VERTICAL SHELL-AND-TUBE HEAT EXCHANGER Russian patent published in 2019 - IPC F28D7/16 F28F9/02 

FIELD: heating equipment.

SUBSTANCE: technical solution relates to heat engineering, namely to apparatus, preferably large diameter and / or high unit power for performing heat exchange of liquid and gaseous media, and can be used in technological processes in various fields of national economy, including oil refining and petrochemical. In vertical shell-and-tube heat exchanger there is a perforated cover with a gap in relation to lower tube plate, forming a distribution chamber, in which to form an annular header there is a shell with uniformly fixed on it L-shaped branch pipes of different length, free ends of which, passing through the central hole of the perforated cover, are located along concentric circles, and in the remaining openings of the perforated cover there are vertical branch pipes which, like the L-like ones, are connected to the annular header and equipped with perforated baffles with shaped edges.

EFFECT: improving efficiency and uniformity of distribution of flow of tube space medium.
