TECHNICAL FIELD

[0001] The utility model belongs to the technical field of data center, specifically relates to a data center liquid cooling device. BACKGROUND

[0002] In today's era of rapid development of digitization and informatization, the role of data centers is increasingly prominent. The processing chips inside the data center, as the core component, have continuously improved in speed and performance, but they are also accompanied by high heat problems. In order to ensure the stable operation and long service life of the processing chip, efficient cooling technology has become the key.

[0003] Traditional data center cooling methods mainly include air cooling and liquid cooling. Air cooling technology uses fans to blow air over the chips to dissipate heat, but as the power density of the chips continues to increase, air cooling technology gradually fails to meet the cooling needs, with relatively low cooling efficiency and being easily affected by environmental temperature and air flow.

[0004] Liquid cooling technology has received widespread attention due to its excellent heat dissipation performance. However, existing liquid cooling devices still have some significant problems in actual application.

[0005] In common liquid cooling systems, the cooling liquid usually enters the cooling chamber from an inlet. Due to the characteristics of the fluid, the cooling liquid tends to be unevenly distributed during the flow process. The area near the inlet tends to have more cooling liquid, while the area far from the inlet has relatively insufficient cooling liquid supply. This uneven distribution of cooling liquid leads to differences in cooling effect at different parts of the processing chip. Local cooling deficiency may cause the temperature of some areas of the chip to be too high, affecting its performance and reliability, and even shortening the service life of the chip.

[0006] In addition, relying solely on the natural flow of the cooling liquid, the heat exchange inside is not sufficient enough to quickly remove the heat generated by the processing chip. Moreover, in existing liquid cooling devices, the disturbance of the cooling liquid during the flow process is small, and the cooling liquid cannot be fully mixed, further limiting the improvement of the cooling effect.

[0007] Therefore, we propose a data center liquid cooling device that can actively and effectively uniformly stir and vibrate the cooling liquid, allowing the cooling liquid to fully and uniformly contact the processing chip, greatly improving the consistency and stability of the cooling effect, effectively extending the service life of the processing chip, and improving the operation efficiency and reliability of the data center. CONTENT OF THE UTILITY MODEL

[0008] The utility model provides a data center liquid cooling device, which can actively and effectively uniformly stir and vibrate the cooling liquid, so that the cooling liquid fully and uniformly contacts the processing chip, greatly improves the consistency and stability of the cooling effect, effectively prolongs the service life of the processing chip, and improves the operation efficiency and reliability of the data center.

[0009] The technical scheme adopted by the utility model is as follows:

[0010] A data center liquid cooling device comprises a placing shell, a processing chip is installed inside the placing shell, a space is left between the processing chip and the inner wall of the bottom of the placing shell, and three groups of stirring and vibrating assemblies are arranged inside the space.

[0011] Each stirring and vibrating assembly comprises a rotating assembly arranged on the inner wall of the bottom of the placing shell and a circular groove opened on the inside of the bottom of the placing shell, a rotating rod is arranged on the rotating assembly, four moving assemblies are arranged on the outer side of the rotating rod, each moving assembly is provided with a stirring vane, a connecting rod is arranged at the bottom of each stirring vane, a rolling pulley is arranged at the bottom of the connecting rod, the pulley is located inside the circular groove, and an arc-shaped block is arranged inside the circular groove.

[0012] Further, the placing shell is provided with a liquid inlet pipe and a liquid outlet pipe.

[0013] Further, the rotating assembly comprises a waterproof motor arranged on the inner wall of the bottom of the placing shell, and the output end of the waterproof motor is connected with the rotating rod.

[0014] Further, the moving assembly comprises a sliding groove opened on the outer side of the rotating rod, a fixed shaft is arranged inside the sliding groove, a sliding block is movably arranged on the fixed shaft, and one side of the sliding block is connected with the stirring vane.

[0015] Further, the sliding block is matched with the sliding groove.

[0016] Further, the arc-shaped block and the pulley are both provided with smooth surfaces.

[0017] The utility model achieves the following technical effects:

[0018] Firstly, the processing chip is installed inside the placing shell and starts to work. Then, the cooling liquid is injected into the placing shell from the specific inlet. Since the cooling liquid generally enters from one end, in the initial stage, the cooling liquid will gather near the inlet to form a local area with higher concentration, while the area far from the inlet has relatively less cooling liquid, which causes the obvious difference in the amount of cooling liquid contacted by different parts of the processing chip. At this critical moment, the rotating assembly is started. The driving motor in the rotating assembly starts to work, and drives the rotating rod to rotate at high speed through the transmission component. The rotation of the rotating rod drives the stirring fan blades outside the rotating rod to rotate. The stirring fan blades produce pushing and stirring effect on the cooling liquid in the rotating process. The continuous stirring of the fan blades makes the cooling liquid gathered near the inlet gradually spread to other areas, and the area originally with less cooling liquid starts to be supplemented, so that the initial uniform distribution of the cooling liquid in the placing shell is realized. At the same time, with the continuous rotation of the stirring fan blades, the connecting rod connected with the stirring fan blades is driven to rotate. The pulley at the bottom of the connecting rod moves in the circular groove. When the pulley rotates to the position of the arc-shaped block, the pulley is lifted up due to the block of the arc-shaped block which is higher than the bottom plane of the circular groove. The upward movement of the pulley drives the connecting rod to rise, and since the connecting rod is connected with the stirring fan blades, the stirring fan blades are driven to rise along the rotating rod through the moving assembly. After passing through the arc-shaped block, the stirring fan blades will descend again under the action of gravity and the pressure of the cooling liquid. In the process of rising and falling of the stirring fan blades, additional impact and disturbance are generated on the cooling liquid. When rising, the fan blades push the surrounding cooling liquid upward; when falling, the fan blades impact and extrude the cooling liquid below. The frequent vibration of the stirring fan blades further enhances the flow and mixing effect of the cooling liquid, so that the temperature distribution in the cooling liquid is more uniform, and the local temperature difference is reduced. The uniform distribution of the cooling liquid is maximized, and the cooling efficiency and quality of the processing chip are improved. BRIEF DESCRIPTION OF DRAWINGS

It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope specifically requested by the utility model.

[0027] As Figures 1-5 indicated, the technical scheme adopted by the utility model is specifically as follows: a data center liquid cooling device, comprising a placing shell 1, the placing shell 1 is internally provided with a processing chip 2, a space is left between the processing chip 2 and the inner wall of the bottom of the placing shell 1, and three stirring and vibrating assemblies are arranged in the space;

[0028] Each stirring and vibrating assembly comprises a rotating assembly arranged on the inner wall of the bottom of the placing shell 1 and a circular groove 3 opened on the inside of the bottom of the placing shell 1, a rotating rod 4 is arranged on the rotating assembly, four moving assemblies are arranged on the outer side of the rotating rod 4, each moving assembly is provided with a stirring fan blade 5, a connecting rod 6 is arranged at the bottom of each stirring fan blade 5, a pulley 7 that rolls is arranged at the bottom of the connecting plate, the pulley 7 is located in the circular groove 3, and an arc block 8 is arranged in the circular groove 3.

[0029] Among them, the placing shell 1 is provided with a liquid inlet pipe 9 and a liquid outlet pipe 10, the liquid inlet pipe 9 is located at the bottom of the placing shell 1, and the stirring and vibrating assembly can directly act on the cooling liquid when the cooling liquid is set in this way.

[0030] Meanwhile, the rotating assembly comprises a waterproof motor 11 arranged on the inner wall of the bottom of the placing shell 1, and the output end of the waterproof motor 11 is connected with the rotating rod 4.

[0031] The model of the waterproof motor 11 is PTM waterproof motor 11, which can achieve the effect of waterproofing and can work in harsh environments, and belongs to the prior art, which will not be described in detail here.

[0032] The moving assembly comprises a sliding groove 12 opened on the outer side of the rotating rod 4, a fixed shaft 13 is arranged in the sliding groove 12, a sliding block 14 is movably sleeved on the fixed shaft 13, and one side of the sliding block 14 is connected with the stirring fan blade 5. When the stirring fan blade 5 rises, the sliding block 14 rises on the fixed shaft 13, thereby generating vibration.

[0033] The sliding block 14 is matched with the sliding groove 12, so that the sliding block 14 can move smoothly in the sliding groove 12 without jamming.

[0034] The arc-shaped block 8 and the pulley 7 are provided with smooth surfaces, so that the friction is reduced, and the effect is improved.

[0035] The stirring fan blade 5 has a certain angle, so that the cooling liquid is better distributed, and belongs to the prior art, which will not be described in detail here.

[0036] The working principle of the utility model is as follows: firstly, the processing chip 2 is installed in the placing shell 1 and starts to work. Then, the cooling liquid is injected into the placing shell 1 from a specific inlet. Since the cooling liquid usually enters from one end, in the initial stage, the cooling liquid will gather near the inlet to form a local area with a relatively high concentration, and the area far from the inlet has relatively less cooling liquid, so that the amount of cooling liquid contacted by different parts of the processing chip 2 is obviously different. At this critical moment, the rotating assembly is started. The driving motor in the rotating assembly starts to work, and drives the rotating rod 4 to rotate at high speed through the transmission part. The rotating rod 4 rotates and drives the stirring fan blade 5 on the outer side to rotate. The stirring fan blade 5 produces a pushing and stirring effect on the cooling liquid in the rotating process. The continuous stirring of the fan blade makes the cooling liquid gathered near the inlet gradually spread to other areas, and the area originally with less cooling liquid starts to be supplemented, so that the initial uniform distribution of the cooling liquid in the placing shell 1 is realized. At the same time, with the continuous rotation of the stirring fan blade 5, the connecting rod 6 connected with the fan blade is driven. The pulley 7 at the bottom of the connecting rod 6 moves in the circular groove 3. When the pulley 7 rotates to the position of the arc-shaped block 8, the pulley 7 is lifted up due to the block of the arc-shaped block 8 which is higher than the bottom plane of the circular groove 3. The upward movement of the pulley 7 drives the connecting rod 6 to rise, and since the connecting rod 6 is connected with the stirring fan blade 5, the stirring fan blade 5 is driven to rise along the rotating rod 4 through the moving assembly. After passing the arc-shaped block 8, the stirring fan blade 5 is lowered again under the action of its own gravity and the pressure of the cooling liquid. In the process of rising and falling of the stirring fan blade 5, additional impact and disturbance are generated on the cooling liquid. When rising, the fan blade pushes the surrounding cooling liquid upward; when falling, the fan blade impacts and extrudes the cooling liquid below. The frequent vibration of the fan blade further enhances the flow and mixing effect of the cooling liquid, so that the temperature distribution in the cooling liquid is more uniform, and the local temperature difference is reduced. The uniform distribution of the cooling liquid is maximized, and the cooling efficiency and quality of the processing chip 2 are comprehensively improved.

[0037] The above only is the preferred embodiment of the utility model, it should be pointed out, for ordinary skilled person in the art, without departing from the principle of the utility model, can make a number of improvements and refinements, these improvements and refinements also should be considered the protection scope of the utility model.The structure, device and operating method not specifically described and explained in the utility model, are implemented according to conventional means in the art, unless specifically described and limited.
