Abstract
A cooling system for a vehicle having a liquid-cooled engine is provided. The cooing system includes a heat exchanger constructed and arranged to be mounted in spaced relation with respect to the engine for cooling the liquid by air directed from a front side of the heat exchanger through a rear side of the heat exchanger. Duct structure is coupled to the rear side of the heat exchanger so as to cover at least a portion of the rear side, and to receive at least a portion of air exiting the rear side of the heat exchanger. The duct structure is mounted with respect to the heat exchanger so that a portion of the duct structure extends beyond bounds of a sidewall of the heat exchanger. At least one radial-flow type fan is mounted in the extending portion of duct structure such that air flowing through the heat exchanger and the duct structure is pulled by the fan so as to exit generally at the sidewall of the heat exchanger. A motor is operatively coupled to the fan to drive the fan.
