Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a radiator pinfin structure. Background Technique

[0002] With the rapid development of electronic technology and integration, the power density of electronic devices has been continuously increasing, which leads to a large amount of heat generated during the operation of electronic devices. If this heat cannot be effectively removed from the devices, it will affect the performance of the devices and even cause damage to the components. Therefore, the role of radiators becomes particularly important.

[0003] In the existing radiators, Pinfin can effectively increase the contact area between the fluid and the radiator, thereby accelerating the heat transfer speed. In the direct water-cooled structure radiator, Pinfin is usually cylindrical with a circular cross-section. The advantage of this design is that it can increase the heat dissipation area to a certain extent, thereby improving the cooling effect. However, this circular cross-section design also has certain disadvantages. One of the main problems is that there will be a large flow separation phenomenon on the leeward side. When the fluid flows through the Pinfin, a low-pressure area will be formed on the leeward side of the Pinfin, resulting in the obstruction of fluid flow and further reducing the cooling effect. Even if the circular pinfin is modified to an elliptical or water-drop shape to improve its disadvantages, there is still a flow separation phenomenon, which affects the cooling effect to a certain extent and needs to be optimized and improved. Content of the Utility Model

[0032] A connection and flow splitting component 5, the connection and flow splitting component 5 is threadedly connected to the inner bottom end of the top protection component 4, and a jack 6 is opened in the inner bottom wall of the heat dissipation connection frame 1;

[0033] In this embodiment: By arranging multiple groups of connection and flow splitting components 5 inside the frame where the heat dissipation connection frame 1 and the top protection component 4 are connected, the heat dissipation area is increased through the setting of two semi-ellipses, the flow separation phenomenon is slowed down, and the cooling effect is improved. The sliding clamping between the sliding clamping component 3 and the top protection component 4, and the positioning threaded connection between the connection and flow splitting component 5 and the top protection component 4 and the jack 6 are convenient for disassembly, facilitate the disassembly and replacement of individual parts of the device, and improve the use efficiency.

[0034] Specifically, as Figure 3 shown, the sliding clamping component 3 includes a sliding clamping strip 301, and the sliding clamping strip 301 is fixedly connected to the tops of the left and right walls of the heat dissipation connection frame 1. A fastening screw 302 is threadedly connected inside the sliding clamping strip 301;

[0035] In this embodiment: The cross-section of the sliding clamping strip 301 is T-shaped, which is convenient for clamping the top protection component 4 at the top. After being clamped to the appropriate position, it can be fixedly connected through the fastening screw 302.

[0036] Specifically, as Figure 3 shown, the top protection component 4 includes a top protection plate 401, and the top protection plate 401 is clamped to the top of the sliding clamping strip 301. Clamping grooves 402 are opened at both left and right ends inside the top protection plate 401, and threaded connection holes 403 penetrate through the middle parts of the upper and lower walls of the top protection plate 401;

[0037] In this embodiment: The top protection plate 401 is at the top for protection. It is connected through the clamping and fixing of the clamping grooves 402 and the sliding clamping strip 301, which is convenient for improving the convenience and stability of fixing. The threaded connection holes 403 facilitate the connection and fixing of the connection and diversion component 5.

[0038] Specifically, as Figure 4 shown, the connection and diversion component 5 includes a docking screw 501, and the docking screw 501 is threadedly connected inside the top protection plate 401. A buffer pad 503 is sleeved at the bottom end of the outer side of the docking screw 501, and a fastening nut 504 is threadedly connected to the top end of the outer side of the docking screw 501;

[0039] In this embodiment: The docking screw 501 is connected inside the threaded connection hole 403, then the mounting plate 502 is closely attached to the bottom wall of the top protection plate 401, and the top end is screwed by the fastening nut 504 to lock the connection and diversion component 5.

[0040] Specifically, as Figure 4 shown, the bottom end of the docking screw 501 is fixedly connected to a mounting plate 502, and a semi-elliptical cylinder 505 is rotatably connected to the bottom end of the mounting plate 502. Rotating adjustment rods 506 are welded to both the upper and lower ends of the semi-elliptical cylinder 505;

[0041] In this embodiment: A bottom end of the docking screw 501 is fixedly installed with a mounting plate 502. A semi-elliptical cylinder 505 is arranged at the bottom end of the mounting plate 502. The semi-elliptical cylinder 505 is obtained by cutting an elliptical cylinder in half. There is a gap between the two separated individual spaces. When the coolant flows, it can increase the contact area with the coolant. Also, multiple semi-elliptical cylinders 505 can form a pin-fin-like heat dissipation structure. The separated semi-elliptical cylinders 505 mitigate the influence brought by the flow separation phenomenon. The rotation adjustment rod 506 is docked and positioned with the jack 6. And the rotation adjustment rod 506 connected to the semi-elliptical cylinder 505 up and down is inserted into the inside of the mounting plate 502 and the jack 6 respectively at its upper and lower ends, and is tightened by screwing the fastening nut 504 at the top end. When the fastening nut 504 is loosened, the semi-elliptical cylinder 505 can be toggled for angle adjustment, and after adjustment, the fastening nut 504 is screwed again for fastening.

[0042] Specifically, as Figure 2 shown, the installation component 7 includes a welding block 701. The welding block 701 is fixedly connected to the bottom end of the heat dissipation connection frame 1, and a perforated mounting plate 702 is fixedly connected to the bottom end of the welding block 701;

[0044] The specific solution of this scheme is as follows: First, the welding block 701 is fixedly connected to the bottom end of the heat dissipation connection frame 1. The perforated mounting plate 702 connected to the bottom end can be fixed by connecting screws, which can fix the overall heat dissipation device. Then, the cross-section of the sliding clamping strip 301 is T-shaped, which is convenient for clamping the top protection plate 401 at the top. After being clamped to the appropriate position, it can be fixedly connected by the fastening screw 302. The top protection plate 401 is at the top for protection. It is connected through the clamping of the clamping groove 402 and the sliding clamping strip 301, which is convenient for improving the convenience and stability of fixation. The threaded connection hole 403 is convenient for connecting and fixing the connection shunt component 5. The docking screw 501 is connected to the inside of the threaded connection hole 403. Then, the mounting plate 502 is closely attached to the bottom wall of the top protection plate 401. The top is tightened by screwing the fastening nut 504 to lock the connection shunt component 5.

The rotation adjustment rod 506 is docked and positioned with the jack 6, and the rotation adjustment rods 506 connected to the upper and lower parts of the semi-elliptical cylinder 505 are respectively inserted into the inside of the mounting plate 502 and the jack 6, and are tightened under the screwing of the fastening nut 504 at the top end. When the fastening nut 504 is loose, the semi-elliptical cylinder 505 can be toggled for angle adjustment. After adjustment, continue to use the fastening nut 504 to screw and tighten for further adaptation adjustment to improve the cooling effect.
