AI Technical Summary

Technical Problem

Existing water-cooled radiators are prone to form thermal boundary layers in low flow velocity scenarios, resulting in a decrease in heat exchange efficiency; in high flow velocity scenarios, traditional fixed flow velocity structure will lead to excessive resistance to the runner, limiting the increase in flow velocity and causing high energy consumption problems.

Method used

A water-cooled radiator is designed, using turbulence components and transmission components. Through structures such as baffles, rotating shafts, torsion springs and transmission gears, a turbulence and active adjustment flow channel structure is formed to avoid the formation of a thermal boundary layer and optimize the water flow path.

Benefits of technology

In the low flow rate scenario, the turbulent flow component avoids the formation of thermal boundary layers and improves the heat exchange effect; in the high flow rate scenario, the transmission component adjusts the flow channel structure, reduces the resistance of the tributary to the mainstream, improves the flow rate and heat dissipation effect, and reduces energy consumption.

Description

Technical Field

[0001] The invention relates to the technical field of water cooling devices, and in particular to a water cooling radiator. Background Art

[0002] With the development of electronic technology, the performance of electronic equipment has improved rapidly, the power has increased rapidly, and the power dissipation of the entire system has also increased sharply, causing the heat of electronic components to become higher and higher. If the temperature of electronic components is too high, it will affect the performance and stability during operation. Therefore, in order to ensure that electronic components can operate normally, it is necessary to dissipate heat for electronic components.

[0003] Some special electronic components, such as display cards, CPUs, etc., require faster cooling, and water cooling has a better cooling effect than air cooling. The high specific heat of water enables it to absorb more heat. Under the same heat dissipation conditions, water cooling can keep the temperature of electronic components at a lower level, enhancing the stability and performance of electronic equipment. The water-cooled radiator has a water inlet and outlet, and there are multiple water channels inside the radiator, which can give full play to the advantages of water cooling and take away more heat.

[0004] A water cooling component for a high-power power supply disclosed in Chinese patent CN118159000A includes a cold head, a hot water pipe, a cold water pipe and a cold row. The cold row includes a left reference water cooling component, an additional water cooling component, a right reference water cooling component and a water cooling fan. The left reference water cooling component includes a main contact section pipe and a left reference frame. The additional water cooling component includes a secondary contact section pipe and an additional frame. The right reference water cooling component includes a connecting section pipe and a right reference frame. The left reference frame, the additional frame and the right reference frame are all provided with heat conducting strips. The additional frame and the right reference frame are all provided with multiple groups of water pipe fastening components. The main contact section pipe, the secondary contact section pipe and the junction section pipe are quickly fixed by the multiple groups of water pipe fastening components, and the water pipe fastening components in the same vertical column are driven by a group of driving components to perform opening and closing actions.

[0005] However, compared with the prior art and the comparative solution, it can be seen that the water cooling component still has the following problems during actual use:

[0006] In the process of water-cooled radiators dissipating heat for electronic components, a thermal boundary layer (thermal boundary layer, also known as temperature boundary layer. It refers to a thin layer of fluid characterized by a sharp change in thermal enthalpy formed near the wall of viscous fluid flow) will be formed in the flow channel of the water-cooled radiator. When the flow velocity is constant, the fluid in the flow channel is in a laminar state. The heat dissipation effect at the thermal boundary layer is mainly the heat conduction of the fluid in the laminar state. The fluid in the same flow channel is prone to form laminar stratification of different temperatures due to the different distances from the heating position of the electronic components. The heat exchange effect between the fluids in different stratifications is poor, which affects the heat dissipation effect. In low flow rate scenarios, the water flow is in a laminar state, and it is very easy to form a stable heat accumulation layer on the surface of the flow channel, which will cause a sharp drop in heat exchange efficiency and seriously affect the heat dissipation effect. In high flow rate scenarios, although high flow rate can enhance the heat dissipation capacity to a certain extent, the traditional fixed flow channel structure will lead to excessive flow channel resistance, which will cause a significant pressure drop, which will limit the further increase of flow rate and bring about a prominent high energy consumption problem.

[0046] The working process is as follows:

[0047] S1. When in use, the cold head 2 is installed at the heating position of the electronic component, and the water pump 105 is started. Water enters the housing 21 through the cooling pipe 103 and the first connecting pipe 3, and the water flows into the flow channel 233 from the diversion port 232. When the water flows through the rotating plate 234 and the baffle 213, the water flows into a main flow flowing along the rotating plate 234 and a branch flow flowing around the baffle 213;

[0048] S2. When the water pressure entering the housing 21 is relatively low, since the baffle 213 is rotatably connected to the housing 21 via the rotating shaft 214, and the torsion spring 215 is disposed between the rotating shaft 214 and the housing 21, when the water flows through the baffle 213, the water flows impact the baffle 213, causing the baffle 213 to swing back and forth under the impact of the water flow and the elastic action of the torsion spring 215, further causing the tributary to fluctuate, thereby preventing the formation of a thermal boundary layer in the tributary region;

[0049] S3, the mainstream is divided into branches when passing through the baffle 213, and the branches bypass the baffle 213 and merge into the mainstream again, impacting the mainstream area to form turbulence, thereby preventing the formation of a thermal boundary layer in the mainstream area (such as Figure 8 As shown), the heat exchange effect between water flows in the same flow channel 233 is improved, thereby improving the heat dissipation effect;

[0050] S4. When the water pressure entering the housing 21 is relatively high, the driving member 241 is started, the driving member 241 drives the first transmission gear 243 to rotate through the driving gear 242, and the first transmission gear 243 drives the rotating member 245 to rotate through the driven gear 244;

[0051] S5. Since the slide groove 246 is a wave-shaped annular groove, during the rotation of the rotating member 245, the slider 235 drives the rotating plate 234 to swing back and forth in the flow channel 233;

[0052] S6, when the rotating plate 234 swings in the flow channel 233, the rotating plates 234 at intervals move synchronously. When the rotating plate 234 rotates, a gap for water flow to pass through is formed between the rotating plate 234 and the connecting frame 231. The tributary area between the swinging rotating plate 234 and the connecting frame 231 becomes the mainstream area, reducing the resistance of the tributary to the mainstream, thereby increasing the flow rate of water through the flow channel 233 and ensuring the heat dissipation effect (such as Fig. 9 and Fig.10 shown);

[0053] S7. When the rotating plate 234 swings back and forth in the flow channel 233, it also disturbs the water flow nearby, thereby preventing the water flow in the flow channel from being stratified, improving the heat exchange effect between the water flows in the same flow channel 233, and thus improving the heat dissipation effect;

[0054] S8, after passing through the flow channel 233, the water flows out from the fourth connector 212 into the second connecting pipe 4, and then enters the cooling pipe 103 through the water pump 105 to form a circulation, and the fan 102 is started to cool the water flow in the cooling pipe 103 through the heat sink 104.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
