HEAT EXCHANGER Russian patent published in 2023 - IPC F28D7/16 F28F1/42 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat exchangers and can be used in processes in various industries, agriculture and public utilities. The heat exchanger consists of outer and inner tubes having an inlet and outlet of the outer tube, as well as an inlet and outlet of the inner tube, and flanges for connecting additional sections. In this case, the inner tube and the outer tube have helical grooves with the same pitch and depth of the groove, and the helical groove of the inner tube is oppositely directed to the helical groove of the outer tube. It is also possible to connect additional sections to the heat exchanger.

EFFECT: intensification of heat transfer by increasing the heat transfer coefficient.
