ENGINE COOLING SYSTEM FOR SKID STEER LOADERS

摘要

ENGINE COOLING SYSTEM FOR SKID STEER LOADERS A skid steer loader (10) includes an engine compartment (22) and a heat exchanger compartment (24) located behind the operator's compartment (40). A fan shroud (240) mounted between the heat exchanger compartment (24) and the engine compartment (22) has a first air intake aperture (248) opening into the heat exchanger compartment (24), a second air intake aperture (241) opening into the engine compartment (22), and an exhaust port (254). A double-bladed radial fan (242) is mounted for rotation within the fan shroud (240) between the first and second air intake apertures. A fan drive mechanism (244) coupled to the engine (142) rotates the fan (242). The fan (242) simultaneously induces a heat exchanger airflow of ambient air through the heat exchanger compartment (24) and into the fan shroud (240) through the first air intake aperture (248), and an engine compartment evacuation airflow from within the engine compartment (22) into the fan shroud (240) through the second air intake aperture (241). The heat exchanger airflow and engine compartment evacuation airflows are mixed and jointly discharged from the loader (10) through the exhaust port (254).
