HEAT EXCHANGER COMPRISING A DEVICE FOR DISTRIBUTION OF LIQUID-GAS MIXTURE Russian patent published in 2020 - IPC F28D9/00 F28F3/08 

FIELD: heat exchange.

SUBSTANCE: heat exchanger (1) with plates, comprising a first row of channels (10) for passing at least one cooling fluid medium (F1) and a second row of channels (20) for passing at least one calorific fluid medium (F2), wherein each channel (10, 20) is formed between two successive plates (2) and extends parallel to longitudinal axis (z), at least one mixing device (3), located in at least one channel (10) of the first row, wherein said mixing device (3) is configured to receive liquid phase (61) and gaseous phase (62) of cooling fluid (F1) and distribution of mixture of said phases (61, 62) into said at least one channel (10). According to the present invention, at least one second row channel (20) adjacent to the at least one first row channel (10) comprises a heat exchange structure, divided in longitudinal direction (z) into at least first part (100) and second part (200), which are located nearby along longitudinal axis (z), wherein the second portion extends opposite the at least part of mixing device (3) and is configured to provide a heat exchange coefficient which is lower than the heat exchange coefficient of first portion (100).

EFFECT: disclosed is a heat exchanger comprising a device for distributing a liquid-gas mixture.
