Abstract
Abstract A heat transfer device comprising in one embodiment concentric tubes with spaced surfaces to define a fluid flow space through which a heat transfer fluid is directed and with this space being spanned by a series of fins extending between the tubes with at least one of the tubes being provided with spaced contact members extending toward the other tube and engaging the fins compressively to provide snug heat transfer contact between the boundary members or tubes and the fins so as to compensate for variations in the dimensions in one or both of the tubes and fins.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
77 words
A heat transfer device comprising: first and second boundary members having surfaces spaced apart to define a fluid flow space; a heat transfer member substantially spanning said space to be contacted by said fluid, said member comprising a deformable heat transfer material; and spaced contact members on one of said boundary members engaging, at correspondingly spaced locations, said heat transfer member compressively to provide snug heat transfer contact between said boundary members and said heat transfer member.
Claim 2
Dependent Claim
77 words
A heat transfer device comprising: first and second boundary members having surfaces spaced apart to define a fluid flow space; a heat transfer member substantially spanning said space to be contacted by said fluid, said member comprising a deformable heat transfer material; and spaced contact members on one of said boundary members engaging, at correspondingly spaced locations, said heat transfer member compressively to provide snug heat transfer contact between said boundary members and said heat transfer member.
Claim 3
Dependent Claim
29 words
The device of claim 1 wherein said first and second boundary members comprise substantially concentric tubes and said heat transfer member has portions extending substantially radially of said tubes.
Claim 4
Dependent Claim
31 words
The device of claim 2 wherein said tubes are essentially concentric and said heat transfer member comprises a continuous serpentine fin of thin metal with opposite crests adjacent said boundary surfaces.
Claim 5
Dependent Claim
28 words
The device of claim 1 wherein said contact members comprise rings at said spaced location on said one boundary member and engaging and deforming the heat transfer member.
Claim 6
Dependent Claim
15 words
The device of claim 4 wherein said rings are integral with said one boundary member.
Claim 7
Dependent Claim
18 words
The device of claim 4 wherein said rings are separate from but mounted on said one boundary member.
Claim 8
Dependent Claim
81 words
A heat transfer device comprising: first and second concentric tubes defining boundary members having surfaces spaced apart to define a fluid flow space; a heat transfer fin substantially spanning said space to be contacted by said fluid, said fin comprising a deformable heat transfer metal; and spaced rings on one of said boundary members each having a crest engaging said fin at an edge thereof compressively to provide snug heat transfer contact between said tubular means and said heat transfer member.
Claim 9
Dependent Claim
81 words
A heat transfer device comprising: first and second concentric tubes defining boundary members having surfaces spaced apart to define a fluid flow space; a heat transfer fin substantially spanning said space to be contacted by said fluid, said fin comprising a deformable heat transfer metal; and spaced rings on one of said boundary members each having a crest engaging said fin at an edge thereof compressively to provide snug heat transfer contact between said tubular means and said heat transfer member.
Claim 10
Dependent Claim
31 words
The device of claim 7 wherein said tubes are essentially concentric and said heat transfer member comprises a continuous serpentine fin of thin metal with opposite crests adjacent said boundary surfaces.
Claim 11
Dependent Claim
25 words
The device of claim 7 wherein said contact members comprise spaced rings on said one boundary member and engaging and deforming the heat transfer member.
Claim 12
Dependent Claim
15 words
The device of claim 9 wherein said rings are integral with said one boundary member.
Claim 13
Dependent Claim
18 words
The device of claim 9 wherein said rings are separate from but mounted on said one boundary member.
