ABSTRACT:
A cooling system for a machine is provided. The machine has an operator compartment, a front end, and an engine cooled by a first heat exchanger and mounted within an engine compartment. The engine compartment is positioned behind the operator compartment in relation to the front end. A fan is mounted within the engine compartment and has an inlet and a first and a second outlet. A second heat exchanger is fluidically coupled to the fan and the engine and mounted within the engine compartment. A first fluid flow path extends from ambient to the inlet. A second fluid flow path extends from the first outlet to ambient and extends through the second heat exchanger. A third fluid flow path extends from the second outlet to ambient and extends through the first heat exchanger, and is thermally isolated from the second fluid flow path.
