Under the intelligent outdoor fresh air heat dissipation operation mode, an air duct which is arranged at the top of the BBU cabinet and is used for supplying air to the front of the BBU cabinet is directly connected with the outside through a pipeline and a filter screen, collecting air outdoors, allowing outdoor cold air to enter a direct-connected outdoor air inlet pipeline through a filter screen of the direct-connected outdoor air inlet pipeline, allowing cold air to enter a front cooling cavity of the BBU cabinet from an air inlet duct at the top of the BBU cabinet, allowing cold air to enter an intermediate equipment cavity from the front cooling cavity, allowing the cold air to radiate heat of BBU equipment through a heat radiating unit, discharging hot air discharged from the intermediate equipment cavity into a rear heating cavity, discharging hot air in the rear heating cavity out of the BBU cabinet from a rear air exhaust duct at the top of the BBU cabinet, can be directly discharged indoors or outdoors through a filter screen directly connected with the outdoor exhaust duct and the outdoor exhaust duct, if a plurality of BBU cabinets are arranged indoors, an outdoor air inlet pipeline ventilation pipe network and an outdoor air exhaust pipeline ventilation pipe network can be directly connected, and 5G BBU equipment heat dissipation is achieved. At this moment, the rack-mounted precision air conditioner at the lower part of the BBU cabinet does not work, and the outdoor fresh air heat dissipation operation mode of the BBU cabinet is realized.
Under an intelligent outdoor fresh air heat dissipation operation mode, if the intelligent air control system of the BBU cabinet detects that the cold air volume of the front cold cavity of the BBU cabinet is insufficient (the intelligent air control system of the BBU cabinet detects through the temperature sensing device of the front cold cavity and the temperature sensing device of the rear hot cavity), the fan of the air inlet duct at the bottom of the front door of the BBU cabinet is automatically started, indoor cold air enters the front cold cavity of the BBU cabinet from the air inlet duct at the bottom of the front door of the BBU cabinet, and the insufficient air volume is supplemented, so that auxiliary fresh air supplement is realized; if the intelligent air control system of the BBU cabinet detects that the amount of cold air in the front cold cavity of the BBU cabinet is enough (the intelligent air control system detects through the temperature sensing device of the front cold cavity and the temperature sensing device of the rear hot cavity), auxiliary fresh air supplement is stopped, namely, the fan of the air inlet duct at the bottom of the front door of the BBU cabinet is stopped, and the air inlet duct at the bottom of the front door of the BBU cabinet is closed.
