  • Exhaust assembly cooling system
    Patent number: 10100579
    Abstract: A system for cooling an exhaust system of a construction machine. The system has a compartment within which the exhaust system is contained. A first compartment wall forms an external boundary of the compartment and has a plurality of air inlets proximate the exhaust system. A fan assembly is also within the compartment and separated from the exhaust system by a barrier. A conduit crosses the barrier and has an inlet near the exhaust system and an outlet positioned between the barrier and the fan assembly. Air flows within the compartment along an air flow path that extends from the air inlets, around the exhaust system, through the conduit and into the fan assembly. The air flow path extends from the fan assembly through a plurality of air outlets formed in an external compartment wall.
