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 cooling system comprising:
a radiator; a fan configured to generate an air flow path for the radiator; and a cooling pipe positioned between the fan and the radiator, wherein the air flow path flows from the fan to the radiator across the cooling pipe.

2 . The cooling system of claim 1 , further comprising:
a turbocharger; and an intake manifold, wherein the cooling pipe extends between the turbocharger and the intake manifold.

3 . The cooling system of claim 2 , wherein the cooling pipe is parallel to a line from the turbocharger to the intake manifold.

4 . The cooling system of claim 1 , wherein the cooling pipe is a predetermined color.

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

6 . The cooling system of claim 1 , wherein the cooling pipe is positioned at a location that intersects a line between the fan and the radiator.

7 . The 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.

8 . The 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 cooling system of claim 1 , further comprising:
an air pipe configured to support the cooling path, wherein air flows through the air pipe

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

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

12 . An engine comprising:
a turbocharger; a radiator; an intake manifold; and a passive cooling system including:
a fan configured to generate an air flow path for the radiator; and
a cooling pipe positioned between the fan and the radiator and coupled to the turbocharger and the intake manifold,
wherein the air flow path flows from the fan to the radiator across the cooling pipe.

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

14 . The engine of claim 12 , wherein the cooling pipe is substantially parallel to a path from the turbocharger to the intake manifold.

15 . The engine of claim 12 , wherein the cooling pipe extends in a first direction from the turbocharger toward the cooling system, and a second direction perpendicular to the first direction.

16 . The engine of claim 12 , further comprising:
a controller configured to receive data indicative of an operation of an engine or generator and compare the data indicative of the operation of the engine or generator to a threshold.

17 . The engine of claim 16 , wherein the controller is configured to generate a valve command in response to the comparison.

18 . A method for manufacturing a cooling system for an engine, the method comprising:
providing a fan configured to generate an air flow path for a radiator; and coupling one or more cooling pipes to the engine in a position between the fan and the radiator, wherein the air flow path flows from the fan to the radiator across the one or more cooling pipes.

19 . The method of manufacturing of claim 18 , wherein the one or more cooling pipes includes a first cooling pipe having a first path length across a diameter of the fan and a second cooling pipe having a second path length across the diameter of the fan.

20 . The method of manufacturing of claim 18 , wherein the one or more cooling pipes includes a plurality of cooling pipes.
