[0032] Example 1

[0033] An embodiment of the present invention provides an immersion liquid-cooled edge computing unit, such as Figure 1-Figure 4 As shown, it includes: a sealed shell 1, an electronic component 2 is arranged in the sealed shell 1, the sealed shell 1 is filled with coolant, the electronic component 2 is immersed in the coolant, and circulation components are symmetrically arranged on the left and right sides of the sealed shell 1. The circulation component includes a liquid outlet pipe 3, one end of the liquid outlet pipe 3 is connected to the inside of the sealed shell 1, a transfer cylinder 4 is arranged at the other end of the liquid outlet pipe 3, a filter tube 5 is arranged at the lower end of the transfer cylinder 4, the lower end of the filter tube 5 is connected to the upper end of the spiral tube 6, the lower end of the spiral tube 6 is connected to the input end of the circulation pump 7, the output end of the circulation pump 7 is connected to one end of the liquid inlet pipe 8, and the other end of the liquid inlet pipe 8 is connected to the inside of the sealed shell 1.

[0034] The working principle and beneficial effects of the above technical solution are as follows: a closed cavity is set in the sealed shell 1, the electronic component 2 is installed in the closed cavity, and the sealed shell 1 is filled with coolant. The coolant can be any one of fluorinated liquid, silicone oil, and mineral oil. The electronic component 2 is completely immersed in the coolant. When the edge computing unit is working, the circulating pump 7 is started. Under the action of the circulating pump 7, the coolant in the spiral tube 6 can be transported to the liquid inlet pipe 8 through the circulating pump 7, and flows into the sealed shell 1 through the liquid inlet pipe 8. At the same time, the coolant in the sealed shell 1 can flow into the transfer cylinder 4 through the liquid outlet pipe 3. The coolant flows back to the spiral tube 6 after passing through the filter tube 5, thereby realizing the circulation of the coolant. The coolant can take away the heat of the electronic component 2, so that the electronic component 2 is quickly cooled down. Moreover, when the coolant flows in the spiral tube 6, the spiral tube 6 increases the flow distance of the coolant. The heat in the coolant is transferred to the spiral tube 6, and the heat can be transferred to the external environment through the spiral tube 6. In the present invention, the electronic component 2 is arranged in the closed cavity of the sealed shell 1, so that dust cannot adhere to the surface of the electronic component 2, thereby extending the service life of the edge computing unit. The electronic component 2 is immersed in the coolant, and the circulating flow of the coolant can enable the electronic component 2 to quickly dissipate heat, thereby improving the heat dissipation efficiency.

[0035] Example 2

[0036] On the basis of the above-mentioned embodiment 1, Figure 1 As shown, the liquid outlet pipe 3 is located above the liquid inlet pipe 8.

[0037] The working principle and beneficial effects of the above technical solution are as follows: the liquid outlet pipe 3 is located above the liquid inlet pipe 8, and the coolant can naturally flow into the spiral tube 6 under the action of gravity, thereby reducing the power consumption of the circulation pump 7 and achieving an energy-saving effect.

[0038] Example 3

[0039] On the basis of embodiment 1 or 2, the sealed housing 1 is made of heat-conducting material.

[0040] The working principle and beneficial effects of the above technical solution are as follows: since the sealed shell 1 is made of heat-conducting material, the heat of the coolant can be quickly transferred to the sealed shell 1, and part of the heat can be transferred to the external environment through the sealed shell 1, thereby ensuring the heat dissipation effect.

[0041] Example 4

[0042] On the basis of any one of Examples 1-3, Figure 2 As shown, a protective cover 9 is provided outside the circulation assembly, and one side of the protective cover 9 is connected to the outer side wall of the sealing housing 1;

[0043] A plurality of ventilation holes 10 are arranged on the front and rear sides of the protective cover 9 .

[0044] The working principle and beneficial effects of the above technical solution are as follows: the protective cover 9 is arranged on the outside of the circulation component, and the circulation component can be protected by the protective cover 9 to prevent the circulation component from being hit by the outside, thereby extending the service life of the circulation component. A plurality of ventilation holes 10 are arranged on the front and rear side walls of the protective cover 9, so that the inside of the protective cover 9 is connected with the external environment, and the heat dissipation of the spiral tube 6 is accelerated through the circulation of external air.

[0045] Example 5

[0046] On the basis of Example 4, Figure 3 As shown, a plurality of heat-conducting components are arranged in the sealed housing 1, and the plurality of heat-conducting components are distributed at equal intervals;

[0047] The heat-conducting component includes a first heat dissipation plate 11 and a second heat dissipation plate 12. The front and rear sides of the first heat dissipation plate 11 are connected to the front and rear inner walls of the sealed shell 1. The front and rear sides of the second heat dissipation plate 12 are connected to the front and rear inner walls of the sealed shell 1. A flow channel is set between the first heat dissipation plate 11 and the second heat dissipation plate 12. A first gap is set between one end of the first heat dissipation plate 11 and the right inner wall of the sealed shell 1. The other end of the first heat dissipation plate 11 extends to the outside of the left side wall of the sealed shell 1. A second gap is set between one end of the second heat dissipation plate 12 and the left inner wall of the sealed shell 1. The other end of the second heat dissipation plate 12 extends to the outside of the right side wall of the sealed shell 1.

[0048] The working principle and beneficial effects of the above technical solution are as follows: a plurality of heat-conducting components are further arranged in the sealed housing 1, and the plurality of heat-conducting components are evenly spaced. The heat-conducting components include a first heat sink 11 and a second heat sink 12. The front and rear side walls of the first heat sink 11 and the second heat sink 12 are connected to the front and rear side inner walls of the sealed housing 1, thereby separating the interior of the sealed housing 1. A flow channel is arranged between the first heat sink 11 and the second heat sink 12. When the coolant enters the sealed housing 1 through the liquid inlet pipe 8, the coolant first flows along the lower surface of the first heat sink 11, enters the flow channel through the first gap, and then flows along the upper surface of the first heat sink 11 and The coolant flows on the lower surface of the second heat sink 12. When the coolant reaches the second gap, it flows to the next group of heat-conducting components through the second gap. The coolant flows in an S shape from bottom to top in the sealed housing 1. During the flow, it can fully contact the first heat sink 11 and the second heat sink 12. The first heat sink 11 and the second heat sink 12 absorb heat from the coolant. The first heat sink 11 and the second heat sink 12 are located at one end outside the sealed housing 1 and can transfer heat to the external environment. The heat in the first heat sink 11 and the second heat sink 12 is taken away by air flow, which further accelerates the cooling of the coolant and improves the heat dissipation efficiency.

[0049] Example 6

[0050] On the basis of Example 5, Figure 3 , Figure 4 As shown, a first rotating shaft 13 is arranged in the rotating cylinder 4, and the rear end of the first rotating shaft 13 is rotatably connected to the inner wall of the rear side of the rotating cylinder 4. A plurality of blades 14 are arranged on the outer wall of the first rotating shaft 13, and the plurality of blades 14 are distributed in a circular array about the central axis of the first rotating shaft 13. The front end of the first rotating shaft 13 extends to the outside of the rotating cylinder 4 and is provided with a plurality of first fan blades 15.

[0051] The working principle and beneficial effects of the above technical solution are as follows: when the coolant flows into the rotating drum 4 through the liquid outlet pipe 3, the rotating drum 4 is a horizontally arranged cylindrical body, and the coolant can impact the blades 14, thereby driving the first rotating shaft 13 to rotate. The rotation of the first rotating shaft 13 can drive the first fan blades 15 to rotate. The rotation of the first fan blades 15 can dissipate heat to the rotating drum 4, accelerate the cooling of the coolant, and improve the cooling effect of the coolant on the electronic components 2. A temperature sensor is arranged in the sealed shell 1, and the temperature sensor is electrically connected to the controller outside the sealed shell 1. The controller is electrically connected to the circulation pump 7. When the coolant temperature in the sealed shell 1 detected by the temperature sensor is higher than the preset temperature, the controller controls the circulation pump 7 to increase the speed, thereby accelerating the circulation of the coolant. The faster the circulation speed of the coolant can increase the speed of the first fan blades 15, thereby increasing the cooling air volume for the rotating drum 4, further improving the heat dissipation efficiency, and no additional driving equipment is required when the first fan blades 15 rotate, thereby reducing energy consumption and saving energy.

[0054] The working principle and beneficial effects of the above technical solution are as follows: when the first rotating shaft 13 rotates, it can drive the first sprocket 17 to rotate. The rotation of the first sprocket 17 can drive the second sprocket 19 to rotate through the chain 20. The rotation of the second sprocket 19 can drive the second rotating shaft 18 to rotate. When the second rotating shaft 18 rotates, it drives the mounting plate 21 to rotate. The second fan blades 22 on the outer periphery of the mounting plate 21 rotate, so that the external air enters the protective cover 9 at an accelerated speed and passes through the spiral tube 6, the first heat sink 11 and the second heat sink 12. The heat of the external leakage section of the spiral tube 6, the first heat sink 11 and the second heat sink 12 can be quickly taken away by the fast-flowing air, further accelerating the cooling of the coolant, improving the heat dissipation efficiency of the electronic components 2 in the edge computing unit, reducing the working energy consumption of the electronic components 2, improving the working performance of the electronic components 2, and extending the service life of the electronic components 2.

[0057] The working principle and beneficial effects of the above technical solution are as follows: the coolant will inevitably carry impurities during the circulation process. After the coolant flows into the filter tube 5 through the transfer cylinder 4, the filter screen 23 can filter the coolant passing through, thereby reducing the impurities inside the coolant. A liquid adding pipe is also provided on the side wall of the filter tube 5, and a liquid adding valve is provided on the liquid adding pipe.

[0062] The working principle and beneficial effects of the above technical solution are as follows: as the impurities on the surface of the filter 23 increase, the impurities will block the filter 23, the circulation speed of the coolant will slow down, and the heat dissipation efficiency will be reduced. Therefore, a de-impurity component is set on the filter 23. When the impurities on the surface of the filter 23 increase, the coolant will gradually accumulate in the filter tube 5 and the transfer cylinder 4, and part of the coolant will flow upward to the vertical pipe 40 through the connecting pipe 45. As the cooling fluid pressure gradually increases, the sliding plate 42 separates from the magnet 44 and slides upward along the inner wall of the vertical pipe 40 under the push of the high-pressure coolant. The sliding plate 42 drives the sliding rod 28 to slide in the direction close to the fixed block 31 through the pull rope 46.

When the sliding rod 28 slides toward the fixed block 31, the connecting spring 30 is compressed, and the sliding rod 28 drives the dust-removing plate 27 to slide along the upper surface of the filter screen 23. The dust-removing plate 27 slides toward the first connecting hole 25. At this time, impurities on the upper surface of the filter screen 23 are accumulated on the side of the dust-removing plate 27 close to the baffle 35. When the dust-removing plate 27 slides to the first connecting hole 25, the driving block 37 is gradually inserted into the driving groove 36. The lower position of the driving block 37 is first inserted into the upper position of the driving groove 36, and then as the dust-removing plate 27 slides, the inclined surface of the driving block 37 moves along the driving groove The inclined surface 36 slides, so that the upper end of the baffle 35 slides upward in the first sliding cavity 32, the first spring 34 is compressed, and the third connecting hole 39 in the baffle 35 is gradually connected with the second connecting hole 26. At this time, the coolant can flush the side of the impurity removal plate 27 close to the baffle 35 through the flushing hole 38 in the driving block 37, and the impurities accumulated on the side wall of the impurity removal plate 27 are flushed into the collection box 24, thereby improving the impurity removal effect. At this time, due to the dredging of the filter screen 23, the coolant can quickly pass through the filter screen 23, and the coolant accumulated in the filter tube 5 and the rotating cylinder 4 quickly flows into the spiral tube 6. Under the action of the second spring 43, the sliding plate 42 slides downward and is attracted by the magnet 44, and the coolant in the vertical tube 40 The liquid flows into the filter tube 5 through the connecting pipe 45. Under the action of the connecting spring 30, the slider 29 slides away from the fixed block 31, and the impurity removal plate 27 returns to its original position. Under the action of the first spring 34, the baffle 35 slides downward and returns to its original position, so that the baffle 35 blocks the second connecting hole 26 again, preventing the coolant from flowing into the collection box 24 through the first connecting hole 25, thereby reducing the loss of coolant. By setting up an impurity removal component, the upper surface of the filter screen 23 can be automatically cleaned, and there is no need to manually clean the filter screen 23, thereby extending the service life of the filter screen 23. At the same time, it can ensure the rapid circulation of the coolant and ensure the heat dissipation efficiency of the electronic components 2 in the edge computing unit.
