PLATE HEAT EXCHANGER WITH HELICAL TURBULATORS FOR GAS TURBINE PLANT Russian patent published in 2024 - IPC F28D9/04 B33Y80/00 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat engineering and can be used for heating liquid or gaseous media, including as a recuperator for gas turbine plants. Heat exchanger consists of three sections (1), (2), (3). Section (2) comprises headers for air supply from the compressor and exhaust gases discharge, section (3) contains air discharge headers from the compressor and exhaust gas supply. Section (1) consists of cylindrical outer housing (4), separating ring (5) and heat exchange elements (6) resting on it, which are made in the form of curved plates (7), in which helical turbulators (8) and (9) are arranged, respectively. Diameter of helical turbulators (8) in the channel for air flow from compressor (11) is 2 times less than the diameter of helical turbulators (9) in the channel for the flow of exhaust gases (10). Sections (2), (3) are located coaxially to section (1) and are made integral by selective laser fusion.

EFFECT: reduced hydraulic resistance in heat exchanger.
