The lateral direction of the heat exchanger 20 refers to a horizontal direction, and the longitudinal direction refers to a direction perpendicular to the lateral direction. When the heat exchanger 20 is vertically disposed, the longitudinal direction refers to the vertical direction; when the heat exchanger 20 is disposed obliquely, the longitudinal direction refers to a direction perpendicular to the lateral direction, but not a vertical direction, but a direction closer to or coincident with the oblique direction of the heat exchanger 20. The sweeper brush 310 can be maintained within a range of distances from the surface of the heat exchanger 20 as it moves longitudinally along the heat exchanger 20. The distance range should be less than the bristle length of the sweeper brush 310.

As an example, the guide rail 320 is provided at an inner sidewall of the housing 10. The guide rail 320 is disposed on the inner sidewall of the housing 10, which facilitates the fixing of the guide rail 320 and eliminates the need for additional members for fixing the guide rail 320.
