Abstract
Abstract An omni-directional heat pipe for cooling a local heat area, such as in electronic circuitry, including a sealed cavity for containment of multiple capillary-like coolant paths which may be inter-connectable or otherwise disposed in order to facilitate wide angle heat transfer dispersion. Said sealed cavity may be compressed as between said local heat areas and local cool areas. Said multiple capillary-like coolant paths comprising flexible tubing structured to permit ready flow of heat through evaporation at the hottest region, flow of the vapor to the cooler regions which is achieved as a result of inherently lower thermodynamic pressure, and the return of the condensate through a myriad of channels or capillaries acting as wick or surface tension induced flow, ready use as a thermal couple between respective high & low temperature regions.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
96 words
An omni-directional heat pipe comprising: an outer receptacle including an outer skin, an inner skin, and a cavity; an inner receptacle surrounded by said outer receptacle and including an innermost cavity; and, a plurality of conduits located between said inner skin and said inner receptacle, each of said plurality of conduits including a first end and a second end, said first end in abutting relation with said inner skin, said second end perforating said inner receptacle and opening into said innermost cavity; and, means for transferring heat including a working fluid substantially contained within said conduits.
Claim 2
Dependent Claim
96 words
An omni-directional heat pipe comprising: an outer receptacle including an outer skin, an inner skin, and a cavity; an inner receptacle surrounded by said outer receptacle and including an innermost cavity; and, a plurality of conduits located between said inner skin and said inner receptacle, each of said plurality of conduits including a first end and a second end, said first end in abutting relation with said inner skin, said second end perforating said inner receptacle and opening into said innermost cavity; and, means for transferring heat including a working fluid substantially contained within said conduits.
Claim 3
Dependent Claim
15 words
An omni-directional heat pipe as in claim 1 said plurality of conduits including multiple perforations.
Claim 4
Dependent Claim
24 words
An omni-directional heat pipe as in claim 2, said multiple perforations being located at said first end of each of said plurality of conduits.
Claim 5
Dependent Claim
28 words
An omni-directional heat pipe as in claim 2, said multiple perforations being sized and proportioned to permit the escape of vapor and to permit the infusion of condensate.
Claim 6
Dependent Claim
30 words

Dependent Claim
47 words
An omni-directional heat pipe as in claim 2 wherein said multiple perforations facilitating the escape of vapor of said working fluid from said plurality of conduits and into said cavity during evaporation, and, facilitating the flow of condensate from said cavity into said working fluid during condensation.
Claim 8
Dependent Claim
85 words
An omni-directional heat pipe assembly comprising: a receptacle including an outer skin, an inner skin, and a cavity; a plurality of conduits located within said cavity, each of said conduits including a first end and a second end, said first end and said second end in substantially abutting relation with said inner skin; means for maintaining said first end and said second end in substantially abutting relation with said inner skin; and, means for transferring heat including a working fluid substantially contained within said conduits.
Claim 9
Dependent Claim
85 words
An omni-directional heat pipe assembly comprising: a receptacle including an outer skin, an inner skin, and a cavity; a plurality of conduits located within said cavity, each of said conduits including a first end and a second end, said first end and said second end in substantially abutting relation with said inner skin; means for maintaining said first end and said second end in substantially abutting relation with said inner skin; and, means for transferring heat including a working fluid substantially contained within said conduits.
