ABSTRACT:
The electrical generator set has two separate cooling airflows. A first airflow is generated by an impeller mounted on the drive shaft of the engine and provides for cooling the electrical generator or alternator and for partial cooling of the electrical circuitry which controls mainly the voltage of the electrical output. This airflow exists only while the engine is running. The first airflow is mixed with the exhaust gases of the internal combustion engine for noise and temperature reduction. the use of a venturi tube supports driven by the exhaust gases supports the airflow.
A second airflow provides for cooling the radiator of the liquid cooled internal combustion engine and for partial cooling for the electrical circuitry. This second airflow is generated by one or more electrical fans and is independent on whether or not the engine is running.
