Cooling arrangement and method for cooling of a heat source. The cooling arrangement comprises a closed loop, a semi-open loop and at least one fan. The closed loop comprises a primary side of a liquid-to-liquid heat exchanger receiving a first cooling fluid heated by the heat source, a first air-to-liquid heat exchanger downstream said primary side, and a first pump returning the first cooling fluid to the heat source. The semi-open loop comprises a tank storing a second cooling fluid, a second pump drawing the second cooling fluid from the tank, a secondary side of the liquid-to-liquid heat exchanger receiving the second cooling fluid from the second pump, an evaporating pad downstream said secondary side, and an inlet fluidly connected to a source of the second cooling fluid. The at least one fan causes an air flow through the evaporating pad and through the first air-to-liquid heat exchanger.

Heat exchanger fins and heat exchangers are disclosed. The heat exchanger fins disclosed herein comprise louvers and winglet-type vortex generators arranged to improve heat transfer efficiency.

A large scale field erected air cooled industrial steam condenser having heat exchanger panels independently loaded into and supported in a heat exchange frame section. A bottom bonnet runs along the bottom length of each heat exchanger panel for delivering steam to the bottom end of condenser tubes in the heat exchange panel and for receiving condensate formed in those same tubes. The tops of the tubes are connected to a top bonnet. Uncondensed steam and non-condensables are drawn into the top bonnet from the condenser tubes. A steam distribution manifold is suspended from the heat exchange section frame perpendicular to the longitudinal axis of the heat exchange panels and beneath a center point of the heat exchange panels and delivers steam to each heat exchange panel via a single steam inlet located at a center point of each bottom bonnet.

A vertical bundle air-cooled heat exchanger, a finned tube assembly for an air cooled condenser and method for forming the same, and a system for removing thermal energy generated by radioactive materials. In one aspect, an air cooled condenser sized for industrial and commercial application includes an inlet steam distribution header for conveying steam, a condensate outlet header for conveying condensate, an array of tube bundles each having a plurality of finned tube assemblies having a bare steel tube with an exposed outer surface and a set of aluminum fins brazed directly onto the tube by a brazing filler metal. The steel tubes may be spaced apart by the aluminum fins and have an inlet end fluidly coupled to the inlet steam distribution header and an outlet end fluidly coupled to the outlet header. A forced draft fan may be arranged to blow air through the tube bundles.

The present invention relates to an air-cooled condenser apparatus for condensing a steam flow exiting a turbine from for example a power plant. The air-cooled condenser apparatus comprises a series of condenser modules, each module having a series of compact delta-type heat exchanger units and a series of fans. The air-cooled condenser apparatus further comprises a series of independent frame structures FRS(m) wherein the number of frame structures has a lower limit depending on the number of modules. The invention further relates to a method for manufacturing an air-cooled condenser apparatus comprising steps of manufacturing the delta-type heat exchanger units in the factory, placing the units in a container for transportation and erecting the air-cooled condenser apparatus at a site of installation.
