Abstract
An engine cooling system comprising an exhaust enclosure formed in an engine compartment of a work machine. An exhaust processing system is situated within the exhaust enclosure. The exhaust enclosure is bounded in part by spaced upper and lower panels that are exposed to the ambient environment. At least one opening is formed in each panel. When an engine and fan also contained within the engine compartment are shut down, ambient air flows into the exhaust enclosure through the opening in the lower panel. The air flows around the exhaust processing system and back into the ambient environment through the opening formed in the upper panel.
Claims22
A self-propelled machine situated in an ambient environment, comprising:
- an engine compartment housing an engine and an exhaust processing system;
- in which the engine is configured to propel the machine;
- in which the exhaust processing system is in fluid communication with the engine and is configured to chemically treat the engine's exhaust and generate a treated fluid stream;
- and
- an exhaust stack in fluid communication with the exhaust processing system and discharging into the ambient environment;
- in which the engine compartment comprises an exhaust enclosure that contains the exhaust processing system, the exhaust enclosure bounded by spaced and opposed upper and lower panels, each of said panels exposed to the ambient environment and having at least one opening formed therein, the openings distinct from any opening associated with the exhaust stack and situated along an airflow path that extends through the exhaust enclosure.
A system, comprising:
- a drill rig situated in an ambient environment, comprising:
- an engine compartment housing an engine and an exhaust processing system;
- in which the engine is configured to propel the drill rig;
- in which the exhaust processing system is in fluid communication with the engine and is configured to chemically treat the engine's exhaust and generate a treated fluid stream;
- and
- in which the engine compartment comprises an exhaust enclosure that contains the exhaust processing system, the exhaust enclosure bounded by spaced and opposed upper and lower panels, each of said panels exposed to the ambient environment and having at least one opening formed therein;
- and
- air from the ambient environment flowing into the exhaust enclosure through the opening formed in the lower panel, flowing around the exhaust processing system, and flowing out of the exhaust enclosure and back into the ambient environment through the opening formed in the upper panel.
A self-propelled machine situated in an ambient environment, comprising:
- an engine configured to propel the machine;
- an exhaust processing system in fluid communication with the engine and configured to chemically treat the engine's exhaust and generate a treated fluid stream;
- an exhaust stack in fluid communication with the exhaust processing system and discharging into the ambient environment;
- and
- an exhaust enclosure that contains the exhaust processing system, the exhaust enclosure bounded by spaced upper and lower panels, each of said panels exposed to the ambient environment and having at least one opening formed therein, the openings distinct from any opening associated with the exhaust stack and situated along an airflow path that extends through the exhaust enclosure;
- in which the exhaust enclosure comprises a plurality of side walls positioned intermediate the upper and lower panels, in which each of the plurality of side walls comprises a heat insulating material.
