VEHICLE COOLING DEVICE
A vehicle cooling device includes a heat exchanger, an under cover, and a rear duct. The heat exchanger is arranged so as to be exposed to outside air that is taken into an inside of a vehicle from a front side of the vehicle and that flows backward. The under cover constitutes a lower wall surface of a front end portion of the vehicle. The under cover includes a front cover portion and a rear cover portion that can open and close an opening portion positioned on a rear side of the heat exchanger, and an actuator that drives opening and closing of the front cover portion and the rear cover portion. The rear duct is provided on a rear side of the heat exchanger, and guides, to the opening portion of the under cover, outside air that passes through the heat exchanger.
1 . A vehicle cooling device comprising:
a heat exchanger arranged so as to be exposed to outside air that is taken into an inside of a vehicle from a front side of the vehicle and that flows backward;
an under cover constituting a lower wall surface of the vehicle, and including a cover portion that can open and close an opening portion positioned on a rear side of the heat exchanger, and a driving device that drives opening and closing of the cover portion; and
a rear duct being provided on a rear side of the heat exchanger and guiding, to the opening portion of the under cover, outside air that passes through the heat exchanger.
2 . The vehicle cooling device according to claim 1 , further comprising a flow rate adjusting device being provided on a front side of the heat exchanger and adjusting a flow rate of outside air taken into the inside of the vehicle from the front side of the vehicle.
3 . The vehicle cooling device according to claim 2 , further comprising a front duct being provided between the flow rate adjusting device and the heat exchanger and guiding, to a front surface of the heat exchanger, outside air that passes through the flow rate adjusting device.
4 . The vehicle cooling device according to claim 1 , wherein
the cover portion includes a front cover portion rotatable around a shaft portion extending in a vehicle width direction at a front end portion of the opening portion, and,
in a state where the opening portion is opened, a distal end portion of the front cover portion is oriented to a lower end of the heat exchanger.
5 . The vehicle cooling device according to claim 2 , wherein
the cover portion includes a front cover portion rotatable around a shaft portion extending in a vehicle width direction at a front end portion of the opening portion, and,
in a state where the opening portion is opened, a distal end portion of the front cover portion is oriented to a lower end of the heat exchanger.
6 . The vehicle cooling device according to claim 3 , wherein
the cover portion includes a front cover portion rotatable around a shaft portion extending in a vehicle width direction at a front end portion of the opening portion, and,
in a state where the opening portion is opened, a distal end portion of the front cover portion is oriented to a lower end of the heat exchanger.
