Abstract
A compact utility machine, such as a compact track loader or wheel loader, a compact telehandler, or a compact trencher, implements a passive cooling system. The passive cooling system may establish a negative pressure zone within the machine's engine compartment to draw ambient air into the engine compartment for cooling various components. The negative pressure zone may be defined upstream with respect to an exhaust fan that pushes air out of the engine compartment. A pressure differential is defined between the ambient air and the negative pressure zone, which drives air into the engine compartment through an air inlet(s) in an engine compartment side wall(s). A hydraulic oil cooler may be mounted inside of the engine compartment, overlying one of the engine compartment's air intakes.
