Abstract

This external cooling unit (100) of a vehicular air conditioning device is configured such that the normal of the suction face of a suction section (12) and the normal of the discharge face of a discharge section (13) form an acute angle and a flow of air inside a case (10) forms a substantially check mark shaped (substantially V shaped or substantially U shaped) path wherein each blade (22) of an axial blower (2) is configured such that a chord center line (226) which is formed by connecting the chord center points (225) between the inner circumferential edge (223) and the outer circumferential edge (224) of the blade (22) and projecting the resultant line onto a plane face which includes a rotary shaft forms a convex curve toward the downstream side in the entire region in the radial direction.
