Abstract

Outdoor unit (10) for a heat pump comprising a refrigerant circuit, the outdoor unit (10) comprising a casing (11), a fan (50) accommodated in the casing, the fan (50) having fan blades (55) rotatable about an axis of rotation (56), a grille (100) covering the fan blades (55), characterized in that at least an outer surface (101) of the grille is outwardly curved; the grille (100) is divided into a first area (A1) and a second area (A2), the first area (A1) being defined so that the distance (D) between the fan blades (55) and the outer surface (101) of the grille (100) is not more than a first threshold, and the second area (A1) being defined so that the distance (D) between the fan blades (55) and the outer surface (101) of the grille (100) is larger than the first threshold, wherein openings (102) are formed in the first (A1) and second (A2) areas of the grille (100), a smallest dimension of each of the openings (102) in the first area (A1) perpendicular to the axis of rotation (56) of the fan blades (55) is not more than a second threshold and a smallest dimension of at least some of the openings (102) in the second area (A2) perpendicular to the axis of rotation (56) of the fan blades (55) is larger than the second threshold.
