Abstract
A cooling unit that is cooled by heat exchange with air is disposed at a rear side in a vehicle longitudinal direction of a power unit. Further, a cooling fan is disposed at a rear in the vehicle longitudinal direction of the cooling unit. Further, catalytic converters are disposed at a rear side in the vehicle longitudinal direction of the power unit. A periphery of these catalytic converters is surrounded by a heat insulator. A duct portion, that communicates an interior of the heat insulator and a space between the cooling unit and the cooling fan is provided at this heat insulator.
Claims10
A vehicle front portion structure comprising:
- a power unit that is disposed in a power unit compartment provided at a vehicle front portion, and that includes an internal combustion engine that generates driving force that causes a vehicle to travel;
- a cooling unit that is disposed at a rear side in a vehicle longitudinal direction with respect to the power unit, and that is cooled by heat exchange with air;
- a fan that is disposed at a rear in the vehicle longitudinal direction of the cooling unit, and that, by being operated, generates cooling wind that passes through the cooling unit and is discharged to a vehicle exterior;
- an exhaust purifying device that is disposed at a rear side in the vehicle longitudinal direction with respect to the power unit, and that has a catalyst that purifies exhaust gas discharged from the internal combustion engine;
- a heat retaining member that surrounds a periphery of the exhaust purifying device, and in which is formed an air intake port that takes-in, into an interior, air that cools the exhaust purifying device;
- and
- a communication portion that communicates the interior of the heat retaining member and a space between the cooling unit and the fan.
