Abstract
Abstract An inner annular radiator has fluid passageway means and radial air passageway means. An outer annular radiator is radially spaced from the inner annular radiator and has fluid passageway means and radial air passageway means. Air propelling means includes a fan located at one side of the inner and outer annular radiators for moving air through the air passageway means thereof in opposite directions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
A radiator assembly, comprising; an inner annular radiator having a plurality of axially spaced generally arcuate fluid carrying core elements, arcuate radial flow air passageway means between said core elements, an outer annular radiator surrounding said inner radiator and having a plurality of axially spaced arcuate fluid carrying core elements, arcuate radial flow air passageway means between said outer radiator core elements, an axially extending substantially unobstructed annular space between the inner and outer radiators, fan means positioned to convey air axially through said annular space, and means for directing the conveyed air simultaneously radially in one direction through the air passageway means in said inner annular radiator and in the opposite direction through the air passageways means in the outer annular radiator.
Claim 2
Dependent Claim
123 words
A radiator assembly, comprising; an inner annular radiator having a plurality of axially spaced generally arcuate fluid carrying core elements, arcuate radial flow air passageway means between said core elements, an outer annular radiator surrounding said inner radiator and having a plurality of axially spaced arcuate fluid carrying core elements, arcuate radial flow air passageway means between said outer radiator core elements, an axially extending substantially unobstructed annular space between the inner and outer radiators, fan means positioned to convey air axially through said annular space, and means for directing the conveyed air simultaneously radially in one direction through the air passageway means in said inner annular radiator and in the opposite direction through the air passageways means in the outer annular radiator.
Claim 3
Dependent Claim
163 words
The radiator assembly of claim 1 wherein said inner annular radiator comprises diametrically opposed first and second tank portions, and a pair of substantially semi-circular core portions including said core elements connected at their ends to said first and second tank portions and with said plurality of core elements being parallel and defining a plurality of fluid passageways axially spaced to define intermediate air passageways, said outer annular radiator including diametrically opposed third and fourth tank portions, a pair of substantially semi-circular core portions including said core elements connected at their ends to said third and fourth tank portions and with said plurality of core elements being parallel and defining a plurality of fluid passageways axially spaced to define intermediate air passageways, fluid inlet means connected to said third tank portion, fluid outlet means connected to said fourth tank portion, first fluid conduit means between said first and third tank portions, and second fluid conduit means between said second and fourth tank portions.
Claim 4
Dependent Claim
61 words
The radiator assembly of claim 2 wherein said means for directing conveyed air includes a circular closure extending radially across said inner annular radiator at said one side thereof, an annular closure extending radially between said inner and outer annular radiators at the other side thereof, and an annular shroud concentric of said fan and secured to said outer annular radiator.
Claim 5
Dependent Claim
61 words
The radiator assembly of claim 1 wherein said means for directing conveyed air includes a circular closure extending radially across said inner annular radiator at said one side thereof, an annular closure extending radially between said inner and outer annular radiators at the other side thereof, and an annular shroud concentric of said fan and secured to said outer annular radiator.
