When the temperature collected by the first temperature sensor is lower than the second set value, the second set value is less than the first set value, and the controller turns off the cooling fan 14 and the air conditioner 15. Since the external temperature of the cabinet 1 is low, It uses natural heat dissipation to dissipate heat; if the temperature collected by the second temperature sensor reaches the third set value, the controller starts the heat dissipation fan 14 and turns off the air conditioner 15. At this time, the internal temperature of the cabinet 1 is slightly higher, and it uses heat dissipation. The fan 14 dissipates heat; if the temperature collected by the second temperature sensor reaches the fourth set value, and the fourth set value is greater than the third set value, the controller starts the air conditioner 15 and turns off the heat dissipation fan 14. At this time, the cabinet The internal temperature of the body 1 is relatively high, and the air conditioner 15 is used to dissipate heat. Wherein, the startup and shutdown conditions of the cooling fan 14 and the air conditioner 15 are the stable temperatures collected by the first temperature sensor and the second temperature sensor. The first set value, the second set value, the third set value and the fourth set value can all be set according to the user's situation.

If the air temperature is slightly higher, the cooling fan 14 is used to dissipate heat; if the temperature collected by the second temperature sensor reaches the sixth set value, the controller starts the air conditioner 15 and turns off the cooling fan 14. At this time, the cold air outside the cabinet 1 If the temperature is slightly higher and the internal temperature of the cabinet 1 is relatively high, the cooling effect of the cooling fan 14 may be poor.

If the temperature collected by the first temperature sensor reaches the seventh set value, and the seventh set value is greater than the fifth set value, the controller starts the air conditioner 15 and turns off the cooling fan 14. At this time, the temperature of the cold air outside the cabinet 1 If the temperature is higher, the air conditioner 15 is used for heat dissipation; if the temperature collected by the second temperature sensor reaches the alarm set value, the alarm set value is greater than the seventh set value, the controller turns off the air conditioner 15 and starts the cooling fan 14 . At this time, the internal temperature of the cabinet 1 is too high, indicating that the air conditioner 15 is abnormal and cannot dissipate heat for the cabinet 1. Therefore, the cooling fan 14 is activated and the cooling fan 14 is used for heat dissipation. Wherein, the startup and shutdown conditions of the cooling fan 14 and the air conditioner 15 are the stable temperatures collected by the first temperature sensor and the second temperature sensor. The fifth set value, sixth set value, seventh set value and alarm set value can all be set according to the user's situation. According to different temperatures, the cooling fan 14 and the air conditioner 15 operate alternately, which can effectively save money energy, and prolong the life of the equipment.

8. The communication cabinet according to any one of claims 1 to 7, wherein the airflow generating device comprises a heat dissipation fan (14), and a controller is connected to the heat dissipation fan (14), and a temperature detection unit is connected to the controller.

9. The communication cabinet according to claim 8, wherein the airflow generating device further comprises an air conditioning device (15), the air conditioning device (15) is connected with the controller, and the temperature detecting unit comprises a first temperature sensor and a second temperature sensor, and the first temperature sensor and the second temperature sensor are respectively used for detecting the external temperature and the internal temperature of the cabinet body (1).

10. A method of operating a telecommunications cabinet as claimed in claim 9, including the steps of:

the controller judges whether the external temperature of the cabinet body (1) detected by the first temperature sensor is lower than a first set value, if so, the controller adopts a first working mode; if not, the controller adopts a second working mode;

the first operating mode includes:

when the temperature collected by the first temperature sensor is lower than a second set value, the second set value is smaller than the first set value, and the controller closes the cooling fan (14) and the air conditioning equipment (15); if the temperature collected by the second temperature sensor reaches a third set value, the controller starts the cooling fan (14) and closes the air conditioning equipment (15); if the temperature collected by the second temperature sensor reaches a fourth set value, the fourth set value is larger than the third set value, the controller starts the air conditioning equipment (15) and closes the cooling fan (14);

the second operating mode includes:

when the temperature acquired by the first temperature sensor is lower than a fifth set value, the fifth set value is larger than the first set value, and the controller starts the cooling fan (14) and closes the air conditioning equipment (15); if the temperature collected by the second temperature sensor reaches a sixth set value, the controller starts the air conditioning equipment (15) and closes the cooling fan (14);

if the temperature collected by the first temperature sensor reaches a seventh set value, the seventh set value is larger than the fifth set value, the controller starts the air conditioning equipment (15) and closes the cooling fan (14); and if the temperature acquired by the second temperature sensor reaches an alarm set value, the alarm set value is greater than a seventh set value, the controller closes the air conditioning equipment (15) and starts the cooling fan (14).
