Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] like Figure 1-5 As shown in the figure, an embodiment of the present invention provides a computer CPU heat sink, including a water cooling component 1 and an air cooling component 2. The water cooling component 1 includes a pump box 11 and a water cooling box 12, which are connected by a pipeline. The air cooling component 2 includes at least two sets of heat sinks 21 and a main fan 22 disposed between the two sets of heat sinks 21. The pipeline connecting the pump box 11 and the water cooling box 12 is connected to the interior of the heat sinks 21.

[0031] like Figure 1-5 As shown, in some embodiments, one side of the main fan 22 extends to one side of the two sets of heat sinks 21 and is fixedly connected to the pump box 11, and the other side of the main fan 22 is attached to one side of the water cooling box 12.

[0032] One side of the main fan 22 is attached to one side of the water-cooled box 12. This design allows the water-cooled box 12 to dissipate heat from the main fan 22 at the same time, reducing the overheating failure that occurs when the main fan 22 is in high-frequency state.

[0033] like Figure 1-5 As shown, in some embodiments, the air-cooled assembly 2 further includes an auxiliary fan 23, wherein a bracket 24 is fixedly mounted on a set of heat sinks 21, and the auxiliary fan 23 is fixedly mounted on the heat sinks 21 through the bracket 24, and the auxiliary fan 23 is opposite to the air intake side of the main fan 22.

[0034] The auxiliary fan 23 accelerates the air intake of the main fan 22, improving the air intake efficiency of the main fan 22. At the same time, it can also work with the main fan 22 to dissipate heat from the two sets of heat sinks 21, further improving the overall heat dissipation efficiency of the computer CPU heat sink. The heat on the first circulation pipe 13 and the second circulation pipe 14 is transferred to the heat sink 21. The main fan 22 and the auxiliary fan 23 start to dissipate heat from the heat sink 21, the first circulation pipe 13 and the second circulation pipe 14.

[0035] like Figure 1-5 As shown, in some embodiments, the water-cooled box 12 includes a box front cover 121 and a box rear cover 122. A thermally conductive copper sheet 123 is provided on one side of the box front cover 121, and both sides of the thermally conductive copper sheet 123 are coated with thermally conductive silicone grease.

[0036] The front cover 121 and the rear cover 122 of the enclosure are secured with screws and a sealing gasket is installed in the middle. The water cooling box 12 is made of aluminum. Compared with the CPU directly contacting the water cooling box 12 through thermal grease, the thermally conductive copper sheet 123 can serve as a heat dissipation layer to alleviate the problem of local hot spots of the CPU, which is especially suitable for high power consumption or overclocking scenarios.

[0037] like Figure 1-5 As shown, in some embodiments, a heat-conducting copper plate 124 is provided inside the housing cover 121, and a plurality of sets of guide vanes 125 are provided inside the heat-conducting copper plate 124. Each set of guide vanes 125 includes at least two guide vanes 125 that are relatively inclined and staggered from each other.

[0038] The coolant entering the water-cooled box 12 flows from top to bottom. The water-cooled box 12 absorbs the heat from the CPU and conducts it to the heat-conducting copper plate 124. The multiple sets of cross-staggered and inclined guide vanes 125 inside the heat-conducting copper plate 124 can slow down the flow speed of the coolant, so that the coolant can fully contact the water-cooled box 12 and the heat-conducting copper plate 124 to remove heat and further improve heat dissipation efficiency.

[0039] like Figure 1-5As shown, in some embodiments, two heat-conducting plates 126 are symmetrically arranged on one side of the rear cover 122 of the housing. The end of the heat-conducting plate 126 away from the rear cover 122 passes between the two sets of heat sinks 21. A decorative plate 127 is provided on one side of the heat-conducting plate 126. A retaining plate 128 is provided at the top and bottom of the heat-conducting plate 126. One end of the retaining plate 128 is tapered. The end of the heat sink 21 facing the retaining plate 128 is provided with a notch 25 for engaging with the retaining plate 128.

[0040] The heat-conducting plate 126 can not only transfer heat to the heat sink 21, but also serve as a limiting component for the heat sink 21, achieving assembly consistency and stability of multiple heat sinks 21 in each group.

[0041] like Figure 1-5 As shown, in some embodiments, both ends of the heat sink 21 are provided with folded edges 26. One side of the folded edge 26 is provided with a groove 27, and the other side is provided with a protrusion 28 that matches the groove 27. The folded edges 26 of two adjacent heat sinks 21 are engaged together by the groove 27 and the protrusion 28.

[0042] The folded edge 26 of the heat sink 21 can create a gap between two adjacent heat sinks 21 to facilitate airflow. The groove 27 and protrusion 28 on the folded edge 26 can lock two adjacent heat sinks 21. When used with the card plate 128, it can limit the front and back and left and right positions of the heat sink 21 group, further ensuring the assembly stability of the heat sink 21.

[0043] like Figure 1-5 As shown, in some embodiments, the top and bottom of the pump box 11 are respectively provided with a plurality of circulation pipes 13 and circulation pipes 14. The ends of the circulation pipes 13 and 14 away from the pump box 11 pass through the two sets of heat sinks 21 and extend into the interior of the water-cooled box 12. A replenishment tank 15 is provided on one side of the pump box 11. A sealing plug 16 is provided on the top of the replenishment tank 15. A pump is provided inside the pump box 11. One end of each of the circulation pipes 13 is connected to the output end of the pump. One end of each of the circulation pipes 14 is connected to the input end of the pump through the replenishment tank 15.

[0044] Pump housing 11 is connected to coolant tank 15, and pump output is connected to coolant tank 15. When pump is started, pump input draws coolant and delivers it to the interior of circulation pipe 13. Circulation pipe 13 delivers coolant to the interior of water cooling box 12 to cool the CPU. Coolant flows to the bottom of water cooling box 12 and re-enters pump housing 11 and coolant tank 15 through circulation pipe 2 14, where it is drawn back by pump. During the process, main fan 22 and auxiliary fan 23 are started to dissipate heat from heat sink 21, circulation pipe 13, and circulation pipe 2 14. Coolant can be replenished or removed and replaced by unscrewing sealing plug 16.

[0045] In summary, efficient heat dissipation is achieved through the cooperation of water-cooling component 1 and air-cooling component 2. The water-cooling box 12 adopts an aluminum material combined with heat-conducting copper fins 123 and guide vanes 125, which not only improves the heat conduction efficiency of the CPU, but also optimizes the heat exchange process of the coolant. In addition, the water-cooling box 12 can also dissipate heat from the main fan 22, reducing failures caused by high heat. The air-cooling component 2 accelerates the airflow of the heat sink 21 through the linkage of the main fan 22 and the auxiliary fan 23. The heat-conducting plate 126 is designed to simultaneously undertake the functions of heat transfer and positioning of the heat sink 21, and the folded edge 26 snap-fit ​​structure ensures the stability of the component.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
