Ventilation for electric generator system
In the disclosure herein, an electric generator system is shown and comprises a housing assembly, an electric generator positioned within the housing assembly, an engine positioned within the housing assembly and operatively coupled to the electric generator, a muffler assembly positioned within the housing assembly, and a dividing plate positioned between the engine and the muffler assembly. Exemplary embodiments include an engine fan positioned within the housing and driven by the engine with an engine fane inlet opening formed radially around the engine fan.
1. An electric generator system comprising:
a housing assembly including a pan;
an electric generator positioned within the housing assembly;
an engine positioned within the housing assembly and operatively coupled to the electric generator;
a muffler assembly positioned within the housing assembly;
a dividing plate positioned between the engine and the muffler assembly and flush with the pan and extending upwardly from the pan; and
an engine fan positioned between the engine and the dividing plate.
2. The generator system of claim 1 wherein:
an engine fan outlet opening positioned on the dividing plate.
3. The generator system of claim 2 further comprising:
an engine fan inlet opening formed radially around the engine fan.
4. The generator system of claim 2 further comprising:
an engine fan outlet opening formed through the dividing plate.
5. The generator system of claim 1 further comprising:
an inlet vent opening positioned on the housing; and
wherein the engine fan draws ambient air into the housing through the inlet vent opening and into the engine fan inlet opening, exhausting the ambient air out of the engine fan outlet opening.
6. The generator system of claim 5 wherein:
the engine fan outlet opening is positioned to force ambient air from the inlet vent over the muffler.
7. The generator system of claim 1 further comprising:
a cooling duct formed in the dividing plate.
8. The generator system of claim 1 further comprising:
thermally insulating material positioned on the dividing plate.
9. The generator system of claim 1 further comprising:
a muffler bellow which passes through the dividing plate.
10. The generator system of claim 1 wherein:
the dividing plate is sized and positioned to be flush with corresponding interior surfaces of the housing.
11. The generator system of claim 1 wherein:
an engine fan outlet opening and an engine fan inlet opening which are positioned on opposite sides of the dividing plate.
12. An electric generator system comprising:
a housing assembly;
an electric generator positioned within the housing assembly;
an engine positioned within the housing assembly and operatively coupled to the electric generator;
a muffler assembly positioned within the housing assembly;
a dividing plate positioned vertically between the engine and the muffler assembly;
an engine fan having an outlet opening that passes through the dividing plate; and
a bellow extending from the muffler and passing horizontally through the dividing plate to connect with the engine.
13. The generator system of claim 12 further comprising:
an engine fan inlet opening formed radially around the engine fan.
14. The generator system of claim 12 further comprising:
an engine fan outlet opening formed through the dividing plate.
15. The generator system of claim 12 further comprising:
a muffler bellow which passes through the dividing plate.
16. The generator system of claim 12 wherein:
the dividing plate is sized and positioned to be flush with corresponding interior surfaces of the housing.
17. The generator system of claim 12 wherein:
an engine fan outlet opening and an engine fan inlet opening which are positioned on opposite sides of the dividing plate.
