Abstract
Abstract A forced air heat exchange unit comprising at least one horizontally-extending coil of thermally conductive tubing carrying thermally conductive fins thereon and supported between end plates, at least one condensate channel connected across and supported within cut-out portions formed in all of said fins and end plates adjacent the end stream edges thereof to direct condensate from the fins to the area of at least one of said end plates and thereby reduce entrainment of fly-off condensate in the conditioned air.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
In a forced air heat exchange unit having at least one horizontally extending coil of thermally-conductive tubing supported between end plates and carrying thermally-conductive fins thereon, the improvement comprising at least one condensate channel connected across and supported within notches formed in all of said fins and end plates adjacent the downstream edges thereof, whereby condensate formed on said fins is conducted via such channel to the area of at least one of said end plates for collection and disposal, said channel and notches being dimensioned such that one leg and substantially all of the base of said channel nests within said notches with the base of the notches being substantially coextensive in height with said one leg of the channel, the other leg of said channel being of greater dimension than said one leg and extending upwardly outside of said notches in close proximity to the downstream edges of said fins.
Claim 2
Dependent Claim
152 words
In a forced air heat exchange unit having at least one horizontally extending coil of thermally-conductive tubing supported between end plates and carrying thermally-conductive fins thereon, the improvement comprising at least one condensate channel connected across and supported within notches formed in all of said fins and end plates adjacent the downstream edges thereof, whereby condensate formed on said fins is conducted via such channel to the area of at least one of said end plates for collection and disposal, said channel and notches being dimensioned such that one leg and substantially all of the base of said channel nests within said notches with the base of the notches being substantially coextensive in height with said one leg of the channel, the other leg of said channel being of greater dimension than said one leg and extending upwardly outside of said notches in close proximity to the downstream edges of said fins.
Claim 3
Dependent Claim
127 words
In a forced air heat exchange unit comprising at least one horizontally extending coil of thermally-conductive tubing supported between end plates and carrying thermally conductive fins thereon, the improvement comprising at least one condensate channel connected across and supported within cut-out portions formed in all of said fins and end plates adjacent the downstream edges thereof, whereby condensate formed on said fins is conducted via such channel to the area of at least one of said end plates for collection and disposal, said condensate channel comprising individual extruded collars formed on said fins with a cross-sectional configuration of a half-moon, said collars being so dimensioned that when the fins are in position on the coil tubes said collars engage to form a continuous channel across said unit.
Claim 4
Dependent Claim
127 words
In a forced air heat exchange unit comprising at least one horizontally extending coil of thermally-conductive tubing supported between end plates and carrying thermally conductive fins thereon, the improvement comprising at least one condensate channel connected across and supported within cut-out portions formed in all of said fins and end plates adjacent the downstream edges thereof, whereby condensate formed on said fins is conducted via such channel to the area of at least one of said end plates for collection and disposal, said condensate channel comprising individual extruded collars formed on said fins with a cross-sectional configuration of a half-moon, said collars being so dimensioned that when the fins are in position on the coil tubes said collars engage to form a continuous channel across said unit.
