发明名称 VEHICLE FRONT PORTION STRUCTURE
摘要 To provide a vehicle front portion structure that can sufficiently ensure an amount of cooling wind that is introduced into a cooling unit disposed at a rear of a power unit. A vehicle front portion structure has: a power unit that is fixed to an interior of a power unit room; a cooling unit provided at a rear of the power unit; an undercover that adjusts a flow of air flowing through a lower portion of a vehicle; a cooling wind introducing hole that is provided in the undercover at a rear of the power unit and in front of the cooling unit; and a cooling wind introducing passage that blows out air, that has been introduced from a front side opening end portion, toward the cooling unit from a rear side opening end portion that is provided above the cooling wind introducing hole, at a flow velocity that is faster than a flow velocity of the air flowing through the lower portion of the vehicle.

主权项 1. A vehicle front portion structure comprising: a power unit that is fixed to an interior of a power unit room provided at a front portion of a vehicle; a cooling unit provided at a rear of the power unit; a shroud that guides air flowing toward the cooling unit; an undercover that is provided below the power unit and the cooling unit, and that adjusts a flow of air flowing through a lower portion of the vehicle; a cooling wind introducing hole that is provided in the undercover at a rear of the power unit and in front of the cooling unit, and that introduces, into the cooling unit, the air flowing through the lower portion of the vehicle; and a cooling wind introducing passage that has a front side opening end portion introducing air from a front side of the vehicle, and that blows out air, that has been introduced from the front side opening end portion, toward the cooling unit from a rear side opening end portion that is provided above the cooling wind introducing hole, at a flow velocity that is faster than a flow velocity of the air flowing through the lower portion of the vehicle, wherein a portion of the cooling wind introducing passage is formed so as to extend-out toward a vehicle rear side, and the portion that is formed so as to extend-out is disposed between the shroud and the cooling wind introducing hole and so as to overlap the cooling wind introducing hole in a vertical direction of the vehicle.
