Abstract
The engine generator set has an internal combustion engine and an alternator in a main compartment. Two separate cooling air streams independently cool the internal combustion engine and alternator. The independent air streams are then intermixed in the main compartment and used to cool the engine exhaust system and gases. Heat sensitive components are segregated from the heat generating components. Cooling air is drawn over the heat sensitive components maintaining them at nearly ambient temperature.
Claims12
An internal combustion engine generator set comprising:
- a housing having an inlet end, an outlet end, and a main compartment, said main compartment having an inlet at said inlet end of said housing;
- an external cooling air passageway having an inlet and an outlet, said inlet of said passageway being at said inlet end of said housing, said outlet of said passageway exhausting cooling air into said main compartment at said housing outlet end;
- an alternator mounted in said main compartment at said outlet end of said housing, said alternator having a rotatable shaft and frame supported by an inlet end bracket and an outlet end bracket;
- said brackets having apertures, said outlet of said passageway communicatively connected to said inlet end bracket of said alternator;
- an alternator cooling fan mounted on said rotatable shaft, said alternator cooling fan interposed between said alternator and said internal combustion engine;
- whereby said alternator cooling fan draws alternator cooling air into said passageway at said inlet end of said housing, through said passageway into said inlet end bracket and through said frame, and then expels said alternator cooling air into said main compartment of said housing;
- an internal combustion engine mounted in said main compartment at said inlet end of said housing, said internal combustion engine having a drive shaft, said drive shaft having a first end and a second end, said first end of said drive shaft being coupled to rotate said shaft of said alternator;
- and
- an engine cooling fan mounted for rotation by said drive shaft and positioned adjacent to said inlet of said main compartment to draw engine cooling air through said inlet of said main compartment and force said engine cooling air past said internal combustion engine into said main compartment of said housing to mix with said alternator cooling air.
