Claims
- 1. An apparatus for continuously vaporizing a cryogenic liquid by employing heat absorbed from the ambient air comprising at least three substantially vertical positioned passes which are piped together each pass being comprised of a center tube having an outside diameter of from 0.5 to 1.5 inches and provided with 3 to 8 fins substantially equally spaced around said tube, each fin having a radial length of from 1.5 to 7 times the outside diameter of said tube and extending longitudinally along substantially the entire length of said tube, each pass having a length of from 5 to 20 feet and a ground clearance of from 1 to 4 feet, and wherein the ratio of the distance between adjacent fin tips to radial fin length is from 1 to 5 to define a substantially open space between adjacent fin tips.
- 2. An atmospheric vaporizer as claimed in claim 1 wherein said ratio is from 2 to 4.
- 3. An atmospheric vaporizer as claimed in claim 1 wherein said ratio is about 3.
- 4. An atmospheric vaporizer as claimed in claim 1 wherein said passes are arranged in a square array.
- 5. An atmospheric vaporizer as claimed in claim 1 wherein said passes are arranged in a triangular array.
- 6. An atmospheric vaporizer as claimed in claim 1 wherein said passes are provided with 3 fins.
- 7. An atmospheric vaporizer as claimed in claim 1 wherein said passes are provided with 4 fins.
- 8. An atmospheric vaporizer as claimed in claim 1 wherein said passes are provided with 8 fins.
- 9. An atmospheric vaporizer as claimed in claim 1 wherein said fin radial length is about 3.5 times the outside diameter of the center tube.
- 10. An atmospheric vaporizer as claimed in claim 1 wherein said passes have a ground clearance of from 1.5 to 3 feet.
- 11. An atmospheric vaporizer as claimed in claim 1 wherein said center tube outside diameter is about 1 inch.
- 12. An atmospheric vaporizer as claimed in claim 1 wherein said pass length is from 8 to 16 feet.
- 13. An atmospheric vaporizer as claimed in claim 1 wherein said pass length is about 12 feet.
