Abstract:
A cooling system for a compact vehicle such as a compact loader having an engine and an engine compartment, includes a single axial flow fan that is surrounded by a shroud and has a high pressure side and a low pressure side. Air flow generated by the fan is used for cooling components of the compact vehicle and exhausting heated air from a second shroud. Auxiliary openings are provided between the engine compartment and the shrouds to provide air flow between the engine compartment and one or both of the shrouds when the fan is rotating. The motor driving the fan is reversible.
