Abstract
Abstract A modular air cooled condenser apparatus having an elongated tubular manifold serving as a backbone principal support for other elements of the apparatus, a plurality of condenser cores supported on the manifold at an angle to the horizontal to provide gravity drainage back into the manifold, a fan shroud and fan supported between the cores, a motor drive structure mounted on the manifold and connected to the fan and a rigid frame interconnecting the manifold, cores and shroud in a selfsupporting module unit joinable at the manifold to other such units to provide any desired condensing capacity. Each modular unit is preferably of a size that can be constructed in the factory and shipped as on a flatcar to its destination so as to require a minimum of erection in the field.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
A modular air cooled condenser apparatus for condensing condensible gases to liquid condensate, comprising: an elongated hollow manifold backbone for containing both said gas and said liquid; means for supplying said gas to the manifold; means for removing said liquid from the manifold; a plurality of air pervious hollow condenser cores supported on said manifold at an angle to the horizontal with their lower ends attached to said manifold, said manifold and cores having their interiors connected for passage of said gas from the manifold into the cores and the gravity flow of said liquid from the cores to the manifold; means for spacing the upper ends of said cores apart; a fan shroud between said spaced cores above the manifold; a fan within said shroud; a motor drive structure mounted on said manifold and connected to said fan for driving the same; and a rigid frame interconnecting said manifold, cores and shroud in a self-supporting module unit of which the tubular manifold is the supporting backbone, said unit being joinable at the manifold to other said module units.
Claim 2
Dependent Claim
179 words
