[0022] Therefore, when one air outlet 401 faces the first connecting pipe 6, the inside of the inner sleeve 4 is connected with the first connecting pipe 6 through the air outlet 401, and the other air outlet 401 is covered by the outer sleeve 5, so that when the fan 3 works, the airflow enters the first connecting pipe 6 through the air outlet 401, and then the cold air outside enters the inside of the cabinet 2 through the bottom wall of the cabinet 2 to perform heat dissipation work, and finally the hot air is discharged from the exhaust hole at the upper end of the cabinet 2, so that the heat dissipation effect of the bottom air inlet and the top air outlet in the conventional technology is realized.

[0023] When the air needs to be taken in from the upper end of the side wall of the cabinet 2 to cool the high-level equipment inside the cabinet 2, the inner sleeve 4 can be driven to rotate, so that the air outlet 401 originally covered by the second connecting pipe 7 is opposite to the lower end, and the air outlet 401 originally opposite to the first connecting pipe 6 is rotated to be covered by the outer sleeve 5, then the air can enter the second connecting pipe 7 through the air outlet 401, and then enter the inside of the cabinet 2 through the side wall of the cabinet 2;

[0024] The motor 8 is fixed on the outer wall of the end of the second connecting pipe 7 close to the outer sleeve 5, the axis of the output shaft of the motor 8 coincides with the axis of the inner sleeve 4, the output shaft of the motor 8 is fixed to the outer wall of the end of the inner sleeve 4 away from the fan 3, and the rotation of the motor 8 drives the rotation of the inner sleeve 4 to switch the air outlet end of the fan 3, the reinforcing ring is fixed to the center of the end of the inner sleeve 4 close to the motor 8, the output shaft of the motor 8 is fixed to the inner wall of the reinforcing ring, and the reinforcing ring can strengthen the strength of the connection between the inner sleeve 4 and the output end of the motor 8;
