摘要： An object is to provide a vehicle heat-exchange module capable of optimizing the whole of a stator blade that deflects a flow in the swirling direction produced by a cooling fan, thereby reducing the work performed by the cooling fan and eventually reducing the input power to the cooling fan, and to provide a vehicle having the vehicle heat-exchange module. According to the vehicle heat-exchange module (10), the stator blade (30) arranged on the downstream side of the cooling fan (16) is divided by an intermediate ring (31) into inner-circumference-side stator blade members (32A) and outer-circumference-side stator blade members (32B), and the number of the inner-circumference-side stator blade members (32A) for installation is made smaller than that of the outer-circumference-side stator blade members (32B), thus setting the pitch/chord ratio within an appropriate range at each of the inner circumference side and the outer circumference side. As a result, a flow in the swirling direction produced by the cooling fan (16) is efficiently deflected by the whole of the stator blade (30), thereby reducing the work performed by the cooling fan (16) and eventually reducing the input power to the cooling fan (16).

The damper includes a wall surface which forms an air flow passage, a stationary portion which extends from the wall surface to the center of a flow passage, and a rotating portion rotatably disposed in the flow passage, having one end in contact with a portion of the stationary portion at a downstream side of an air flow through the flow passage. A curved wall portion as a convex curved surface protruding to the center of the flow passage is formed on a position of the wall surface on which the air flow passing between the one end and the stationary portion impinges.

The centrifugal blower is provided with: an impeller; a casing that houses the impeller and forms a spiral flow passage that surrounds a radial direction outside of the impeller; and a driving device that rotates the impeller about an axis. The impeller has: a bottom plate; a plurality of blades provided on a same circumference of the bottom plate; and a substantially annular plate shape shroud that has the blades interposed between it and the bottom plate, and that is disposed concentric with the bottom plate, and that connects end sections of the respective blades. The shroud has: an inclined section that comes closer to the bottom plate moving from a radial direction inside to a radial direction outside; and a shroud side barrier that rises from a position on the radial direction outside of the inclined section towards a side opposite to the bottom plate. The casing is provided with a bell-mouth that opens from a radial direction inside of the shroud to a radial direction outside, and a casing side barrier that projects to an area between the inner periphery of the shroud and the shroud side barrier.
