After the passive air inlet device 1 collects outdoor fresh air, the fresh air can be sent into the data center under the action of wind force so as to cool the cabinet in the data center.
It should be noted that, according to the cooling requirement of the data center, a person skilled in the art can adjust the number of the passive air intake devices 1 around the data center. For example, when the number of cabinets in the data center is large, the number of passive air intake devices 1 on the opposite side of the periphery of the data center may be increased, for example, 2 or 3 passive air intake devices 1 may be provided on the opposite side; when the number of the cabinets in the data center is small, the number of the passive air intake devices 2 on the opposite side of the periphery of the data center can be reduced, and if the number of the passive air intake devices arranged on the opposite side is 1.
Of course, the passive air intake devices 1 may be disposed only on two sides of the data center, or may be disposed around the data center, and the embodiment of the present application is not limited.

In some embodiments, as shown in fig. 3, the passive cooling system further comprises a cold airflow channel 5, and the cold airflow channel 5 is communicated with the overhead airflow channel 3.
The cold airflow channel 5 is disposed in the data center and between the cabinets.
As a possible implementation manner, the cold airflow channel 5 is disposed between the cabinets, and the heat dissipation side of the cabinet is opposite to the cold airflow channel 5, so that the cold airflow channel 5 can cool down the cabinets on both sides at the same time, so as to improve the cooling efficiency of the cabinets.
In some embodiments, as shown in fig. 3, a hollow plate 6 is disposed at a connection position of the cold airflow channel 5 and the overhead airflow channel 3, and the cold airflow channel 5 is communicated with the overhead airflow channel 3 through the hollow plate 6.

In some embodiments, as shown in fig. 4, an electric air valve 7 is disposed at the connection between the passive air intake device 1 and the overhead airflow channel 3.
As a possible implementation, the electric air valve 7 can control the air supply amount of the passive air intake device 5 to the data center. For example, when the wind speed of the fresh air outside the data center is high, the air intake of the fresh air can be reduced through the electric air valve 7, so that the situation that the air volume entering the data center at the same time is high and the use experience of a passive cooling system is influenced is avoided; when the speed of the fresh air outside the data center is low, the air inlet volume of the fresh air can be increased through the electric air valve 7, so that the cooling requirement of the cabinet in the data center is met.

When the circulating fan 8 is started, the rotating speed of the circulating fan 8 can be correspondingly adjusted according to the temperature detected by the temperature sensor so as to adjust the fresh air volume delivered to the data center. The temperature sensor is not shown in the figure.
For example, when the temperature detected by the temperature sensor increases, the rotation speed of the circulation fan 8 may be increased to increase the amount of fresh air delivered to the data center; when the temperature detected by the temperature sensor decreases, the rotation speed of the circulation fan 8 may be reduced to reduce the amount of fresh air sent to the data center.
Since the rotational speed of the circulation fan 8 can be adjusted according to the temperature detected by the temperature sensor, the power consumption of the circulation fan 8 can be reduced.
Further, when the temperature detected by the temperature sensor is less than the first set value, the circulating fan 8 may be turned off; when the temperature detected by the temperature sensor is greater than or equal to the first set value, the circulating fan 8 can be started, and the rotating speed of the circulating fan 8 is continuously adjusted according to the actually detected temperature value.

Because the electric exhaust valve 9 is arranged at the exhaust outlet of the data center, the exhaust outlet is positioned at the top of the data center, and the air inlet of the data center is actually a communication port at the hollow-out plate 6, a height difference exists between the air inlet of the data center and the exhaust outlet thereof; and based on the density difference between the hot air flow and the cold air flow (fresh air), the hot air flow rises in the data center and is exhausted by the air outlet; along with the rising and discharging of hot air flow in the data center, fresh air in the overhead airflow channel 3 can enter the cold airflow channel 5, so that the cabinet is cooled.
In one possible implementation, the electric exhaust valve 9 may be disposed on a hollow-out top plate in the data center, so as to separate the exhaust system from the cabinet in the data center.
It should be noted that, in the present application, the electric air valve 7 and the electric air exhaust valve 9 are respectively used for controlling air intake and air exhaust of the passive cooling system, so that when the passive cooling system is opened, the electric air valve 7 and the electric air exhaust valve 9 are also opened at the same time; when the passive cooling system is closed, the electric air valve 7 and the electric air exhaust valve 9 can be closed.
