Abstract
Abstract Improved means for vapor cooling a surface submersed in a liquid cooling agent, said means comprising a fibrous layer held in intimate relation with the surface. The fibrous layer defines a plurality of spacial paths communicating between opposite sides thereof, said paths comprising interspersed vapor conduits and capillaries. In one embodiment the fibrous layer comprises a plurality of stainless steel fibers spun into yarns which are knitted together into a fabric.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
135 words
Apparatus for vapor cooling a heated body, said apparatus comprising of fibrous layer in abutment with a portion of said heated body, said fibrous layer being a fabric formed of strands of yarn, said yarn comprising a plurality of fibers, the interstitial regions between said fibers comprising capillaries for the conduction of liquid, said strands being so arranged in said layer as to provide between adjacent strands line-of-sight vapor conduits extending from the surface of said heated body through said layer, and container means containing a volume of liquid cooling agent in contact with said fibrous layer, said layer being substantially wholly immersed in said liquid cooling agent, whereby said capillaries conduct said liquid cooling agent to the surface of said heated body and said vapor conduits provide substantially unrestricted exits for vaporized cooling agent.
Claim 2
Dependent Claim
135 words
Apparatus for vapor cooling a heated body, said apparatus comprising of fibrous layer in abutment with a portion of said heated body, said fibrous layer being a fabric formed of strands of yarn, said yarn comprising a plurality of fibers, the interstitial regions between said fibers comprising capillaries for the conduction of liquid, said strands being so arranged in said layer as to provide between adjacent strands line-of-sight vapor conduits extending from the surface of said heated body through said layer, and container means containing a volume of liquid cooling agent in contact with said fibrous layer, said layer being substantially wholly immersed in said liquid cooling agent, whereby said capillaries conduct said liquid cooling agent to the surface of said heated body and said vapor conduits provide substantially unrestricted exits for vaporized cooling agent.
Claim 3
Dependent Claim
22 words
The vapor cooling apparatus of claim 1 wherein said fibers are made of materials of lesser thermal conductivity than said heated body.
Claim 4
Dependent Claim
14 words
The vapor cooling apparatus of claim 1 wherein said fibrous layer comprises fiberglass fibers.
Claim 5
Dependent Claim
13 words
The vapor cooling means of claim 1 wherein said fibers are stainless steel.
Claim 6
Dependent Claim
24 words
The vapor cooling apparatus of claim 1 having means holding said fibrous layer in abutment with at least a portion of said heated body.
Claim 7
Dependent Claim
27 words
The vapor cooling apparatus of claim 1 wherein said vapor conduits are parallel to one another and are essentially normal to the surface of said heated body.
Claim 8
Dependent Claim
20 words
The vapor cooling apparatus of claim 1 wherein said heated body is the anode of an external anode electron tube.
Claim 9
Dependent Claim
39 words
The vapor cooling apparatus of claim 7 wherein a portion of said anode is disposed above said level, and another portion of said anode is disposed below said level and wherein said fibrous layer abuts both of said portions.
Claim 10
Dependent Claim
18 words
The improved vapor cooling means of claim 1 wherein said fabric consists of one layer of woven yarn.
Claim 11
Dependent Claim
18 words
The improved vapor cooling means of claim 1 wherein said fabric consists of one layer of knitted yarn.
Claim 12
Dependent Claim
27 words
The improved vapor cooling means of claim 1 wherein said fabric is flexible whereby it may be fitted about said metallic surface when that surface is curved.
Claim 13
Dependent Claim
24 words
The improved vapor cooling means of claim 7 wherein said external anode has a generally cylindrical external surface with massive protuberances extending radially therefrom.
Claim 14
Dependent Claim
30 words
A vapor cooling means in accordance with claim 1 wherein said flexible fabric is held tightly to the side walls of said radially extending massive protuberances by a wire harness.
