Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation plates, in particular to a high heat dissipation type uniform water cooling plate. Background Technique

[0002] A water cooling plate usually refers to a water cooling heat dissipation plate or a liquid cooling plate. It is a cooling device that uses water flow through the heat dissipation plate to achieve the purpose of heat dissipation. The water cooling plate usually consists of multiple flat plates, and these flat plates are connected by thin water channels. When the coolant enters from the inlet of the plate, passes through the flow channel, and then flows out from the outlet, it can take away the heat generated by the electronic components (such as CPU, graphics card, etc.) installed on the surface of the plate, so as to achieve the cooling effect.

[0003] There is a prior art balanced heat dissipation type water cooling plate, which includes a lower heat dissipation plate. An upper heat dissipation plate is provided above the lower heat dissipation plate. Heat dissipation fins are provided on the upper surface of the upper heat dissipation plate. A diversion groove is jointly opened on the upper surface of the lower heat dissipation plate and the lower surface of the upper heat dissipation plate. A diversion pipe is embedded in the interior of the diversion groove.

Sealing rings are embedded and installed on the lower heat dissipation plate at both ends of the diversion groove. Limit sleeves in an inverted "U" shape are sleeved on the upper surfaces at both ends of the diversion groove. The utility model is beneficial to avoid the phenomenon that the cooling water adsorbs more heat during the circulation in the water cooling plate, resulting in the reduction of the heat absorption effect when the cooling water flows to the water outlet of the water cooling plate, thereby being beneficial to reducing the temperature difference between the water inlet end and the water outlet end of the water cooling plate and realizing the balanced heat dissipation of the water cooling plate.

However, the utilization rate of the cooling water of this structure is relatively low, and the cooling water is wasted to a certain extent.

[0027] In the specific implementation process, as shown in FIG. Figures 1 - 7 Figures 1 - 7 a high heat dissipation type uniform water cooling plate includes an upper heat dissipation plate and a lower heat dissipation plate. An installation groove 1 is commonly formed on the opposite sides of the upper heat dissipation plate and the lower heat dissipation plate. A flow guiding component is arranged in the installation groove 1, and the upper heat dissipation plate is connected to the lower heat dissipation plate through a plurality of fixing members.

[0028] The flow guiding component includes a flow guiding pipe 2 and two T-shaped pipes 3. The flow guiding pipe 2 is located in the installation groove 1. One ends of the two T-shaped pipes 3 are respectively fixedly sleeved at both ends of the flow guiding pipe 2. A partition plate 4 is arranged inside the flow guiding pipe 2. Both ends of the partition plate 4 respectively extend into the two T-shaped pipes 3. Flow guiding grooves 5 are respectively formed on both sides of the partition plate 4 to increase the contact area between the partition plate 4 and the coolant, thereby improving the heat transfer efficiency of the coolant on both sides of the partition plate 4 and making the temperature of the coolant on both sides of the partition plate 4 more uniform. The part of the partition plate 4 located in the flow guiding pipe 2 is spirally arranged, so that the coolant flows along the spiral direction in the flow guiding pipe 2, and the coolant will continuously change its direction during the flowing process, and then the coolant can be continuously tumbled, so that the coolant can contact the inner wall of the flow guiding pipe 2 to a greater extent, and the efficiency of the coolant absorbing the heat on the flow guiding pipe 2 is increased.

[0029] The upper heat dissipation plate includes an upper fixing plate 6 and a plurality of upper heat dissipation fins 7. One sides of the plurality of upper heat dissipation fins 7 are fixedly connected to the side of the upper fixing plate 6 away from the flow guiding pipe 2. The lower heat dissipation plate includes a lower fixing plate 8 and a plurality of lower heat dissipation fins 9. One sides of the plurality of lower heat dissipation fins 9 are fixedly connected to the side of the lower fixing plate 8 away from the flow guiding pipe 2. The heat exchange efficiency between the water cooling plate and the outside can be increased through the upper heat dissipation fins 7 and the lower heat dissipation fins 9.

[0030] The outer surface of the T-tube 3 is provided with a plurality of convex rings 10 for increasing friction. When the pipe is sleeved on the T-tube 3 when the external circulating coolant is connected, the friction between the two is increased, so that the pipe is not easy to fall off, thereby avoiding leakage.

[0031] The fixing part includes a baffle 11, and a threaded column 12 is provided on one side of the baffle 11. The end of the threaded column 12 away from the baffle 11 movably penetrates the lower fixing plate 8 and the upper fixing plate 6 respectively. The end of the threaded column 12 away from the baffle 11 is threadedly sleeved with a nut 13, and one side of the nut 13 is fitted with one side of the upper fixing plate 6. Two lever blocks 14 are fixedly provided on the side of the nut 13 away from the upper fixing plate 6. The threaded column 12 is passed through the lower fixing plate 8 and the upper fixing plate 6 in turn and fixed by the nut 13. The two lever blocks 14 fixedly provided on the nut 13 are used to facilitate manual pulling, so that the nut 13 can be tightened without using tools.

[0032] A plurality of limit blocks 15 are provided on the top of the baffle 11, and a plurality of limit grooves matching the limit blocks 15 are provided on the bottom of the lower fixed plate 8. The baffle 11 is limited by inserting the limit blocks 15 into the limit grooves, thereby limiting the threaded column 12 to prevent the threaded column 12 from rotating with the nut 13 when the nut 13 is turned.

[0033] The four corners of the top of the lower fixing plate 8 are respectively provided with positioning columns 16, and the four corners of the bottom of the upper fixing plate 6 are respectively provided with positioning holes matching the positioning columns 16. By placing the guide tube 2 in the mounting groove 1 at the top of the lower fixing plate 8, and by buckling the upper fixing plate 6 on top of the lower fixing plate 8, the four positioning holes opened at the bottom of the upper fixing plate 6 are respectively aligned with the four positioning columns 16 set on the top of the lower fixing plate 8, and by inserting the positioning columns 16 into the positioning holes, the guide tube 2 is fixed between the upper fixing plate 6 and the lower fixing plate 8.

[0034] The working principle provided by the present utility model is as follows: Before use, place the diversion pipe 2 in the installation groove 1 at the top of the lower fixing plate 8, and buckle the upper fixing plate 6 above the lower fixing plate 8, so that the four positioning holes opened at the bottom of the upper fixing plate 6 are respectively aligned with the four positioning posts 16 arranged at the top of the lower fixing plate 8. Insert the positioning posts 16 into the positioning holes to fix the diversion pipe 2 between the upper fixing plate 6 and the lower fixing plate 8. Then, pass the threaded post 12 through the lower fixing plate 8 and the upper fixing plate 6 in sequence, and fix it with the nut 13 to complete the installation. During use, divide the interior of the diversion pipe 2 into two chambers by the partition plate 4. The coolant can flow into the diversion pipe 2 from both ends respectively through the water injection ends of the two T-shaped pipes 3 and flow relatively along the two chambers, and finally flow out from the water outlet ends of the two T-shaped pipes 3. In this way, it can avoid to a certain extent the phenomenon that the coolant absorbs too much heat during circulation in the water-cooling plate, resulting in the reduction of the heat absorption effect when the coolant flows to the water outlet of the water-cooling plate. Therefore, it is beneficial to reduce the temperature difference between the water inlet end and the water outlet end of the water-cooling plate. And the partition plate 4 located in the diversion pipe 2 is arranged in a spiral shape, so that the coolant flows in the diversion pipe 2 along the spiral direction, so that the coolant will continuously change its direction during the flow process, so that the coolant can keep tumbling, so that the coolant can contact the inner wall of the diversion pipe 2 to a greater extent. And diversion grooves 5 are respectively opened on both sides of the partition plate 4 to increase the contact area between the partition plate 4 and the coolant, so as to improve the heat transfer efficiency of the coolant on both sides of the partition plate 4, make the temperature of the coolant on both sides of the partition plate 4 more balanced, and thus make the temperature of the entire cold water plate more balanced.

[0036] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly.
