Abstract (en)

A heat exchanger (1), wherein the bundle of parallel U-bent tubes (2) is connected via a connection to a first end, where a first hemispherical bonnet (16) distributes the first fluid to the tubes (2) of the first straight section (9), and to a second end, where a second hemispherical bonnet (16) collects the first fluid from the tubes (2) of the second straight section (10), each said connection being made of a tube sheet (11, 12) which is designed to withstand the difference between the second fluid low pressure inside the intershell space (5) and the first fluid high pressure inside the respective bonnet (16), wherein the tube sheet comprises a circular plate (12) having a central circular orifice and wherein the tube sheet further comprises a hemispherical shell (11) located over said orifice and tightly connected to said circular plate (12), so as to make a physical separation between the first fluid and the second fluid.
