When the detection value of the temperature sensor is larger than the first preset value upper limit (namely a first temperature threshold) of the main controller, the main controller controls the box fan 8 to be started, hot air in the server cabinet 1 is extracted through the box fan 8 and is conveyed into a cooling box body at the bottom, and an internal cooling mechanism in the cooling box body cools and dissipates the hot air, so that heat in the server cabinet 1 is transferred, and the cooling effect in the server cabinet 1 is realized;
meanwhile, the air compressor can be controlled to be started, and compressed air enters the vortex tube 9 for separation; the cold air sprayed from the cold air end on the vortex tube 9 is led into the server cabinet 1 through a cold air pipeline, so that the rapid cooling and cooling treatment of the inside of the server cabinet 1 are realized.
Further, the method further comprises:
when the real-time temperature value is larger than the second temperature threshold value, controlling the push rod mechanism to extend and increase the distance between two adjacent server cabinets 1; wherein the second temperature threshold is not less than the first temperature threshold.
In a specific embodiment, when the detection value of the temperature sensor is greater than the second preset value upper limit (i.e., the second temperature threshold) of the main controller, the main controller simultaneously controls the plurality of electro-hydraulic push rods 4 to simultaneously extend, so that the distance between two adjacent server cabinets 1 is increased, and the cooling effect on the server cabinets 1 is further improved; wherein the second predetermined upper limit is greater than or equal to the first predetermined upper limit, i.e., the electro-hydraulic push rod 4 may be extended or extended at the same time.
The distance between two adjacent cooling boxes can be monitored through a distance sensor, so that the distance can be accurately controlled.
