Self-filling hollow core arterial heat pipe

Claim 2

A heat pipe having a closed casing, a wall capillary and a vaporizable liquid carried thereby and including an axially disposed artery formed by a porous structure disposed around a hollow core, said porous structure having a controlled porosity which permits capillary filling of said porous structure and pressure priming of the hollow core, with said artery and said hollow core providing longitudinal flow of vaporizable liquid, said axially disposed artery being supported in said heat pipe by a plurality of legs.

Claim 3

A heat pipe having a closed casing, a wall capillary and a vaporizable liquid carried thereby and including a supported axially disposed artery formed by a plurality of screen layers that are disposed around a hollow core and are separated by spacing means to provide a spacing of said screen layers which will permit capillary filling of said screen layers and pressure priming of the hollow core, with both providing longitudinal flow of vaporizable liquid, said supported axially disposed artery being supported in said heat pipe by a plurality of legs.

Claim 4

A heat pipe having a closed casing, a wall capillary and a vaporizable liquid carried thereby and including a supported axially disposed artery formed by a plurality of screen layers that are disposed around a hollow core and are separated by spacing means to provide a spacing of said screen layers which will permit capillary filling of said screen layers and pressure priming of the hollow core, with both providing longitudinal flow of vaporizable liquid, said supported axially disposed artery being supported in said heat pipe by a plurality of legs.

Claim 5

the heat pipe of claim 2 wherein the plurality of screen layers are formed by a spirally wound screen.

Claim 6

The heat pipe of claim 2 wherein the plurality of screen layers are concentrically disposed annular rings.

Claim 7

The heat pipe of claim 2 wherein the spacing means comprise a pLurality of elongated rods.

Claim 8

The heat pipe of claim 5 wherein the elongated rods have the same cross-sectional area.

Claim 9

The heat pipe of claim 2 wherein the axially diposed artery is supported in the heat pipe by a plurality of screen mesh legs.

Claim 10

The heat pipe of claim 2 wherein the wall capillary system has a configuration which matches the screening components of the supported axially disposed artery.

Claim 11

The heat pipe of claim 2 wherein the casing of said heat pipe has a substantially linear configuration.

Claim 12

The heat pipe of claim 9 wherein said heat pipe is substantially circular in cross-section.

Claim 13

The heat pipe of claim 9 wherein said heat pipe has a cross-section with at least one flat side.

Claim 14

The heat pipe of claim 2 wherein said screen layers are formed of woven metal wire mesh.

Claim 15

The heat pipe of claim 2 wherein the screen layers are formed of from about 50 to about 350 mesh stainless steel woven wire screening.

Claim 16

The heat pipe of claim 2 wherein the plurality of screen layers are formed of a knitted wire structure.

Claim 17

The heat pipe of claim 2 wherein the wall capillary is a spiral groove which is cut into the wall of the closed casing.

Claim 18

The heat pipe of claim 2 wherein the wall capillary is a series of unconnected, grooves which extend around the internal wall of the heat pipe.

Claim 19

The heat pipe of claim 7 wherein the axially disposed artery is supported by at least two legs that are constructed of screen mesh.
