The casing unit (3) includes a casing body (31) formed with a receiving space (310) and an air outlet port (318), a porous plate (32) formed with a plurality of through holes (329) and is disposed in the receiving space (310) to divide the receiving space (310) into an air-flowing room (301) and a noise-reduction room (302), and an air-entering tube (33) in spatial communication with the air-flowing room (301) . The fan impeller unit (4) is disposed in the air-flowing room (301) and rotatable to generate airflow partially flowing from the air-flowing room (301) into the noise-reduction room (302) through the through holes (329).
