HEAT EXCHANGER WITH A LIQUID/GAS MIXING DEVICE WITH IMPROVED CHANNEL GEOMETRY Russian patent published in 2021 - IPC F28D9/00 F28F3/00 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering. The heat exchanger comprises several plates located parallel to each other in such a way so as to form the first row of passages for directing at least one fluid refrigerant medium (F1) and the second row of passages for directing at least one fluid calorigenic medium (F2) to bring it into heat-exchange contact with at least said fluid refrigerant medium (F1). At least one passage of the first row formed between the second plate forming the adjacent passage of the second row and the first plate. The mixing device which is also located in at least above-mentioned first row passage and comprises: at least one first channel for directing the gas phase of a fluid refrigerant medium (F1), at least one second channel for the direction of the liquid phase of the fluid refrigerant medium (F1). The longitudinal section of the second channel, measured parallel to the second plate, is reduced in the direction of said second plate.

EFFECT: achieved is production of high-quality heat exchanger with improved channel geometry.
