Abstract:
A cooling system assembly for an off-road vehicle having an engine surrounded at least in part by an engine enclosure, said cooling system assembly comprising:a heat exchanger coupled to the engine for cooling the engine, said heat exchanger having an air intake face and an air discharge face;a radial fan positioned between the engine and the heat exchanger, said fan operably connected to the air discharge face of the heat exchanger for drawing air axially from around the engine as well as through the heat exchanger, and exhausting the air radially;said engine enclosure including an end face lying substantially in a plane disposed substantially perpendicular to a longitudinal axis of the vehicle and first and second side faces, each of said first and second side faces lying substantially in a plane disposed substantially parallel to the longitudinal axis of the vehicle; andsaid enclosure having a screened air intake forming a grille located at least partially on the end face and each of the first and second side faces, an inner wall forming a baffle aligned with at least one of the faces, and sidewalls adjacent the air intake and the baffle for forming a substantially gastight passage therebetween for directing air from the air intake to the heat exchanger air intake face.
