The other end of the L-shaped air guide tube 15 is connected to the air inlet of the axial flow fan 4. The L-shaped air guide tube 15 is a double-layer tube with a spiral pattern on the inner wall for noise reduction. The air outlet of the axial flow fan 4 is fixedly connected to the top of the same side of the outer shell 1, and the air deflector 5 is installed inside the same side of the outer shell 1 and is connected to the axial flow fan 4. Four temperature sensors 6 are installed inside the other end of the outer shell 1. A ventilation adapter duct 9 is installed at the upper end of each of the air inlet rectangular tube 13 and the air outlet rectangular tube 14. A circular arc deflector 18 is installed at the lower end of the air inlet rectangular tube 13, located on the side of the air outlet rectangular tube 14, with the end of the circular arc deflector 18 pointing towards the air deflector 5.

[0037] The inner wall of one end of the outer shell 1 for installing the temperature sensor 6 is provided with three equally dividing partition plates 16, and a guide arc plate 17 is provided on the upper end between two adjacent partition plates 16 and the upper end between the partition plate 16 and the inner wall of the outer shell 1; the temperature sensor 6 is installed on the guide arc plate 17, and a base plate for sealing is provided at the lower end of the outer shell 1.

[0038] The air guide 5 includes a rectangular trough body 51 with a side opening, a first servo motor 52, and an air guide tube 53; the first servo motor 52 and the air guide tube 53 are both installed inside the rectangular trough body 51, and the first servo motor 52 is located on the lower side to drive the air guide tube 53 to rotate; a second circular through hole 511 connected to the axial flow fan 4 is provided at the upper end of the rectangular trough body 51; the air guide tube 53 includes a closed cylindrical tank 531; the outer wall of the cylindrical tank 531 is fixedly connected to a rectangular air outlet pipe 532 arranged along the axial direction; a third circular through hole 533 cooperating with the second circular through hole 511 is provided at the upper end of the cylindrical tank 531; a circular arc plate 512 cooperating with the outer wall of the cylindrical tank 531 is fixed on each of the two side walls at the opening of the rectangular trough body 51.

[0039] A guide plate 7 is mounted on the inner wall of the rectangular air intake tube 13 via a bearing. A second servo motor 8 is fixed to the outer wall of the rectangular air intake tube 13 to drive the shaft of the guide plate 7. The guide plate 7 is used to control the different air intake volumes of the four axial flow fans 4 and assist in adjusting the airflow below.

[0040] The four axial flow fans 4, the four air guides 5, the four temperature sensors 6, and the second servo motor 8 are all connected and installed on a controller.

By monitoring the temperature of the outflowing airflow and determining the heat dissipation temperature changes across the entire CT equipment area, the four air deflectors 5 adaptively adjust the air outlet direction based on the temperature comparison of the four temperature sensors 6, increasing the airflow in the high-heat dissipation area to rapidly respond to heat dissipation in the high-temperature areas of the CT equipment.
