Abstract

An air separation module includes a housing, an air separation element, and an insulating element. The housing has an inlet and two outlets. The air separation element is enclosed within the housing and extends along a length of the housing. The insulating element is positioned inward of an outer perimeter of the housing and substantially surrounds an outer perimeter of the air separation element along a length of the air separation element.

First claim

The invention claimed is:

1. An air separation module comprising:
a housing comprising:
an inlet; and
a first and second outlet;

an air separation element enclosed within the housing and extending along a length of the housing, wherein the air separation element comprises a plurality of semi-permeable fibers configured to release oxygen-enriched air along a length of the air separation element; and
an insulating element inward of an outer perimeter of the housing and substantially surrounding an outer perimeter of the air separation element along the length of the air separation element.

2. The air separation module of claim 1 , wherein the housing further comprises:
a first wall and a second wall each extending along the length of the housing, wherein the first wall is positioned outward of the second wall.

3. The air separation module of claim 2 , wherein the housing further comprises a vacuum space between the first and second wall, and wherein the vacuum space forms the insulating element.

4. The air separation module of claim 2 , wherein the insulating element comprises an insulating medium positioned between the first and second wall.

5. The air separation module of claim 1 , wherein the first outlet is located at a position along the length of the housing and extends through the housing.

6. The air separation module of claim 1 , further comprising:
a fluid collection chamber positioned between the air separation element and the housing, and wherein the first outlet is in fluid communication with the fluid collection chamber.

7. The air separation module of claim 1 , further comprising a fluid collection chamber positioned at an end of the air separation element opposite the inlet, and wherein the second outlet is in fluid communication with the fluid collection chamber.

8. The air separation module of claim 1 , wherein the insulating element is wrapped around the air separation element, such that the insulating element is in contact with at least a portion of each of an inner wall of the housing and the outer perimeter of the air separation element.

9. An air separation module comprising:
an air separation element, wherein the air separation element comprises a plurality of semi-permeable fibers configured to release oxygen-enriched air along a length of the air separation element;
an insulating element substantially surrounding an outer perimeter of the air separation element along the length of the air separation element; and
a housing having an inlet, a first outlet, and a second outlet, wherein the housing encloses the combination of the insulating element and the air separation element.

10. The air separation module of claim 9 , wherein the insulating element is positioned in contact with at least a portion of each of an inner wall of the housing and the outer perimeter of the air separation element.

11. The air separation module of claim 9 , further comprising:
a fluid collection chamber positioned between the insulating element and the air separation element.

12. The air separation module of claim 11 , wherein a hole through the insulating element fluidly connects the first outlet to the fluid collection chamber.

13. The air separation module of claim 9 , wherein the first outlet is located at a position along a length of the housing and extends through the housing.

14. The air separation module of claim 9 , wherein the second outlet is located at an end of the air separation element opposite the inlet.

15. The air separation module of claim 9 , further comprising a seal between the air separation element and the housing configured to prevent an air flow from bypassing the air separation element.

16. The air separation module of claim 9 , wherein the housing further comprises:
a first end having the inlet; and
a second end having the second outlet, wherein at least one of the first and second ends are detachable and wherein the air separation element is separable from the air separation module and can be removed from the housing through at least one of the first and second ends and replaced with another air separation element.

17. A method of making an air separation module to improve efficiency of separation, the method comprising the steps of:
fabricating a housing for an air separation module, wherein the housing comprises an inlet, a first outlet, and a second outlet;
positioning an air separation element within the housing, wherein the air separation element extends substantially along a length of the housing, and wherein the air separation element comprises a plurality of semi-permeable fibers configured to release oxygen-enriched air along the length of the air separation element; and
providing an insulating element inward of an outer perimeter of the housing and substantially surrounding an outer perimeter of the air separation element along the length of air separation element.

18. The method of claim 17 , wherein fabricating the housing comprises forming a first and second wall each extending along the length of the housing and wherein the first wall is positioned outward of the second wall.

19. The method of claim 18 , wherein providing an insulating element comprises placing an insulating medium between the first and second wall.

20. The method of claim 18 , wherein the insulating element comprises a vacuum space formed between the first and second wall.
