The data center can adopt the new trend system to cool down network equipment to ensure the normal operating of network equipment in the data center. However, the use of the fresh air system has certain requirements on the cleanliness of the fresh air, so that the application of the fresh air system is limited.

An embodiment of the present invention provides a schematic structural diagram of a data center, where the data center includes a plurality of cabinets 1, as shown in fig. 1, the cabinets 1 may include a plurality of cabinet groups, and each cabinet group includes two cabinets 1 arranged oppositely. The relative arrangement here means that the heat radiation sides of the two cabinets 1 are opposite.

The cabinet 1 is used for deploying network equipment such as servers.

It should be noted that the data center structure shown in fig. 1 is only an example, and those skilled in the art can adjust the structure of the data center as needed, and the present invention is not limited thereto.

In view of the problem of limitation of the application of the fresh air system, as shown in fig. 2, an embodiment of the present invention provides a dust filtration and temperature reduction system applied to the data center, where the system includes air intake chambers 2 symmetrically disposed on two sides of the data center.

As a possible realization mode, a primary filter 3 and a secondary filter 4 are arranged in the air inlet chamber 2, and the primary filter 3 and the secondary filter 4 are arranged in sequence from an air inlet. The sequential arrangement means that after the fresh air enters the dust filtering and cooling system, the fresh air is firstly filtered by the primary filter 3 and then filtered by the secondary filter 4.

Further, the primary filter 3 and the secondary filter 4 are used for filtering fresh air, and the filtering grade of the secondary filter 4 is higher than that of the primary filter.

It should be noted that the primary filter 3 may be a coarse filter, the secondary filter 4 may be a medium filter, for example, the primary filter 3 may be a coarse filter screen, and the secondary filter 4 may be a bag filter, etc.

After the fresh air is filtered through the coarse effect of the primary filter 3, the secondary filter 4 is used for filtering the intermediate effect, so that the fresh air can meet the application requirement of a dust filtering and cooling system, and impurities such as dust are prevented from entering a data center.

In some embodiments, depending on the cleanliness requirement of the data center, one skilled in the art may also adjust the filter as needed, such as adding a tertiary filter after the secondary filter 4, which may be a high efficiency filter.

It should be noted that, because the filter is used for filtering the fresh air, in order to avoid the damage of the filter caused by the overlarge wind speed of the fresh air, when the dust filtration cooling system is deployed, the overlarge wind speed of the inlet wind of the system is also needed to be avoided, and if the dust filtration cooling system is deployed in a scene where the wind speed is lower than a set value.

According to the dust filtering and cooling system provided by the embodiment of the utility model, the primary filter and the secondary filter are arranged in the air inlet chamber of the dust filtering and cooling system, and the fresh air entering the system is filtered in a grading manner through the primary filter and the secondary filter, so that the influence of impurities such as dust in the fresh air on the dust filtering and cooling system is avoided, the requirement of the dust filtering and cooling system on the cleanliness of the fresh air is reduced, and the dust filtering and cooling system can be applied to more scenes.

In some embodiments, as shown in fig. 2, the air intake chamber 2 further includes a fresh air louver 5 and at least one circulation fan 6, the fresh air louver 5 is disposed at an air inlet of the air intake chamber 2, and the circulation fan 6 is disposed at an air outlet of the air intake chamber 2.

As a possible implementation manner, the fresh air louver 5 may also have a certain filtering function for the fresh air entering the dust filtering and cooling system, such as preventing impurities such as dust and rain water from entering the dust filtering and cooling system.

The circulating fan 6 can send fresh air in the air inlet chamber 2 into the data center. Because the fresh air passes through the fresh air shutter 5, the primary filter 3 and the secondary filter 4, the filtered fresh air is temporarily stored in the air inlet chamber 2, and the filtered fresh air can be sent into the data center under the action of the circulating fan 6.

Furthermore, the number of the circulating fans 6 can be adjusted according to the heat exchange requirement of the dust filtration and cooling system. The heat transfer demand of dust filtration cooling system here can be confirmed according to the heat that the rack gived off in the data center, and the heat that the rack gived off in the data center is more, and then the heat that dust filtration cooling system needs the exchange is also more, and the new amount of wind that gets into the data center this moment also increases, can be through the quantity that increases circulating fan 6 this moment promptly to increase the new amount of wind that gets into the data center.

Of course, when a plurality of circulating fans 6 are arranged in the air inlet chamber 2, the fault tolerance of the dust filtering and cooling system can be increased, and when part of the circulating fans 6 are in fault, other circulating fans 6 can still support the air inlet requirement of the dust filtering and cooling system.

In the concrete use, the new trend gets into air inlet cavity 2, after filtering by primary filter 3 and secondary filter 4, can send into data center based on 6 effect of circulating fan with the new trend after filtering to rack 1 in the data center cools down.

In some embodiments, as shown in fig. 3, the dust filtering and cooling system provided in the above embodiments further includes a dust filtering and cooling chamber 7, where the dust filtering and cooling chamber 7 is an overhead layer disposed below the data center.

As a possible implementation manner, the air outlet of the circulating fan 6 is communicated with the dust filtering and cooling chamber 7.

In some embodiments, as shown in fig. 3, a water pipeline 8 and a water chute 9 are horizontally arranged in the dust filtration and temperature reduction chamber 7.

As a possible implementation manner, at least one spray head is arranged on the water pipeline 8, and the distance between the water pipeline 8 and the top of the dust filtering and cooling chamber 7 is smaller than the distance between the water pipeline 8 and the bottom of the dust filtering and cooling chamber 7; the water chute 9 is arranged at the bottom of the dust filtering and cooling chamber 7.

Furthermore, because the dust filtering and cooling chamber 7 is arranged on the overhead layer below the data center, and the air inlet chamber 2 and the two sides arranged on the data center are arranged, therefore, for the fresh air of the air inlet chamber 2 to enter the air inlet chamber 2, the circulating fan 6 can be a centrifugal fan, so that the filtered fresh air in the air inlet chamber 2 can turn to enter the dust filtering and cooling chamber 7.

It should be noted that, in this embodiment, the circulating fan 6 is a dc brushless motor, and independent speed regulation control of the motor can be realized, so as to facilitate cooperation of the circulating fans 6.

In a possible implementation mode, when the temperature of the fresh air outside the data center is higher than or equal to the first temperature T1, the fresh air introduced from the outside cannot meet the cooling requirement of the cabinet in the data center, so that the spray head on the water pipeline 8 can be opened, and the cooling liquid sprayed by the spray head can further cool the fresh air in the dust filtration cooling cavity 7 so as to meet the cooling requirement of the cabinet in the data center.

The dust filtering and cooling chamber 7 is used for cooling fresh air and can further filter the fresh air through water mist sprayed by the spray head.

When the water pipeline 8 is used for further cooling the fresh air, the water guide groove 9 can collect the cooling liquid sprayed by the spray head and discharge the collected cooling liquid.

In another possible implementation manner, when the temperature of the fresh air outside the data center is higher than the second temperature T2 and is lower than the first temperature T1, the fresh air introduced from the outside can meet the cooling requirement of the cabinet in the data center, the spray head on the water pipeline 8 can be closed at this time, and the cabinet in the data center is cooled only by the filtered fresh air.

In some embodiments, as shown in fig. 4, the dust-filtering temperature-reducing system provided in the above embodiments further includes a hot airflow chamber 10 and at least one cold airflow chamber 11, and the cold airflow chamber 11 is disposed in the hot airflow chamber 10 and between the cabinets 1.

As a possible implementation mode, the cold air flow cavity 11 is arranged between the cabinets 1, so that the cabinets on two sides can be cooled by the cold air flow cavity 11, and the cooling efficiency of fresh air in the cold air flow cavity 11 is improved.

Further, the cooling air flow chamber 11 is disposed between the heat radiation sides of the two cabinets 1.

In some embodiments, as shown in fig. 4, a hollow plate 12 is disposed below the cold airflow chamber 11, and the cold airflow chamber 11 is communicated with the dust filtration and temperature reduction chamber 7 through the hollow plate 12.

As a possible implementation, the fresh air in the cold airflow chamber 11 can be provided by the dust filtering and temperature reducing chamber 7. When the circulating fan 6 continuously sucks fresh air into the dust filtering and cooling cavity 7, the pressure in the dust filtering and cooling cavity 7 is continuously increased, and then the fresh air can enter the cold air flow cavity 11 through the hollow plate 12 to cool the cabinets on two sides of the cold air flow cavity 11.

In some embodiments, as shown in fig. 5, the hot air chamber 10 further includes a diversion damper 13 symmetrically disposed on both sides of the hot air chamber 10.

As a possible implementation manner, the fresh air absorbs heat in the cold airflow cavity 11 and is called as hot airflow, and then enters the hot airflow cavity 10. The diversion damper 13 can make the hot air flow discharged from the cold air flow cavity 11 form return air in the hot air flow cavity 10.

In a possible implementation manner, when the temperature of the fresh air outside the data center is lower than or equal to the second temperature, if the fresh air introduced outdoors is directly introduced into the cold air flow chamber 11, condensation of network equipment in the cabinet may be caused due to too low temperature of the fresh air, which affects the performance of the network equipment. Therefore, when the temperature of the fresh air outside the data center is lower than or equal to the second temperature, the spray head on the water pipeline 8 can be closed, and the air guide valve 13 is opened at the same time, so that the hot air in the hot air chamber 10 forms return air, the fresh air and the return air in the cold air chamber 11 are mixed, and condensation of network equipment is avoided.

In some embodiments, as shown in fig. 5, the dust-filtering temperature-reducing system provided in the above embodiments further includes at least one exhaust cap 14, and the exhaust cap 14 is disposed on the top of the hot air flow chamber 10.

As a possible implementation manner, the exhaust cap 14 is communicated with the outside of the data center, and when the cold airflow chamber 11 continuously exhausts the hot airflow to the hot airflow chamber 10, the hot airflow can be exhausted to the outside through the exhaust cap 14.

In some embodiments, the exhaust cap 14 is provided with an electric air valve 15, and the electric air valve 15 is disposed at a communication position of the exhaust cap 14 and the hot air flow chamber 10.

As a possible implementation, the hot air flow outlet of the hood 14 can be adjusted by an electric air valve 15. For example, when the cold airflow chamber 11 discharges a large amount of hot airflow to the hot airflow chamber 10, the hot airflow discharge amount of the exhaust cap 14 can be increased by the electric air valve 15; when the hot air flow discharged from the cold air flow chamber 11 to the hot air flow chamber 10 is reduced, the hot air flow discharge amount of the exhaust cap 14 can be reduced by the electric air valve 15.

In some embodiments, the intake chamber 2 further includes a pressure difference alarm device, the pressure difference alarm device corresponds to the primary filter 3 and the secondary filter 4, and the pressure difference alarm device is disposed at the primary filter 3 and the secondary filter 4.

As a possible implementation manner, a first pressure difference warning device may be arranged at the primary filter 3, and a second pressure difference warning device may be arranged at the secondary filter 4; the first pressure difference warning device may detect a first pressure difference across the primary filter 3 and the second pressure difference warning device may detect a second pressure difference across the secondary filter 4.

When the first pressure difference is greater than or equal to the first preset value, it can be determined that the resistance of the primary filter 3 for filtering fresh air is too large, and at the moment, impurities such as dust and the like adsorbed on the primary filter 3 are more, so that the filtering efficiency of the primary filter 3 for the fresh air is influenced, and therefore, a maintainer can maintain the primary filter 3 at the moment; similarly, when the second pressure difference is greater than or equal to the second preset value, it can be determined that the resistance of the secondary filter 4 to filter the fresh air is too large, and at this time, impurities such as dust adsorbed on the secondary filter 4 are more, which affects the filtering efficiency of the secondary filter 4 to the fresh air, so that the secondary filter 4 can be maintained by maintenance personnel at this time.

Furthermore, the maintenance of the primary filter 3 and the secondary filter 4 can also reduce the energy consumption of the circulating fan 6 when fresh air is sucked.
