Abstract
Abstract A fin-tube heat exchange coil having heavy gauge plates connected to selected core tubes of a coil so that the plates act as rigid extensions within the centrodial area of a coil. The plates, different than tube sheets, may be used either to orient and mount equipment, for example a motor, in a fixed relation to the coil or to mount and support the coil from its center or ends in a fixed relation to its associated equipment. The fixed mounting relation to the coil can be at all four mounting quadrants, i.e.: top, bottom, front and rear or angled therein.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
In combination: a rigid fin-tube heat exchange coil; at least one non-rigid element associated with said coil; and at least one heavy gauge plate extending from the coil in supporting relation to the associated element whereby said element takes on the rigidity of the coil; said plate being positioned between adjacent fins and having openings therein to receive selected tubes mechanically to join the plate to the coil, the fins being plate-type fins extending transversely across the tubes; said fins having tube-encircling collars extending through said openings in the plate; and the fin collars having tight fits within the plate openings mechanically to lock the tube, fin and plate together.
Claim 2
Dependent Claim
110 words
In combination: a rigid fin-tube heat exchange coil; at least one non-rigid element associated with said coil; and at least one heavy gauge plate extending from the coil in supporting relation to the associated element whereby said element takes on the rigidity of the coil; said plate being positioned between adjacent fins and having openings therein to receive selected tubes mechanically to join the plate to the coil, the fins being plate-type fins extending transversely across the tubes; said fins having tube-encircling collars extending through said openings in the plate; and the fin collars having tight fits within the plate openings mechanically to lock the tube, fin and plate together.
Claim 3
Dependent Claim
17 words
The combination of claim 1 wherein the plate thickness is approximately the same as the fin spacing.
Claim 4
Dependent Claim
16 words
The combination of claim 2 wherein the plate thickness is appreciably greater than the fin thickness.
Claim 5
Dependent Claim
14 words
The combination of claim 1 wherein the associated element is a motor fan assembly.
Claim 6
Dependent Claim
21 words
The combination of claim 1 wherein the tubes are expanded into bonded connection with the tube encircling fin collars and plates.
