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

FIELD: heat engineering.

SUBSTANCE: invention can be used for heating fluid in heat exchangers for two coolants. The heat exchanger comprises a body, with a heat exchange casing installed in it, whereas between the inner surface of the body and the outer surface of the body, a smoke channel is formed, into which combustion products enter. The body of the heat exchanger is made in the form of a pipe with a bottom and a cover, whereas inside it hollow tubes communicating with the smoke channel are vertically placed, the ends of which are fixed in the bottom and the cover of the body; additionally, a partition is vertically fixed inside the body at its bottom for dissecting the fluid medium flow, and sling loops are diametrically oppositely fixed on the outer surface of the cover; on the side surface of the body, inlet and outlet pipes are fixed for supplying fluid to the body, brought outside the body; a fluid outlet fitting is fixed on the body cover, and a drain fitting is fixed on its bottom, whereas said fittings are brought out of the body.

EFFECT: increase in the efficiency of heating the coolant circulating in the heat exchanger.
