Abstract

The present invention relates to a cooling garment, comprising: a moisture-wicking under layer; and an impermeable outer layer, wherein the impermeable outer layer is attached to the moisture-wicking under layer forming at least one channel within the garment having a wetted perimeter of at most 5 inches; and an above ambient pressure gas supply operably attached to the channel. The present invention also relates to the cooling shirt or vest garment, comprising: a moisture-wicking under layer and an impermeable outer layer, wherein the outer layer is attached to the under layer forming a plurality of channels.

First claim

What is claimed is:

1. A cooling shirt or vest garment, the cooling garment formed of:
(a) a moisture-wicking under layer;
(b) an impermeable outer layer, wherein an impermeable outer layer is attached to the outer surface of the moisture-wicking under layer;
(c) at least one channel within the moisture-wicking under layer having an internal wetted perimeter of at most 5 inches and said impermeable outer layer; and
(d) an above ambient pressure gas supply operably attached to the channel to thereby cool the wearer of the cooling garment.

2. The garment of claim 1 , further comprising at least two channels, wherein the two channels are substantially adjacent to each other.

3. The garment of claim 1 , further comprising at least two channels, and at least one gap, wherein the two channels are separated by the gap.

4. The garment of claim 1 , wherein hydraulic diameter of the channel is at most 1 inch.

5. The garment of claim 4 , wherein hydraulic diameter of the channel is about 0.5 inches.

6. The garment of claim 1 , wherein the above ambient pressure gas supply is either a fan, a positive displacement pump, or a compressed gas tank.

7. The garment of claim 1 , wherein the garment is a shirt or a vest with at least 20 channels.

8. A cooling shirt or vest garment, the cooling garment formed of:
(a) a moisture-wicking under layer;
(b) an impermeable outer layer, wherein the impermeable outer layer is attached to the moisture-wicking under layer forming a plurality of channels, wherein each channel is formed in part from the moisture-wicking under layer and in part from the impermeable outer layer, and each of the channels has an internal perimeter comprising:
(i) a wicking layer segment having a wicking layer internal perimeter segment length of at most 2 inches;
(ii) an outer layer segment having an outer layer internal perimeter segment length of at most 3 inches; and

(c) an above ambient pressure gas supply operably attached to the channels with a manifold to thereby cool the wearer of the cooling garment.

9. The cooling garment of claim 8 , wherein the wicking layer internal perimeter segment length is at most 0.2 inches.

10. The garment of claim 1 , wherein the channels are semicircular tubes with a diameter from 0.04 to 1.0 inches.

11. The garment of claim 10 , wherein the channels have a diameter of about 0.5 inches.

12. The garment of claim 10 , wherein the channels have a diameter from 0.04 to 0.2 inches.

13. The garment of claim 10 , wherein the garment is a shirt with 300 to 400 channels.

14. The garment of claim 8 , wherein the garment is a shirt or a vest with at least 20 channels.

15. The garment of claim 8 , wherein the channels are triangular pleats and the wicking layer internal perimeter segment length is from 0.04 to 1.0 inches.

16. The garment of claim 15 , wherein the wicking layer internal perimeter segment length is from 0.04 to 0.2 inches.

17. The garment of claim 8 , wherein the channels further comprise an airflow direction that is either substantially up, substantially down, or substantially horizontal, or combinations thereof.

18. The garment of claim 8 , wherein the garment further comprises at least one redistribution manifold.

19. The cooling garment of claim 8 , wherein at least one of the channels has a cross section further comprising:
(iii) at least one wall segment, having a wall internal perimeter segment length of at most 0.5 inches; and
wherein the channel has a total wetted perimeter of no more than 5 inches.

20. The garment of claim 19 , wherein the channels are substantially rectangular channels with a wicking layer internal perimeter segment length from 0.1 to 1.0 inches, an outer layer internal perimeter segment length from 0.1 to 1.0 and a wall internal perimeter segment length from 0.1 to 0.5 inches.
