TUBULAR HEAT EXCHANGER Russian patent published in 2019 - 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 for use in axially symmetric structures, such as aircraft gas turbine engines and power plants. In the tubular heat exchanger the heat exchanger matrix without welded or soldered joints is monolithic and represents an axially symmetric structure of the tubes laid in layers in planes perpendicular to the matrix axis, note also that tubes arranged in adjacent layers are crossed while tube ends are connected with axial channels parallel with matrix axis.

EFFECT: improved manufacturability, reliability and efficiency of heat exchanger.
