Abstract
A tractor vehicle (10) is provided with segregated engine (45) and heat exchanger compartments (64). The heat exchanger compartment (64) is supplied with ambient air from an intake grille (24) above the heat exchanger compartment. The process air from the heat exchanger compartment is exhausted forwardly through a front grille (40) location on the tractor. The engine compartment is ventilated by a forced air system induced by the heat exchanger compartment exhaust fan (80). Engine compartment process air is drawn to the downstream side of the primary heat exchanger (76) and is discharged along with the heat exchanger compartment process air, through the front grille of the tractor.
