Abstract
Abstract A heat exchange assembly including a heat transfer coil having a relatively cold heat exchange medium supplied thereto. The coil includes tube sheets provided at each end thereof, each of the tube sheets having at least one tab extending outwardly from the surface. A relatively warm medium is passed in heat transfer relation with the cold heat exchange medium, the warm medium being cooled thereby. A condensate collection pan is disposed below and extends substantially coextensive with the lower surface of the heat transfer coil to permit condensate formed on the surface of the coil to drain into the collection pan. Slots are formed at either end of the collection pan for receiving the tabs extending from the tube sheet to secure the collection pan to the heat transfer coil.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
A heat exchange assembly comprising: a. heat transfer means having a relatively cold heat exchange fluid passing therethrough, said heat transfer means including at least one tab means extending from each surface defining the ends of said heat transfer means; b. means to pass a relatively warm medium in heat transfer relation with the relatively cold heat exchange medium passing through said heat transfer means, said warm medium being cooled thereby resulting in the formation of condensate on said heat transfer means; and c. means to collect said condensate, said collection means being disposed below and extending substantially coextensive with the lower surface of said heat transfer means to permit said condensate to drain into said collection means, sAid collection means including means defining a slot at each end thereof, each of said slot defining means receiving one of said tab means extending from said heat transfer means to secure said collection means to said heat transfer means.
Claim 2
Dependent Claim
158 words
A heat exchange assembly comprising: a. heat transfer means having a relatively cold heat exchange fluid passing therethrough, said heat transfer means including at least one tab means extending from each surface defining the ends of said heat transfer means; b. means to pass a relatively warm medium in heat transfer relation with the relatively cold heat exchange medium passing through said heat transfer means, said warm medium being cooled thereby resulting in the formation of condensate on said heat transfer means; and c. means to collect said condensate, said collection means being disposed below and extending substantially coextensive with the lower surface of said heat transfer means to permit said condensate to drain into said collection means, sAid collection means including means defining a slot at each end thereof, each of said slot defining means receiving one of said tab means extending from said heat transfer means to secure said collection means to said heat transfer means.
Claim 3
Dependent Claim
29 words
An assembly in accordance with claim 1 wherein at least one of said slot defining means includes a movable finger for engaging said tab means received in said slot.
Claim 4
Dependent Claim
28 words
An assembly in accordance with claim 2 wherein said movable finger includes a cam, the bottom surface of said cam engaging the top surface of said tab means.
Claim 5
Dependent Claim
185 words
A heat exchange assembly comprising: a. heat transfer means including a plurality of tubes having a relatively cold heat exchange fluid passing therethrough, a plurality of fins extending outwardly from the surface of said tubes to increase the heat transfer surface, and a tube sheet provided at each end of said heat transfer means, each of said tube sheets having at least one tab means extending outwardly from the surface thereof; b. means to pass a relatively warm medium in heat transfer relation with the relatively cold heat exchange medium passing through said heat transfer means, said warm medium being cooled thereby resulting in the formation of condensate on the surface of said fins; and c. means to collect said condensate, said collection means being disposed below and extending substantially coextensive with the bottom surface of said heat transfer means to permit said condensate to drain into said collection means, said collection means including means defining a slot at each end thereof, said slot defining means receiving said tab means extending from said tube sheet to secure said collection means to said heat transfer means.
Claim 6
Dependent Claim
185 words
A heat exchange assembly comprising: a. heat transfer means including a plurality of tubes having a relatively cold heat exchange fluid passing therethrough, a plurality of fins extending outwardly from the surface of said tubes to increase the heat transfer surface, and a tube sheet provided at each end of said heat transfer means, each of said tube sheets having at least one tab means extending outwardly from the surface thereof; b. means to pass a relatively warm medium in heat transfer relation with the relatively cold heat exchange medium passing through said heat transfer means, said warm medium being cooled thereby resulting in the formation of condensate on the surface of said fins; and c. means to collect said condensate, said collection means being disposed below and extending substantially coextensive with the bottom surface of said heat transfer means to permit said condensate to drain into said collection means, said collection means including means defining a slot at each end thereof, said slot defining means receiving said tab means extending from said tube sheet to secure said collection means to said heat transfer means.
Claim 7
Dependent Claim
29 words
An assembly in accordance with claim 1 wherein at least one of said slot defining means includes a movable finger for engaging said tab means received in said slot.
Claim 8
Dependent Claim
28 words
An asembly in accordance with claim 2 wherein said movable finger includes a cam, the bottom surface of said cam engaging the top surface of said tab means.
