摘要： A diffuser (10) comprises a lower element (12) and an upper element (14) fixed on the lower element (12). The upper element (14) and the lower element (12) are separately formed. The lower element (12) comprises a lower inner wall (120) and a lower outer wall (122). The upper element (14) comprises an upper inner wall (140) and an upper outer wall (142). The upper inner wall (140) is connected to the lower inner wall (120) to form an internal air-guiding surface (16). The upper outer wall (142) is connected to the lower outer wall (122) to form an external air-guiding surface (18). The internal air-guiding surface (16) is disposed to opposite to the external air-guiding surface (18) to define an air-guiding channel (20) for air flow diffusion. The upper element (14) further comprises an air-guiding wing (144) connecting the upper inner wall (140) to the upper outer wall (142). The lower element (12) further comprises a lower air-guiding wing (124) connecting the lower inner wall (120) to the lower outer wall (122). The air-guiding wing (144) is connected to the lower air-guiding wing (124) to form an air-guiding wing (22) connecting the internal air-guiding surface (16) to the external air-guiding surface (18). The diffuser reduces fracture of the air-guiding wing caused by a contraction deformation, and the diffuser structure is simple and convenient to mount and detach. Also disclosed are a centrifugal compression power system and vaneless fan.
