Abstract
Abstract There are disclosed cooling towers and air coolers each having a housing through which air is caused to flow, the housing including a substantially upright conduit having a lower end which is anchored against upward movement, and cell means thereabout which, upon inflation, is adapted to be pneumatically tensed and to lift the conduit into erected position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
121 words
An atmospheric heat exchanger, comprising a housing including a base having air inlet means and air outlet means, and a substantially upright conduit which is anchored at its lower end to the base, said lower end of the conduit having air inlet means in fluid communication with the air outlet means of the base and said upper end of said conduit having air outlet means so that air passing through the base is caused to flow upwardly through the conduit, said conduit having inflated cell means thereabout which pneumatically tenses said conduit and maintains its upper end in upright position, and means extending across the housing for introducing a fluid medium to be cooled into the path of air flowing therethrough.
Claim 2
Dependent Claim
121 words
An atmospheric heat exchanger, comprising a housing including a base having air inlet means and air outlet means, and a substantially upright conduit which is anchored at its lower end to the base, said lower end of the conduit having air inlet means in fluid communication with the air outlet means of the base and said upper end of said conduit having air outlet means so that air passing through the base is caused to flow upwardly through the conduit, said conduit having inflated cell means thereabout which pneumatically tenses said conduit and maintains its upper end in upright position, and means extending across the housing for introducing a fluid medium to be cooled into the path of air flowing therethrough.
Claim 3
Dependent Claim
38 words
An atmospheric heat exchanger of the character defined in claim 1, wherein said conduit comprises a plurality of vertically separated, releasably connected sections, and the cell means includes a portion at the upper end of each conduit section.
Claim 4
Dependent Claim
123 words
A cooling tower, comprising a housing including a base having air inlet means and air outlet means, and a substantially upright conduit defining a stack which is anchored at its lower end to the base, said lower end of the stack having air inlet means in fluid communication with the air outlet means of the base and said upper end of said stack having air outlet means so that air passing through the base is caused to flow upwardly through the stack, said stack having inflated cell means thereabout which pneumatically tenses said stack and maintains its upper end in upright position, and means extending across the housing for introducing a fluid medium to be cooled into the path of air flowing therethrough.
Claim 5
Dependent Claim
123 words
A cooling tower, comprising a housing including a base having air inlet means and air outlet means, and a substantially upright conduit defining a stack which is anchored at its lower end to the base, said lower end of the stack having air inlet means in fluid communication with the air outlet means of the base and said upper end of said stack having air outlet means so that air passing through the base is caused to flow upwardly through the stack, said stack having inflated cell means thereabout which pneumatically tenses said stack and maintains its upper end in upright position, and means extending across the housing for introducing a fluid medium to be cooled into the path of air flowing therethrough.
Claim 6
Dependent Claim
31 words
A cooling tower of the character defined in claim 3, wherein said conduit includes a portion intermediate its upper and lower ends which is hyperbolically shaped upon erection of said stack.
Claim 7
Dependent Claim
23 words
A cooling tower of the character defined in claim 3, including a fan mounted for rotation within the lower end of the stack.
Claim 8
Dependent Claim
158 words
An air cooler, comprising a housing including a lower end providing a base having air inlet means and air outlet means, an upper end having air inlet means and air outlet means, and a substantially upright conduit providing a plenum which is anchored at its lower end to the base, said lower end of the plenum having air inlet means in fluid communication with the air outlet means of the base and said upper end of said plenum having air outlet means in fluid communication with the air inlet means of the upper end of the housing, so that air passing through the base is caused to flow upwardly through the plenum, said plenum having inflated cell means thereabout which pneumatically tenses said plenum and maintains its upper end in upright position, and a tube bundle extending across one end of the housing for introducing a fluid medium to be cooled into the path of air flowing therethrough.
Claim 9
Dependent Claim
158 words
An air cooler, comprising a housing including a lower end providing a base having air inlet means and air outlet means, an upper end having air inlet means and air outlet means, and a substantially upright conduit providing a plenum which is anchored at its lower end to the base, said lower end of the plenum having air inlet means in fluid communication with the air outlet means of the base and said upper end of said plenum having air outlet means in fluid communication with the air inlet means of the upper end of the housing, so that air passing through the base is caused to flow upwardly through the plenum, said plenum having inflated cell means thereabout which pneumatically tenses said plenum and maintains its upper end in upright position, and a tube bundle extending across one end of the housing for introducing a fluid medium to be cooled into the path of air flowing therethrough.
