Abstract
Systems, methods and apparatus for noise attenuation of a generator set are disclosed. The generator set includes an internal combustion engine enclosed within a compartment that substantially isolates the internal combustion from ambient air and a load connected to the internal combustion engine. A heat exchanger is disposed within or coupled to the compartment and is operable to cool air in the compartment without directly exchanging ambient air with compartment air.
Claims23
An apparatus, comprising:
- a liquid cooled internal combustion engine enclosed within a compartment, wherein an air intake of the internal combustion engine and an exhaust outlet of the internal combustion engine extend through the compartment for fluid communication with ambient air external to the compartment;
- a radiator located external to the compartment, wherein the cooling liquid of the engine is coupled through the compartment by plumbing extending through the compartment for circulation of cooling liquid therebetween, where the radiator is operable to exchange engine heat from the engine cooling fluid to ambient air from outside the compartment;
- a load, disposed outside of the compartment, mechanically coupled to the internal combustion engine;
- and
- a heat exchanger, wherein the heat exchanger is operable to exchange heat from air in the compartment with a cooling fluid, wherein the cooling fluid is isolated from the air in the compartment.

A system, comprising:
- a liquid cooled internal combustion engine and a generator operably coupled to the internal combustion engine;
- a compartment enclosing the internal combustion engine with the generator disposed outside the compartment;
- a radiator, disposed outside the compartment, that is in fluid communication with the cooling liquid of the internal combustion engine;
- wherein the internal combustion engine includes an air intake and an exhaust outlet extending through the compartment, the air intake and exhaust outlet being in fluid communication with ambient air outside of the compartment;
- and
- a heat exchanger system, wherein the heat exchanger system exchanges heat from air in the compartment with ambient air outside the compartment utilizing a cooling fluid passing through the heat exchanger system without exchanging air in the compartment with ambient air outside of the compartment.
3 more elements
A method, comprising:
- positioning a liquid cooled internal combustion engine within a compartment, the internal combustion engine being mechanically coupled to a load disposed outside of the compartment;
- operating the liquid cooled internal combustion engine;
- mechanically transferring power from the internal combustion engine to the load to power the load;
- and
- cooling air in the compartment with a heat exchanger located in the compartment, wherein the heat exchanger exchanges heat from air in the compartment with a cooling fluid passing through the heat exchanger without exchanging air in the compartment with ambient air.
