Abstract: Large scale field erected air cooled industrial steam condenser having 10 heat exchanger bundles per cell arranged in five pairs in a V-shape, each heat exchanger bundle having four primary heat exchangers and four secondary heat exchangers in which each secondary heat exchanger is paired with a single primary heat exchanger. Four primary condensers are arranged such that the tubes are horizontal, while the inlet steam manifolds at one end of the tubes are perpendicular to the primary condenser tubes, i.e., parallel to the transverse axis of the bundle. Steam enters the small inlet steam manifolds from below. Cross-sectional dimensions of the tubes are 200 mm wide with a cross-section height of less than 10 mm with fins that are 10 mm in height, arranged at 9 to 12 fins per inch.

Abstract: A method of providing a mould with a conformal cooling passage includes rough machining a mould cavity generally corresponding to a moulded part shape using CAD data. Conformal cooling slots are cut in the mould cavity using the CAD data. The conformal cooling slots are welded shut using the CAD data to provide conformal cooling passages. A class A surface is machined over the conformal cooling passage and corresponds to a finished mould part shape using the CAD data.
