Description

An embedded water-cooled heat sink Technical Field

[0001] This utility model relates to the field of physics, and in particular to heat dissipation technology, especially an embedded water-cooled radiator. Background Technology

[0002] With the continuous increase in the power of electronic devices, heat dissipation has become an increasingly prominent issue. In existing technologies, water-cooled radiators typically use welding or bonding processes to combine the water-cooling pipes with the heat dissipation base plate. However, during use, the water-cooling pipes and the heat dissipation base plate are not securely fixed and are prone to loosening, resulting in unsatisfactory heat dissipation performance. Summary of the Invention

[0003] The purpose of this utility model is to provide an embedded water-cooled heat sink, which solves the technical problems in the prior art such as unreliable fixing of water-cooling pipes to heat sink base plates, easy loosening, and unsatisfactory heat dissipation effect.

[0004] This utility model discloses an embedded water-cooled radiator, comprising a heat dissipation base plate and a U-shaped water-cooling tube. Two press-fit structural members are spaced apart on the upper surface of the heat dissipation base plate, each including two side wings. The side wings are integrally formed with the heat dissipation base plate, and are arranged parallel to each other, with their length direction parallel to the length direction of the heat dissipation base plate. An arc-shaped groove is provided in the heat dissipation base plate between the two side wings, with the lowest point of the inner wall of the arc-shaped groove located below the upper surface of the heat dissipation base plate. The U-shaped water-cooling tube includes two straight tubes and one bent tube. The two ends of the bent tube are connected to the two straight tubes respectively. The two straight tubes are located in the two arc-shaped grooves respectively. The two side wings bend towards each other and press and hold the straight tubes tightly. At least two press-fit recesses are spaced apart along the length direction on the upper surface of the straight tube, and any one of the press-fit recesses penetrates the side wing and the straight tube horizontally.

[0005] Furthermore, the vertical distance between the lowest point of the inner wall of the arc-shaped groove and the upper surface of the heat dissipation base plate is greater than or equal to 2mm.

[0006] Compared with existing technologies, the advantages of this invention are positive and significant. This invention uses a heat dissipation base plate and a U-shaped water-cooling pipe, riveted together to form an embedded water-cooled radiator. The high fit between the U-shaped water-cooling pipe and the heat dissipation base plate greatly improves heat dissipation capacity. The manufacturing process is simple and it has a wide range of applications. The lowest point of the inner wall of the arc-shaped groove is located below the upper surface of the heat dissipation base plate, which increases the contact area between the U-shaped water-cooling pipe and the heat dissipation base plate, increasing heat dissipation capacity and improving the radiator's heat dissipation effect.

[0012] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0013] As shown in Figures 1-5, an embedded water-cooled radiator of this utility model includes a heat dissipation base plate 1 and a U-shaped water-cooling pipe. Two press-fit structural members are spaced apart on the upper surface of the heat dissipation base plate 1. Each of the two press-fit structural members includes two side wings 2. The side wings 2 are integrally formed with the heat dissipation base plate 1. The two side wings 2 are arranged in parallel, and the length direction of the side wings 2 is parallel to the length direction of the heat dissipation base plate 1. An arc-shaped groove 3 is provided in the heat dissipation base plate 1 between the two side wings 2. The lowest point of the inner wall of the arc-shaped groove 3 is located below the upper surface of the heat dissipation base plate 1. The U-shaped water-cooling pipe includes two straight pipes 4 and a bent pipe 5. The two ends of the bent pipe 5 are respectively connected to the two straight pipes 4. The two straight pipes 4 are respectively located in the two arc-shaped grooves 3. The two side wings 2 bend towards each other and squeeze and hug the straight pipes 4. At least two press-fit recesses 6 are spaced apart along the length direction on the upper surface of the straight pipe 4. Any press-fit recess 6 penetrates the side wing 2 and the straight pipe 4 in the horizontal direction.

[0014] Furthermore, the vertical distance between the lowest point of the inner wall of the arc-shaped groove 3 and the upper surface of the heat dissipation base plate 1 is greater than or equal to 2mm.

[0015] The side wing 2 and the heat dissipation base plate 1 are integrally formed by extrusion. The riveting process is as follows: As shown in Figures 4 and 5, the two straight tubes 4 of the U-shaped water-cooling pipe are respectively placed into the two arc-shaped grooves 3. The mold 7 presses down on the side wing 2, causing the side wing 2 to deform and tightly grip the straight tube 4. The protrusions 8 on the mold 7 extrude riveting recesses 6 downwards on the side wing 2 and the straight tube 4, which can improve the fit between the straight tube 4 and the side wing 2.

[0016] This utility model uses a heat dissipation base plate 1 and a U-shaped water-cooling pipe to be press-fitted together to form an embedded water-cooled radiator. The U-shaped water-cooling pipe and the heat dissipation base plate 1 have a high degree of fit, which greatly improves the heat dissipation capacity. The manufacturing process is simple and has a wide range of applications. The lowest point of the inner wall of the arc-shaped groove 3 is located below the upper surface of the heat dissipation base plate 1, which can increase the contact area between the U-shaped water-cooling pipe and the heat dissipation base plate 1, increase the heat dissipation capacity, and improve the heat dissipation effect of the radiator.

[0017] An experiment was conducted on an embodiment where the vertical distance between the lowest point of the inner wall of the arc-shaped groove 3 and the upper surface of the heat dissipation base plate 1 is equal to 2 mm. The experimental data analysis parameters are shown in the table below:
