Abstract

A system and method for reducing fouling. In one embodiment, the system includes a housing and a plurality of channels contained within the housing. The system also includes a fouling reduction element that passes through at least one channel of the plurality of channels, wherein the fouling reduction element is movable such that it reduces fouling inside of the at least one channel. According to the system and method disclosed herein, the fouling reduction element efficiently cleans the inside of the channels of the cooling system.

Claims (28)

1. An engine cooling system comprising:

a housing;

a plurality of channels contained within the housing; and

a fouling reduction element that passes through at least one channel of the plurality of channels, wherein the fouling reduction element is movable such that it reduces fouling inside of the at least one channel,

wherein the fouling reduction element is a wire that is longer than the at least one channel and extends out of the at least one channel at both ends of the at least one channel to form extended portions, at least one of the extended portions of the wire being bent to form a bent end extending transverse to a longitudinal axis of the at least one channel, said bent end having a length greater than a diameter of said at least one channel to provide a stop to prevent the fouling reduction element from coming out of the at least one channel.

2. The system of claim 1 wherein the fouling reduction element moves within the at least one channel and against inside of walls of the at least one channel to remove deposits from the walls.

3. The system of claim 1 wherein the fouling reduction element moves within the at least one channel in response to engine vibration.

4. The system of claim 1 wherein the fouling reduction element moves within the at least one channel in response to exhaust gas.

5. The system of claim 1 wherein the fouling reduction element is a wire.

6. The system of claim 1 wherein the fouling reduction element is a wire that is longer than the at least one channel and that extends out of the at least one channel at both ends of the at least one channel.

7. A vehicle comprising:

an engine; and

an engine cooling system coupled to the engine, the engine cooling system comprising:

a housing;

a plurality of channels contained within the housing; and

a fouling reduction element that passes through at least one channel of the plurality of channels, wherein the fouling reduction element is movable such that it reduces fouling inside of the at least one channel,

wherein the fouling reduction element is a wire that is longer than the at least one channel and extends out of the at least one channel at both ends of the at least one channel to form extended portions, at least one of the extended portions of the wire being bent to form a bent end extending transverse to a longitudinal axis of the at least one channel, said bent end having a length greater than a diameter of said at least one channel to provide a stop to prevent the fouling reduction element from coming out of the at least one channel.

8. The vehicle of claim 7 wherein the fouling reduction element moves within the at least one channel and against inside of walls of the at least one channel to remove deposits from the walls.

9. The vehicle of claim 7 wherein the fouling reduction element moves within the at least one channel in response to engine vibration.

10. The vehicle of claim 7 wherein the fouling reduction element moves within the at least one channel in response to exhaust gas.

11. The vehicle of claim 7 wherein the fouling reduction element is a wire.

12. The vehicle of claim 7 wherein the fouling reduction element is a wire that is longer than the at least one channel and that extends out of the at least one channel at both ends of the at least one channel.

13. A method comprising:

providing a fouling reduction element; and

inserting the fouling reduction element into at least one channel of a plurality of channels, wherein the fouling reduction element is movable such that it reduces fouling inside of the at least one channel,

wherein the fouling reduction element is a wire that is longer than the at least one channel and extends out of the at least one channel at both ends of the at least one channel to form extended portions, at least one of the extended portions of the wire being bent to form a bent end extending transverse to a longitudinal axis of the at least one channel, said bent end having a length greater than a diameter of said at least one channel to provide a stop to prevent the fouling reduction element from coming out of the at least one channel.

14. The method of claim 13 wherein the fouling reduction element moves within the at least one channel and against inside of walls of the at least one channel to remove deposits from the walls.

15. The method of claim 13 wherein the fouling reduction element is a wire.
