A fluid distributor for mounting in the upper end of a vertical condenser tube, comprising a ferrule having a downwardly opening cavity therein, the cavity including a lower frusto-conical portion and an upper spherical portion which is tangential to said lower portion. The ferrule has an enlarged head portion containing at least one inlet orifice, the orifice extending upwardly at an angle from a horizontal plane passing through the upper end of the ferrule chamber, and the inner end thereof opening tangentially on the wall defining the spherical chamber portion. Fluid entering the ferrule chamber through the inlet orifice is directed thereby both laterally and downwardly, to establish an inverted vortex from which is formed a uniform hollow cylindrical film of fluid.

A fluid distributor for use in the upper end of a vertical condenser tube in a falling film type heat exchanger or the like, for forming a hollow cylindrical film of fluid on the interior surface of said condenser tube, said fluid distributor comprising: a ferrule, said ferrule including a lower portion having a cylindrical exterior and sized to be received within the upper end of a vertical condenser tube, and an enlarged head portion on the upper end of said lower portion; the interior of said ferrule having a completely open chamber extending upwardly from the lower end thereof, said chamber including a frusto-conical lower portion defined by a frusto-conical wall and having a diameter at the lower end thereof about the same as the exterior diameter of said ferrule lower portion, and a spherically shaped upper portion defined by a spherical wall and arranged concentrically of the vertical axis of said chamber, said spherical wall being tangent to the upper end of said frusto-conical wall; and said enlarged ferrule head portion having at least one inlet orifice therein, the axis of said inlet orifice being inclined upwardly from a horizontal plane passing through the upper end of said chamber, and the inner end of said inlet orifice opening tangentially onto said spherical wall defining said spherically shaped upper chamber portion, whereby fluid entering said ferrule chamber through said inlet orifice is directed both laterally and downwardly against said chamber walls and swirls within the upper end of said chamber to establish an inverted vortex, and to form a rotating, uniform hollow cylindrical film of fluid which flows evenly and without interruption downwardly on the interior surface of said condenser tube.
