An outdoor cooling unit for a vehicular air conditioning apparatus comprising: - a casing including an outlet section, inlet sections and a base, the outlet section formed on a top surface of the casing, the inlet sections each being formed on one of both sides of the outlet section to have an inlet plane inclined against the base by having a distance to the base decreasing in a direction from the outlet section to outside; - a first heat exchanger disposed to face one of the inlet sections and a second heat exchanger disposed to face another of the inlet sections; - at least one propeller fan having a boss to rotate about an axis of the propeller fan and a plurality of blades disposed on an outer periphery of the boss and disposed in the casing to face the outlet section; and - a motor to rotate the propeller fan, wherein where a normal line to the base of the casing is defined as a z axis and a direction from the base toward the top surface is defined as a positive direction of the z axis, the propeller fan is disposed to have the axis along the z axis and blow air in a positive direction of the z axis, an angle formed between the normal line to the inlet plane and the z axis is an acute angle, each of the blades is defined by a blade chord center point on an inner peripheral end thereof and another blade chord center point on an outer peripheral end thereof, positioned so that a line segment connecting therebetween has an inclination determined by position in the positive direction of z axis determined proportional to closeness to outer periphery of the blade, and a blade chord center line connecting the blade chord center points from the inner peripheral end of the blade to the outer peripheral end of the blade forms a curve being convex in the positive direction of the z axis across the entire area in a radius direction, wherein, when a direction in which the inlet sections are juxtaposed in a plane, the plane being vertical to the z axis, is defined as an x axis, a direction vertical to the x axis and the z axis is defined as a y axis, one of side surfaces of the casing opposed to each other in the y axis direction is defined as a first side surface, another of side surfaces of the casing opposed to each other in the y axis direction is defined as a second side surface, an end of a y axis direction side edge located closer to the first side surface than another end is defined as a P1 point, the y axis direction side edge being one of the y axis direction side edges extending in the y axis direction of the first heat exchanger, the y axis direction side edge located more away from the propeller fan than another of the y axis direction side edges of the first heat exchanger, an end of a y axis direction side edge located closer to the first side surface than another end is defined as a P2 point, the y axis direction side edge being one of the y axis direction side edges extending in the y axis direction of the second heat exchanger, the y axis direction side edge located more away from the propeller fan than another of the y axis direction side edges of the second heat exchanger, an end of the y axis direction side edge located closer to the second side surface than the end is defined as a P3 point, the y axis direction side edge being one of the y axis direction side edges extending in the y axis direction of the first heat exchanger, the y axis direction side edge located more away from the propeller fan than the other of the y axis direction side edges of the first heat exchanger, an end of the y axis direction side edge located closer to the second side surface than the other end is defined as a P4 point, the y axis direction side edge being one of the y axis direction side edges extending in the y axis direction of the second heat exchanger, the y axis direction side edge located more away from the propeller fan than the other of the y axis direction side edges of the second heat exchanger, one of points, in a plane vertical to the z axis, at which the y axis passing through the axis of the propeller fan adjacent to the first side surface crosses an outer peripheral end rim of the propeller fan, the point being located facing the first side surface, is defined as a Q1 point, and one of points, in a plane vertical to the z axis, at which the y axis passing through the axis of the propeller fan adjacent to the second side surface crosses an outer peripheral end rim of the propeller fan, the point being located facing the second side surface, is defined as a Q2 point, a non-ventilation areas is disposed in at least one of an area surrounded by the P1 point, P2 point and Q1 point and an area surrounded by the P3 point, P4 point and Q2 point so as not to interfere with the first heat exchanger and the second heat exchanger and so as to prevent generation of stagnation vortex in an area in which the non-ventilation area is provided. - a casing including an outlet section, inlet sections and a base, the outlet section formed on a top surface of the casing, the inlet sections each being formed on one of both sides of the outlet section to have an inlet plane inclined against the base by having a distance to the base decreasing in a direction from the outlet section to outside; - a first heat exchanger disposed to face one of the inlet sections and a second heat exchanger disposed to face another of the inlet sections; - at least one propeller fan having a boss to rotate about an axis of the propeller fan and a plurality of blades disposed on an outer periphery of the boss and disposed in the casing to face the outlet section; and - a motor to rotate the propeller fan, wherein
