Abstract
The present invention is a cooling vest which has a type of phase change heat sink that particularly lends itself to layering of the heat sinks on the body. The heat sinks are quilted and have a means for the transportation of moisture through them and the means of transportation of air through channels in the quilted heat sinks. Thus they can remove moisture from the surface of the body and remain flexible.
Claims7
A method of cooling the body of a wearer of a cooling garment and transporting moisture away from said body, said method comprised of the following steps:
- a) providing a supporting means,
- b) supporting a heat sink next to said body,
- c) evaporating moisture from said body,
- d) transferring said moisture to said heat sink,
- e) condensing said moisture into liquid phase water on said heat sink,
- f) absorbing liquid phase water into said heat sink,
- thus cooling said body by evaporating moisture away from said body and transporting moisture away from said body.
A method of enabling flexibility in a cooling garment, said method comprised of the following steps:
- a) providing a supporting means,
- b) supporting a plurality of cold surface layers next to body,
- c) said plurality of cold surfaces having means to slide on adjacent surfaces with movement of said body, thus enabling flexibility of cooling garment.
A garment to cool the body comprising multiple heat sink layers.
A method of cooling a garment, by sublimation of liquid to a gas between an interior surface and an exterior surface and transporting said gas to exterior of said garment said method comprised of the following steps:
- a) providing a supporting structure,
- b) supporting said cooling garment layer with interior surface next to body and exterior surface facing away from body,
- c) providing said exterior surface layer with molecular sieve function,
- d) sublimating liquid to a gas between said interior and said exterior surface,
- e) transporting said gas from between said interior and said exterior surfaces to exterior of vest, thus cooling said garment by sublimation of liquid to a gas between an interior surface and an exterior surface and transporting said gas to exterior of said garment.
