Abstract

Claims (55)

1. A standby generator, comprising:

an engine including an output shaft;

an alternator;

an enclosure comprising:

a base; and

a plurality of walls extending from the base comprising a front wall, a rear wall, a first wall, and a second wall;

a first intake opening configured to allow air to be drawn into the enclosure; and

an exhaust opening configured to allow heated air and exhaust gases to be expelled from the enclosure;

wherein the first intake opening is provided on the rear wall proximate the first wall and the exhaust opening is provided on the front wall proximate the second wall;

wherein the air drawn into the enclosure at the first intake opening directly flows over the engine and is expelled through the exhaust opening.

2. The standby generator of claim 1 , further comprising:

a second intake opening provided on the rear wall configured to allow air to be drawn into the enclosure.

3. The standby generator of claim 2 , wherein the first intake opening is configured to allow air to be drawn into the engine and wherein the second intake opening is configured to allow air to be drawn into the enclosure to cool the alternator.

4. The standby generator of claim 3 , wherein the first intake opening and the second intake opening are positioned on opposite sides of the rear wall.

5. The standby generator of claim 3 , wherein the second intake opening is positioned proximate the first wall.

6. The standby generator of claim 3 , wherein the exhaust opening is positioned proximate the first wall.

7. The standby generator of claim 3 , wherein the first intake opening and the second intake opening draw air into the enclosure in the same direction as an expulsion of exhaust gases from the exhaust opening.

8. A standby generator, comprising:

an engine including an output shaft;

an alternator

a base;

a first pair of opposing walls coupled to the base comprising:

a front wall; and

a rear wall;

a second pair of opposing walls coupled to the base comprising:

a first wall; and

a second wall;

a first intake opening in the rear wall proximate the first wall and configured to draw air into the generator; and

an exhaust opening positioned in the front wall proximate the second wall and configured to expel exhaust gases and heated air from the generator;

wherein the air drawn into the enclosure at the first intake opening directly flows over the engine and is expelled through the exhaust opening.

9. The standby generator of claim 8 , wherein the second pair of opposing walls does not include the first intake opening or the exhaust opening.

10. The standby generator of claim 9 , further comprising a second intake opening positioned in the rear wall configured to draw air into the generator.

11. The standby generator of claim 10 , wherein the first intake opening is configured to draw air into the generator to cool the engine and wherein the second intake opening is configured to draw air into generator to cool the alternator.

12. The standby generator of claim 11 , wherein the first intake opening and the second intake opening are positioned on opposite sides of the rear wall.

13. The standby generator of claim 12 , wherein the first intake opening and the second intake opening draw air into the enclosure in the same direction as an expulsion of exhaust gases from the exhaust opening.

14. The standby generator of claim 13 , further comprising:

an engine intake duct configured to route air entering the first intake opening to the engine;

an alternator intake duct configured to route air entering the second intake opening to the alternator; and

a muffler exhaust duct configured to route exhaust gases from the engine to the exhaust opening.

15. A standby generator, comprising:

an engine including an output shaft;

an alternator;

an enclosure comprising:

a base; and

a plurality of walls extending from the base comprising a front wall, a rear wall, a first wall, and a second wall;

a first intake opening provided on the rear wall and configured to allow air to be drawn into the enclosure; and

an exhaust opening provided on the front wall and configured to allow heated air and exhaust gases to be expelled from the enclosure;

wherein the first intake opening is positioned proximate the engine and the exhaust opening is positioned proximate the alternator;

wherein the air drawn into the enclosure at the first intake opening directly flows over the engine and is expelled through the exhaust opening.

16. The standby generator of claim 15 , further comprising:

a second intake opening provided on the rear wall configured to allow air to be drawn into the enclosure.

17. The standby generator of claim 16 , wherein the first intake opening is configured to allow air to be drawn into the engine and wherein the second intake opening is configured to allow air to be drawn into the enclosure to cool the alternator.

18. The standby generator of claim 17 , wherein the first intake opening and the second intake opening are positioned on opposite sides of the rear wall.

19. The standby generator of claim 17 , wherein the first intake opening is positioned proximate the second wall and the second intake opening is positioned proximate the first wall.

20. The standby generator of claim 17 , wherein the first intake opening and the second intake opening draw air into the enclosure in the same direction as an expulsion of exhaust gases from the exhaust opening.
