[0002] As the performance and computing power of personal computers increase, in order to ensure a good ambient temperature and prevent device overheating, the heat dissipation requirements for core computing devices such as motherboards and discrete graphics cards are also increasing.

[0003] Currently, water-cooled radiators are increasingly used in personal computers and computing servers due to their high thermal conductivity and excellent heat dissipation performance. As heat dissipation requirements increase, the heat dissipation area and air flow of water-cooled radiators are also increasing. However, since the fins of current water-cooled radiators are generally made of thin sheet materials, the increase in area and air flow can lead to increased vibration and noise from the fins.

[0004] Therefore, there is an urgent need to research and develop a heat sink structure and a water-cooled radiator using the heat sink structure that can adapt to current heat dissipation and quietness requirements. Utility Model Content

[0010] In an optional implementation, the sheet is arranged with a plurality of heat dissipation holes.

[0011] The heat dissipation efficiency of the heat sink can be improved through the design of the heat dissipation holes.

[0013] In an optional implementation, a partition is provided in the first water tank, which divides the interior of the first water tank into a first liquid chamber and a third liquid chamber. A second liquid chamber is provided in the second water tank. One end of the flat tube is connected to the first liquid chamber or the third liquid chamber, and the other end of the flat tube is connected to the second liquid chamber.

[0032] In addition, in this article, directional terms such as "upper" and "lower" are defined relative to the orientation of the structure schematically placed in the accompanying drawings.

[0033] See also Figures 1 to 4The present application provides a heat sink 10, which can be used for a water-cooled radiator or an air-cooled radiator.

[0034] The heat sink 10 provided in the present application is formed by connecting a plurality of sheets 11 in sequence. At least one side of the sheet 11 is provided with a folding portion 12 , and the folding portion 12 is extended along the edge of the sheet 11 .

[0035] The folded portion 12 is provided to enhance the structural stability of the sheet 11 , reduce vibration of the sheet 11 caused by airflow, and further reduce noise.

[0036] Example 1

[0037] Combine Figure 1 As shown, in embodiment 1, the heat sink 10 is formed by connecting a plurality of sheets 11 in sequence. Specifically, the sheets 11 are connected to form a "W" shape, which can increase the heat dissipation surface.

[0038] A folding portion 12 is provided on both sides of the sheet 11 , and the folding portion 12 extends along the edge of the sheet 11 .

[0039] By providing folding portions 12 on both sides of the sheet 11 , the structural stability of the sheet 11 can be further enhanced.

[0040] Combine Figure 2 As shown, the folded portion 12 can be formed integrally with the sheet 11 .

[0041] Specifically, the folded portion 12 is extended outward from the side of the sheet 11 and folded toward one surface of the sheet 11 , and a bent portion 13 is formed at the edge of the sheet 11 .

[0042] Through one-piece molding, during processing, it is only necessary to enlarge the side area of ​​the sheet 11 and fold it through a folding machine to form the folded portion 12, without the need for welding, gluing and other operations, thereby reducing the difficulty of processing.

[0043] Moreover, the bent portion 13 has a curved surface, which can improve the turbulent vibration of the airflow when passing through the heat sink 10 .

[0044] In the present application, the sheet 11 may be arranged with a plurality of heat dissipation holes 14. By providing the heat dissipation holes 14 on the sheet 11, it is helpful for heat dissipation airflow to pass through, thereby improving the heat dissipation of the heat sink 10.

[0045] The heat sink 10 is generally made of thin aluminum or other thin metal materials, which are generally light, easy to process, and have high thermal conductivity. However, if the heat sink 10 is provided with heat dissipation holes 14, the structural strength of the heat sink 10 may be reduced, and vibration may occur.

[0046] The heat sink 10 provided in the present application is provided with a folded portion 12 on the sheet body 11 , so that the strength of the heat sink 10 is improved, thereby enabling the heat dissipation holes 14 to be provided on the heat sink 10 .

[0047] In the present application, the heat dissipation holes 14 may be circular, triangular, quadrilateral or polygonal.

[0048] Example 2

[0049] Combine Figure 3 As shown, embodiment 2 provides a heat sink 10 with circular heat dissipation holes 14 , and the circular heat dissipation holes 14 are arranged on the sheet body 11 .

[0050] Example 3

[0051] Combine Figure 4 As shown, embodiment 3 provides a heat sink 10 with rectangular heat dissipation holes 14 , and the rectangular heat dissipation holes 14 are arranged on the sheet body 11 .

[0052] The present application also provides a water-cooled radiator, which includes a first water tank 21 and a second water tank 22 and a heat dissipation component 23 arranged between the first water tank 21 and the second water tank 22. The heat dissipation component 23 includes a plurality of flat tubes 24 arranged side by side and connecting the first water tank 21 and the second water tank 22 and a plurality of heat sinks 10 provided in the present application. The heat sinks 10 are arranged between the flat tubes 24.

[0053] The heat sink 10 adopts the structural solution provided in the present application, such as the heat sink 10 in Examples 1 to 3, or other implementation methods of the heat sink 10 in the present application.

[0054] Example 4

[0055] Example 4 provides a water-cooled radiator, which uses the heat sink 10 provided in Example 2.

[0056] Combine Figures 5 to 8 As shown, specifically, the water-cooled radiator includes a first water tank 21 and a second water tank 22 and a heat dissipation component 23 arranged between the first water tank 21 and the second water tank 22. The heat dissipation component 23 includes a plurality of flat tubes 24 arranged side by side and connecting the first water tank 21 and the second water tank 22, and a heat sink 10. The heat sink 10 is arranged between the flat tubes 24.

[0057] Combine Figure 6 and Figure 8As shown, a partition 25 is provided in the first water tank 21, which divides the interior of the first water tank 21 into a first liquid accommodating chamber 211 and a third liquid accommodating chamber 212. A second liquid accommodating chamber 221 is provided in the second water tank 22. One end of the flat tube 24 is connected to the first liquid accommodating chamber 211 or the third liquid accommodating chamber 212, and the other end of the flat tube 24 is connected to the second liquid accommodating chamber 221.

[0058] The first water tank 21 is provided with a first liquid hole 213 connected to the first liquid accommodating chamber 211, and the first liquid hole 213 is provided with a first liquid nozzle 214; the first water tank 21 is provided with a second liquid hole 215 connected to the third liquid accommodating chamber 212, and the second liquid hole 215 is provided with a second liquid nozzle 216; the first water tank 21 is also provided with a drainage hole 281 connected to the third liquid accommodating chamber 212, and the drainage hole 281 is provided with a drainage nozzle 282.

[0059] During use, the first water tank 21 and the second water tank 22 in the water-cooled radiator are filled with water or other coolant, and the coolant circulates through the first water tank 21 , the heat dissipation component 23 and the second water tank 22 .

[0060] Specifically, the coolant enters the first liquid chamber 211 through the first liquid nozzle 214, and the coolant in the first liquid chamber 211 flows to the second liquid chamber 221 through the connected flat tube 24. At this time, the heat sink 10 performs heat exchange on the coolant in the flat tube 24 and radiates the heat outward; then the coolant in the second liquid chamber 221 flows to the third liquid chamber 212 through the flat tube 24 connected thereto, and at this time, the heat sink 10 re-dissipates the heat for the coolant in the flat tube 24; the coolant flowing into the third liquid chamber 212 flows out from the second liquid nozzle 216 under the action of a driving mechanism such as a water pump, and is then discharged into the first liquid chamber 211 through the first liquid nozzle 214, forming a circulating flow.

[0061] During normal use, the drain nozzle 282 is in a closed state, blocking the drain hole 281 ; when liquid injection or drainage is required, the drain nozzle 282 can be opened to inject or discharge the coolant through the drain hole 281 .

[0062] Combine Figure 7 As shown, in this embodiment, heat sinks 10 are closely arranged between the two flat tubes 24. The heat sinks 10 absorb the heat of the coolant in the flat tubes 24 through heat conduction and dissipate the heat through airflow or the like.

[0063] Combine Figure 5 and Figure 6 As shown, the water-cooled radiator includes a first outer plate 26 and a second outer plate 27 . The first outer plate 26 and the second outer plate 27 are arranged opposite to each other and are respectively arranged on both sides of the heat dissipation component 23 .

[0064] The first outer plate 26 and the second outer plate 27 serve to fix and limit the heat dissipation assembly 23 , and cooperate with the first water tank 21 and the second water tank 22 to form a basket-shaped structure to accommodate and fix the heat dissipation assembly 23 inside.

[0065] In one embodiment, the first water tank 21 and the second water tank 22 are closed box structures with both ends sealed to accommodate the coolant.

[0066] In this embodiment, both ends of the first water tank 21 and the second water tank 22 are open. Blocking plates 28 are provided at both ends of the first outer plate 26 and the second outer plate 27. The shape of the blocking plates 28 matches the openings of the first water tank 21 or the second water tank 22. The first outer plate 26 and the second outer plate 27 respectively block the openings of the first water tank 21 and the second water tank 22 to form a closed box for containing coolant. Blocking the first water tank 21 and the second water tank 22 by the first outer plate 26 and the second outer plate 27 can improve the connection strength between the first outer plate 26 and the second outer plate 27 and the first water tank 21 and the second water tank 22, thereby improving the stability of the overall structure.

[0067] Combine Figure 6 As shown, in this embodiment, the water-cooled radiator further includes a first positioning plate 291 and a second positioning plate 292. The first positioning plate 291 is disposed between the first outer plate 26 and the heat dissipation assembly 23, and the second positioning plate 292 is disposed between the second outer plate 27 and the heat dissipation assembly 23. The provision of the first positioning plate 291 and the second positioning plate 292 allows the heat dissipation assembly 23 to be better positioned, thereby preventing the heat dissipation assembly 23 from loosening.

[0068] The above is a detailed introduction to the heat sink and water-cooled radiator provided by the implementation method of the present application, and specific examples are used to illustrate the principles and implementation methods of the present application. The above description is only used to help understand the method of the present application and its core mechanism; at the same time, for general technical personnel in this field, based on the ideas of the present application, there will be changes in the specific embodiments and application scope.
