TUBULAR HEAT EXCHANGER Russian patent published in 2020 - IPC F28D7/00 F28D7/16 

FIELD: heating equipment.

SUBSTANCE: invention relates to heat engineering and can be used in turbine construction, as well as in power engineering and engine building in axially symmetric structures, such as aircraft gas turbine engines and power plants. In the tubular heat exchanger, the heat exchanger matrix is an axially symmetric structure of tubes grouped into flat sections, each section consisting of several tubes and two end elements into which the ends of the tubes exit, sections are laid in layers in planes perpendicular to axis of matrix with alignment of end elements, and are connected through holes in end elements to each other so that tubes located in adjacent layers cross, and end elements form axial channels parallel to axis of matrix.

EFFECT: improving manufacturability and providing repairability of heat exchanger.
