Abstract:
An air-cooled condenser comprising:a distributing chamber for distributing a vaporous medium to be condensed, a condensate collecting chamber and finned tubes with fins on air side, said finned tubes being connected in parallel manner between said distributing chamber and said condensate collecting chamber; andwherein each of said finned tubes comprises two substantially parallel side walls and exterior closings connecting said side walls, wherein there are longitudinal separation walls connected to said side walls and dividing an inner space of said finned tubes into longitudinal channels, and wherein at least one of said separation walls has thereon one or more breakthroughs for allowing the flow of said medium between neighboring channels, and wherein at least one of said channels is divided by a closure element formed within said channel, wherein there is at least one breakthrough formed in a separation wall near said closure element, wherein said condenser is divided into a main condenser portion for conducting said medium from said distributing chamber to said condensate collecting chamber, and an after-cooler portion for conducting said medium from said condensate collecting chamber towards said distributing chamber to an air extraction pipe.
