Abstract
A tractor vehicle having an engine in a heat and sound controlling enclosure. A plurality of access apertures are provided therein including a pair or evacuation apertures for allowing the passage of heated air out from the enclosure. A second enclosure through which a flow of ambient air is drawn has an air intake and filter and a plurality of heat exchanging units housed therein. A flow inducing fan draws air through the chamber and the heat exchangers and directs it directly out the front grille of the vehicle.
Claims8
In a tractor vehicle having a frame to which the vehicle engine and the engine coolant heat exchanger are mounted, a chambered engine compartment comprising:
- a first enclosure surrounding the vehicle engine having an opened bottom and a plurality of apertures including a muffler shroud accompanying aperture and an exhaust duct accompanying aperture;
- a second enclosure housing an engine coolant heat exchanger;
- an engine driven fan located outboard of said heat exchanger for drawing air through said second enclosure housing and through said heat exchanger;
- an exhaust duct having a first end connected to said exhaust duct accompanying aperture and a second end located on the fan side of said heat exchanger between said heat exchanger and said fan whereby said fan may draw air from said duct and propel it forward out the front of said tractor vehicle.
In a tractor vehicle having a frame to which the vehicle engine and the engine coolant heat exchanger are mounted, a chambered engine compartment comprising:
- a first enclosure having a rear wall, a front wall, a top panel having a plurality of apertures, and left and right side panels arranged to form an insulated sound attenuating enclosure around said vehicle engine;
- a second enclosure having a hood panel, left and right aperture equipped side panels, a back end panel, and first and second bottom panels arranged to form an enclosure housing said engine coolant heat exchanger;
- an engine driven fan located outboard of said heat exchanger for drawing air through said second enclosure housing and through said heat exchanger;
- an exhaust duct having a first end for receiving air from one of said apertures of said first enclosure, and the exhaust duct having a second end located on the outboard side of said heat exchanger whereby said fan may draw air through said duct from said first enclosure;
- a muffler shroud placed above a second of said apertures of said first enclosure enabling heated air in said first enclosure a path of escape through convection phenomena.
