DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Cooling box 2 is connected in series with heat-absorbing pipe 11 via a circulating cooling assembly. This allows cold water within cooling box 2 to flow through heat-absorbing pipe 11, thereby cooling the air within cooling compartment 4. Cooling compartment 4 communicates with the interior of data center main body 1 via air outlet 10. This allows the circulation of cold water within heat-absorbing pipe 11 to dissipate heat from data center main body 1, ensuring effective heat dissipation while reducing energy consumption to a certain extent. The cooling box 2 exchanges heat with the soil, maintaining a low water temperature within cooling box 2 through natural cooling.

[0027] The blower assembly within the air inlet 5 blows cold air from the outside into the cooling compartment 4, where it flows into the data center main body 1 through the air outlet 10 and is then discharged from the exhaust vent of the data center main body 1, accelerating air circulation. Furthermore, the heat absorption pipe 11 located between the air inlet 5 and the air outlet 10 further reduces the temperature of the air entering the data center main body 1, achieving efficient heat dissipation and resolving the low heat dissipation efficiency problem in the prior art.

[0028] The present invention provides three different cooling modes for the data center main body 1 through circulating water cooling, air cooling, and a combination of circulating water cooling and air cooling. This allows for flexible selection of the appropriate cooling mode based on the varying heat generation conditions within the data center main body 1, resolving the problem of a single cooling mode in the prior art. The present invention does not require use with precision air conditioning, and the energy consumption of the blower assembly and circulating cooling assembly is lower than that of precision air conditioning, effectively controlling energy consumption and achieving a more environmentally friendly use.

The deep cannula 21 is used to divert the water in the cooling box 2 downward to a deeper soil layer, and utilize the temperature of the soil to maintain a lower water temperature in the cooling box 2, further reducing energy consumption.

[0031] Preferably, the water drawing pipe 22 can be a PVC pipe or a metal pipe. The diameter of the water drawing pipe 22 is smaller than the inner diameter of the deep cannula 21. It is used to supply the water at the deepest bottom of the deep cannula 21, that is, the water with the lowest temperature, to the circulating cooling component to achieve the best water cooling and heat dissipation effect.

[0032] The second connector 25 and the third connector 28 can be water pipe sealing connectors in the prior art, and their specifications can be selected according to the adaptability of the water pipes to be connected.

[0033] Please see the attached Figure 2 Heat absorbing pipes 11 are evenly distributed in the cooling interlayers 4 on both sides of the data room main body 1. One end of the two groups of heat absorbing pipes 11 are connected through a connecting pipe 12, and the other ends of the two groups of heat absorbing pipes 11 are also connected through a connecting pipe 12; both connecting pipes 12 are provided with a sealed connector 13, one end of the circulating cooling component is connected to one of the connecting pipes 12 through the sealed connector 13, and the other end of the circulating cooling component is connected to the other connecting pipe 12 through the sealed connector 13.

[0034] Select a large wall in the data center's main body 1, typically one on each side, without doors or windows. Heat-absorbing pipes 11 are placed inside these walls to maximize the circulating water cooling effect and improve heat dissipation efficiency. The heat-absorbing pipes 11 on either side are connected by two connecting pipes 12 to form a single unit, facilitating connection to the cooling box 2 in series via the circulating cooling assembly.

[0035] Preferably, the sealing connector 13 can adopt the three-way connector of the existing technology, the two ends of the three-way connector are connected and installed on the connecting pipe 12, and the third end of the three-way connector is connected to the circulating cooling component to ensure that the water circulation is smooth and there is no leakage.

[0036] Please see the attached Figure 1 To the attached Figure 4The circulating cooling assembly includes a transfer tube 14, a liquid pump 17, a first conduit 26, a second conduit 30 and a third conduit 31; the liquid pump 17 is installed on the outer wall of the data room body 1 through a mounting base 16; one end of the two transfer tubes 14 is respectively connected to the sealing connectors 13 on the two connecting pipes 12, the other end of one of the transfer tubes 14 is connected to the liquid outlet end of the liquid pump 17 through the first connector 15, and the liquid inlet end of the liquid pump 17 is connected to the upper end of the water drawing pipe 22 through the first conduit 26 and the second connector 25; the other end of the other transfer tube 14 is connected to one end of the second conduit 30 through the fourth connector 29, and the other end of the second conduit 30 is connected to the water inlet 27 through the third connector 28.

[0037] Preferably, the liquid pump 17 can adopt a small water pump of the existing technology, and the specifications and models of the liquid pump 17 can be adaptively selected according to the pumping requirements of the cold water. The energy consumption of a small water pump is relatively lower than that of equipment such as precision air conditioners, which can reduce the energy consumption of the device.

[0038] A circulating cooling water circuit is formed by connecting the adapter tube 14, the first conduit 26, the second conduit 30, and the third conduit 31 in series at both ends of the heat absorbing tube 11. The first connector 15, the second connector 25, and the third connector 28 can be conventional water pipe sealing connectors, and their specifications can be selected based on the adaptability of the water pipes to be connected.

[0039] Please see the attached Figure 3 A plurality of first heat-conducting blocks 20 are provided on the inner wall of the cooling box 2 at circumferential intervals. One end of the first heat-conducting block 20 is located inside the cooling box 2, and the other end of the first heat-conducting block 20 extends to the outside of the cooling box 2 and is inserted into the soil layer.

[0040] Preferably, the first heat conducting block 20 can be made of metal materials with good thermal conductivity such as copper sheets and steel sheets, which can conduct the heat of the water in the cooling box 2 outward to the soil layer, thereby reducing the water temperature in the cooling box 2 to ensure the circulating water cooling effect.

[0041] Please see the attached Figure 3 A second heat-conducting block 23 is provided in the deep cannula 21. The second heat-conducting block 23 has a spiral structure and extends from the top to the bottom of the deep cannula 21. One end of the second heat-conducting block 23 is located in the deep cannula 21 and contacts the outer wall of the water-drawing pipe 22. The other end of the second heat-conducting block 23 extends to the outside of the deep cannula 21 and is inserted into the soil layer.

[0042] Preferably, the second heat-conducting block 23 can be made of metal materials with good thermal conductivity such as copper sheets and steel sheets, which can conduct the heat of the water in the deep tube 21 outward to the soil layer, thereby reducing the water temperature in the deep tube 21 and the cooling box 2, and further improving the circulating water cooling effect.

[0043] When setting the first heat-conducting block 20 and the second heat-conducting block 23, the sealing of the connection between the first heat-conducting block 20 and the cooling box 2 and the sealing of the connection between the second heat-conducting block 23 and the deep insertion tube 21 should be ensured. Preferably, they can be connected into an integral structure by one-piece molding and full welding to prevent water leakage.

[0044] Please see the attached Figure 3 The water-drawing pipe 22 is coaxially arranged with the deep cannula 21 , and the cavity between the water-drawing pipe 22 and the deep cannula 21 forms a spiral guide groove 24 through the second heat-conducting block 23 , and the lower end of the water-drawing pipe 22 is located at the bottom of the spiral guide groove 24 .

[0045] The water in the cooling box 2 flows through the spiral guide groove 24 to the bottom of the deep insert 21. Its spiral flow path is large and can fully contact the second heat-conducting block 23 and the wall of the water-drawing pipe 22, thereby conducting the heat in the water outward to the soil layer through the second heat-conducting block 23 and the wall of the water-drawing pipe 22.

[0046] Please see the attached Figure 3 A filling port 18 is provided on the top of the cooling box 2 , and a protective cover 19 is detachably provided on the filling port 18 .

[0047] The filling port 18 is used to inject cold water into the cooling box 2, and is also convenient for replacing the water in the cooling box 2. Preferably, a cover can be set on the top of the filling port 18 of the cooling box 2 when the cooling box 2 is buried to prevent soil from covering the filling port 18 and affecting the use of the filling port 18.

[0048] Preferably, the protective cover 19 can be a threaded screw-on cover, which is convenient and quick to assemble and disassemble, and has good sealing performance, and is used to prevent mud and sewage from flowing into the filling port 18.

[0049] Please see the attached Figure 4 The blowing assembly includes a bellows 6, a fixing frame 7, a motor 8 and a fan blade 9; the bellows 6 is matched and embedded in the air inlet 5, the motor 8 is installed in the bellows 6 through the fixing frame 7, and the fan blade 9 is installed on the output shaft of the motor 8, so that the air flows through the air inlet 5 under the rotation of the fan blade 9.

[0050] Motor 8 can be a small motor based on existing technology, driving fan blades 9. The rotating fan blades blow cold air from outside into cooling compartment 4. After heat exchange and cooling in heat absorption pipe 11, the air enters data center main body 1 through air outlet 10, achieving ventilation and heat dissipation. The specifications and power of motor 8 can be adaptively selected based on actual usage requirements. Motor 8 has lower energy consumption than existing precision air conditioners.

[0051] Please see the attached Figure 1 To the attached Figure 4 , the use method and working principle of the present invention are:

[0052] Cold water is injected into the cooling box 2 through the filling port 18, and the liquid pump 17 is started to suck the water in the water drawing pipe 22, and the water at the bottom of the deep insert tube 21 is sucked through the water drawing pipe 22. At this time, as the water at the bottom of the deep insert tube 21 is drawn out, the water in the cooling box 2 flows along the spiral guide groove 24 along a spiral path to the bottom of the deep insert tube 21. In this process, the heat in the water is discharged to the external soil layer through the second heat conducting block 23, so that the heat in the water is absorbed by the soil layer.

[0053] Low-temperature water flows through the water intake pipe 22 into the first conduit 26. Then, driven by the liquid pump 17, it flows along the third conduit 31 into the transfer pipe 14. It then flows along the connecting pipe 12 into the heat absorption pipe 11. The low-temperature water in the heat absorption pipe 11 absorbs heat from the air in the cooling compartment 4, generating low-temperature air. The low-temperature air in the cooling compartment 4 exchanges heat with the warmer air inside the data center main body 1 through the air outlet 10, achieving heat dissipation.

[0054] After heat exchange, the water temperature in the heat absorbing tube 11 rises and flows back into the cooling box 2 through the connecting tube 12, the transfer tube 14, and the second conduit 30 via the water inlet 27. The heat in the water in the cooling box 2 is conducted away from the external soil layer via the first heat conducting block 20 and the cooling box wall, naturally cooling the water in the cooling box 2. This eliminates the need for precision air conditioning and reduces energy consumption.

[0055] When the temperature inside data room main body 1 is high, motor 8 can be activated to rotate fan blades 9, drawing cool air from outside into data room main body 1 through air inlet 5 and air outlet 10. As air flows through air inlet 5 and air outlet 10, it is cooled by heat-absorbing pipe 11, improving ventilation and heat dissipation. After heat exchange within data room main body 1, the cool air is discharged through the exhaust vents within data room main body 1, accelerating air circulation and enhancing heat dissipation.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
