Abstract

An air cooling system includes an intake line, a heat exchanger, an exhaust line, and an amount of frozen carbon dioxide. The intake line connects the heat exchanger to an air source, and the exhaust line connects the heat exchanger to an air destination. The frozen carbon dioxide is disposed against at least a portion of the heat exchanger to draw heat away from the air. Optionally, a system can include dual heat exchangers connected via a bridge line, with the frozen carbon dioxide being disposed there between.

Claims

1. An air cooling system, said system comprising:

an intake line connected to an air source, said intake line for carrying the air from the air source;

a heat exchanger having an exterior surface, said heat exchanger being connected to said intake line;

an exhaust line connected to said heat exchanger, said exhaust line for carrying the air away from said heat exchanger to an air destination; and

an amount of frozen carbon dioxide disposed against at least a portion of the exterior surface of said heat exchanger to transfer heat away from the air.

2. The system of claim 1, said system further comprising:

a housing having a lid, an intake aperture, and an exhaust aperture;

wherein said housing surrounds said heat exchanger and said amount of frozen carbon dioxide, said intake line connects to said heat exchanger via the intake aperture, said exhaust line connects to said heat exchanger via the exhaust aperture, and the lid is closely openable to receive said amount of frozen carbon dioxide.

3. The system of claim 2, wherein said housing is at least substantially air-tight and said housing includes a valve for releasing air pressure from within said housing.

4. The system of claim 3, wherein the valve releases at least a portion of the air pressure from within said housing if the air pressure exceeds a predetermined amount.

5. The system of claim 2, wherein said housing further surrounds at least one holding element that limits said amount of frozen carbon dioxide from moving in at least one direction.

6. The system of claim 5, wherein the at least one holding element is formed, at least in part, from a foam material.

7. The system of claim 1, wherein said heat exchanger includes a plurality of fins, and said amount of frozen carbon dioxide is disposed against at least one of the plurality of fins.

8. The system of claim 1, wherein the destination is a combustion chamber.

9. An air cooling system, said system comprising:

an intake line connected to an air source, said intake line for carrying air from the air source;

a first heat exchanger having a first heat exchanger exterior surface, said first heat exchanger being connected to said intake line;

a second heat exchanger having a second heat exchanger exterior surface, said second heat exchanger being connected to said first heat exchanger via a bridge line;

an exhaust line connected to said second heat exchanger, said exhaust line for carrying the air away from said second heat exchanger to an air destination; and

an amount of frozen carbon dioxide disposed against at least a portion of the first heat exchanger exterior surface and at least a portion of the second heat exchanger exterior surface to transfer heat away from the air.

10. The system of claim 9, said system further comprising:

a housing having a lid, an intake aperture and an exhaust aperture;

wherein said housing surrounds said first and second heat exchangers and said amount of frozen carbon dioxide, said intake line connects to said first heat exchanger via the intake aperture, said exhaust line connects to said second heat exchanger via the exhaust aperture, and the lid is closely openable to receive said amount of frozen carbon dioxide.

11. The system of claim 10, wherein said housing is at least substantially air-tight and said housing includes a valve for releasing air pressure from within said housing.

12. The system of claim 11, wherein the valve releases at least a portion of the air pressure from within said housing if the air pressure exceeds a predetermined amount.

13. The system of claim 10, wherein said housing further surrounds at least one holding element that limits said amount of frozen carbon dioxide from moving in at least one direction.

14. The system of claim 13, wherein the at least one holding element is formed, at least in part, from a foam material.

15. The system of claim 9, wherein at least one of said first heat exchanger and said second heat exchanger includes a plurality of fins, and said amount of frozen carbon dioxide is disposed against at least one of the plurality of fins.

16. The system of claim 9, wherein the destination is a combustion chamber.

17. The system of claim 9, wherein the bridge line is formed of a flexible material to allow a distance between said first and second heat exchangers to shorten as amount of frozen carbon dioxide sublimates.
