to the sealing cover body 23.

[0044] Furthermore, a third support plate 33 is installed on the top of the second support plate 32 to resist the heat dissipation serrations 25. The width of the third support plate 33 is smaller than that of the second support plate 32. There is a gap for liquid flow between two opposite long sides of the third support plate 33 and the cavity wall of the first flow cavity 12; the first support plate 31, the second support plate 32 and the third support plate 33 are respectively coaxially formed with a liquid supply groove 34 connected to the first temporary storage area 21; after the water-cooling liquid enters the first temporary storage area 21 through the first inlet 15, it is sequentially along the first support plate The cooling liquid flows along the gap between the third support plate 33 and the wall of the first flow chamber 12, and then flows along the length direction of the heat dissipation serrations 25. The cooling liquid fully contacts the heat dissipation serrations 25, and the sealing cover 23 is quickly cooled. After the cooling liquid reaches the other side of the third support plate 33, it flows into the flow area 36 of the first support plate 31 through the top inlet hole 35, enters the bottom inlet hole 37 through the flow area 36, ​​and flows into the impeller area 2.

[0045] The impeller area 2 is connected to the second inlet 17 . The water-cooling liquid entering the impeller area 2 is guided to flow toward the second inlet 17 under the rotation of the impeller member 14 , and is guided into the second flow chamber 13 through the second inlet 17 .

[0046] The fixed base 11 is also formed with a U-shaped sealing groove 27, which is formed on the periphery of the first flow chamber 12. The sealing groove 27 is installed with a sealing ring 28. After the sealing cover 23 is attached to the fixed base 11, the sealing ring 28 can isolate the first flow chamber 12, and the water-cooling liquid in the first flow chamber 12 will not overflow, thereby achieving waterproofing.

[0047] One of the embodiments: a radiator includes a water-cooled head 1, a water drain 4, and a cooling fan 41 installed on the water drain 4. A first water-cooling pipe 42 and a second water-cooling pipe 43 are connected between the water drain 4 and the water-cooled head 1. The liquid after passing through the water-cooled head 1 flows into the water drain 4 through the first water-cooling pipe 42. After the water drain 4 cools the water-cooled liquid, it is returned to the water-cooled head 1 through the second water-cooling pipe 43, thereby realizing liquid circulation of the water-cooled liquid.

[0048] Preferably, the outer wall of the fixed base 11 is respectively provided with a corner joint 26 connected with the first inlet 15 and the first outlet 16, the water drain 4 is provided with a liquid inlet head 44 and a liquid outlet head 45, the first water cooling pipe 42 is connected between the corner joint 26 of the first outlet 16 and the liquid inlet head 44; the second water cooling pipe 43 is connected between the corner joint 26 of the first inlet 15 and the liquid outlet head 45; the water-cooling liquid of the water-cooling head 1 is discharged into the water drain 4 through the first water cooling pipe 42 connected with the liquid inlet head 44 under the cooperation of the first outlet 16 and the corner joint 26, the cooling fan 41 discharges the heat generated by the water drain 4 to achieve heat dissipation, and the water-cooling liquid after heat dissipation is discharged through the liquid outlet head 45, the second water cooling pipe 43 is connected with the corner joint 26 of the first inlet 15 of the water cooling head 1 to achieve the circulation of the water-cooling liquid.
