US 10,100,579 B2 · Exhaust assembly cooling system

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.

Dependent claims

A system comprising:

a compartment having an external surface and comprising:
an engine area;
an exhaust area bounded in part by a portion of the compartment's external surface containing plural air openings that permit ambient air to enter and freely circulate within the exhaust area;
a radiator area;
a first barrier that reduces convection and conduction of heat between the engine and exhaust areas and the radiator area;
and
a second barrier that restricts flow of air from the engine area into the exhaust area;
an engine situated within the engine area;
an exhaust system situated within the exhaust area and configured to purify and vent exhaust produced by the engine;
a radiator situated within the radiator area;
a fan assembly within the compartment and configured to produce airflow through the radiator area;
and
a conduit interconnecting the fan with the exhaust area without communicating with the radiator area.
