DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following is a brief introduction to the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0023] Please see Figure 1 The overall water circulation low-carbon consumption data center system includes the computer room 10 and the cabinet 20. The computer room 10 includes the cabinet placement layer 110 and the heat release layer 120. The cabinet placement layer 110 includes the wall 111. The wall 111 is provided with the water circulation pipe network 112. The water circulation pipe network 112 is provided with the first water supply pipe 115 and the first water outlet pipe 116 for providing cooling water to the cabinet 20.

[0024] The heat release layer 120 includes the natural air cooling layer 121 and the natural cooling pool 122. The natural air cooling layer 121 is provided with the return water distributor 123. The return water distributor 123 is connected to the cooling water return pipe 114. The feed end of the cooling water upper pipe 113 is provided in the natural cooling pool 122.

[0025] The cabinet 20 is placed in the cabinet placement layer 110 . The cooling coil 220 is provided in the cabinet 20 . The water inlet end of the cooling coil 220 is connected to the first water supply pipe 115 , and the water outlet end is connected to the first water outlet pipe 116 .

[0026] The overall water circulation low-carbon consumption data center system transfers the heat generated by the computer room 10 and the cabinet 20 by passing the cooling medium into the water circulation network 112 and the cooling coil 220, and cools the water curtain formed by the return water distributor 123 by rationally utilizing natural wind. The cooled cooling medium is stored in the natural cooling pool 122, and the cooling medium is cooled by utilizing the cooling characteristics of the land, thereby avoiding the installation of complex cooling devices and saving energy. The power for the circulation of the cooling medium is provided by the heat generated by the computer room 10 and the cabinet 20, and the generated heat will provide circulation power for the cooling medium of the water circulation network 112 and the cooling coil 220, thereby eliminating the need to install additional power facilities.

[0027] For further information, see Figure 1 The water circulation network 112 is provided with at least one cooling water supply pipe 113 in the natural cooling pool.

[0028] Since the overall water circulation low-carbon consumption data center system has no power device, the power for the cooling medium to rise is provided by the heat generated by the cabinet 20. In order to ensure a continuous supply of cooling medium, by imitating the working principle of biological capillaries, the problem of local lack of cooling medium in the water circulation network 112 can be reasonably solved to ensure the continuous circulation of the cooling medium; at the same time, when the heat of the air-conditioning unit is insufficient, the temperature is low at the initial start-up, or the circulating water temperature is high, the power circulation of the cooling medium in the pipeline is insufficient. At this time, a variable frequency pump is set at the inlet end of the water circulation network 112, which can be adjusted according to the heat to achieve the circulation of the cooling medium with minimum power.

[0029] For further information, see Figure 1 The overall water circulation low carbon consumption data center system includes the above-ground water storage device 30. The above-ground water storage device includes an above-ground water reservoir 310 and a first water pump 320. The above-ground water reservoir 310 is located above the ground. The natural cooling pool 122 is connected to the above-ground water reservoir 310 through a water pipe. The first water pump 320 is connected to the water supply pipe.

[0030] The above-ground water storage device 30 can be used in winter. The natural cooling pool 122 is pumped into the above-ground water storage pool 310 through the first water pump 340. Since the underground temperature is higher than the surface temperature in winter, the cooling medium after absorbing heat is passed into the above-ground water storage pool 310 on the surface to better cool down. The cooled cooling water flows back to the natural cooling pool 122 through the pipeline due to gravity and height difference and circulates again.

[0031] For further information, see Figure 1The overall water circulation low-carbon consumption data center system includes the underground cooling medium providing device 40, the underground cooling medium storage device 40 includes the cold water well 410 and the second water pump 420, the cold water well 410 is located below the ground level, the cold water well 410 is connected to the natural cooling pool 122 through a pipeline, and the second water pump is connected to the water supply pipeline.

[0032] The underground cooling medium providing device 40 is suitable for summer. The surface temperature in summer is higher than the underground temperature. Since the land has the effect of being warm in winter and cool in summer, the natural cooling pool 122 flows into the lower cold water well 410 by gravity, and the cooling medium after absorbing heat is cooled. The cooled cooling water is pumped back to the natural cooling pool 122 through the second water pump 420.

[0033] For further information, see Figure 1 The overall water circulation low-carbon consumption data center system includes the direct cooling water pipe 50, the inlet of the direct cooling water pipe 50 is connected to the position of the upper water pipe 430 close to the natural cooling pool 122, and the outlet of the direct cooling water pipe 50 is connected to the water inlet of the water circulation network 112.

[0034] In order to reduce the amount of heat absorbed by the cooling medium before entering the water circulation network 112, a portion or all of the cooling medium in the cold water well 410 can be directly introduced into the water circulation network 112 to improve the cooling efficiency.

[0035] For further information, see Figure 1 The natural air cooling layer 121 is provided with two opposite vents 124 , and the directions of the vents 124 are consistent with the most common wind direction in the local area throughout the year.

[0036] In order to ensure the air intake of the vent 124 , the direction of the vent 124 should be installed according to the most common wind direction of the year to ensure that the natural wind cools the water curtain formed by the return water distributor 123 .

[0037] In a preferred embodiment, see Figure 1 The natural air cooling layer 121 is provided with ventilation slots, a rotatable baffle is provided on the ventilation slots, and two opposite ventilation openings are provided on the rotatable baffle.

[0038] Since the wind direction is not fixed throughout the year, in order to better cool the cooling medium after absorbing heat, the direction of the vent 124 can be rotated by wind force to ensure the air intake.

[0039] For further information, see Figure 1The machine room 10 includes the machine room top 130. The machine room 10 includes the machine room top 130. The machine room top 130 includes several cooling interlayers, and the radius gradually decreases from top to bottom to form a conical top. The cooling interlayer forms a cooling cavity. Two adjacent cooling cavities are connected to each other, and at least one cooling cavity is connected to the water circulation network 112.

[0040] The interior of the machine room roof 130 is hollow, forming a cooling cavity. At the same time, the cooling cavity of the machine room roof 130 is connected to the water circulation pipe network 112, which facilitates the introduction of cooling water into the cooling cavity of the machine room roof 130 and facilitates cooling the hot air rising in the machine room 10.

[0041] For further information, see Figure 1 The exhaust pipe 131 is provided outside the top 130 of the machine room, and the exhaust pipe 131 is higher than the top 130 of the machine room.

[0042] The exhaust pipe 131 is provided on the outside of the top 130 of the machine room. The chimney effect is utilized to form a rapid air flow inside the ventilation pipe 131. The air originally in the ventilation pipe 131 is taken away. At this time, due to the pressure difference, the hot air on the top 130 of the machine room will be discharged to balance the pressure difference and form an upward airflow.

[0043] For further information, see Figure 1 The unpowered fan 132 is provided in the top 130 of the machine room, and the unpowered fan 132 is connected to the top 130 of the machine room.

[0044] The rotational power of the unpowered fan 132 does not require an external power device, which reduces the setting and complexity of the equipment. The unpowered fan 132 is driven by the principle of rising hot air and the characteristics of natural wind circulation to cool the air above the cabinet placement layer 110.

[0045] The above disclosure is only a preferred embodiment of the present invention, and it is certainly not intended to limit the scope of the rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the present invention.
