Abstract
Abstract A method for making a heat pipe panel comprising the steps of forming parallel furrows in a sheet metal plate, covering the sheet metal plate with another plate, bonding the plate together around the edges and between the furrows, to form parallel cavities between the plates, charging the cavities with working fluid and sealing the cavities to form individual heat pipes in the panel. The furrows may be filled with wicking material, and capillary grooves may be cut in the furrows before bonding the plates together. The cover plate also may have furrows formed therein. A header furrow may be provided for the fluid charging operations.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
100 words
A heat exchanger assembly comprising a housing having a plurality of interior panel support members within a substantially open internal construction and, a plurality of flat sheet heat transfer units mounted on said support members, each of said units including a pair of flat sheets wherein at least one of said sheets includes a plurality of spaced parallel furrows, an integral manifolding channel in fluid communication with said furrows and a common fluid charging port connecting to said manifolding channel, said furrows being sealed off from said manifolding channel after charging to form a plurality of independently operative heat pipes.
Claim 2
Dependent Claim
100 words
A heat exchanger assembly comprising a housing having a plurality of interior panel support members within a substantially open internal construction and, a plurality of flat sheet heat transfer units mounted on said support members, each of said units including a pair of flat sheets wherein at least one of said sheets includes a plurality of spaced parallel furrows, an integral manifolding channel in fluid communication with said furrows and a common fluid charging port connecting to said manifolding channel, said furrows being sealed off from said manifolding channel after charging to form a plurality of independently operative heat pipes.
Claim 3
Dependent Claim
34 words
An assembly as defined in claim 1 wherein said heat transfer units are juxtapositioned in a spaced parallel manner within said assembly as to allow fluid passage between the exterior surfaces of adjacent units.
Claim 4
Dependent Claim
98 words
A high temperature heat exchanger assembly comprising a housing having a plurality of interior panel support members within a substantially open internal construction and, a plurality of high temperature continuously operating heat transfer units mounted on said support members, each of said units including a pair of corrugated hastelloy sheets coupled together to form fluid channels therebetween, said sheets further including integral internal manifolding means for charging said channels with a working fluid suitable for high temperature operation, said channels being sealed off from said manifolding means after charging to form a plurality of independently operative heat pipes.
Claim 5
Dependent Claim
98 words
A high temperature heat exchanger assembly comprising a housing having a plurality of interior panel support members within a substantially open internal construction and, a plurality of high temperature continuously operating heat transfer units mounted on said support members, each of said units including a pair of corrugated hastelloy sheets coupled together to form fluid channels therebetween, said sheets further including integral internal manifolding means for charging said channels with a working fluid suitable for high temperature operation, said channels being sealed off from said manifolding means after charging to form a plurality of independently operative heat pipes.
Claim 6
Dependent Claim
14 words
The assembly as defined in claim 3 wherein said channels are charged with sodium.
