Abstract:
1. Plate-shaped heat exchanger ( 20 , 120 ) for a heat exchange unit ( 40 ) of a chemical reactor ( 60 ), having a substantially box-like flattened structure ( 22 ), with a substantially parallelepiped, rectangular configuration, defining an internal chamber ( 24 ), and comprising an inlet connection ( 28 ) and an outlet connection ( 29 ) for a heat exchange operating fluid into and from said chamber ( 24 ), and a distributor pipe ( 10 , 110 ) of said operating fluid in said chamber ( 24 ), extended in said structure ( 22 ) at a long side ( 22 a ) of it, characterised in that said distributor pipe ( 10 , 110 ) comprises a first tube ( 30 , 130 ) and second tube ( 32 , 132 ), positioned one inside the other, between said tubes, respectively external tube ( 30 , 130 ) and internal tube ( 32 , 132 ), an interspace ( 30 a ) being defined in fluid communication, on one side, with said chamber ( 24 ) through a plurality of openings ( 26 ) provided in the external tube ( 30 , 130 ) of said distributor pipe ( 10 , 110 ), and, on the other side, with the internal tube ( 32 , 132 ) of the same distributor pipe ( 10 , 110 ), said internal tube ( 32 , 132 ) being hydraulically connected to said inlet connection ( 28 ) for the heat exchange operating fluid.
