Abstract
Abstract A heat exchanger arrangement wherein a plurality of cylindrical modular heat exchanger units are stacked upright in side-by-side relation within an enclosure and can be transferred into and out of the enclosure, one at a time, through a passage in the floor thereof. To transfer any given heat exchanger unit out of the enclosure, the unit is detached from its base, hoisted by an overhead travelling crane into a position overlying the floor passage and then lowered vertically into a basculating bridge underneath the floor. The bridge is then tilted into a horizontal attitude to discharge the unit. Transfer of a unit into the enclosure is accomplished by following the foregoing procedure in reverse order.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
138 words
A heat exchanger arrangement which comprises means defining a hollow enclosure having a generally horizontal floor and a passage extending downwardly through said floor; a plurality of cylindrical modular heat exchanger units disposed upright within said enclosure in side-by-side relation to one another, each of said units having a base supported by said floor; and overhead crane positioned for movement in overlying relation to said units to hoist any one unit at a time and transport same from its original position within the enclosure to a position overlying said floor passage, and to lower said unit through said passage in a generally vertical attitude; and a basculating bridge means disposed in underlying relation to said floor passage, said bridge being pivotably moveable between a vertical attitude and a horizontal attitude to respectively receive said unit and discharge same.
Claim 2
Dependent Claim
138 words
A heat exchanger arrangement which comprises means defining a hollow enclosure having a generally horizontal floor and a passage extending downwardly through said floor; a plurality of cylindrical modular heat exchanger units disposed upright within said enclosure in side-by-side relation to one another, each of said units having a base supported by said floor; and overhead crane positioned for movement in overlying relation to said units to hoist any one unit at a time and transport same from its original position within the enclosure to a position overlying said floor passage, and to lower said unit through said passage in a generally vertical attitude; and a basculating bridge means disposed in underlying relation to said floor passage, said bridge being pivotably moveable between a vertical attitude and a horizontal attitude to respectively receive said unit and discharge same.
Claim 3
Dependent Claim
28 words
A heat exchanger arrangement according to claim 1 wherein one of said heat exchanger units is normally disposed within said enclosure in overlying relation to said floor passage.
Claim 4
Dependent Claim
55 words
A heat exchanger arrangement according to claim 1 wherein said heat exchanger units are positioned in an equilateral triangular center spacing arrangement and one of said units is smaller in diameter than the others to establish a predetermined clearance space within said enclosure to facilitate transfer of said units into and out of the enclosure.
Claim 5
Dependent Claim
64 words
A heat exchanger arrangement according to claim 1 including a sealing bulb member disposed within the base of each of said heat exchanger units to establish a fluid pressuretight seal between said base and the upper poRtion of the unit, and header means extending through said base and sealing bulb member for communication with a tube bundle in the upper portion of the unit.
Claim 6
Dependent Claim
63 words
A heat exchanger arrangement according to claim 1 wherein the base of each heat exchanger unit has a dodecagonal flange positioned for contact with said floor and for edgewise adjoining engagement with the flanges of adjacent unit bases to define triangular openings between groups of adjoining flanges, and including a plurality of triangular plates matching said openings and disposed therein to seal same.
Claim 7
Dependent Claim
29 words
A heat exchanger arrangement according to claim 2 wherein said enclosure is cylindrical and said floor passage is centrally located with respect to the lateral boundaries of the enclosure.
Claim 8
Dependent Claim
44 words
A heat exchanger arrangement according to claim 6 wherein the heat exchanger unit overlying said floor passage has a sheath extending through said passage in circumferentially contiguous relation therewith, and a seal member connected to said sheath to define a fluid pressuretight closure therefor.
Claim 9
Dependent Claim
16 words
A heat exchanger arrangement according to claim 7 including biological shielding means disposed within said sheath.
Claim 10
Dependent Claim
30 words
A heat exchanger arrangement according to claim 4 wherein said heat exchanger units each have a tubular sheath extending through said floor and said header means extends through said sheath.
