A diffuser includes a lower element and an upper element. The upper element is fixed on the lower element, and the upper element and the lower element are formed separately. The lower element includes a lower inner wall and a lower outer wall, and the upper element includes an upper inner wall and an upper outer wall. The upper inner wall is connected to the lower inner wall to form an internal air-guiding surface, the upper outer wall is connected to the lower outer wall to form an external air-guiding surface, and the internal air-guiding surface is disposed opposite to the external air-guiding surface to define an air-guiding channel for air flow diffusion. The upper element further includes an upper air-guiding wing for connecting the upper inner wall and the upper outer wall, and the lower element further includes a lower air-guiding wing for connecting the lower inner wall and the lower outer wall.
