Abstract
A vehicle front portion structure is obtained that can efficiently lead cooling wind to a heat exchanger. A vehicle front portion structure has: a heat exchanger; a flow path member that forms a discharging flow path that discharges airflow, that has passed through an air-side flow path of the heat exchanger, to a vehicle exterior from a downwardly-directed opening portion at a rear side with respect to the heat exchanger; and an airflow promoting structure that forms a contracted flow path that gradually becomes more narrow from a front end side toward a rear end side, and that, at the front end side, increases a speed of traveling wind that has flowed-in from beneath a vehicle floor, and that causes the traveling wind to flow-out from between the heat exchanger and the opening portion at the discharging flow path.
Claims4
A vehicle front portion structure comprising:
- a heat exchanger that is disposed at a vehicle rear side with respect to a power unit, and into which airflow is introduced through an air intake port beneath a vehicle floor;
- a flow path member that forms a discharging flow path that discharges airflow, that has passed through an air-side flow path of the heat exchanger, to a vehicle exterior from an opening portion that is directed toward a vehicle lower side at the vehicle rear side with respect to the heat exchanger;
- and
- an airflow promoting structure that is disposed between the heat exchanger and the opening portion, and at a vehicle lower side of the discharging flow path, a traveling wind flowing-out without passing through the air-side flow path of the heat exchanger and that forms a contracted flow path that gradually becomes more narrow from a front end side toward a rear end side, and that, at the front end side, increases a speed of traveling wind that has flowed-in from beneath the vehicle floor, and that causes the traveling wind to flow-out from between the heat exchanger and the opening portion at the discharging flow path.
