Abstract

A passive cooling system includes a fan configured to generate an air flow path for a radiator, the air flow path extending from the fan to the radiator and a cooling pipe extended between a turbocharger and an intake manifold, the cooling path positioned in the air flow path between the fan and the radiator.

First claim

We claim:

1. A passive cooling system comprising:
a fan configured to generate an air flow path for a radiator, the air flow path extending from the fan to the radiator; and
a cooling pipe having a shape to follow, at least in part, a perimeter of the fan and extended between a turbocharger and an intake manifold, the cooling pipe positioned in the air flow path between the fan and the radiator.

2. The passive cooling system of claim 1 , wherein the cooling pipe is aluminum.

3. The passive cooling system of claim 1 , wherein the cooling pipe extends in a direction perpendicular to the air flow path.

4. The passive cooling system of claim 1 , wherein the cooling pipe is parallel to a line from the turbocharger to the intake manifold.

5. The passive cooling system of claim 1 , wherein the cooling pipe extends in a curved shape.

6. The passive cooling system of claim 1 , wherein the cooling pipe extends in a first direction from the turbocharger toward the passive cooling system, and a second direction perpendicular to the first direction.

7. The passive cooling system of claim 1 , wherein the cooling pipe is U-shaped.

8. The passive cooling system of claim 1 , further comprising:
a turbine located in an exhaust duct; and
a compressor rotationally coupled to the turbine and configured to force air through the cooling pipe.

9. The passive cooling system of claim 1 , further comprising:
a frame including one or more openings to support the cooling pipe.

10. The passive cooling system of claim 9 , wherein a vertical plate of the frame supports the cooling pipe and the fan.

11. An engine comprising:
a turbocharger;
an intake manifold; and
a passive cooling system including:
a fan configured to generate an air flow path for a radiator; and
a cooling pipe having a shape to follow, at least in part, a perimeter of the fan and extended between a turbocharger and an intake manifold, the cooling pipe positioned in the air flow path between the fan and the radiator.

12. The engine of claim 11 , wherein the cooling pipe extends in a direction perpendicular to the air flow path.

13. The engine of claim 11 , wherein the cooling pipe is substantially parallel to a path from the turbocharger to the intake manifold.

14. The engine of claim 11 , wherein the cooling pipe extends in a curved shape.

15. The engine of claim 11 , wherein the cooling pipe extends in a first direction from the turbocharger toward the passive cooling system, and a second direction perpendicular to the first direction.

16. The passive cooling system of claim 1 , further comprising:
a frame including one or more openings to support the cooling pipe, wherein one or more openings in the frame supports the cooling pipe and the fan.

17. A method for operating a dynamic cooling system, the method comprising:
receiving data indicative of an operation of an engine or generator;
comparing the data indicative of the operation of the engine or generator to a threshold;
generating a valve command in response to the comparison; and
providing the valve command to a valve system including a plurality of valves to open or close a plurality of cooling pipes associated with a plurality of cooling paths having different shapes.

18. The method of claim 17 , wherein the plurality of cooling pipes includes a first cooling pipe having a first path length across a diameter of a fan and a second cooling pipe having a second path length across the diameter of the fan.

19. The method of claim 18 , wherein the first cooling pipe and the second cooling pipe are positioned between the fan and a radiator.

20. The method of claim 17 , wherein at least one of the plurality of cooling pipes has a shape that follows a perimeter of a fan.
