2094040 9208042 PCTABS00013 A reduced noise modular cooling system (10) for a large engine powered off-road machine formed of a modular superstructure (36) mountable on and removable as a unit from a machine, air cooled radiator portions (50, 52, 54) affixed to the superstructure front and opposed sides, a floor and hood closing the superstructure top (56) and bottom (58) and a fan panel (60) closing the superstructure rear, the panel having one or preferably two fan shroud openings (92, 94) therein, thereby forming a plenum chamber (62) within the interior of the superstructure (36), a fan rotatably (88, 90) supported by the superstructure (36) within each of the fan shroud openings (92, 94) and a drive shaft (76, 78) extending from the machine engine for driving each of the fans (88, 90) to evacuate air from the plenum chamber (62) and thereby to cause air to flow through the radiator portions (50, 52, 54) and couplings for connecting fluid circulation through the radiator portions to the vehicle engine. Noise reduction is achieved by the increased radiator area accomplished by the wrap-around radiator portions which extend at least on three sides of the plenum formed in the superstructure, and by providing space to operate two smaller fans at a slower speed compared to one single large fan.
